Kamen Rider Den-O (仮面ライダー電王 Kamen Raidā Den'ō?) is the primary protagonist and eponymous character of the 2007 Kamen Rider Series, Kamen Rider Den-O.

Ryotaro Nogami[edit]

Ryotaro Nogami (野上 良太郎 Nogami Ryōtarō?) is a young man with an intense streak of bad luck. Having lost his parents at a young age, he lived with his grandmother and older sister Airi, visiting his parents' library/café called the Milk Dipper as often as possible. He also kept a photograph of his parents until he lost it, regretting that day ever since. He and Airi eventually reopen the Milk Dipper along with Airi's fiance. However, her fiance mysteriously disappears a month before their wedding and she is suddenly struck with amnesia of all events relating to him. Ryotaro begins to take care of Airi and help at the Milk Dipper. He makes sure that she is always happy and never reminded of her fiance and become burdened by the loss, even though he questions if it is right for Airi to forget completely. Ryotaro will help anyone in need if he has the ability to do so, regardless of his bad luck; he also refuses to accept self-sacrifice as the only means to protect others.

One day early in 2007, Ryotaro comes across the Rider Pass, the DenLiner, Hana, and becomes possessed by the Imagin Momotaros. Hana discovers that Ryotaro is a Singularity Point, a human immune to changes in history as well as the lure of the Imagin's wish granting. This traps Momotaros in Ryotaro's body and enables both to become Kamen Rider Den-O (Sword Form). As such, Ryotaro is drafted by the Owner of the DenLiner to become a keeper of space-time; Kamen Rider Den-O destroys Imagin that travel to the past to change the future, enabling that the future of the humans remains intact. Along the way, Ryotaro becomes contracted to the Imagin Urataros, Kintaros, and Ryutaros (collectively called the Tarōs), enabling Den-O to transform into additional forms.

Ryotaro also discovers the existence of Yuto Sakurai, the younger incarnation of his sister's fiance, and his Imagin partner Deneb who become Kamen Rider Zeronos. The group also help the Imagin Sieg who nearly ceases to exist, and later use his partnership with Ryotaro to fight the evil Kamen Rider Gaoh when the Edo period is threatened (the events of Kamen Rider Den-O: I'm Born!). It is also in this travel back in time that Ryotaro meets his younger self dubbed "Kotaro" who becomes Kamen Rider Mini Den-O to help with the fight. When three of the Tarōs' existence is threatened by their part in defeating Gaoh, Ryotaro's feelings for the friendship he has with them creates the K-Taros cellphone, bringing them back to life and allowing him to become Climax Form.

When Kai, the Singularity Point of the Imagin's future, appears to further his plan to destroy the Junction Point to ensure that the flow of time ensures that the Imagin will exist rather than humans, Ryotaro's sync with the Tarōs begins to fade, forcing him to fight on his own as Liner Form. As he eventually discovers that the Junction Point is the unborn child of Airi and Sakurai, Ryotaro discovers that they had sacrificed their love and marriage for the sake of their child through Airi's ownership of the ZeroLiner and that their child is none other than Ryotaro's travelling companion Hana (who has been de-aged and become known as Kohana). Ryotaro, the Tarōs, Yuto, and Deneb work together to save Hana and defeat Kai, ensuring that the Imagin will never exist. As Ryotaro begins to lament that he will never see the Tarōs again, they (along with Sieg and Deneb) make themselves known, having been saved due to their time with the Kamen Riders. The Owner tells Ryotaro that his work is done, and Ryotaro gladly relinquishes the Rider Pass, knowing that he will meet the Tarōs in the future.

Some time after this, Ryotaro is asked by the Owner to help in finding other Imagin who survived Kai's defeat and disappearance from history. It is during this time Ryotaro comes across both the evil Negataros and the half-Fangire Wataru Kurenai (the events of Kamen Rider Den-O & Kiva: Climax Deka). After Negataros is defeated, Ryotaro is allowed to live his life as he wishes once more. However, he is abducted by Shiro and contracted to the Ghost Imagin, enabling him to briefly become Kamen Rider Yuuki Skull Form. When the Tarōs and his grandson from the future Kotaro save him, he becomes Den-O once more to defeat Shiro and save all space-time from being reversed such that everyone alive becomes dead and all those who have died come back to life, as well as ensuring that his ancestors in this time period meet (the events of Saraba Kamen Rider Den-O: Final Countdown).

