Part of III of my greater Complete Monster list, this one dealing with ones from Disney and Star Wars (both Disney continuity and Legends continuity). Given that Disney owns Star Wars now, I figured it made sense to group the two together for this list.
In-Progress
Beginning the Disney examples the worst manifestation of Xehanort other than Master Xehanort. A power mad maniac who corrupted Riku, ruined the real Ansem's reputation, and sought to plunge all the worlds into darkness...for basically no reason. And, the Heartless under him did manage to destroy several worlds. Granted, many of those worlds were brought back, but still.
The version from the Lone Ranger movie. Besides his being a cannibal (repeat offender at that), he also massacred the inhabitants of a Native American village AFTER they'd saved his and Latham Cole's lives. He's also in on Latham Cole's scheme that involves framing other Native Americans for killing Caucasians, causing those Native Americans in turn to get killed by US Cavalry. Oh, and he also kills a worker under him due to complaining about the dangerous working conditions.
And now for Disney's most infamous example of this. To start, he murders an innocent woman just because she's a gypsy, intended to murder her baby just because he thought it was ugly, and only takes him in because he's forced to. From there he's shown to be a cruel and abusive parental figure, enjoys torturing his own men for failure, seeks to wipe out gypsies, and is willing to murder innocent families while hunting for a woman he lusts after. He also tries to kill said woman multiple times, showing that he does not, in fact love her.
A sort of techno-Hitler who wipes out a species save for one survivor because he saw them as a threat to his trumped idea of "the perfect system", gets off on seeing other programs kill each-other in gladiatorial games, kills one of his own men for failing him, betrays and murders his ally Zuse, brainwashed Tron into his servant Rinzler, and when offered the chance to redeem himself by his creator...attacks him instead.
To sum it up he's pretty much responsible for almost EVERY BAD THING THAT HAPPENS IN THE ENTIRE SERIES
Though far from the only Disney villain who's tried to kill a child, what makes Scar's case of it particularly bad was that the kid in question was his own nephew, and it was immediately after his gleefully murdering his own brother. As king of the Pride Lands he turns it into a barren wasteland and doesn't care if all of his people starve to death due to being a narcissistic psycho. He is also shown to have no loyalty to anyone but himself, as shown with his being quite agreeable to selling the Hyenas out to save himself.
After being (understandably) rejected by his idol after pestering him too many times, Syndrome goes on to become a mass murderer of superheroes just so he can pretend to be one. When Mr. Incredible's family comes looking for him he gleefully and without remorse has their plane shot down even AFTER learning that there were children on board. When it's believed that the family is killed he mocks Mr. Incredible's loss and is shown to have no loyalty to his assistant Mirage, risking her life haphazardly. He also then tries to kidnap Jack-Jack and turn him into his protege just to spite Mr. Incredible.
Beginning the Star Wars examples with Aurra Sing. Yes, she has a Freudian Excuse. But so do Darth Bane and Darth Zannah, and it doesn't save them. Fact is, Aurra Sing is a sadistic and bloodthirsty bounty hunter and Jedi killer who keeps the lightsabers of the Jedi she's murdered as trophies. In the Clone Wars cartoon, she shoots an injured man begging for mercy in the face with a sadistic smile on her face, brutalizes prisoners for fun, goads a young Boba Fett into being more brutal than he is comfortable with, cares not for the young Clone cadets on the ship Boba sabotages despite their being children, murders her partner when he tries to walk out on her, and tries to assassinate Padme Amidala for Ziro the Hutt.
Possibly. It's not clear if he has a sympathetic backstory or not. Without it though, he's definitely this on the account of being the Galactus of the Star Wars universe, who is quite agreeable to devouring everything in the galaxy just to keep himself going.
The top CM in Star Wars. A pure evil sociopath and sadist who murdered his own family, murdered his master, started a galaxy-wide war that killed scores of people and spawned numerous villains (such as General Grievous), was responsible for countless atrocities in the Rise of the Empire Era and Rebellion Era, nearly wiped out the Jedi Order, corrupted a Jedi Knight and turned him into a monster (and took pride/pleasure in it), created a fascist empire that is xenophobic, pro-slavery, anti-cyborg, misogynistic, AND prone to large-scale atrocities, and ultimately having no concern for anyone but himself. And, it goes without saying, but he's a CM in both Star Wars continuities.
Subsequent appearances may give him redeeming qualities, but as of now, General Hux qualifies. Considering he was the one who had Starkiller Base destroy numerous planets in one fell swoop, including the capital of the New Republic (Hosnian Prime). Also, while Snoke was in on it, it was actually Hux's idea to use the weapon.
Though in the Clone Wars he was more of a Well-Intentioned Extremist, as of "A New Hope" he casually destroys an entire planet filled with innocent people for no other reason than to show that the Empire could.
A coward and a traitor who left Jaster Meerel to die and from there became a sadistic and heartless bounty hunter who would always bring in his victims dead even when they were worth more alive. He also tortures the nicest character in "Star Wars Bounty Hunter" to death and in a reckless attempt to kill Jango blew up a space station that had lord knows how many people on it, at which point Jango Fett's leaving him to die is VERY satisfying.
While he does balk at Malak's order to destroy Taris and even expresses Even Evil Has Standards, consider this: he earlier led the bombing/razing of another planet (Teloes), which killed millions and horribly devastated most of the planet. Later, when Darth Malak bombards Dantooine too, he taunts Revan, Bastila, and Carth about it (while also sadistically torturing them). So in other words, that he's already committed planet-level genocide once, and then taunts the heroes over his boss doing it, makes his earlier balking at it seem hypocritical. And if expressed moral standards just make a villain look like a hypocrite, then the standards are worthless.
Legends version. Besides the dozens of fellow podracers he murdered over the years with homicidal glee and his also being an unrepentant cheater, Sebulba also had a double life as a slave-trader, child slaves to be exact.
Essentially the same character as Palpatine and having similar atrocities to his resume. Notably his destruction of Nathema was done in such a way that even OTHER SITH are appalled by it.
The playable one, if you go full-on Dark Side
While in most of his appearances he seems to be just one many Separatist slimeballs, he attains Complete Monster status in the first season of the Clone Wars show when he orders his droid fighters to bomb and destroy "every twi'lek village within range" and to start with the inhabited ones first. From that alone you could imagine he'd rack up a pretty high bodycount, including women and children, so with that in mind I feel pretty confident listing him as this. Also, in the unfinished but canon episodes of the Clone Wars cartoon, we see that he's also been performing (with sadistic pleasure), unethical/fatal weapons tests on the natives of a planet the Separatists have seized, and also held the Clone Trooper Echo prisoner against his will, using him in his experiments and keeping him only barely alive.
