It depends if you count the character as having all powers given to him through outside means. If so, I'd say Light from Death Note.
Besides being brilliant, he can kill anyone with a name and a face, and thus basically anyone on the list.
By the way, Vash and Alucard aren't human... Vash is a "plant" and Alucard is a vampire. But whatever. What a silly, pointless topic.
