|This article is about a/an group of monstrous Kamen Riders in Kamen Rider Zi-O.|
Another Riders (アナザーライダー Anazā Raidā) are a group of monstrous Kamen Riders whose powers are derived from their original counterparts.
Another Riders are created when an individual comes into contact with an Anotherwatch, that has absorbed the power of a Kamen Rider, and has the watch inserted into their bodies. These Anotherwatches can only be created by a Time Jacker, who can then insert the Ridewatch into either themselves or a host of their choosing. The resulting transformation is a monstrous aberration that slightly matches the Rider in appearance, though only varying in dissimilarity. More recent users, however, seem to have some form of control over their Another Rider powers and can transform into their monster forms at will.
Once an Anotherwatch is created, the respective Kamen Rider will lose all of their powers, memories, mortal enemies, as well as their "history", which drastically alters the timeline. Typically, there is an incubation period where the creation of the Another Rider will not immediately siphon all of their original counterpart's powers, thus leaving room for a brief fight if the two manage to encounter each other. Several Riders such as Build, Cross-Z, Ex-Aid, Ghost, Specter, and Zero-One have experienced this.
The original Rider themselves can regain their memories (and to some extent, their powers) if the Another Rider was defeated by not using their respective Ridewatches. Due to a fracture in the space-time continuum, this rule was eventually nullified.
Another Riders have their creation year on their bodies along with their names. However, that number can be interfered if the host is a former Rider from an entirely different era, than the Rider the Another Rider is based off of. For example, Kuroto Dan is from 2016's Ex-Aid, but was turned into Another OOO, who originated in 2010. This caused the 2010 that was written on him to look similar to 2016, which had initially influenced Geiz Myokoin to use the Genm Ridewatch. This rule does not apply on the Riders that come after Zi-O, i.e. Shinobi, Quiz, Kikai, and Zero-One.
Because the Another Riders have powers tied to space-time, they can only be defeated so long as the Rider has at least a small portion (or copy) of the original Rider. This can be achieved by:
- The original Rider themselves provided they are serious about destroying the Another Rider.
- Rider Armor/Futurering Form based on the Rider
- Decade/Diend using a Rider Card to become/summon the Rider
- Zi-O and Geiz using a form equipped with several Rider powers, which includes GrandZi-O, GeizMajesty, and Ohma Zi-O.
- Zi-O, Geiz, and Woz using forms that can manipulate time in some way, allowing them to bypass Ridewatch restrictions. . Zi-O Trinity can be used to specifically defeat ones equipped with multiple Rider powers.
Defeating them through any other means will only incapacitate the host momentarily, allowing them a chance to turn once again. During this time, the original Riders' powers and memories will return temporarily, allowing them to interact with Sougo and Geiz properly and give them their respective Ridewatches, allowing Zi-O (or Geiz) to travel back in time to when the Another Rider was created and defeat them permanently using the newly acquired Ridewatch. The side-effect of this, however, is that once the Another Rider is destroyed, the changes made during the altered timeline also become permanent. For the Future Riders, this period of time allows White Woz to create the appropriate Miridewatch needed to defeat the Another Rider, due to the Future Riders not existing during the present day.
As with the difficulties and restrictions tied with creating Ridewatches of Riders from alternate or erased/alternate continuities, the same can be said for Another Ridewatches where some Another Riders were unable to be created until the Time Jackers bypassed the restrictions and Swartz merged the multiverse.
- Tsukasa Kadoya/Kamen Rider Decade (Rider): An Another Decade was originally not possible from the start of the series due to Tsukasa originating from an alternate reality. However as Swartz slowly began merging the worlds together, it cost Tsukasa this immunity and ultimately his powers, creating Another Decade.
- Dark Shinji/Kamen Rider Ryuga: Because the Mirror World was inaccessible by normal means, the Time Jackers weren't able to initially make an Another Ryuga until Dark Shinji willingly let them. This method also applies to all of the Riders that exist in Kamen Rider Ryuki, including the Decade-exclusive Kamen Rider Abyss. However with the merging of all the realities, these Riders most likely lost their immunity.
