Kamen Rider Series/Heisei Series Phase 2

Heisei Kamen Rider Series Phase 2 (平成仮面ライダーシリーズ第2期), also referred to by fans as the "Neo-Heisei" era, is the current subsection of the second and current era of the Kamen Rider Series, the Heisei period.

The Heisei Phase 2 is specifically used to refer to the post-Decade era, with Kamen Rider Decade having been the 10th Anniversary Kamen Rider show of the Heisei period.

After the Decade series, Kamen Rider is the official term for Riders while pre-Decade Riders have been shown to use "Masked Rider" in official localization releases, merchandise such as the S.H. Figuarts toyline as well as in Kamen Rider 4.

The Heisei Phase 2 started with Decade's successor, Kamen Rider W, which premiered in September 2009 and ended in August 2010. W was followed by Kamen Rider OOO (September 2010 - August 2011), then Kamen Rider Fourze (September 2011 - August 2012), Kamen Rider Wizard (September 2012 - September 2013), Kamen Rider Gaim (October 2013 - September 2014), Kamen Rider Drive (October 2014 - September 2015), Kamen Rider Ghost (October 2015 - September 2016, Kamen Rider Ex-Aid (October 2016 - August 2017), and Kamen Rider Build (September 2017 - August 2018). The current entry in the Kamen Rider Series and the final Heisei series, Kamen Rider Zi-O, premiered in September 2018.

On April 1, 2016, an original remake net series Kamen Rider Amazons was aired. It marks the Heisei Era's first time since Faiz that the franchise has gone back to a darker and more adult oriented style of storytelling, though this series is available only on Amazon Prime and rated R15+. A second season was made in 2017.

Heisei Phase 2 trends
In general= From Wizard onwards= From Gaim onwards=
 * The Heisei Phase 2 era has a differing broadcast schedule for its shows with the schedule of the first half of the Heisei era. This change had been brought about by the shortened episode count of Kamen Rider Decade. The first series of the Heisei revival, Kamen Rider Kuuga premiered in January 2000, and ended in January 2001, being succeeded by Kamen Rider Agito the week after. From then on, every Heisei show until the start of the Heisei Phase 2 era started in late January (or in Ryuki's case, early February) and ended in January of the next year. However, Kamen Rider Decade, which premiered in January 2009, was slated as having only 30 episodes as stated by Masahiro Inoue in an interview in the March 2009 issue of Kindai Magazine. A subsequent interview in Otonafami magazine confirmed that only 30 episodes were filmed, with 31 episodes airing total. Thus, Decade ended in late August (the 30th) and W started in early September (the 6th), and Heisei Phase 2 shows then ended on the last Sunday of August and started on the first Sunday of September; though as of 2014, the last episode of one series is on the last Sunday of September and the first episode of the new series starts on the first Sunday in October.
 * With this new broadcast schedule, the summer movie of every show now premieres during the final weeks of said show and only around a month before the arrival of the new series. Thus, from Kamen Rider Double's introduction in Kamen Rider Decade: All Riders vs. Dai-Shocker (August 2009) to Kamen Rider Wizard's introduction in Kamen Rider Fourze the Movie: Everyone, Space is Here! (August 2012), the Rider of the upcoming show makes his "early-bird cameo". This introduction features the new Rider helping out the current (soon to depart) Rider.
 * Even though Kamen Rider Decade is not a Phase 2 Rider and did not appear in the previous Rider's series, he is the first primary Heisei Rider to make an "early-bird cameo" in a special, which later foreshadows most of the primary Phase 2 Riders appearing in a summer movie.
 * Kamen Rider Gaim's "early-bird cameo" is unique in that instead of making his debut in Wizard's summer movie, he appeared in his two-part epilogue special.
 * Kamen Rider Drive is the first primary Phase 2 Rider, as well as the first primary Heisei Rider since Decade, who does not make a cameo appearance in his predecessor's series.
 * All of the summer movies have the main Rider using all of their forms that debut in the television series, including a movie-exclusive form that is introduced in the movie.
 * Kamen Rider W: CycloneJokerGoldXtreme
 * Kamen Rider OOO: Burakawani Combo
 * Kamen Rider Fourze: Meteor Fusion States
 * Kamen Rider Wizard: Infinity Dragon
 * Kamen Rider Gaim: Black Jimber Arms
 * Kamen Rider Drive: Super Dead Heat Drive & Type Special
 * Kamen Rider Ghost: Darwin Damashii
 * Kamen Rider Ex-Aid: Creator Gamer
 * Kamen Rider Build: Cross-ZBuild Form
 * With the exception of Double, each Hyper Battle DVD also has the main Rider gaining access to a form that is only exclusive to said special.
 * Kamen Rider OOO: Takagaruba, Takatoragaru, & Takatorazou
 * Kamen Rider Fourze: Rocket Drill States
 * Kamen Rider Wizard: Beast Mantle
 * Kamen Rider Gaim: Fresh Orange Arms
 * Kamen Rider Drive: Type High Speed, Type High Speed Vegas, & Type High Speed Flare
 * Kamen Rider Ghost: Ikkyu Damashii
 * Kamen Rider Ex-Aid: Bike Action Gamer Level 0
 * Kamen Rider Build: KumaTelevi Form
 * Another result of the new broadcast schedule is that while the bulk of early Heisei series ran alongside one particular Super Sentai series, Heisei Phase 2 shows find themselves paired up with two Sentai shows across their run, the first half of the series airs alongside the second half of their first Sentai partner, while the second half of the series airs alongside the first half of their second partner.
 * The official translation of the Kamen Rider Series, as seen on the series' titles, was changed from "Masked Rider" (e.g. Masked Rider Decade) to "Kamen Rider" (e.g. Kamen Rider W).
 * As started by Kamen Rider W, it is a recurring trend that only two Riders appear in the broadcast run: the Primary Rider and the Secondary Rider. Though, every series has had more new Riders appear through expanded universe material, particularly their own summer movies, which go on to appear again occasionally. The main series only deals with the Primary and Secondary Riders. This trend stopped in Kamen Rider Wizard, as each season after that would introduce more than two Riders throughout the course of the series, with Gaim and Ex-Aid starting off with multiple Riders from the beginning. Movie-exclusive Riders do not count.
 * Kamen Rider W: Double & Accel (as well as Joker)
 * Kamen Rider OOO: OOO & Birth (as well as Proto-Birth)
 * Kamen Rider Fourze: Fourze & Meteor
 * The transformation devices of Riders in the Heisei Phase 2 era are given consistent names, being referred to as "Drivers" (e.g. Double Driver, OOO Driver, Fourze Driver, WizarDriver, Sengoku Driver, Drive Driver, Ghost Driver, Gamer Driver, Build Driver, and Ziku-Driver.). Driver was previously used to refer to the transformation gears of the Kamen Riders from Kamen Rider 555 and Kamen Rider Decade.
 * The Mage's Belt in Kamen Rider Wizard, the Mega Ulorder in Kamen Rider Ghost and the Gashat Gear Dual in Kamen Rider Ex-Aid are anomalous breaks in this trend.
 * Each Heisei Phase 2 series has its own set of Collectible Devices, first seen with the Advent Cards in Kamen Rider Ryuki, with the recent tradition being kicked off by the Rider Cards of Kamen Rider Decade, which were used by Decade to access the power of previous Kamen Riders. As with Decade, the Heisei Phase 2 Kamen Riders use their collectible devices for various purposes, such as changing into their various forms, using special attacks, and other techniques. These collectible devices also work very well with merchandise, each set of collectibles has had their own "Legend Rider" range featuring the likenesses of previous Kamen Riders, some of which appear in the arcade game Kamen Rider Battle: Ganbaride and Movie War crossovers.

 * Starting with Decade's Bandai: FFR series, each Heisei Phase 2 season would have a toyline of figures which simulate a transformation gimmick unique to each season, commonly referred to by fans as "gimmick figures". Although there was a precursor with Kamen Rider Kabuto's Cast Off Rider series, which simulated the Cast Off gimmick, gimmick figures in the Heisei Phase 2 era were much more prominent.
 * Kamen Rider Decade: Bandai: FFR series, which simulates Decade's Final Form Ride ability.
 * Kamen Rider W: W Form Change series, which simulates Double's half-changes gimmick.

