Name/Nickname: Sylar A.K.A. Gabriel Gray.
User ID: KatanokiChaos
Fandom: Heroes; added in a few things that aren't exactly canon but seem to be viable considering past fights.

Gender: Male
Human: Yes, albeit an offshoot species from 'normal' humans.
Description: Dark black hair and dark brown eyes; lots of stubble, lanky, evil. Not a physical descriptor, but definitely the right word here.
Sylar:

When he was still known as Gabriel:

Personality
The (currently) main villain of the series Heroes, Sylar is, at the surface, a cold hearted serial killer without mercy (such as when he attacked Molly Walker, a child). However, the killing is all for a purpose--to fulfill his deep seated desire to be special. "The watchmaker's son... became a watchmaker," he said, speaking of his longing for a new name, a new life, and a new purpose--and the futility of his life, then, as Gabriel Gray.
Weapons:

• All: His powers. A current list is kept here. As of last Character Sheet Update:
  Telekinesis, Cryokinesis (<3!), Enhanced Memory, Liquefaction, Enhanced Hearing, Precognition and Induced Radioactivity.
• Non-Fantasy Settings: Higher intelligence but lower physical strength. Good with computers and complex systems. Programming and hacking/cracking possible strengths? Also, ranging, whether bow and arrow or with guns. Might keep a blade on him, but he'll hardly ever use it unless absolutely necessary.

Weaknesses:
His mother.
People calling him Gabriel instead of Sylar, other than those close to him (his mother).
Silly little men with katanas. -.-
Being caught by surprise. Always seems to happen to him. -_-
Not having time to think things out, possibly, since his strengths lie in his intellect. Albeit, he still does well in a fight.
Melee fighting. He needs to keep his distance.

Note: He seems to always keep his distance when in a fight; that's the reason for the ranged weapons in non-fantasy. If this changes(we're only in first season so it has high probability), I will modify.