- Kamen Rider Ginga: Ginga's origins are completely unknown, which means an Another Ginga is likely not possible. However with Swartz merging all the realities, Ginga most likely lost this immunity. To date, an Another Ginga has not made an appearance in any related media.
Because Ridewatches essentially steal the Rider's powers and history, both the Another Rider and Kamen Rider cannot simultaneously exist, yet there have been special cases where this rule was superseded.
- People such as Singularity Points are protected from temporal changes regarding the past and do not lose their memories and Rider powers if they ever had any. This includes Ryotaro Nogami and every single Rider in Kamen Rider Den-O.
- In Kamen Rider Heisei Generations FOREVER, Kamen Riders Kuuga and Double were able to exist while Another Kuuga and Double were still around. This is due to all of the Riders present at the scene being manifestations from fiction and not the actual Riders themselves.
- Due to Kouta Kazuraba's status as a god, Another Gaim's creation preserves his divine being, but only temporarily. The timeline alteration and God Kouta's erasure from existence become imminent once Another Gaim is defeated.
- Mondo Douan and Another Quiz were able to co-exist because the Mondo that appeared in 2019 alongside Another Quiz was taken from a moment before his powers were corrupted. By this logic, most Kamen Riders may continue to exist if a version of them before their powers were taken was brought to a point where an Another Rider of them exists.
- Rento Makina is able to exist as a Kamen Rider in 2121 despite the existence Another Kikai in 2019 because he is nothing but a figment of Sougo's imagination being brought to life and being permeated into history itself. These creations cannot be altered in any way.
- Shinji Kido and the rest of the Ryuki Riders were still able to transform in 2019 despite the existence of Another Ryuki for unknown reasons.
- If an Another Rider was not created within a year of their original counterpart's debut, it will not erase the original's existence. Starting from the creation of Another Zi-O, the following Another Riders (with the exception of Another Riders based on Kamen Riders from the future) are created in 2019 rather than the year of their corresponding Kamen Rider's debut. This is mostly due to a currently unexplained space-time distortion.
- Tsukasa Kadoya was still able to access his Rider powers despite Swartz stealing them to become Another Decade. This is because Swartz was only able to steal half of Tsukasa's powers, with the other half being used to create the Decade Ridewatch, which Tsukasa regained.
- Unlike the previous Another Riders created in the same year as their counterparts debuted, Zero-One's supporting Riders (Vulcan, Valkyrie, Jin & Horobi) still exist in the alternate timeline and Zero-One's enemies (Magia) were not erased from existence.
The first known Another Rider, Another Build, was created in 2017, transforming from a basketball player. Originally destined to die, he was saved by Heure, who provided him with the Another Build Ridewatch.
The second Another Rider, Another Ex-Aid, was created in 2016. He was a father who's son was hospitalized for an unknown reason. Offering to save his son, Ora provided him with the Another Ex-Aid Ridewatch.
The third Another Rider, Another Faiz was created in 2003. Ryuichi Sakuma, a student who felt guilty about his girlfriend's death, was offered the Another Faiz Ridewatch by Ora, and used it's power in order to save his deceased girlfriend. This power, however, eventually waned as it started to weaken in 2011. Made desperate by the fact his power was fading away, he was approached by another Time Jacker, Swartz, and was given the Another Fourze Ridewatch, becoming the fourth Another Rider, Another Fourze.
The fifth Another Rider, Another Wizard was created in 2012 when Hayase, a stage hand on a rundown magic theatre is found by Heure. To save the theatre, Hayase formed a contract with the Time Jacker and achieved magical power. At first, Hayase only uses his newfound magical power to perform magic shows that returns the theatre to its former glory, but after knowing that the theatre is going to be closed down anyways, he went berserk and attacks his show companions.
The sixth Another Rider, Another OOO was created in 2010, when Kuroto trying to prove that his dad is wrong as he thinks that he is immortal with his godlike talent. Heure made a contract with Kuroto Dan to become Another OOO. Using his authority, Kuroto established the Foundation in 2016 after the death of his father, and the Foundation soon grew into a mega corporation within two years. As an Another Rider, he uses cell medals to summon Waste Yummies to subjugate the people. Kuroto holds a press conference and declares that Dan Foundation will rule as a sovereign nation independent from Japan, with all of their properties becoming their own national territory where Japan's own laws become null and void.
