Characters: Kamen Rider Gaim Yggdrasill Corporation
Yggdrasill is a powerful corporation that manages and controls Zawame City.
- Arc Villain: They are the main antagonists of the Yggdrasill and Helheim Saga.
- Big Brother Is Watching You
- Disc One Final Boss
- Enemy Civil War: After Takatora is betrayed the companies inner circle rips itself apart.
- Evil Versus Evil: Them versus the Helheim Forest.
- The Guards Must Be Crazy: Yggdrasill is pretty much hyper-competent about everything except with their security detail. The guards forget to watch the cameras, the executives never turn off or log out of computers with sensitive information, and the Kurokage Troopers spectacularly fail during critical moments: Not only can they be tricked by simply making a sharp turn; they manage to let three targets escape while not landing a single hit with their cannons. And let's not get started on how a 16-year-old flying a Dandeliner for the first time does a better job than the mooks specifically trained for it...
- "It" Is Dehumanizing: Many members of Yggdrasill call the Armored Riders 'guinea pigs'.
- Kill It with Fire: Whenever the Helheim Forest encroaches onto Zawame City Yggdrasill puts a stop to it with a copious amount of fire.
- The Masquerade: Yggdrasill is all over the place with this from making people think that the Armored Riders are a new fad to covering up the Helheim Forest's existence and stopping it from encroaching onto the human world.
- Meaningful Name: One of the show's many references to Norse Mythology.
- Omniscient Council of Vagueness/Not-So-Omniscient Council of Bickering: Yggdrasill's inner circle is somewhere in between these two tropes. While they know a lot more than anyone else about what's going on; it's clear that they don't know everything, they're barely able to get along, and Takatora admits that they can barely control the Helheim situation.
- Renegade Splinter Faction: One led by Professor Ryoma that has pretty much completely taken over the organization with Takatora as the only Rider that's not a member of Ryoma's nut club.
- Self-Disposing Villain: Yggdrasill basically defeated itself: after Takatora was apparently killed, the other New Generation Riders proceeded to rip the organization into pieces, allowing Redyue to easily conquer its main headquarters. The final nail in the coffin was when Ryoma revealed the secrets of Project Ark to the whole world. Honestly, Kouta could have sat on his ass twiddling his thumbs and waited for Yggdrasill to implode on itself.
- Supervillain Lair: Yggdrasill Tower. It lords over Zawame City, has a permanent portal to Helheim in it, is heavily armed with laser guns, has an Invisibility Cloak to stop the populace from realizing anything weird is going on, and possesses the Scalar System, a WMD that can destroy the entire city and kill everyone in it. From #32 onward the building is used by the Overlords as their landing site on Earth, making it their own Supervillain Lair.
- Villains Want Mercy: In #11 when the Yggdrasill camp is being overrun by Inves, one of the scientists begs Kouta for help despite laughing and talking about how the Beat Riders are just guinea pigs before. Kouta calls him out on being a Hypocrite, but still helps save the day.
- Villain with Good Publicity: Yggdrasill encourages the popularity of the Inves Game by distributing Lock Seeds, hands out Drivers to kids as part of their shady experiments, and later frames them for the outbreak of the Inves Plague. Granted, #16 hints that Yggdrasill might not be so villainous after all, as their means might be justified to save humanity.
- The World Tree: Evoked in their name, which ties into the whole "fruit" themenote . Their headquarters is even a tree-shaped tower.

Takatora Kureshima/Kamen Rider Zangetsu (Shin)
Takatora Kureshima/Armored Rider Zangetsunote /New Generation Rider Zangetsu Shinnote
Portrayed by: Yuki Kubota (live), Jun Watanabe (suit)
"This world is full of evil. Evil beyond purpose or reason."
The older brother of Team Gaim's Mitsuzane Kureshima. As an heir to the Yggdrasill Corporation, he has already taken on responsibilities within the company and is currently the head of the R&D Department. Though ruthless, he loves his brother dearly.
He initially uses the Melon Lock Seed and the Sengoku Driver to transform into Armored Rider Zangetsu. Later, he becomes the first user of the next-generation Genesis Driver, which, along with the Melon Energy Lock Seed, allows him to transform into New Generation Rider Zangetsu Shintl
- All According to Plan: According to him, Gaim getting the Sengoku Driver has advanced Yggdrasill's agenda in some way.
- Shown in #12: the various Riders using the Sengoku Driver has allowed Yggdrasill to both mass produce Drivers in the "form" of Kurokage for their mooks, and allowed the creation of both the Genesis Driver, and Energy Lock Seeds.
- All There in the Manual: Neither of his Rider names have been spoken in the show. He's only ever referred to as "the white Armored Rider".
- Aloof Big Brother: Is Ryugen's big brother, but instead of participating in the conflict between Beat Riders, he works for that big shady company.
- Anti-Role Model: He comes to consider himself one. He thinks he provided a poor example for Micchy and unintentionally inspired him to become the ruthless, two-faced villain he is today after he was so easily fooled over the course of the series.
- Anti-Villain -> Anti-Hero: He has been shown to have standards, loves his brother, is genuinely well-intentioned, and is the only member of the inner circle that hasn't gone out of his way to be a dick in some way.
- He is very uneasy about his decisions and wants Kouta to despair out of the belief that it would validate Takatora's own actions.
- He eventually develops a high opinion of Kouta, and is willing to work with him when a more idealistic alternative to his original plan presents itself. While Takatora is willing to go to dangerous extremes, he is ultimately well-intentioned and firmly committed to saving humanity.
- Arrogant Kung-Fu Guy: Has the arrogance down, most likely due to his wealthy upbringing and role in Yggdrasill's grand plan. His combat ability is unquestionable.
- Authority Equals Asskicking: Is a high ranking member of the Yggdrasill Corporation and strong enough to causally deliver a Curbstomp Battle to Gaim.
- Authority in Name Only: While he's supposedly The Leader and Big Bad of the New Generation Riders none of them actually follow his commands and really defer to Professor Ryoma.
- Badass: Nearly killing Gaim is the least of his accomplishments to put it lightly. He is the strongest Rider, leaving everyone else really far below him.
- Beneath the Mask: At first glance Takatora is a stoic, arrogant man, but underneath it all he hates himself for what he plans to do but genuinely sees no other choice.
- Big Bad: Subverted. While presented as the major enemy at first, as the show goes on he's shown to be neither very Big (other forces can easily manipulate him) nor Bad (he's committing what he feels are Necessary Evils).
- Big Brother Instinct: For all of his faults, Takatora does genuinely care about his brother's future and well-being.
- He did not take Sid's suggestion that Micchy took the Watermelon Lock Seed well.
- His reaction to finding out Micchy is an Armored Rider... was not very good. He then also put two and two together about the Suika Lock. An episode later, he angrily demands answers out of Sid as to why he gave his brother one of the Drivers. When he confronts Mitsuzane about it, he even outright admits that he's upset because he wanted to protect him from the entire conflict with Helheim.
- Bishie Sparkle: How he's seen through Bravo-Vision.
