"I don't have any energy left to faint!"
―after becoming Den-O and before boarding the DenLiner for the first time[src]

Ryotaro Nogami (野上 良太郎, Nogami Ryōtarō) is a young man with a lot of bad luck. When he first appeared, he managed to lodge himself in a tall tree while on his bike after losing control and going up a fallen sign. He has even placed a name tag in his wallet so it can be returned to him when it is stolen. Despite his hardships, Ryotaro will help anyone in need if he has the ability to do so. He refuses to accept self-sacrifice as the only means to protect others.

As a Singularity Point, he can resist the control of an Imagin contracted to him, among other things, as long as he's conscious. Due to this unique attribute, he was given the power to become Kamen Rider Den-O (仮面ライダー電王, Kamen Raidā Den'ō), a Rider who protects the timeline from the Imagins' actions. As Ryotaro continues on his mission, he meets more Imagin, each taking his body and using it as their own for the duration of their possession. Each of his personality changes affect the color of his eyes and some strands of his hair, changing its color to match the Imagin while gaining their abilities and some of their strength along with it.

  • When possessed by Momotaros, Momo is in Ryo's body. His hair spikes up slightly with a single red streak and he gains more muscular definition and the physical strength to go with it.
  • When possessed by Urataros, Ura is in Ryo's body with the right words to woo women and convince almost anybody. His hair is straight and calm and has a single blue streak going through it. He also wears a pair of black rimmed eyeglasses.
  • When possessed by Kintaros, Kin is in Ryo's body. His hair grows such that he has a ponytail with a golden yellow streak through it. However, his increased strength often results in self-injury and clumsiness.
  • When possessed by Ryutaros, Ryu is in Ryo's body, incorporating dancing into everything he does. He grows one long purple and black streak of hair and is always seen wearing a brown cap. His reckless personality infests itself upon Ryotaro, and usually causes him to destroy whatever is around if he gets out of control. One such incident occurred during the events of Climax Deka when R-Ryotaro arrested everyone who he thought looked suspicious and was part of the "Evil Organization" advertised by Negataros.
  • When possessed by Sieg, though they never forged a contract, Sieg is in Ryo's body. His hair is styled in cornrows and has several white highlights with one longer white and black lock on the left side of his face, and a white feather boa appears around his neck.
  • While Yuto was removed from time, Ryotaro gained a contract with Deneb, Deneb is in Ryo's body. His hair grows out past shoulder length with two locks of hair on each side of his head. On the right side, the lock is a neon green with a darker green streak within it.
  • When abducted by Shiro and possessed by the Ghost Imagin in the events of Final Countdown, Ryotaro's personality is overwritten by the evil Imagin's will. His hair turns snow white as it grows out long and spiky with light-yellow cat's eyes.

Imagin Possessions

Personality

A shy and rather timid man, Ryotaro was originally very weak willed. His weak will made him only be able to use Plat Form at first. Even though Ryotaro was weak willed, he was kind and friendly from the start as he helped others as Den-O.

He is also quite honest as he was very displeased at Momotaros when he tried stealing money. It was also shown in the same episode that he is very stubborn as he refused help from Momotaros until he apologized, despite nearly dying in the situation for his lack of power.

He also saw through Urataros's reason for lying at Hana was to convince Daiki to tell the truth hinting an intelligent side. He can be quite stern when necessary as he scolded Ryutaros when he nearly killed Yuto out of jealousy. He also did it understandingly though, as he knew Ryutaros didn't do it out of malice.

Ryotaro often tries to see the good in people despite how they initially appear to be, earning him the Taros's friendship and loyalty which he returned fully. As mentioned before, Ryotaro was originally weak willed, and could only access Plat form without the influence of Momotaros and the others. It was after he became more strong willed as Den-O and being with the Taros did he gain access to Liner Form by himself showing how much willpower he gained through the course of the series. Oddly enough, Ryotaro seems to have changed and acted more bold when he became younger.

He is also quite senseless on imagination and naming, as commented by Momotaros and the others. For example, naming and having Momotaros look like a peach (earning the red Imagin name as Momotaros). Another example is that when Momotaros told him to name the finisher in Liner Form, he just names it "Train Slash" (Densha Giri), which causes everyone to comment that he "lacks sense".

History

The son of Shinichi and Kayoko Nogami, Ryotaro lost his parents while in childhood with his older sister Airi caring for him along with their grandmother, making visits to the closed down Milk Dipper that his parents owned. He kept the only picture of their parents with them until he lost it, feeling regretful of it since. He and Airi eventually re-opened the Milk Dipper with the aid of his sister's fiancé. However, when Airi's fiancé mysteriously disappeared a month before the wedding, resulting in Airi's current amnesia of everything related to the man, Ryotaro dropped out of high school to help his sister at the Milk Dipper, being burdened that his sister made herself forget about the fiancé and attempts to make sure she is not reminded and be hurt.

