This was going to be my entry, but I got the character for free. Here's this anyway.
Name: (undecided, my little bro gets to pick) Species: Unknown Gender: (undecided) Job: Assassin Story: Worked for an unknown company to cause 'accidents' in their enemies' businesses. However, was assigned one day to kill a close childhood friend. Killed friend and still feels guilty. Guilt manifests as a shadow form that takes over body sometimes when emotions become too strong. Learned to bottle up feelings. That's it I guess.
