(The Marvel Zombies Universe:)
(After defeating Galactus using a machine that used their cosmic powers, derived from an eaten Silver Surfer, and encountering a Fantastic Four from an alternate universe, the Super Zombies realised that they could use their powers in ways they didn`t even expect, and starting to get hungry, the Zombie Giant Man created a machine to focus all of their powers into universal rips that they could use to travel to multiple earths....
Using this ability they made the jump to a different earth than theirs, but they had lost their cosmic power. This earth seemed to be lush in vegetation, and people. The Zombies soon started devouring anyone that came across their path, and slowly made their way to what seemed as a village...
Zom.Spider-Man: I wonder if there`s any food up there.
Zom.Wolverine: There better be cause
Im gettin hungry!
Soon several different villages were getting furious over the massive dissapearances of their Ninjas. Among these were the Hidden Leaf Village, and the Sand village. The Super Zombies eventually arrived at the Hidden Leaf Village, with other villages`s spies watching them...
They start attacking citizens, and soon the village`s Ninjas come to protect it. At the time only the Chunin, few Jonin, and certain other Ninjas arrive first.
Naruto: Who are these guys, and why are they eating people!
Kakashi: Be cautious everyone, keep your distance until we can gauge their strength!
Zom.Giant Man: Time to feast!
After having to kill, and seeing the very few people that have already turned into zombies, even his former trainer Iruka, he gets very angry, and lets it explode! He soon transforms into his Nine-Tailed Fox form, and spearheads the assault on the zombies.
Zombies can transform other people.)
