These characters that don't truly fit in the other categories. Their origins differ heavily as a result.
Unknown Thief (Ratchet & Clank)
The real identity of the thief is Angela Cross, but she's been missing since the events of Deadlocked, yet someone has found her attire and is using it as a disguise for their own agenda. There's actually two sharing the outfit: Nora Valkyrie, and Kairi.- Anti-Villain
- Blood Knight: She's this when Nora is in the attire.
- Red Oni, Blue Oni: The thief has two incarnations depending on who's wearing the attire; Nora is the red, and Kairi is the blue.
- Samus Is a Girl: This thief, like Angela, is female.
Courtney Gears (Ratchet & Clank)
A sadist Evil Diva working for Dr. Nefarious. She's allied with the proxy, but apparently has different agendas.- And Your Little Dog, Too!: Gears abducts a seriously ill Sora to torture him and punish Ratchet for what happened in Obani Draco.
- Arc Villain: She's the antagonist of the third act of "Muse Hysteria" before Tachyon is summoned.
- The Bad Guy Wins: While indirect, she succeeded in harming Sora with the Cursed Coach, which started the chain of events that lead to his leg amputation.
- For the Evulz: This is one reason why Gears joined the Darkness Proxy.
- It's Personal: The other reason why she joined. Gears did not take her defeat and disgrace at the hands of Ratchet very well, and also resents Sora for defacing her lair (by accident).
- Karmic Death: When Ruby and Carmelita save Maxwell from the asylum, Gears summons the Cursed Coach to stop them from escaping. Said Unversed drops a bomb onto the Evil Diva and her dancers as they gloat, killing them in a matter eerily similar to Lady Tremaine and her daughters.
- Not-So-Harmless Villain: Gears shows she's no spring chicken when she ambushes and corrupts Tron into serving the Proxy, and causes Ruby's Heroic BSoD at the same time. Much later on, she learns of Sora's temporary weakness, and exploits it, and would've killed him had she not gloated on TV, allowing Carmelita to track them both down.
- Psycho for Hire: For the proxy. It is also implied that Gears is secretly an ally of Master Xehanort, and has plans to hand the Princesses of Heart (and Tachyon) to him.
- Uncertain Doom: She and her two remaining dancers were burned alive inside the asylum, and are still missing as of Rainbow Rivalries.
- Villainous Breakdown: She snaps when Sora unwittingly vomits inside her temple.
Prince Hans (Frozen)
The 13th in line to the Southern Islands' throne, and driven to villainy out of resentment towards his elder brothers, Arendelle, and dozens of other kingdoms who kicked him out.- Bad People Abuse Animals: Hans is willing to decapitate a Pokémon in the midst of his Villainous Breakdown. The Pokémon in question is an Audino.
- Did Not Think This Through: So, Hans...your plan on Getting the Iron Giant pissed off through Elena using Mitsuzane's Sengoku Driver resulted in collateral damage and mentally scarred gods, not to mention throwing Yugi's reputation into the mud even more after he used the Egyptian Gods to incinerate anyone who could stop the asylum along with causing Elena to kick your teeth in when she found out. Be very glad that you being shipped back home was your punishment.
- Evil Cannot Comprehend Good: He hates Jak because he can't understand why the latter, a Fallen Prince, has lived a (mostly) happy life.
- Evil Counterpart: To Jak, right down to both having a Superpowered Evil Side.
- Evil Is Petty: Joined the Darkness Proxy to get revenge on Elena and Gentaro because he got jealous that someone like Gentaro had the hand of Elena (a princess). Neither of them liked that reasoning at all.
- Foil: Hans is set up to be one for Penelopenote and Jaknote .
- Green-Eyed Monster: Was jealous of Jak and Gentaro for different reasons. The hatred of the latter was so much that he was the one who would set up the Iron Giant's rampage.
- Hated by All: Everyone in the pantheon hates him.
- Hate Sink: In-universe. Hans didn't have good reputation initially, but his spite-fueled alliance with the Proxy — which includes his petty reason to cause Gentaro's despair — and trying to chop Audino's head off ultimately has him replace Mitsuzane as the main target for the angry mob.
