Kit Taylor/Kamen Rider Dragon Knight II / Kamen Rider Onyx I
Portrayed by: Stephen Lunsford, Voiced by: Tatsuhisa Suzuki (Japanese dub)
In the year since Kit's dad mysteriously vanished, Kit has gained a reputation as a criminal (which he claims is completely undeserved). He appears to have stumbled into the Rider war completely by accident. While he genuinely wants to help out, one of his first priorities is trying to find and help his dad. His dad's disappearance were set up by Xaviax. After Kit rejected Xaviax's manipulation and joined forces with Len, Xaviax eventually succeeded in sending Kit to the Advent Void. Xaviax took the Dragon Deck as a prize, but Kit got a replacement deck from Eubulon after being pulled back into the real world and became Kamen Rider Onyx.
- Adaptational Heroism: In Kamen Rider Ryuki, Onyx's counterpart Ryuga was the Big Bad of The Movie. In Dragon Knight, Onyx is only evil in Kit's dreams. When Kit finally becomes him, he's still a hero.
- Adaptational Personality Change: Somewhat. While Kit is still the one of the main heroes of the story, he can be pushed to use the Final Vent to vent another Rider (in this case, Albert/Spear). This is different from Shinji, who is dead set in his plan to stop the Rider War and thus barring Ryuga, never killed another Rider as a result.
- Bond Creature: Dragreder the dragon (Dragranzer in Survive Mode) as Dragon Knight, Dragblacker the dragon as Onyx.
- Cool Bike: His Suzuki Katana 600, which transforms into his Dragon Cycle, the Adventcycle (a generic motorcycle for all the riders), and Dragredder transforms into one.
- Dark Is Not Evil: As Onyx. He is not a naive hero anymore, but that is because of what he had to go through, not the Onyx deck.
- Deadpan Snarker: Makes sarcastic remarks every now and then. His reaction when he is told that the other riders will be after him because he sides with Len is pure sarcasm.Kit: Great. Now, because of you I have a big Kick Me sign on my back.
- Disappeared Dad: Kit's main motive at first is to find out what happened to his dad. He later discovers his father was rendered into a vegetative state due to Xaviax's schemes, something the alien general and Strike are fond of using to manipulate him with.
- Evil Costume Switch: Subverted with a vengeance. After a series of nightmares lead him to believe that Onyx is some kind of dark force threatening to possess him, Kit takes up the mantle of Onyx while Adam uses the Dragon Knight armor until the end of the series. Oddly enough, Chance and Price state that all the Riders have those nightmares because it's actually the ADVENT BEAST trying to take over the Rider it's bonded with!!
- Explain, Explain... Oh, Crap!: Kit explains to Torque and Camo why they should not fight each other.Kit: Torque, stop, listen. Xaxiax has been tricking the other riders, offering each one something they want. He told Incisor he'd give him a million bucks to take out Wing Knight. This guy (points to Camo) wanted a challenge. Xaviax told him Wing Knight was the toughest man on two worlds. Everyone who's after Wing Knight... (realizing he has been tricked) is working for Xaviax...Torque: [laughs] Congratulations, Kit. Thank you for playing. Let's tell him what he's won... a one-way pass to the Advent Void.
- Foster Kid: Part of his backstory is that he spent a year in the foster care system since his dad disappeared. He briefly interacts with his foster family when he leaves their care in the premiere, but is otherwise preoccupied with his biological dad throughout the series.
- Frame-Up: It turns out his criminal record was not his fault.
- The Hero: Obviously, being the first rider.
- Instant Awesome: Just Add Dragons!: Dragon themed rider with finisher called Dragon rider kick.
- Kill It with Fire: His Advent Beast's main mode of attack.
- Luckily, My Shield Will Protect Me: Guard Vent.
- Major Injury Underreaction: When vented. Some riders pleaded for mercy, some were defiant. Kit claimed that he feels weird and assured Len that everything is okay before diasappering.
- My God, What Have I Done?:
- After he realized that Torque tricked him and he nearly got both Len and himself vented.
- His reaction after venting Spear.
- Naïve Newcomer: But he does get legitimately more badass as time goes on.
- Open Mouth, Insert Foot: Quotes this trope word to word after unknowingly hurting Chris.
- Our Hero Is Dead: Gets vented in episode 31. But the next episode is the one where his friends find the guy who can get people out of the Advent Void.
- Properly Paranoid: In 2World 1Hearts. When Colonel Stuart introduces himself as representative of a governmental weapons department, Kit immediately jumps to the conclusion that he wants to apply rider technology to the weapons industry.
- Red Is Heroic: As a main rider in red armor, this is given.
- Roaring Rampage of Revenge: "This is for Chris..."
- Spared by the Adaptation: Because Onyx's deck is the hidden 13th Deck and Onyx didn't participate in the initial Rider War, Onyx thus survived unlike Ryuga who is killed at the end of Episode Final.
- Superpowered Evil Side:
- Kit believes Onyx to be this at first. Subverted when the Onyx deck turns out to just be an unfinished prototype deck that's no more evil than his familiar Dragon Knight deck.
- Played partially straight when it's revealed by Chance and Price that Onyx is originally a manifestation of Dragreder trying to take control of Kit in his dreams!
- Superior Successor: The only advantage the Dragon Knight deck has over the Onyx deck is a survive card; other than that, Onyx is superior to Dragon Knight.
Len/Kamen Rider Wing Knight
Portrayed by: Matt Mullins, Voiced by: Satoshi Matsuda (Japanese dub)
Last of the Ventaran Kamen Riders and Xaviax's number one target. Tries to keep everyone out of the Rider conflict for fear of someone getting hurt, but accepts Kit's help once he's gotten involved following some complications.
- Adaptational Heroism: While both Ren and Len starts off as an Anti-Hero, Len drops his Anti-Hero mannerism sooner than Ren. Len is also friendlier and befriends more people than Ren ever did, even if some of his friends were Fire-Forged Friends.
- A Friend in Need: Kit took him in as he was wounded fighting Torque and practically homeless on Earth.
- Badass Cape: His Advent Beast can attach to him in rider suit to form this.
- Badass Biker: Naturally.
- Bat Out of Hell: The overall malice depends on your allegiance.
- Big Brother Instinct:
- To Adam before his betrayal.
- Starts feeling this way for Kit through the early part of the story.
