Characters Introduced in Ore, Tanjou!

    Gaoh/Kamen Rider Gaoh 

Gaoh/Kamen Rider Gaoh

Portrayed by: Hiroyuki Watanabe (live), Yoshifumi Oshikawa (suit)
"I will devour everything!"

The Big Bad of the first movie, Gaoh is a thief-king who, along with a gang of rogue Imagin following him, targets time trains. After getting Ryotaro to chase an Imagin to 2000, he stole the DenLiner in order to go further back in time, as well as to obtain the Master Pass from Owner, which allows its user to go to any time period they wish. Upon arriving in the Sengoku period, he manipulates Yukimura Sanada into helping him uncover the GaohLiner, a time train originally named "God's Train" due to its ability to control time, even being able to erase Singularity Points. In the end, Gaoh is brought down by the combined efforts of all four Den-Os (collected from various points in time by Yuto) and Zeronos.

  • BFS: GaohGasher Sword Mode.
  • Big Bad: Of Ore, Tanjou!.
  • Big Eater: Quite literally; Gaoh spends most of his non-battle scenes munching on large quantities of food, such as whole turkey legs or pineapples.
  • Catchphrase: "Everything, I'll devour it all." Japanese 
  • Cool Old Guy: Hiroyuki Watanabe was 51 during filming, making him the oldest actor to portray a Kamen Rider.
  • Death by Genre Savviness: Doesn't wait for Sword Form to finish charging up his Finishing Move, going in for the kill, except that Momo actually anticipated this; at close proximity, Gaoh was left vulnerable to Extreme Slash, Special Version.
  • Finishing Move: Tyrant Crash (similar to Den-O's Extreme Slash).
  • Gang of Hats: His Imagin followers are all reptilian.
  • In the Style of: Double-Action Gaoh Form = Death Rock. Also the only Double-Action variation sung solo.
  • No Body Left Behind: After Den-O kills him he's 'consumed by time' and reduced to sand.
  • No-Holds-Barred Beatdown: His first henshin in order to fight Zeronos can be described as this.
  • Omnicidal Maniac: He wanted to destroy time itself.
  • Palette Swap: The Gaoh costume is built from a Den-O costume, but it's still pretty least until they used it to build Yuuki from the third movie...
  • Single-Stroke Battle: How Den-O finally finishes him.
  • Straw Nihilist: His goal is to destroy all time because he's grown bored of it and considers it pointless.
  • Why Don't Ya Just Shoot Him?: After uncovering the GaohLiner, Gaoh heads to Ryotaro's birthday with the intent of erasing the day from existence, therefore destroying Ryotaro AND Den-O.
  • Villain Song: While he doesn't sing it in the movie itself, Double Action Gaoh Form is added to the director's cut of the movie. His is also the only solo version of the song.

Characters Introduced in Climax Deka

    Kazuya Suzuki 

Kazuya Suzuki

Portrayed by: Ryota Murai

A police detective, Suzuki is assigned to work with the DenLiner Police in order to investigate the rash of Imagin and Fangire-related crimes that have been on the rise lately. Initially he doesn't mesh with the team at all, being freaked out by the Imagin and blindly pursuing the criminal Seiya Kuroki. Eventually they learn that his father Kazuma Suzuki (portrayed by Ryoji Morimoto) was a great policeman and he just wants to live up to his example.

  • Butt-Monkey: His terror of the Imagin and general incompetence leads him to being smacked around and teased constantly, and he's even kidnapped by Negataros' crew.
  • Disappeared Dad: His father was a cop who died on the job when Kazuya was still very young.
  • This Is Something He's Got to Do Himself: Though Hana could kick Kuroki's butt five ways from Sunday, she lets Suzuki collar him, even if it does mean a drawn-out fight where he takes his share of lumps.
  • "Well Done, Son" Guy: His goal is to follow in his father's footsteps. Amusingly, during their trip to 1986 to give Kazuya closure, we hear his father remark that he wants better for his son.
  • What the Hell, Hero?: Momo chews him out for foolishly infiltrating Negataros' HQ without any backup, leading to him getting captured. Granted, it was because the rescue attempt mounted by the DenLiner Police nearly cost them their lives.
    Negataros/Kamen Rider Nega Den-O 

Negataros/Kamen Rider Nega Den-O

Portrayed by: Hikaru Midorikawa (voice), Jiro Okamoto (suit)
"My evil organization is eternal!"