- Heel Realization: After calming down, and being called out by Uncle Howie over his crimes against the pantheon, Hans realizes what an ass he was to everyone, and surrenders, admitting he's let The Power of Hate consume him.
- Kick Them While They're Down: Hans has now qualms about attacking a wheelchair-bound Riku near the end.
- Late-Arrival Spoiler: The film's Plot Twist in Hans being an Evil Prince and a Manipulative Bastard is open here.
- My God, What Have I Done?: After his attempts to kill Jak ends in him snapping and attacking an innocent Pokémon before cutting an oxygen tube to keep Riku in a stable condition, Hans calms down and horrified on how he allowed his jealousy to control him and become a Hate Sink to everyone and it gets worse when word spreads on how he made Elena trigger the Iron Giant's rage.
- The Resenter: He's still holding a grudge against Anna and Elsa for what happened in Arendelle.
- The Usurper: His main goal is to marry into a royal family, kill them off in secret, and become the new King. It is hinted that he tried this with several kingdoms, including Dalmasca and Haven City. He was kicked out and declared Persona Non Grata in all cases.
- Villainous Breakdown: Busted in his attempts to kill a comatose Jak, Hans tries to decapitate Audino before slashing a breathing tube Riku was wearing to slow him down. He's pulled out by Carmelita's ape mercenaries while cursing both Riku and Jak.
- What Happened to the Mouse?: Hans' fate after "The Friendship Asylum" is not revealed, but one line in Diamond Adventure implies he was sent back to the Southern Isles. This was intentional, as a sequel to Frozen has been announced, and the authors don't want contradictions.
Emperor Percival Tachyon (Ratchet & Clank)
Spoiler character from "Muse Hysteria". A Cragmite who purged the Lombaxes and brought the Polaris Galaxy into a fascist dictatorship for 20 years before Ratchet defeated him.- Bad Boss: If one of his lines during the Final Boss indicate, Tachyon mistreated the Drophyds, viewing them as disposable, and doesn't show any emotion when he tells the party that King Triton killed them all sometime after the Battle of Fastoon.
- Big Bad: Of "Muse Hysteria"
- Dark Is Evil: His species are Pureblood Heartless originating from Ratchet's unnamed universe when the World was divided during the Keyblade War.
- Eviler than Thou: He's an Absolute Xenophobe, A Nazi by Any Other Name, an Omnicidal Maniac, and Made of Evil. Even the Proxy consider him a monster. Tachyon is also one of the few to surpass Xehanort in evil.
- Feeling Oppressed by Their Existence: He hates everything that isn't his species, but his main target are the lombaxes, given they banished the Cragmites in the past. He also hates Keyblade Wielders because his species are weak to them.
- King Mook: Inverted. Tachyon is fairly weak compared to most Cragmites/Heartless, physically wise, and has to rely on other Cragmites to do the fighting. But when he has to fight on his own, watch out!
- Knight of Cerebus: Compared to the Proxy and Courtney Gears, Tachyon is dead serious on using the Cragmites to take over the pantheon.
- Made of Evil: He's a Heartless, after all.
- Sealed Evil in a Can: Courtesy of the Princesses of Heart, he was trapped in the Realm of Darkness until the proxy set him free. He's banished again at the end to the Pride Lands.
- Villain Team-Up: Discussed. Courtney Gears admits in The Friendship Asylum that she had plans to take Tachyon to Master Xehanort to see what happens if they team-up. Fortunately, she's stopped before it happens.
- Walking Spoiler: Oh boy...
Penelope Mouse (Sly Cooper)
A disgraced former member of the Cooper Gang, and Bentley's ex-girlfriend.- Cassandra Truth: Penelope does show everyone the video of Mitsuzane's torture, but it was a complete accident. Unfortunately, she's so well-hated, that the pantheon assumes that she's working for the proxy to get even with the Cooper Gang, so nobody is willing to listen to her. It's reached the point where Riku punches her in the face.