- Break the Badass: Comes close to this when Chris sacrifices himself to save him. Losing Kase and Kit pushes him over Despair Event Horizon.
- Bond Creature: Black Wing the bat, Advent Beast of the Wing Knight deck. Its form in Survive Mode is called Black Raider.
- Cool Bike: He has 4: his Kawasaki ZX-14 (which transforms into his Wing Cycle), his Adventcycle, and Black Wing turns into one for his survive mode Final Vent.
- Cool Sword: His rapier, which doubles as his card-slot. Also his Sword Vent.
- The Chains of Commanding: Len mentions he wasn't that high on the chain of command with the original Ventaran Riders, now he finds himself leading the resistance against Xaviax on Earth.
- Dark Is Not Evil: A bat themed rider, who mostly wears black and yet he is one of the heroes. It also depends on your allegience. He is fairly amiable to people he trusts and fairly strict or even downright terrifying to people he does not.
- Deadpan Snarker: Some of his reactions cross into this.Len: [to Kit, very much angry] You are Kamen Rider Dragon Knight now. Happy?
- Despair Event Horizon: After a string of events causes him to be the only rider standing - again - and with Xaviax's plans only delayed and in possesion of the Dragon Knight deck. He is left as Empty Shell until Michelle delivers a Hope Spot.
- Expy: Admit it, when you saw this guy, you thought "Hey, it's Batman in a knight costume!". Or for those aware, "Hey, it's Knight, the British Batman!" (yes, that's actual DC Comics canon).
- Fire-Forged Friends: Has a tendency to create this kind of bond with people he trusts. Kit and Adam being a notable example.
- Friendship Moment: Mentioned above. Len got severely hurt surving Torque's Final Vent and couldn't go to hospital for obvious reason and without any place of his own, Kit and Maya brought him to Kit's flat. It was shortly after Kit realized that Torque tricked him into believing that Len was working for Xaviax and nearly got both of them vented.
- Heartbroken Badass: Following Kase being vented. He expresses this by Roaring Rampage of Revenge against Strike.
- It's Personal: When Kase was vented by Strike.
- I Did What I Had to Do: How he feels about having to vent the Earth Riders to get the Advent Decks back.
- Intergenerational Friendship: His friendship with basically anyone outside the Ventaran riders. Len looks 20-something, but he is actually in his 80s due to spending decades in suspended animation.
- Last of His Kind: Originally thought to be one until Kase and later Master Eubulon is introduced to the story.
- Limited Wardrobe: Wears nearly the same outfit all the time. Justified as he is homeless on Earth.
- The Men in Black: Literally so. He is never seen wearing anything else but black.
- Roaring Rampage of Revenge: Once Kase is vented, Len cuts the crap and goes right for the throat. Strike is practically crapping his pants in fear at that point.
- Sole Survivor: At first he thinks he's this, since there's no other known Ventaran Riders that made it out alive from Xaviax's invasion of Ventara. Kase's appearance and later Eubulon's would subvert this.
- Played straight again at the end of the Rider War arc, as he's the last Rider standing after Kase, Kit, and all the Earth Riders were vented.
- Sugar-and-Ice Personality: As many a second rider, he comes across as aloof to strangers, but cares about those close to him greatly.
- Supporting Leader: As the more experienced fighter, who actually knows what's going on.
- Sympathy for the Devil: Despite his grudge against Adam, he cant help but wonder if his betrayal was due the fact that being stuck as a Kamen Rider meant his Advent Deck would always alert him to monster attacks making him unable to ignore them. He even says that while Adam was a good fighter, he wasnt ready to make it his life.
- Tranquil Fury: In #7. He kept an emotionless expression, but the stunning barehanded beatdown handed to two mirror monsters betrayed the feelings going on inside.
- You Are Not Alone: When he and Kit finally start working together. Also, when he becomes the last Rider standing again Maya gives him a hug.
Richie Preston/Kamen Rider Incisor
Portrayed by: Tony Moras, Voiced by: Hiroki Takahashi (Japanese dub)
A wealthy preppie cut off from his family fortune and told to get a job, he's offered a million-dollar paycheck for each defeated Rider.
- Adaptational Heroism: While still a villain, Incisor is mostly in for the money, had no idea about what's going on as he's more-or-less manipulated by Xaviax to join the War, and turns into a better person in the novel; unlike Scissors who is a Corrupt Cop and utter Jerkass that uses his Rider powers as a way to dispose of anyone who gets in his way.
- Bond Creature: Volcancer the crab, Advent Beast of the Incisor deck.
- Bounty Hunter: He's promised a million bucks for each Rider he vanquishes.
- Break the Haughty: The novel reveals he was kicked out of his house after being disowned and barely managed to land a minimum wage job at a parking lot. On the other hand, it made him a better person in such a way that Kit has hard time believing it's him upon their meeting.
- Character Development: He has become a much nicer and humbler person in the year after the main story. He genuinely cares about his friends and willingly returns to fight as a Kamen Rider so he could protect them from mirror monsters.
- Catch Phrase: "This is so uncool!". Also his last words.
- Fair Weather Friends: They were only interested in money, so they all left once his father disowned him.
- Giant Enemy Crab: His Advent Beast, Volcancer.
- HeelFace Turn: In the novel, he turns into a much better person, as he now genuinely cares about his friends and only returns as Incisor so that he could protect them from the now-feral mirror monsters. Even Kit is in disbelief of his personality change when he met Richie again.
- Jerkass: Spoiled rich kid prone to womanizing and whining. That's not even starting with him being completely willing to assault someone just for a paycheck. Not knowing that riders can be vented doesn't help his image very much.
- I Just Want to Have Friends: The novel reveals that he knew his friends are only about money, but got involved with them anyway because he didn't want to be alone. They all left him after he was disowned.
- Locked Out of the Loop: He doesn't know anything about what's going on, Xaviax's plans or being vented. That is ultimately his fate.
- Meaningful Name: Richie the rich kid.
- Only in It for the Money: Becoming rich again is his only reason for being a Kamen Rider.
- Refusal of the Call: He refuses to become Incisor again in the novel. He goes back on his word later and joins the No Men so he could protect his friends and do the right thing.
- Small Role, Big Impact: Like Scissors, while he only appeared in a few episodes, seeing him get vented showed Kit how dangerous being a Kamen Rider is.