- Break the Cutie: Takatora wants to do this to Kouta. A rare example where he doesn't really want to do so out of outright hatred or malice, but because he has genuine doubts about his actions and Yggdrasil's agenda. Takatora believes that seeing someone as heroic and idealistic as Kouta back down from challenging him would help ease his conscience and prove his course of action to be correct.
- He also unintentionally did this to his own brother. Takatora showed Micchy the truth about the Helheim Forest in order to convince him to join Yggdrasil and help Takatora. However, it ended up causing Micchy's Start of Darkness.
- Break Out the Museum Piece: In #36 he regains his old Sengoku Driver to become the original Zangetsu to try to finish things with his brother.
- Break Them by Talking: He breaks Kouta in #22 by showing Kouta's fight against Yuuya and pointing out how everything worked out because he killed his friend.
- Broken Pedestal: To Ryoma in a really weird way. Ryoma used to hero worship Takatora, seeing him as the next God Emperor of mankind. However, after finding out that Takatora wants to use his powers for altruistic reasons, he turns against him.
- Cain and Abel: Abel to Mitsuzane's Cain.
- Character Development: Takatora started out as an arrogant man who saw the Beat Riders as "street trash" but as he fought Kouta his arrogance wanes and he develops respect and sympathy for them.
- Comes Great Responsibility: He believes that it is the duty of the rich and powerful to protect the weak, even referring to it as Noblesse oblige.
- The Comically Serious: Becomes this when interacting with Bravo.
- Corporate Samurai: An almost literal example, since his armor as Zangetsu has a distinctly Japanese motif.
- Create Your Own Villain: He considers himself the one who turned Micchy into the scumbag he is today.
- Curb-Stomp Battle: Delivers one to Kouta in #4, then curb-stomps all five other Riders in #11.
- Does it again in #12 when testing the Genesis Driver against a squad of Kurokage mooks. It appears that "Curbstomp" is his default setting.
- #14 has him do this once again to Baron. However according to him, the Sengoku Drivers and Base Riders can't hope to equal an New Generation Rider.
- In #19 this happens again: Kouta holds out for a while but ultimatley couldn't touch Takatora at all.
- Cuteness Proximity: His reaction to Ichigo Arms in the Hyper Battle Video.
Takatora: This is too cute for me.
- Dark Messiah: In direct contrast to Kouta.
- Disney Death: In #28 Takatora "dies" by being thrown off a cliff. To no one's surprise he's shown to be alive the very next episode.
- Zigzagged in #36, where Mitsuzane blasts him into the river and wrecks his Driver. Normally in Kamen Rider, being thrown into the water is the result of a harsher-than-usual beatdown, but it's generally not fatal. But then he's not seen (other than as a hallucination) for at least six weeks...
- Did We Just Have Tea with Cthulhu?: In #29 Takatora meets Roshuo, King of the Overlords, who saves his life and regales him with his life story.
- Does Not Like Guns: Zigzagged. He prefers katanas over guns, despite his Musou Saber doubles as a gun.
- Dramatic Irony: In #20 he makes a speech about how one evil person can ruin the hard work of a hundred virtuous efforts... cue a scene where the rest of the New Generation Riders gleefully admit that they plan to screw Takatora over when the time is right.
- The irony is furthered in the following episodes: he accuses Kouta of being naive, but Takatora now seems to be the only major player who doesn't realize that his associates are planning to betray him, as well as being the only major character oblivious to the existence of the Overlord Inves.
- Takatora genuinely cares about and wants to protect his brother, but showing Mistuzane the truth about the Helheim forest and bringing him into Yggdrasil has set the latter on the path to outright villainy.
- The Dreaded: Kouta is scared to death of him. And after #11, this also applies to everyone but Micchy and Oren.
- Even the other New Generation Riders fear him. When the time comes to betray him, Minato is actually cautious and after his supposed death Sid feels confident enough to betray Ryoma.
- Education Mama: Male example. He continuously reminds Mitsuzane about the importance of his education and advises him to avoid any "distractions" in his life.
- Et Tu, Brute?: In #28, after getting betrayed by Sid and then Minato, Takatora applies this trope on Ryoma (who he honestly saw as his closest friend) when he finds out that the scientist is part of the coup.
- Even Evil Has Loved Ones: The term evil may not be the right word for him, but Takatora does genuinely love his younger brother and wants what is best for him. In the two earliest tie-in films, he even sides with Mitsuzane and the other Armored Riders in the conflicts.
- This comes to bite him back in the ass in the most tragic way possible and leads to his supposed demise.
- Even Evil Has Standards: He openly says that a trained soldier having a Sengoku Driver is too dangerous during #7 and requests the Driver be returned. Everyone else, however, seems to entertain the idea of Oren having the belt in one way or another.
- He shows disgust whenever his other members do things For the Evulz.
- He also doesn't aim to kill when fighting other Armored Riders. In #15, he makes it clear that without their belts the Beat Riders should even be protected. Unfortunately Sid seems to disagree...
- After Takatora breaks Kouta by revealing the truth about Yuya's death to him, he simply lets him go since he doesn't think he's a threat to Yggdrasil's plans anymore. This is in spite of Sid's skepticism and the fact that he could probably kill Kouta easily in is depressed state.
- Every Scar Has A Story: Has a prominent one on his right shoulder, inflicted during his first transformation into Zangetsu. #27 reveals that it still very much hurts, meaning that he has been fighting with a handicap the entire time.
- Evil Counterpart: To Kouta, big time. Both are the lead characters in their respective factions and noticeably more moral than the other Riders - in fact, the only real difference between them is that Zangetsu has accepted having to Shoot the Dog; Gaim hasn't. As for their Rider forms, they're not only both samurai; but they both have the Musou Saber as an extra sidearm and their armors are in many ways Palette Swaps of one another.
- Later subverted; Takatora's not evil, he's just more cynical. As soon as Kouta shows him the potential for a more idealistic solution, he's all in.
- He's initially presented as one to Micchy. Both brothers come from a rich and powerful family, but while Micchy is friends with the hero, Takatora is built up as a villain. However, it's eventually inverted: Takatora ultimately has selfless motives and a strong moral compass, while Micchy is extremely selfish and becomes more and more twisted.
- Exact Words: Zangetsu was compared as the Ouja of the series. Turns out they weren't talking about THIS Zangetsu...
- A Father to His Men: Shown to genuinely care for the mooks directly under his command.
- Foil: Takatora is one to both Kouta and Micchy.
- Kouta: Takatora is The Cynic while Kouts is The Idealist. Both men are ultimately well-intentioned and want to protect humanity. Takatora is willing to commit various atrocities in order to make sure that the human race is able to survive; Kouta remains steadfast in wanting to save everyone and disapproves of Yggdrasil's methods. However, the two eventually realize they are Not So Different and Takatora is eager to take a more idealistic alternative when it presents itself.
- Mitsuzane: Takatora is originally hinted to be a Big Bad, but is ultimately revealed to be a Well-Intentioned Extremist who genuinely wants to protect humanity and doesn't desire power for himself (even believing that it is the duty of the powerful to protect the weak). In addition, Takatora gradually warms up to Kouta and is moved by his idealism. In contrast, his brother Mitsuzane undergoes a Face-Heel Turn as he becomes increasingly Drunk with Power, to the point that he doesn't care about anything except what he personally wants. He joins forces with Redyue in her invasion of Earth even though her success would most likely bring about the end of human civilization. While he's also initially best friends with Kouta, Mitsuzane becomes bitter and hateful when Kouta's idealism leads him to repeatedly (and unintentionally) defy Micchy's schemes, and he starts trying to kill him.