- Dark Is Evil: Sora detects a strong amount of darkness in Penelope's heart when he first sees her. It leads to the point where Heartless spawn after she escapes jail, intending to distract her enemies.
- The Dragon: She's hired by Clu to serve as his observer in the analog world and help with his eventual quest for "perfection". Penelope is Only in It for the Money, and is known to have sold some of his blueprints to both Melkor and Lucifer. Clu, on the other hand, generally cares for Penelope.
- Even Evil Has Standards: Like most villains, she views the Darkness Proxy as a threat, and is even willing to team-up with her ex-boyfriend turned rival Bentley to stop them.
- Evil Former Friend/Psycho Ex-Girlfriend: To the Cooper Gang for the former, and to Bentley for the latter, whom she tried to murder in Thieves in Time.
- Foil: Penelope serves as an anthesis to Prince Hans. Both are villains who pretended to love other people for their own selfish desires (Hans with becoming King of Arendelle, Penelope with wealth and world domination). Penelope would never think of teaming up with the Darkness Proxy to get revenge against the Cooper Gang, but ended up helping them by accident, and everyone assumes the worst. Hans as Sköll intentionally sets the Proxy free without being detected, and nobody assumes he's working with them until he attempts to kill Jak, all in the name of revenge against Elsa and Anna, and getting the kingdom he desires. In the end, Penelope ends up an even worse villain, while Hans stops antagonizing the pantheon.
- I'll Kill You!: Penelope grows to hate Sora for being friends with Bentley, and swears she will kill him. Sora hardly pays notice.
- Not Me This Time: The Cooper Gang suspect that Penelope is a secret ally of the proxy, and was the one responsible for Sly being corrupted. She isn't, and only helped them out by accident, but they still won't believe her.
- The Rival: To Bentley following their nasty break-up.
- Savage Wolf: Penelope's robotic wolf minions from the 14th century appear working for a large wolf Heartless called Sköll, which causes Jak to believe Sköll is Penelope's Heartless. They're working for Hans, a rival and implied Love Interest of Penelope, and Sköll is Hans' Heartless.
- Treachery Is a Special Kind of Evil: Her betrayal of the Cooper Gang isn't doing Penelope any favors when it comes to proving herself innocent. Even Sora, who can always see the good before the bad in people's hearts, sees nothing in Penelope and attacked her at first sight.
- Villainous Breakdown: She's humiliated by Uncle Howie in Act Two, and is thrown in jail and taunted by Sora, Donald, and Goofy. After escaping during the Slamwitch rampage, she curses Sora and Bentley at the top of her voice and ignores Clu when he tries to contact her.
Neyla/Clock-La (Sly Cooper)
A former Interpol inspector who was secretly a Klaww Gang member alongside Dimitri. She had betrayed her mentor, Arpeggio, and merged with Clockwerk to become Clock-La, but died before she became truly immortal. Now she wants to use the asylum for her own gains, and is manipulating Oogie Boogie for her own gains.- Cats Are Mean: Compared with Riku's Absol, Neyla is one mean feline who only cares for herself.
- Chronic Backstabbing Disorder: She is merely a freelance villain who used all sides to her own advantage. At one point, she even teamed up with Kairi and Team JNPR for her own selfish desires.
- Nice Job Fixing It, Villain: All she accomplished here was purifying Sora and Jaune; with both defeated, the asylum is left defenseless, and in anger, it throws Neyla into an oubliette, where she remains trapped until it is destroyed.
- The Rival: To Jack Skellington.
- The Starscream: Neyla's goal is to overthrow the Guardians, become the new leader through You Kill It, You Bought It, and use the All-Star Power to achieve immortality as Clock-La by building a new body with parts stolen from Dr. Finkelstein.
- Uncertain Doom: Neyla was trapped inside the asylum during the last 1/4 of The Friendship Asylum, with her fate not revealed until Diamond Adventure, where it's revealed she climbed out of the oubliette and escaped after the asylum was burned down, but before the Heart was destroyed.