- Spoiled Brat: Why his father disowned him.
- Starter Villain: First of the villainous riders to appear.
- Punch-Clock Villain: He doesn't know about Xaviax's master plan or the motives of the opposing Kamen Riders, all he wants in the end is his paycheck.
- Upper-Class Twit: He used to be one before his father disowned him.
- We Hardly Knew Ye: The first rider to be vented.
Drew Lansing/Kamen Rider Torque
Portrayed by: Christopher Foley, Voiced by: Koji Yusa (Japanese dub)
A scam artist and one of the few on Xaviax's side to be aware of his true plans, recruited to "convince a group of men to wage an all-out war". Tries to turn the various Riders against each other for his own benefit, with... mixed results.
- Adaptational Villainy: Zolda, while not the most heroic of riders, was ultimately an Anti-Hero. Torque, on the other hand...
- Alpha Strike: His Final Vent.
- Awesome, but Impractical: His Final Vent qualifies as More Dakka, but takes time to load during which he has to stand still. It plays a role in him getting vented.
- BFG: His deck is loaded with these!
- Bitch in Oxs Clothing: Initially appears as Kitss true friend while presenting Wing Knight as Xaviaxs dragon. Then Kit realises that all the Riders Xaviax recruits are after Wing Knight.
- Bond Creature: Magnugiga the ox, Advent Beast of the Torque deck.
- Boxed Crook: 2World 1Hearts has him pulled out of prison on something like probation because No Men can't be choosy over who they recruit to deal with the crisis.
- The Chessmaster: He tries to be, but things don't always work out the way he would want them.
- Con Man: Referred to as this by Strike, and later Maya, after he is vented. His origin flashbacks revealed that prior to the series, he made a living trying to sell fake multi-purpose cellphones. That is, until the cops showed up at his door, leading to his recruitment by Xaviax.
- Demoted to Extra: Torque is vented/killed much earlier than Zolda, as Torque is among the first 4 to be vented while Zolda is among the final 4 survivors of the Rider War and could be considered the Tritagonist of Ryuki.
- A Load of Bull: His main theme.
- More Dakka: Expectable from BFG using rider. His Final Vent turns Magnugiga into one load of cannons that all shoot at the same time. Ryuki named it End Of The World.
- Oh, Crap!: When he hears that Maya knows he lied, he has a tiny one he quickly covers from.
- Power Fist: His Strike Vent. It's not used by either him or Zolda, though.
- Reality Ensues: Unsuprisingly, Kit refuses to believe him again without a single second thought after what he pulled earlier.
- Small Name, Big Ego: Overestimates his abilities, to say the least.
- Smug Snake: He is very sure of himself and his abilities to manipulate people. It came back to bite him in the rear later on.
- The Starscream: Unfortunately for him, Xaviax seems to have learned from Megatron's mistakes...
- Villainous Breakdown: Related to his ultimate fate as rider mentioned above. He was smug about most things up until Strike started to hunt him. He fought for survival, but got more and more desperate through the fight until he actually started to plead for mercy.
- You Have Outlived Your Usefulness: He decided to trick Xaviax. Not humored, the warlord decided to get rid of him.
Grant Stanley/Kamen Rider Camo
Portrayed by: Christopher Babers, Voiced by: Kenji Matsuda (Japanese dub)
Believes he was hired by a Private Military Contractor, and fights for the opportunity to become "the best fighter on two worlds". While specifically sent after Wing Knight, he messes up both Xaviax's and Drew's plans by picking fights with the other Riders as well, not wanting them to steal his glory.
- Adaptational Heroism: As noted below, Verde was the Big Bad of 13 Riders movie. Camo, on the other hand, has a role more equivalent to Zolda - Torque's Japanese counterpart.
- Blood Knight: He does not have any qualms about cheating to win and loves fighting. Being recruited under the pretense of fighting to be the champion of two worlds sure fits him. This is further emphasized in 2World 1Hearts where he becomes Camo again because fighting in MMA matches doesn't satisfy him.
- Bond Creature: Biogreeza the chameleon, Advent Beast of the Camo deck. Unlike his Ryuki counterpart, Verde, he did not use it. Presumably, this is due to the fact that it's main appearance had Verde kill Raia, whose counterpart on this show didn't even show up until after Grant was vented.
- Combat Pragmatist: He's not above fighting dirty if it means winning.
- Deceptive Disciple: To his fighting master, whom he studied under only so he could become the man who beat the master.
- Demoted to Extra: The Ryuki version of Camo was the Big Bad of 13 Riders movie and killed Kamen Rider Raia and Kamen Rider Knight. Here he gets vented the next episode after being introduced.
- Glory Seeker: His sole reason for becoming a rider.
- Hidden Depths: It's hinted that he is not as bad as he looks like, but that's all.
- Hypocrite: Accuses Drew of cheating during their fight when he is actually a cheater himself.
- Power Copying: While he has a Copy Vent card (like Verde) in his deck, he never used it.
- Scary Black Man: As a Combat Pragmatist and Blood Knight.
- Small Role, Big Impact: Like Incisor he doesn't last long, but his sudden appearance messes up Drew's plan for tricking Kit into joining Xaviax. His defeat also shows Brad what he has gotten into in a similar way to how Richie's defeat was for Kit.
- We Hardly Knew Ye: He is vented the next episode after his introduction. He doesn't get much further in the novel either.
James "JTC" Trademore/Kamen Rider Strike
Portrayed by: Scott Bailey, Voiced by: Tomokazu Sugita (Japanese dub)
A wanted hacker well-known in paranormal blog circles as "JTC". Xaviax broke him out of jail, and he uses his new mirror-warping ability to get at any classified secret he wants. He uses his reputation to feed information to Maya and "help" along her own Kamen Rider investigation (and thereby manipulate Kit). As a Rider, he's Xaviax's right-hand man.
- Adaptational Heroism: Downplayed — he's still a villain and keeps the role of The Dreaded, but nowhere near as vile as Ouja was.
- Adaptational Villainy: Strike works directly with the Big Bad instead of being an Unwitting Pawn for the Big Bad to do the killings. In addition, kill count wise, he vented/killed one more Rider than Asakura, giving him a kill count of fivenote compared to Asakura's fournote .
- Bond Creature: Venosnaker the cobra, Advent Beast of the Strike deck. It merged with Metalgelas and Evildiver into Cerebeast the chimera after he used the Unite Vent.
