Hands down the US
Godzilla 1985 credits, even if the movie logo shown doesn't exactly match up with the way the slash marks formed the words.
"Godzilla" continually flashing on the screen over explosions in
Godzilla vs. Mechagodzilla is pretty nice too.
The
Godzilla '54 credits are appropriately somber.
...oh, and the
Godzilla Final Wars credits are cool too, manages to hold you over with Godzilla 'cause he doesn't appear again untill an hour in.
