This article is about the A.R. World version of Kamen Rider Kuuga. For the original Kamen Rider Kuuga, see Yusuke Godai
"This man is fighting so that no one else need to fight. Even when plunged alone in his darkness, he wants to make others smile. That what he believes! If he protects smiles, then I will protect his smile! Did you know? His smile is not bad."
Tsukasa talking about Yusuke to N-Gamio-Zeda[src]

Yusuke Onodera (小野寺 ユウスケ Onodera Yusuke?) is the resident Kamen Rider Kuuga of the World of Kuuga in Kamen Rider Decade. He has a very self-confident and gullible child-like personality, a stark contrast to the original incarnation of Kuuga, Yusuke Godai.

Yusuke supports the police in fighting the Gurongi and has feelings for Detective Ai Yashiro, as he fights to see her smile. When Yusuke first discovered the Arcle Belt, he was warned of Decade's existence as the "devil" by Narutaki.

Yusuke rarely engages in battle while journeying with Tsukasa. He does, however, act as a inspirational figure to the other Riders, as can be seen with his aiding of Wataru, as well as his actions in the other Riders' worlds. While traveling with Tsukasa, he acts as his personal assistant.

Fictional character biographyEdit

After killing the Gurongi Me-Gyarido-Gi and Ra-Dorudo-Gu, Yusuke answers Ai's call about another Gurongi being spotted. After witnessing Decade defeat another Gurongi, Ai and Yusuke meet Tsukasa, who offers them his help as a policeman. Although Yusuke seems to be annoyed by this, Tsukasa demonstrates his intellect and baits out two Gurongi. Yusuke recognizes Tsukasa transforming into Decade, the man who will defeat all the riders, and attacks him, but their battle is interrupted by Kick Hopper and Punch Hopper appearing due to a dimensional rift.

After the battle, Tsukasa goes off to a fight a revived N-Gamio-Zeda who is terrorizing the city by converting humans into Gurongi using his miasma. Yusuke saves Ai from the miasma, but is afraid to fight because she is dying. Her words are able to convince him otherwise, and Yusuke, along with Tsukasa, defeats Gamio. However, upon his return, Yusuke finds that Ai has died. Yusuke promises to go on fighting, in order to protect everyone else's smile.

But after visiting Ai's tombstone to pay his respects, Yusuke meets Kivala who brings him to Castle Doran in Kiva's World, where Yusuke offers his aid to the Fangire King Wataru before joining Tsukasa's group as a resident of Hikari Photo Studio.

However during the Rider War, though his world is destroyed, Yusuke still exists due to his traveling of the Nine Worlds. Even though he is destroyed by Decade in The Last Story, he and his world are restored, allowing him to aid in reviving Decade and defeating the newly formed Super Shocker once and for all.

Later appearancesEdit

Movie War 2010 currently remains the last on-screen appearance of Yusuke Onodera. The Kuuga that appears in OOO, Den-O, All Riders: Let's Go Kamen Riders and Kamen Rider × Super Sentai: Super Hero Taisen is the original Kuuga, Yusuke Godai.

Video Game AppearancesEdit

Kamen Rider Battride WarEdit

Although the playable Kuuga in Kamen Rider Battride War is confirmed to be Yusuke Godai, Yusuke Onodera makes an unofficial appearance in one mission and is directly referenced in another. In the mission Decade's Awakening, the first "boss" character fought is Kuuga, intended to represent Onodera (though there are no gameplay or vocal changes from the normal Godai version). Additionally, if the player uses Decade in the mission Kuuga's Awakening, Tsukasa will have special dialog where he acknowledges that Godai isn't the same man he traveled with, but says they both have the same desire to protect people's smiles and encourages Godai to remember that desire to help him break free of Mnemosyne. However, Kuuga cannot be used in Decade's Awakening due to the presence of the boss Kuuga, meaning Godai has no special dialog with Tsukasa.