- It gets worse: when Takatora was willing to carry out Project Ark, he honestly saw it as a Necessary Evil and felt immense guilt for planning to carry it out. Once the possibility of a more idealistic option presented itself, he eagerly took it and joined forces with Kouta. In contrast, when Mitsuzane starts carrying out his own version of Project Ark in #35, he doesn't seem to express any sort of remorse; he gives some lip service to it being the key to humanity's survival, but he doesn't seem to actually care that massive amounts of people will die. Even worse, he treats Kouta's idealism with nothing but hatred, seeing it as a threat to his plans that needs to be destroyed.
- Four Is Death: His Melon Lock Seed is LS-04, while his Melon Energy Lock Seed is ELS-04.
- Four-Temperament Ensemble: The Melancholic.
- Good All Along
- Happily Married: In the Soccer World, he has a sick wife, paralleling him with Roshuo and his queen.
- Hero with an F in Good: Oh, holy God yes. Every attempt he's made to try to stop Helheim has either shifted power back towards the people trying to manipulate him or somehow ended up making the entire situation worse for both sides.
- Heroic BSOD/Despair Event Horizon: Happens in #28 after he realizes Ryoma has betrayed him he loses the will to fight.
- Hidden Agenda Villain: Kept his plans hidden for a significant portion of the story.
- Hidden Depths: During his Curbstomp Battle with the other Riders, he takes extra caution to not actually kill anyone, even Oren who he thinks shouldn't be a Rider, by holding his Musou Saber backwards. He's actually horrified when he winds up destroying one of the Sengoku Drivers.
- Furthermore, he tried to stop Ryoji from eating a Helheim Fruit, and after his transformation, he made Sid take him down in order to try to make him feel responsibility for his actions.
- In #21, he admits that he has genuine doubts about his more morally questionable actions and Yggdrasil's plans, and respects Kouta's heroism and resolve.
- #36 shows that he's not as cold and absolute as one may think. He fails to deliver the final blow on Mitzusane and is coldly struck down because of his hesitation.
- Horrible Judge of Character: This is one of Takatora's Fatal Flaws. He relies on some rather Obviously Evil people, and can find no wrong in his brother. Micchy outright states that Takatora has a habit of trusting people that he really shouldn't in #23.
- Imaginary Enemy: Micchy starts seeing hallucinations of Takatora after defeating him.
- It's All My Fault: Takatora blames himself for what Micchy has become in #36.
Takatora: That's right. I'm the one who made Mitsuzane like this.
- The Juggernaut: The only thing that's ever stopped him was his own moral compass, if he wasn't a good man, the bad guys would have won a long time ago.
- Knight of Cerebus: In-universe for Kouta. Once he shows up in his life, he stops taking his life as an Armored Rider as a game.
- Kubrick Stare/Perpetual Frowner: His default expression.
- Large Ham: Minor example: Though we the audience only see it once, his pre-transformation pose as Zangetsu is the most grandiose of all the Armored Riders, using CGI even before the transformation is initiated. He does no pose or gesture as Zangetsu Shin, however.
- Laser-Guided Karma: He's the one who showed Mitsuzane the truth of Helheim and therefore started his downfall. It makes sense that he'd die from the end result's hands.
- Locked Out of the Loop: By #23, he had become by far the most unaware major player. He didn't realize that his associates were plotting behind his back, and he was the only major character who didn't know about the Overlord Inves.
- Man in White: As Zangetsu.
- Mid-Season Upgrade: Melon Energy Arms
- Multiform Balance: Titled "Arms".
- Personal Arms:
- Borrowed Arms:
- Named After Someone Famous: After Toudou Takatora.
- Necessarily Evil: How he perceives all of the morally unjust things he does. He still feels immense guilt for them, though.
- Nice Job Breaking It, Hero: Attacks Bujin Double right as he was about to finish off Bujin Gaim, resulting in Double's defeat, thinking Bujin Gaim was the Gaim he knew. While he wasn't exactly a 'hero' at the time, he was still on the hero's side during the conflict at hand.
- No-Holds-Barred Beatdown: Gives Kouta one so brutal in #4, it leaves the poor guy absolutely terrified of him.
- Not so Above It All: In #22, he chuckles before showing Kouta that he killed Yuya.
- Not So Different: Both Takatora and Kouta have doubts about fighting the Inves, care for those close to them, and ultimately want to protect people; the key difference between them is that Takatora has accepted the idea that innocent people must be sacrificed for the greater good, while Kouta wants to save everyone.
- Takatora purposefully tries to invoke this on Kouta: when Kouta calls him out on being willing to sacrifice lives in #22, Takatora turns it back on him by explaining that Kouta and other people are only alive today because he took Yuya's life. However, Kouta soon regains his resolve, rejects Takatora's belief, and destroys Yggdrasil's Scalar System with Kachidoki Arms.
- In #27, his backstory reveals his goal to save as many people as possible from the Helheim invasion, similar to Kouta. Both of them also have a villainous sidekick that they genuinely view as their friend, while their sidekicks have their own goals and are willing to betray them any time (Ryoma to Takatora, and Micchy to Kouta).
- Offscreen Teleportation/Villain Teleportation: Demonstrates this ability in Helheim Forest in #4.
- Only Sane Man: For Yggdrasill. He's the only one who hasn't done something solely For the Evulz and is focused on their main objective while the other members of the inner circle tend to prefer making the Armored Riders suffer for fun.
- Becomes more pronounced as time goes on: Takatora is the only New Generation Rider who actually wants to save humanity and acknowledges that Yggdrasil's actions are cruel; the others all see the Helheim invasion as a good thing and don't care that their plans will cause the deaths of billions.
- Parental Substitute: Takatora admits in #36 that because their parents were always overseas, he had to raise Mitsuzane.
- The Proud Elite: Repeatedly refers to Beat Riders as "street trash" that's beneath him and tries to pass this attitude on to Mitsuzane. He got better after a while.
- Psychotic Smirk: Flashes a Sid-worthy one when he shows Kouta that he killed Yuya.
- Reasonable Authority Figure: Unfortunately, none of his subordinates are what you'd call "reasonable".
- Rain of Arrows: Assuming the abilities shown of the Sonic Arrow aren't shared by all New Generation Riders, Zangetsu Shin's arrows can do this, as shown in #12.
- Sensitive Guy and Manly Man: Manly Man to Mitsuzane's Sensitive Guy.
- Selective Obliviousness: This is Takatora's other Fatal Flaw: he tends to ignore whatever challenges his worldview or inconveniences his plans unless he can't avoid it anymore.
- He initially refused to consider the idea that his beloved little brother wasn't the stoic, diligent student he pretended to be and fails to notice that showing Micchy the truth about Helheim has had a very horrifying effect on his sanity.
- He fails to realize that all his trusted allies aren't Well-Intentioned Extremists like him and are conspiring against him. By #23, he appears to be the only major character who hasn't figured out that they're Obviously Evil.
