It's the Merc with two mouths. Deadpool travels to the Savage Land to retrieve what might be the deadliest bio-weapon the universe has ever seen. What is this deadly object? When the secret is finally revealed, it's enough to throw even the Merc with two Mouths for a loop. To save the universe, Deadpool must team up with his Zombie counterpart himself to dodge Hydra operatives, dinosaurs, cavemen and zombie cavemen as he attempts to take his not-so-precious cargo back where it came from: the Marvel Zombies Universe. Issue #1 also includes a reprinting of the first appearance of Deadpool from New Mutants #98.