Kamen Rider Kuuga (and other Rider Powers)Edit

Just like the original Kamen Rider Kuuga, Kuuga can change into various forms into which he gains different powers and specialties. The forms Yusuke Onodera has transformed into are Mighty Form (マイティフォーム Maiti Fōmu?), Dragon Form (ドラゴンフォーム Doragon Fōmu?), Pegasus Form (ペガサスフォーム Pegasasu Fōmu?), Titan Form (タイタンフォーム Taitan Fōmu?), and Growing Form (グローイングフォーム Gurōingu Fōmu?) when defeated.

In Natsumi's dream, showing the events to come in the Rider War, Kuuga assumes Ultimate Form (アルティメットフォーム Arutimetto Fōmu?) when he fights Decade one-on-one. However, this form is in the original black-eyed instead of red-eyed, revealed to be the result of Yusuke losing control over his attacks when infused with Demon Imperial Powers (魔皇力 Maōryoku?) by Kivala's bite. This carries on into the events of Movie War 2010, where Kuuga transforms into Ultimate Form to fight Decade Violent Emotion.

However, outside of his home A.R. World and the Rider War dream, Yusuke has mostly used Mighty Form, transforming once into Titan Form while in the World of Amazon to destroy a Propheta Cruentus and Dragon Form once in the World of Decade to fight Keisuke Jin (Kamen Rider X). In the World of Agito, Yusuke dons the Kamen Rider G3-X (仮面ライダーG3-X Kamen Raidā Jī Surī Ekkusu?) suit for a while. During the visit to the world of Den-O, Yusuke is possessed by Momotaros, who uses him as a body to transform into Kamen Rider Den-O Sword Form (仮面ライダー電王 ソードフォーム Kamen Raidā Den'ō Sōdo Fōmu?).

While he can transform into Rising Ultimate (ライジングアルティメット Raijingu Arutimetto?) that Yusuke Godai did not access (until the 53rd/final episode of Kamen Rider Wizard), Onodera has not been seen using the Rising versions of his four basic forms, Rising Mighty (ライジングマイティ Raijingu Maiti?), which Godai further advanced to Amazing Mighty (アメイジングマイティ Ameijingu Maiti?), Rising Dragon (ライジングドラゴン Raijingu Doragon?), Rising Pegasus (ライジングペガサス Raijingu Pegasasu?), and Rising Titan (ライジングタイタン Raijingu Taitan?).

Growing Form

Growing Form

  • Rider height: 190cm (6ft 2in)
  • Rider weight: 90kg (198.4lbs)

Growing Form (グローイングフォーム Gurōingu Fōmu?) is the weakest form of Kuuga and has white armor with small horns. It was only seen in a blink-and-miss moment in episode 3 of Kamen Rider Decade, after he took a powerful blow from N Gamio Zeda. A big difference between this Growing Form and Godai's Growing Form is that he is able to transform without having to wait two hours. Although his power is weak in this form, he can still use the finisher called "Growing Kick" (グローイングキック Gurōingu Kikku?), though it is only 1/3 as strong as the Mighty Kick.

Mighty Form
Kamen Rider Kuuga (World of Kuuga)

Mighty Form

  • Rider height: 200 cm. (6 ft., 5 in.)
  • Rider weight: 99 kg. (218.2 lbs.)
  • Ability perimeters:
    • Punching power: 3 t.
    • Normal kicking power: 10 t.
    • Maximum jump height: 15 m. (49 ft., 2 in.)
    • Maximum running speed: 100 m. per 5.2 seconds (328 ft. per 5.2 sec)
    • Sense: x10
    • Finishing Attack Power: 30 t. (Mighty Kick)

Mighty Form (マイティフォーム Maiti Fōmu?) is Kuuga's default form and has red armor, referred to by the police as Unidentified Life Form #4. Yusuke was first able to transform into this form while fighting Zu-Gooma-Gu. In this form, Kuuga uses his "Mighty Kick" (マイティキック Maiti Kikku?) attack to kill the monsters.