- He's also so far into the "sacrifice the many to save the few" plan (in spite of the guilt it brings him) that he has trouble accepting anything else. Takatora also assumes that his allies are all just as dedicated to the plan as he is.
- Played for Laughs in the ToQger crossover, when he's completely oblivious to a giant mecha battle going on outside his window.
- Shirtless Scene: In #27, his bare shoulders and part of his back can bee seen during a shower scene. It shows that Every Scar Has A Story.
- Skilled, but Naive: While he's not technically naive, he's a very oblivious person due his tendency of relying on some extremely untrustworthy people and his inability to notice his brother's downward spiral.
- So Proud of You: To Mitsuzane's shock, he actually applauds him for going behind his back and going against his planned out life by telling him that "you definitely have Kureshima blood in you".
- Sympathy for the Hero: He seems to have gained a soft spot for Kouta, admiring his resolve and idealism, despite setting out to break his will.
- Upon meeting Demushuu and having Kouta tell him the truth about the Overlord Inves, Takatora immediately believes Kouta and the two join forces. Despite Kouta destroying the Scalar System, he seems to be more than willing to let bygones be bygones and give Kouta's idealism a chance.
- Eventually, Takatora develops a very high opinion of Kouta and genuinely wants to help him. Unfortunately, Micchy has other plans.
- Take Up My Sword: In #28, right before Sid sends Takatora plummeting to his doom, Takatora sees Mitsuzane in the distance and tells him to help Kouta and save humanity. Too bad Takatora doesn't know his little brother has made a Face-Heel Turn.
- Tall, Dark and Handsome
- Throwing Your Shield Always Works: Demonstrated in #11 when fighting against Ryugen.
- Token Good Teammate: Though ruthless and rather amoral in his methods, he's the only one of the New Generation Riders to have humanity's best interests at heart.
- Totalitarian Utilitarian: A PG version, with some similarities to Kiritsugu Emiya.
- Unwitting Pawn: To Sid, Ryoma, and Yoko, who all want Helheim to invade and are using Takatora to become stronger.
- Used to Be a Sweet Kid: With Micchy during his childhood days.
- Useless Protagonist: Micchy accuses him of being useless without Yggdrasil.
- Weapon of Choice:
- Personal Arms:
- Borrowed Arms:
- Well-Intentioned Extremist: Identifies as one, as he claims his plans are all for the good of helping humanity. He also goes on to say all of Yggdrasill is this, as it is their role in the world.
- #16 shows that whatever he is trying to do is meant to save the world and has something to do with what's at the heart of the Helheim Forest.
- Confirmed in #20. Takatora is trying to prevent Helheim from spreading over the earth, and in #21, if he has no other option to stop the spread, they use the ring on the tower to destroy all of Zawame. Sid, when revealing the latter to Kouta, pretty much states that it's a necessary evil if it means saving mankind.
- What the Hell, Hero?: Gets called out by Micchy in #36 for being oblivious.
Micchy: All you ever did was order me about, without ever seeing the bigger picture. And now you come waltzing back in!?
- Where Did I Go Wrong?: He asks himself this in #36 after he sees how far the brother he helped raise has fallen.
- World's Best Warrior: It's pretty much agreed upon by both the Beat Riders and Yggdrasill that he is impossible to beat one-on-one. Case in point? It took every other New Generation Rider working together to beat him, and even then Ryoma implied that, had Takatora not been knocked off balance by Ryoma's betrayal, he still might have won.
- Would Be Rude to Say "Genocide": G-Rated version. Yggdrasill does not "control" Zawame City, they enhance and improve it.
- And of course, he never uses the actual G-word when discussing killing six-sevenths of the world population.
- Workaholic: Shows shades of this. When he's not working, what little interaction he has with his brother is interrupted by his phone ringing. He also shows disgust towards most of the youth of Zawame City and especially the Beat Riders, since in his eyes they contribute nothing to society.
- Wrong Genre Savvy: Believes he's in a Cosmic Horror Story and that only through sacrifice would anything be achieved. In short, he thinks he's in a Gen Urobuchi story. He's not too far off the nose with the former, but Kouta shows him that the latter is not true.
- Yank the Dog's Chain: Takatora was actually happy in #28, smiling and basically acting like an adult Kouta. Cue his brother and comrades' completely unexpected betrayal.
- You Have Outlived Your Usefulness: After the Genesis Driver is finished, he declares that Yggdrasill has no need for the Armored Riders and plans to make them "face reality". Thankfully, he takes a non-lethal approach (in contrast to his allies).
- Takatora is on the receiving end of this trope when his allies finally betray him in #28.
Ryoma Sengoku/Kamen Rider Duke
Ryoma Sengoku/New Generation Rider Duke
Portrayed by: Tsunenori Aoki (live), Kenji Tominaga (suit)
"I think I can go higher. More powerful; more versatile; power worthy of a god."
A scientist working in the R&D Department of Yggdrasill under Takatora. He is the creator of the Sengoku and Genesis Drivers, and is studying the expansion of Helheim Forest with great interest. Although he is technically the subordinate of Takatora, he speaks to his boss with a overly-familiar tone and is not afraid to undermine him for the sake of his experiments.
He later becomes a user of the next-generation Genesis Driver, using the Lemon Energy Lock Seed to transform into New Generation Rider Duke.
- 0% Approval Rating: After he returns in #38 everyone hates him. Even Kouta acts like he wants to throw him out a window.
- A Glass of Chianti: Seems like the professor had some red wine stashed away in his makeshift lab. He's seen seated comfortably with a glass in hand in #43.
- Admiring the Abomination
- Absent-Minded Professor: Another dark take on an otherwise comedic trope. Ryoma lives in his own nutty world of mad science, and unless reality can help him with it he completely lacks empathy.
- Ace Custom: His Rider powers definitely seem to act this way, having the strongest punches and kicks than any other rider, including the ones who use Genesis Drivers. He is also the only one whose Driver has a transformation call (which carried over to Kaito's Driver).
- Confirmed in #39 and 40, where he shows off some extra tricks he's built in: In #39, he projects holograms to distract his enemies and in #40, he can even turn himself invisible to sneak away.
- Affably Evil: Sure, he only cares about his own plans, but that doesn't stop him from being one of the most polite characters in the show.
- Faux Affably Evil: #20 reveals his views are exactly the same as Kaito and he wants Helheim to invade. He maintains his politeness, but that revealed him as a complete villain.
- Almighty Janitor: On the surface he's just a quirky Mad Scientist but in reality he's a crazy Social Darwinist that leads his own faction that controls all of Yggdrasill's Kamen Riders.
- Always Second Best: Ryoma secretly hates Helheim because its better at making things evolve than him.
- Ambiguous Disorder: His social skills are similar to someone with high-functioning autism.
- Ambition Is Evil: Heavily gives off this vibe. As long as he can create new Drivers, he seems entirely unconcerned about the citizens suffering under the expansion of the Helheim Forest.
- Artistic License - Biology: Ryoma putting his brain into Hakaider's body violates so many biological laws it's not even funny, and raises way too many questions (like why his body didn't decompose).
- Mythology Gag: of course, those who are familiar with the Kikaider franchise know that this is perfectly reasonable within that series.