 * Kamen Rider Drive: Tire Koukan series, which simulates the Tire and Signal Exchange abilities of Drive, Mach, and Chaser.
 * Kamen Rider Ghost: Ghost Change series, which simulates the interchangeability of various Riders' Transients and Parka Ghosts.
 * Kamen Rider Ex-Aid: Level UP Rider Series, which simulates the Riders' Level Up function.
 * Kamen Rider Build: Bottle Change Rider Series, which simulates Build's Best Match changing gimmick.
 * Kamen Rider Zi-O: Rider Kick's Figure series, which simulates Zi-O's and Geiz's Armor Time gimmick. This line also includes Riders from past series as well.

 * With the exception of Build, each Heisei Phase 2 series has a piece of arsenal that can assume at least three different modes.
 * Kamen Rider W: The HardBoilder can also assume its HardTurbuler and HardSplasher modes, aside from its default motorcycle mode.
 * Kamen Rider OOO: Aside from its Machine Vendor and Machine Bike modes, the Ridevendor also becomes the Toride Vendor when combined with the Tora Candroid.
 * Kamen Rider Fourze: The Powerdizer, aside from its default robot mode, can also assume Vehicle Mode and Tower Mode.

 * Kamen Rider Zi-O: The Zikan Despear has three modes: spear, scythe and cane.

 * Kamen Rider W: "Now, count up your sins!"
 * Kamen Rider Fourze: "Space is here! Kamen Rider Fourze! Let's settle this one-on-one!"

 * Kamen Rider Zi-O: "I think I can do this now!"
 * With the exception of Baron and Specter (who says his catchphrase "I'll show you my way of life!" prior to finishing off an enemy), the Secondary Riders also have their own unique pre-battle catchphrase.
 * Kamen Rider Accel: "Now, let's break through!"
 * Kamen Rider Birth: "Now, time to cash in!" (Date only)

 * Kamen Rider Mach: "Searching... destroying... both done, at mach speed! Kamen Rider... Mach!"
 * Kamen Rider Brave: "Commencing Bugster removal operation."
 * Kamen Rider Cross-Z: "I feel unbeatable at this moment!"
 * The lead Rider usually has unique rules involving his forms:
 * The second new form he obtains debuts in the first part of a two episode arc instead of the second (e.g. OOO's Latorartar Combo, Fourze's Fire States, Wizard's Hurricane Dragon, & Drive's Type Technic).
 * The Super Form, or a version of the Super Form (or in Ghost and Build's cases the upgrade form), first debuts in the Movie War film, and then usually appears around episode 20 of the series, with Fourze, Gaim, and Drive being the exceptions.
 * The Final Form debuts in episode 32, except for Wizard's Infinity Style (which debuted in episode 31) and Drive's Type Tridoron (which debuted in episode 33), followed by Ghost Mugen Damashii (which was briefly seen in episode 33 and made its full debut in episode 34), Ex-Aid Muteki Gamer (which debuted in episode 36), and Build Genius Form (which debuted in episode 39).
 * With the exception of Double, the lead Rider's forms have some sort of title.
 * Kamen Rider OOO: Combos
 * Kamen Rider Fourze: States
 * Kamen Rider Wizard: Styles
 * Kamen Rider Gaim: Arms
 * Kamen Rider Drive: Types
 * Kamen Rider Ghost: Damashii