When he finds the Rider Pass, he unwittingly becomes the protector of time and space known as Kamen Rider Den-O, fighting the Imagin who traveled to the year 2007 to grant wishes and travel further into the past to change the future to their liking. As he is a Singularity Point, he is immune to the effects of changes to the past, and he can also resist the temptations of an Imagin, as seen with the hotheaded Imagin he named Momotaros, whose contract provides Den-O with a fighting form. He is assisted by the Singularity Point Hana as well as the crew of the Den-Liner, a train that allows him to traverse time in pursuit of Imagin. They are the mysterious Owner of the Den-Liner and the dining car's waitress Naomi. Along the way, he becomes contracted to other Imagin who give him the ability to access three of Den-O's other forms. They are the lying Casanova Urataros, the herculean and narcoleptic Kintaros, and the childish yet strong Ryutaros.

Ryotaro later identifies a mysterious man who has been following him through the past as his sister's fiancé Yuto Sakurai, but then meets a young man who calls himself Yuto Sakurai and his Imagin contract Deneb, the team that can become Kamen Rider Zeronos. Upon meeting Yuto, he begins to learn more about the nature of time and the Imagin, and is told by Yuto that protecting people is not as important as protecting time. Ryotaro does not believe this and feels that the two are one in the same, and he will do so, despite his own weaknesses.

Ryotaro also briefly meets the Swan Imagin Sieg who allows him to access another form, and later the evil Kamen Rider Gaoh who hijacks the Den-Liner to travel to the past to obtain the the Gaoh-Liner, leaving Ryotaro without memory of being Den-O for a while, meeting his past self as a result, until Gaoh takes him to the Tokyo of December 26, 1988, the day Ryotaro Nogami was born, in an attempt to erase him. To defeat him, Yuto travels in time to pick up three other incarnations of Ryotaro for Urataros, Kintaros, and Ryutaros to possess and aid Ryotaro in the "Climax Scene", destroying the GaohLiner and defeating Gaoh. In the process, while getting to see his parents firsthand, Ryotaro learns how "people's memories are time".

Upon his return to the present, Ryotaro learns that because he retains only the memories of fighting Gaoh as Sword Form while his past selves are incapacitated, he has no memory of fighting as Rod, Ax, or Gun Forms. This causes Urataros, Kintaros, and Ryutaros to all dissolve into sand, from which Ryotaro's feelings manifest the Climax Cellphone K-Taros. This restores the three lost Imagin, and gives Ryotaro access to the stronger Den-O Climax Form.

When Ryotaro's actions cause the Junction Point to manifest, his sync with the Tarōs starts to dissolve as a side effect, forcing him to fight as Plat Form. However, solving the crisis in advance, the Tarōs use their powers to create the DenKamen Sword so Ryotaro can assume the powerful Den-O Liner Form so he can fight on his own. Shortly thereafter, he meets the Singularity Point Kai, who seeks to make the Imagin's future the true future, by seeking to destroy the Junction Point, who is later found to be Ryotaro's sister Airi. As a result, Ryotaro falls into a trap set up by Kai to keep him from Airi, with Kintaros and Urataros sacrificing themselves so Ryotaro can return to the present. In the process, Ryotaro learns that his missing memory is tied to the true identity of the one who will ensure that the flow of time and space leads to the future without Imagin: his niece who is revealed to be Hana/Kohana.

After the final battle is over, Ryotaro is saddened by the supposed loss of the Tarōs, only to find out that they and Sieg, still existing due to their memories together, are hiding in a ditch attempting to surprise him. Ryotaro is overjoyed that they are all still alive and celebrates happily. With his mission to protect time from Kai and his Imagin finished, Ryotaro relinquishes his Rider Pass back to the Owner of the Den-Liner, thanking everyone for what they have done for him. As he rides his bike back to the Milk Dipper, he is greeted by all of the riders of both the Zero-Liner and the Den-Liner who bid him a final farewell before departing into the time stream. Ryotaro smiles as they pass by, knowing that he will meet them again someday in the future.

Later, when an Imagin named Negataros steals the Rider Pass from Owner, Ryotaro joins the newly formed Den-Liner Police to stop Negataros and his "Evil Organization", succeeding thanks to the aid of Kamen Rider Kiva. After the case was closed, Ryotaro and the Den-Liner crew keep the Den-Liner Police going just for kicks.