- Asshole Victim: In #43, thanks to Kaito. Honestly, are you gonna miss him at all?
- Awesome McCoolname: His surname translates to something like "Extreme War" and is a homonym for the era of the samurai.
- Awesome by Analysis: His Rider suit visor allows him to scan and process data in a moment's notice, allowing him to figure out how much of his power he has to use to beat his foes while learning about them at the same time.
- Badass: He can single-handedly wipe the floor with an Overlord.
- Berserk Button: Not knowing something. Seeing Kachidoki Arms made him flip out.
- Later on, it's revealed that his button is seeing humanity evolve without his research or study, which Kachidoki Arms and Lord Baron show.
- Be Careful What You Wish For: Ryoma also wanted to go Transhuman. Hakaider allowed him to do that...and he didn't exactly know what he was getting into.
- Bigger Bad: Of Yggdrasil, since he's the one who knew about Helheim first.
- Big Bad: By #25 it's pretty obvious who's really in charge of Yggdrasill.
- Blood Knight: When he finally gets into a straight fight, you can tell he's having the time of his life.
- Broken Pedestal: Becomes this to Minato after he goes Dirty Coward and leaves everyone to die.
- Bunny-Ears Lawyer: The guy has his quirks. When asked why the Sengoku Drivers make catchphrases, he admits it's a guilty pleasure.
- Chewing the Scenery
- Chronic Backstabbing Disorder: Minato even says he'll betray anyone for power.
- Combat Sadomasochist: He's laughing like a schoolboy when he finally gets hurt in combat.
- Crazy-Prepared: He built a secret entrance into Yggdrasill tower that only he knows about just in case something happened.
- In #43, he has a personal remote control which allows him to short circuit the other Genesis Drivers and make them useless.
- Curb-Stomp Battle: Delivers one to both Kouta and Kaito in #19.
- And Kaito returns the favor in #43.
- Cyborg: Temporarily, when he transplants his brain into Hakaider.
- Deal with the Devil: Gives one to Mitsuzane in #42: In exchange for buying Ryoma time to extract the Fruit of Knowledge from Mai, Mitsuzane would take the Yomotsuheguri Lockseed in order to defeat or possibly kill Kouta. Mitsuzane accepts.
- Didn't Think This Through: Yes, Ryoma, put your brain into a Killer Robot For Science! without checking the risks like you've always done before. Nothing could possibly go wrong.
- Dirty Coward: Even worse than Micchy.
- Disney Villain Death
- Does Not Know His Own Strength: Blames this as a result of his own inexperience in combat.
- Dragon-in-Chief: He is the one that all of the Yggdrasill Riders bow down to while using Takatora as a figurehead.
- Dragon with an Agenda: Wants Kouta's and Kaito's help in creating a new Driver that exceeds even the Genesis Drivers in power.
- Not his only agenda, either. He also WANTS for the Helheim Forest to invade the Earth, knowing that it would cause the deaths of thousands and not giving a damn.
- Drunk with Power: Gives a speech that implies he was this long before becoming Duke.
- Dull Surprise: Unless Mad Science or a Cosmic Horror Story is going on, Ryoma does a very bad job at pretending to care.
- Egopolis: Named the Sengoku Drivers after himself. But with a name like his, who could blame him?
- Evil Counterpart: To Baron. Both are based on European knights and named after aristocratic titles; and both are obsessed with pursuing something to the exclusion of everything else.
- To Ryugen as well, both are former Psycho Sidekicks with Undying Loyalty to another more powerful and charismatic Rider who turn against them when they're told something they didn't like.
- Even Evil Has Standards: After almost being consumed by Hakaider's killer programing he wonders who'd be monstrous enough to run an organization like DARK.
- Evil Genius: Yggdrasill's most important one. He invented the Sengoku Drivers, as well as the Genesis Drivers.
- Evil Is Hammy: After Ryoma becomes a more active villain his Dull Surprise is replaced with ridiculous amounts of ham.
- Evil Laugh: In #25 he tries to keep himself from doing this when Sagara confirms that Helheim contains a "forbidden fruit" that grants great power.
- Evil Is Petty: Ryoma's whole motivation is that he can't handle that Helheim might be able to make humanity evolve better than he can.
- Expy: A younger and more dangerous Doctor Maki. There would be no Creepy Doll holding him back, that's for sure.
- False Friend: He sees Takatora as a tool and nothing more.
- Evil Former Friend: Flashbacks from #27 show that Ryoma had once thought of Takatora as a man that could become the king of a post-Helheim infested world, showing genuine concern over Takatora getting injured and even designed the first Sengoku Driver as a sort of regalia for him. Of course, Takatora preferring The Needs of the Many over his own concerns, just wants Ryoma to just produce as many general Drivers as possible, which leads to a Glasses Pull event that marked the beginning of Ryoma's condescending tone towards Takatora and general decision to leave him Locked Out of the Loop.
- First Name Basis: Addresses Takatora without any honorifics whatsoever, implying a certain level of closeness to the guy. Shown in #27 to have been a former friend to Takatora.
- For Science!: Seems to have this as a motivation. Even with both the Sengoku Driver and Genesis Driver performing well, he's already seeking to design a new belt that further taps into Helheim's power.
- He serves as the antagonist for the Kikaider crossover after removing his brain and putting it into Hakaider.
- Four Eyes, Zero Soul: During #27's flashbacks.
- A God Am I: His ultimate motive. He either wants to become a god or create one.
- Hidden Agenda Villain: Ryoma doesn't care about Project Ark and is only going along with it so he can take the resources for whatever it is he's really planning.
- Invisibility Cloak: Built one into his Rider form.
- It's All About Me: As a narcissistic sociopath Ryoma is incapable of caring about anyone but himself or those he deems extensions of himself (Like Takatora used to be).
- It Amused Me: The real reason for all those Sengoku Driver voices.
- Jerkass: Though he may at first endear himself to the viewer through his quirks, Ryoma is without a doubt one of the most evil and cruel characters in the show.
- Kick the Son of a Bitch: A villainous example. He kicks Micchy's ass after revealing his Xanatos Gambit.
- Moments later gets his own at the hands of a powered up Kaito.
- Killed Off for Real: Thanks to Kaito in #43.
- Lack of Empathy: Notice that whenever science isn't concerned Ryoma doesn't seem to emote properly, with his voice rather dull, and his facial expressions forced. And him apologizing about Ryoji's death was incredibly half-hearted. Outside of science, Ryoma just doesn't care.
- Large Ham: The fact that he put voices in the Sengoku Driver purely for fun is quite silly. And as a New Generation Rider, his Genesis Driver is the only one (again, discounting Kaito, whose Driver is a copy of his) that has a transformation call. He is also the only one of the group who has his own transformation pose. Adding all of these up, Ryoma almost seems like a real-life Kamen Rider fanboy.
- Let Us Never Speak of This Again: His reaction to the Kikaider crossover.
- Like a God to Me: He used to view Takatora as some kind of God Emperor of Mankind before being jilted.
- Mad Scientist: His A God Am I Motive Rant in #15 establishes that "sanity" isn't something that Yggdrasill wants on your resume.