Later, Ryotaro becomes de-aged in a similar way to his niece Hana, and must assist his grandson and Tsukasa Kadoya save space-time from the Oni Brothers Goludora and Shilubara (the events of Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship). While still in his younger incarnation, Ryotaro also helps Yuto save Airi from the Piggies Imagin, help Kotaro and a young woman deal with her contract with the Mantis Imagin, and inadvertently assist Daiki Kaito steal an item from history and escape from the Time Police (the events of Kamen Rider × Kamen Rider × Kamen Rider The Movie: Cho-Den-O Trilogy).

Throughout the original television series and the first three films, Takeru Satoh portrays the character of Ryotaro Nogami. Beginning with the character's brief appearance in Kamen Rider Decade, and continuing throughout the Cho-Den-O Series, Takuya Mizoguchi portrays Ryotaro. Mizoguchi had originally portrayed the younger iteration of Ryotaro called "Kotaro" in the Kamen Rider Den-O: I'm Born! film.

Alternate personalities[edit]

As a Singularity Point, Ryotaro can resist the control of an Imagin contracted to him, among other things, as long as he is conscious. Due to this unique attribute, he was given the power to become Den-O, a Kamen Rider who protects the timeline from the Imagin's actions. As Ryotaro continues on his mission, he meets multiple Imagin, each giving him a unique personality for the duration of their possession. Each of his personality changes affect the color of his eyes and a strand of his hair, changing its color and sometimes his appearance to match the Imagin.

  • When possessed by Momotaros, Ryotaro assumes the mannerisms of a self-absorbed punk. His hair spikes up slightly with a single red streak and he gains more muscular definition and the physical strength to go with it. He takes on an extremely rash and ignorant personality, exactly like Momotaros. This form is referred to in Japanese media as M-Ryotaro.
  • When possessed by Urataros, Ryotaro assumes the mannerisms of a teen idol casanova 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 and sometimes a suave attire. He takes on a very professional and crafty personality, exactly like Urataros. This form is referred to in Japanese media as U-Ryotaro.
  • When possessed by Kintaros, Ryotaro assumes the mannerisms of a martial artist. His hair grows such that he has a ponytail with a golden yellow streak through it. He takes on a very noble and firm personality, exactly like Kintaros. However, his increased strength often results in self-injury and clumsiness. His usual attire in this state is a yellow-and-black striped kimono. This form is referred to in Japanese media as K-Ryotaro.
  • When possessed by Ryutaros, Ryotaro assumes the mannerisms of a 1980s hip-hop break dancer, incorporating it 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 occurs during the events of Climax Deka when Ryutaros in Ryotaro's body arrests everyone who he thinks looks suspicious and therefore must be part of the "Evil Organization" advertised by Negataros. This form is referred to in Japanese media as R-Ryotaro.
  • When possessed by Sieg, though they never forged a contract, Ryotaro assumes the mannerisms of a prince. 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. This form is referred to in Japanese media as W-Ryotaro (the W standing for "Wing").
  • While Yuto is removed from time, Ryotaro gains a contract with Deneb, assuming the mannerisms of a butler while possessed by Deneb with an extremely polite and overly friendly personality. 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. This form is referred to in Japanese media as D-Ryotaro.
  • 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 spiked. His eyes turn a ghostly light yellow. This form is referred to in Japanese media as A-Ryotaro (the A standing for "Another") as well as G-Ryotaro.

Kamen Rider Den-O[edit]

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, Liner Form and Super Climax Form) is based on a specific mythological hero along with motifs relating to the respective legends. However, when any of the Taros uses the Rider Pass, they bypass the Plat Form to assume their respective Den-O Form. Its overall motif is the shinkansen.

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?).

Plat Form[edit]

Plat Form (プラットフォーム Puratto Fōmu?), Den-O's most basic and weakest 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, and swiping the Pass once more, a form change will occur. Ryotaro rarely uses this form, as it has the weakest armor and pales in comparison to the abilities of the other forms, unless when he either does not want the assistance of the Tarōs or transitioning into Liner Form. Although he still has access to the weapons of other forms in Plat Form, his frail physique and insufficient skill with weapons means that the weapons would not do him much good anyway. Plat Form is designed and named after a railway platform (プラットホーム purattofōmu?).[1]

Sword Form[edit]

