They will have all the prank wars. He's not really family oriented either. His mother died when he was five, and then his drunk/abusive father came back from the military. I originally was going to have Adrian snap, and kill his father, but instead made him join the military fresh out of high school. He's got a mad case of PTSD from his life ventures.
I want Adrian to have like a weird phobia because I know Deadpool is supposed to be deathly scared of cows/cattle. I just think it's amusing. This guy, who can't die is scare of a fuckin' cow. He doesn't smoke, so that's all good.
Oh, and on missions, be prepared for singing, and dancing because that's how serious he takes life and his job. He fancies 90's music, like obsessed pretty much.
