Marvel Comics - Deadpool Vol 3 - X marks the spot
Collects Deadpool (2008) #13-18.
Deadpool wants to be an X-Man. And he's not going to let anyone stand in his way - not even the X-Men! So when the father of the mutant Mercury lies to the press by telling them his daughter is being held captive on Utopia, Deadpool decides he can finally make the X-Men love him - really, really love him - by assassinating Mercury's father. Will Wade succeed and single-handedly set back mutant/human relations 50 years? Will he ever become an X-Man? Will he finally get some play from that smoking-hot chick with the guns and the Dalmatian spot over her eye?
