Kamen Rider Double/Characters

Shotaro Hidari & Philip: Kamen Rider Double
Shotaro Hidari was the protege of the late great Hardboiled Detective Soukichi Narumi. Philip is a mysterious boy possessing the True Gaia Memory and gifted with all the world's knowledge inside his head. Together, They Fight Crime by Sharing a Body as Double.

Kamen Rider Double
The following tropes apply to both Shotaro and Philip as Double.

"Akiko(re Xtreme): "D-D-D-Double opened up! I can see inside Double!""
 * All Your Colors Combined: As its name implies, the Prism Memory enables this.
 * All Your Powers Combined: CycloneJoker Xtreme's Prism Bicker combines the power of the Cyclone, Heat, Luna, and Joker or Metal Memories to deliver a very potent Maximum Drive.
 * The Berserker: FangJoker was during its first two uses, due to Philip's difficulty in controlling it.
 * Bifurcated Weapon: Prism Bicker, which splits into the Prism Sword and Bicker Shield.
 * Bizarre and Improbable Ballistics: The LunaTrigger form fires bullets that do not just home in on the target, but can also travel in curves as Double wants. It might as well be firing bullet-shaped explosive bees...
 * My God...
 * Body Horror: Most of Double's Joker-Based finishers involve his body splitting in two. Vertically.


 * Broken Record:
 * Calling Your Attacks: All of Double's Memory Breaks, as their two halves must be in sync to use one. Shotaro makes up the names himself, and Philip indulges him to allow his partner some fun.
 * Somewhat averted with CycloneJoker Xtreme's Memory Breaks. At first.
 * May be justified, as speaking in unison is a good first step to mental synch.
 * Catch Phrase: Shotaro and Philip share not one, not two, but three of them:
 * "We are two detectives in one."
 * "We are two Kamen Riders in one."
 * "Now, count up your crimes!"
 * Cool Bike: Double's HardBoilder.
 * Everything's Better with Spinning: Episode 8. It's not called Heaven's Tornado for nothing.
 * Also, FangJoker's rider kick.
 * And CycloneMetal's Finishing Move.
 * Explosive Overclocking: Episode 27/28's Twin Maximum Drive. The effects of one person alone trying it makes its usage take on shades of Heroic RROD as well.
 * Finishing Move: Several:
 * Joker Forms: With the exception of FangJoker, forms using the Joker Memory involve Double's body separating.
 * CycloneJoker: Joker Extreme
 * HeatJoker: Joker Grenade
 * LunaJoker: Joker Strange
 * FangJoker: Fang Streiser
 * Metal Forms: Forms using the Metal Memory usually involve the Metal Memory being spun.
 * CycloneMetal: Metal Twister
 * HeatMetal: Metal Branding
 * LunaMetal: Metal Illusion
 * Trigger Forms: Forms using the Trigger Memory usually involve the Trigger Magnum firing multiple shots.
 * CycloneTrigger: Trigger Aerobuster
 * HeatTrigger: Trigger Explosion
 * LunaTrigger: Trigger Full Burst
 * CycloneJoker Xtreme: CycloneJoker Xtreme has a total of five finishing moves.
 * Double Xtreme: A tornado, larger than the one used by CycloneJoker, lifts Double into the sky and speeds them towards the foe.
 * Prism Break: A slash from the Prism Sword.
 * Bicker Charge Break: A slash from the Prism Sword after being charged up by the Bicker Shield using the Cyclone, Heat, Luna, and Joker Memories.
 * Bicker Finallusion: A laser blast from the Prism Bicker with the Cyclone, Heat, Luna, and Joker Memories. A variation with the Metal Memory replacing the Joker Memory creates a laser shield that protects against powerful attacks.
 * Double Prism Xtreme: A Twin Maximum Drive with the Prism Memory in the Maximum Slot; a bicycle kick.
 * CycloneJoker Gold Xtreme: Golden Xtreme
 * A couple of other Maximum Drives without names have been performed with the Memory Gadgets.
 * Stag Phone with Heat Memory: Engulfs the Stag Phone in fire.
 * Bat Shot with Luna Memory: Sets off a series of flash bulb bursts that disorient the target.
 * Fusion Dance: It's not really two people fusing into one, but more like the soul of one person goes into the other's body. So there's a limp body that needs protecting.
 * Played straight when Double's CycloneJoker Xtreme form fuses both Shotaro's and Philip's bodies together.
 * Giving Someone the Pointer Finger: Before the beatdown.
 * Incendiary Exponent: The Heat Memory can ignite HeatJoker's right fist or the Metal Shaft as HeatMetal for the Memory Break.
 * Mid-Season Upgrade: FangJoker
 * Multiform Balance
 * Jack of All Stats: The Joker forms, except FangJoker.
 * Mighty Glacier: The Metal forms.
 * Glass Cannon: The Trigger forms.
 * Lightning Bruiser: FangJoker
 * Super Mode: CycloneJokerXtreme
 * Serial Escalation: CycloneJoker Gold Xtreme
 * Power Gives You Wings: CycloneJoker Gold Xtreme from The Movie, which bears a resemblance to Blade's Jack Form.
 * Razor Wind: CycloneMetal can execute these with the Metal Shaft even without using a Memory Break.
 * Rubber Man: LunaJoker can stretch his right limbs.
 * Spotlight-Stealing Squad: The Heat Memory is probably the most used memory of all, not just within the three (four if you count fang) Philip uses.
 * In a similar vein, Shotaro prefers the Joker Memory the most.
 * Theme Music Power-Up: Every time Double transforms.
 * What Could Have Been: CycloneAccel Xtreme which is the super mode of Ryu if he replaces Shotaro in Double's formation. Only seen briefly, never used.

