Sylar

Sylar is a superhuman with the ability of Immortality, electricity, telekinisis, every power in the world he possesses, he is the hardest to kill villain of all time, because he has been killed in every single series of Heroes, but he still manages to come back every series. He can officially not-be-killed by anyone and he could easily kill Freddy Krueger.

The Start
His name was Gabriel Sylar Gray and was a watch maker, until one day a girl, named Elle Bishop (who was working for an organisation who monitors and finds people with powers) arrived at his house to find out his powers. She showed him her electricity and he showed her his telekinis, but one day H.R.G told her to make him feel jealous so she arrived at Sylar's house with another guy who has the ability to shoot bullets from his fingers, and she called him 'special' this made Sylar angry and he killed him by using his ability of telekinisis to cut open his skull. Elle fled to the truck and drove away saying that "you turned him into a monster". And that was the start of Sylar.

He went on a 'hunger' rampage and started killing people with powers, taking their abilities and using their powers, he did it again and again and again and has one of the highest body counts of any serial killer. he killed many, by the end of series 1, but in series 2 he killed even more and gained the ability of Immortality, he did it again and gained so many abilities by the end of series 3, and then series 4 he was brainwashed by another superhuman, who was told by Angela petrelli (who has the power of De ja vu) to overide his ability of shape-shifting, making him think that he's Nathan Petrelli(he had power of flight, and was killed by Sylar), and now he's not a pycho-killer anymore, but he is aware of his powers.
