HEAD TRIP, Part 1 of 6 It's the Merc with two mouths! Deadpool travels to the Savage Land to retrieve the severed-but-still-hungry head of the Marvel Zombies Deadpool! Now, Deadpool must dodge Hydra operatives, dinosaurs, and zombie cavemen as he attempts to take his not-so-precious cargo back where it came from: the Marvel Zombies Universe.

HEAD TRIP Part, 2 of 6 Crash-landing in the Savage Land, Deadpool finds himself face-to-face with his own Zombiefied head! To make matters worse, the nasty little critter went ahead and bit a few of the locals, so Deadpool has to put the smackdown on some zombie cavemen if he's going to have any chance at escaping and completing his mission.

HEAD TRIP Part, 3 of 6 Trapped between cavemen zombies and an elite Hydra strike team, Deadpool's only bargaining chip is the thing they both covet: The severed-but-still-devious head of the Marvel Zombies Deadpool! If the Merc With a Mouth is going to survive, he's going to need a timely assist from a guy in a loincloth named Ka-Zar and his saber-tooth sidekick.

HEAD TRIP Part, 4 of 6 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.

HEAD TRIP, Part 5 of 6 After Dodging Dinos, cavemen, and a particularly nasty Zombie T-Rex, our intrepid trio—Deadpool, Dr. Betty and "Headpool" a.k.a. the severed head of Zombie Deadpool—escape in an >ahem< borrowed Hydra shuttle and head for the A.I.M. space station to deliver their hot bio-cargo.

HEAD TRIP, Part 6 of 6 Space, the Final Frontier. O-ver-ra-ted. Wade, the severed Zombie Deadpool head and Dr. Betty find themselves back on good old Earth, knee-deep in swampy goodness. Everyone agrees the zombie virus should be put safely back into its own dimension. All they've got to do is find that damn dimensional portal.

What do you do with a homesick zombie head? Take it back to the zombie universe, of course! Hopping through an interdimensional portal in the Florida swamp with Headpool tucked under his arm, Deadpool soon finds himself bouncing through a series of outlandish alternate realities, each more warped than the last.

Deadpool and Headpool head to the Zombieverse! You heard right. With the luscious Dr. Betty and the hapless Bill agent of A.I.M in tow, Wade dodges starving zombies who are hungry for their pound of flesh...and hooks up with very possibly the last stronghold of human life on the planet and its fearless leader: a sexy Ph.D. who's mighty handy with a missile launcher.

Bloodthirsty zombies and interdimensional travel have got Deadpool feeling a little, well, frisky. But there's only one way that Wade can earn the affection of the luscious duo of Dr. Betty and Professor Veronica: by capturing one of those pesky zombified super heroes for a little experiment. And just where does a can of "stink spray" fit into his plan?

Can Deadpool and pals find their way back through the Nexus of All Whatchacall to their home dimension?