Ryotarou And Koutarou

Ryotaro meets his future grandson Kotaro inside the New Den-Liner

However, Ryotaro is forced to resume being Den-O when he is possessed by the Ghost Imagin for Shiro, using the Signality Point in order to travel into the past while having the possessed Ryotaro as his enforcer, Kamen Rider Yuuki Skull Form. But through Momotaros' aid, Ryotaro manages to regain control so he can let his Imagin partner in his body to purge the Ghost Imagin before they finish the Imagin off in Climax Form. But during the climatic final battle against the revived Imagin, Ryotaro, Momotaros, and Kotaro assume their rider forms to defeat Shiro when he becomes Yuuki Hijack Form.

After formally meeting his grandson, Ryotaro promises him he won't divulge any learned knowledge of the future as he takes Kotaro and Teddy home on the Den-Liner.

Decade

Ryotaro2

Ryotaro de-aged

With Ryotaro off investigating an error in the timeline, there is no one person with the Tarōs that has the power of Den-O and the Tarōs manage without a permanent body to use. Following the departure of Ryotaro, prior to Tsukasa and company entering Den-O's World), the Tarōs suddenly lost the ability to maintain their physical forms due to the actions of an unknown force that is altering their present at some time in the past. The alteration of the present also ended up de-aging Ryotaro a few years, making him a young boy/teenager as a result.

Seeing the Mole Imagin surfacing to be connected to it, Momotaros possesses Tsukasa to fight one. After being evicted from Tsukasa's body by Natsumi's pressure point, Momotaros attempts to re-possess Tsukasa, but ends up in the body of Yusuke instead. After Tsukasa manages to get Momotaros to talk back at the Hikari Photo Studio, M-Yusuke storms off to solve the mystery behind his world's crisis.

As he is trying to figure out why buildings are disappearing, M-Yusuke is confronted by Daiki who wishes to know where the DenLiner is, revealing a DenLiner Final FormRide Card in his possession that would supposedly allow Momotaros to regain his physical form. Momotaros refuses, and then begins a fight with Diend as Den-O Sword Form, escalating against him with Diend using Sasword and Saga to outnumber him before he is sent plummeting off of a building. He survives as Diend takes his leave for Momotaros to reconsider.

Elsewhere, as Tsukasa and Natsumi investigate Den-O's World by finding the DenLiner and use it to go back to the time it started, Urataros, Kintaros, and Ryutaros each possess Tsukasa, revealing that they were warned of Decade and believe he is connected to the disturbances in their world. When Tsukasa manages to force them all out, they take over Natsumi's body, each using her to fight Decade in their respective Den-O Form as Decade counters as Agito. During the fight, both Riders are transported to another dimension similar to where the Rider War took place in Natsumi's dream. The fight would ultimately end in a stalemate as the DenLiner picks them up. Upon entering, they are greeted by Naomi, Kohana, and Owner, who would talk to them about teaming up to solve the mystery.

After tending to his injuries from taking out another Mole Imagin, M-Yusuke is confronted by Tsukasa before he senses the Imagin he's looking for, the Alligator Imagin. Chasing him to the past, Den-O is nearly killed by the Alligator Imagin when Decade and Diend intervene, with Diend using his Riotrooper card to hold the Imagin at bay. Diend would once again offer Momotaros a true body of his own, but Decade somewhat defends Momotaros, regaining his access to Den-O's powers.

File:Img 8.jpg

Through the modified Final Form Ride Card, Momotaros regains his physical form and, after a slight misunderstanding from Yusuke, takes out the Alligator Imagin by using Kuuga Gouram as part of his Finishing Attack. Although the crisis is over another occurs after Momotaros returns to the DenLiner, with the Tarōs disappearing and Momotaros ending up on Onigashima as part of the Oni Conquest legend.

Despite not appearing in the web-exclusive series, Den-O and 13 Heisei Riders were the projections of the Ganbarizing Critical Strike.

While Ryotaro doesn't appear in this event, he is mentioned when the Game World Momotaros mistakenly called Emu Hojo‎ "Ryotaro".[Kamen Rider × Super Sentai: Chou Super Hero Taisen]

Kamen Rider Zi-O

Kamen Rider Build: Be The One

Among the first 18 Heisei Riders, Den-O fought against numerous monsters in a melee briefly witnessed by Sento Kiryu before being caught in the crossfire as Kamen Rider Zi-O BuildArmor used his Vortex Time Break to wipe out his enemies. [Kamen Rider Build: Be The One]

Kamen Rider Heisei Generations Forever

During the events of Kamen Rider Heisei Generations Forever, the main villainTid forcibly turned Ataru into Another Den-O to use as a pawn for his grand scheme. Tid, Another Den-O, and their grunts proved too formidable for FuutarosSougo Tokiwa/Kamen Rider Zi-O and Sento Kiryu/Kamen Rider Build to defeat on their own, both Kamen Riders being forced out of their rider forms in battle. Just when it seemed all hope was lost for them though, flashes of light suddenly teleported everyone (barring Tid) within their vicinity. Finding themselves at the KingLiner, Sougo and his friends were saved by the real Den-O. Each Taros took turns as Den-O to attack their fake counterpart, with Urataros as Den-O Rod Form being the one to finish off Another Den-O.