The seventh Another Rider, Another Gaim was created in 2013, when Asura was a member of Team Baron who was expelled by Kaito and his peers. While lashing out at his former leader, Swartz freezes the time and transforms Asura into Another Gaim. Using his newfound ability, Asura expels Kaito and those who dare to oppose him into Helheim, while also taking over Team Baron's leadership.
Time Jacker Tid created the eighth Another Rider, Another Double (2009 ver.) to capture Ataru's big brother, Shingo Hisanaga before Another Double forcibly turns Ataru into the ninth Another Rider, Another Den-O (2007 ver.). Tid then raids the mummified tomb of Riku, the original Kamen Rider Kuuga. Announcing his plans to end the legacy of the Heisei Riders, he seals Kuuga's powers into an Another Ridewatch and transform himself to the tenth Another Rider, Another Kuuga (2000 ver.). After his first defeat at the hands of Build and Zi-O (assuming Kuuga Armor), Tid uses it again and combines himself with Shingo to create the eleventh Another Rider, Another Ultimate Kuuga but was later killed at the hands of all the Heisei Riders.
The twelth Another Rider, Another Ghost was created in 2015, when Makimura was on duty when his sister, Maki gave him a Bento box. Just after Maki left, several steel beams suddenly fell from above, and were about to kill Mika if Heure didn't appear at the last moment, stopping time. Heure proposes to form a contract with him in order to save Mika and crown Makimura as the new King for the Time Jackers. Out of sheer will alone, Makimura directly rejects Heure’s proposal. Makimura declares that he will not work with an evil person like Heure and that he’ll save Mika with his own power, much to Heure's disappointment and annoyance. Heure decides to let Makimura do as he pleased as he resumes the time. Makimura then pushes Mika away and gets hit by the steel beams instead, fatally wounding him. However, seconds before his death, Heure stops time once more, and forcefully inserts the Another Ghost Ridewatch into Makimura, now a lifeless corpse.
The thirteenth Another Rider, Another Shinobi was created in 2019, when Rentaro, after being beaten by thugs when standing up for a friend, desire strength and Heure imbued him with the Shinobi Anotherwatch, transforming him into his corrupted version of his future self.
The fourteenth Another Rider, Another Quiz was also created in 2019, when Tamotsu Douan hit a dead end with his projects, causing him to abandon his wife and son. When Mondo arrives to 2019 under White Woz's ability, Ora used this opportunity to transform Tamotsu into a twisted version of his son's future alter-ego, Another Quiz. This caused him to attack his fellow researchers and absorb their knowledge, creating a string of disappearance cases.
The fifteenth Another Rider, Another Ryuga was created in 2019. Heure met Dark Shinji thanks to Tsukasa Kadoya's information about the mirror world. Heure learned that Dark Shinji had once been defeated in a Rider War, but as long as the real Shinji Kido exists, Dark Shinji will continue to manifest.
The sixteenth Another Rider, Another Kikai was created in 2019. A unique Another Rider which was created from Sougo Tokiwa's dreams, it manifested in the form of a stick insect-like creature which used organic matter to create a body of its own. Whenever it was defeated, it would hunt for another tree that it could then use as its form. After many defeats from the riders, Another Kikai was taken by Swartz. Its power was forcibly used on Heure for the purpose to take the power of Kikai.
The seventeenth Another Rider, Another Zi-O was created in 2019, when Hiryu Kakogawa want to kill Sougo Tokiwa in a accident in 2009. Before that happen, Hiryu went on a hunting spree against former Another Rider hosts to harvest their Anotherwatches and recreate several Another Riders powers.
The eighteenth Another Rider, Another Ryuki (2002 ver.) is created in 2019 when Tatsuya Kano was given an Anotherwatch by a mysterious individual, revealed to be the new user of Odin deck, and kill innocent victims in order to revive Sara.
