Dr. Pac-Man/Michihiko Zaizen
Portrayed by Shiro Sano
Yes, seriously. The yellow gobbler appears as a villain in Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legendary Riders. His true identity is a Mad Scientist named Michihiko Zaizen.
- Adaptational Villainy: The usually happy-go-lucky Pac-Man will try to devour the human race. Though to be fair, it's not his first stint as an antagonist. Turns out, this guy is just a Mad Scientist taking Pac-Man's identity and who wants to infect the human race with Pac-Man viruses and rule the world.
- Back from the Dead: He and the other scientists of the Next Genome Institute were mysteriously killed in a Freak Lab Accident according to the CC footage in Shinnosuke's police report. They return as data entities after their supposed deaths.
- Dr. Pac-Man's monster form, Genomes, returns in Kamen Rider Para-DX with Poppy when Zaizen's daughter summons him.
- Big Bad: He's the leader of the Next Genome Institute and is the main antagonist of the crossover movie with Kamen Rider Ghost.
- Create Your Own Hero: His tampering with Emu as a young man is the reason he was able to use the Gamer Driver and become Ex-Aid.
- Death by Irony: He tries to inflict this on Emu by activating a Proto Mighty Action X Gashat into his Gamer Driver along with his normal Mighty Action X Gashat to banish him to the digital world like he was 6 years ago.
- Freak Lab Accident: When the Daitenkū Temple's paranormal investigations office approaches Detective Tomari for the police's help in learning about the Next Genome Institute, they review CC footage of the scientists' supposed deaths in one of these. As it turns out, they were performing surgery to manually extract the original Bugster virus from a young Emu Hōjō, and the wave of data it released seemingly killed them, but they were reborn as data beings.
- Greater-Scope Villain: Believe it or not, the crossover villain actually counts as this to the plot of Ex-Aid. He reveals that the Next Genome Institute was behind the creation of game disease and had a crucial role in the emergence of the Bugster virus, namely in surgically extracting Parado from Emu's body, bringing about the original Bugster virus that all other strains of game disease descend from.
- He's also the father of Saiko Yaotome, and her pursuit of revenge for him against the heroes drives her actions in Another Ending.
- Hoist by His Own Petard: His attempt to inflict an Ironic Death on Emu instead results in the first iteration of Mighty Brothers XX, which Emu uses to destroy him.
- LEGO Genetics: His plan is to create the Hatena Bugster, spawned from a new strain of game disease based on an independently developed puzzle game, and use Hatena's DNA altering powers as a gene therapy treatment to make humanity completely immune to all disease and damage (as well as give himself a monster form, Genomes).
- Logical Weakness: In the original Pac-Man game, Pac-Man's natural enemies are ghosts, hence the Pac-Man virus's main weakness are ghosts. How fitting that the movie he shows up in is primarily a team-up with Kamen Rider Ghost.
- Mad Scientist: He leads a whole group of them. His daughter takes after him in this regard.
- Nice Job Fixing It, Villain!: His harvesting Emu of the Bugster Virus when he was a young man is what gave him his natural immunity that's even stronger than the surgery the immunization surgery causes. So not only does this mean he's the reason Emu was able to become Ex-Aid in the first place, he's also the reason Emu was able to use the blank Gashat Parado gave him and obtain his Level X and Level XX forms, which would have killed even those who have gotten the immunization surgery.
- One-Winged Angel: Michihiko Zaizen's final form is Genomes, achieved by having the Hatena Bugster rewrite his DNA.
- Outside-Context Problem: Yeah, yeah, he's a video game character in the gamer rider series, but seriously, did you ever see this coming?
- This is actually downplayed as there are only a few out-of-context aspects to him. One is that the video game hes from exists in real life rather than being a game made up for the series, and the other is the fact that hes a human assuming an identity based off of a video game character, unlike the Bugsters who are video game characters brought to life. Dr. Pac-Man is otherwise an aversion, since his actions play a pivotal role in the backstory of Ex-Aid.
- Well-Intentioned Extremist: He insists he's one of these as his research all goes into the benefit of helping mankind attain the status of Ultimate Lifeform, beings that would be completely immune to harm or disease. Unfortunately, only 1 in 100,000 (at least) people is compatible with the process and his way of sussing out those exceptional individuals is to infect large swaths of the population with Game Disease.
Portrayed by Takashi HaginoHe's Back. The murderous snake rider of Kamen Rider Ryuki appears in the Kamen Rider Brave special to play a new game he's heard about and to have some fun as usual. For tropes applying to him in his home series, see here.
- Adaptational Wimp: Played with since he's more brutal as a human than he was in his series and his Rider form actually wins a fight against Hiiro as Brave Level 2. However, Asakura is shown not fighting at his full potential and gets defeated when Brave uses his new Gashat to enter Level 4.
- Ax-Crazy: Asakura hasn't changed a bit, and is willing to murder whatever comes into his line of sight.
- Bloodier and Gorier: When he shows up, there's a lot more Family-Unfriendly Violence in the special, such as Emu being shoved into a bucket of glass.
- Blood Knight: Enjoys fighting in general, even if he's getting rid of his own teammates in the process.
- Bullying a Dragon: He's introduced wielding a pipe and trying to fight the Beast Riders. Considering the fight that the average Kamen Rider can punch and kick with tons of force, move at amazing speed, and withstand lots of damage, Asakura should consider himself lucky that the Riders had no personality to defend themselves from him.
- Chronic Backstabbing Disorder: His teammates mean absolutely jack to him, and if they keep him from murdering someone, he'll murder them too.
- Combat Sadomasochist: When he's about to stab the target with a shard of glass, he squeezes it extra hard to make himself bleed.
- Cool Sword: The Venosaber.
- Enemy Eats Your Lunch: When he confronts Satsuki on her way home from work he takes a raw fish from her groceries and starts to messily eat it in front of her, mostly to freak her out.
- Forgot About His Powers: Only uses Sword Vent in his fight with Hiiro. He doesn't use any of the other cards he used in his home series, which include four Final Vent cards, three Advent cards that allow him to summon three Contract Monsters, and a Unite Vent to summon his strongest Contract Monster to aid him in battle.
- No Body Left Behind: When he's defeated, he disappears much like the Ryuki Riders in the Mirror World. Being associated with Foundation X seems to imply that he's not completely normal and presumably this Asakura is not the same Asakura that Kanzaki revived in his timeline reset at Ryuki's finale.
- Pipe Pain: Uses a pipe as his main form of attack while in human form. He uses it against the Beast Riders and to brutally assault Satsuki and Emu to the point of critical injury.
- Reptiles Are Abhorrent: Has a snake-themed powerset and still an utter monster to the core.
- Villain Team-Up: While it is obvious that he's part of Beast Rider Squad and all of them are villains (well, except Kamen Rider Beast), he had a special case since he had to work together with an energy construct of one of his arch-enemies, Satoru Tojo/Kamen Rider Tiger. That did not stop him from attacking him mercilessly. Or anyone in the Squad really.
- Would Hit a Girl: He savagely beats one of Hiiro's assistance nurses with a pipe and nearly stabs the other with a glass shard before Hiiro intervenes.
Kamen Rider True Brave/"Another Hiiro"
Portrayed by Toshiki Seto
A Mirror Self of Hiiro Kagami who emerges from the Game World. He uses the Taddle Legacy Gashat to transform into Kamen Rider True Brave (Lv.50). He is a subconscious embodiment of Hiiro's ideal of himself as a "perfect doctor" who makes no mistakes, and of Hiiro's refusal to accept the inhumanity of such a standard.
- The Dragon: To Eito who is the one behind the link between the real and game worlds.
- Early-Bird Cameo: Not him, his primary Gashat, Taddle Legacy, which would later be revealed to be Brave's Super Mode.
- Evil Twin: A mirror self of Hiiro from the Game World, though played with, since besides challenging Brave to a fight, he does very little villainy as he's only helping Eito escape reality to not face his past. After being defeated, he wants Hiiro to save Eito from making a big mistake.
- Expy: Of Makoto Doppelganger since both of them are being an Evil Twin of the secondary riders of their respective series.
- Graceful Loser: Upon being defeated by his real world counterpart Brave, he would accept his defeat and give Brave the Galaxian Gashat as a prize.
- Light Is Not Good: His armor is a white version of Brave Fantasy Gamer LV 50. He's also a villainous rider. Turns out he's not that villainous after all as his form stems from not being able to save Eito. He is more than willing to give his opponents rare prizes if he is beaten in honorary combat.
- Noble Demon: He wants nothing more than a fair fight with any of his opponents.
- Original Generation: Much like Fifteen and Rider #3 before him.
- Our Gryphons Are Different: The lion motif and angelic wings adorning his armor give him this look. It gives him a magestic look in contrast with Taddle Fantasy's demonic and sinister appearance.
Portrayed by Riku Onishi
A genius programmer and a former patient of Hiiro Kagami. He is the creator of the Chou Super Hero Taisen game, and resides in the Game World of said game for the most part.
- Child Prodigy: He's a young programmer who is able to create a game out of both long time Super Hero franchises.
- The Dog Was the Mastermind: He's behind the Chou Shocker Taisen bonus stage that was made to bring back villains of both franchises to destroy the real world in order for him and Another Hiiro to escape reality. Once the link he made between both worlds gets severed by Hiiro, Shocker Great Leader III takes over the Big Bad role for the final act of the movie.
- Emotionless Boy: He is said to be born without emotions making him Not So Different with Naga Ray. Deconstructed Trope when if he doesn't feel anything of the real world, he plans to destroy it to stay in the game world while Naga Ray is a Kyuranger who wants to protect reality and the people.
- HeelFace Turn: He's finally able to leave the game world thanks to Hiiro and is even showing happiness with actual heroes and the ones he made in his game.
- Lack of Empathy: To the point that he refused to take surgery that would save his life and destroying the real world because he won't feel from it.
- When He Smiles: In the ending as he sees his game and the ones he created waved at him in his handheld.
Kagenari Nagumo/Kamen Rider Fuuma
Portrayed by Yoshikuni Dochin
The Dark Rider appearing as a main villain in the Ex-Aid summer movie True Ending. A man working for Johnny Maxima, CEO of a foreign company, Machina Vision, who traps people in a VR-like "eternal heaven" world with his Ninja Gamers in order to get a cure for his daughter. Notable for being the first rider to be explicitly ninja themed.
- Blow You Away: Capable of using multiple tornado-like techniques with both his blades, fitting for his Gashat's name.
- Conservation of Ninjutsu: Ironically enough, it's actually quite downplayed; while Fuuma is shown to be far more powerful than the numerous Ninja-Players, the Ninja-Players aren't the standard mooks when it comes to combat, quickly overwhelming the Riders with sheer numbers and skill.
- Cool Mask: Kamen Rider Fuuma wears a very nice mouth guard that resembles a ninja face mask along with headgear. The Ninja-Players also have cool helmets that include monoeyes.
- Disappeared Dad: He was never around in his daughter Madoka's life. He's not very proud of himself for it.
- The Dragon: To Johnny Maxima. He attempts to usurp him and seemingly succeeds, only to be punted back down into this role when Maxima reveals he's Gamedeus.
- Dual Wielding: Kamen Rider Fuuma uses dual Ninjatous as his personal weapons in Ninja Gamer form.
- Early-Bird Cameo: Machima Vision is mentioned in Episode 39 along with Johnny Maxima as a nod towards the movie, along with a motto that eerily sounds like Gamedeus was screaming during one of the previews
- Elite Mooks: Kamen Rider Fuuma's Ninja-Players are not the standard Ride-Player. They are much more powerful, even being on par with Level 50 Riders.
- Expy: Not him, but rather, his Gashat, Hurricane Ninja. A Gashat that can turn anyone who uses it without a Gamer Driver into a Ninja Player, while using it with a Driver turns the user into a Rider, basically makes it a Gamer Driver version of Kamen Rider Chronicle.
- Finishing Move:
- Hurricane Critical Strike: Fuuma empowers and spins his dual blades before throwing his swords in a hurricane-like slash towards his enemy.
- In other media like in the arcade game Kamen Rider Battle: Ganbarizing, Kamen Rider Fuuma throws multiple shurikens in high speed at his opponent.
- Katanas Are Just Better: Fuuma's dual Ninjatous.
- Mook Maker: When Hurricane Ninja Gashat is activated, Fuuma can use the ability to summon several Ninja Players in order to swarm his enemies.
- My God, What Have I Done?: He does a good job of hiding it under a stoic facade, but his motivations are largely driven by guilt over abandoning his daughter only for her to turn out to be terminally ill.
- Ninja: He uses the Hurricane Ninja Gashat, while his appearance is based on the Fuma Ninja clan.
- Stock Ninja Weaponry: Fuuma uses dual Ninjatous and the Ninja-Players use short swords and shurikens.
- Tragic Villain: At his core, he's a grieving father trying to make it up to his terminally ill daughter for abandoning her.
- Zerg Rush: The Ninja-Players can swarm their enemies with sheer numbers.
Johnny Maxima/Gamedeus Machina
Portrayed and voiced by Brother Tom
The main villain the Ex-Aid summer movie True Ending and CEO of a foreign company, Machina Vision, who traps people in a VR-like "eternal heaven" world, using the game disease.
- A God Am I: Practically every CEO in the show is like this, but Maxima gets extra credit for his company's corporate philosophy on their website being an allcaps "I AM GOD". It's foreshadowing the fact he's really Gamedeus.
- Author Appeal: In-Universe, his obsession with Japan and with ninja in particular is the reason for the motif of Hurricane Ninja.
- Big Bad: Of The Movie, being Fuuma's boss.
- Bishōnen Line: Zig-Zagged. His first transformation into Gamedeus Machina appears as a smaller version of Super Gamedeus, but after (seemingly) destroying Kuroto and Parado it compresses into a more humanoid form that more closely resembles Gamedeus in his default monster form, even though he implies that the change made him stronger. Later, after fighting the Riders again, he grows into Super Gamedeus at the original's size.
- Dragon Ascendant: The reveal he's Gamedeus makes him this, given in the series proper Gamedeus only served as a minion for Chronus where here he's become the Big Bad.
- Early-Bird Cameo: Appears in the series prior to the movie, where Masamune attempts to strike a deal with him to assist in the international distribution of Kamen Rider Chronicle, which ultimately falls through. Maxima later observes Graphite's last stand and walks away with the dropped Gashacon Bugvisor.
- Evil Laugh: A large percentage of his dialog as Gamedeus Machina is maniacal laughter.
- Foreign Culture Fetish: Is a major Japanophile, expressing a love for the country and ninjas.
- Gone Horribly Right: He's technically fulfilling his purpose of being the most powerful and destructive final boss he can possibly be.
- Lotus-Eater Machine: His "eternal heaven" virtual reality inside the game world of Hurricane Ninja is one for Kagenari's daughter Madoka, who is too ill to enjoy outside activities in the real world. Her moments of happiness in this world create Hurricane Ninja Gashatrophies, which Maxima later absorbs to unlock the full power of Gamedeus.
- Meaningful Name: Gamedeus Machina is an obvious pun on Deus ex Machina. The term means 'God from the Machine', which given Gamedeus is a God of Evil originating from a video game, is a fairrly fitting description of him.
- Omnicidal Maniac: His true motivation once he regains his true power as Gamedeus. Justified as he's the Final Boss of a video game and that's what his programming was.
- One-Winged Angel: Turns into Gamedeus Machina. He's actually Gamedeus and his entire plan was to become complete.
- Palette Swap: His Gamedeus Machina form is a red recolor of Gamedeus. Ironically, it's implied he is Gamedeus rather than simply turning into him.
- Punny Name: His monster form, Gamedeus Machina, seems like a pun on Deus ex Machina.
- There Is No Kill Like Overkill: Tries to kill Ex-Aid Hyper Muteki by shifting into what is essentially a giant sword that drops onto him through a building. It doesn't work.
- This Cannot Be!: His last words before going boom.
- True Final Boss: Is a reference to this trope, as he's the Big Bad of True Ending which is itself a play on games having multiple endings with only one true one. Fittingly, he turns into a differently named Palette Swap of Gamedeus called Gamedeus Machina, and is implied to actually be Gamedeus trying to become whole.
Kamen Sentai Gorider
- Animal Themed Super Being: Have the original Kamen Rider's grasshopper theme to them.
- Badass Cape: Like the Gorangers, they all have capes. And given they're a fusion of a Sentai Team and a Kamen Rider, it's reasonable to assume they're badasses.
- Badass Crew: They're a Sentai Team composed of Kamen Riders, and either one of those things is badass on its own. It helps that both versions of the team are composed of experience Riders or Sentai from other series and, judging by the Gorider miniseries, stronger than Ex-Aid Level 99 by a considerable margin.
- Composite Team: The outfit brings to mind the original Kamen Rider, while the colors and names bring to mind the first Sentai series - in fact, the names of the ranger are the exact same as those of the Gorangers, with "Rider" replacing "Ranger". Interestingly enough, they'll be appearing alongside at least one member of the Gorangers.
- Legacy Character: The ability to become the Goriders is the prize for the team that wins the Ultra Superhero War tournament, with Team Ex-Aid claiming victory and becoming the first Gorider team. The Kamen Sentai Gorider miniseries features a group composed of different Kamen Riders becoming the second Gorider team.
- Ninja Pirate Zombie Robot: They're a Super Sentai team composed of Kamen Riders.
- Original Generation: An entire team of this to boot!
- Ragtag Bunch of Misfits: The miniseries starring them has the team consisting of:
- Sixth Ranger: Ex-Aid acts in this capacity to the second Gorider team, even if he isn't using a Gorider form himself.
- Wrong Genre Savvy: Most of the second team is deeply suspicious of Emu due to their past experiences with depraved individuals who hid their wicked intentions behind masks of affability and faux innocence.
Portrayed by Yutaka KobayashiThe ruthless former leader of Team Baron turned into an Overlord returns as one of the Riders that was brought back in the Gorider miniseries. For tropes applying to him in his main series, see here.
- Alliterative Name: Kaito Kumon.
- Back from the Dead: For the third time in fact. While the others are also this, Kumon is the only one to have been revived (and appeared in human form) before Gorider (temporarily revived as Mecha Kaito in Kamen Rider × Kamen Rider Drive & Gaim: Movie War Full Throttle and as Lord Baron in Kamen Rider Ghost Legendary Riders Souls).
- Heroic Sacrifice: Sacrifices himself to ensure that Kuroto will remain dead and to let Emu and Kanzaki get out of there alive.
- Knight In Sour Armor: He is still this after all of the time he spent in the afterlife.
- Mythology Gag: He already met Gaim's successors Drive and Ghost before, so why not meet Ex-Aid as well?
- Also, Kaito gets Aka-Rider as his Gorider form (i.e. the equivalent of being a Red Ranger). For those who did not know, Yutaka Kobayashi was the top contender for portraying Captain Marvelous/Gokai Red before he had to turn down the role. So now, Kobayashi gets the chance to play the role that he had to turn down.
- The Leader: He gets Aka-Rider's powers when Emu gave the Dead Riders the Gorider cards that he won from Chou Super Hero Taisen.
Portrayed by Takanori KikuchiThe former rival of the eponymous Agito and the Back-Alley Doctor of Kamen Rider Agito returns as one of the five Riders that Kuroto brought back to life in Gorider. For tropes applying to him in his main series, see here.
- Alliterative Name: Kaoru Kino, as well as Another Agito.
- Back from the Dead
- Good Old Fisticuffs: He's weaponless contrast to the other Riders and fights with his fists. It helps reinforce his "old school brawler" motif he's got going on.
- Heroic Sacrifice: Sacrifices himself to ensure that Kuroto will remain dead and to let Emu and Kanzaki get out of there alive.
- Jerkass: He's this to Emu at first, mainly because he thinks that Emu is the mastermind of the story.
- Jerk with a Heart of Gold: After he realizes Emu's not the culprit he softens. When Emu loses his memory again, Kaoru is patient with him and expresses his worries.
- Mythology Gag: He used to be a doctor, and he returns in a series where one of the main plots is Medical Drama.
- Unexpected Character: No one really expected Kino to appear in Gorider, especially since he's not seen in human form after Agito ended.
The Real Kazuma Kenzaki
Portrayed by Takayuki TsubakiThe main protagonist of Kamen Rider Blade returns as one of the five Riders that was brought back to life in Gorider.
As it turns out, the Blade that we saw early on is not the real Kenzaki. Rather, it's Kuroto Dan disguising as Kamen Rider Blade so he can trick the others so his plan could work. Unfortunately, him using Blade's powers draw the attention of the real Kenzaki, prompting him to go to CR in order to enter the game and spoil Kuroto's plan.
For tropes applying to him in his main series, see here.
- Alien Blood: Because he's an Undead, he bleeds green blood. The fake Kenzaki, however, still bleeds red blood.
- Alliterative Name: Kazuma Kenzaki.
- Apocalypse Maiden: A Joker Undead and thus could potentially become this as the world's other surviving Undead is sealed, save for the other Joker Undead. Weaponized by Kenzaki to ruin Kuroto Dan's scheme by entering his Game World...and then promptly causing doomsday to befall it because he's the only Undead present in it.
- Back from the Dead: Subverted as it turns out he's alive and well.
- Big Damn Heroes: His presence inside the Game World saved Brave and Snipe from getting killed from the endless horde of Bugsters that came for the two of them in the real world.
- Blue Is Heroic: Subverted as Kuroto!Kenzaki, played straight by the real Kenzaki.
- Foreshadowing: In episode 1, Kenzaki did not appear on the mirror despite he's still alive. This foreshadows the reveal that this particular Kenzaki is actually not the real Kazuma Kenzaki. The real Kenzaki would appear in episode 3.
- I Was Just Passing Through: Rather literally at that; the real Kenzaki got involved when he sensed the presence of Undead powers in the game and quickly derails Dan's entire plot by basically just walking up to everyone in the game and announcing his presence.
- Metaphorically True: Him not having a reflection in the mirror note is explained away by him as his human side dying after he became the Joker Undead. Subverted, as revealed in episode 3, it turns out that "Kenzaki" is dead in the conventional sense; he's Kuroto Dan.
- Sixth Ranger: After properly getting involved in Dan's game world, he decides to help out since he's already there anyways and wants to see it through to the end.
- Spanner in the Works: Becomes this to Kuroto since he's the Joker Undead. Once Kuroto drops his Blade powers, the game world starts to disintegrate before Kenzaki reveals that since he's now the sole Undead remaining (and a Joker in that), whatever world that he is on right now will be destroyed. This allows the Riders to beat Kuroto's "unbeatable game".
- The End of the World as We Know It: His presence completely annihilates Kuroto's "unbeatable" game world.
- Walking Spoiler: The fact that he's not actually Kenzaki when we first see him isn't revealed until the final episode and is connected to nearly every question about the world the Riders ask.
- What Happened to the Mouse?: Blade is not seen again once he and Emu escapes Game World. Although, it is safely assumed that he's alive, considering that he's immortal and if he was dead, the other Joker Undead remaining on Earth would trigger the apocalypse.
Portrayed by Minami TsukuiShe's back. The former Yggdrasill employee turned into Kaito's personal bodyguard is one of the Riders that was somehow brought back to life in the Gorider miniseries. For tropes applying to her in her main series, see here.
- Adaptational Heroism: After alternating between good and evil in her main series, she ultimately died as a Heel due to siding with Lord Baron. In the Gorider miniseries however, she and Kaito were portrayed as more heroic than she's normally was in the main series.
- The Heart: She's uncharacteristically the most compassionate of the five dead Riders, and is the one to convince the others to trust Emu. This is later compounded with her transformation into Momo Rider.
- Heroic Sacrifice: Sacrifices herself to ensure that Kuroto will remain dead and to let Emu and Kanzaki get out of there alive.
- Odd Name Out: The only one of the dead Riders to not have an alliterative name, and also the only one to not have a name that starts with a "K".
- Pink Heroine: Well, her Rider color is pink. And she's the only female Rider between the dead Riders. What do you expect?
- The Smurfette Principle: The only female Rider to appear in the Gorider' miniseries.
Kamen Rider Ex-Aid Trilogy: Another Ending
Doctor Saiko Yaotome MD (real name:Saiko Zaizen)
Portrayed by Yurina Yanagi
A doctor specializing in regenerative medicine. To aid in the recovery of game disease victims who disappeared, she heads a training game called Let's Make Bugsters, and conducts a test run alongside Emu involving raising Poppy and Parado. She appears in all three Kamen Rider Ex-Aid Trilogy: Another Ending epilogue specials.
- Avenging the Villain: She wants revenge on the heroes for her father, Michihiko Zaizen.
- Black and White Insanity: She hates Bugsters with passion. Her thoughts are mostly down to "humans - good" / "bugsters - bad". Her abuse of Parado and Poppy through the movie showcases this pretty well too. She realized that she is wrong by the end and didnt cope with it very well.
- Bitch in Sheep's Clothing: She is introduced as a doctor helping CR to restore the victims of Game disease, but she's actually Kuroto's ally in his master plan.
- Daddy's Little Villain: As it turns out, she's the daughter of Michihiko Zaizen and wants revenge on Parado for taking her father away, which leads to her working with Kuroto.
- Distaff Counterpart: To Kuroto. She is smart, ambitious, and a manipulative Mad Scientist, even if by far not as crazy as he is.
- The Dragon: To Kuroto.
- Force Feeding: She forces a cherry into the captured Poppy's mouth in a scene in Para-DX with Poppy.
- HeelFace Turn: She ultimately defects from Kuroto's side by the end and even helps save Kiriya's life.
- Mad Scientist: Like father like daughter.
- Mad Scientist's Beautiful Daughter: Overlapping with Daddy's Little Villain in such a way that you could even say like father like daughter.
- My God, What Have I Done?: She is horrified when she sees her plans used to Kuroto's advantage.
- No Sense of Personal Space: She has a tendency to get up close and rather touchy with her hands when she interacts with people.
- Power Nullifier: She reverse-engineers one of the proto gashats to create cords with the same Level 0 capabilities when she captures Parado and Poppy.
- Ship Tease: With Kiriya. When she demonstrates herself to have No Sense of Personal Space, Kiriya can be seen standing awkwardly around her with an expectant look on his face. She later winks at him as she leaves his hospital room after she saved his life.
- Superior Successor: A brilliant Mad Scientist like her father Dr. Pac-Man before her, she manages to conduct a complicated surgical procedure on Masamune Dan's restored body to extract Another Parado from him all on her own and suffered no side-effects, unlike him and his team who performed a similar surgery and were banished to the Game World when they extracted Parado from Emu.
- Villains Out Shopping: After capturing Poppy, she lounges at a mansion's backyard and snacks on cherries next to Kuroto.
Portrayed by "Harry Sugiyama" (Henry Sugiyama Adrian Folliott Scott-Stokes Jr.)
An American gamer who takes a liking to Nico. He is admitted into Taiga's hospital upon displaying symptoms of Toki Meki Crisis game disease, concurrent with the revival of Saki Momose and her new boyfriend Lovelica, the Toki Meki Crisis Bugster. He appears in Kamen Rider Brave & Snipe, the first installment in Kamen Rider Ex-Aid Trilogy: Another Ending.
- Abhorrent Admirer: The first thing he does upon meeting Nico is to lunge at her while excitedly talking about how he is glad he found her.
- Nerd Glasses: He wears a pair of these.
- Put on a Bus: His role in the story ultimately results in this happening to Nico, who moves to America with him.
- Shout-Out: His surname alongside Nico's given name make a joint reference to Nicole Kidman.
- What Happened to the Mouse?: The Tie-In Novel ~Mighty Novel X~ reveals that Nico returned to Japan with Taiga three years after the events of the V-Cinema trilogy; there is no mention of Luke.
Another Parado/Kamen Rider Another Para-DX
Portrayed by Shōma Kai
Parado's doppelgänger who shows from the Game World of Saiko Yaotome's Let's Make Bugsters test run and impersonates the real Parado. He traps the real Parado and uses the Gashat Gear Dual Another to transform into Another Para-DX. He appears in Kamen Rider Para-DX with Poppy, the second installment in Kamen Rider Ex-Aid Trilogy: Another Ending.
- Arc Villain: He's the main threat of Kamen Rider Para-DX with Poppy, but that special is only part two of the Another Ending trilogy, which has Kuroto Dan as its overall Big Bad and Final Boss.
- Co-Dragons: He and a data copy of Genomes (Dr. Pac-Man's monster form) are this to Saiko Yaotome.
- Cover Identity Anomaly: While impersonating the real Parado, his video game skills are noticeably less impressive.
- Devour the Dragon: He ends up absorbed into a Bugvisor following his destruction and then injected into Kuroto so Kuroto can use the power of the original Bugster virus to create God Maximum Mighty X.
- Evil Twin: To the real Parado. A self-absorbed jerk that sees no point in anything else but games and reacts violently to being beaten in them. Essentially Parado with all his bad features enhanced and with absolutely no redeeming ones.
- Evil Wears Black: His outfit is completely back from head to toe. His suit as Another Para-dx is also also black and grey save for the eyes.
- Greater-Scope Villain: Retroactively, he is one to the main story, as he is the version of the original Bugster virus that allowed Masamune to become Cronus.
- Mirror Match: Naturally, Another Para-DX fights Para-DX.
- Palette Swap: A black recolor of Para-DX Perfect Knock Out Gamer Level 99, except he uses the Gashacon Bugvisor II (itself a Palette Swap of the first Gashacon Bugvisor) instead of the Gashacon Parabraygun.