Introducing themselves as "warriors of love", Urataros watched Sougo and the others return to where they came from. Momotaros, Kintaros, and Ryutaros then re-appeared in their Imagin forms, arguing with what they should call themselves as Den-O. During their banter, Urataros undid his transformation, revealing that they had been possessing Ryotaro's body all along. Though Ryotaro remained silent since Urataros was still possessing him, he smiled when Momotaros told him that they would always remember one another.

Later on, Momotaros in Den-O Sword Form reppeared to help Sougo again, fighting off Tid's remaining forces and delivering a Rider Kick alongside the other primary riders to defeat Another Ultimate Kuuga.

Den-O (Battride War)

Kamen Rider Den-O appears as one of the Main Riders in the video game Kamen Rider: Battride War, which unites the riders of the Heisei era from Kuuga to Wizard.

Den-O has access to Sword, Rod, Ax, and Gun Forms with Climax Form as his "super mode", though if any form takes too much damage it will be rendered unusable for the rest of the stage.  Liner Form is present as a standard form (and is the only form that can't be disabled), but if the player activates their finisher while using it, instead of Climax Form their super form will be an enhanced version of Liner Form after using Densha Giri.

Kamen Rider Den-O reappeared in Kamen Rider: Battride War II, summoned by Cinema along with the remaining Heisei Riders in order to create the "ultimate movie". Den-O's stage is based of from Kamen Rider Den-O: I'm Born!, with Den-O Sword Form is set as default playable form with no form changes (including final forms) and Kamen Rider Gaoh as his main enemy in this mission. The game adds Wing Form which can be unlocked after I'm Born! mission, and Super Climax Form which served as Den-O's Ultimate Final Form for both original Climax Form and enhanced Liner Form.

Fighting skill

Originally one of the weakest Riders in the franchise for his timidness. Ryotaro often relied on Momotaros and the others to fight while using his body as a vessel. As he trained more with the others he learned to fight more by himself, shown when he gained access to Liner Form. Although he became more capable at fighting alone, Ryotaro seems to still work best with the other Taros through teamwork.

Powers and Abilities

Singularity Point Abilities
As a Singularity Point, Ryotaro possessed some of these abilities.
Temporal Protection
Even after a timeline paradox, Ryotaro's mind and physical appearance retains it's original state. This makes him invaluable against time manipulators, as most of the other primary Riders do not seem to have this protection.
Indomitable Will
Singularity Points possess the ability to withstand the temptation of free wishes that the Imagin offers and can expel them whenever Ryotaro is in consciousness.

Forms

By swiping a Rider Pass across the SetTouch, Kamen Rider Den-O is able to pass through four forms, each with their own strengths and weaknesses. Each of the forms (excluding Plat Form, Climax Form, and Liner Form) is based on a specific mythological hero along with motifs relating to the respective legends. However, when Ryotaro (post-series) and the Imagin use the Rider Pass, they bypass the Plat Form to assume their respective Den-O Form.

Plat Form
File:Den-O Plat Form.PNG

Plat Form

  • Rider height: 180 cm.
  • Rider weight: 80 kg.
  • Ability perimeters
    • Punching power: 1 t.
    • Kicking power: 3 t.
    • Maximum jump height: 10 m.
    • Maximum running speed: 100 m. per 10 sec.

Plat Form (プラットフォーム, Puratto Fōmu) is Den-O's most basic default form undersuit, and, for a long while, Ryotaro's default form. This is because of his meek personality not generating enough willpower to give himself a proper Den-O form, until near the end, where he finally generates enough willpower to make his default form become Liner Form.

Plat Form is a black and white form that is activated when first initiating a transformation using a Rider Pass. If the corresponding color-coded button is selected, then by swiping the Pass once more, a form change will occur.

Ryotaro rarely uses this form, as it does not have sufficient armor and pales in comparison to the abilities of the other forms. Only when he does not want the assistance of the Tarōs or is transitioning into Liner Form, does he use this form. Plat Form is designed and named after a railway platform, as a reference to the fact Den-O Riders use their Platforms as a armor template.

Plat Form (while possessed by Sieg)

While Ryotaro is possessed by Sieg and is transforming into Wing Form, the Aura Skin becomes gold.

