He dies at the end.
**SPOILER ALERT**
Don't say that. Zilla always comes back. Fuck Superman, Rocky, and all of your other comic book shits. You can't kill him. The best you can get is to chase him back into the sea and pick up the pieces.
Fake trailer
So far I've spotted -
Pacific Rim
Godzilla
2012
Transformers
Battleship
Cloverfield
Skyline
I might've missed one or two, it's a nice effort, but anyone with half a brain can see its a polished fake.
