* ''Franchise/{{Frozen}}'': [[EvilColonialist King Runeard]] [[labelnote:Appearances]]''WesternAnimation/FrozenII''; ''Literature/DangerousSecrets''; ''Literature/PolarNightsCastIntoDarkness''[[/labelnote]], former king of [[Characters/FrozenArendelle Arendelle]], was the father of Agnarr and the grandfather of Anna and Elsa. Runeard was abusive towards his wife and child, eventually causing the former to leave him, with Runeard blaming this on "evil spirits". Runeard eventually encountered the [[Characters/FrozenNorthuldra Northuldra]] tribe and [[FantasticRacism feared them for their use of magic which could threaten his power]], so he built a dam to drain their resources and force their submission while lying about it as a peace offering. This dam would also threaten the nearby kingdom of Vesterland with starvation. Realizing this, its two princesses, Sissel and Ingr, refused to help fund the dam, and when Sissel died in a flash flood, Runeard forced the only witness to lie that Ingr "murdered" her sister, attempting to execute her to eliminate any opposition to his project. When the Northuldran chief showed concern over the dam, Runeard killed him in cold blood and waged battle on the Northuldrans, killing many on both sides. [[PosthumousCharacter Even after his death]], his actions would continue to haunt all involved.

* [[Characters/KingdomHeartsVanitas Vanitas]], Number XI of the [[Characters/KingdomHeartsOrganizationXIII Thirteen]] Seekers of [[DarkIsEvil Darkness]], desires to [[OmnicidalManiac spread Darkness across all worlds]]. His first known attempt would be by possessing [[Characters/KingdomHeartsVentus Ventus]] and forcing him to kill Strelitzia and take her place as a union leader, causing Ventus to be haunted by nightmares of the deed and tricked into thinking he did it of his own will. Vanitas would then attempt to use Ventus and the data works as means to grow stronger and consume more worlds along with his brethren. After gaining his own body as Vanitas, he would become [[Characters/KingdomHeartsMasterXehanort Master Xehanort]]'s apprentice and be the forerunner in his cataclysmic plan to restart the Keyblade War by having the Unversed beings inside his body cause destruction across multiple worlds to lure Ventus from home, so he could torment and goad him into fighting him to forge the X-Blade and take over his body so he could begin a war that could "reduce all worlds to nothing". Returning once again for another Keyblade War via time travel, Vanitas restores his heart with the negative emotions of children and begins tormenting his "brothers" [[Characters/KingdomHeartsSora Sora]] and Ventus again so he can once again claim Ven's body. In his final moments, deciding to [[RedemptionRejection reject redemption]] from his brothers despite having the capacity to do good, Vanitas shows himself to be the worst out of all the villains in the ''Kingdom Hearts'' universe.

** ''Manga/KingdomHeartsI'' & ''[[Manga/KingdomHeartsChainOfMemories Chain of Memories]]'': [[TheManBehindTheMan Ansem, Seeker of Darkness]] is the Heartless form of Xehanort. Masterminding the [[Characters/KingdomHeartsHeartless Heartless]]' invasion of several worlds and Maleficent's plan to capture the Seven Princesses of Heart in order to open the Final Keyhole, Ansem [[MindRape Mind Rapes]] Riku so that he can possess his body. He stabs Maleficent with a Keyblade in order to destroy her once she's [[YouHaveOutlivedYourUsefulness no longer of use to him]], and then deceives Sora into using that same Keyblade to make what would ultimately be a SenselessSacrifice, turning [[Characters/KingdomHeartsSora Sora]] into a Heartless and unsealing the Final Keyhole. When [[Characters/KingdomHeartsRiku Riku]]'s heart fights back from within to stop him from attempting to kill [[Characters/KingdomHeartsKairi Kairi]], Ansem uses his power to banish Riku's heart into the Dark Realm. Ultimately planning to open the Door of Darkness to let darkness consume all existence, Ansem shows nothing but glee towards his destructive ambitions. Returning after defeat as a specter within Riku's heart, Ansem attempts to play the boy's own emotions against him in order to take control of the boy's body once more, vicious to the end. Showcasing no redeeming features and [[VileVillainSaccharineShow played dead seriously against the manga's usually lighthearted and silly tone]], Xehanort's Heartless would do whatever it took to gain ultimate knowledge and power, and to [[DrunkOnTheDarkSide sate his undying hunger for darkness]].
** ''Manga/KingdomHeartsII'' & ''[[Manga/KingdomHearts358DaysOver2 358/2 Days]]'': [[NotSoWellIntentionedExtremist Xemnas]], the Nobody form of Xehanort and leader of [[Characters/KingdomHeartsOrganizationXIII Organization XIII]], is portrayed as a cruel sociopath who rules his organization without care for any of its members, viewing his followers as weaklings who are only fit to serve his purposes. Looking to exploit the Keyblade's power to claim hearts, he allows [[Characters/KingdomHeartsRoxas Roxas]] and [[Characters/KingdomHeartsXion Xion]] to grow close, intending to then pit them against each other so he can judge which Keybearer would be more useful to his plans, even tampering with Xion's form, [[MindRape Mind Raping]] her and sending her to her death. When Axel is sent to look for the runaway Roxas, Xemnas threatens to eliminate him if he doesn't bring Roxas back dead or alive. He later attacks the Radiant Garden with hordes of Heartless, almost getting Goofy critically injured in the process, just so [[Characters/KingdomHeartsSora Sora]] and King Mickey can slay them all and give him enough hearts to complete his own Kingdom Hearts. When Ansem the Wise and Mickey try to stop his plans at his castle, Xemnas orders his Nobodies to kill them, and proceeds to overtake the Great Heart from within in an attempt to [[OmnicidalManiac reduce all of existence to nothingness]] and destroy all those in his way. Cold-blooded, pitiless, and lacking his game counterpart's TragicVillain qualities, Xemnas continuously shows himself to be more monstrous than any other Nobody solely because [[ItsAllAboutMe he thinks it in his best interest to be so]].

