How often do you think Godzilla used his Atomic Breath in the movie?

Maybe once or twice i think but as alot of other people have said when his back is against the wall but who knows im not a phsycic lol the wait for this freaking movie is killing me!!!

I think he will use it near the end of the movie, when he fights the muto...

To be honest, I think he uses it once. And I reckon he will use it in the final fight against the last MUTO. The reason why he uses it only once is because he first needs to build up on his atomic energy by feeding on nuclear reactors and power plants in order to finally shoot out his atomic breathe. That is my guess.

When ever he needs to.

I would guess when Godzilla will fight 8-Legged Muto.

The smallest known muto is "Hokmuto" as well.He`s really small compared to some buildings and godzilla`s leg.

8-Legged muto,Has almost the same size as Godzilla.