Shotaro Hidari/Kamen Rider Joker | Actor: Renn Kiriyama
Shotaro was the protege of the private detective Soukichi Narumi. Upon the events of Begins Night he takes up on his mentor's mantle, solving Dopant cases. His Gaia Memories, featured on the left side of Double, grant Double a weapon or a fighting style. In the second movie, he takes on the mantle of Kamen Rider Joker after Philip is kidnapped, using a Lost Driver and the Joker Memory to transform.

"Shotaro: "I'm here to screw up your plan.""
 * Arc Words: "Hard-boiled", what with him being a private detective and all. It makes its way into his bike, the Machine HardBoilder.
 * Badass Normal: Aside from having the Double Driver and training in detective work, Shotaro is more or less a normal human being when not Double.
 * Arguably carries over into his transformation as Kamen Rider Joker. Not only does he have no special powers or weapons outside of enhanced strength, supplementary materials show that stats-wise it is in every way weaker than Cyclone Joker.
 * Belligerent Sexual Tension: Arguably, with Akiko.
 * Berserk Button: Don't you dare make anyone cry in his presence.
 * In particular, the sight of someone crying has lead him to threaten Nasca to never make the children of the city cry and also to attempt when Ryu breaks down in tears after.
 * Betty and Veronica: The Betty to Ryu's Veronica for Akiko's Archie. He loses.
 * That's most certainly a Your Mileage May Vary since he didn't ever seem to be in the running.
 * Cannot Spit It Out: He can't bring himself to tell Akiko about her father's death, nor can he tell a little girl . The Movie has Akiko finding out anyway, but she still wants Shotaro to openly say it to her.
 * In the Director's Cut of the film, there's a new scene where Shotaro promises to sit down with Akiko and tell her everything about her father after they resolve the issue with the D Dopant.
 * Can't Catch Up: Shotaro gets this after.
 * Cartwright Curse: A non-lethal variation, but every single time he shows interest in a woman, she's either the Monster of the Week or simply doesn't notice.
 * Chivalrous Pervert: He's going to do nearly anything for a lady he fancies. Taken to its logical conclusion during the Invisible Dopant arc, wherein Lily Shirogane lands on Shotaro in an, er, compromising pose.
 * Dark and Troubled Past: Somewhat implied in the Jewel Dopant arc, where his flashbacks show him repeatedly running away from Jinno back when the latter was a beat cop.
 * Finishing Move: As Kamen Rider Joker, Shotaro has two, arguably homages to Kamen Rider Black:
 * Joker 1: Rider Kick
 * Joker 2: Rider Punch
 * The Heart: It's his good heart that makes Philip ultimately reaffirm their partnership, . He also manages to transform Ryu Terui from a rage-powered man who hates Futo to a warrior on the side of love.
 * The Hero
 * Heterosexual Life Partners: With Phillip, at least by the end. They even call each other 'partner'.
 * Hey, It's That Guy!: Renn Kiriyama was in a production of The Prince of Tennis musicals as Bunta Marui.
 * Homage: Kamen Rider Joker from The Movie is one to Kamen Rider Black, arguably.
 * I Do Not Like Green Eggs and Ham: Shotaro's reaction to the Jidai Geki Show Within a Show Kaze no Saheiji, Panic Revenger.
 * The Kirk
 * Large Ham: Look at his facial expressions. Look at them.
 * Meaningful Name: His surname literally means "left".
 * My Greatest Failure: Sokichi's death, which Shotaro thinks is his fault because he went against direct orders from the boss. Addressed quite directly when the dying Sokichi passing on his cool hat; Shotaro says he's not ready for it, to which Sokichi responds "Then become a man worthy of wearing it."
 * Nice Hat: A fedora.
 * Private Detective: almost the Hardboiled Detective variety.
 * Private Eye Monologue: He has a penchant for these and usually ends up saying them out loud when he shouldn't. Every arc usually ends with one.
 * Promoted Fanboy: Renn Kiriyama was a fan of Kamen Rider Black as a child.
 * Running Gag: His "Half-boiled" lifestyle, used to mock his self-proclaimed hard-boiled image.
 * Small Name, Big Ego: A mild version; he's somewhat competent, just not as hardboiled as he thinks he is.
 * Spanner in the Works: Both to plans, initially and later to Ryubee's. Ironically  would end up relying on Shotaro being this to Ryubee, calling him a Wild Card. Then, he Lampshades this against Foundation X:
 * Small Name, Big Ego: A mild version; he's somewhat competent, just not as hardboiled as he thinks he is.
 * Spanner in the Works: Both to plans, initially and later to Ryubee's. Ironically  would end up relying on Shotaro being this to Ryubee, calling him a Wild Card. Then, he Lampshades this against Foundation X:


 * Weapon of Choice: His Gaia Memories provide these for Double:
 * Bare-Fisted Monk: The Joker Memory, which allows Double to perform Rider Kicks/Rider Punches/Rider Chops. While Shotaro uses the T2 Joker Memory to transform into Kamen Rider Joker in The Movie, he uses his normal Joker Memory in episode 49.
 * Simple Staff: The Metal Memory with the Metal Shaft. Turns into a whip with the Luna Memory on the right side.
 * The Gunslinger: The Trigger Memory with the Trigger Magnum.

Philip | Actor: Masaki Suda
Philip is a mysterious boy, possessing the True Gaia Memory. He was rescued by Soukichi Narumi and Shotaro during the events of Begins Night. He aids Shotaro in solving Dopant cases by accessing the Gaia Library, allowing him to look up endless amounts of information. This ability also lends itself to his obsession with research. His Gaia Memories, on Double's right, grant him an elemental power, or in FangJoker's case, an upgrade.


 * Acting for Two: Appears in flashbacks as during Forever A to Z and . Though this may simply be.
 * Attractive Bent Gender: See Disguised in Drag below.
 * Big Eater: Philip will do this for the sake of his research.
 * Catch Phrase: "Fascinating!", as well as "Bingo!" as a minor one.
 * Cute Bookworm: Shy? Not exactly. Vulnerable? Depends. Cute and brainy? Definitely. Also doubles as Badass Bookworm.
 * Deadly Upgrade: FangJoker set Philip's mind on fire at first, despite it taking the protagonists two minutes after its television debut to get proper control over it.
 * Disguised in Drag: Except for his voice, he makes for a very convincing Wakana. Well, his clothing is marketed towards women...
 * Dude Looks Like a Lady
 * Elemental Powers: His Gaia Memories allow access to these:
 * Blow You Away: The Cyclone Memory.
 * Playing with Fire: The Heat Memory.
 * Lunacy: The Luna Memory; Word of God gives its power as "Illusions", but it seems that stretching is the primary manifestation of this power. See the main entry for more information.
 * Everything's Better with Dinosaurs: The Fang Memory, made to protect him, has a Velociraptor-like Live Mode, and allows access to the spiny FangJoker form.
 * The Exotic Detective
 * Extreme Omnivore: Philip develops a taste for... vinegar, after Akiko used it a couple of times on him as an all-purpose elixir.
 * Hair Decorations: Freakin' binder clips.
 * Heterosexual Life Partners: With Shoutaro, at least by the end. They even call each other "partner".
 * Immortality Begins At Twenty: Delusion Diary #11 hints that Philip will forever remain seventeen years old because
 * Improbable Hairstyle: Very noticeble in episode 16. His hair looks messy after taking off his motorcycle helmet, but in the next shot it's as perfect as always.
 * Instant Expert: Every now and then the data Phillip searches for will stick in his head for a while.
 * Knowledge Broker
 * The Lancer
 * Library of Babel: More like a library-shaped Search Engine of Babel, but the Gaia Library is pretty much this.
 * Meaningful Name: . His name also references Philip Marlowe.
 * Mysterious Waif
 * Of Corpse He's Alive: Whenever his mind is in Double's body, Philip is unconscious, so his lifeless body is a sitting duck. In episode 7, nobody tried to interact with them, but Akiko had to make-believe they were napping sweethearts, so as not to draw attention on the bus.
 * Scarf of Asskicking: The Cyclone Memory comes with the iconic scarf. Double's scarf is known as the Windy Stabilizer.
 * Skilled but Naive
 * The Smart Guy
 * Spell My Name with an "S": His name is spelt as "Philippe" in the aura that surrounds his body when he enters the Gaia Library, but now Toei seems to have gone with Philip.
 * Spikes of Doom: The Fang Memory.
 * The Spock
 * The Watson
 * Wiki Walk
 * The Smart Guy
 * Spell My Name with an "S": His name is spelt as "Philippe" in the aura that surrounds his body when he enters the Gaia Library, but now Toei seems to have gone with Philip.
 * Spikes of Doom: The Fang Memory.
 * The Spock
 * The Watson
 * Wiki Walk
 * The Watson
 * Wiki Walk