- Manipulative Bastard: He navigates Yggdrasill's internal politics effortlessly and in every scene he appears in he's either lying to or tempting the person he's talking to. He'd make a good politician.
- Me's a Crowd: A holographic crowd, to be exact.
- Mighty Glacier: Very powerful, but notably slower than the other New Generation Riders.
- Milking the Giant Cow
- Morally Ambiguous Doctorate: Yggdrasill sure didn't hire him with ethical concerns involved.
- Motor Mouth: He could practically go a mile a minute in his speeches if he wills it, as seen in #39 when he speaks with Kouta.
- Named After Somebody Famous: Japanese historical figure Sakamoto Ryoma.
- No Social Skills: Of the slimy Jerkass variety.
- An Offer You Can't Refuse: He knows a secret way into Yggdrasill and holds the information over the heroes' heads.
- OOC Is Serious Business: He is in shock when he witnesses Kouta's transformation into Kachidoki Arms as he does not recognize the Kachidoki Lockseed as one of his own, which is a stark deviation from his apathy or curious interest we are familiar with.
- in #42 when disscussing how to deal with Kouta, he drops his smug flamboyance darkly admitting that Kouta is an "anomaly" that he can't defeat.
- Peek-a-Bangs: He has some long bangs on the side, which sometimes hang over his face.
- Pride: Ryoma believes that only he can make something that truly surpasses humanity.
- Psycho Sidekick: Flashbacks show that Ryoma used to be Takatora's friend before turning against him.
- Psychopathic Manchild: Type C. Ryoma is a skilled fighter, leader, scientist, and schemer, but all of his actions are very childish. He treats his Kamen Rider powers like they're a toy, implanted his brain into Hakaider for fun, his off-work clothes resemble a gradeschoolers, and many people note that he treats that the battle for the Forbidden Fruit like a game.
- Sadist: Kicks Micchy's ass while torturing him, and then letting out an Evil Laugh.
- Sarcastic Clapping: To herald his return in #38.
- Skunk Stripe: Has a whitish streak in his hair.
- Slipknot Ponytail: His hair comes undone while getting beaten down by Lord Baron.
- Social Darwinist: He and Kaito have much more in common than just their Rider motifs.
- The Sociopath: He really does not care about anyone at all, and never hesitates or regrets his crimes.
- So Long, Suckers!: Seen leaving Yggdrasil Tower in an escape rocket just as it gets overgrown by Helheim in #32.
- Sure, Let's Go with That: In #17, Micchy makes up an excuse as to why he didn't betray Kouta, claiming that Ryoma didn't want Kouta to lose his belt yet. Whether or not he's right, his quick thinking impresses Ryoma enough that he's willing to back up Micchy's claim when Takatora comes calling.
- The Starscream: He frequently schemes behind Takatora's back and ultimately leads a coup against him.
- Strong, but Unskilled: At least according to him, he doesn't fully get how to completely rein in the power of his armor yet.
- This Cannot Be!: In #43 he loses his shit when Lord Baron proves himself superior to the Genesis Driver.
- This Is Unforgivable: A rather twisted and myopic variant. In his last moments Ryoma calls Kaito an unforgivable monster for abandoning his Driver and becoming an Overlord.
- Took a Level in Jerkass: After ditching Yggdrasill, Ryoma doesn't need to pretend to be a good guy to Takatora anymore, so he then frequently indulges in far more villainous behavior.
- Tranquil Fury: After regaining his composure after seeing Kachidoki Arms in action he enters this state.
- Transhuman: His other ultimate goal.
- Underestimating Badassery: He thinks that the Beat Riders are just going to roll over and die after the public turns against them, boy is he wrong.
- Villainous Breakdown: In #23 seeing Kachidoki arms and realizing that he doesn't know something he temporarily flips his shit.
- And in #43, he completely loses it, after Mai's spirit emerges from the Forbidden Fruit and takes her leave. Then he's driven to suicide by Lord Baron making him realize that Helheim is superior to him.
- Villain Takes an Interest: He thinks that either Kaito or Kouta could become the next Big Thing.
- Visionary Villain: He wants to transcend humanity.
- We Can Rule Together: He offers both Kouta and Kaito a chance to become a part of his god scheme. Both turn him down, knowing that he's nuts.
- He gives another offer to Kaito in #20. It works this time.
- We Have Reserves
- Weapon of Choice:
- With My Hands Tied: Subverted. He simply utilizes only one arm when battling Kouta in #19.
- Would Be Rude to Say "Genocide": All but says that Yggdrasill is planning on killing six billion people.
- Xanatos Gambit: Made one in #42 and profited in #43: Mitsuzane takes the Yomotsuheguri Lockseed and fights Kouta; Ryoma has time to get the Fruit of Knowledge out of Mai and therefore gains the power to become a god. He's not concerned about Mai's being, so she can die if it was necessary to get the Fruit, and if either Kouta or Mitsuzane came to stop him, Ryoma would already have the Fruit of Knowledge by then and could crush them into the dirt. Too bad the Fruit had assimilated Mai's mind by then and disappears to try and change fate.
- You Have Outlived Your Usefulness: After getting Kaito to join his side, he gives Sid the okay to kill Kouta, having no more use for him.
- Spoken to give Takatora a momentary respite, but does not follow through until #28.
Sid/Kamen Rider Sigurd
Sid/New Generation Rider Sigurd
Portrayed by: Kazuki Namioka (live), Tatsuya Kaneko (suit)
An agent of Yggdrasill who masqueraded as a self-employed "Lock Dealer" and sold Lock Seeds to the kids of Zawame City. His true purpose was to observe the effects of the experimental Sengoku Drivers on their users and ensure that things did not get out of hand. While a subordinate to Takatora, he is a slimy career-chaser who will gladly make back-alley deals if it secures him more power and influence in Yggdrasill.
He later receives one of the next-generation Genesis Drivers, using the Cherry Energy Lock Seed to transform into New Generation Rider Sigurd.
- The Aggressive Drug Dealer: "Aggressive" isn't quite the right word for Sid, but he looks and acts like a drug dealer and has sacrificed profit in the name of escalating the Invase Game more than once.
- Anti-Role Model: What he essentially is. He goes on and on about how being an adult is all about making tough decisions, but as Kouta points out, about 90% of what he says is just an excuse to be a dick.
- Arch-Enemy: The only person Kouta openly hates and shows no regret about hurting.
- Asshole Victim: While Roshuo's method of killing him was absolutely brutal, there's little doubt a monster like Sid had it coming.
- Badass: Yes, he's a smug slime ball, but he can back it up.
- Big Bad Wannabe: While he is a dangerous, manipulative threat and the New Gen Rider most actively trying to kill the heroes with or without orders, he doesn't measure up to Ryoma and Takatora. He makes an effort to break off and grab the Forbidden Fruit for himself, even teaming up with Micchy, but ultimately doesn't last two-to-three episodes before being killed off by Roshuo.
- Big Eater: Subtle, but he's always snacking on something. The only times he isn't is when he's meeting with Takatora.
- Beard of Evil
- Beneath the Mask: While he's a bit of a jerk, he seemed fairly harmless and while the Beat Riders didn't like him very much, he still seemed willing to help them...but when he's enraged, he tends to fly into a psychotic rage and openly enjoys the heinous actions he commits.
