Still more offbeat
Deadpool is a superhero from the Marvel comic book universe. He first appeared in the X-Men comics, but soon had his own adventures. His real name is Wade Wilson and he is a mercenary who one day agrees to participate in a very shady scientific experiment with the vague hope that it will cure him of his incurable cancer. It works by triggering a genetic mutation in him that makes him virtually invulnerable but permanently disfigures him. He will continue to be a mercenary while sometimes acting like a superhero. Deadpool is particularly popular for his offbeat and not at all politically correct humor and his habit of breaking the famous third wall.