The nineteenth Another Rider, Another Blade was created in 2019, when White Woz manipulates Amane Kurihara's emotions, making her attack multiple photo studios and asking the staff about Hajime's whereabouts.
The twentith Another Rider, Another Agito was created in 2019, though it's never revealed whom the identity of the host was. With each person he bites, they are forcibly turned into mutated copy of Another Agito. After Heure stole the powers of Kamen Rider Agito, he fused those powers with Another Agito, transforming it into a copy of it's Kamen Rider couterpart.
The twenty-first Another Rider, Another Hibiki was created in 2019, when Tsutomu Tsuzumiya was a kid, he dreamed of becoming a great Oni like Kamen Rider Hibiki. However on his current year, the dream seemed to be an illusion and Heure forced him to have the power of an Oni and go on a rampage.
The twenty-second Another Rider, Another Kiva was created in 2019, when Yuko Kitajima was arrested and incarcerated for a murder she insists she didn't commit. Ora broke her out by turning her into Another Kiva.
The twenty-third Another Rider, Another Kabuto was created in 2019. Yaguruma receives an Anotherwatch from Heure and is turned into Another Kabuto, with a Worm who has previously mimicked his late partner Kageyama seemingly supporting him.
Another Den-O was also created in 2019, when Ora came and told Takuya that she can make his grudges against Yukihiro go away as he tells Yukihiro Osumi that it's his fault that Takuya's sister is dead, and eventually told Yukihiro to never come back.
The twenty-fourth Another Rider, Another Zi-O II was created in 2019. After a long absence, Hiryu came back again with a new power and he declared to Sougo that he had a new goal, to take what Sougo should have obtained and change the timeline. In addition, he also recreated all previous Another Riders using his new powers.
The twenty-fifth Another Rider, Another Decade was created in 2019. Following Another Zi-O II's defeat, Swartz would utilize a blank Ridewatch to steal Tsukasa Kadoya's powers as Kamen Rider Decade with Kaito's help. He then uses his abilities to send himself, Zi-O and Geiz into an Alternate World to battle A.R. Versions of Four Dark Riders.
The twenty-sixth Another Rider, Another Drive would also be created by Swartz in 2019. Following Swartz's acquisition of the Another Decade Watch, he disbands the Time Jackers. He uses Another Drive to eliminate his former subordinates. It also assumes Ora's appearance.
The twenty-seventh Another Rider, Another Ohma Zi-O, created himself in 2019 by fusing the powers of Kamen Rider Barlckxs and Seven Legendary Riders to battle Zi-O and Ohma Zi-O to rewrite the timeline completely.
The twenty-eighth and twenty-ninth Another Riders, Another Zero-One & Another 1 were created in 2007, erasing the Daybreak Town Accident. Another 1, who was created by stealing the powers of Rider 1 from Zi-O, also evolved into the thirtieth Another Rider, Another New 1.
The thirty first Another Rider, Another Diend, appeared from an alternate timeline in the new Spetember 2018 in order to gain the powers of Kamen Rider Geiz.
Powers and Abilities
- Invulnerability: Another Riders are essentially invincible to anything other than the listed weaknesses below and will re-spawn indefinitely if defeated outside those conditions.
- Ridewatch Ejection: In rare occurrences, it's possible for Another Riders to eject regular Ridewatches based on their corresponding power, or, potentially, of one based on their original Rider form. Instances include Another OOO dropping the Genm Ridewatch after being intercepted by the Taka Watchroid and both Blade and Chalice Ridewatches dropped after the defeat of Another Blade, the latter who absorbed their powers.
- Corresponding Rider power: An Another Rider can be harmed and killed by the Kamen Rider they are derived from. Though their presence would soon cause that Kamen Rider to be erased from history (also if this doesn't seem to apply to future Riders Ridewatch wielded by either Zi-O or Geiz in the form of a Rider Armor. Once an Another Rider is defeated by the corresponding Rider Armor, they are permanently neutralized as their Anotherwatch is destroyed. The same rule is applied to other methods of replicating a Legend Rider's power, like with Decade's Rider Cards.