- Berserk Button: Kouta makes him angry in a way no one else can.
- Break Them by Talking: After becoming Sigurd, almost all of his dialogue with Kouta revolves around trying to verbally crush him on a moral and ideological level.
- Bunny-Ears Lawyer: Evil version. All of the Beat Riders hate him, but he's just too good at getting good Lock Seeds to just ignore.
- Captain Ersatz: It's the Badger!
- Character Tics: Holding and messing around with his S Lock Seed.
- Before and after transforming, he tips his fedora, and in battle, he has the tendency to hold onto his head like his hat is there.
- Chekhov's Gun: Remember that S Lockseed he always carries around? He can use it to control the Suika Arms armor.
- Child Hater: He even admits to hating children.
- Chronic Backstabbing Disorder: Backstabs Takatora and Ryoma in the same episode.
- The Chooser of The One: Picked out which Beat Riders were to get Sengoku Drivers, generally looking for ones who would escalate the conflict.
- Combat Pragmatist: Best shown when he shot the Banana Lockseed out of Kaito's hands before he could transform.
- The Corrupter: He takes great joy in bringing out Mitsuzane's dark side.
- Cruel and Unusual Death: Roshuo uses telekinesis to trap and crush him between two cliff faces. Perhaps one of the most violent deaths ever seen in the Kamen Rider Series.
- Dangerously Genre Savvy: The way he choose the Riders was ridiculously genre savvy. He made sure every person he gave powers to was either desperate, weak-willed, or just plain evil which would make them easily manipulable, disposable, or able to be converted to his side if they showed potential. Now if only Kouta hadn't gotten Yuya's Sengoku Driver.
- After Takatora was dealt with, Sid decided that as a Rider, he was just as qualified to pluck the forbidden fruit as any other Rider was. And so, in order to get a head start over the Yggdrasil Riders (Ryoma in particular), he destroyed the tech that kept the crack on the Takatsukasa shrine tree open so that they could no longer have a free pass into Helheim and destroyed all of their LockVehicles so that nobody else could track him down or go into Helheim as they pleased (save for the Riders that had LockVehicles prior to Sid's systematic destruction).
- Dark Is Evil
- Defeat By Irony: Non-Lethal example. While Sid captured Kouta with the Kurokage troopers, it's the DJ's "carelessly leaving behind" his keycard that allows Kouta to escape. Recall how early on, Sid himself "carelessly left behind" a Sengoku Driver for Mitsuzane.
- The Dragon: Among Yggdrasill's Riders, he takes the role of enforcer.
- Defiant to the End: Despite Roshuo's Telekinesis staggering him to the point where he can barely even move, atomizing his Lockseed and Driver, and blowing off his hat, he still refuses to back down.
- Easily Forgiven: After Takatora finds out Sid gave his little brother a Sengoku Driver, his initial reaction is to grab him by the collar in a moment of barely suppressed rage. While Sid brings up a good point in his defense, Takatora's line of "I expect you to follow through this time" comes off as nothing but na´ve. He also goes unpunished for trying to use lethal force against Gaim and Baron, despite Takatora's insistence on protecting them.
- Enigmatic Empowering Entity: Distributes the Sengoku Drivers and bikes to the various Beat Rider teams, often even for free. The Riders didn't know that it was for the purpose of giving Yggdrasill new lab rats.
- Enigmatic Minion: While he's working for Yggdrasill, he kept the fact that he gave Mitsuzane a Driver a secret from his brother for an unknown reason. More than that, he gave Takatora every opportunity to find out, but was amused that he hadn't taken the bait.
- Evil Counterpart: To Bravo (well, Evil-er Counterpart). Unlike the other Armored/New Generation Rider comparisons, they don't share an armor theme, but they both enjoy antagonizing others and especially picking on children. However, Sid ultimately turns out to be completely irredeemable, while Oren starts working with the heroes once he's appraised of the whole situation.
- Evil Laugh
- Evil Wears Black: Bonus points for being the most evil person on the show.
- Expy: Has Gilgamesh's hero motif as Sigurd. He was also the one who pushed Micchy onto a dark path, just like how Gilgamesh convinced Kirei to follow his evil instinct. He also shares Gilgamesh's contempt towards human society.
- Famous Last Words: I...I...I will become more than human!
- For the Evulz: Seems to be the reason he likes screwing with people's heads and seemed to actually get a kick out of killing Hase and then smugly rubbing it in Kouta's face.
- Freudian Excuse: Implied. Part of his motive for getting the Fruit for Knowledge was so that no one would look down on him again. There was also his attitude towards Kouta and Kaito about how adults are the responsible ones.
- Friend in the Black Market: To anyone willing to pay for his services in the first arc. He closes up shop afterwards, partly because Kouta called him out on just using the Beat Riders as lab rats and partly because Yggdrasill was ending that project anyway.
- Gory Discretion Shot: When Roshuo crushes him the camera tilts upward swiftly to spare the viewer from seeing his gruesome demise.
- Hate Sink: Sid is such a slimy, smug, soulless, scumbag that All-Loving Hero Kouta openly hates him, telling the audience to direct their hate onto Sid.
- Hero Killer: Kills off Hase during his first bout as Sigurd.
- Homing Projectile: His arrows can do this.
- Hope Crusher: Sid has made it his personal goal to crush Kouta's ideals.
- Hope Is Scary: He tells Kouta he opposes him because he's giving people false hope that will only be crushed. Given it's Sid, however, it's not clear how much he believes it and how much is just an excuse to mess with Kouta's head.
- Every attempt Sid has made to crush Kouta's resolve has somehow strengthened it.
- Sid originally let Kouta live because it was fun to make him squirm while Takatora wanted to take more decisive action. Nowadays Sid is the biggest advocate for killing Kouta while Takatora lets him go out of sympathy.
- The rider responsible for the first Rider death ends up being the next Rider to die.
- Originally, Sid distributes the Sengoku Drivers to Beat Rider teams because of how easily manipulable and accepting they are of power given to them for free, and he believes that 'adults' like Sid would question this. This comes to bite him in the ass in #31, as he was easily tempted by the forbidden fruit offered by Redyue, getting him killed. Micchy knows that it is a trap and decides not to follow him.
- Sid comments that Micchy watching his brother supposedly die without trying to stop his killers was rather cold of him. It's that same coldness that has Micchy not inform Sid of the trap and just have him march to his death. To add further irony, his brother gets to watch Sid die without trying to stop his killer.
- It's Personal: For some reason, he hates Kouta on a personal level, dropping his Slime Ball persona when fighting him in favor for a more bitter, jaded outlook on life while trying to break him.
- Jack of All Stats: The most balanced of the New Generation Riders.
- Jerkass: To the point where All-Loving Hero Kouta hates him.
- Kids Versus Adults: He often tends to talk about how adults are the master authority towards kids and how they should respect their elders. Both Kouta and Kaito respond by telling him where he can shove his agism.
- Knight of Cerebus: Responsible for the show's first Rider death, which the lead writer calls the turning point of the story and says the one line that confirms that this is a deconstruction of Kamen Rider.
