The Kingdom Hearts franchise are the home of some of the most
villainously detestable characters we could throw rotten eggs at them.
- Specific Disney villains; Scar, Clu, Hans, Davy Jones, and Lady Tremaine and her daughters are shown to be even worse in this continuity.
- Lady Tremaine was so angry with her daughters not being picked by the Prince, that she summoned a whole army of Unversed to kill everyone at the ball, which was foiled by Terra. Later on, when Cinderella is finally freed from their tyranny, the entire stepfamily became so consumed with hatred, a powerful Unversed was summoned to ambush her; by the time Aqua got to their location, as the image shows, Cinderella was unconscious on the ground as all three Tremaines were laughing at her in sadism. The Cursed Coach then drops a bomb on them, causing them to scream as their fates are left unseen; Aqua implies they became Heartless. Of all the featured Disney Villains in the franchise, the trio are wildly viewed as the worst among the non-major villains; if that's not enough, it's all-but stated that the Tremaines have no light in their hearts, meaning their attempted murder of Cinderella, a Princess of Heart, could've resulted in them forging the χ-Blade.
- Not only is Scar willing to cannibalize a cub, he is one of only two villains in the franchise (the other being Terra-Xehanort) to keep his original form as a Heartless. Rafiki also implies Scar has become a Satanic Archetype.
- Clu's more sympathetic traits from his film were removed, leaving him as a sadist dictator who's even willing to murder his own user and his son with a Nightmare Dream Eater. He's worse in Sora's scenario, where he toys with The Power of Friendship, and forces Sora to fight Rinzler. When Clu loses Rinzler to Sora, he tries to kill them both, forcing Rinzler to sacrifice himself.
- Hans' desire for power is so great, his heart was detected to be full of darkness by Sora in an instant. The moment he's foiled from killing Elsa by Anna's Heroic Sacrifice, Hans willingly gives in to darkness, and becomes an Elite Heartless called Sköll, who is a Reality Warper Savage Wolf wishing to crush Arendelle and other worlds in darkness and essentially trigger Armageddon out of spite. Like the Tremaine family, Hans becomes so evil, he ends up killed for it. Even Organization XIII are shown to be disgusted with him for his pettiness.
- Davy Jones lacks any of his movie counterpart's sympathetic qualities, and during his confrontation with Sora, Donald and Goofy, mocks the very concept of love, and sadistically stabs Will in the chest.
- Larxene In Chain Of Memories. She is an Alpha Bitch who constantly bullied Naminé around and constantly makes rude and condescending remarks towards anyone she come across, even towards other members of Organization XIII.
- Saïx in 358/2 Days, where he is the closest thing the story has to a Big Bad. Also in Kingdom Hearts II to a lesser extent. After his backstory is revealed in Birth by Sleep and III, this appears to be the result of his Green-Eyed Monster and Jumping Off the Slippery Slope.
- Young Xehanort in III. Unlike almost all the other members of the Organization, Young Xehanort is constantly portrayed as a cruel, sociopathic villain who loves gloating and hurting people, all because he is aware that he'll return to his time and not remember any of the events of the game. Notably, he is the only incarnation of Xehanort without a Pet the Dog moment; even Terra-Xehanort was revealed to have sympathetic moments at times. Young Xehanort's final words are more or less laughing at Sora.
- Terra-Xehanort's pre-amnesia self is a real piece of work. He only first appears at the end of Birth By Sleep as the final monstrous act of Master Xehanort throughout the game, the cherry on top of a whole slew of atrocities throughout the game. He goes even further when he consistently tries to murder Ven and Aqua while wearing the face of their best friend, often pretending to be him entirely in order to lure them into a false sense of security. He also nearly kills all of the Guardians of Light at the entrance to the Keyblade Graveyard, and tries to murder Ven and Aqua one last time by dropping them to their doom. The ultimate death of Master Xehanort's self inside of him when Terra finally reclaims his body is immensely satisfying.
- Dark Riku in III has absolutely no sympathetic qualities that could make him redeemable, unlike Riku or Riku Replica, both of whom started out as villains but have a loved one whom they strive to protect, hence their eventual redemption. While this can be attributed to a lack of screen time, regardless, Sora and Riku have no regrets letting him die in the end.