** [[EvilCounterpart Mozenrath]] is the [[ArchEnemy most personal]], recurring foe that Aladdin has faced. A youthful [[EvilSorcerer sorcerer]] who betrayed, zombified, and enslaved his own master, Mozenrath enacts a variety of schemes to destroy Agrabah and bind Genie to his will. Attempting to unleash the Wind Jackal to annihilate Agrabah and threatening to do the same to every other kingdom of the world if they don't kowtow to him, Mozenrath later dominates the entire race of Sprites, turning them into a force of slaves that he works to near-death before trying to wipe them all out when they rebel. Mozenrath also traps a large portion of the Sultan's palace in an alternate plane of existence to be damned while he swoops in for control, and in another plot manipulated Genie and his girlfriend with dirty tricks so as to turn them into [[LivingBattery living batteries]]. In his final bout of villainy, Mozenrath horribly tries to [[GrandTheftMe bodyjack Aladdin]] and leave the boy hero trapped in either his own dying body, or inside Mozenrath's mind while he conquers the world.
** [[CatsAreMean Mirage]] is [[CardCarryingVillain evil incarnate]], devoted only to proliferating misery and destroying all that is good. [[EstablishingCharacterMoment As an early testament to her evil]], Mirage orders a village and its population incinerated in her debut just because of the crops they grow for the surrounding land. Mirage's plots range from the grandiose to the sadistically [[EvilIsPetty petty]], everything from attempting to have all of Agrabah destroyed and brewing up civil wars for fun, to trying to destroy Aladdin and Jasmine's love for each other by slowly transforming Jasmine into a snake. Mirage even tempts [[WouldHurtAChild children]] into her clutches, promising them immortality in exchange for becoming the monstrous El-Katib, a process she neglects to mention entails their eternal servitude in a dark void with release only ever three years. Mirage has no issue abandoning the El-Katib to die, coldly leaving them all to perish in the sunlight when one of them finally defies her.

* ''WesternAnimation/OneHundredAndOneDalmatianStreet'': [[CruellaToAnimals Cruella de Vil]], the one and only Devil Woman, returns in this series to seek revenge on the descendants of Pongo and Perdita. The decades since [[WesternAnimation/OneHundredAndOneDalmatians the original movie]] have turned Cruella into a harridan by harridan's standards who now acts with full regard to the Dalmatians' sapience. Cruella plans to [[BadPeopleAbuseAnimals mince all 99 of the puppies in her very own skinning machine]], intending to [[ForcedToWatch force their parents Doug and Delilah to watch]] the entire macabre process before turning them into "matching luggage". [[EvilAunt Cruella]] is also hideously abusive to her grand-nephew Hunter, at one point leaving him locked in a shipping container for six months with only dog food to eat, resulting in the poor kid undergoing SanitySlippage. When he finally snaps under her abuse, Cruella callously orders him caged up with the puppies.
