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. As Hydra calls in a battle frigate to cause a little trouble, Deadpool comes to the sudden realization that a zombie virus unleashed on the world might be, well, a bad idea, and devises an ingenious plan to sneak off with the head.