Akiko Narumi/Terui | Actor: Hikaru Yamamoto
Akiko is the Boss's daughter, coming in to replace her father. As Shotaro's landlady she proclaims herself as the Chief of the Narumi Detective Agency, specializing in Dopant cases.


 * Acting for Two: Plays Melissa in the Double part of Movie War Core; she even notes the resemblance.
 * Armed Legs: Played for laughs with her slipper.
 * Belligerent Sexual Tension: With Shotaro, arguably.
 * Berserk Button: Akiko will cop to the beautiful part, but she's no middle-schooler!
 * Betty and Veronica: The Archie for Shotaro's Betty and Ryu's Veronica. She chooses Ryu.
 * Big Eater: Can wolf down enormous quantities of sweets
 * Big No: After giving word of her treat to two men whose appetite she knows nothing about.
 * Catch Phrase: "No one told me about this[[!"
 * The Chick
 * Crouching Moron, Hidden Badass: She as actually quite the competent detective, when the chips are down.
 * Happily Married:
 * Iconic Item: Her slipper, of course.
 * The Idiot From Osaka: Has shades of this, given her quite black and white view of the world, but she does keep Shotaro focused on the case.
 * Kansai Regional Accent: Akiko refers to herself using the uchi- pronoun. It does help that her actress Hikaru Yamamoto is from Osaka just like her character.
 * Kawaiiko
 * Manic Pixie Dream Girl: One that Shotaro doesn't want in his life.
 * The McCoy
 * The Napoleon: Don't call her a middle-schooler (but she'll gladly be called beautiful).
 * When You Coming Home, Dad?: Her relationship with her father was like this when she was a child, with Akiko becoming upset that he was too busy to visit her, including on her birthday (though she wasn't aware at the time that he was a Kamen Rider.)
 * Official Couple: With Ryu
 * Shoe Slap: Akiko's slipper-slap acts as a Dope Slap (on Shotaro ), as a Get a Hold of Yourself, Man! (on Philip in episode 4), then finally gets played straight (used on ).
 * In Ep. 14, Shotaro gets payback by hitting her with her own slipper.
 * In a more meta example, she combines the slipper slap with Percussive Maintenance in the music video for the opening theme song. The results are bizarre, to say the least.
 * Durning her dream in the Nightmare arc, her slipper serves as CycloneJoker's primary weapon, and she beats the crap out of the Nightmare Dopant with it (or tries to, at least).
 * And she manages to outdo herself yet again in episode 40 by slapping Wakana in her Claydoll form.
 * Tsundere

Sokichi Narumi/Kamen Rider Skull (Crystal) | Actor: Koji Kikkawa
Sokichi Narumi was Shotaro's boss, who taught the young man the trade of a Private Detective. During a mission to liberate a young man he dubbed Philip, he was shot at and was killed. The events of Movie Wars 2010 reveal that he was Kamen Rider Skull, while Movie Wars CORE is a Whole-Episode Flashback showing him as Skull Crystal ten years before the Double TV series.

