Here's a test I did of Godzilla. I tried doing the atomic breath with Photoshop but that crap takes forever. Best thing to do is get After Effects.

Here we've got Godzilla 2000 roaming around all proud n' whatnot, when the new, 2014 Godzilla appears. Intimidated, G 2000 starts a friendly competition with a little atomic breath show of strength. Little does he know, G 2014's atomic breath is a bit more so (not like the actual film but you get the idea).

Thanks to SuperFredrikNilsson and AlexTriceratops123 for their awesome sound effects.