Humongous (Labyrinth)
The guardian of the Goblin City, who's really just a tiny goblin controlling a large mecha from its head. Both Humongous and the mecha are captured by the Proxy to keep Queen Chrysalis imprisoned, leading to Jareth being involved.Perry the Parasol (Super Mario Bros.)
A boy turned parasol that is friends with Princess Peach who ends up in various (and painful) predicaments.
- And I Must Scream: As he's a parasol, he has limited movement. He's shown in the final story screaming and crying for someone to save him when he gets stuck in Limbo.
- Break the Cutie: Literally in The Friendship Asylum as Yugi snaps him over his knee before setting the boy on fire.
- Equippable Ally: Downplayed. He isn't really an "ally" to Kaiba as he's more being babysat by the CEO as a promise to Princess Peach but Kaiba is rarely seen without the parasol in the final story.
- Grievous Harm with a Body: He can be used as a weapon to lay the smackdown on enemies. Kaiba uses him in the final story in a sword fight against Jeff Hardy (in his Willow persona).
- Hypercompetent Sidekick: Downplayed. Kaiba is pretty strong and smart a fighter as it is, but Perry's abilities come in handy throughout the final story. Case in point: his Bowlbrella technique lets him swim across the Lake of Reincarnation—which, if one submerges into it gets temporarily stuck as a previous form of themselves—and rescue Mokuba without problem.
- Intergenerational Friendship: With Seto Kaiba in the final story.
- Kill It with Fire: Again, he's set on fire by Yugi in The Friendship Asylum.
- Parasol of Prettiness: His current form.
- You Remind Me of X: Kaiba's friendliness with Perry is most likely due to the parasol reminding him of Mokuba. Fittingly, when Mokuba arrives in Through Darkness and Mirrors, they get along splendidly after Mokuba gets over the weirdness of his brother communicating with a talking parasol.
Uncle Howee (The Haunting Hour)
The host of an old TV series called "The Uncle Howee Show" who pops up from time to time to teach bullies a lesson.
- Beware the Silly Ones: He may seem like a goofy oddball show host, but he's a very scary Reality Warper capable of luring people into his show and making them puppets.
- Crossover: In-universe; he teams up with The Muppets to unleash karma on Penelope and Prince Hans for their atrocities.
- Friend to All Children: As crazy and malicious his methods can be, he honestly loves his kid fans. This is why he teams up with The Muppets to apologize for trying to behead someone.
- Marionette Master: He can turn a god into a lifesize puppet. Whether or not the puppet is even conscious is debatable.
- Pass the Popcorn: He's eating popcorn when Artix and (a brainwashed) Voltaire fight in Muse Hysteria. Lampshaded by Crash McLarson when he asks if Uncle Howee is going to share.
- Reality Warper: He's usually seen on a television screen but can pop out into the real world, making it as loud and wacky like his show, teleport from one place to another and even turn people into puppets.
- Surveillance as the Plot Demands: Is capable of turning television screens on and off so he can keep an eye on any and all bullies to keep an eye on.
- Would Hurt a Child: He tries to behead Mitsuzane (Age 15-16) on live television in Muse Hysteria.
The Slasher/Sota
A black hooded figure known for the slash marks he makes on his targets with his sword. Reveals himself in Through Darkness and Mirrors as Gentaro's detached goodness, an indicator that Gentaro is still alive who has news that, if the Pantheon doesn't figure out something soon, Limbo is going to consume them and he himself is living on borrowed time.
- Animal Motif: Has two of them.
- (Pre-hood removed): Snakes. He wears a black hooded cloak, his facial scars are like scales, and him fading away is like him shedding skin.
- (Post-hood removed): Coyotes. He wears a mask styled after one and he's mistaken for "Grandpa Coyote" (the Aztec God Huehuecoyotl) by the residents of Limbo because of it.
- Anti-Villain: Type II. He's stuck this way due to the Darkness within Limbo corrupting Gentaro and he's unable to do anything about it.