Sword Form (ソードフォーム Sōdo Fōmu?) is Kamen Rider Den-O's first (and most common) form, used when Ryotaro is possessed by Momotaros. In Sword Form, he uses the DenGasher as a standard sword-style weapon. Sword Form is the most balanced of all his forms, possibly because of Momotaros' prominence among the other Imagin. Momotaros himself once assumed Sword Form during the events of "Final Countdown" to battle Kamen Rider Yuuki. Every so often, Momotaros will develop a new Finishing Attack (必殺技 Hissatsu Waza?) that he uses to finish off Imagin, and has developed Parts 1, 2, 2' (2-dash), 3, 5, Special Version (used in "I'm Born!"), and the Imagin-assisted Final Version, although parts 2, 3, and 5 are essentially identical. Special Version is nearly identical to 2, 3, and 5, but uses a double Full Charge and only strikes the enemy on the rebound, while Final Version is an extended attack that uses the energy of the other Taros, Sieg, and Zeronos. Sword Form also has a triple roundhouse Rider Kick that Momotaros refers to as his "Super Finishing Attack", though it was never used during the series, but within the Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship movie. The eyes on the Sword Form's DenKamen resemble two halves of a peach, the fruit associated with the story of Momotarō, the Peach Boy, upon which Sword Form is based.[2]

Rod Form[edit]

Rod Form (ロッドフォーム Roddo Fōmu?) is Kamen Rider Den-O's second form, used when Ryotaro is possessed by Urataros. In Rod Form, the DenGasher is transformed into a rod-style weapon. Rod Form gains the ability to move and breathe underwater, increased protection, and increased kicking power. But as a drawback, he loses physical strength and jumping height. Urataros himself assumed this form when he borrowed Ryotaro's Belt to fight off the Mole Imagin he tricked, and again during "Final Countdown" to fight the army of revived Imagin. This form is one of the least used of Den-O's forms, as Urataros rarely fights. However, whenever a fight occurs in the proximity of water, or if the other Imagin are unable to fight, Urataros will assist with his fishing skills. Rod Form is also one of two forms that uses a Rider Kick as part of its standard finisher, pinning the enemy with the rod as a harpoon before executing a flying side kick. The Aura Armor and DenKamen resembles a sea turtle, the animal associated with the legend of Urashima Tarō, upon which Rod Form is based.[3]

Ax Form[edit]

Ax Form (アックスフォーム Akkusu Fōmu?) is Kamen Rider Den-O's third form, used when Ryotaro is possessed by Kintaros. In Axe Form, the DenGasher is transformed into an ax for short, close ranged attacks. Ax Form gains increased strength and defense, but as a result suffers with less speed and kicking power. This form is the physically strongest of the Den-O forms, due to Kintaros's own brute strength. Kintaros himself assumes this form by using the Den-O Belt to help Ryotaro fend off an army of Imagin in the past, and again during "Final Countdown" to fight off the army of revived Imagin. Kintaros tends to fight as Ax Form whenever he senses crying or he hears someone near Ryotaro say anything resembling the Japanese word for "cry" (泣く naku?). Ax Form's Aura Armor is golden yellow and the motif is that of an ax, both symbols prevalent in the story of Kintarō, the Golden Boy, upon which Ax Form is based. The DenKamen is also shaped like the Kanji for the word "gold" ( kin?).[4]

Gun Form[edit]

Gun Form (ガンフォーム Gan Fōmu?) is Kamen Rider Den-O's fourth form, used when Ryotaro is possessed by Ryutaros. In Gun Form, the DenGasher is transformed into a gun for short and long range attacks. Gun Form displays an increase in speed, power, and defense, easily making it the most superior of the four basic forms. Ryutaros tends to fight as Gun Form at his whim, as he is able to overpower the other three Tarōs and in some cases Ryotaro. However, he also tends to cause more damage than the other forms because of his low precision and the high power of his ammunition. Ryutaros himself once assumed Gun Form during the events of "Final Countdown" in order to battle the revived army of Imagin. Ryutaros incorporates break-dancing moves into his fighting style in Gun Form, making his movements somewhat unpredictable. The motif of Gun Form is that of a dragon, the creature associated with the story of Tatsu no Ko Tarō, Tarō the Dragon Boy, upon which Gun Form is based.[5]

Wing Form[edit]