Dragon Form

Dragon Form

  • Rider height: 200 cm. (6 ft., 5 in.)
  • Rider weight: 90 kg. (198.4 lbs.)
  • Ability perimeters
    • Punching power: 1 t.
    • Normal kicking power: 3 t.
    • Maximum jump height: 30 m. (98 ft., 4 in.)
    • Maximum running speed: 100 m. per 2 seconds (328 ft. per 2 sec)
    • Sense: x10

Dragon Form (ドラゴンフォーム Doragon Fōmu?) is a azure form form that allows Kuuga to be more agile and quicker, although his physical strength is lower than Mighty Form, Dragon Form enables Kuuga to and jump quickly in order to pursue the enemy. However, it also gives Kuuga less protection, yet being better suited for quick movements and more jump power. To make up for the lack of strength, he uses the Dragon Rod (ドラゴンロッド Doragon Roddo?) staff as his weapon, transmorgified by using any pole or stick-like object to manifest it. His finishing move in this form is Splash Dragon (スプラッシュドラゴン Supurasshu Doragon?), an aerial thrust attack to the torso.

Pegasus Form

Pegasus Form

  • Rider height: 200 cm. (6ft., 5in.)
  • Rider weight: 99 kg. (218.2lbs.)
  • Ability perimeters
    • Punching power: 1 t.
    • Normal kicking power: 3 t.
    • Maximum jump height: 15 m. (164 ft.)
    • Maximum running speed: 100 m. per 5.2 seconds (328 ft. per 5.2 seconds)
    • Senses: x1,000

Pegasus Form (ペガサスフォーム Pegasasu Fōmu?) is a green shooting form where Kuuga's senses are heightened to extreme, superhuman levels, enabling him to see, hit and hear his opponents with deadly precision. It also allows Kuuga to detect the enemy's position, despite whatever ability they may have to avoid detection. The downside to this is that it can not be sustained for too long because of the enormous strain placed on the nervous system from over stimulation (only 50 seconds), and if Kuuga exceeds this limit, he shall be knocked back into Growing Form and become unable to transform for two hours. Kuuga uses the Pegasus Bowgun (ペガサスボウガン Pegasasu Bōgan?) crossbow/gun hybrid weapon that can be created out of any gun-like object, commonly Ai's hand gun. His finishing move with the bow gun is "Blast Pegasus" (ブラストペガサス Burasuto Pegasasu?), an arrow shot from the bowgun after pulling the hammer back to the fullest length.

Titan Form

Titan Form

  • Rider height: 200 cm. (6 ft., 5 in.)
  • Rider weight: 110 kg. (242.5 lbs.)
  • Ability perimeters
    • Punching power: 7 t.
    • Normal kicking power: 10 t.
    • Maximum jump height: 10 m. (32 ft. and 8 in.)
    • Maximum running speed: 100m per 7.2 seconds (328 ft. per 7.2 seconds)
    • Sense: x10

Titan Form (タイタンフォーム Taitan Fōmu?) is a purple herculean form where his defense is greatly increased, allowing him to withstand most of his opponents' attacks long enough to get in close range, despite sacrificing speed. This form has much larger armor that is mainly silver with large purple trims. Although this armor provides superior protection, it still leaves parts of his body exposed, thus making him still susceptible to damage. He uses the Titan Sword (タイタンソード Taitan Sōdo?) that can be created out of pole or stick-like objects, or in one occasion, the sword of a fallen Gurongi. His finishing move is "Calamity Titan" (カラミティタイタン Karamiti Taitan?), a powerful sword thrust wherein Kuuga twists the blade as it is impaled.

Ultimate Form

Ultimate Form
(Red Eyes)

Ultimate form0

Ultimate Form
(Black Eyes)

  • Rider height: 200 cm. (6 ft., 5 in.)
  • Rider weight: 150 kg. (330.6 lbs.)
  • Ability perimeters
    • Punching power: 80 t.
    • Normal kicking power: 100 t.
    • Maximum jump height: 50 m. (164 ft.)
    • Maximum running speed: 100 m. per 2 seconds (328 ft per 2 seconds)
    • Sense: x10,000

His most dangerous form, Ultimate Form (アルティメットフォーム Arutimetto Fōmu?) combines all the powers of the other forms, Ultmate Kuuga has a much different design colored black with gold (and a little silver) trims all over his body, as well as having five horns on the headcrest, a black belt core and spiky-looking armor.