Appearances: Den-O Episodes 1-24, 26-27, I'm Born!, 28-49, Kamen Rider Den-O & Kiva: Climax Deka


Once Ryotaro activates any of the four buttons on the Rider pass, the chosen Imagin then takes control and a transformation follows. It should be noted that these are not Ryotaro's "true" forms as these are all essentially the Imagin as riders, which they can also activate on their own supposing they have their own physical forms and are not in need of a host body.

Sword Form
File:Den-O-sword.jpg

Sword Form

Den-O-Ryotaro-Momotaros

M-Ryotaro

"Sword Form!"
―Transformation announcement[src]
  • Height: 190 cm.
  • Weight: 87kg

Ability Perimeters:

  • Punching power: 5 t.
  • Kicking power: 7 t.
  • Maximum jump height: 35 m.
  • Maximum running speed: 100 m. per 5.2 sec.

When possessing Ryotaro (or anyone else) or by himself, Momotaros can assume Den-O's Sword Form (ソードフォーム, Sōdo Fōmu) through the Terminal Buckle, the first and most used form in the series. When in Sword Form he uses the DenGasher as a standard sword-style weapon. This form is the most balanced among Den-O's forms, probably due to Momotaros' prominence among the other Imagin.

Sword Form's typically used Full Charge finisher is the Extreme Slash (エクストリームスラッシュ, Ekusutorīmu Surasshu), which is merely labeled by Momotaros as "My Finishing Move!" (俺の必殺技!, Ore no Hissatsu Waza!), and famously gives it "Parts" (パート, Pāto), despite said parts, those being Parts 2, 2 Dash, 3, and 5 (four was skipped because of tetraphobic reasons, even if Momo wouldn't admit it to Ryotaro) being identical to each other, in the aspect that the blade of the DenGasher detaches and flies in the path of Den-O's swings, ending with a chop that bifurcates. He also uses a "Special Version" (特別編, Tokubetsu-hen) in I'm Born! to finish off Gaoh which resembles the aforementioned parts, the only difference is that the Full Charge is used twice, with the blade striking Gaoh across the chest when it emerged from the ground.

There is also a Final Version (ファイナルバージョン, Fainaru Bājon) used against the Death Imagin which uses energy from the other Taros, Sieg, and Kamen Rider Zeronos Vega Form.

In the Cho Den-O series, Sword Form also has a triple Roundhouse DenRider Kick (デンライダーキック, Den Raidā Kikku), with Momotaros dubbing this his "Super Finishing Attack".

The DenKamen Mask resembles two halves of a peach, which is based on the story of Momotaro, with Momo being based off of the Oni Momotaro fought, much to Momo's constant chagrin, as Imagin are given their body's form from their host's imagination, with Ryotaro's imagination being notoriously poor.

Sword Form's ending theme is entitled "Double-Action".

Appearances: Den-O Episodes 1-11, 14, 16, 18-20, 23, 26-27, I'm Born!, 28, 30, 32-33, 36, 38-39, 41, 44-45, 49, Kamen Rider Den-O & Kiva: Climax Deka


Rod Form
File:Den-O-rodform.jpg

Rod Form

Den-O-Ryotaro-Urataros

U-Ryotaro

"Rod Form!"
―Transformation announcement[src]
  • Rider height: 187 cm.
  • Rider weight: 102 kg.

Ability perimeters:

  • Punching power: 4.5 t.
  • Kicking power: 9 t.
  • Maximum jump height: 20 m.
  • Maximum running speed: 100 m. per 9 sec.

When possessing Ryotaro (or anyone else), or by himself, Urataros can assume Rod Form (ロッドフォーム, Roddo Fōmu). The DenGasher forms into a rod-style weapon in this form. Rod Form has the ability to fight underwater as well as extra protection. Stats-wise compared to Sword Form, it has increased kicking power, while losing some speed & punching power, and a drop in max jumping height. This is one of the more least seen forms, as Urataros rarely fights but comes through when a fight is close to water or when the other Imagin are unable to fight.

Rod Form's Full Charge finisher is also one of the two base forms that have a Rider Kick, the second being Sword Form in the Cho Den-O Series. Urataros first performs the Solid Attack (ソリッドアタック, Soriddo Atakku), where he throws the charged DenGasher like a harpoon, which when it makes contact, it turns into a paralyzing blue hexagonal symbol, shaped like that of Urataros' own belt buckle. Once done, he attacks with the DenRider Kick (デンライダーキック, Den Raidā Kikku) to defeat the stunned opponent. The Aura Armor and DenKamen mask resembles a Sea Turtle, the animal associated with the story of Urashima Taro.

Rod Form's ending theme is entitled "Double-Action Rod form".

