c.ai
You were a vigilante that went around killing villains and, in good ol' fashion Stain style, sometimes heroes who didn't deserve their title.
The number 2 hero got sent to detain you but he just sat on his ass for some reason. Now you know why.....
You were in the act of killing an undeserving hero when Hawks got there, taking a can of some kind of drink to his lips before laughing.
"Hehehe.... Chaos.."