), their power can be preserved and replicated through the
- This weakness can be fixed by having multiple Another Rider' powers in oneself. As long as the first power is not neutralized, that Another Rider would continue to resurrect even when destroyed by the corresponding Rider Armor. Furthermore, the original Kamen Rider may fail to completely defeat the Another Rider if he isn't serious enough.
- Power Decline: Another Riders' lifespan are limited and would eventually fade away. Overusing their power would accelerate this process, as seen when Another Faiz's power began to fade after 7 years. Their lifespan can be prolonged by taking a new Another Riderwatch, gaining a new Another Rider form from it if said Ridewatch is different.
- Kamen Rider Zi-O:
- Zi-O II: Due to Zi-O II having the power to transcend both space and time, his powers are capable of taking out Another Riders without the required Ridewatch needed to defeat them, regardless of when or where the Another Rider had originated. This method only works against an Another Rider with only one set of Rider powers.
- Zi-OTrinity: Like Zi-O II, Zi-OTrinity can also take out Another Riders without the required Ridewatch needed to defeat them. However, Trinity has the added ability to take out Another Riders who have absorbed several Rider powers, such as Another Blade, who also had Chalice's powers within her. Upon defeating the Another Rider, the Ridewatches of the powers that the Another Rider had absorbed will spawn from the destruction of the Anotherwatch. Although unconfirmed, Zi-OTrinity could have taken out Ryuichi Sakuma, who had absorbed both the powers of Fourze and Faiz.
- Kamen Rider GeizRevive: GeizRevive's power comes from the GeizRevive Ridewatch's ability to compress and speed up time. According to White Woz, the Ridewatch is told to possess the ability to defeat any Another Rider.
- Kamen Rider WozGinga: Like Zi-O II & Trinity, WozGingaFinally was seen to be capable of taking out Another Kiva completely, which can be assumed that the form can take out other Another Riders as well.
List of Another Riders
- Storyboard writer Shoma Muto posted three hypothetical Another Riders he personally designed on Twitter, based on Chalice, Mach, & Cross-Z respectively.
- Following the standard aspects of Another Riders, they seem to also have elements of the respective monsters they fought, and of their counterparts upgrades:
- Another Chalice being obvious as the Joker's transformation device near-perfectly mimics the Undead scanned, but with some design elements leaning towards the Paradoxa Undead and possessing a scythe weapon similar to Wild Chalice's Wild Slasher and said Undead's forearm weapon.
- Another Mach's animal designs referencing the three base forms of most Roidmudes(Bat, Spider, and Cobra), and the armor upgrades from Deadheat and merging with Chaser.
- Another Cross-Z being more monstrous in appearance referencing his altered DNA as a result of Evolto's influence, and design elements of both Cross-Z Magma and Cross-ZEvol forms.
- Following the standard aspects of Another Riders, they seem to also have elements of the respective monsters they fought, and of their counterparts upgrades:
- Another Riders traits of having their names and numbers branded on their form is previously used by Mole Imagin.
- According to the designers, some of the Another Riders have elements from other popular media:
- Another Den-O: Oni Momotaro (Momotaro Jigoku-hen, a Ken Ishikawa manga)
- Another Kiva: Spawn (Spawn)
- Another W: Baron Ashura (Mazinger Z)
- Another Fourze: Radar Button (An Uchuu Tetsujin Kyodain monster)
- Another Ghost: Venom (2018 Venom film)
- Another Ex-Aid: Predator (Predator franchise)
- Another Shinobi: Hattori Hanzō (Shadow Warriors, a 1980 show)
- Another Quiz: Hats in UltraQuiz (A Nippon TV quiz show)
- Another Kikai: Pinocchio (Pinocchio)
- Theme wise the Another Riders are slightly similar to the Negative Syndicates of the 30th Super Sentai GoGo Sentai Boukenger as both are themed after something from their predecessor seasons.
- Another Riders are mostly themed on past Kamen Riders (with the exception of Another Shinobi, Quiz and Kikai, who are based on future Riders). They're also connected to them directly, becoming monsters by receiving the power to become a Kamen Rider.