- Beneath the Mask: He actually doesn't like what he has to do, but only does it so he can save the Pantheon and figure out a way to reunite with Gentaro.
- Berserk Button: Destroying or insulting his Dark Synchro monsters, especially Muñeca, will be your worst mistake.
- He also dislikes being called garbage/trash/waste, etc.
- Black Cloak: Constantly wears one, no matter the situation and weather. It is based off of the cloths hanging on Lady Muñeca's arms. It's to keep his similarities to Gentaro hidden.
- Brutal Honesty: Does not sugarcoat on Yugi that what the boy did in Muse Hysteria has become the catalyst for the final story.
- Calling Your Attacks: Has to call out the type of ability he wants his cloak/katana to enact ranging from elements ("Fire", "Elec", "Water") to stranger utilities ("Pen", "Smoke", "Spike", "Chainsaw")
- Came Back Wrong: Something had to happen for Gentaro's good half to turn out...off.
- Catchphrase: "Is that so?" combined with a Quizzical Tilt.
- Character Tic: His Catchphrase and Quizzical Tilt combined with an arm under his chin and the opposite hand holding the elbow. If his mood is light-hearted, his head is tilted to the right with the right hand under the chin. If he's sarcastic or pissed off, he tilts his head to the left and his arms switch positions.
- He also flicks the katana out of its sheath then back in to replicate the "tick tock" of a clock.
- He also likes smoothing back his hair (even with a hood on) That's one of Gentaro's tics.
- Cool Mask: After he is transferred into Kaiba's Duel Disk then later given his own body, he dons a coyote mask.
- Creepy Doll: Wields a Karakuri deck when he duels Yami and Joey and has the Maidens of Mictal by his side. He also is described with the physical appearance of one with skin the color of porcelain.
- Creepy Good: A black cloak wearing person who speaks in a collection of Double Entendres and his monsters are collection of Creepy Dolls, not to mention that he is the goodness of Gentaro's soul given human form.
- Curb-Stomp Battle: His duels have him flat on his ass. He doesn't last 2 turns with Kaiba (although he was only dueling to cause a distraction).
- Dark Is Not Evil: Wears black, uses a dark sword, has Dark Synchro monsters, but is Gentaro's goodness and he's kooky, dorky, and just really wants to befriend others. Ironically this makes him nicer than the real thing, since Gentaro himself is being corrupted by a shard of the darkness within Limbo.
- Double Entendre: His dialogue to Yugi and Joey in Act I of Through Darkness and Mirrors just reeks of this. He's actually trying to provoke Yugi into using the Keystone of Limbo that's in his soul, but to everyone else, it looks like he's some Stalker with a Crush.
- Early-Bird Cameo: Appears in the final scene (un-named) in "Shattered Illusion", talking to BROKEN Matt.
- Eviler than Thou: In a way, he's actually worse than Alt!Gentaro... and he's supposed to be Gentaro's goodness.
- Expy: Of Roxas, bearing a smiliar look to the friendly protagonist and the angst he has on trying to be a person (or rather reunite as a person). He even states that he is like a Nobody.
- He also shows some similarities with Hector Rivera too.
- Facial Horror: He has burns on his face patterned after snake scales. They gradually form cracks as a reminder that he is breaking apart if he doesn't reunite with Gentaro.
- Foil: Of Alternate!Gentaro since both of them are alternate versions of the true Gentaro Kisaragi, both are fans of the corruption, both are vastly different from the original Gentaro Kisaragi with black clothes and have a penchant for mad laughter. Their attitudes toward Yugi are different; the former shows remorse for initiating the plan that would make Yugi send the CMC to Limbo, the latter does not give a shit as to Yugi's mental health if he can squeeze the Keystone of Limbo out of the boy. Moreover, The Slasher is part of the original Gentaro.
- Gone Horribly Right: He's supposed to get Yugi to activate the Keystone of Limbo...but he wasn't expecting the pressure that all the other gods have hounded on the boy for six months that causes Yugi to nearly kill him...and then immediately collapse from exhaustion and ruin his plans.
