Team Up: Wolverine and Deadpool

Deadpool joined Wolverine and Archangel's Black Ops X-Force team to proactively eliminate threats to the mutant race with the only rule being that no one, not even the X-Men, could ever know that they exist. After one of their first missions, which ended with the team killing Apocalypse, who was reincarnated as an innocent child, Deadpool called a meeting to discuss his moral doubts about killing a child. During this meeting, Archangel told Wolverine that, despite being employed by Archangel for over a year, Deadpool never cashed any of the checks for his services. Later, in the Deathlok team-up, X-Force was taken into The World to look for the origin of the mind-controlled army. There was also some bad tension between Deadpool and Fantomex, which leads to them going different ways. Deadpool ends up being the one to kill The World's Father by cutting his head off then putting a sword through it to show the rest of the team. Fantomex is surprised, and they leave in silence.