The Big Bad of Climax Deka, Negataros is a rogue Imagin who survived Kai's death and struck out on his own, attempting to found an Evil Organization. In his quest, he recruited human criminals as well as Imagin and Fangire, and eventually drew the DenLiner Police's notice when he stole Owner's spare Rider Pass. In the final battle, he used the Pass to transform into Nega Den-O, but was taken down by the combined efforts of the DenLiner crew and Kamen Rider Kiva.

  • Ascended Extra: Negataros gets a great deal of expansion in Den-O's S.I.C. Hero Saga story, a text series published in Hobby Japan Magazine. The story, an alternate version of Climax Deka, has Negataros travel to 1971 and join forces with Shocker, the evil organization of the original Kamen Rider, which leads Ryotaro and Yuto to pursue and eventually team up with the Showa Kamen Riders.
  • Card-Carrying Villain: He wants to form an "evil syndicate" so he can take over the world; he's not as hammy as most examples, but it's clear he knows he's a villain and revels in being one.
  • Evil Twin: Of Momotaros, as well as Den-O Sword Form.
  • Finishing Move: As Nega Den-O, he can use any of Den-O's primary four finishers, though in Climax Deka we only see the Nega Wild Shot. The arcade game Ganbaride shows the Negastreme Slash, as well as giving Negataros himself a move that combines all four finishers, called Hell's Quartet.
  • The Mafia: What he wants to be, apparently.
  • Orcus on His Throne: Didn't do anything significant, just bragging about his "evil syndicate", at least until the movie's climax.
  • Palette Swap: Almost literally; Negataros is a negative-colored Momotaros, and Nega Den-O is Sword Form painted purple with blue tribal flame-like markings.


Characters Introduced in Final Countdown

    Kotaro Nogami/Kamen Rider New Den-O 

Kotaro Nogami/Kamen Rider New Den-O

Portrayed by: Dori Sakurada (live), Seiji Takaiwa, Makoto Ito (suit)
"My strength is... the real thing."

Ryotaro's Grandkid From The Future. He grew up listening to stories of Ryotaro's exploits from Owner, and eventually became the new Den-O along with his partner Imagin Teddy. The smug, arrogant Kotaro looks down on Ryotaro and the Taros, thinking them to be weak fools who could barely get the job done, and stepping in to take over as the protector of the timeline. However, after fighting alongside the younger Ryotaro and his allies, Kotaro gained an honest respect for his grandfather and mellowed out a good deal.

Voted #3 Kamen Rider in the Kamen Rider Den-O franchise, #59 Kamen Rider in the Heisei era, and #83 Kamen Rider overall in NHK's All Kamen Rider Popularity Vote.

  • Amazingly Embarrassing Parents: His grandfather, Ryotaro, though Kotaro later drops the attitude.
  • Belated Love Epiphany: A non-romantic variation with Teddy; in Episode Blue the Owner takes Teddy's contract away and has him doing chores on the DenLiner, while Kotaro is forced to used the Taros as replacements. He ends up miserable, constantly failing, and he realizes how much he took for granted his partnership with Teddy.
  • Blade on a Stick: DenGasher, Naginata Mode (Vega Form, when Deneb possesses him in Onigashima Battleship).
  • Catchphrase: "My strength is *snaps fingers twice* the real thing.".
  • Character Tics: Snapping his fingers. In Final Countdown, he has Teddy set up a countdown of how long it'll take him to defeat an opponent; as a show of his arrogance it tends to be a low number, always below 30 seconds. The real sign that he's matured is when Teddy asks for a count against Shiro and Kotaro replies "The real battle starts at zero!"
  • Cool Sword:
    • Momotaken (Momotaros in Let's Go Kamen Riders).
    • DenGasher, Sword Mode (Strike Form, when Teddy is fighting alongside him).
  • Defrosting Ice King: In Final Countdown, after being beaten down by the movie's Big Bad, Kotaro becomes sullen and tries to train even harder. Momotaros comes to talk with him about how his grandfather was strong in much the same way (i.e., getting back up after being knocked down.) From then on, Kotaro becomes a lot warmer towards Ryotaro and less arrogant in general.
  • Distressed Dude: His capture at the hands of the Oni is an important part of Onigashima Battleship.
  • Embarrassing First Name: He dislikes it because apparently in the future it gained the connotation of being a "country" name.
  • Epic Flail: Uratazao (Urataros in Episode Blue).
  • Finishing Move:
    • Strike Form:
      • Counter Slash: A Diagonal Cut with the MacheTeddy.
      • Strike Spurt: New Den-O's Rider Kick.
    • Vega Form: Brandish Dive.
  • Hostage for MacGuffin: He's captured by the Oni in Onigashima Battleship and offered in exchange for the DenLiner, as well as the other half of the Oni's Kirifuda that they plan to use to wipe out humanity.
  • Kid from the Future: He's a strange case, seeing as how Ryotaro never had any romantic interests within the series; early press on the Cho Den-O Trilogy implied that his father would appear, but this turned out to be false.
  • Lamarck Was Right: He seems to have inherited Ryotaro's bad luck of all things...
  • Machete Mayhem: MacheTeddy.
  • Morph Weapon: Kotaro has the power to change any Imagin into a weapon for him to usenote .
  • One-Steve Limit: Averted. He isn’t the first Rider to be named Kotaro.
  • Powers via Possession: Averted with Strike Form, but played straight with Vega Form needing Deneb to possess Kotaro.
  • Real Life Writes the Plot: Sort of. One of the big reasons they switched from Ryotaro to Kotaro is because Ryotaro's actor, Takeru Satoh, made it big and Toei couldn't really afford his agency's set salary (despite Takeru always saying that he loved playing Ryotaro). This is also the reason why Takuya Mizoguchi replaced Satoh as Ryotaro from The Onigashima Battleship onwards.
  • Rearrange the Song: Double-Action Strike Form (rock and roll), finally introduced in the Chou Den-O Trilogy.
  • Swiss-Army Weapon: Like his Grandpa, Kotaro has his own DenGasher that can be assembled in any mode.