- Character Tic: JTC keeps Asakura's neck crack, adding a sickening cracking noise to it. The Japanese dub also gave it a more noticeable noise.
- Conspiracy Theorist: Was one until Xaviax proved him right.
- Deadpan Snarker: He is actually pretty funny with some of his snarks despite the fact that he usually uses them to mock his opponents' futile attempts to fight him.
- The Dragon: To Xaviax's Big Bad.
- Evil Virtues: He is the only Kamen Rider completely loyal to Xaviax. It's literally his only good feature.
- Fallen Hero: In Maya and Trent's eyes. It may depend on interpretation. He certainly doesn't agree on that.
- Fusion Dance: His Unite Vent.
- Hero Killer: While Torque was undoubtedly an Asshole Victim and Axe was more of an Alas, Poor Villain at best, Sting and Siren, two of the most unambiguously heroic Riders, are sent to the Void by his hands. Thrust, interestingly enough, was disposed of so he wouldn't become one, making Strike effectively a Pre-Hero Killer.
- Hidden Depths: Related to his Pet the Dog moment below. He may have been better at some point of time until events jaded him to the point he didn't care about anything but his own survival.
- I Fight for the Strongest Side: Joined Xaviax because he believed Xaviax's forces had the best chance of winning the war. In the video game, his story mode has him perform a HeelFace Turn because he comes to believe the Riders side is stronger (though the story mode still pits him against the good guys).
- Ironic Echo: He repeats Xaviax's comment about the Cho Brothers when he sends them after Wing Knight.James: Enthusiastic, but not very bright.
- Irony: Remember how in Ryuki, Asakura in the end fails to kill the Riders that he deliberately wanted to kill (Kitaoka, Tojo, and Shinji)? Well in Dragon Knight, JTC is the one who vented Kitaoka and Tojo's counterpart Drew and Danny respectively.
- He ends up venting Siren, whose Ryuki counterpart, Femme, killed his Ryuki Counterpart, Ouja, in the Episode FINAL movie.
- Kick the Dog: He mocks Chris' determination to be a hero and his attempts to fight him are definitely in this territory because Chris is a depressed woobie.
- Kick the Son of a Bitch: He mocks Drew's futile attempts to escape after betraying Xaviax. Unlike him demoralizing Chris, this comes across somewhat less cruel because Drew is an Asshole Victim.
- Pet the Dog: He tries to talk Danny out of venting Kit, because that would mean messing up Xaviax's plan. Then he would have to vent Danny. Why JTC did this when he had never shown a moment of remorse or hesitation over having to vent anyone is unclear.
- 2World 1Hearts reveals that he was honest about both having a brother and losing him, so he may have pitied Danny.
- The Quisling: He truly believes resistance against Xaviax's invasion is a lost cause and sided with him out of self-preservation. Maya angrily tells Trent that since he's proven himself to be one of the strongest Riders, he could have easily turned the tides in the heroes' favor.
- Smug Snake: Very appropriate due to his Advent Beast being a cobra and himself being very arrogant towards almost everybody.
- Villainous Friendship: With Xaviax, he's the most loyal to him and was somewhat worried about him when he was about to possess Kamen Rider Wrath's body.
- Villains Want Mercy: When Wing Knight goes on a Roaring Rampage of Revenge in Survive Mode on him after he vents Siren, Strike resorts to begging for mercy due to how completely Wing Knight is curbstomping him.
Brad Barrett/Kamen Rider Thrust
Portrayed by: Keith Stone, Voiced by: Shouma Yamamoto (Japanese dub)
A motocross pro that Xaviax had framed and blacklisted for sabotaging another competitor; he is convinced that he must win in "Battle Club" in order to get the proof that will clear him. He's soon set straight, but that changes nothing - Xaviax is still blackmailing him.
- Adaptational Heroism: Thrust is portrayed with a lot more sympathy than his Ryuki counterpart, Gai. In addition, Brad reveals his true colors as a good guy beneath the manipulation after seeing Grant getting vented, while Jun is still among one of the biggest Hate Sink in the entire Kamen Rider franchise.
- Arrogant Kung-Fu Guy: He is ill tempered, brash, but ultimately not as bad as other Earth riders.
- Badass Biker: He used to be succesful pro racer.
- Badass Boast: "Brad Barrett always wins!"
- The Big Guy: As Thrust, he has plenty of raw power to mow down monsters without any problems.
- Bond Creature: Metalgelas the rhino, Advent Beast of the Thrust deck.
- Clear My Name: His ultimate goal.
- Fight Clubbing: What he thinks he's doing at first. Grant's defeat at Drew's hands snaps him out of this.
- Madness Mantra: "Brad Barrett always wins!" becomes this in the Japanese dub. It's also the last words he spoke in both dubs before vanishing away after Strike vented him.
- Refusal of the Call: He initially refuses to go back to fighting. His determination doesn't last very long in this case.
- Power Fist: His Strike Vent, a rhino head with prolonged horn equipped to his right hand.
- Rhino Rampage: He is contracted to Metalgelas the rhino.
- Sixth Ranger: Subverted. Kit, Len, and Chris all know Brad isn't a bad guy and try desperately to sway him to their cause, but Xaviax orders Strike to terminate him because he feared it was only a matter of time before he defected.
Chris Ramirez/Kamen Rider Sting
Portrayed by: Michael Cardelle, Voiced by: Hiroshi Kamiya (Japanese dub)
He was raised to be fifth-generation US Marine until getting a medical discharge for advanced asthma. Still desiring to serve his country, he was recruited by a federal agent to help fight the alien invaders — unaware that he was actually fighting for the aliens. The Knights are able to correct him as to who the bad guys are, but unfortunately, asthma and Toku superheroics don't mix...
- Bond Creature: Evildiver the stingray, Advent Beast of the Sting deck.
- Flying Seafood Special: His Advent Beast, a stingray.
- The Heart: The only one of Xaviax's riders who is simply a good person and defects as soon as he knows what's going on. Strike mocks him for it.I've got to hand it to you, brother. You do have heart, just no lungs.
- Heroic Sacrifice: How he was vented. Kit and Len's reaction is justifiedly heartbroken.
- Incurable Cough of Death: A result of his asthma.
- In-Series Nickname: "The Hero Of Gramercy Heights."