"Sokichi:"


 * The Cast Showoff: Koji Kikkawa sings his own theme song.
 * Cool Bike: The SkullBoilder, which is a black version of the HardBoilder.
 * Cool Old Guy: Well, not THAT old, but you get the point.
 * Death by Origin Story
 * Finishing Move: Skull Punisher
 * An unnamed Rider Kick executed with the Skull Memory in the Maximum Slot, which creates an energy skull that Soukichi kicks towards the Dopant.
 * Not to mention, the Skull summoned by Diend Complete Form in Chō Den-O Trilogy: Episode Yellow performs a Rider Kick that more closely resembles the Joker Extreme.
 * The Gunslinger: Skull Magnum
 * Man in White
 * Mentor Occupational Hazard
 * Nice Hat: A batch of which he apparently passed on to Shotaro.
 * Not So Stoic:
 * Posthumous Character
 * Super Prototype: Skull is the prototype for Double, best illustrated by its being a jack-of-all-trades combination of Shotaro's Memories (melee brawler like Joker, good defense like Metal, The Gunslinger like Trigger).

Ryu Terui/Kamen Rider Accel | Actor: Minehiro Kinomoto
Ryu Terui is a police superintendent assigned to the Futo Police Department's Paranormal Crime Investigation Division, and is thus Jinno and Makura's superior. His family was murdered by a man with a W memory, giving him a motivation to exact revenge. When he meets up with the enigmatic Shroud, she gives him his gear, allowing him to transform into Kamen Rider Accel.

""Don't question me." "Now, let's break away!" "Despair awaits you at the finish line." "It's time for your despair!""
 * Arch Enemy: Isaka
 * Badass Biker: Let's see: his attire completely fitting of a biker (leather jacket and pants, riding gloves and boots), he rides around on a motorcyle that's not a Rider Machine (and a Ducati at that ), he has a motorcycle Motif as a Rider, and he can become a bike while transformed into Accel.
 * Berserk Button: He won't listen to reason once the Weather Dopant comes calling. Learning to rein himself in whenever Weather baits him is part of his Character Development.
 * Betty and Veronica: The Veronica to Shotaro's Betty for Akiko's Archie. He wins.
 * The Big Guy
 * Body Horror: His Bike Form takes after the Final Form Rides of the previous series, with some subtle but significant differences.
 * Catch Phrase: Four of them.


 * Chick Magnet
 * Cool Bike: Ryu's rad red Ducati 999, Diablossa. He also has a Bike Form as Accel, all Conspicuous CG, but also Rule of Cool.
 * Cool Sword: The Engine Blade.
 * Death by Origin Story: One that mirrors V3's, natch.
 * Death Seeker: Ryu becomes one when he finally tracks down Dr. Isaka. Shotaro calls him out on it, and he eventually gets over it.
 * Finishing Move: Several:
 * Accel: Accel Glanzer
 * Engine: Four variations:
 * Dynamic Ace: The EngineBlade blasts a giant letter A out of the blade into the enemy.
 * A-Slasher: Accel uses the EngineBlade to make three slashes in the shape of the letter A, be it a birds eye view or in front of him, to attack.
 * Engine Bike Dasher: Accel transforms into Bike Form and then drives straight through the target.
 * (Unnamed): Accel spins around while slashing multiple targets before stopping a moment to spin into the opposite direction (still slashing) and then stops again to finish them off with normal slashes.
 * Cyclone: Accel performs a wind-powered slash with the EngineBlade.
 * AccelGunner: Gunner Full Break
 * AccelTurbuler: AccelTurbuler Phoenix
 * Trial: Machine Gun Spike
 * Trial/Engine: Machine Gun Slasher
 * AccelBooster/Engine: Boost Slasher
 * Fire, Ice, Lightning: Accel's Engine Blade has settings for steam, fire, and lightning, representing three types of engines (Steam, Jet, and Electric).
 * Happily Married
 * Homage: His character design mirrors that of Kaneda. Also, his Rider armor is red and has a monoeye, he holds a high rank despite being young, and is rivals with one who has a W crest... Char Aznable?
 * It Was a Gift: All of his gear was given to him by Shroud.
 * Juggle Fu: Part of Machine Gun Spike. He starts the Trial Memory's countdown, throws it ahead of him, runs up to his opponent and kicks them an insane amount of times, then catches the Trial Memory on its way down.
 * Kirk Summation: To Shroud in episode 45
 * Love Redeems: He believes his love for Akiko helped him overcome his craze for vengeance.
 * Multiform Balance
 * Accel: A Mighty Glacier thanks to its heavy armor and exceptional attack power.
 * Trial: A Fragile Speedster that loses much of Accel's armor in return for moving at Super Speed.
 * Booster: The Jack of All Stats thanks to its having more armor than Trial but greater speed than Accel, plus the ability to fly. Also be an Eleventh-Hour Superpower and possibly not a regular form since.
 * Name's the Same: A red warrior named Ryu whose motivation is the loss of a loved one and who gets the girl at the end? Not the first time Toei's done it.
 * Official Couple: With Akiko.
 * The Only One Allowed to Defeat You: For the Weather Dopant
 * The Rival: Subverted. Ryu was introduced in "The I Doesn't Stop" as a character whose moral stance and personality were fundamentally opposed to Shotaro's, fitting the general pattern of secondary Riders introduced in the Heisei era . A rivalry, however, never developed due to both characters being willing to talk things out and genuine Character Development on Ryu's part, making Ryu more of a genuine friend to Shotaro than The Rival. Since characters in Heisei Rider shows are usually far more willing to fight rather than talk things over, this subverts the typical role of the secondary Rider.
 * Second Rider
 * Super Mode: Accel Booster
 * Super Speed: Accel Trial
 * Tranquil Fury: How he ends up.
 * The Worf Effect: Gets hit with this around episode 45 onward.
 * Somehow justified, considering the fact that.
 * Also inverted in that when the two worked togather
 * Hit with that well before episode 45 as he's usually the guy that gets his butt kicked in order to show how powerful the Dopant of the Week is. Most blatant is the episode right after he gets Accel Trial where he runs into a Dopant that just happens to be even faster than Trial.
 * If you mean

