Deadpool Vol. 8: Operation Annihilation
Deadpool has become fixated on achieving the one thing that's always been beyond his reach: death. Not an easy thing for an unkillable man to achieve, but that's not gonna stop him from trying. But first, he must figure out the all-important question: how? What in the world can kill Deadpool? It has to be big. It has to be powerful beyond description. It has to be green? Plus: Macho Gomez is back! And this time, he's brought friends. HIS friends? Nope - Deadpool's friends. And every single one of them has an axe to grind with our boy Wade for how he's treated them in the past. No, really - they have axes! Collecting DEADPOOL (2008) #36-39.