- The Load: Chris believes himself to be this because his asthma holds him back. Len and Maya try to convince him otherwise. They are more successful than Kit.
- Military Brat: His ancestors were all Marines so he is logically raised to be one too. Not being able to continue family tradition reasonably causes him great angst.
- Power Copying: His Copy Vent.
- Real Men Wear Pink: Technically, it's magenta. He is not Decade or Ex-Aid.
- Refusal of the Call: In the novel. He is reluctant to let go of his dream and return as Kamen Rider Sting. He changes his mind after some talking to.
- Semper Fi: He breathes this. Also his last words.
- Sixth Ranger: Briefly. He sees himself as this and The Load.
- "Well Done, Son!" Guy: He wants to make his father proud and carry on family's military tradition, but his asthma kept that from happening.
- Whip It Good: His Swing Vent.
Danny and Albert Cho/Kamen Rider Axe and Spear
Portrayed by: Mike Moh & Tony Sano, Voiced by: Takahiro Sakurai & Ryota Murai (Japanese dub)
Two-bit crooks looking for a big score. Xaviax posed as a crime boss to recruit them for "the biggest heist in the history of Earth". After Albert gets vented, Danny becomes dead-set on avenging him.
- Asshole Victim: Albert for Kit, Danny for James. Worth noting that out of all the Riders he had eliminated by that point, Danny was the only one he had felt guilty about venting.
- An Axe to Grind: Do we even need to say it?
- Blood Knight: After getting their Rider powers. This is best exemplified during the one time they ganged up on Kit despite being ordered not to by Xaviax.
- Bond Creature: Destwilder the tiger of Axe deck and Gigazelle the gazelle of Spear deck, respectively.
- Curb-Stomp Battle: Len makes a joke out of the Chos when they attempt to ambush him. They don't even get to transform.
- Even Evil Has Loved Ones: Despite being a pair of jerkish thieves they really care about each other.
- Jerkass: Even more than Mitsuru/Imperer (Albert's Ryuki counterpart) at his worst. They ganged up on Kit for little to no reason even though they were ordered not to by Xaviax among other things.
- Kick the Dog: The brothers are very quick to mock the state of Kit's father and the recently-vented Sting quite viciously. Kit does NOT take this well, as Spear found out the hard way the next episode. Guess who loses a loved one next?
- Non-Standard Character Design: Like Imperer, Spear is this as his armor colors do not match Gigazelle's colors. Spear's Rider Armor primary color is brown, while Gigazelle's primary color is purple.
- Panthera Awesome: Axe with his Advent Beast, Destwilder the tiger.
- Related in the Adaptation: Their respective Ryuki counterparts are not even partners in crime.
- Roaring Rampage of Revenge:
- Axe, after Kit vents his brother.
- Both of them do this in their story line of the video game because the other is vented. However, unlike the show, the target is Xaviax.
- Sibling Team: They fight in sync with each other as the two of them ganging up on Kit shows well enough.
- Sibling Yin-Yang: Danny is the stoic big brother to the younger hotblooded Albert. They both slide towards Stupid Evil, though.
- They Call Him "Sword": Both of them, obviously.
- This Is a Drill: Spear's Spin Vent.
- Wolverine Claws: Axe's Strike Vent.
- Zerg Rush: Spear's Final Vent.
Kase/Kamen Rider Siren
Portrayed by: Carrie Reichenbach, Voiced by: Miyuki Sawashiro (Japanese dub)
To the surprise of everyone, she's another survivor of Ventara. She's not happy with Kit's involvement at first, but she comes around (and Len wasn't much better at the start anyway).
Tropes associated with Kase/Kamen Rider Siren:
- Action Girl: Of course.
- Adaptational Heroism / Adaptational Jerkass: Zig-zagged. Her counterpart Miho is more of an Anti-Hero in Ryuki but was still very sympathetic. Kase made it her business to butt heads with Kit before she learned to respect him.
- Affirmative Action Girl: She is one of the best fighters among the Ventaran Riders. As Xaviax himself puts it:JTC: Another Ventaran Kamen Rider? She as good as Wing Knight?Xaviax: Maybe better.
- Arrogant Kung Fu Gal: To people she doesn't trust and/or doesn't think are worthy of being riders. She is actually quit amiable if she thinks you deserve it, though.
- Ascended Extra: Her counterpart in Ryuki only appeared in the movie and was killed off rather unceremoniously. Here, she plays a much bigger role.
- Badass Biker: Naturally. Kamen Rider, duh.
- Badass Cape: She has one attached to her shoulders in a similar manner to Wing Knight. Unlike Wing Knight's cape (which requires him to use Guard Vent or to be in Survive mode), her cape is permanent.
- Battle Couple: She makes good fighter duo with Len after all.
- Biker Babe: She is introduced getting of her bike and shares this trait with Len.
- Bond Creature: Blancwing the swan, Advent Beast of the Siren deck.
- Cool Sword: Her Weapon of Choice, a rapier that also serves as her card reader.
- Death by Irony: She was vented by Strike. In Ryuki, her Japanese counterpart Femme is the one who killed Ouja in the Episode Final movie.
- Distaff Counterpart: To Wing Knight. They are both fighters (among Ventaran's best), Badass Bikers, their cards readers also acts as a sword, and utilize Sugar-and-Ice Personality (cold on the outside and actually fairly nice on the inside). She also treated Kit the same as Len did early on.
- Sixth Ranger: To Kit and Len after she comes in and replaces Chris as the third rider in their team. Kit treats her like a come-lately intruder because she looks down on him and hogs all Len's attention for herself.
- The Smurfette Principle: Siren is the only female Rider out of 12.
- Swans A-Swimming: Both her motif and her Advent Beast.
- Take Up My Sword: Maya temporarily takes the reins as Kamen Rider Siren while Kase is in the Advent Void and recovering after being pulled out.
Vic Frasier/Kamen Rider Wrath
Portrayed by: Mark Cameron Wystrach, Voiced by: Hideo Ishikawa (Japanese dub), Hochu Otsuka (Japanese dub, under Xaviax's control)
A construction worker and one of Xaviax's kidnapping victims, and like the rest was drained of energy and put into a catatonic state. Xaviax can control his body to take part in the fight directly.