- Identical Stranger: Everyone comments how he looks like Gentaro, but he corrects them by saying he looks "sort of" like Gentaro. Justified; he's Gentaro's goodness.
- I'll Kill You!: Repeats this over and over against n as he strangles Kaiba after the later destroys the Lake of Reincarnation.
- Insistent Terminology: Has to tell gods that he doesn't look exactly like Gentaro, but "Sort of" like Gentaro. That's because he is Gentaro's goodness.
- In the Hood: Usually keeps his appearance covered by the hood of his black cloak.
- Jekyll & Hyde: To Gentaro himself. Sota is actually all that is left of the goodness in Gentaro's soul since the darkness within Limbo has been feeding the real Gentaro nothing but negative emotions and corrupting him.
- Katanas Are Just Better: Wields a katana as his weapon that can be enchanted with different elements.
- Spell Blade: The elements include fire, electricity, ice, water and air. Because he's using the Astroswitches that has those elements.
- Large Ham: He's loud, bombastic, laughs at everything and everything and loves being dramatic. Fitting that he's Gentaro's goodness who is also a huge ham.
- Laughing Mad: After he sees Yugi give into his hatred, empowered by the Keystone of Limbo, he starts laughing.
- Cry Laughing: By the time all of the plans to get the Keystone have failed, he breaks down into this.
- Manipulative Bastard: Ooh is he ever. His debut chapter in Through Darkness and Mirrors is him using his Karakuri deck to Troll his opponents and get them to the position so that he could 1) brainwash Joey and 2) destroy the Spellbinding Circle card that is trapping Yugi, so he can get Yugi to become corrupted by the Keystone of Limbo.
- Meaningful Name: Sota is from "Sort of" because of how he looks "Sort of" like Gentaro.
- Tuckerization: He's actually named after Gentaro's actor (Sota Fukushi).
- Mistaken for Gay: His Double Entendre towards Yugi and Jounochi have people think he's this and this gets exasperated due to his No Social Skills and, when in Limbo and in disguise as Huehuecoyotl (who was well known for being a god of male beauty) thinks that the YGO characters with him are his..."party". Since he's a part of Gentaro, it's revealed that he only has eyes for Elena.
- Mythology Gag: Being compared to "trash" is from the first episode of Fourze; Miu calls Gentaro "Trashiest of Trash" (in English) and Gentaro thinks that she's calling him "Manliest of Men".
- No Social Skills: Nearly anytime he's talking to Yugi, it ends up as That Came Out Wrong and sounds like he's a Shipper on Deck for Yugi and the Pharaoh or Yugi with either Kaiba or Joey (or something more). It's later revealed that most of his stunted social skills comes from figuring out how to explain "Yugi, you have a time bomb inside your soul" without 1) causing attention and 2) killing him.
- Phrase Catcher: Being told that he looks exactly/just like Gentaro to which he replies that he look "sort of like Gentaro".
- Swiss-Army Weapon: His cloak can transform into a variety of weapons. It's because he uses the Fourze Driver as the basis for it.
- Villainous Breakdown:
- Unleashes this during his final turn in his Duel against Yami and Joey. And it turns out to be a bad thing since it makes him too unhinged and not understanding that Yugi honestly wants to kill him.
- Unleashes this once more after Kaiba evaporates the Lake of Reincarnation and foregoes the katana to strangle the guy.
- Walking Spoiler: His real identity plays a pivotal role in Through Darkness and Mirrors.
- Woobie, Destroyer of Worlds: Why is he causing so much trouble and harassing Yugi? He is Gentaro's goodness that was ejected when Limbo wormed its way into the real Gentaro and he need the Keystone so Limbo will be pacified or else both he and Gentaro will fade away and classify themselves as obsolete. He honestly wants to explain this, but knows that his appearance as someone who looks like Gentaro won't be accepted, and explaining that the real Gentaro and Elena are causing an extreme plan involving the Cutie Mark Crusaders will mean that he will be persecuted.
