#1: DOCTOR HARLAN FONTAINE (La Noire):
Fontaine is one of the most cold and ruthless characters in the game, obsessed with power and manipulation. He constantly utilizes people to further his ends, as seen द्वारा his keeping Elsa Lichtmann addicted to drugs in order to investigate the breakdown of an addict and using Lou Buchwalter for the Fund, causing his death. He is also a master at manipulating people, demonstrated द्वारा how he convinced Courtney Sheldon to give him the stolen army surplus morphine in blatant abuse of his trust. Furthermore, he manipulated Ira Hogeboom to assist in the Fund's nefarious plans.
And when Sheldon confronted Harlan about the Suburban Redevelopment Fund, Fontaine easily played on Sheldon's trust. Tricking him into thinking he was innocent, and using the opportunity to inject and overdose Sheldon with morphine, killing him (and after all they been though)..


#2: HANNIBAL LECTOR:
Lecter is possibly the most intelligent human alive, possessing an intellect that cannot accurately be gauged द्वारा any test known to man. He is an expert in psychology (though he does not believe it to be a science) and is able to frighten, manipulate, and bend others to his will with mere words. He is also able to use his immense presence and commanding but subtle personality to great effect..

#5: PINKAMENA: (Cupcakes):
कपकेक is a very, very dark parody of MLP.
Pinkamena is a evil version of sweet Pinkie Pie.
She is an evil genus, secretly turning people into कपकेक द्वारा using a room that's something out of TEXAS CHAINSAW MASSACRE. In the orginal story she horribly murders Dash, and it's clear she's been doing this for a LONG time.
She's become one of the most famish internet villains of MLP. I myself use her in a lot of things. Including a parody series of GRAND THEFT AUTO. In witch she's Trevor's closest friend, and it's HIM who made her this way, he watches her muder, steal, and eat people.. And only becomes और and और proud of his little "pet"..

He was also the reason why Anakin became Vader and pretty much set the entire plot in motion..


#7: PENNYWISE THE CLOWN:
Unlike many horror monsters before him, Pennywise the Dancing Clown was never against killing children. In fact, he actually preferred to kill children as they were an easier target. That was probably why he chose the form of a clown, a figure that both entertained and terrified many young children. It had razor sharp teeth that he could use to kill people..


#8: FRIEZA (Dragon Ball Z):
Frieza is a polite, yet an extremely sadistic individual, taking great delight in slaughtering and destroying others, particularly on a massive scale. This is best shown when he laughed in delight as he watched Planet Vegeta blow up from his Death Ball. Frieza also enjoys making people suffer before killing them, which is why he does not kill his foes outright. A notable fact is that he has tortured every character to fight him..


#9: XERXES (300):
This depiction of Xerxes is portrayed as a power crazed, overconfident, and megalomaniacal psychopath, incredibly determined to conquer the known Persian world.