Appearances: Den-O Episode 6, 8-9, 15, 18, 22, 24, 27, I'm Born!, 34, 42, 44, 48-49, Kamen Rider Den-O & Kiva: Climax Deka


Ax Form
File:Den-O-axeform.jpg

Ax Form

Den-O-Ryotaro-Kintaros

K-Ryotaro

"Ax Form!"
―Transformation announcement[src]
  • Height: 185 cm.
  • Weight: 93 kg.
  • Punching power: 8 t.
  • Kicking power: 5 t.
  • Maximum jump height: 30 m.
  • Maximum running speed: 100 m. per 7 sec.

When possessing Ryotaro (or anyone else), or by himself, Kintaros assumes Ax Form (アックスフォーム, Akkusu Fōmu). In this form, the DenGasher forms an ax for short-ranged attacks. Compared to Sword Form, Ax Form gains increased punching power and defenses but loses speed and kicking power.

This form is Den-O's physically strongest base form due to Kintaros' own brute strength. Kintaros tends to fight as Den-O whenever he senses crying or when hears anything similar to the Japanese word for "cry" (鳴く, Naku).

This form's Full Charge finisher is the Dynamic Chop (ダイナミックチョップ, Dainamikku Choppu), which consists of Kintaros charging the DenGasher, then chucking it skyward, jump up to catch it, then come down with a energized DenGasher backed with the momentum of the fall. Typically, Kintaros says the name of the finisher afterwards, but he has said this phrase prior to making the move once.

The aura armor is golden yellow and the motif is of an axe, with a DenKamen Mask resembling the kanji for gold (), all of which are elements to the story of Kintaro.

Ax Form's ending theme is entitled "Double-Action Ax form".

Appearances: Den-O Episodes 10-12, 15, 18, 23, 24, 27, I'm Born!, 28, 31, 35, 40, 44, 47, 49, Kamen Rider Den-O & Kiva: Climax Deka


Gun Form
File:RyutarosDEn-O-gun-1.png

Gun Form

Den-O-Ryotaro-Ryuutaros

R-Ryotaro

"Gun Form!"
―Transformation announcement[src]
  • Height: 197 cm.
  • Weight: 98 kg.
  • Punching power: 6 t.
  • Kicking power: 10 t.
  • Maximum jump height: 42 m.
  • Maximum running speed: 100 m. per 4 sec.

When possessing Ryotaro (or anyone else), or by himself, Ryutaros assumes Gun Form (ガンフォーム, Gan Fōmu). The DenGasher forms a gun for short and long ranged attacks.

Gun Form displays an increase in power, speed, and defense easily making it the most powerful out of Den-O's four basic Imagin forms, though the problem with the form lies mainly with its user's mentality. Ryutaros tends to fight on a whim, as he overpowers the other Taros and Ryotaro himself, and he is the least skilled (presumably because of his age) and tends to cause more collateral damage than the other forms due to his low precision skills and the high power of the DenGasher's ammunition.

Ryutaros incorporates break dancing into his fighting style making his movement somewhat unpredictable, though this often helps with creating collateral damage in the first place, as the wild shots would only hit the surroundings of the opponents early on.

This form's finisher is the Wild Shot (ワイルドショット, Wairudo Shotto), where a ball of energy forms in the DenGasher's muzzle, which is also fed by the energy from the orbs on Gun Form's torso armor.

The Aura Armor and DenKamen resemble a dragon, the animal associated with Tatsu no ko Taro.

Gun Form's ending theme is entitled "Double-Action Gun form".

Appearances: Den-O Episodes 13-17, 21-22, 26-27, I'm Born!, 31-32, 37, 44, 49, Kamen Rider Den-O & Kiva: Climax Deka


Wing Form
File:Den-O-wing.jpg

Wing Form

Den-O-Ryotaro-Sieg

S-Ryotaro

"Wing Form!"
―Transformation announcement[src]
  • Height: 193cm
  • Weight: 90kg
  • Punching power: 4 t.
  • Kicking power: 8 t.
  • Maximum jump height: 50 m.
  • Maximum running speed: 100 m. per 3.8 sec.

When possessing Ryotaro (or anyone else) or by himself, Sieg assumes Wing Form (ウイングフォーム, Uingu Fōmu) by placing the Wing Buckle (ウイングバックル, Uingu Bakkuru) over the Terminal Buckle.

Unlike the other forms, Wing Form has the DenGasher become two weapons: an boomerang and a handaxe. Wing Form's suit resembles Sword Form but the Aura Skin becomes gold, different shoulder blades and thicker thigh armor are used, and the visor is blue and resembling swan wings, the bird of the ballet Swan Lake, which Sieg is based after.

This form gives Den-O more mobility than Gun Form could provide via a fractionally faster running speed and a somewhat higher jumping height max, though Wing Form has lower offensive output.

