In another alternate reality, all the heroes turned into zombies and ate all of existence. Then ate Galactus, gained his powers, and tried to hop into another universe for more munchies.
Marvel spider-man succeeded and entered said reality, but also remained "himself" and tried to cure his zombieness. But while out and about he ran into the sinister six.
Zombieness took over, and he ate and turned 5 of them, leaving sandman to escape.
While running away Sandman ran into his realities spider-man, and went into a fit of rage and killed him. (thank God Sandman isn't a serious villain).
Kinda sucks because later the newly zombied Doc Ock bites Mary-Jane's head off.
If it makes you feel any better the Zombie spider-man eventually succeeds in creating an "antidote" that permanently kills zombies, with the help of sandman.
