Although today he enjoys favored status as a beloved member of the WWE Hall of Fame, "Rowdy" Roddy Piper began his WWE career as one of the most-hated villains ever to step between the ropes. After making his bones in the NWA during the late '70s, the Hot Rod came to WWE in 1984, where he quickly rose to astronomical heights. His battles with Hulk Hogan became a WWE mainstay, and the two often engaged in heated banter during interview segments that rank among the most-entertaining interview segments in the company’s history.

Big G's signature weapon is his "nuclear breath" which has been displayed as having power similar to an atomic bomb. This is amplified at the end of Final Wars by absorbing Ozaki's energy to fight King Ghidorah. Due to his need to consume radiation, Godzilla also naturally emits radioactive evergy. This means just being around him is dangerous, even if he doesn't touch you.
Another ability shown throughout the film (and other movies), is 'Zilla's ability to resist injury. Not only is his hide very thick, but he can heal at very rapid rates. He can also freely roam in and out of water for days at a time.
If he has any weakness at all, it's that Godzilla feeds off radiation, and thus can be lured to it much like an animal will seek out food. But give that Godzilla is also one of the deadliest natural disasters, this may not be an effective tactic in the end.