- Laser-Guided Karma: The murderer of the first Rider fatality is the second Rider fatality
- Meaningful Name: Twofold: The first being his name being a sound-a-like to seed, as in Lockseed. Then there's his Rider name. Sigurd relates to a heroic monster hunter. Hence his speeches regarding hunting down monsters being heroic.
- Manipulative Bastard: He just loves to find out your hopes and dreams, then twists and corrupts them for his own amusement.
- Nice Hat: A black bowler. It's ultimately used for a Dead Hat Shot.
- Nice Job Fixing It, Villain:
- As noted above in Irony, every attempt Sid has made to crush Kouta's Heroic Resolve just makes him bounce back stronger than before.
- Inverted in #21. Him telling Kouta about the Scalar Weapon actually had Kouta team up with Yggdrasil to prevent Inves from coming out of a public crack. But played straight again in #23 as Kouta learns to go for the Scalar system while Storming the Castle and trashes it completely.
- Not-So-Harmless Villain: While Sid was never harmless, all he seemed like was your typical corporate slime ball who would fold after the Riders got tired of his BS...But then he's revealed to be New Generation Rider Sigurd, who proves this assumption to be very wrong when he kills Ryoji.
- Obviously Evil
- Only in It for the Money: Claims that money is his only motivation. This is a very obvious lie.
- Pintsized Powerhouse: He's rather short, but very tough.
- Punny Name: Sid <-> Seed. Also Sigurd.
- Psycho for Hire: Unlike the other Yggdrasil employees, who either view their actions as a Necessary Evil or a means to an end, he enjoys his heinous actions, including killing Hase and trying to kill Kouta. While he talks a heroic talk, it seems to be only an excuse to perform heinous acts because he wants to.
- Red Eyes, Take Warning: As Sigurd.
- Red Is Heroic: Well, he insists he's heroic, but he's far from it.
- Shoot the Dog: He describes his execution of Hase as this, though primarily as a way to mock Kouta - he doesn't seem to be the type who's concerned about "morality".
- Silly Rabbit, Idealism Is for Kids!: He constantly taunts Kouta that his ideals are immature and childish.
- Slime Ball: The man oozes corporate slime.
- Smug Smiler
- The Sociopath: Is charismatic enough to have easily convinced the Beat Riders to take his wares, takes a sadistic pleasure in screwing with people's heads, and has zero empathy for anyone else. He also escalates the Invase Game seemingly on a whim without orders from his superiors more than once. He also shows a violent, homicidal streak when he's actually enraged, to the point of outright trying to kill Baron and Gaim in anger when they get the slip on him. He also seemed to enjoy killing Hase as opposed to his comrades, who either viewed it as a Necessary Evil or were indifferent.
- Soft-Spoken Sadist: While he has charisma and speaks calmly most of the time, the guy is notably the only Yggdrasil member to outright enjoy his heinous actions instead of seeing them as a Necessary Evil or a means to an end.
- Spell My Name with an S: The TV-Nihon fansub initially Romanized his name as "Cid" before switching to the more accepted "Sid."
- The Starscream: He not only helps Ryoma undermine Takatora, once that's out of the way he backstabs Ryoma too.
- Suicidal Overconfidence: He dips into this trope from time to time, such as thinking that he has what it takes to kill Takatora or defeat Roshuo.
- There Is No Kill Like Overkill: His solution to deal with Kachidoki Arms is three Watermelon Arms. It doesn't work.
- Unskilled, but Strong: Sid's fight with Kouta in Episode #21 shows that he's not that skilled of a fighter when he doesn't have the sheer power of being a New Generation Rider to rely on. When he faces a foe of equal power but superior fighting skill, like Kouta in his Jinba Arms or Kaito after getting a Genesis Driver of his own, Sid's shown to be badly outmatched. He seems unable to accept this fact, ultimately leading to him being completely slaughtered at the hands of Roshuo, and his death.
- Villain Has a Point: In the end, he appears to be right about killing Ryoji being the only option, and that if he was allowed to run free he could have hurt a lot more innocent people. Kouta admits that he may have a point, but argues that using justice as a rationalization for killing is wrong.
- Villainous Breakdown: A very minor one after Kouta and Kaito give him the slip in episode 15.
- A much bigger one after Kouta beats him and steals his Lockseed in episode 21. Given how Sid was completely confident that he'd kill Kouta, the shock on his face after Kouta managed to decisively beat him is priceless.
- Weapon of Choice:
- Would Hurt a Child: Despite viewing the Beat Riders as kids, and them being much younger than him, he has no problem beating the tar out of them and trying to outright kill them.
- You Got Spunk: A rather dark take on this trope. The reason why he gave Mitsuzane his Sengoku Driver was because he was impressed by his dark side. He also gave out the last three Drivers to teams willing to break away from Baron's alliance.
- You're Insane!: Kouta calls him this after he reveals Yggdrasill's backup plan to nuke the city if the situation goes completely FUBAR.
Yoko Minato/Kamen Rider Marika
Yoko Minato/New Generation Rider Marikanote
Portrayed by: Minami Tsukui (live & suit), Satoshi Fujita (suit understudy)
An employee of Yggdrasill Corporation working under Ryoma Sengoku. She acts as his personal bodyguard and assistant in the company using her incredible martial arts.
Using the Peach Energy Lock Seed and the Genesis Driver, she can transform into New Generation Rider Marika.
Portrayed by: Tomomitsu Yamaguchi
The host of "Beat Riders Hotline", an internet radio station with its finger on the pulse of Zawame City's urban scene. He reports on the activities of the Beat Riders street gangs and runs popularity polls to determine who the top dog is. He is actually an agent of Yggdrasill Corporation who uses his web channel to distribute propaganda and galvanize the conflict between the Beat Riders. But there's more to him then even that, as his motivations and other things about him have been called into question; all we know for sure is that he put himself in a position to observe the Helheim conflict. Near the end of the series he's shown to be the avatar of Helheim itself. For Helheim Forest specific tropes, see here
Portrayed by: Yuki Anai (voice), various suit actors
The private security force of Yggdrasill Corporation, who use a mass-produced version of the Sengoku Driver to transform into copies of Armored Rider Kurokage.
- Cool Bike: The Dandeliners. Unlike the Beat Riders' cycles, these are hover bikes.
- Conservation of Ninjutsu: One Kurokage was a decent opponent; now they fight in groups and are cannon fodder.
- Degraded Boss: When Ryoji was the only Kurokage, he was originally presented as roughly equal to the other Armored Riders (despite having lower stats). Now it's a Mook powerset.
- Red Shirt Army: Sort of; throughout the series, they're aren't shown to be that good at their job.
- Ninja: A cross between this and Japanese footsoldiers; though they act more ninja-like than Ryoji did. The Troopers are very good at magically appearing and disappearing like the warrior that they were based on.
- Screw This, I'm Outta Here!: After Ryoma abandons them against Demeeshu all of the troopers desert Yggdrasill en masse and flee the city along with the civilians.
- Villain Teleportation
- Weapon of Choice:
- Blade on a Stick: The Kagematsu in Pinecone Arms.
- Kill It with Fire: They are each sometimes equipped with flamethrowers, specifically to burn down all plants grown by Inves.