 * Kamen Rider Zi-O: Zi-O's default form, along with Build Armor & Ex-Aid Armor
 * The lead Rider and secondary Rider(s) display some kind of cross-compatibility.
 * ​Kamen Rider W: Kamen Rider Double CycloneAccelXtreme was hypothesized to be possible if Ryu Terui took Shotaro Hidari's place as Double.
 * Kamen Rider OOO: Eiji Hino transforms into Kamen Rider Birth in Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals.
 * Kamen Rider Fourze: Kamen Rider Meteor is able to use Fourze's Circle Astroswitches to activate finishers. Kamen Rider Fourze Meteor Fusion States & Meteor Nadeshiko Fusion States use the power of Meteor and Nadeshiko, utilizing the Meteor and Nadeshiko Astroswitches, granting Fourze the Meteor Galaxy.
 * Kamen Rider Wizard: Exclusively in the Hyper Battle DVD, Kamen Rider Wizard accesses Falco Mantle and Beast Mantle using Beast's Falco and Buffa Wizard Rings.
 * Kamen Rider Gaim: All Armored Riders can utilize any Lockseed compatible with their Driver. This has been demonstrated by Gaim using Banana Arms, Donguri Arms, and Durian Arms, as well as Baron, Ryugen, and Zangetsu interchanging Ichigo Arms, Melon Arms, Kiwi Arms, Banana Arms, Pine Arms, Budou Arms, and Mango Arms, along with Suika Arms being used by multiple Riders throughout the series. Additionally, Gaim's Kiwami Arms can summon any Arms Weapon.
 * Kamen Rider Drive: Multiple Shift Cars and Signal Bikes combine the powers of different Riders.
 * The Shift Dead Heat Car allows Drive and Mach to access a form that combines both of their powers.
 * Mach uses the Signal Chaser to merge his power with Chaser's.
 * The Tridoron Key is used in the Mach Driver Honoh to access Drive's Super Dead Heat form, which is themed after Mashin Chaser.
 * In the absence of the Drive Driver, Drive has used the Mach Driver Honoh to become Deadheat Drive.
 * The Shift Ride Crosser Car allows Mach to access a form that combines his power with Chaser's.
 * Kamen Rider Ghost: Ghost, Specter, and Necrom can use any of each other's Eyecons, as seen when Specter accessed Edison Damashii and Necrom Damashii, and Ghost accessed Toucon Houdini Damashii. Ghost's Grateful Damashii also combines the power of all 15 Eyecons.
 * Kamen Rider Ex-Aid
 * Drago Knight Hunter Z is a Rider Gashat shared by the main four Riders. They each can use it on their own to gain all the armor of the Hunter Gamer, or it can duplicate to be used between multiple Riders and access stronger Rider-specific forms.
 * The Gashat Gear Dual β is a device shared between Brave and Snipe to access their own Level 50 forms.
 * On multiple occasions a Rider has used another's Gashat to activate a finisher.
 * If a Rider or Ride-Player possesses a Gashat tied to a Gashacon Weapon, they can use the weapon without having to activate the Gashat.
 * Kamen Rider Cronus has the ability to use any Gashacon Weapon, however, this has only been demonstrated while using the Gamer Driver instead of the Buggle Driver II.
 * Ex-Aid once stole the Gashacon Sword out of Brave's hands.
 * Kamen Rider Build: The Dragon Fullbottle is used by Kamen Rider Build with the Lock Fullbottle to access KeyDragon Form, and is used by Kamen Rider Cross-Z to access his default form.
 * Kamen Rider Zi-O: The Ridewatches based on the past Heisei Riders can be used by either Kamen Rider Zi-O or Kamen Rider Geiz.
 * In every Heisei Phase 2 series, the Riders have some sort of nickname for their finishing attacks, which are announced by their transformation devices and various weapons.
 * Kamen Rider W: Maximum Drive
 * Kamen Rider OOO: Scanning Charge/Giga Scan/Putotyranno Hissatsu (OOO) & Cell Burst (Birth)
 * Kamen Rider Fourze: Limit Break
 * Kamen Rider Wizard: (Attack name) Strike
 * Kamen Rider Gaim: Squash/Au Lait/Sparking (Armored Riders), Fruits Charge (Gaim, Zangetsu, New Generation Rider Baron & Bujin Gaim), Squash/Sparking (New Generation Riders), & Energy (New Generation Riders)
 * Kamen Rider Drive: Full Throttle
 * Kamen Rider Ghost: Omega (Attack name)
 * Kamen Rider Ex-Aid: Critical (Attack name)
 * Kamen Rider Build: Vortex (Attack name) (Build Driver), (Attack name) Break/Finish
 * Kamen Rider Zi-O: Time (Attack name) (Ziku-Driver)
 * In the Heisei Phase 2 shows, the lead Rider and the secondary Rider often have similar yet distinct powers, abilities, and themes. This trend began with Kamen Rider Decade, where both Riders used Rider Cards, with the difference between them being that Decade has a smaller selection of cards, but can transform into them with full access to their powers, while Diend has access to more cards, but can only summon copies of Riders without their full range of powers. This continues in each of the following series.
 * Kamen Rider W: Kamen Rider Accel uses Gaia Memories in his own personal Driver to access a form with his own overarching theme (motorcycles).
 * Kamen Rider OOO: Kamen Rider Birth expands the coin concept into a motif, expending cell medals to access his own built-in weapons.
 * Kamen Rider Fourze: Kamen Rider Meteor uses his own Driver and Astroswitch to transform, expressing the space theme in the form of his meteor motif and ability to channel planets as weapons.
 * Kamen Rider Wizard: Kamen Rider Beast uses his own Driver and Wizard Rings to transform, using the mythical Chimera to convey an animal theme along with the magic theme.
 * Kamen Rider Gaim: Each Rider bears their own warrior motif (samurai, knight, Chinese soldier, gladiator, etc.) and uses their own Lockseeds to gain unique fruit armor.
 * Kamen Rider Drive: Kamen Rider Mach uses his own Driver, with Signal Bikes instead of Shift Cars, to access his bike-themed Rider form and street sign themed abilities.
 * Kamen Rider Ghost: Kamen Rider Specter's design is a minor variation on Ghost's, using his own personal Eyecon and other Heroic Eyecons to access his own forms.
 * Kamen Rider Ex-Aid: Secondary Riders use other games to transform, each with their own themes and weapons.
 * Kamen Rider Build: Kamen Rider Cross-Z uses his own device to adapt the Build Driver's two slots into one, and transforms with the Dragon Fullbottle, also used by Build to access KeyDragon Form.
 * Kamen Rider Zi-O: While Kamen Rider Zi-O's forms and arsenal are themed after katakana, Geiz's forms and arsenal are conversely themed after hiragana.
 * Having previously been the suit actor of the majority of primary riders in the early Heisei era (with the exceptions being Kuuga and Hibiki), Seiji Takaiwa has served as the suit actor for every Primary Rider in the Heisei Phase 2 era so far.
 * Fighting alongside Takaiwa is Eitoku who, starting with Kamen Rider Diend in Decade, has gone on to be the suit actor for every secondary Heisei Phase 2 Rider, except for Beast, Mach, Specter, and Brave Level 2 all of whom are suit-acted by Jun Watanabe.
 * A resurgence of crossovers, as the early Heisei era rarely featured crossovers between series (one rare example is the Hyper Battle DVD Kamen Rider Ryuki: Ryuki vs Kamen Rider Agito). Kamen Rider Den-O & Kiva: Climax Deka was the first Heisei crossover movie (April 2008), though that it was largely due to the popularity of Kamen Rider Den-O. Being an anniversary series, the very premise Kamen Rider Decade involved various elements of the Kamen Rider Series coming together.
 * The Movie War series, starting with Kamen Rider × Kamen Rider W & Decade: Movie War 2010 (December 2009), each Heisei Phase 2 series has a Movie War crossover with the previous series, premiering in December, somewhere in between episodes 10 and 15 of the current series. Just as the summer movies introduce the primary Rider of the new series, the Movie War features an "early-bird cameo" by the Secondary Rider of the current series. As with the primary Rider's introduction in the summer movie, the new secondary Rider appears in costume only, however their were chances that the user of the secondary Rider would appear in both civilian and Rider form. Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core (December 2010) featured a crossover between Kamen Riders Double and OOO, the first two primary riders of the Heisei Phase 2 era, followed by Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max (December 2011), which also featured Double and the Seven Legendary Riders as well as Fourze and OOO, teaming the first three Heisei Phase 2 riders with the seven original Showa riders. This is set to be topped by the Kamen Rider × Kamen Rider Wizard & Fourze: Movie War Ultimatum (December 2012), which featured Kamen Rider Wizard teaming up with not just Fourze, but all three of the previous Heisei Phase 2 primary Riders and their secondary Riders as well.
 * Other theatrical Heisei Phase 2 crossovers include the Kamen Rider Series 40th Anniversary movie, OOO, Den-O, All Riders: Let's Go Kamen Riders, and the first crossover movie with Super Sentai, .
 * Foundation X, which was first introduced as the "evil organization" of Kamen Rider W, continues to have a (albeit reduced) presence in the other Heisei Phase 2 Kamen Rider shows, having appeared in episodes of Kamen Rider Fourze and as the villains of Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max, and in Kamen Rider Fourze the Movie: Everyone, Space is Here!. Foundation X seemed to have disappeared as of Kamen Rider Wizard, but after a cameo in Kamen Rider Brave: ~Let's Survive! Revival of the Beast Rider Squad!~, they returned as a villainous influence in Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders. Their presence is reminiscent of the influence the Great Leader (originally the Great Leader of Shocker) had on later evil organizations in the Showa era. In Foundation X's footsteps, seasons from Wizard onward have had evil organizations exerting villainous influence in some capacity:
 * Kamen Rider Gaim: Yggdrasill Corporation
 * Kamen Rider Drive: National Bureau of Defense and Neo-Shade
 * Kamen Rider Ghost: Deep Connect
 * Kamen Rider Ex-Aid: Genm Corp. and Next Genome Institute
 * Kamen Rider Build: Faust and Namba Heavy Industries Ltd.
 * Each Heisei Phase 2 era villain group has their own Henchmen squad.
 * Kamen Rider W: Masquerade Dopants
 * Kamen Rider OOO: Waste Yummies
 * Kamen Rider Fourze: Stardust Ninja Dustards
 * Kamen Rider Wizard: Ghouls
 * Kamen Rider Gaim: Elementary Inves. Also the Kurokage Troopers, though they were not actual henchmen.
 * Kamen Rider Drive: Low-Class Roidmudes
 * Kamen Rider Ghost: Gamma Commandos
 * Kamen Rider Ex-Aid: Bugster Virus
 * Kamen Rider Build: Guardians
 * Each series' monsters are either summoned or transformed by a Collectible Device, usually another version of the main hero's Collectible Devices. Wizard is an exception, as only the Ghouls are summoned by Magic Stones, as well as Build's Smash being transformed by the Steam Blade's Devil Steam attack (although, in a reversal, their essences are retrieved in Empty Bottles transforming them into Smash Bottles which can transform a former victim back into a Smash).
 * Kamen Rider W: Gaia Memories
 * Kamen Rider OOO: Cell Medals
 * Kamen Rider Fourze: Zodiarts Switch
 * Kamen Rider Wizard: Magic Stones
 * Kamen Rider Gaim: Unripe Lockseeds
 * Kamen Rider Drive: Viral Cores
 * Kamen Rider Ghost: Gamma Eyecons
 * Kamen Rider Ex-Aid: Prototype Gashats
 * Kamen Rider Build: Smash Bottles
 * Kamen Rider Zi-O: Another Ridewatches
 * Riders after Fourze and before Drive have their own title rather than Kamen Rider in their own universe or timeline. This first happened in Hibiki, where the Riders were being called Oni to match the heavy Japanese mythology-theme of the series.
 * Kamen Rider Wizard: Magicians
 * Kamen Rider Gaim: Armored Riders & New Generation Riders
 * With the exception of OOO, Fourze, Ex-Aid, and Build, the second-to-last (or in Wizard's case, third-to-last) episode of each Heisei Phase 2 series is the conclusion to its main storyline while the actual finale is an epilogue.
 * Kamen Rider W: The Abandoned U/Eternal Partners (#48 of 49)
 * Kamen Rider Wizard: The Last Hope (#51 of 53)
 * Kamen Rider Gaim: Fate's Victor (#46 of 47)
 * Kamen Rider Drive: Who Will You Entrust the Future to, My Friend? (#47 of 48)
 * Kamen Rider Ghost: Infinity! Power of Humanity! (#49 of 50)
 * With the exception of Gaim, the finale of each Heisei Phase 2 series contains a link to the next series.