Yusuke assumes Ultimate Form when he fights Decade one-on-one. However, this form is black-eyed instead of red-eyed, revealed to be the result of Yusuke losing control over his attacks when infused with Demon Imperial Powers (魔皇力 Maōryoku?) by Kivala's bite.

This form can also utilize the powers including Pyrokinesis, along with the ability to utilize the Dragon Rod, Pegasus Bowgun, and Titan Sword, all in Rising form. However this ability was never shown along with the Ultimate Form's most powerful attack, the "Ultimate Kick" (アルティメットキック Arutimetto Kikku?), which is the strongest version of his Rider Kick, easily capable of destroying the entire world. In Kamen Rider Decade, Ultimate Kuuga is also capable of the Ultimate Punch (アルティメットパンチ Arutimetto Panchi?) finisher, a punch coated with hot flames. This form was also called the Supreme Warrior (最高戦士 Saikō Senshi?).

Rising Ultimate
Kamen Rider Kuuga Rising Ultimate Form

Rising Ultimate


Rising Ultimate
(Black & Red Eyes)

  • Rider height: 200 cm. (6 ft., 5 in.)
  • Rider weight: 150 kg. (330.6 lbs.)
  • Ability perimeters
    • Punching power: 100 t
    • Normal kicking power: 120 t.
    • Maximum jump height: 110 m. (360.8 ft.)
    • Maximum running speed: 100 m. per 1 seconds (328 ft per 1 seconds)

Unique to Kamen Rider Decade is Kuuga Rising Ultimate (ライジングアルティメット Raijingu Arutimetto?). Much like Kuuga's other forms that were given a "Rising" upgrade within the original Kamen Rider Kuuga, Rising Ultimate is an advanced version of Kuuga's Ultimate Form. In this form, Kuuga has two attacks: the Rising Ultimate Mighty Kick (ライジングアルティメットマイティキック Raijingu Arutimetto Maiti Kikku?) and the flaming Rising Ultimate Mighty Punch (ライジングアルティメットマイティパンチ Raijingu Arutimetto Maiti Panchi?). Rising Ultimate Kuuga is first accessed in Kamen Rider Decade: All Riders vs. Dai-Shocker after Yusuke has been attacked by the Stone of Earth used by High Priestess Bishium, putting him under her control and unleashing all of Kuuga's potential. When Kuuga is under controlled of Bishium, Kuuga's eyes become the Dark Eyes (ダークアイ Dāku Ai?), and when Kuuga is freed of Bishium's control, the eyes change color from the Dark Eyes to the Red Eyes (レッドアイ Reddo Ai?). He later uses this form again in Kamen Rider × Kamen Rider W & Decade: Movie War 2010 to fight Doras thanks to Decade's K-Touch.

Kuuga Gouram
"Final Form Ride: Ku Ku Ku Kuuga!"
―Transformation announcement[src]
KRD-Kuuga Gouram

Kuuga Gouram

Decade's Final Form Ride Card allows Kuuga to transform into the Kuuga Gouram (クウガゴウラム Kūga Gōramu?), giving him the ability to fly. This form is used again in the World of Den-O to assist Decade and Den-O and allowing Momotaros to execute the Decade Liner (ディケイドライナー Dikeido Rainā?) Final Attack Ride. The Kuuga Gouram rushes toward Decade with the target stuck in his pincers while Decade performs the Mighty Kick-like Decade Assault (ディケイドアサルト Dikeido Asaruto?)[1][2] attack towards the target. After the card is used, Kuuga can change into this form at will before Decade uses the Kuuga Final Attack Ride Card.[3]

In Kamen Rider × Kamen Rider W & Decade: Movie War 2010, Kamen Rider Kuuga shows the ability to transform into the Kuuga Gouram without Kamen Rider Decade using the Final Form Ride Card.