Detective Mikio Jinno | Actor: Takeshi Nadagi
Detective Jinno is a friend of Shotaro's, frequently letting him deal with Dopant cases. He is never seen without his trademark back scratcher.


 * A Day in the Limelight: The Jewel Dopant arc.
 * Actor Allusion: At one point he notes that Takeshi would be a nice name. Also, his use of Gratuitous English mirrors his schtick as a Fake American. And the name "Catherine" pops up later...
 * Clear My Name: The subject of episodes 41-42.
 * Crouching Moron, Hidden Badass: In Kamen Rider W Returns.
 * Friend on the Force
 * Good Is Dumb: He'll fall for anything (even Look Behind You!), but Shotaro says that it's his strength; Jinno is so earnest that people want to believe he's right, and when he believes that rough characters are actually good deep down, they want to be good to prove him correct. A prime example of this is Shotaro himself, as shown in flashbacks in the Jewel Dopant arc.
 * Gratuitous English: Most common user among the cast.
 * Hey, It's That Guy!: He's half of the duo "Dylan and Catherine", who performed the Keroro Gunsou theme song.
 * Iconic Item: His back scratcher.
 * Inspector Lestrade
 * Spanner in the Works: Doesn't even need to be in the action to fill this role in the Jewel Dopant arc.
 * Those Two Guys: With Makura.

Detective Shun Makura | Actor: Shingo Nakagawa
Makura is Detective Jinno's rookie partner, who usually quarrels with Shotaro.


 * Butt Monkey
 * Cowboy Cop: Or at least he likes to think he is.
 * Incoming Ham: "Maakurrra des'!"; for whenever he follows Jinno (or Ryuu) in introducing himself around the crime scenes.
 * Large Ham: If he's on the screen, he's overacting.
 * Sitcom Arch Nemesis: With Shotaro, though definitely not a serious case.
 * Small Name, Big Ego: In spades.
 * Those Two Guys: With Jinno.

Ryubee Sonozaki/Terror Dopant | Actor: Minori Terada

 * Nevermind how it's pronounced...
 * Palette Swap:
 * Pyrrhic Victory:

 * Morally-Ambiguous Doctorate
 * Name's the Same: He shares a name with the Peacock Undead from Kamen Rider Blade. He also incidentally develops a rivalry with the red Second Rider, much like his predecessor.

 * Defictionalization: Queen and Elizabeth are played by two members of idol group AKB48, and when they released their joint single "Love♡Wars", the Liar Dopant arc had them appear on an American Idol-esque contest (Fuuuuuutic Idol) performing the song in order to win a major label release.