 * Kamen Rider W: In The Abandoned U/Eternal Partners, which was technically the second-to-last episode but served as the finale (the true final episode took place one year in the future), Foundation X scraps their research on Gaia Memories and instead takes an interest in O Medals.
 * Kamen Rider OOO: In Finale: The Medals of Tomorrow, Underwear, and Arms Held, Kengo Utahoshi and Yuki Jojima appear with an Astroswitch. This is the first time characters from the next series are seen.
 * Kamen Rider Fourze: In Final Episode: Youthful Galaxy, Kamen Rider Wizard himself, Haruto Soma, appears out of costume wearing his Flame Style Wizard Ring.
 * Kamen Rider Wizard: The Kamen Rider Rings and Neverending Story is a two-part crossover with all fifteen Heisei/Heisei Phase 2 main Riders, including Gaim.
 * Kamen Rider Drive: Like Gaim, Ghost makes an appearance in Drive's last two episodes.
 * Kamen Rider Ghost: Kamen Rider Genm makes an appearance in Ghost's last two episodes with Ex-Aid also appearing in Ghost's final episode.
 * Kamen Rider Ex-Aid is unique as although Kamen Rider Build makes an appearance in Ex-Aid, he only appears in Ex-Aid's second-to-last episode, which comes before the official finale.
 * Kamen Rider Build: In the finale, after the two worlds are merged, Sento Kiryu finds the Cross-Z Ridewatch in his possession.
 * Each Heisei Phase 2 series has had an update to the video game Kamen Rider: Climax Heroes, which was first released for Kamen Rider Decade and the 10th anniversary of the Heisei Kamen Rider Series. These initially had the title format of Kamen Rider Climax Heroes (show name), but Kamen Rider Wizard subverted that trend and Kamen Rider Gaim doesn't have its own Climax Heroes, as the fighting game series is replaced by a Dynasty Warriors like game called Kamen Rider Battride War after the last Climax Heroes since the appearance of Kamen Rider Wizard. Ghost, however, brought back the Battride War series in the form of Kamen Rider: Battride War Genesis, while Build brought back the Climax Heroes series in the form of Kamen Rider: Climax Fighters. Drive and Ex-Aid are the only two seasons to have no games from either game series produced.
 * Kamen Rider W: Kamen Rider: Climax Heroes W
 * Kamen Rider OOO: Kamen Rider: Climax Heroes OOO
 * Kamen Rider Fourze: Kamen Rider: Climax Heroes Fourze
 * Kamen Rider Wizard: Kamen Rider: Super Climax Heroes and Kamen Rider: Battride War
 * Kamen Rider Gaim: Kamen Rider: Battride War II
 * Kamen Rider Ghost: Kamen Rider: Battride War Genesis
 * Kamen Rider Build: Kamen Rider: Climax Fighters
 * Kamen Rider Zi-O: Kamen Rider: Climax Scramble Zi-O
 * Each Heisei Phase 2 series features pertinent ally characters with a mysterious past that is linked to the main villains of the show. Most of them are all killed before their series concludes, but come back to life some time later, with the exception of Ankh and Koyomi, as they were technically aren't "alive" before the series started. However, Ankh was shown to have been possibly revived in the future as seen in Movie War Mega Max, before making a full (albeit temporary) return in Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders. There is a rare exception where Mai as Woman of the Beginning was not killed in the traditional sense.
 * Kamen Rider W: Raito "Philip" Sonozaki
 * Kamen Rider OOO: Ankh
 * Kamen Rider Fourze: Kengo Utahoshi
 * Kamen Rider Wizard: Koyomi Fueki & WizarDragon
 * Kamen Rider Gaim: Woman of the Beginning
 * Kamen Rider Drive: Mashin Chaser & Krim Steinbelt
 * Kamen Rider Ghost: Sennin, Makoto Fukami & Kanon Fukami
 * Kamen Rider Ex-Aid: Poppy Pipopapo
 * Kamen Rider Build: Sento Kiryu, Ryuga Banjou, Misora Isurugi & Soichi Isurugi
 * Each Heisei Phase 2 series has a Female Kamen Rider, starting with Decade's Kamen Rider Kiva-la.
 * Kamen Rider W: Akiko Narumi (dream only)
 * Kamen Rider OOO: Erika Satonaka (Net Movie only)
 * Kamen Rider Fourze: Nadeshiko Misaki
 * Kamen Rider Wizard: Mayu Inamori & Koyomi Fueki (Movie War only)
 * Kamen Rider Gaim: Yoko Minato
 * Kamen Rider Drive: Kiriko Shijima (Special DVD only)
 * Kamen Rider Ghost: Jey (Summer Movie only) & Alia
 * Kamen Rider Ex-Aid: Poppy Pipopapo & Nico Saiba
 * Each Secondary Rider generally has a more major role in the series in the Heisei Phase 2 era than the previous Secondary Riders, usually starting out as anti-heroes but then working together with the Primary Rider later on in the series.
 * Only Kamen Rider Birth & Cross-Z break this trend, with Birth being a generally heroic Rider from the start and Cross-Z being a character who was a helpful ally of the protagonist from episode 1.
 * Usually, the Secondary Rider's Final Form debuts before the lead Rider's Final form.
 * Kamen Rider OOO: Birth Day debuted 6 episodes before OOO Putotyra Combo.
 * Kamen Rider Fourze: Meteor Storm debuted 4 episodes before Fourze Cosmic States.
 * Kamen Rider Wizard: Beast Hyper debuted a mere 2 episodes before Wizard Infinity Style.
 * Kamen Rider Ghost: Deep Specter debuted 6 episodes before Ghost Mugen Damashii.
 * Kamen Rider Build: Cross-Z Magma debuted 8 episodes before Build Genius Form.
 * However, there are a few exceptions to this:
 * Accel Trial appeared after Double CycloneJokerXtreme, similarly to the Heisei Phase 1 Riders.
 * Baron and Mach both received their final forms only in the final few episodes of their respective seasons.
 * Brave Legacy Gamer Level 100 debuted one episode after Ex-Aid Muteki Gamer.
 * With the exception of OOO, Gaim, Drive, Ghost, and Ex-Aid (OOO instead evolving his default Main Form, Tatoba Combo, into his second Final Form, Super Tatoba Combo), each lead Rider evolves their Final Forms into Extra Final Forms in the Summer Movie, while Fourze and Wizard evolve their Extra Final Forms into Ultimate Forms in the Movie War films.
 * Kamen Rider W: Double's CycloneJokerXtreme evolves into CycloneJokerGoldXtreme.
 * Kamen Rider Fourze: Fourze's Cosmic States evolves into Meteor Fusion States by combining with Meteor, then into Meteor Nadeshiko Fusion States by combining with Nadeshiko.
 * Kamen Rider Wizard: Wizard's Infinity Style evolves into Infinity Dragon, then into Infinity Dragon Gold.
 * Each series had lasted at least 47 episodes on average. Kamen Rider Wizard had 53, making this series the longest of all the Heisei Rider series. By contrast, Kamen Rider Gaim had exactly 47, making this series the shortest of all the Heisei Phase 2 Rider series at that time, if only barely qualifying. This record was broken by Kamen Rider Ex-Aid, which had only 45 episodes.
 * Starting with the premiere of  in 2012, the Rider series draw a greater connection with their rival franchise Super Sentai; furthered with the introduction of a TV special combining both franchises from Gaim. This was originally done prior with the World of Shinkenger cross-over during Kamen Rider Decade where the current Rider and Sentai squads encountered each other in a two-part story that primarily aired in KR but spilled over into several Sentai episodes around the same time. Each of these movies generally feature a combination between a Sentai mecha and a Rider's device. In the third Taisen series, Den-O is the one who rides the Sentai mecha, instead of Gaim, which is also making him the first Phase 1 Heisei Rider to do so.
 * : Rocket Drill Go-Buster Oh
 * : Kyoryuzin Miracle Combination
 * : ToQ-Oh Kyoryuzin feat. DenLiner
 * : Shurikenjin Tridoron
 * Kamen Rider Ghost and  break the trend as the Taisen film was replaced with a Kamen Rider anniversary film and as such did not feature a combination. Instead, it reverted back to the traditional crossover episodes similar to Decade and Shinkenger.
 * Though Kamen Rider Ex-Aid and  reverted back to the traditional Taisen film format, the endgame only had Ex-Aid Maximum Gamer Level 99 grow gigantic to match KyurenOh's size, and did not feature a combination.
 * Due to the cancellation of the Taisen series, it is likely that future Super Hero Time pairings (starting from Kamen Rider Build and ) will not feature any more crossovers.
 * This is the first phase to have the current Riders' primary monsters work together with the main heroes since Ryuki, Blade, and Kabuto. The current Riders' main villains only temporarily help the heroes in some movies outside of the Super Hero Taisen movie series.
 * Kamen Rider W
 * Main: It all started with Kirihiko at the time of his death for betraying the Sonozaki family and siding with greater goods instead. Most of Phillip's family, the Sonozaki family (sans Ryubee), become this at the time of their deaths. Although the family's pet cat Mick is the only surviving member of the family, now residing in the Narumi Detective Agency.
 * Movie
 * W Returns: Before the Summer movie, NEVER was this until Katsumi's lover Mina was thought to be killed along with the other Quarks who were actually killed, causing Katsumi to go insane and seek revenge against Foundation X and the Sonozaki family for not only rejecting them for being failed experiments, but also killing every single Quark. However, this caused them to become a group of terrorists against humanity, such as killing anyone who wants a peaceful life.
 * W Forever: Before the Sonozaki's full redemption after the movie, Ryubee and his family aid the current Riders stop the fallen, yet misguided NEVER not only disable all of the T1 Gaia Memories, but also kill all leaving beings within Futo as it is supposed to be meant to kill anything related to the Sonozaki family and Foundation X.
 * Kamen Rider OOO
 * Main: Ankh is the first monster to help the current Rider most, as well as the first monster to redeem himself after remembering Eiji's kindness is much better than the First OOO was.
 * Movie
 * OOO Wonderful: Maki and the Greeeds assist OOO, Ankh, and Date defeat Gara for stealing all of their Core Medals and leading them to be powerless.
 * Kamen Rider Fourze
 * Main: A rare example for some former/redeemed monsters becoming a friend to the primary Riders after realizing their mistakes, including as part of the lessons for the abusers/bullies/human shields who turned the monster into an actual one and attacks them. Ran Kuroki on the other hand once after realized her mistake for not trusting the seniors whom she didn't know after seeing her friend Haru become one like how their old seniors did back in their middle school days, then after being forced into becoming a Zodiarts, she became as a heroine instead of a villainous like the other previous Zodiarts.
 * Movie
 * Fourze the Movie: The primary monsters like Hayami and Tatsugami, despite their villainous ambitions, do care for Earth when the Space Ironmen siblings reveal themselves to destroy Earth, along with its inhabitants, including the monsters as well. Although Gamou is interested in how the Kamen Rider Club will be able to stop the Space Ironmen siblings from destroying Earth, he still cares for his home planet, thus aiding the current Riders to stop the Space Ironmen siblings.
 * Movie War: Saburo was this at first, before redeeming himself by telling his teacher to prove his friendship towards him by throwing the Fourze Driver as sacrifice. Thus taking a namesake of the legendary heroes outside Kamen Rider known as the new Inazuman II, evolved of his first form, Sannagiman. In the end, he reformed the Monster Club as part of the Super Hero support club for the Kamen Rider Club.
 * Kamen Rider Wizard
 * Main: The current Riders' inner Phantom, WizarDragon and Beast Chimera, was this until they started to like the inside of their hosts' body due to having an ideal of pureness and hope, especially as seen in the Movie War where the Phantom's hosts' place where the Riders' inner Phantoms becomes similar to outside world, thus having the Riders' Phantom started to like in their hosts' pure places.
 * Kamen Rider Gaim
 * Main: At first, the Inves can only be summoned by a person, including by the Riders via Lockseed(s) during an Inves Game, until the Inves Game is closed due to the Helheim infection, in which civilians thought that the running wild were caused by the Beat Riders (which was seen caused by Peko at first), but unknown to all people that it was revealed to be an Inves that has escaped from Helheim Cracks from unknown locations, the Lockseed can be hacked to summon them freely, such as being used for crimes. In the end, those who possess the Over Lord Inves blood like Kouta, then Kaito who transformed into a pure Over Lord class Inves, can summon most of the Inves freely without any uses for Lockseeds.