Wing Form (ウイングフォーム Uingu Fōmu?) is Den-O's fifth form, used when Ryotaro is possessed by Sieg, first used by W-Ryotaro to protect Shiori Takayama from the Scorpion Imagin, though it is unable to finish the fight due to Sieg's dwindling strength. Wing Form is used again during the trip to the Edo period to fight the Cobra Imagin. Sieg himself once assumed Wing Form during the events of "Final Countdown" to assist in fighting Shiro's army of revived Imagin. Den-O Wing Form uses the DenGasher as two separate weapons, a boomerang (Sword and Grip) and a handaxe (Ax and Gun). Although it resembles Sword Form, the Aura Skin becomes gold, different shoulders are used, and the DenKamen's visor is blue swan-like wings, associated with the bird of the story of Swan Lake, upon which Wing Form is based (the transformation itself appears as if a swan had landed in front of Den-O's face). In order to access Wing Form, the golden Wing Buckle (ウイングバックル Uingu Bakkuru?) must be placed over the Terminal Buckle.[6] This form gives Den-O far greater agility than Gun Form.[7]

Climax Form[edit]

Climax Form (クライマックスフォーム Kuraimakkusu Fōmu?) is Den-O's sixth form. It is accessed when all of the Tarōs except Momotaros fade away and Ryotaro's desire not to lose them creates the K-Taros which restores the three Imagin's bond to Ryotaro. After entering the code 3-6-9-# and attaching it to the Den-O Belt, Den-O becomes Climax Form. Climax Form is basically a stronger version of Sword Form that incorporates the DenKamen of the other three Den-O forms onto various parts of the armor (Rod Form's DenKamen is on the right shoulder with Urataros controlling the right arm, Ax Form's DenKamen on the left shoulder with Kintaros controlling the left arm, and Gun Form's DenKamen on the chest with Ryutaros controlling the legs). But due to the nature of Climax Form, the Tarōs need to work as one to fight, and their strengths are incorporated into Climax Form. The three DenKamen can also travel along tracks on Climax Form's body to align with the leg or arm to enter Kick Mode (キックモード Kikku Mōdo?) or Punch Mode (パンチモード Panchi Mōdo?), with the three Tarōs controlling that one limb while leaving Momotaros to control the rest of the body to perform "Charge and Up" attacks.[8][9][10][11][12] Usually Momotaros is the one controlling the whole body, but the other Taros are free to take over control of their respective limb parts anytime.

Liner Form[edit]

Liner Form (ライナーフォーム Rainā Fōmu?) is Den-O's final form in the series, gained when the Tarōs created the DenKamen Sword for Ryotaro to use when they could no longer possess him in the past. In order to transform into Liner Form, the Rider Pass must be slid into a slot in the back of the DenKamen Sword's blade. This form, solely controlled by Ryotaro with the Imagin using the DenKamen Sword as a means of communication, is themed around DenLiner Gouka and KingLiner in transformation and attack.[8][13][14] Ryotaro can also utilize each of his Imagin's respective fighting style, whenever their DenKamen is selected on the DenKamen Sword (e.g. 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. Although considerably versatile, Liner Form does not hold any significant strengths or abilities over Den-O's other forms, aside from having the fastest running speed, which sometimes leaves Ryotaro at a disadvantage. The size and weight of the sword also means that it will tire Ryotaro very quickly should he wield it for extended periods. By the time the events of Saraba Kamen Rider Den-O: Final Countdown take place, Liner Form is Ryotaro's default form, accessed through the Rider Pass, the K-Taros, and the Den-O Belt. As compared to before, he could only access Plat Form initially, a sign of his much stronger will.[15]

Super Climax Form[edit]

Super Climax Form (超・クライマックスフォーム Chō Kuraimakkusu Fōmu?), originally known as Kamen Rider Super Den-O (仮面ライダー超・電王 Kamen Raidā Chō Den'ō?), is Den-O's eighth, strongest, 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 Warship.[16] It is identical to the original Climax Form, except with the addition of Sieg's power and Wing Form's DenKamen attaching to back, giving him wings. It is also physically stronger than Climax Form and has the ability to use the wings to fly up and execute a stronger version of Climax Form's Rider Kick. Although the wings are big and powerful to enable actual flight, they are only used to execute the aforementioned Rider Kick.


Den-O Belt[edit]

The Den-O Belt (デンオウベルト Den'ō Beruto?) is Kamen Rider Den-O's transformation belt. It is affixed with a device known as the SetTouch (セタッチ Setacchi?) in the Terminal Buckle (ターミナルバックル Tāminaru Bakkuru?), which can read a Rider Pass (ライダーパス Raidā Pasu?) and the Imagin contained on it. When the Rider Pass is swiped across the SetTouch, a transformation along with multiple form changes can occur. The belt has four buttons (red, blue, yellow, purple), each activating a specific form (Sword, Rod, Ax, Gun), known as the Form Switch (フォームスイッチ Fōmu Suicchi?). It is also used to activate the primary finisher, Full Charge (フルチャージ Furu Chāji?). A variation of the belt, known as the Wing Buckle (ウイングバックル Uingu Bakkuru?), is affixed with a gold winged plate where the Terminal Buckle would normally be and allows for the Wing Form transformation. Any Imagin contracted to a Rider Pass can also use the Den-O Belt to transform into the form they control.[17][18][19][20]

The Den-O Belt with its SetTouch and Rider Pass components are inspired by the electronic smart cards (such as Suica and PASMO) used by Japanese commuters to travel on public transit systems such as trains.