 * Anti-Hero/Anti-Villain: She can be considered either one.
 * Badass Longcoat
 * Bandaged Face:
 * The Brute
 * The Chessmaster: Her opponent is Ryubee Sonozaki. Fitting the show's hardboiled theme, a billiards metaphor is used instead of chess.

Dopants
A Dopant is created when a Gaia Memory is inserted into a human body, transforming the user and granting them supernatural powers. Each Gaia Memory contains the culminated knowledge of a single topic extracted from the True Gaia Memory; thus, Gaia Memories can be based on anything from the history of Earth, from natural phenomena to abstract concepts.

In normal cases, a human requires surgery before they can use a Gaia Memory. A Living Connector is imprinted upon the skin of the user, through which the Gaia Memory can be directly inserted into the body. While this maximises the power of the created Dopant, it carries a significant risk that the Gaia Memory will consume the sanity of the user and create a strong addiction to its power.

Gaia Drivers are external mounts that can be used to insert a Gaia Memory without surgery. While this limits the power of the Memory, it removes the negative side-effects. High-ranking members of the Museum use first-generation Gaia Drivers to transform into Dopants.

Tropes embodied by the Dopants include:


 * An Ice Person: IceAge
 * Attack Reflector: Jewel can do it with energy attacks.
 * Battle Couple:
 * were a couple who became Dopants together in order to take revenge on their former employer, but then.
 * Biological Mashup: Gene, for his powers to work, he needs biological material, but can create anything from said material. For example, he created a plush cow on Shotaro's right hand with two leaves during their first fight.
 * Card-Carrying Villain: Quite a few Dopant abusers come complete with titles like Mr Question and the Radio Clown, sometimes with a one-shot Catch Phrase or Bond One-Liner.
 * Compelling Voice: Liar, who as the name implies, can literally make anyone believe anything, so long as it's not the absolute truth.
 * Dangerously Genre Savvy: Cockroach, who instead of fighting fairly, uses its Super Speed to steal W's Gaia Memories from his belt and runs away with them!
 * Disproportionate Retribution: Quite a few Dopants use their powers for really petty reasons.
 * Does This Remind You of Anything?: Gaia Memory use is paralleled with drug use.
 * Elemental Powers: Magma, IceAge, and Energy
 * Expy: Arguably, Old to Terror, given their "ancient" design and their use of a sort of sludge to attack.
 * Also, IceAge and Triceratops are the first two Dopants Accel faces, compared to Magma and T-Rex, the first two onscreen Dopants Double takes on.
 * The Masquerade Dopants could be seen as Expies of the classic Shocker Soldiers, given their skeletal design and status as easily-defeated Mooks.
 * The Gunslinger: Arms
 * Hey, It's That Guy! with a bit of Actor Allusion: Quite a few of the Dopants were in Super Sentai series:
 * T-Rex is.
 * Cockroach is a member of the Rahmens comedy troupe.
 * Arms is Abared - with a red color and him rampaging ...
 * Triceratops is
 * Invisible is Hurricane Blue.
 * Yesterday is.
 * Gene is Long from Gekiranger.
 * I Have Many Names: Some Dopants have aliases besides their Dopant names. Cockroach imagines himself as a superhero named "Roachstar", Violence prefers to go by "Mr. Question", and Liar is known as the "Airwave Clown".
 * Old is also known as "The Ager".
 * Invisibility: Invisible, though notably, Lily Shirogane didn't actually become a monster of any sort; Dr Isaka modified the Invisible Memory to allow her to use its power without such a change.
 * It's Personal: Many of the Dopants. Notable are, who attacks the literary critics that panned the book he wrote in his daughter's memory; , who wanted revenge on their old employer for firing them; and , who turns out to be and wants to get back at Saeko for.
 * Knight Templar: from the series proper.
 * Legacy Character: The final episode of the series establishes that multiples of the same Memories do exist; in this case, Anomalocaris and Cockroach.
 * Love Makes You Crazy: Oh so much. killed her lover  because he went crazy,  wishes to avenge her lover,  is Wakana's Stalker with a Crush,  is jealous to the point of putting his supposed rivals to sleep,  set his unrequited crush up as the culprit.
 * The award probably still goes to the Dopant from the Kamen Rider Skull prequel in the "Movie Core War". Unable to live with unrequited love and having a well-hidden, but highly homicidal sense of jealousy, he gained the power to turn people into bombs, set off when a carrier touches someone they love, in a rather horrendous expression of If I Can't Have You. He ends up detonating a good part of the city in a single go, just to prove the lengths he's willing to go to make everyone as miserable as him.
 * Made of Diamond: Jewel, quite literally.
 * Magma Man: Magma, who else?
 * Money Fetish: The Money Dopant.
 * Mono-Gender Monsters: Averted; people become Dopants regardless of gender. An even funnier detail to this aversion is that some of the more 'manly' Gaiamemories, like do in fact have female users.
 * Mook Maker: The Commander Dopant can create Faceless Goons called Masked Soldiers out of thin air.
 * Mythology Gag: Hopper is based on a grasshopper and fights with powerful kicks. Sound familiar?
 * While we're on nods to Kabuto, how about Cockroach (another insect) having Super Speed as its main power?
 * One-Winged Angel: Certain Memories (particularly the ones based on animals) can make their user a larger Dopant, done in Conspicuous CG.
 * Quetzalcoatlus is this right of the bat, with no intermediate humanoid form ever seen (though this might be partly because the "user" was a parrot).
 * does this as a result of it's Gaia Memory evolving.
 * Overnight Age-Up: Old's specialty, at a price of about 10,000 yen for every year he ages the victim up. (Payment up front.)
 * People Puppets: Puppeteer, though he mostly sticks with his dead daughter's Creepy Doll.
 * Psycho for Hire: Cockroach and Old.
 * Right Hand of Doom: Violence, whose left hand is an Epic Flail.
 * Roaring Rampage of Revenge: Several are motivated solely by revenge.
 * Shock and Awe: in the finale.
 * Stock Dinosaurs: T-Rex and Triceratops.
 * Stringy-Haired Ghost Girl: Virus can come very close, even though she's still alive (though in a coma).
 * Super Speed: Cockroach, Smilodon, and Donburi.
 * Sweet Tooth: Sweets, who sneaks desserts while working as a maid for the Sonozaki family.
 * Teleport Spam: Zone
 * Two Guys and a Girl: . Him finding out that his two friends loved each other didn't go... well with him.
 * Which was very similar to Isamu Bitou and (he had no problems with them getting together, but still got screwed over for it).
 * Voluntary Shapeshifting: Other than anyone with a Memory, Dummy can take on the appearance of anyone he wants, usually the dead to take advantage of the dead person's loved ones.
 * Well-Intentioned Extremist: Triceratops.
 * It seems to be this way with the original Cockroach, as he believed he was being a superhero.
 * With Great Power Comes Great Insanity: Memories used without a Driver madden their user,.
 * Using a Memory without the bio-port will cause grievous bodily harm and even death with extended use, as seen with the underage high school students who shared the Bird Memory.
 * Yandere (disambiguation): Several of the Dopants are this trope, including the T-Rex Dopant, the Violence Dopant, and the Spider Dopant.