Wing Form's Full Charge finisher is the Royal Smash (ロイヤルスマッシュ, Roiyaru Sumasshu).

Wing Form's ending theme is entitled "Double-Action Wing form".

Appearances: Den-O Episode 24, 27, I'm Born, 49



The Den-O Belt works by drawing in free energy from the surrounding area, allowing it to generate the Den-O suit, which consists of a soft but durable material called Aura Skin (オーラスキン, Ōra Sukin) and tough armor called Aura Armor (オーラアーマー, Ōra Āmā). As the name implies, Aura Skin and Armor are attuned to the wearer's individual aura; because of Ryotaro's weak will, he can only generate the basic Plat Form. However, possession by Imagin causes the Aura Skin and Armor to reconfigure themselves into a form that matches the Imagin's will, as well as generating a facemask called a Denkamen (電仮面, Denkamen).

Climax Form

Climax Form

"Momo-Ura-Kin-Ryu! Climax Form!"
―Transformation announcement[src]
  • Height: 190 cm.
  • Weight: 119 kg.
  • Punching power: 8 t.
  • Kicking power: 10 t.
  • Maximum jump height: 42 m.
  • Maximum running speed: 100 m. per 4 sec.

Climax Form (クライマックスフォーム, Kuraimakkusu Fōmu) is Den-O's sixth and second most powerful form, gained when all Tarōs but Momotaros faded away and Ryotaro's desire not to lose them created the K-Taros cell that is attached to the Den-O Belt once the code 3-6-9-# is entered. Climax Form is basically a stronger version of Sword Form that incorporates the DenKamen of the other three primary Den-O forms onto various parts of the armor.

Due to the nature of Climax Form, the Tarōs need to work as a unit to fight, and their strengths are incorporated into Climax Form. Rod Form's mask is on the right shoulder with Urataros controlling the right arm, Ax Form's mask on the left shoulder with Kintaros controlling the left arm, and Gun Form's mask on the chest with Ryutaros control the legs.

Climax Form's Full Charge finishers are announced on the Belt as "Charge and Up" (チャージアンドアップ, Chāji Ando Appu), allowing Den-O to perform various finishing techniques:

  • Boisterous Kick (ボイスターズキック, Boisutāzu Kikku): The DenKamen on Climax Form's body enter Kick Mode (キックモード, Kikku Mōdo), moving to the kicking leg in question via the train tracks that cover the suit, with Urataros' DenKamen moving down first, followed by Kintaros and Ryutaros. Seconds before the kick connects, the antennae on Urataros' DenKamen move down.
  • Boisterous Punch (ボイスターズパンチ, Boisutāzu Panchi): The DenKamen on Climax Form's body enter Punch Mode (パンチモード, Panchi Mōdo), moving to the punching arm in question via the train tracks that cover the suit, with Kintaros' DenKamen moving down first, followed by Urataros and Ryutaros, using the ax blade on the DenKamen to full usefulness.
  • Boisterous Shout (ボイスターズシャウト, Boisutāzu Shauto): Ryutaros' DenKamen opens up like a dragon's maw, and shootings several homing missiles from the DenKamen.
  • Boisterous Slash (ボイスターズスラッシュ, Boisutāzu Surasshu): It is executed very similarly to Sword Form's Extreme Slash Part 2, only powered by the energy from Climax Form. Here, Momotaros announces "My/Our Finishing Move, Climax Version!" (俺(たち)の必殺技、クライマックスバージョン!, Ore(-tachi) no Hissatsu Waza, Kuraimakkusu Bājon!).

Super Climax Form

Super Climax Form

  • Rider height: 190 cm.
  • Rider weight: 119 kg.
  • Ability perimeters
    • Punching power: 8 t.
    • Kicking power: 10 t.
    • Maximum jump height: 50 m.
    • Maximum running speed: 100 m. per 3.8 sec.

Super Climax Form (超・クライマックスフォーム, Chō Kuraimakkusu Fōmu), originally advertised as Kamen Rider Cho Den-O (仮面ライダー超・電王, Kamen Raidā Chō Den'ō), is Den-O's eighth and true final form, exclusive to the Cho-Den-O Series and first appearing in Cho Kamen Rider Den-O & Decade NEO Generations: The Onigashima Battleship.

It is the evolved form of the original Climax Form in being a stronger version of Sword Form that incorporates the DenKamen of the other three primary Den-O forms onto various parts of the armor. However, Super Climax Form also includes Sieg's DenKamen (due to his close proximity to the formation at the time) as wings on the back of Den-O Climax and a Wing Form insignia on the mask. While not any stronger than the original Climax Form, it does gain Wing Form's greatest attributes for its agility stats, those being in running speed and jumping height.