The DenGasher (デンガッシャー Dengasshā?) is modeled after a bullet train and is Den-O's primary weapon. The DenGasher is composed of four separate parts (Sword, Gun, Ax, and Grip) that, when not in use, are attached to the Den-O Belt. Although the weapon configurations are not limited to a specific form of Den-O, there are certain combinations which function best with a corresponding form. Climax Form typically uses it in Sword Mode, although on one exception, he has used one of its other modes (Gun Mode, against the Armadillo Imagin). Liner Form can also use the DenGasher when the Den-Kamen Sword is unavailable. The following listed are the most commonly used ways to form each weapon, but each form also displays various variations in which the weapons are attached in fancy and tricky manners that differ from the norm.

  • For Sword Form, the DenGasher is used in Sword Mode (ソードモード Sōdo Mōdo?). It is formed by combining the Ax and Gun parts, which Momotaros usually lobs into the air, pulling out the Sword and Grip parts, and docking all four together as the joined Ax-Gun portion falls back down. Afterwards, a red blade extends from the top of the sword.[21]
  • For Rod Form, the DenGasher is used in Rod Mode (ロッドモード Roddo Mōdo?). The four parts are linked together in a straight line, one by one - Sword, Gun, Ax, and Grip in that order. Once complete, the DenGasher extends itself until it reaches the size of a regular staff. It can also be used like a fishing rod and a harpoon.[22]
  • For Ax Form, the DenGasher is used in Ax Mode (アックスモード Akkusu Mōdo?). The Grip and Gun parts are stacked on top of each other, creating the handle. The Sword part is then attached to the handle, followed by the Ax part, at which point the blade then extends and expands.[23]
  • For Gun Form, the DenGasher is used in Gun Mode (ガンモード Gan Mōdo?). The Gun part is tossed in the air. Then, the Sword and Ax parts are stacked on top of each other. The Grip part is attached to the bottom of this, while the Gun part falls into place, forming the barrel.[24]
  • For Wing Form, the DenGasher has two modes, Handaxe Mode (ハンドアックスモード Handoakkusu Mōdo?) and Boomerang Mode (ブーメランモード Būmeran Mōdo?), in which two pieces each are used for each weapon. The Sword and Grip parts form the Boomerang and the Ax and Gun parts form the Handaxe.[25]

Full Charge[edit]

Den-O has five different Full Charge (フルチャージ Furu Chāji?) finishing moves, one for each form seen in the television series except for Plat Form. A Full Charge is started by swiping the Rider Pass across the Terminal Buckle, causing the Belt to charge up energy and transfer it into the Dengasher for a finishing attack. It is possible to increase the power of a Full Charge by swiping the pass multiple times.