Portrayed by: Daisuke Ono (voice), Shinichi Kaneda (suit)
Kotaro's partner Imagin, Teddy is quiet, polite, and reserved. Unlike the other heroic Imagin who possess their contractors, he assumes the form of a two-handed sword dubbed the MacheTeddy in order to aid Kotaro in battle. He attempts to subdue Kotaro's brashness, and often ends up apologizing to the DenLiner team after the young man leaves the room. His capture while attempting to spy on Shiro gives the first indication that Kotaro might have a softer side, and the two are friends and partners despite their differing personalities and the master/servant relationship they seem to exhibit.
  • Battle Butler: Teddy assists Kotaro in battle, turning into a sword when they transform. He also fulfills a butler role for him in catering to his needs (even up to protecting Kotaro from his own bad luck.)
  • Belated Love Epiphany: Of a non-romantic sort; after the Owner takes up a contract with him and forces him to leave Kotaro alone, Teddy at first doesn't resist. He gradually realizes how important Kotaro was to him and risks disappearing for good to get back to him.
  • Empathic Weapon: Teddy can transform into New Den-O's weapon, the MacheTeddy.
  • Meaningful Rename:
    • Originally he was Neotaros, but after Kotaro became disillusioned with Ryotaro, he was rechristened Teddy.
    • In Episode Blue, when Teddy is briefly contracted to Owner, his name is changed to Aleksandrovic.
  • Only Sane Man: A down-to-earth kinda guy, especially when compared to the other Imagin.
  • Stealth Pun: In the anime short before Episode Blue, the Imagin are eating chicken tendon, and they wouldn't understand why Teddy is crying his eyes out just watching them.
  • Talking Weapon: His MacheTeddy form.
  • Weapon Tombstone: In Let's Go Kamen Riders, Teddie gets killed in the past trying to protect the Rider Scouts from Shocker. The scouts plant his remains, MacheTeddy, in one of their hideouts, in order for the Riders in the future to find the Time Capsule buried underneath.
  • You ALL Look Familiar: Teddy's appearance came from Kotaro's listening of the Owner's stories about his grandfather, Momotaros and the other Imagin. Thus he resembles all four Taros while maintaining his own image.
    Shiro/Kamen Rider Yuuki 

Shiro/Kamen Rider Yuuki Hijack Form

Portrayed by: Yuki Matsumura (voice), Kazutoshi Yokoyama (suit)
"You... why must you make Sora sad?"

The primary antagonist of Final Countdown, Shiro was a man from the Edo period who lost Sora, the love of his life, and was unable to move on. After dying, he discovered the Ghost Train and plotted to reverse the worlds of the living and the dead, bringing Sora back to life no matter the cost. He kidnapped Ryotaro in order to further his goals, but eventually had to personally enter battle as Yuuki Hijack Form.