Ultimate Kuuga Gouram

Ultimate Kuuga Gouram

In Kamen Rider × Kamen Rider W & Decade: Movie War 2010, Kamen Rider Kuuga Ultimate Form transforms into the Ultimate Kuuga Gouram (アルティメットクウガゴウラム Arutimetto Kūga Gōramu?), a more powerful version of the Kuuga Gouram, to fight Kamen Rider Decade Violent Emotion. However, he is soon defeated and becomes a Kamen Ride card for Decade but appears again when Decade uses the All Rider Final Form Ride Card to fight the Super Crisis Fortress. The Ultimate Kuuga Gouram can execute the Ultimate Assault (アルティメットアサルト Arutimetto Asaruto?), by crushing the enemy in its pincers and rushing towards a hard surface. The Ultimate Kuuga Gouram is similar to the Kuuga Gouram, though it has the color scheme and the head crest of Ultimate Form and has Black Eyes.

Decade Dodge

Kuuga Ball

In Kamen Rider Battle: Ganbaride Decade uses the Kuuga Ball (クウガボール Kūga Bōru?) card to change Kuuga into a dodgeball-like form to perform the Decade Dodge (ディケイドドッジ Dikeido Dojji?) attack.

Kamen Rider G3-X

Kamen Rider G3-X

In the World of Agito, Yusuke dons the Kamen Rider G3-X (仮面ライダーG3-X Kamen Raidā Jī Surī Ekkusu?) suit for a while.

  • Height: 192cm
  • Weight: 176kg
  • Puching Power: 2.5t
  • Kicking Power: 7.5t
  • Highest Jump: 20m
  • Top Speed: 100m/8s
  • Vision and Hearing: 15km approx.
  • Defense Rating: 10/10

From what was seen during Shouichi Ashikawa's past, the suit has been modified from an original version of Kamen Rider G3, using the G3's diagnostic data. All specs and performance potentials have been ramped-up. It's unknown if it has the same A.I. problem as the original G3-X, though if the G4 chip is to be any indicator, the G3-X still had something to be modified. It's newest armament, the GX-Launcher (GX-05 Cerberus), can level Grongi (and later, Unknown) with ease.

"Sword Form!"
―Transformation announcement[src]

Kamen Rider Den-O



During the visit to the world of Den-O, Yusuke was possessed by Momotaros, who uses him as a body to transform into Kamen Rider Den-O Sword Form (仮面ライダー電王 ソードフォーム Kamen Raidā Den'ō Sōdo Fōmu?).

  • Height: 190cm
  • Weight: 87kg
  • Punching power: 5t
  • Kicking power: 7t
  • Maximum jump height: 35m
  • Maximum running speed: 100m/5.2s

When possessing Yusuke (or anyone else) or by himself, Momotaros can assume Den-O's Sword Form 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. He occasionally forms different finishers for defeating enemies, despite parts 2, 3, and 5 being similar to each other. He also uses a Special Version in I'm Born which resembles the aforementioned parts, the only difference is that Full Charge is used twice. There is also a Final Version used against the Death Imagin which uses energy from the other Taros, Sieg, and Kamen Rider Zeronos. In the Cho Den-O series Sword Form also has a triple Roundhouse Rider Kick that Momotaros dubs his "Super Finishing Attack." The DenKamen Mask resembles two halves of a peach, which is based on the story of Momotaro.


Yusuke possesses some of the same equipment used within the original Kuuga, such as the Arcle (アークル Ākuru?) transformation belt, and a stone embedded in the belt called Amadam (アマダム Amadamu?) that serves as the source of his power and is able to extend a person's lifespan. He also possesses the TryChaser 2000 (トライチェイサー2000 Torai Cheisā Nisen?), a new model of police motorcycle designed to be faster and more powerful than the average bike.

Behind the scenesEdit


Yusuke Onodera was portrayed by Ryouta Murai (村井 良大 Murai Ryōta?). As Kamen Rider Kuuga, his suit actors were Kenji Tominaga (富永 研司 Tominaga Kenji?) and Norihito Itō (伊藤 教人 Itō Norihito?). In the newly released Kamen Rider Battride War, he was voiced by Nobunaga Shimazaki, who also voices his actual counterpart.



Yusuke's surname Onodera (小野寺?) is a reference to Kamen Rider Series creator Shotaro Ishinomori who's original family name is the same as Yusuke.
