Deadpool

Wade Wilson, aka the assassin Deadpool, takes a swing at being a hero--joining the X-Men, teaming up with Captain America and Spider-Man, and any other "do-gooding" he can get into. But not every superhero is eager to have the "Merc with a Mouth" at their side and, for that matter, not every superhero he fights beside is actually who he or she appears to be.
