Zilla or American Godzilla was featured it the U.S. remake of Godzilla. All that this monster is, is a mutated giant Iguana, that's it. Some feel that this monster was so disappointing, that he didn't even deserve the title Godzilla. So Toho renamed the monster Zilla. Plus he was featured in Godzilla Final Wars, getting disintegrated in seconds by the real Godzilla. He's not that awful of a monster. He looks kind of cool actually. You'll see worse soon.

I guess next time we make a U.S. design of Godzilla, we should use some creativity.
