If this is still open:

Codename: ZomGuy
Age: physically 21
Personality: the being known as ZombGuy is devoid of all positive emotions, and is thus always in a negative mood of thinking, speaking, and feeling. He is incapable of feeling connected to other people or animals, but that does not mean he could re-learn how to feel someday.
Ability/power/s:
1) Undead- He cannot die. ZombGuy is incapable of the sweet release of death, even if his body is completely vaporized, he will exist in a corpeal form
2) limited mind control- through physical contact, he can control those he comes into contact with, though only forcing them to do the most basic of movements
3) Deadly Proximity- if he says in one place for more than a few minutes, the surrounding landscape will begin to die, though not affecting people or animals
Weakness:
1) Sunlight/Heat- When exposed to any source of heat or daylight, he will be sapped of strength and strength over a progressive amount of time
2) lead- when attacked by a lead substance, it feels like acidic burning sensation, though does not affect him physically (more a mental block)
(Background? Arch nemesis? Crush? Weapons? Gadgets? Anything else you want to add?)
Arch nemesis- none
Weapons- Just his undead hands and teeth, but he can use whatever he can to kill
(Why should my character choose yours? 50-150 word limit.)
I looked at the roster and there doesn't seem to be a zombie type character. Also, everyone else seems human enough to feel emotions, it would be interesting to throw in a character who can't (for now) feel such things, but being essentially a zombie he might be too cliche, so I'd understand if he is denied.