  • Affably Evil: While Ryotaro is virtually his prisoner, Shiro initially treats him in a civil manner, at least until Ryotaro starts showing signs of breaking free of Shiro's control.
  • Afterlife Express: The Ghost Train, a spectral steam engine with a skull mounted on the face, somewhat reminiscent of Final Fantasy VI's Doomtrain.
  • Battle Tops: Exploding toy tops.
  • BFS: SavageGasher; it's made up of two complete DenGasher sets.
  • Finishing Move: Terminate Flash
  • Gang of Hats: Fitting in with this ability, Shiro's Imagin minions are associated with darkness (Ghost, Phantom, Shadow).
  • If You Ever Do Anything to Hurt Her...: He's so blinded by his love for Sora that he'll do whatever extreme it takes to prevent her from crying.
  • Love Makes You Evil: He's so blinded by his mission, that he fails to realize that Sora never wanted him to do it.
  • Necromancer: He can revive the destroyed Imagin to fight for his cause in the climax.
  • Palette Swap: The Yuuki suit is essentially a black Gaoh suit minus the chest "fangs", plus coattails, two unique DenKamen, a color changing rail-scarf, and Hijack Form gains a mechanical gauntlet.
  • Whip It Good: His weapon of choice is a whip, which he uses to also scatter about exploding tops.
  • Woobie, Destroyer of Worlds: He wants to do an act so terrible that it would turn the world upside-down, with the dead coming back to life and the living dying. But all he really wants is to save the woman he loves, who evidently died young.


Characters Introduced in Onigashima Battleship



Portrayed by: Ruka Sawaki

A young boy from Tokyo; after his mother's death he was forced to relocate to his grandmother's in the countryside. He prefers the busier city life instead of the dirtier country life, especially as he hates bugs.

  • The Stinger: As the credits roll, Yu shouts his full name at the bullies from earlier, revealing it as Yuto Sakurai. Furthermore, Deneb tentatively tries to ask Yuto if he remembered him from his childhood. Yuto responds by a Meaningful Echo of Yu's words from earlier.

Portrayed by: Shingo Yanagisawa
One of the leaders of the Oni, alongside his brother Kuchihiko. While his brother waits for him in the present, Mimihiko uses a rip in time to travel to points in the future with a small band of Oni and look for the Kirifuda that they plan to use to exterminate humanity.

Portrayed by: Eisuke Sasai
One of the leaders of the Oni, alongside his brother Mimihiko.

    Reiji Kurosaki/Kamen Rider G Den-O & Eve 

Reiji Kurosaki/Kamen Rider G Den-O

Portrayed by: Yuta Furukawa (Reiji), Hiroki Takahashi (Eve, voice), Norihito Itō (suit)
A member of the G-Men, Kurosaki uses the artificial Imagin Eve to protect the timestream as Kamen Rider G Den-O. He initially appears chasing Daiki Kaito/Kamen Rider DiEnd, who was attempting to cause a Time Paradox by killing his past self, but then he arrests the Taros as well, Eve claiming that their mucking about time with the DenLiner will only cause trouble. While he pursues Kaito, the DenLiner crew tries to sort out the situation and figure out what Kaito's overall goal is in the incident.
  • A.I. Is a Crapshoot: His artificial Doberman Pinscher Imagin, Eve, is a Knight Templar.
  • Ax-Crazy: Eve doesn't take Kurosaki's Heel–Face Turn very well...
  • Awesomeness by Analysis: Eve analysizes the opponent and can give G Den-O a command of where to attack next with great effect and does the same with his Perfect Weapon to counter finishers. However, this only works if he's facing one attack at once. When Eve takes over as G Den-O and goes Ax-Crazy, he begins doing this on his own.
  • Bling-Bling-BANG!: Out of his Rider form, his main weapon is an elaborate gold revolver, which Daiki attempted to steal in 2008.

Introduced in Pretty Den-O Appears

    Anna/Kamen Rider Den-O 


Portrayed by: Hinata Takao

A little girl who gets target by Shocker for a treasure she supposedly has.
  • Chekhov's Boomerang: Anna's mother gave her a lucky satchel, which is likely to be the treasure that Shocker is after - but they end up grabbing Melon-chan, the girl who befriends Anna in the Heisei era, and Melon-chan has a lucky draw ticket that will win the jackpot in the future, meaning it's most certainly the treasure they're after. It also ends up inside the lucky satchel 30 years later.
  • Kid from the Future: Melon-chan, the girl from the Heisei era, would become Anna's mother about 20 years later.