Super Climax Form's finisher is an enhanced version of Climax Form's Boisterous Kick, where Den-O jumps into the air, then uses Wing Form's DenKamen to form giant wings to gain additional altitude, then flies towards target before striking the target with a flying kick. However, in the film of Neo Generations, it doesn't use Urataros' DenKamen to contact with.

Liner Form

Liner Form

"Liner Form!"
―Transformation announcement[src]
  • Rider height: 195 cm.
  • Rider weight: 94 kg.
  • Ability perimeters
    • Punching power: 6 t.
    • Kicking power: 7 t.
    • Maximum jump height: 45 m.
    • Maximum running speed: 100 m. per 3.5 sec.

Liner Form (ライナーフォーム, Rainā Fōmu) is Den-O's second final form, gained when the Tarōs created the DenKamen Sword for Ryotaro to use when their synchronization with him was starting to fail whenever in the past.

In order to initially transform into Liner Form, the Rider Pass must be put in a slot in the back of the blade of the DenKamen Sword, while also putting the K-Taros onto the Terminal Buckle.

This form, solely controlled by Ryotaro with the Imagin using the DenKamen Sword as a means of communication, is themed around Den-Liner in transformation and attack. Ryotaro also utilizes each Imagin's respective fighting style when their mask is selected on the DenKamen Sword (eg. Kintaros' strength and defense in KinAx mode, and Ryutaros' breakdancing techniques in RyuGun mode). It soon becomes the only form Ryotaro is able to use while fighting in the past after all of his other forms become inaccessible.

Although considerably versatile, Liner Form does not hold any significant strengths over Den-O's other forms besides being the fastest, which sometimes leaves Ryotaro at a disadvantage. This form was also inaccessible at first without the Taros to assist him.

Later on, Ryotaro was able to use this form by himself though, as shown in the final episode of Den-O's series, which was taken as a sign of his now stronger will. Liner Form is also able to use the DenGasher, though this is only shown when the DenKamen Sword was left behind following the Taros all joining the same battlefield as Den-O.

Liner Form's ending theme is entitled "Real-Action".

Appearances: Den-O Episode 36, 38-39, 42-43, 45-47, Saraba Kamen Rider Den-O: Final Countdown.

Behind the scenes

Portrayal

Ryotaro Nogami is portrayed by Takeru Satoh (佐藤 健, Satō Takeru) and by Takuya Mizoguchi (溝口 琢矢, Mizoguchi Takuya) as a child. Mizoguchi returned to portray the present-Ryotaro after the character was de-aged in Cho Den-O series. While in the game series of Kamen Rider: Climax Heroes and Battride War, he was voiced by veteran voice actor Yuta Kasuya.

Rider No.

As the leading Rider protagonist of Kamen Rider Den-O, Ryotaro Nogami (Kamen Rider Den-O) is labeled Kamen Rider #23 (仮面ライダー23号, Kamen Raidā Nijūsangō) and Heisei Rider #8 (平成ライダー8号, Heisei Raidā Hachigō). [Quiz! Decade Countdown!!]

Notes

Den-O Concept Art

Early design of Den-O.

  • Parrtly due to Takeru Satoh (Ryotaro's original actor) having been restricted from appearing in future Kamen Rider movies by his agency, Ryotaro's position as the transformer of Den-O became replaced with the Taros (Particularly Momotaros) in future Kamen Rider Movies succeeding the Cho Den-O Trilogy.
    • With this, many fans speculate that Ryotaro has retired as a Kamen Rider all together, opting to live a normal life. 
    • As of Heisei Generations Forever though, Takeru Satoh as Ryotaro officially reappeared as Kamen Rider Den-O, helping his succcessors fight Tid. This shows that Ryotaro has not quit being Den-O all together, and will fight alongside the Taros when necessary. 
    • Ironically, many previous Kamen Rider movies involved villains manipulating time travel, but with Ryotaro not being present, Den-O was not only unable to stop them, but even became a Shocker Rider at one point due to a time paradox. 
  • Although it seemed that Ryotaro couldn't transform into Liner Form without help from the other Taros, It seems that as the series progressed, Ryotaro learned to transform without their influence as he gained a stronger will.
    • Interestingly enough, Ryotaro seemed to have stopped using Liner Form when he de-aged, instead for some reason using Plat Form when unable to get help from the other Taros.
  • Despite being called the weakest Rider in Plat Form by some, Riderman, Skyrider in his original form, G3 Mild, and Kamen Rider Joker are all statistically weaker than him.
  • Early designs of Climax Form included a version where the Denkamen was used as a handheld weapon like the DenGasher's Rod Mode.