  • When in Sword Form, Full Charge is used in conjunction with Extreme Slash (エクストリームスラッシュ Ekusutorīmu Surasshu?). The most common form of this attack consists of the DenGasher's blade detaching and flying at high speeds in mid-air, connected by a stream of energy to the hilt. It follows the path where Den-O slashes, making the attack an effective long-range finisher and a damaging short-range attack (as seen in the first episode, being cut with the stream of energy is apparently not as effective). When maneuvered properly, the detached blade can also lift the target to set up for aerial attacks. Less frequently, the Extreme Slash is manifested as simply a regular sword slash imbued with energy.
  • When in Rod Form, Full Charge is used in conjunction with Solid Attack (ソリッドアタック Soriddo Atakku?), a technique where the DenGasher is thrown at the enemy like a spear. Once it hits and penetrates, a blue hexagon shaped barrier called an Aura Cast (オーラキャスト Ōra Kyasuto?), similar to a turtle shell, is created, binding the foe. Den-O then performs the Rider Kick called the Den-Rider Kick (デンライダーキック Denraidā Kikku?), aiming at the center of the target. When Urataros himself assumed Rod Form, he performed a rising side kick to the target as it falls to him. In Final Countdown, Urataros generates a much larger Aura Cast which binds several Imagin and allows him to attack all of them with a single Den-Rider Kick.
  • When in Ax Form, Full Charge is used in conjunction with Dynamic Chop (ダイナミックチョップ Dainamikku Choppu?), a technique where Den-O tosses the DenGasher into the air, jumping in the air after it. After catching it, he brings the axe crashing down on his opponent. When Kintaros himself assumed Ax Form, he performed an alternate variation that used a powerful spinning axe chop on his surrounding targets. In both variations, Kintaros notably says the name only after executing the attack. In one case however he said the name before executing the attack.
  • When in Gun Form, Full Charge is used in conjunction with Wild Shot (ワイルドショット Wairudo Shotto?), a technique where Den-O shoots a powerful ball of energy charged from the DenGasher and the 'dragon orbs' designed in Gun Form's breastplate. Wild Shot can be used in conjunction with Ikazuchi, creating a more powerful stream of energy along with Ikazuchi's blast.
  • When in Wing Form, Full Charge is used in conjunction with Royal Smash (ロイヤルスマッシュ Roiyaru Sumasshu?) where the Boomerang and Handaxe are used in a combination attack. With the Boomerang in mid-air, the Handaxe flies from Den-O's hand to the target for a pincer attack with the Boomerang. The target receives additional damage when Den-O removes the Handaxe from its body. The attack is used slightly differently in Final Countdown, where Den-O throws both Handaxe and Boomerang at the same time.
  • When in Liner Form, Full Charge is used in conjunction with Extreme Slash (エクストリームスラッシュ Ekusutorīmu Surasshu?), identically to Sword Form. It is usually neglected in favor of an AuraLiner finisher unless the DenKamen Sword is not available.


The K-Taros (ケータロス Kētarosu?) is a special cellphone that was formed from the sandy remains of the Tarōs upon reacting to Ryotaro's feelings. Each of the buttons on the keypad correlate to a phrase that allows Ryotaro to call up one of Tarōs. Once attached to the Den-O Belt and the code 3-6-9-# is entered, Den-O can transform into Climax Form. The K-Taros can also summon the DenKamen Sword to evoke Liner Form.[10] It can also be used as a normal cell phone, often being used to communicate with the DenLiner crew.[26]

  • 3-2-1 spells "Momo-Taro-S" (モモ-タロ-ス Momo-Taro-Su?)
  • 6-5-4 spells "Ura-Taro-S" (ウラ-タロ-ス Ura-Taro-Su?)
  • 9-8-7 spells "Kin-Taro-S" (キン-タロ-ス Kin-Taro-Su?)
  • #-0-* spells "Ryu-Taro-S" (リュウ-タロ-ス Ryū-Taro-Su?)
  • 3-6-9-# spells "Momo-Ura-Kin-Ryu" (モモ-ウラ-キン-リュウ Momo-Ura-Kin-Ryū?). This code allows for Den-O to become Climax Form.

Charge and Up[edit]

Charge and Up (チャージアンドアップ Chāji Ando Appu?) is the finisher for Climax Form, accessed similarly to Full Charge by swiping the opened Rider Pass across the Terminal Buckle, allowing for the execution of a final attack.

  • In Kick Mode, Climax Form can use the Rider Kick called the Boistous Kick (ボイスターズキック Boisutāzu Kikku?, "Boisterous Kick" on the TV Asahi website) where Rod Form's mask is at the foot, and two blades extend down along the leg in the kick. Den-O then executes a one hit bicycle kick to the target.
    • While in Super Climax Form, Den-O leaps into the sky as he sprouts energy wings from his Wing Form mask, descending at his opponent while executing a stronger version of his Boistous Kick attack called Super Boistous Kick (超・ボイスターズキック Chō Boisutāzu Kikku?).
  • In Punch Mode, Climax Form can use Boistous Punch (ボイスターズパンチ Boisutāzu Panchi?, "Boisterous Punch" on the TV Asahi website) where Ax Form's mask is at the fist, and the blade that is part of its mask is used in the punch.
  • Climax Form can use Boistous Shout (ボイスターズシャウト Boisutāzu Shauto?) where Gun Form's mask opens like a mouth and releases several homing missiles at the enemy.
  • With the DenGasher in Sword Mode, Climax Form can perform the Extreme Slash. Momotaros refers this as "My Finishing Attack, Climax Version" (俺の必殺技クライマックスバージョン Ore no hissatsu waza kuraimakkusu bājon?) and "Our Finishing Attack, Climax Version" (俺達の必殺技クライマックスバージョン Oretachi no hissatsu waza kuraimakkusu bājon?) in reference to the Taros working together. The attack is similar to the normal Full Charge Extreme Slash, the most noticeable difference being the rainbow-colored hue the blade takes upon being charged. This attack is sometimes referred to as the Boistous Slash (ボイスターズスラッシュ Boisutāzu Surasshu?).