- Adaptational Badass: On one hand, Wrath is far more skilled as a fighter than Odin, as Wrath relies on his hand-to-hand combat skills (both with the Sword Vent and without it) more often than using the infamous Teleport Spam.
- This is noticeable when you compared Wrath's fight in episode 31 (which features Ryuki Stock Footage) compared to other fights that feature Wrath (all of them uses entirely original footage). Original footage of Wrath uses the teleportation powers just five times (the most being 3 times in episode 27), while the Odin Stock Footage that made it to Dragon Knight has him uses the teleportation powers twelve times.
- Adaptation Expansion: Outside of Ryuki's PlayStation game, Odin's full version of the Final Vent is never seen until Wrath does it in episode 31.
- Adaptational Wimp: On the other hand, while he is still the strongest Rider in KRDK, because Wrath isn't designed to be ludicrously overpowered like Odin, Wrath's fighting prowess is often matched by the more experienced Wing Knight and Siren, unlike Odin who is so overpowered compared to all the other Riders in Ryuki that every fight that Odin took part is a Curb-Stomp Battle for Odin, with only a miracle (Shiro finally realizing the Rider War is useless) stopping Odin from winning outright.
- All There in the Manual: Wrath's real name was never directly said in the series, but is found in official supplementary material along with his backstory.
- Badass Arm-Fold: Just like his Ryuki counterpart, Odin. Given that he is possessed by Xaviax, it fits.
- Bond Creature: Goldphoenix the phoenix, Advent Beast of the Wrath deck.
- Demonic Possession: Xaviax controls Vic's body directly.
- Dual Wielding: His Sword Vent.
- Flat Character: Well, not a whole lot of characterization is available when you're comatose and possessed.
- Hoist by His Own Petard: In addition to venting Kit, his Final Vent also vented himself.
- The Mentor: The original Wrath was this to Len. Xaviax wastes no time toying with him about it.
- Non-Standard Character Design: A small detail with his V-Buckle, as Wrath's the only one with a gold-colored one. This is shared with Odin as well.
- The Phoenix: His Advent Beast.
- Secret Weapon: Xaviax describes him as such.Xaviax: I kept one Kamen Rider back...for emergencies.
- Suicide Attack: Dragon Knight reveals Odin's Final Vent as this when Wrath performs it in episode 31.
- Sword Drag: A habit of his is to scrape his swords against each other, which creates Sword Sparks for added badass effect.
- Teleport Spam: Uses this to aid himself in battle. Unlike Odin however, he didn't take full advantage of this, as Wrath relied on his hand-to-hand combat skill more than fully abusing the teleportation powers.
- Two Voices, One Character: In-Universe-example in the Japanese dub, as Xaviax can switch between Vic's voice and his own at will.
Adam/Kamen Rider Dragon Knight I
Portrayed by: Stephen Lunsford, Voiced by: Tatsuhisa Suzuki (Japanese dub)
Adam was one of the Ventaran Kamen Riders, but became tired of the job. When a Karshian approached him and offered to release the Advent Deck's DNA lock, he jumped at the chance, only to realize too late it was Xaviax. Late in the invasion of Earth, Xaviax, running out of options, gave the reclaimed Dragon Deck back to Adam and ordered him to become a HeelFace Mole to the returning Ventaran Riders.
- Being Evil Sucks: Is clearly unhappy with how things turned out.
- Didn't Think This Through: According to Len and Eubulon (actually Xaviax in disguise), while Adam was a good fighter, and willingly volunteered to be a Kamen Rider, he apparently didnt consider the possibility that his Advent Beast link would be forever.
- Dragon Knight: Of course.
- Earn Your Happy Ending: He is given a normal life with Sarah after the final battle against Xaviax because he did the right thing in the end.
- Evil Twin: His alignment is more complicated that just 'evil', but is mostly considered this to Kit anyway as his mirror twin.
- The Farmer and the Viper: Ventaran Riders were willing to cut him some slack, even if very begrudgingly, and it nearly came to bite them in their collective rears. He had to betray them again and they would not know until it was too late if he didn't break down and spill the beans.
- HeelFace Mole: Xaviax blackmails him into being this to the returning Ventaran Riders.
- I Just Want to Be Normal: The cause of everything. He wanted to live a normal life even before Sarah came in. It wasn't very hard for Xaviax to take advantage of his desperation.
- Instant Awesome: Just Add Dragons!: Dragon Knight, duh.
- Kill It with Fire: His Strike Vent and Final Vent.
- Love Makes You Evil: He wanted to end his career as a Rider to be with a girl he loved. Unfortunately, Xaviax is pretty good at using love as a weapon.
- Not So Different: From Kit. Both were manipulated by Xaviax through someone close to them. Neither of them wanted to be a rider.
- Suicide by Cop: Unable to bring himself to Vent Len despite having a clear shot, he pleads for the others to vent him. They don't.
- The Call Knows Where You Live: His main gripe with being a Kamen Rider. He just wants a normal life.
- Unwitting Pawn: The first time he falls for Xaviax's manipulations. He knew the situation the second time over, but didn't have any other choice than to follow through.
- Acting for Two: Although they and their Earth clones never met.
- Back for the Finale: Everyone but Len, Price, Chance and Hunt. Kase recovers from her stint in Advent Void and others are pulled out of the Advent Void right into the last battle with Xaviax.
- Good Counterpart: They have similar personalities like their Earth twins but with some more or less minor differences.
- True Companions: What little is seen of their interaction suggests this.
- Last Episode, New Character: While the existence of other Ventaran Riders note besides Adam, Len, Kase, Chance, Pryce and Hunt is known, they appear only in the last battle against Xaviax in the second to last episode. This happens again in the novel.
Price/Kamen Rider Strike
Portrayed by: Scott Bailey, Voiced by: Tomokazu Sugita (Japanese dub)
- Evil Twin: The most notable example of dissonance between Earth rider and Ventaran rider. Price is disgusted after getting to know his mirror twin and saddened that Maya can't stand his appearance because of how he hurt her.
- Relationship Upgrade: He and Maya become Official Couple through the timeskip between the TV continuity and the novel.
- Sheep in Sheep's Clothing: He was initially suspected to be very much like JTC, but he is proven to be very different from him.
- Ship Tease: His last scene in the last episode has him hold hands with Maya.
