Deadpool: Merc with a Mouth (2009) #4

"HEAD TRIP," PART 4 Things just keep getting more savage in the Savage Land for poor old Wade. Not only does a crack squad of Hydra shock troops want to put the smackdown on our boy Deadpool, but the cavemen want back their god (i.e. the severed-but-still annoying head of the Marvel Zombies Deadpool) and have turned out the troops, spears ready to fly. Even with Ka-Zar's help, it's going to be a close one. To make matters worse, "Severed Headpool" can't keep his teeth to himself. One hungry bite can bring a world of hurt down on top of Deadpool and the luscious Dr. Betty. Parental Advisory ...$2.99