DenKamen Sword[edit]

DenKamen Sword (デンカメンソード DenKamen Sōdo?) is a weapon in the shape of a broadsword with a blade in the shape of a clock hand, created by the Tarōs for Ryotaro, serving as a means of communication from the DenLiner. Once the Rider Pass is inserted into it, Den-O assumes Liner Form to use the sword's full power. The Turntable hilt has the four masks of Sword, Rod, Ax, and Gun Forms. The Turntable spins by pulling the Delta Lever, and the Tarōs can speak through the sword when the respective mask is spun to the blade side. The default mode is Momo-Sword (モモソード Momosōdo?), while the other three settings are Ura-Rod (ウラロッド Uraroddo?), Kin-Ax (キンアックス Kin'akkusu?), and Ryu-Gun (リュウガン Ryūgan?). The DenKamen Sword allows Ryotaro to use one of five finishing attacks, performing a different rushing attack on a set of energy tracks with the silhouette named the AuraLiner (オーラライナー Ōrarainā?) of the mode's respective train car covering him. Ryotaro dubs these five attacks the Train Slash (電車斬り Densha Giri?).[27][28]

  • In Momo-Sword Mode, Den-O performs a powerful horizontal slash through the target with Gouka's AuraLiner covering him named the DenKamen Slash (デンカメンスラッシュ DenKamen Surasshu?).
  • In Ura-Rod Mode, Den-O executes a forward lunging stab with Isurugi's AuraLiner covering him named the DenKamen Attack (デンカメンアタック DenKamen Atakku?).
  • In Kin-Ax Mode, Den-O executes a forward bashing with Rekkou's AuraLiner covering him named the DenKamen Chop (デンカメンチョップ DenKamen Choppu?). This attack was the only finisher not demonstrated throughout the course of the show.
  • In Ryu-Gun Mode, Den-O utilizes a projectile thrust attack at the target with Ikazuchi's AuraLiner covering him named the DenKamen Shot (デンカメンショット DenKamen Shotto?). A variation of this move involves Den-O using the DenKamen Sword as a gun, firing multiple purple beam projectiles to multiple targets.
  • By spinning the Turntable several complete rotations, the symbol in the center charges up and Ryotaro performs the Fullthrottle Break (フルスロットルブレイク Furu Surottoru Bureiku?), with AuraLiners of all four trains flanking him on either side.


The Machine Den-Bird (マシンデンバード Mashin Denbādo?) is Den-O's personal Honda XR250 bike that is able to launch from the DenLiner. Although Ryotaro never uses it as a mean of transportation, the Imagin would sometimes use it while possessing his body. While docked in the DenLiner, it serves as the control mechanism for the train. When a Rider Pass, along with a Rider Ticket, is inserted into the Den-Bird while it is docked in the DenLiner, the date on the ticket becomes DenLiner's destination. During the fight with the Oct Imagin, the bike is sabotaged by the enemy and turns against Den-O. Though it burst into flames, the Den-Bird was later repaired or replaced fast enough to be used against the rampaging time-tracks under the control of the Oct Imagin's remains.[29]


The DenLiner (デンライナー Denrainā?) is Den-O's transportation system, a bullet train mainly used for traveling to other times and launching attacks against Gigadeaths. The DenLiner arrives when a person holding a Rider Pass touches a door while the hour, minute and second of time are the same. It is able to travel to different times when a Rider Pass, along with a Rider Ticket that contains the date in which an Imagin has traveled to, is inserted into the DenBird, while docked in the DenLiner. The date then becomes the DenLiner's new destination in time.

The DenLiner has multiple forms, split throughout eight cars. When not using a certain form, the DenLiner's eight cars are linked up, forming one large train. These railroad cars only disconnect and change form when Den-O is in the corresponding form. Form-specific cars can also link up with other cars in various orders to provide additional weaponry when fighting Gigandeaths. Furthermore, the DenLiner can link up with the ZeroLiner for more power. When Den-O enters Climax Form, the DenLiner is affected by the power surge and enters Climax Mode (クライマックスモード Kuraimakkusu Mōdo?), turning a golden color with an intense fiery aura around it.