Chance/Kamen Rider Torque
Portrayed by: Christopher Foley, Voiced by: Koji Yusa (Japanese dub)
- Superior Successor: Inverted. Chance isn't anywhere near the methodical fighter Drew is, preferring to either directly rush into the fray or only pelt enemies from afar with his Shoot Vent. His disinterest in mobility results in him being pinned down by monsters most of the time.
- The Gadfly: He likes to poke people, namely Price. It's all in good faith and nobody really minds.
Hunt/Kamen Rider Axe
Portrayed by: Mike Moh, Voiced by: Takahiro Sakurai (Japanese dub)
- The Cynic: He doesn't believe that Adam had fully reformed. He's right.
- Informed Loner: His anti-social tendencies do not prevent him from assisting his allies. His limited screen time implies that he is simply not one to chitchat or hang out with others.
- The Stoic: Is a quiet loner in contrast to the loud bully his Earth twin is.
Portrayed by: William O'Leary, Voiced by: Hochu Otsuka (Japanese dub)
The Big Bad, who is quietly abducting people one by one, until he can create a genetic database big enough to do mass kidnappings and enslave the human race. Something of a Master of Disguise; while he only has one human form, he's used it to pose as a lawyer, a mercenary, a federal agent, and so on. He's also transformed into Eubulon's human form and even duplicated his Kamen Rider armor, right down to the cards he uses.
Tropes associated with General Xaviax:
- Big Bad: The main antagonist of the series.
- Card-Carrying Villain: Unquestionably, unchangably evil and very much into it. That's where his Evil Gloating and Large Ham comes in.
- Deal with the Devil: His forte. He approaches people to offer them what want/need if they fight for him. He would hold his end of the deal or at least he did in Adam's case.
- Evil Cannot Comprehend Good: He thought that he can manipulate Kit exactly like he did Adam, never considering that Kit may decide differently because he is not his mirror twin and has his father's advice.
- Evil Gloating: Indulges into this to show the Riders they can't beat him. They did anyway, obviously.
- Faux Affably Evil: Going hand and hand with his Manipulative Bastard abilities, he typically acts like this. A logical requirement for his M.O.
- The Heartless: A literal example as he is stated not to have a heart.Xaviax: [commenting on Kit refusing a Deal with the Devil] Some boys are just heartless.(presses down on his chest where he would have a heart as if he were a human)JTC/Strike: [what the hell expression] General, you don't have a heart.Xaviax: [stops pressing with an "oh, right" face]
- I Control My Minions Through...: Most of the Riders he sics on the heroes are shackled to him through Obligation to whatever Deal with the Devil he's made; though he'll fall back on good old Fear if he has to. JTC is the only Rider that chose to follow Xaviax and that's only out of self-preservation.
- I Have Many Names: has a moment of this when meeting Kit face to face to offer him a deal.Xaviax: I've been many things. Brad Barrett knew me as Charlie Feathers, Chris Ramirez thought I was Agent Simons, and the kid you knew as Kamen Rider Camo called me Captain Mattock.Kit: Xaviax!
- Large Ham: He may be one of the very reasons why many watch this show.
- The Greys: His true form resembles one of these.
- Manipulative Bastard: Most of the Riders are only working for him because he played them like fiddles.
- Man of Wealth and Taste: Dresses in smart business suits for many of his aliases, and his default outfit is a black coat with an upturned collar.
- Nice Job Fixing It, Villain!: He wakes Frank Taylor up for a while to give Kit a glimpse of what would he get if he took up his offer. This allows Kit to indirectly ask his father for advice, which then gives him strength to go defy Xaviax.
- Not-So-Well-Intentioned Extremist: Between his methods and the fact that he wants to rebuild the planet he himself destroyed using slave labor, Xaviax definitely counts as this.
- Orcus on His Throne: He prefers to recruit people to fight for him and sends monsters to kidnap victims for his plans despite having all the means to get things done with little effort and time. This comes to bite him when he runs out of riders (most of them anyway) and toying with Kit backfires.
- Shapeshifter: Can shapeshift into any form he desires.
- Shape Shifter Default Form: His human form is merely a disguise, his true form is only glimpsed before his demise and resembles a Grey alien.
- Smug Snake: Nothing short of the Ventaran riders charging up their collective final attack can shake up his confidence. Otherwise, he is always in control, above the situation.
- Surrounded by Idiots: He feels like this about all earth riders that are not Strike.Xaviax: [about the Cho Brothers] Very enthusiastic. Not bright, but enthusiastic.
- This Was His True Form: Moments before his death, he reverts back to his true form likely due to putting all his power into trying to protect himself from the Link Vent.
Portrayed by: Jeff Davis, Voiced by: Rikiya Koyama (Japanese dub)
Lonely, hardworking man and Kit's father. The death of his wife left him to deal with running household, making a living and rising his only son all alone.
- Disappeared Dad: He is to Kit, as he vanished year before the start of the story.
- Empty Shell: Ended up in a vegetative state due to Xaviax's machinations.
Portrayed by: Yvonne Arias (credited as Aria Alistar), Voiced by: Yuria Haga (Japanese dub)
An Intrepid Reporter who writes for a paranormal blog. While investigating the rash of mysterious disappearances and the armored vigilante reports, she briefly is pulled through a mirror, allowing her to see Xaviax's monsters. She teams up with Kit to compare notes and figure out just what's going on. Much later, she temporarily takes Kase's place as Kamen Rider Siren, while Kase is stuck in Advent Void/recovering from being pulled out.
Tropes associated with Maya Young:
- Conspiracy Theorist: Works for a paranormal website, Way Above Top Secret.
- Intrepid Reporter: Related to her work.
- Non-Action Girl: And elects to remain so even after a taste of Action Girl-hood.
- Official Couple: With Price in the novel.
Portrayed by: Taylor Emerson, Voiced by: Yūki Kaji (Japanese dub)
Maya's coworker in the bookstore and the paranormal business. Might or might not have a crush on Maya, which might have contributed to his initial distrust of Kit and the Riders. After getting involved with the Riders, he's given a decision: join the No Men or go to jail. He chooses the No Men.
- Agent Mulder: He doesn't have any problem with believing in whatever oddness is going on.
- Conspiracy Theorist: Unlike Lacey, he belives Maya pretty much immediately.
- Hollywood Nerd: Trent is fairly normal person (no outside signs of geekiness as per the hollywood rule) besides his Agent Mulder tendencies. He is not even obssesed with comics or video games. Maya and Lacey mostly treat him as weirdo because he will go along with any weird scheme and plays Dungeons And Dragons.