 * Kamen Rider Drive
 * Main: Most of the Roidmudes who want to have their peaceful life like humans are these. Chase on the other hand was the first one to do so, prior to being brainwashed temporarily until he was finally rescued by Drive Type Formula and Kiriko, thus redeeming his sins when he was brainwashed into Mashin Chaser, as Kamen Rider Chaser. Although when Chase was Mashin Chaser, he temporarily helped Drive and the other Rider heroes to defeat Kamen Rider Lupin and Megahex. Later, Heart and Medic assist the three main Riders in their battle against Tenjuro Banno, with Heart and Drive destroying the Sigma Circular.
 * Movie
 * Movie War Full Throttle: Heart and Brain temporarily helped the primary Rider heroes. First up against Zoroku Tojo (now in body of ZZZ & known as Kamen Rider Lupin) for stealing the Roidmudes' data for himself, then Megahex who also had a bit of the same motives as Zoruku, but wanted to assimilate any species into like that robot.
 * Kamen Rider Ghost
 * Main: The Gazai Gamma, originally used by Igor as a pawn in the Demia Project, later defects from the Gamma, joining the Mysterious Phenomenon Institute and assisting the Kamen Riders. Later, Alain, having been framed for killing his father, becomes a renegade and now sides with Ghost and Specter in fighting the Gamma.
 * Kamen Rider Ex-Aid
 * Main: Poppy Pipopapo is a Bugster derived from DoReMiFa Beat's game data, programmed to assist the Kamen Riders in CR. This was until her temporary brainwashing by Ren Amagasaki. Kuroto Dan would later assist CR after his revival, followed by Parado who joins the other Kamen Riders later on in order to end Masamune Dan's ploy with Kamen Rider Chronicle.
 * Kamen Rider Build
 * Main: Many of the Smash encountered early on in the series were actually innocent victims turned into monsters by Faust, and most of these individuals would later assist them in some capacity later on. Gentoku Himuro, a leading member of Faust, originally fought against the Kamen Riders as Night Rogue before eventually joining them in saving the world from Evolto after a series of events which included his defection to Seito, the death of his father and eventually his betrayal of Namba Heavy Industries Ltd.
 * The main Rider will have some sort of disaster befall them before attaining the Final Form. This began since Kamen Rider Decade.
 * Kamen Rider Decade: Tsukasa was unable to use any of his Rider Cards in the World of Negatives as they were all blacked out.
 * Kamen Rider W: Due to Philip's body evolving, Shotaro is unable to keep up with him and thus unable to transform into Double.
 * Kamen Rider OOO: Five of the Purple Core Medals enter Eiji's body, destroying any desire that Eiji has left.
 * Kamen Rider Fourze: Meteor kills Gentaro as a part of a deal with the Aries Zodiarts in order to revive his friend Jiro.
 * Kamen Rider Wizard: Haruto loses his ability to use magic due to Legion entering his Underworld and destroying WizarDragon.
 * Kamen Rider Gaim: Kouta is heavily injured and knocked out in a battle with Demushu.
 * Kamen Rider Drive: Shinnosuke is killed by a blast from Freeze, who had just attained his Super Evolution.
 * Kamen Rider Ghost: Takeru loses his life after the Ore Ghost Eyecon is shattered.
 * Kamen Rider Ex-Aid: After reprogramming Parado, Emu loses the Genius Gamer M abilities, which are needed for the Hyper Muteki Gashat to work.
 * Kamen Rider Build: After Evolto separates himself from Sento, Sento regains all of his memories as Takumi Katsuragi, but also loses his new memories as Sento.
 * Halfway through the show, new kinds of monsters are introduced, usually a higher-up of the previous monsters or attained through a different source of evolution.
 * Kamen Rider Double didn't introduce any new monsters during the series' run but the summer movie did introduce Dopants that are created through  the T2 Gaia Memories ability transform anyone with the right compatibility without the use of a Living Connector.
 * Kamen Rider OOO had Giru the Kyoryu Greeed and its Yummies which are created through the use of objects, although they appeared in OOO's Movie War they would make their series appearance through Kiyoto Maki and Eiji Hino who briefly became an alternate Kyoryu Greeed.
 * Kamen Rider Fourze had the Horoscopes.
 * Kamen Rider Wizard didn't have any sort of new monster, but rather, it had their leader and one of his generals be revealed to be large exceptions to how Phantoms are born.
 * Kamen Rider Gaim had the Over Lord Inves.
 * Kamen Rider Drive had the Fusion Roidmudes and eventually the Super Evolution State.
 * Kamen Rider Ghost had the Gamma Superior, the Gamma Ultima, and finally the Gammaizers.
 * Kamen Rider Ex-Aid had the Collabos Bugsters, as well as various Bugsters returning with a higher Level.
 * Kamen Rider Build introduced Hazard versions of various Smash.
 * Beside two main Riders, more Riders are introduced in the series since the appearance of Supporting Riders (Kamen Rider Proto-Birth) in Kamen Rider OOO.
 * Kamen Rider Wizard: Aside from Wizard & Beast, there is also Wiseman & 3 different Kamen Rider Mages.
 * Kamen Rider Gaim: Aside from Gaim & Baron, there is also Ryugen (Yomi), Zangetsu, Gridon, Kurokage, Bravo, Knuckle, Jam, the Kurokage Troopers, Zangetsu Shin, Duke, Sigurd, & Marika.
 * Kamen Rider Drive: Aside from Drive & Mach, there is also Chaser, Gold Drive, & Jun.
 * Kamen Rider Ghost: Aside from Ghost & Specter, there is also Necrom, Dark Necrom P and Dark Ghost.
 * Kamen Rider Ex-Aid: Aside from Ex-Aid & Brave, there is also Snipe, Lazer, Genm, Para-DX, Poppy, and Cronus.
 * Kamen Rider Build: Aside from Build & Cross-Z, there is also Grease, Rogue, Evol, and MadRogue.
 * Each series has a white-colored Rider (with the exception of Kamen Rider Ex-Aid, (though Genm, referred as the Black Ex-Aid though he later assumes a form that is white in color and plays a similar role) and Kamen Rider Build), specially referred to as white.
 * Kamen Rider Wizard: White Wizard (Kamen Rider Wiseman)
 * Kamen Rider Gaim: White Armored Rider (Kamen Rider Zangetsu)
 * Kamen Rider Drive: White Kamen Rider (Kamen Rider Mach)
 * Kamen Rider Ghost is a special case as Kamen Rider Necrom is only referred to as the "White Kamen Rider" in an episode title.
 * With the exception of Build, each series has a character who is the closest friend of the protagonist and a relative of the series' white Rider.
 * Kamen Rider Wizard: Koyomi Fueki
 * Kamen Rider Gaim: Mitsuzane Kureshima
 * Kamen Rider Drive: Kiriko Shijima
 * Kamen Rider Ghost is a special case as although there is a white Rider, none of the protagonist's closest friends are related to him, instead the Rider is related to one of the main villains of the series itself.
 * Though Alain is technically related to one of the protagonist's closest friends by some connection, they are not blood relatives unlike as seen in the previous seasons.
 * Kamen Rider Ex-Aid is yet another special case, as Poppy Pipopapo is only indirectly related to the season's white-accented Kamen Rider (Genm Level X) through her connection with said Rider's mother.
 * Each series has a mad and treacherous scientist who dedicated his life to research the series' monsters, and can transform into a Kamen Rider.
 * Kamen Rider Wizard: Sou Fueki (Kamen Rider Wiseman)
 * Kamen Rider Gaim: Ryoma Sengoku (Kamen Rider Duke)
 * Kamen Rider Drive: Tenjuro Banno (Kamen Rider Gold Drive)
 * Kamen Rider Ghost is a special case as while Igor is referred to as a mad scientist who researches the Gamma, he only transforms into a Kamen Rider-like monster (Gamma Superior Perfect). There is also Edith, a Gamma scientist, who secretly betrayed the Gamma in order to aid the Kamen Riders, and at one point transforms into Kamen Rider Dark Ghost.
 * Kamen Rider Ex-Aid: Kuroto Dan (Kamen Rider Genm), though his role leans slightly more towards a "Game Master" than an actual scientist. This role is later assumed by Masamune Dan, the true mastermind of the series.
 * Kamen Rider Build: In an unusual case, Takumi Katsuragi, an obsessive designer of nearly all technological tools of conflict in Build, while not being portrayed as an active Kamen Rider, is in fact Sento Kiryu, Kamen Rider Build himself.
 * Each series has a red-colored villain general who can use heat power and become stronger when defeated. Up to Drive, and also later in Build, their role and importance gradually increase after each series.
 * Kamen Rider Wizard: Phoenix (He was defeated by the main Rider's Super Form)
 * Kamen Rider Gaim: Demushu (He was defeated by the main Rider's Final Form)
 * Kamen Rider Drive: Heart (He is the leading general and is stronger than the main Rider's Final Form)
 * Kamen Rider Ghost: While there is no recurring red villain general in the show, Gammaizer Fire does share some trends with this trope, as it has pyrokinesis and can resurrect itself after each defeat. Adel also stated in Episode 33 that the Gammaizers become more powerful after every defeat.
 * Kamen Rider Ex-Aid: Initially, there was no recurring red villain general in the show. Graphite, however, later obtained a red form, making him fit for this trope. As well, he made a unique return from death prior to obtaining his red form, alluding to this trope's knack for becoming stronger when defeated.
 * Kamen Rider Build: Evolto (He is revealed to be the true villain of the show, having already begun his schemes since before the start of the series.)
 * Each series has a calm and calculative, but psychotic green-colored villain general. In contrast, their role and importance gradually decrease after each series up to Drive.
 * Kamen Rider Wizard: Gremlin, the manipulative usurper who was one of Wizard's final opponents.
 * Kamen Rider Gaim: Redyue, a treacherous Over Lord Inves who was a secondary villain.
 * Kamen Rider Drive: Brain, the comic relief of the Roidmude generals.
 * Kamen Rider Ghost: While there is no recurring green villain general in the show, Alain, the regular villain general since the beginning, can transform into a Kamen Rider with a green default form. He has gradually changed from a calculative villain to a fully heroic Kamen Rider. In contrast, Adel has become the more psychotic and calculative villain general in Alain's place, although he does not wear green.
 * Kamen Rider Ex-Aid: While Graphite was initially green, he doesn't fit into this trope. Instead, this role is fulfilled by Masamune Dan, who can transform into a green Kamen Rider.
 * Kamen Rider Build: While Nariaki Utsumi fulfills the qualities of being calm and calculative, he is rarely associated with the color green, instead transforming into a white and purple-accented Kamen Rider.
 * Each series' endgame has a character who defeats the main villain instead of the Primary Rider.
 * Kamen Rider Wizard: Gremlin
 * Kamen Rider Gaim: Redyue and Kaito Kumon
 * Kamen Rider Drive: Go Shijima
 * Kamen Rider Ghost broke this trend, as Ghost was the one who defeated all major antagonists in the series.
 * Kamen Rider Ex-Aid: Masamune Dan is a self-inflicted example of this, as he kills himself.
 * Kamen Rider Build once again breaks this trend, with Sento defeating Evolto.
 * Between their Main Forms and their Super Forms, all main Riders also have a set of forms that are upgraded from their base forms. In the toylines, all of these forms have the ability to somewhat interchange.
 * Kamen Rider Wizard: Dragon Styles. One WizarDragon part can be attached to each of the Dragon Styles.
 * Kamen Rider Gaim: Jimber Arms. All of the Jimber Arms share the same Armor Parts, which have four sides. Each side represents a respective Energy Lockseed.
 * Kamen Rider Drive: Type Dead Heat. Its helmet is designed to transform between Drive and Mach, although this is only for accuracy to the Tire Koukan figure series and never happens on-screen. Additionally, Type Dead Heat's tire burns out upon loss of control of the form.
 * Kamen Rider Ghost: Toucon Boost Damashii, which is an upgraded version of Ore Damashii. It can also don any Damashii used by the Ore Transient, as well as the three Damashii that debut for it.
 * Kamen Rider Ex-Aid: Most of Ex-Aid's forms fit this trope: The Level 3, 4, and 5 forms are all theoretically interchangeable between Riders; Level 5 in particular being an extra strong form that can have Rider-specific modes or its fully-armored single-Rider mode; and Mighty Brothers XX is a direct upgrade to Mighty Action X that can split into two Riders.
 * Kamen Rider Build: RabbitTank Sparkling is a direct upgrade to RabbitTank Form. While it features no unique transformation gimmicks, Build's true Super Forms, RabbitRabbit Form and TankTank Form, are armor attachments on top of RabbitTank Hazard Form.
 * Besides the normal humanoid monsters, the main Riders also occasionally have to fight against giant CGI monsters. This was first featured in Kamen Rider Hibiki.
 * Kamen Rider Wizard: Inner Phantoms
 * Kamen Rider Gaim: Evolved Inves
 * Kamen Rider Drive: Giant Roidmudes
 * Kamen Rider Ghost: Giant Gamma & Gundari
 * Kamen Rider Ex-Aid: Bugster Union
 * Kamen Rider Build: Guardian (Union State)
 * Unlike the first three series in the Phase 2 era where the monster-of-the-week is directly created by the villain generals, the main villain groups since Wizard are loose and not well-organized.
 * Kamen Rider Wizard: All Phantoms, including the generals, were created at the same time.
 * Kamen Rider Gaim: Most Inves, including the generals, were randomly mutated from creatures eating the fruit of Helheim.
 * Kamen Rider Drive: All Roidmudes, including the generals, were created at the same time.
 * Kamen Rider Ghost: Most of the Gamma were randomly converted from humans whose souls were stolen into the Gamma world. It is later revealed that the Gamma were once humans from a village tribe in the past; the earliest Gamma (the Gamma royal family among others) being created at the same time.
 * Kamen Rider Ex-Aid: While all Bugsters are parts of the game Kamen Rider Chronicle, they don't have a real leader, and only act as how they were programmed.
 * Kamen Rider Build: Smash are nearly mindless in their destructive rampages, while the Faust that created them endures infighting at the hands of Blood Stalk.
 * Unlike Double and Fourze who don't have any weapons in their primary forms or OOO whose Medajalibur was received as a present by the Kougami Foundation, all of the main Riders have a default sidearm.
 * Kamen Rider Wizard: WizarSwordGun
 * Kamen Rider Gaim: Musou Saber
 * Kamen Rider Drive: Handle-Ken & Door-Ju
 * Kamen Rider Ghost: Gan Gun Saber
 * Kamen Rider Ex-Aid: Gashacon Breaker
 * Kamen Rider Build: Drill Crusher
 * Kamen Rider Zi-O: Zikan Girade
 * While some advanced weapons in the previous three series (Double's Prism Bicker, OOO's Taja Spinner, and Fourze's Cosmic Module Barizun Sword) can be loaded with different Collectible Devices to unleash different effects, the ability to use Collectible Devices together with the main Rider's primary weapon has become a standard since Wizard. Ghost is the only season to break this trend, although the series still has weapons that utilize collectible devices (Sunglasseslasher, Gan Gun Catcher).
 * Unlike Double, OOO, and Fourze whose default Main Forms consist of cold/neutral colors, all of the main Riders since Wizard have warm colors for their default Main Forms.
 * Kamen Rider Wizard: Red
 * Kamen Rider Gaim: Orange
 * Kamen Rider Drive: Red
 * Kamen Rider Ghost: Orange
 * Kamen Rider Ex-Aid: Pink
 * Kamen Rider Build is a special case, as Build's default form utilizes both warm and cool colors (red and blue).
 * Kamen Rider Zi-O breaks this trend, with Zi-O being predominantly black and white with pink accents.
 * There are Rider Troops for each series, with the exception of Build.
 * Kamen Rider Wizard: Kamen Rider Mage
 * Kamen Rider Gaim: Kurokage Troopers
 * Kamen Rider Drive: Mass Production Model Mach
 * Kamen Rider Ghost: Kamen Rider Necroms
 * Kamen Rider Ex-Aid: Ride-Players
 * Each series has a transformation belt that is utilized by at least two in-series Riders.
 * Kamen Rider Wizard: Mage's Belt (Orange Mage, Blue Mage, & Green Mage)
 * Kamen Rider Gaim: Sengoku Driver (Armored Riders) & Genesis Driver (New Generation Riders)
 * Kamen Rider Drive: Mach Driver Honoh (Mach, Chaser, & Jun)
 * Kamen Rider Ghost: Ghost Driver (Ghost & Specter)
 * Kamen Rider Ex-Aid: Gamer Driver (Ex-Aid, Brave, Snipe, Lazer, Genm and later Para-DX) & Buggle Driver II (Poppy & Cronus)
 * Kamen Rider Build: Build Driver (Build & Cross-Z), Sclash Driver (Cross-Z Charge, Grease and Rogue), & Evol-Driver (Evol and MadRogue)
 * Kamen Rider Zi-O: Ziku-Driver (Zi-O and Geiz)
 * The series will usually take a secondary rider out of the action for various reasons and various lengths or even fights with the villains for multiple episodes.
 * Kamen Rider Wizard: Nitoh's Beast Driver is destroyed near the end of Wizard, though he temporarily joined the villains for one episode.
 * Kamen Rider Gaim: Takatora nearly gets killed by Ryoma and his Genesis Driver is taken from him by Mitsuzane. After hanging with Rosyuo for a bit, he comes back as Kamen Rider Zangetsu, but his Sengoku Driver is destroyed and is knocked into a coma by Mitsuzane until the end of the show. He was also an antagonist for the majority of the show.
 * Kamen Rider Drive: Go feigns an alliance to the Roidmudes in order to get closer to them and retrieve Banno. By the end of the show, both Chase and Go are killed and incapacitated respectively in the final battle.
 * Kamen Rider Ghost: Makoto at one point is brainwashed by the Necrom Eyecon and in another point, his body is destroyed, leaving him out of the show for a couple of episodes.
 * Kamen Rider Ex-Aid: Hiiro Kagami is briefly incapacitated due to strain placed on his body by his Level 50 form. He later briefly allies himself with Masamune Dan in a bid to restore his girlfriend, though he returns to the heroes' side after a while.
 * Kamen Rider Build: Ryuga Banjo is possessed by Evolto for two episodes due to him having a piece of Evolto's DNA inside of him.
 * The leader of the main villain group is usually betrayed and sometimes, if not usually, killed by one of their subordinates.
 * Kamen Rider Wizard: Sou Fueki/Wiseman was killed by Sora Takigawa/Gremlin, who wanted the Philosopher's Stone.
 * Kamen Rider Gaim: Rosyuo was betrayed and killed by Redyue in search of the Golden Fruit.
 * Kamen Rider Drive: Heart and Medic betray Tenjuro Banno after his true plans were revealed.
 * Kamen Rider Ghost: Adel, wanting to take over the throne as the Gamma Emperor, first "assassinates" his father Adonis, framing his brother Alain for it. Later, he truly kills Adonis once and for all while Adonis is in his physical form. Later, Adel himself is betrayed by the Gammaizers, who absorbed the Great Eye for themselves.
 * Kamen Rider Ex-Aid: Parado severs ties with Kuroto Dan once the latter states the Bugsters are pawns for his schemes. He eventually murders Kuroto after his defeat by the main protagonists.
 * Kamen Rider Build has two cases:
 * Soichi Isurugi (possessed by Evolto) betrays Gentoku Himuro and defects to Hokuto when the war for the Pandora Box broke out. In reality, he is also aligned with the Seito government, later furthering on his own agenda.
 * Majority of Build's former enemies team-up with him to battle Evolto.
 * The plot of each season's summer movie usually involves an alternate world or timeline being shown in contrast with the present world or timeline, somewhat harking back to the early Heisei Phase 1 summer movies of Ryuki, 555, Blade and Kabuto, which feature alternate endings to the main series storyline.
 * Kamen Rider Wizard: Kamen Rider Wizard in Magic Land had Haruto and Koyomi end up in Magic Land.
 * Kamen Rider Gaim: In Kamen Rider Gaim: Great Soccer Battle! Golden Fruits Cup!, Kouta finds himself in an alternate dream world created by Lapis.
 * Kamen Rider Drive: In Kamen Rider Drive: Surprise Future, a dystopian future from the year 2035 is shown.
 * Kamen Rider Ghost: Kamen Rider Ghost: The 100 Eyecons and Ghost's Fateful Moment had Takeru and his friends end up in the Island of Eyecons.
 * Kamen Rider Ex-Aid In Kamen Rider Ex-Aid: True Ending, Emu has to travel to the Game World through Virtual Reality midway through the movie.
 * Kamen Rider Build breaks this trend, as Kamen Rider Build: Be The One takes place between episode 45 and 46, tied in to the events of the series proper.
 * Each series includes a golden evil Kamen Rider:
 * Kamen Rider Wizard: Kamen Rider Sorcerer
 * Kamen Rider Gaim: Kamen Rider Mars
 * Kamen Rider Drive: Kamen Rider Gold Drive
 * Kamen Rider Ghost: Kamen Rider Extremer
 * Kamen Rider Ex-Aid: Gamedeus Cronus
 * Kamen Rider Build: Kamen Rider Evol
 * Kamen Rider Zi-O: Ohma Zi-O
 * With the exception of Gaim's Kiwami Arms and Ex-Aid's Muteki Gamer, all protagonist Riders lose their final form at the end of the series:
 * Kamen Rider Wizard: Haruto gave his Infinity Ring to his A.R. counterpart.
 * Compared to the others, however, he regains said form after obtaining another Infinity Ring, that being from his Bujin counterpart.
 * Kamen Rider Drive: Mr. Belt locked himself and all Drive equipment underground.
 * Kamen Rider Ghost: The Mugen Eyecon faded away after Takeru used it to defeat the giant Great Eyezer.
 * However, Takeru would somehow regain Mugen Damashii by the events of Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider.
 * Kamen Rider Build: The Genius Bottle is drained of its essence during the final battle against Evolto, prompting Sento to resort into using RabbitRabbit, RabbitTank Sparkling, RabbitTank, and finally, RabbitDragon forms.
 * The main Rider usually uses a disproportionately high number of collectible transformation devices as compared to the other Riders.
 * Kamen Rider Gaim: Gaim has altogether used a total of 18 Lockseeds (counting borrowed, stageshow-exclusive and Legend Rider), as compared to the other Riders who at most, have not used more than 10 different Lockseeds.
 * Kamen Rider Drive: Drive possesses a total of 31 Shift Cars in his arsenal (counting Tire Exchange Shift Cars which were not used in battle), as compared to the Signal Bikes' small number of 7.
 * Kamen Rider Ghost: Out of the 15 heroic Ghost Eyecons, Ghost has 10, while Specter has 3 and Necrom only has 2.
 * Kamen Rider Ex-Aid: In a slightly less extreme case, Ex-Aid makes use of a total of 15 Gashats across all episodes, movies, and specials, with Brave in second place at 8, and Snipe in third at 6 (7 counting his appearance as Cronus).
 * Kamen Rider Build: There are a total of 60 regular Fullbottles that Build can potentially use for his Best Match forms, plus 3 other unique Bottles for his power-up forms, while all other Riders and Rider-like warriors have only used standalone Fullbottles or variants of those (Sclashjellies, Gears, Evolbottles etc.)
 * Each season usually has the third main Rider originally start off as good during or before the start of the series, then become evil for a period of time before finally redeeming themselves and going on the side of good again. Their Rider forms usually have either purple or green accents (or both in Ryugen's case).
 * Kamen Rider Gaim: Mitsuzane Kureshima, originally a friend of Kouta, later joins and eventually takes over Yggdrasill, betraying everyone around him. At the end of the series, he redeems himself for the sins he had committed.
 * Kamen Rider Drive: Chase was originally Protodrive, the warrior who fought the Roidmudes during the Global Freeze, before being brainwashed into becoming Mashin Chaser. Later, he regains his memories and becomes Kamen Rider Chaser.
 * Kamen Rider Ghost: It is not known if Alain was originally good at first, but he grew to believe that his world was perfect and that the human world was flawed. Later, after the death of his father Adonis, Alain finally accepts that his world is not perfect, and joins the side of good as Kamen Rider Necrom.
 * Kamen Rider Ex-Aid: Taiga Hanaya was originally a kind doctor who was part of CR. However, the effects of the Proto Gashats had affected his mind and body, turning him into a somewhat anti-heroic Rider, though he later comes to respect the other Kamen Riders over the course of their fight against the Bugsters. This also applies to Kuroto Dan, who is first introduced as a villain for the first half of the season, until he joins with the heroes when his father took over Kamen Rider Chronicle.
 * Kamen Rider Build: Kazumi Sawatari started out as hostile towards the protagonists as he was the representative Rider whose government opposing Touto.

 * Kamen Rider Build: Evolto, after absorbing the black-colored Lost Panel with the 10 Lost Bottles, can warp to other worlds via wormholes.
 * Each season has a spring movie which focuses more heavily on the Kamen Riders rather than other tokusatsu seasons, as compared to the first two Super Hero Taisen films. Incidentally, Kamen Rider 1 plays a significant role in each of these films.
 * Kamen Rider Gaim: In Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai, Rider 1 leads the Showa Riders, wanting to battle the Heisei Riders.
 * Kamen Rider Drive: In , history is changed because of Rider 1 and 2's defeat at the hands of Rider 3.

 * Kamen Rider Build: Cross-Z Magma's evolution from Cross-Z's default form seems to be a nod to Build's RabbitTank Sparkling, which itself is an evolution from Build's default RabbitTank Form. Later, Grease Blizzard would also utilize the same concept, with both Cross-Z Magma and Grease Blizzard using similar knuckle-like devices to transform.
 * The primary Riders' final form no longer has its own designated weapon. Instead, it uses the weapon used by the upgrade/super form.

 * Kamen Rider Ghost: Makoto Fukami (Kamen Rider Specter) was previously friends with Alain (Kamen Rider Necrom) in the Gamma World. After Makoto joined the Daitenku Temple to fight the Gamma, Alain took it himself to become Kamen Rider Necrom and fought against his former friend as a means to forcibly bring him back to the Gamma World. Their clashing ended after Alain's banishment and he eventually rekindled his friendship with Makoto.

 * Kamen Rider Build: Ryuga Banjo (Kamen Rider Cross-Z) and Kazumi Sawatari (Kamen Rider Grease) didn't get along at first and started off as enemies during the Touto-Hokuto war. After Kazumi joined Team Build to fight against Seito, the two soon became friends. Kazumi is the only rider to call Ryuga Banjo by his first name while everyone else calls him by his last name.

Kamen Rider in the Heisei Phase 2 era
The crossover between a Kamen Riders from a different series was all started from the Kamen Rider Den-O & Kiva: Climax Deka in Phase 1, as a starter up for the next Rider crossover within Phase 2, starting from Movie War series.

Advertisements throughout the months of May, June, and July 2009 built up to the debut of Kamen Rider W who was introduced as the eleventh addition of the Heisei Era, first appearing at the 10th Anniversary Project MASKED RIDER LIVE & SHOW event, and was featured in Kamen Rider Decade: All Riders vs. Dai-Shocker. The title characters star as detectives investigating crime waves about kaijin known as Dopants in the fictional city of Futo. Like much of the previous entries of the Heisei Era, the titular Rider, Kamen Rider Double, can transform into multiple forms, using devices shaped like USB hard drives called Gaia Memories. The Dopants that they fight are really people that use unrefined Gaia Memories for their own purposes. Double is also the first Kamen Rider to transform from two people at once. This series is also the first instance where the show airs on the same day it's predecessor (in this case, Decade) airs it's finale. The series premiered on September 6, 2009. Continuing into 2010 with Kamen Rider × Kamen Rider W & Decade: Movie War 2010, W ran for a full year from September 2009 to September 2010, instead of January to January. Also in 2010 were the second, third, and fourth films of the Cho-Den-O Series, collectively known as Kamen Rider × Kamen Rider × Kamen Rider The Movie: Cho-Den-O Trilogy. Along with Den-O and Kabuto, it became one of the most successful Heisei Kamen Rider series.

In late 2010, Kamen Rider OOO was introduced as the twelfth addition of the Heisei Era Kamen Rider Series. The title character is a world traveler that is pulled into a fight with kaijin called the Greeed that was resurrected from a 800-year sleep to find themselves incomplete by such a Greeed, reduced to the status of a forearm, who gives him the means to transform into Kamen Rider OOO. Like Kamen Riders BLACK RX to Agito, and Den-O to Double, Kamen Rider OOO can change forms, but unlike the others, OOO can transform using three Core Medals, special coin-based artifacts based on animals that make up a Greeed's ability to stay alive without falling apart. There are nine Core Medals for each set, three each designated for Head, Arms, or Legs. As so far, OOO has the most transformations in Kamen Rider history, having able to use a possible 126 different combinations of Core Medals.

The year 2011 celebrated the 40th anniversary of the franchise. The festivities included the Kamen Rider Girls idol group, the film OOO, Den-O, All Riders: Let's Go Kamen Rider, released on April 1, 2011, and OOO's successor Kamen Rider Fourze, which references the previous heroes in its characters' names and within the plot. OOO, Den-O, All Riders: Let's Go Kamen Rider was the first starter up of the Taisen movie series, which was included Super Sentai's Akaranger, Other heroes like Zuban, original Kikaiders and original Inazuman, resulting a development of the first Super Hero Taisen crossover film titled , which was released in 2012, featuring the main heroes from all Kamen Rider and Super Sentai series produced until then, then becomes expanded with the other heroes like Metal Heroes (particularly Space Sheriffs) and the other heroes like new Inazuman from Movie War Ultimatum, sans in Gaim and Drive's own spring movies, which focused on all Kamen Riders with less Super Sentai team that focused on the sophomore and the current ones.

Number Theory?
A fan theory about Phase 2 is series seems to follow an increasing numbered theme, although this gradually became less obvious with each season:
 * Kamen Rider Double: A Kamen Rider formed from TWO people.
 * Kamen Rider OOO: A Kamen Rider uses THREE Medals to transform.
 * Kamen Rider Fourze: A Kamen Rider with weapons on his FOUR limbs. Also, the forty anniversary of the series, with the word "FOUR" in its name.
 * Kamen Rider Wizard: A Kamen Rider uses magic via FIVE-fingered hand-shaped scanners.
 * Kamen Rider Gaim: Lockseeds are shaped like number "SIX".
 * Kamen Rider Drive: The shape of part of the Katagana ve (ブ) of the title logo shaped like the number "SEVEN".
 * Kamen Rider Ghost: The Infinity symbol ∞, which looks like a horizontal number EIGHT, appears in many ways in the series (Sunglasseslasher/Deep Slasher's slots, Mugen Damashii, etc.)

However, this theory was ended by Toei producer Takahito Omori during Kamen Rider Ex-Aid's run. According to Takahito, the key number of Ex-Aid is number TEN, which conflicts with this theory. It marks the first time Toei has responded to a Phase 2 fan theory and killed it.