The DenLiner also has various non-combative cars that separate from the Gouka during battle and serve as settings for the television series and movies. These include the dining car where most of the series takes place, a bath car used several times late in the series, and the sleeping car where the group meets the Swan Imagin Sieg.


DenLiner Gouka (デンライナー ゴウカ(業火) Denrainā Gōka?) is based on the legend of Momotarō and is activated when Den-O is in Sword Form. This train is composed of cars one through four, each with a unique attack that relates to a component of the legend. When attacking, the train turns sideways and each of the four compartments open up, each revealing a weapon.[30]

  • The first car is the GouCannon (ゴウカノン Gōkanon?). It represents Momotarō himself and is able to fire lasers.
  • The second car is the Doggy Launcher (ドギーランチャー Dogī Ranchā?). It represents the dog Momotarō befriends and is able to fire rockets named Doggy Bark (ドギーバーク Dogī Bāku?).
  • The third car is the Monkey Bomber (モンキーボマー Monkī Bomā?). It represents the monkey Momotarō met and is able to launch bombs named Monkey Bomb (モンキーボム Monkī Bomu?).
  • The fourth car contains the Birdie Missile (バーディーミサイル Bādī Misairu?) that represents the pheasant that Momotarō met. It is a miniature bird with blade-like wings.


DenLiner Isurugi (デンライナー イスルギ(石動) Denrainā Isurugi?) is a turtle-style train that is activated when Den-O is in Rod Form. Composed of car five, the back of the car is able to open to release a turtle-like machine named Radome (レドーム Redōmu?) that Den-O uses as a hovercraft to travel on water. Isurugi is also able to fire lasers from its front. Isurugi can also combine with Gouka, but instead of staying in the back, it attaches to the front. In addition to Gouka's usual weaponry, Radome sits on top Isurugi, extending two blade-like lasers when attacking, chopping a Gigandeath in half.[31]


DenLiner Rekkou (デンライナー レッコウ(裂光) Denrainā Rekkō?) is an ax-style train that is activated when Den-O is in Ax Form. Composed of car six, five axes called the Side Ax (サイドアックス Saido Akkusu?) appear from each side of the train along with one large ax called the Front Ax (フロントアックス Furonto Akkusu?) on the head. Rekkou is a primarily close range offensive train. The five axes on the sides can strike through the Gigandeath with the whole train facing upward, chopping through the enemy multiple times, or hold the monster at bay to deliver a piledriver attack. Its most effective attack is when Rekkou's large ax on the front expands in length and Rekkou passes under the Gigandeath at full speed, slicing the target in half. It is also able to combine with Gouka, attaching to the front, which allows their weaponry to be combined. When combined with Ikazuchi, its axes on the side can create crescent waves shot at the Gigandeath.[32]


DenLiner Ikazuchi (デンライナー イカヅチ(電雷) Denrainā Ikazuchi?) is a dragon-style train that is activated when Den-O is in Gun Form. Composed of cars seven and eight, the upper half is able to open up to reveal a dragon head while the rear half is able to reveal a dragon tail. The dragon's head is able to launch energy blasts and bite into Gigandeaths to fling them away. It is able to combine with all the other trains, forming a new DenLiner that contains eight cars, all in their respective forms. Ikazuchi's first car with the dragon head is in front, followed by Rekkou, Isurugi, Gouka. The end is the second part of the Ikazuchi, with the dragon tail (the Kanji names of these cars spell out "Lightning Speed" (電光石火 Denkōsekka?)). Unlike other formations, Den-O stays atop of the dragon head with the Machine DenBird when fighting (in other formations, Den-O operates from within Gouka), performing a conjunction attack with a variation of his Wild Shot and a powerful bursting stream of energy from Ikazuchi's cannon.[33]


The KingLiner (キングライナー Kingurainā?) is one of a set of giant red train-car-like structures composing the Time Station, which appears whenever there is a future junction formed. Normally, a KingLiner is in Station Mode (ステーションモード Sutēshon Mōdo?), with a train track inside of it for smaller time trains to connect. But, whenever a time-train is in crisis, the KingLiner pinpoints the exact location and assumes Liner Mode (ライナーモード Rainā Mōdo?) to become a mobile time-train to aid the train in question. In this state, the KingLiner can use the King Launcher (キングランチャー Kingu Ranchā?) to attack and the King Fire (キングファイア Kingu Faia?) to rocket-propel itself and brake to a full stop.[34][35]