- "Get out of Jail Free" Card: He is not in jail, just threatened with it. The No Men give him two choices: join the No Men or go to prison for breaking into their network (and not only that).
Portrayed by: Marisa Lauren, Voiced by: Yuka Komatsu (Japanese dub)
Maya's Valley Girlish and spunky best friend. At first tolerant of her friend's apparent Conspiracy Theories, she becomes increasingly frustrated and concerned as Maya and Trent delve into the Kamen Rider world. She eventually witnesses Riders in person, which unnerves her and leaves her open to manipulation by Michelle, but she ultimately sticks by her friends even though she's still uneasy with all the weirdness.
- Agent Scully: She doesn't believe a thing. First, it seems to her that Maya and Trent are playing something like a role-play in their pursuit of Kamen Riders. It goes from there to her thinking that Maya is just delusional and actually fearing for her.
- All Girls Want Bad Boys: Her reaction to Maya getting involved with Kit.
- Genki Girl: Played up in the Japanese dub (but of COURSE!)
- My God, What Have I Done?: Her reaction after turning over Maya's information on Kamen Riders to Michelle leads to Kit being captured by the No Men.
- Opt Out: Steps out during the final episodes, having trouble coping and not being able to contribute much.
Portrayed by: Kathy Christopherson, Voiced by: Youko Soumi (Japanese dub)
One of the senior reporters for the blog Maya works for. Generally bitchy and condescending to everyone, she often steals credit for stories and tries to undermine Maya when she won't play along. However, we eventually find that this is a cover, and she's actually a government agent for a top-secret paranormal division called the "No Men". After she successfully gets Maya's intel, the No Men start getting involved in the Rider war, ultimately becoming allies. And Michelle starts reining in her bitchiness, too.
- Good Is Not Nice: Her goals are heroic, her methods... not so much.
- Kick the Dog: When Maya won't share what she knows, Michelle goes ahead and steals the data. She eventually loosens up and apologizes.
- The Men in Black: Her employers.
Portrayed by: Mark Dacascos, Voiced by: Tsuyoshi Koyama (Japanese dub)
The Advent Master, only one with the power to reassign Advent Decks and retrieve defeated Riders from the Advent Void (originally intended to be a safe zone for them, not a prison). He was originally Xaviax's top scientist, but had a HeelFace Turn and developed the Rider system for Ventara. When defeated in Ventara, he was accidentally sent to Earth instead of to the Void.
- Adaptational Heroism: Let's just say that his Ryuki counterpart was not a nice person.
- The Atoner: He created the Advent decks for Ventaran people to protect themselves as a way of atoning for the world he devastated earlier.
- Badass Longcoat: He's got one, and he's definitely badass.
- Big Good: To the Ventaran riders.
- Defector from Decadence: He fell ill after arriving on Ventara. A local family took him in and nursed him back to health. He decided that saving his own planet by destroying another one is wrong and started a plan to help the afflicted.
- HeelFace Turn: In his backstory as mentioned above.
- Hope Bringer: As the only person capable of operating the Advent Void, he could make it so that being sent there wasn't permanent.
- Roswell That Ends Well: The alien landing in Roswell was him being sent there instead of to the Advent Void.
- Warrior Therapist: Acts as one for Len at the start of episode 35.Eubulon: So ask yourself: do you know it in your head, or just your gut? You're a great fighter, Len. But you have to be more than that to be a great warrior. Sometimes listening is harder than fighting. A true warrior must do both.
Colonel David Stuart/Kamen Rider Onyx II
Veteran of Afghanistan initially allied with the No Men. In reality, he only worked together with them to further his own plans of world domination. He collected the power of all decks and both Survive Modes to become Onyx Oversurvive. This eventually cost him his life.
Tropes associated with Colonel David Stuart:
- Blatant Lies: Declaring he doesn't want to use rider technology for military to dissuade Kit from being Properly Paranoid.
- Cruel and Unusual Death: He was hunted down by his Advent Beasts after breaking the contract.
- Man Behind the Man: The organization he is implied to actually work for.
- Manipulative Bastard: He got everyone wrapped around his finger and moved to positions in his plan. He convinced the No Men to let him in on the Kamen Rider business, fooled Master Eubulon into trusting him with the Advent Decks and knew the exact way to manipulate several earth riders into returning.
- Mythology Gag: The way he died is similar to how Masashi Sudo/Kamen Rider Scissors is killed in Ryuki, as Sudo ends up being eaten alive by Volcancer after his Scissors deck is broken into pieces by Ren's Final Vent.
- Him gathering all the advent decks is similar to one of the SIC Hero Saga stories in Ryuki, where Ouja was able to hijack all the Advent beasts into one massive Contract Monster, Genosurvivor.
- Lastly, him fighting 12 riders at once is similar to the 13 Riders special of Ryuki, where Shinji fights all the other riders save for Raia, Scissors, and Knight (the former two having been killed at that point, and Knight having been fatally wounded, passing on his deck to Shinji.
- Old Soldier: He is decribed as old, but by no means weary or weak as he still stands with both the strength and authority of professional soldier. This is further punctuated when he uses the Onyx Deck and fights 12 Riders at once.
- Patriotic Fervor: Vile example of Patriotism is bad. He believes that USA will save the world by conquering other nations with military force.
- Shell-Shocked Veteran: His war experience helped scatter his marbles.
- Stealth Hi/Bye: Just the arrival part. He often appears out of nowhere through the course of the story. He stole the Onyx deck and became a Kamen Rider, thus making him able to travel through mirrors.
- Throw the Dog a Bone: The tactic he uses with Chris, who got better from his days as depressed woobie, but still is very easy to manipulate through acknowledgement and praise. He praises Chris on his achievements as soldier and Kamen Rider and his family for being good soldiers. This is all that's needed to convince him to return as Kamen Rider Sting.
- Well-Intentioned Extremist: In a similar vein as Xaviax. He wants to save his war torn homeworld, but unlike Xaviax who have went on destroying other worlds, Stuart would wreck his own in the procces.
Brian Mace/Kamen Rider Wing Knight IILen's mirror twin who works for Colonel Stuart. He impersonates Len, fooling Kit into working with him.
Tropes asociated with Brian Mace:
