Other Universes

Nexus Palace

Tsukasa Kadoya/Kamen Rider Decade

Tsukasa Kadoya/Kamen Rider Decade

A mysterious man with the ability to travel between different parallel worlds. He keeps a close eye on the Kamen Riders of the Boiling Isles and Amphibia.

• Almighty Janitor: Even though Sougo is technically the one in charge, Tsukasa is the only one capable of traveling between worlds himself, so he does more work monitoring other universes more than Sougo does.
• Big Good: Tsukasa serves as a pseudo-mentor for the Riders he encounters, but he doesn’t get too involved because he doesn’t want to interfere with their personal journeys. He’ll still help out when the situation calls for it though.
• Dimensional Traveler: One of Tsukasa’s unique abilities.
• Omniglot: Thanks to his powers, Tsukasa gains the knowledge needed to function in any world he travels to, allowing him to speak languages like Spanish and Thai.
• Horrifying the Horror: Kamen Rider Decade’s Complete 21 form is so powerful, the Night orders King Andrias to stand down before they can even fight.
• Story-Breaker Power: Even compared to his fellow Riders, Tsukasa’s powers put him on a different level entirely. Unlike other examples of this trope, Tsukasa is fully aware of this, and he willingly chooses not to help out too much because he wants to see the younger Riders grow on their own. Of course, whenever a situation becomes serious (usually during a crossover), he’ll either help out a little, or send one of his allies to act as backup.

Sougo Tokiwa/Kamen Rider Zi-O

Sougo Tokiwa/Kamen Rider Zi-O

A young man who changed his own history so he never became the demonic tyrant Oma Zi-O. Now, he helps monitor the multiverse alongside his mentor Tsukasa and his “prophet” Woz.

• Big Good: While Tsukasa is the one who interacts the most with Luz and Anne, Sougo is the one in charge of the entire operation.
• Bystander Syndrome: While he was sent to help out during the climax of Kamen Rider X Kamen Rider Witch & Amp: The Dark Side of Hope, Sougo was told by Tsukasa to not get too involved with the conflict, even though with his reality warping powers, Sougo can easily take care of Oscura himself.
  Sougo: I know, Tsukasa-san, I understand your words. But... in this situation, with so many lives and worlds on the line...
• Foil:
  • To fellow veteran Rider Tsukasa. While Tsukasa is very lax and only steps in to help occasionally so he won’t disrupt the personal journeys of the younger Riders, Sougo is more concerned with helping people and only begrudgingly goes along with what Tsukasa told him to do by not finishing Oscura by himself. In addition, Sougo is much friendlier than Tsukasa is when he interacts with other Riders.
  • He also serves as this to Empress Oscura. Both of them started off as idealistic youths with their own dreams (Sougo to become a king, and Oscura to become a witch), and both stumbled upon a dark source of power. However, while Kamen Rider Zi-O’s powers were offered to Sougo by Woz, Oscura seized the power to become a Rider thanks to sacrificing people in the Sabbath ritual, and while Sougo managed to control his inner darkness with the help of his friends the closer he got to reaching Oma Zi-O’s level of power, Oscura slipped deeper and deeper into evil the stronger she got until she became the next tyrannical ruler of the Boiling Isles.
• Story-Breaker Power: Sougo is even more powerful than Tsukasa, but it’s for this reason that he isn’t allowed to simply end the threat of Oscura himself, much to his own concern.

Woz/Kamen Rider Woz

Woz/Kamen Rider Woz

The former prophet for the tyrannical Oma Zi-O, Woz has sworn loyalty to his younger self, Sougo.

• Character Narrator: Woz has taken on this role ever since his first appearance.
• Narrator All Along: Woz’s identity as the narrator was kept a secret during Kamen Rider Witch Alternative: The Ballad of Oscura, only revealing who he was at the end. Future installments where he narrated would have him introduce himself to the reader, similar to what he would do in his own series.
• Overshadowed by Awesome: Compared to the reality-altering Sougo and Tsukasa, Woz’s Rider powers aren’t nearly as powerful, but he is still able to keep up with his lord in a battle.

Showa Riders

Hongo Takeshi/Kamen Rider Ichigo

Hongo Takeshi/Kamen Rider Ichigo

The original Kamen Rider himself, who traveled with his associates to the Boiling Isles to take down the Shocker Coven.

• Big Good: He’s the precursor to every single Kamen Rider in existence, so it’s safe to say the respect he has among even his fellow Showa Riders is warranted.
• Crazy-Prepared: Before heading off to rescue Luz and Amity from the Shocker Coven, King asks Takeshi about stopping the attacks on the other ten Covens. It turns out that Takeshi already had the remaining ten Showa Riders split up to stop each assassination attempt on the Coven Heads.

Hayato Ichimonji/Kamen Rider Nigo

Hayato Ichimonji/Kamen Rider Nigo

One of Takeshi’s closest allies and a Kamen Rider himself. He was sent to defend Head Witch Raine Whispers of the Bard Coven.

• The Lancer: Like in canon, Hayato serves as the second-in-command to all the Showa Riders.
• Paper-Thin Disguise: What was Hayato’s disguise when he went to the Bard Coven? A fake goatee and ears.

Shiro Kazami/Kamen Rider V3

Shiro Kazami/Kamen Rider V3

The man who took down Destron in the name of his family. He was sent to defend Head Witch Eberwolf of the Beast Keeping Coven.

• Conspicuous Trenchcoat: His disguise.
• Hidden Depths: Surprisingly, he’s shown to understand sign language when Eberwolf uses it to thank him.

Joji Yuki/Riderman

Joji Yuki/Riderman

A former scientist for Destron and Kamen Rider V3’s partner. He was sent to defend Head Witch Darius Deamonne of the Abomination Coven.

• Adaptational Badass: Riderman never managed to defeat a monster on his own in canon, but here, he is able to defeat Pterodactyl Mummy.
• Missile Lock-On: Riderman’s Missile Arm, which was created for the fic.

Keisuke Jin/Kamen Rider X

Keisuke Jin/Kamen Rider X

The son of a robotics engineer who was converted into a cyborg to save his life, eventually becoming Kamen Rider X. He was sent to defend Head Witch Hettie Cutburn of the Healing Coven.

• Mysterious Protector: Unlike the other Riders, the Coven Head he was assigned to protect, Hettie Cutburn of the Healing Coven, never knew she was in danger.
  Keisuke: Hettie Cutburn. You were lucky to not to be involved in this. From one doctor to another, you're welcome.

Amazon/Kamen Rider Amazon

Amazon/Daisuke Yamamoto/Kamen Rider Amazon

A man who grew up in the jungle before becoming a “cyborg” thanks to the Gigi Armlet, and can transform into the savage Kamen Rider Amazon. He was sent to defend Head Witch Terra Snapdragon of the Plant Coven.

• The Speechless: Amazon says nothing other than when he calls his attacks, which makes his presence and sudden departure all the more confusing to Terra.

Shigeru Jo/Kamen Rider Stronger

Shigeru Jo/Kamen Rider Stronger

Unlike other Kamen Riders, Shigeru willingly let himself be transformed into a cyborg so he could rebel against the people who gave him his powers, Black Satan. He was sent to defend Head Witch Mason of the Construction Coven.

• Not Even Bothering with an Excuse: Shigeru wears the same clothes he normally wears (including the shirt with the large “S” on it), and doesn’t pretend he isn’t a human.

Hiroshi Tsukuba/Skyrider

A young man who loves to fly, both on his hang glider, and as a Kamen Rider. He was sent to defend Head Witch Osran of the Oracle Coven.

Hiroshi Tsukuba/Skyrider

• Mythology Gag: Hiroshi enters on a hang glider, one of his hobbies in canon.

Kazuya Oki/Kamen Rider Super-1

Kazuya Oki/Kamen Rider Super-1

An astronaut who became a Kamen Rider before he could venture to space. He was sent to defend Head Witch Vitimir of the Potions Coven.

• My Name Is Inigo Montoya: Kazyua introduces himself as “Kazuya Oki of the Sincere Shaolin Fist”.

Ryo Murasame/Kamen Rider ZX

Ryo Murasame/Kamen Rider ZX

The Rider who took down the Badan Empire with the help of his nine predecessors. He was sent to defend Head Witch Adrian Graye Verworth of the Illusion Coven.

• Mythology Gag: Ryo disguises himself as Adrian to get the jump on the Shocker Coven, similar to how he disguised himself as Kurayami Taishi in Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai.

Kotaro Minami/Kamen Rider BLACK RX

Kotaro Minami/Kamen Rider BLACK RX

One of the candidates to become the next Century King, Kotaro fought back as Kamen Rider BLACK, and later became Kamen Rider BLACK RX. He was sent to defend Emperor Belos himself.

• Small Role, Big Impact: While Kotaro fended off the assassination attempt on Emperor Belos, he was the one who got Hunter involved in the greater conflict.

Other Veteran Kamen Riders

Haruto Soma/Kamen Rider Wizard

Haruto Soma/Kamen Rider Wizard

An experienced Kamen Rider who wound up on the Boiling Isles. Unfortunately, he couldn't do much as the Demon Realm was trying to reject his magic, so he trusted Luz Noceda to take up the mantle of Kamen Rider after seeing her overcome her despair.

• Good Counterpart: He gives Luz the equipment needed to become a Kamen Rider, much like the White Wizard did for him in his show. The only difference is that Haruto isn’t Playing Both Sides here.
• Small Role, Big Impact: While he only appears during the opening arc, he is still the one who gave Luz her Kamen Rider powers in the first place, and he would also create a spiritual copy of himself to help Luz out.

Shoichi Tsugami/Kamen Rider Agito

Shoichi Tsugami/Kamen Rider Agito

A former amnesiac who saved the world from the Lords, now the owner of his own restaurant.

• 11th-Hour Ranger: Shoichi is recruited by Tsukasa to help defend Anne's Earth against the Night's invasion.
• Benevolent Boss: When Shoichi is called away for a mission as Kamen Rider Agito, he tells Mana (who works at his restaurant as his financial manager) to tell his other employees that he's closing the restaurant for the day, and will give them all the day off with pay.
• Retired Badass: Downplayed. Shoichi is still willing to help out as Kamen Rider Agito, but usually for big events that require a lot of Riders to fight.
• Unaffected by Spice: Where Grime screams in agony after trying some of the Boonchuy's cooking, Shoichi manages to handle the spice and praises Oum and Bee for their cooking.

Alternate Boiling Isles

Empress Oscura/Kamen Rider Oscura (UNMARKED SPOILERS)

See her page for more details.

Amity Blight/Kamen Rider Gato

Amity Blight/Kamen Rider Gato

The youngest child of the Blight family whose Everlasting Oath with Luz drove the young human down the path of darkness. At least, as far as she knows.Once Oscura’s reign is finally ended, Amity chose to go into self-imposed exile in the Human Realm with Luz as a way to atone for her actions, getting involved in the Desire Grand Prix a few years later.

• Adaptational Superpower Change: This version of Amity never became Kamen Rider Heka. Instead, she taught herself all kinds of magic in addition to Abomination magic, like Construction and Healing. She does become a Kamen Rider as part of the Desire Grand Prix, but she gains no additional magical abilities like the ones she had as Heka.
• Animal-Themed Superbeing: Kamen Rider Gato is themed after a cat.
• The Atoner: Amity believes that she is the reason why Oscura rules over the Boiling Isles, which is why she is determined to kill her, and then herself.
• Failure Hero: Despite countless efforts, Amity is never able to kill Oscura and atone for her crimes. It doesn’t help that Oscura herself sees it all as a game, as well as a way to find problems in her security system to improve, meaning that the more Amity fails, the harder it is for others to assassinate Oscura as well. Even in the Desire Grand Prix, she isn’t the one to defeat the Final Boss Jyamato, Luz is.
• My Greatest Failure: Amity views making the Everlasting Oath with Luz as this. When she competed in the Desire Grand Prix, her wish was to undo it.
• Normal Fish in a Tiny Pond: During her first round in the DGP, Amity is the only contestant to be a witch, meaning her magic is something none of the other contestants have.
• Poisonous Person: Kamen Rider Gato’s signature Raise Buckle during her time in the DGP was the Zombie Buckle.
• She's Back: In the final chapter of the Reprise Arc, thanks to Willow giving up her spot in the DGP, Amity is able rejoin and become Kamen Rider Gato again.
• Unwitting Instigator of Doom: Amity believes that casting the Everlasting Oath was what caused Luz to become Oscura, unaware of the role Lilith played to cause the Oath to go into effect.

Eda Clawthorne

Eda Clawthorne

Luz’s former mentor who would later serve as part of the resistance to find a way to stop Oscura.

• Adaptational Badass: This version of Eda never lost her magic, so she’s more capable of fighting on the front lines.
• Babies Ever After: After Oscura is defeated, Eda and Raine have a daughter they name Luz Anne Clawthorne-Whispers.

Little Luz

Luz Anne Clawthorne-Whispers

Eda and Raine's daughter.

• Cheerful Child: Much like her namesake, Little Luz is very optimistic.
• Locked Out of the Loop: While Eda told Little Luz about Luz's exploits in the Boiling Isles, since Little Luz is still a small child, she wasn't told about the atrocities Luz committed as Oscura.
• Small Role, Big Impact: Her existance means that in the future, Lumina, her descendent, will help Luz join the DGP.

Lilith Clawthorne

Lilith Clawthorne

The former head of the Emperor’s Coven who, in her attempt to one-up her sister, sabotaged her pupil Amity’s witches duel with Luz, something that would have grave consequences.

• Adaptational Wimp: Not only is Lilith’s magic drained completely like in canon, but her Palisman is destroyed as well.
• Karma Houdini Warranty: Lilith’s cheating wasn’t exposed for a long time, and she only faced karma when she got in the way of the very person whose life she ruined.
• Only Sane Woman: When Luz returns to the Boiling Isles in Oscura's Encore the Movie: Return to the Boiling Isles, Lilith is the only one of the Coven Heads who doesn't want to kill her.
• Unwitting Instigator of Doom: Lilith removing the power glyph from Amity meant that the witches duel Amity and Luz had was never stopped, and the Everlasting Oath started to take effect on Luz, causing her to go down the path of darkness into becoming Oscura.

Willow Park/Kamen Rider Honey

Willow Park/Kamen Rider Honey

The first friend Luz made in the Boiling Isles, later working to stop her after she became Oscura.

• Adaptational Badass: This version of Willow becomes a Kamen Rider as part of the Desire Grand Prix.
• Adaptational Relationship Overhaul: This version of Willow develops feelings for Luz.
• Animal-Themed Superbeing: Kamen Rider Honey is themed after a bee.
• The Big Damn Kiss: As Willow is sent back to the Boiling Isles after dropping out, she leaves Luz with this parting gift.
• Career-Ending Injury: Willow takes a serious blow from a Boss Jyamato, and it's part of the reason she lets Amity take her place in the DGP.
• Composite Character: Towards the end of the Reprise Arc Willow willingly gives up her spot in the DGP so Amity can take her place, just like Ittetsu/Kamen Rider Keilow did for Keiwa in Geats.
• Man of Kryptonite: Willow’s plant magic means she’s able to use it against the Jyamato, though she can’t use it for too long due to how complex they are as creations.
• Team Member in the Adaptation: While Willow never got involved with the CATs in canon, here, she joins the resistance along with Gus and Boscha.

Gus Porter/Kamen Rider Mirage

Augustus “Gus” Porter/Kamen Rider Mirage

One of Luz’s closest friends who later allied with the Witches Against the Throne alongside Willow.

• Animal-Themed Superbeing: Kamen Rider Mirage is themed after a chameleon.
• Adaptational Badass: This version of Gus becomes a Kamen Rider as part of the Desire Grand Prix.
• Luckily, My Shield Will Protect Me: Kamen Rider Mirage’s signature Raise Buckle is the Shield Buckle.
• Team Member in the Adaptation: While Gus never got involved with the CATs in canon, here, he joins the resistance along with Willow and Boscha.
• We Hardly Knew Ye: Gus only lasts two rounds before being eliminated.

Boscha/Kamen Rider Red-Pan

Boscha Barbtalone/Kamen Rider Red-Pan

The Alpha Bitch at Hexside, forced to take up arms against Oscura, if only for her own survival.

• Adaptational Badass: This version of Boscha becomes a Kamen Rider as part of the Desire Grand Prix.
• Adaptational Villainy: This version of Boscha is more sinister than in canon. Not only did she take advantage of Amity being in a coma by kissing her, she later attempted to rape Amity years later after drugging her with a potion. And eventually it’s revealed she wants to see Luz erased from existence. As in she her wish is that Luz was never born. When Luz has her on the ropes in Brighton, she swears that she’ll just make her friends suffer including her goddaughter if she’s sent back.
• Animal-Themed Superbeing: Kamen Rider Red-Pan is themed after a red panda.
• Asshole Victim: Being burned to death isn’t a pleasant way to go, but seeing it happen to Boscha after she tried to rape someone makes it very satisfying. It helps that everyone else who knew her was happy to learn what happened, even if it wasn’t permanent.
• Deader than Dead: Normally, a rider may be brought back after a round of the dgp. However since Boscha went and turned herself into a Jyamato during the zombie game, it’s safe to say she is not getting revived.
• Dirty Coward: As arrogant as she is, as soon as Luz and Sasha get the upper hand on her, she begs for her life before taking the chance to run away and escape Sasha's wrath.
• Epic Flail: Kamen Rider Red-Pan’s signature Raise Buckle is the Chain Array Buckle.
• Fantastic Racism: After her experience living under Oscura's reign, Boscha has very negative views on humans.
• Fatal Flaw: Her inability to understand people past her initial perception of them. Because of her experience living under Oscura's reign, she refuses to see Luz as anything other than the tyrannical and bloodthirsty dictator who stole Amity from her, not understanding Luz has come to regret her actions as Oscura while Amity genuinely loves Luz.
• Hate Sink: Boscha is a cruel and sadistic sociopath who has no qualms with manipulating others to get what she wants, to say nothing with how obsessive she is with Amity.
• Hated by All: After her attempted rape of Amity, everyone has a low opinion of her. When everyone gets to see their popularity ratings, Boscha is only as 1%. Come the final five and while the audience is cheering on everyone else, Boscha just gets booed with absolutely zero cheers. One time in the confession booth, she got booed by the audience. Even when one chapter had the readers vote on which contestant gave the best musical performance during a singing competition, Boscha tied for last with Sasha.
• Heel–Face Revolving Door: Boscha started off as a bully at Hexside who got involved with the CATs, and then became a Kamen Rider as part of the DGP, but took advantage of Amity’s presence in one round to try and rape her.
• Hoist by Her Own Petard: In an attempt to get strong enough to beat Luz, Boscha transforms with a Jyamato Buckle during their fight. Of course, during said fight, Luz was hesitant to fight back and risk being disqualified, but as soon as Boscha used the Jyamato Buckle, her status changed to that of a Jyamato, meaning Luz could fight back with everything she had.
• Karma Houdini Warranty: Boscha gets away with a lot of terrible things during her time in the DGP, but once her scheme to kill Luz herself falls apart, she gets subjected to not one, but three Curb-Stomp Battles at the hands of Luz/Oscura, Sasha/Soaron, and the Game Master/Glare respectively before finally being disqualified from the DGP.
• Rape Is a Special Kind of Evil: While in the Human Realm, Boscha attempts to rape Amity after drugging her with one of her potions.
• Team Member in the Adaptation: While Boscha never got involved with the CATs in canon, here, she joins the resistance along with Willow and Gus.
• Tragic Villain: While Boscha has shown herself to lack any redeeming qualities, it's clear that she was deeply traumatized by her time under Oscura's reign and hasn't been able to move on even four years later.
• Yandere: With how obsessed she is with Amity, it's not surprising that Marcy would call Boscha this trope.

Odalia Blight/Kamen Rider Fowl

Odalia Blight/Kamen Rider Fowl

The matriarch of the Blight family whose belief that a Blight never goes back on a deal ends up contributing to the rise of Oscura.

• Adaptational Badass: As short-lived as it was, Odalia becomes a Kamen Rider as part of the Desire Grand Prix. Later on, a Jyamato is made in her likeness, and she manages to hold her own against Amity for a while.
• Animal-Themed Superbeing: Kamen Rider Fowl is themed after an unspecified bird.
• Asshole Victim: Thrice.
  • After she blatantly admits she doesn't love her family, it's hard to feel bad for Odalia when Oscura brutally kills her.
  • She also gets no sympathy from Luz after a Jyamato kills her during the first round of the DGP, mainly because she kept trying to kill her.
  • While it was technically a Jyamato Rider replicating her likeness, Amity had no problems with killing her again to gain closure on her old life in the Boiling Isles, especially after "Odalia" tried to kill Amity herself.
• Energy Bow: Kamen Rider Fowl’s signature Raise Buckle is the Arrow Buckle.
• Never My Fault: During her attempt to kill Luz during the DGP, Odalia blames her for everything that went wrong in her life, blaming Luz for forcing her to confess how she doesn’t love her family instead of acknowledging that she had those feelings in the first place.
• Revenge Before Reason: Odalia is so focused on murdering Luz as revenge for what she did to her while she was Oscura, she is too fueled with rage to notice how many points she's losing, or the Jyamato about to kill her.
• Skewed Priorities: When Amity confesses to using an Everlasting Oath on someone, Odalia panics, not because of what could happen to the person Amity used the spell on, but because she's afraid of getting sued by the victim. Once she learns that the Everlasting Oath was used on a human child, she stops worrying entirely.
• Small Role, Big Impact: While her part in causing the Everlasting Oath to be bound was minimal, Odalia’s influence still stopped Amity from undoing it when she had the chance, which eventually led to Oscura rising to power.
• We Hardly Knew Ye: Odalia is killed in the middle of her first round in the DGP.

Lich

Emperor Belos/Philip Wittebane/Lich

An alternate version of Emperor Belos who becomes a Phantom after being defeated by Oscura. He travels to Amphibia to claim another version of Luz Noceda's magic so he can take back his throne back in the Boiling Isles.

• Adaptational Superpower Change: Rather than becoming a Kamen Rider, this version of Belos becomes a Phantom.
• Big Bad: Of Kamen Rider X Kamen Rider Amp & Witch: Heroes Unite!.
• Our Liches Are Different: Belos/Lich has the ability to resurrect the dead, and makes three dead Amphibian warriors into his servants, whether they want to or not.

The Collector

The Collector

An alternate version of the Collector who, after the death of Belos, conspires with Oscura.

• Adaptational Intelligence: Unlike in canon, he eventually sees through Belos' lies.
• Adaptational Villainy: The Collector in canon was dangerous, but he simply had no idea of how much harm he was causing, and ultimately saw the error of his ways. This version of the Collector is far less innocent, and is aware of how many people the Draining Spell will kill.
• Even Evil Has Standards: When the Collector tells Oscura about how there is an alternate version of Luz who is a hero with a happy life, Oscura's psychotic laughter at the realization that she’s the only version of her who is suffering is enough to slightly disturb him.
• In Spite of a Nail: The Collector is still betrayed by the ruler of the Boiling Isles, only instead of Belos, it's Oscura.
• The Unfought: Because the Collector is never freed from his prison, he never fights any of the Riders.

Alternate Amphibia

Anne Boonchuy/“BrokAnne”/Kamen Rider Calamity (UNMARKED SPOILERS)

Anne Boonchuy/“BrokAnne”/Kamen Rider Calamity

“I am destruction and emptiness, the enemy of all love. I am Kamen Rider Calamity. Now, let’s have some fun while we all burn together.”

^{Click here to see her Rider form's "First State".} "I'LL KILL YOU! I WILL... NEVER FORGIVE YOU!!!"

^{Click here to see her Rider form's "Second State".} "Just sit and rest there, Marcy. I’ll be back before I set the city on fire."

^{Click here to see her Rider form's "Third State".} "I wasn’t able to keep my promise, so, I’ll send Amphibia to you, Sprig."

An alternate version of Anne who awakened her powers and reunited with Sasha long before she met the Plantars. Not only did this prevent her initial Character Development, but the manipulations from the alternate versions of Sasha and Marcy drive Anne to commit more violent acts, growing more powerful until she becomes a walking calamity.

• Adaptational Badass: Anne gains control over the Calamity Gems long before the events of the finale, and unlike there, she manages to use them without killing herself.
• Adaptational Villainy: Not only does Anne ally herself with Sasha and the Toad Army, she eventually wipes out all of Amphibia and Earth with her powers.
• Adaptational Weapon Swap: Rather than a sword, Anne’s weapon of choice becomes a scythe which she names Azrael.
• An Arm and a Leg: Anne loses her left arm during a fight with Sasha, and gets a new one courtesy of Marcy.
• Became Their Own Antithesis: After being sexually abused by Sasha, Anne eventually does the same to Marcy once she rebels against Newtopia.
• Blood Knight: Anne becomes more focused on fighting and killing whoever gets in her way, eagerly embracing the blood of her victims at one point.
• Contrasting Sequel Main Character: Just like Oscura, Anne went down a darker path thanks to unlocking powers she didn't have the emotional maturity to control. The difference is while Oscura used a different source of magic to gain her powers, Anne simply unlocked her Calamity powers earlier than in canon, and later absorbed the powers of Marcy and Sasha. In addition, while Oscura usurped the throne after killing Belos and took control of the Boiling Isles with the Phantoms as her minions, Anne completely eradicated the Night and its forces and moved to destroy all of Amphibia in addition to Earth. Finally, Oscura was cleansed of her evil before the Gleeful Twins could recruit them to their cause, here, the twins made Anne their ally just as she unlocked the full power of all three Calamity Gems.
• Evil Counterpart: To Anne/Kamen Rider Amp.
• Invincible Villain: Once Anne gets the Calamity Gems, she becomes unstoppable thanks to the sheer power. Not even the Night is safe from her.
• Meaningful Name:
  • Kamen Rider Calamity is an appropriate name, seeing just how destructive her powers are.
  • Anne named her scythe Azrael, after the angel of death in some religions.
• Sanity Slippage: After everything that happens to her in the story: being betrayed by everyone around her, manipulated, cursed, mortally wounded, and raped? Let’s just say Anne goes more than a little insane and becomes nothing less than pure calamity in human form.
• Suicidal Cosmic Temper Tantrum: Anne eventually does this to her Earth after destroying Amphibia.
• Then Let Me Be Evil: Much like Oscura, the circumstances that this version of Anne had to face led to her embracing villainy.
  Olivia: You... You’re a monster...
  Anne: I am. A monster she and Sasha created, and you know what? I like it. I just don’t give a fuck anymore! I don’t care and it’s fucking amazing!

Sasha Waybright/Kamen Rider Bellona

Sasha Waybright/Kamen Rider Bellona

"Little Sasha doesn’t get to go home to loving parents, and a warm home. She’s all alone, and the only ones who fill that void in my heart, are you and Marcy. That’s why I’ll never let anyone else have you. Not your parents, not some warty little frogs, not anyone. And yeah, I don’t want to go back. I have nothing there worth going back to. But here, in Amphibia, we can rule as queens. You and I are the most powerful beings in this world. We could conquer all of it together! We could rule over this world as the three queens of another world, and I want you both at my side when that day comes!"

An alternate version of Sasha who gained access to her Rider powers much earlier, and as a result, let the power go straight to her head.

• Adaptational Badass: Sasha gains access to her Rider powers earlier than in the original fic.
• Adaptational Villainy: Sasha becomes much more bloodthirsty in this fic, not helped by her powers making it easier to hurt people with.
• Hate Sink: This version of Sasha has almost no redeeming qualities, being an abusive, vengeful sociopath.
• Rape Is a Special Kind of Evil: While not shown, Sasha has been said to do this to Anne after cursing her.
• Yandere: Sasha gradually slips more into this territory, outright threatening Hop Pop into making sure Anne doesn’t go to Wartwood again.
  Sasha: No one can have Anne. She’s mine, and only mine. Not this town’s, not her parents, she’s MINE!

Marcy Wu/Kamen Rider Ranger

Marcy Wu/Kamen Rider Ranger/Darcy

"Don’t worry, Anne. I’ll get us back home. Even if I have to cut off that bitch’s arms and legs and reduce her to a talking torso."

An alternate version of Marcy who was able to help Anne after her traumatic experience at the hands of Sasha... Until it was revealed that Marcy is no better in a way, manipulating Anne into helping King Andrias and the Night conquer the other worlds.

• Adaptational Villainy: Instead of being forcefully assimilated, Marcy willingly becomes the Core's host so Anne and Sasha wouldn't get hurt.
• The Quisling: This version of Marcy willingly lets herself be assimilated by the Core in exchange for Anne and Sasha getting spared.

Others

Mason and Mabel Gleeful (UNMARKED SPOILERS)

Mason and Mabel Gleeful

• Ambiguous Situation: While Mason and Mabel have their own Gaia Memories, it’s unclear if they can transform into Dopants, or a Kamen Rider like Kamen Rider Gemini.
• Evil Counterpart: To Dipper and Mabel/Kamen Rider Gemini.
• Greater-Scope Villain: After Oscura’s defeat, they seem to take up this role.
• Legion of Doom: Their goal seems to be recruiting Dark Riders for this very purpose.