 * Card-Carrying Villain: not afraid of proclaiming himself to be evil.
 * Catch Phrase: "Now, look forward to Hell."
 * Dawson Casting: Mitsuru Matsuoka was 40 when he played Katsumi, who appears to be in his early to mid-20s based off the information given. Possibly justified since storywise he was
 * Early-Bird Cameo: A rather surprising one: SOPHIA was a guest at Anime Expo 2010 in Los Angeles, and during their last song, Eternal came on stage.
 * Fallen Hero: As portrayed in W Returns: Kamen Rider Eternal,
 * Hey, It's That Guy!: Fans of the band SOPHIA (which performs the theme for the movie) may recognize him as the vocalist.

 * Other fans say Eternal looks a little bit like a color-swapped G3 Mild, with a cape and no huge arsenal of firearms.
 * : Sure, Katsumi is a ruthless fighter and killer, but

 * Palette Swap: Eternal Red Flare from W Returns: Eternal, which is revealed to be the result of using the experimental T1 Eternal Memory. Its resonance with Daido causes it to evolve into Blue Flare before burning out entirely.

All Movie Dopants

 * :  Subverted by a little that
 * Evil Counterpart: To Double's own Gaia Memories.
 * Fallen Hero: The group began acting as mercenaries, still holding onto their ideals. One of the effects from the serum that kept them active was the gradual vanishing of their emotions: by the time of A to Z, most -if not all- of them had already fallen to this, even if most of their personality traits were retained.
 * Phlebotinum Rebel: Villainous version.
 * Super Soldier
 * We Have Reserves: when, he dismisses her and tells her that he can just make more of them.