- The villains and monsters in the Negative Syndicates are themed after past Sentai Mecha and Robo's. (EX. Zukangami of the Dark Shadow is based on Denji Gattai Galaxy Mega from the 21st Super Sentai Denji Sentai Megaranger.) However, their connections to the past Mecha are purely visual and sometimes thematic homages, without actual acknowledgement that they're mimicking them in the story itself.
- The Another Riders use concepts from past Rider season Monsters.
- The Another Riders being humans using twisted versions of a Rider Collectible to transform is similar to the Dopants from Kamen Rider W and the Zodiarts from Kamen Rider Fourze.
- Both monster types are normally defeated by a finisher using the same power source, Maximum Drive and Limit Break, respectively.
- The concept of being created from making a contract with a Time Jacker is similar to the Imagin from Kamen Rider Den-O.
- As each Another Rider is given free rein over their actions, but under the intent to cause destruction, their actions are similar to the Fusion Roidmudes from Kamen Rider Drive.
- The idea that the system the devices stem from can create both Riders and monsters is similar to the Gamma from Kamen Rider Ghost and the Bugsters from Kamen Rider Ex-Aid.
- The more grotesque appearance of the Ridewatches is similar to how Gamma Eyecons were more eyeball-like in design.
- The Another Riders being humans using twisted versions of a Rider Collectible to transform is similar to the Dopants from Kamen Rider W and the Zodiarts from Kamen Rider Fourze.
- Most Another Riders have the name of the Rider they are based on and year that series aired on different parts of their bodies. Later in the series, Another Riders often feature the current year instead.
- The overall characteristics of Another Riders appear to be the opposite of their original Rider counterparts. Such as emotions, traumas and inabilities from the original.
- Another Riders's eyes and mouths were designed to be retractable. Only a few of them has the animation for the movements, Another Build and Another Fourze has shown retracting both of their eyes and mouths, while Another Den-O, Another Kuuga and Another Drive has shown retracting their mouths only.
- Some of the Another Riders hosts were Kamen Riders at least some point in their lives.
- Kuroto Dan (Kamen Rider Genm) is the first to do so as he became Another OOO. Kuroto so far is the only one who turned into an Another Rider foreign from his own series.
- Rentaro Kagura (Kamen Rider Shinobi) followed up and turned into his own Another Shinobi. This is an odd exception as the Rentaro that was turned at the time wasn't yet a Kamen Rider.
- Dark Shinji (Kamen Rider Ryuga) followed up and turned into his own Another Ryuga. Dark Shinji is the first "veteran" Rider to turn into the corrupted version of his own Rider form.
- So Yaguruma (Kamen Rider KickHopper) turned into Another Kabuto. He is the first to simultaneously utilize both of his Another Rider and Kamen Rider powers in battle.
- Paradox Roidmude (Kamen Rider Dark Drive) turned into Another Drive. He is the first monster to become not only a Kamen Rider, but also an Another Rider.
- Daiki Kaito (Kamen Rider Diend) inadvertently transformed into Another Zi-O II against his will when he used the Anotherwatch to undo Tsukasa Kadoya's death.
- Another Riders' forms seem to draw aspects from their bases' more powerful forms:
- Another Zero-One: Design aspects similar to the Upper Body of Zero-One's Shining Hopper Form and MetalCluster Hopper's Locust swarm motif and metal color palette on the fingers,shoulder pads and wings,as well as Ark's connection with these forms.
- Another Zi-O (II): Foresight, armor design, dual wielding like Kamen Rider Zi-O II/Summoning Riders to fight on his behalf like GrandZi-O, and Ohma Zi-O's shoulder pads.
- Another Build: A mix of RabbitTank Hazard's and RabbitTank Sparkling's design aesthetics.
- Another Ex-Aid: Hyper Muteki's "hair" and Drago Knight Hunter Z's leitmotif.

- Another Decade: Decade Complete Form's head and leg design and Violent Emotion's color and face.
- Another Diend: Diend Complete Form's leg design and cyan stripes on his chest.
- Another Kiva: Design elements from Kiva's Emperor Form, lack of the Hell’s Gate leg restraint, and the ability to use all 3 Arm Monsters weapons like DoGaBaKi(Emperor) form.

