Nigel Benn. He literally wanted to kill you in the ring and would proceed to **** on your grave afterwards. Despite being an actual alright bloke.
Yes. He's not a good boxer, but he's mean as hell. Seems to not only enjoy beating up opponents, but also pulling out every dirty trick in the book on them. He strikes me as the type of guy who would kick you in the nuts and then laugh in your face about it.