- Another Kuuga: A potential force of destruction and an ability to grow more powerful like Kuuga's Ultimate Form.
- Another 1: An armored body like Power Up and the Neo Cyclone.
- Perhaps as a nod to the Cross of Fire, Another Riders appear similar to or display abilities/quirks from their monster contemporaries:
- Another Shinobi - A rather intended case; as his similarity to Yami Shinobi is enforced with the latter having his suit recycled from the former.
- Another Zero-One - Face is based on a Humagear's skeleton bursting out before transforming and Magia's animal motif and four eyes as well as Ark's malice programming and designs.
- Another Zi-O(II) - A monster based on a Rider.
- Another Build - Consumption of Smash Bottles and going berserk are based on early victims of the Smash experiments.
- Another Ex-Aid - A living plague of Bugster Viruses.
- Another Ghost - Performs soul extraction as his modus operandi, which alluded to Knife Gamma and Katchu Gamma. Additionally, the extracted souls were used to empower himself, in a similar vein to how the Gamma World's inhabitants were suffering malfunctions of their preservation capsules and require compensation by absorbing human lives.
- Another Drive - His host is a Roidmude with the ability to use Heavy Acceleration, along with a grey skeletal face, and a similar armor design to Mashin Chaser.
- Another Gaim - Demonstrating the Overlords' abilities to command Inves and creating Crack portals. Some of the leading Overlords are also known for having minor traits of a Kamen Rider, whereas Another Gaim is an inversion of the former trope.
- Another Wizard - His host, Hayase becomes rampant after learning of his crush's engagement; The Phantoms, Kamen Rider Wizard's adversaries, are born from Gates falling into despair.

- Another Double - His Cyclone half's coloration closely resembles Nazca Dopant.
- Another Decade - The Destroyer of Kamen Riders. An anomaly from another universe, similar to how some of the monsters the original Decade fought were brought from different A.R. worlds by enemy factions or said worlds converging. His host, Swartz leading an army of past villains brings in mind Tsukasa who was once the Great Leader of Dai-Shocker.
- Another Diend - Similar head, chest and shoulder aesthetics to monsters whom he related aspects with:Jashin 14's horns, Chinomanako Diend Formation's design, Eve's eyes, Another Blade and Another Zi-O II's analogus concept.
- Another Kiva - Both the actual Rider and Bat Fangire are legitimate rulers to the Fangire race, hence the hybridization of their design. Her preying on human life force is also due to the users of Kamen Rider Kiva are supposedly of the Fangire heritage.Another Kiva’s head also has a stained glass-like appearance.
- Another Den-O - A hybridization of Den-O Sword Form and its Imagin user, Momotaros,as well as Imagin's fiction theme and possessing ability(In Ataru Hisanaga's case)
- Another Kabuto: Armor design similar to Salis Worms. When transitioning from KickHopper, Another Kabuto molted in the same way as the monsters' shed their base form to fight.
- Another Hibiki: Similar design cues from Makamou Parents, as well as design elements from S.I.C. Kabuki.
- Another Blade - A similar design to the Beetle Undead. Paralleling with the original Blade mutating into Joker, she becomes one by robbing the Joker DNA from the two existing Joker Undead.

- Another Ryuki and Ryuga - A rather obvious case; as Riders of Kamen Rider Ryuki are known for following their respective Mirror Monster resemblances.
- Another Agito - Armor design and weapon aesthetics similar in respect to the Lords and their weapons.
- Another Kuuga - Gurongi's golden accessories and brownish skin texture.
- Another 1 - Original designation as a Shocker Kaijin,composed with Grasshopper and Motorbike.
- Another Kikai is the only Another Rider based on a future Rider whose hosts are in no way related to the Rider' civilian identity.
- Each Another Rider's transformation sequence takes cues from that of their original counterpart:
- Zero-One: Neon Yellow DNA symbols circle around him during transformation, similar to when the Rider Model merges onto the original's suit
- Zi-O: Is surrounded by tubes before his form is revealed, paralleling the watches seen in the original's.
- Build: Nebula Gas appears from the suit.
- Ex-Aid: Is surrounded by pink pieces of data.
