In terms of looks, I really like the way G'14 did it. GMK is a close second.

I like them all but I think I have to say G14 and it wins by a 1% to the Heisei but it goes back to the original atomic breath that was more or less hairspray mist due to the time period of special effects. G14 is still " misty " but yet reinvented and more focused. It reminds me of the original alot and it's like "Oh hey there , I finally get to see what it would look like in the original if it was a colored version back then! "

i preferd the gmk vercion but g14 is stil good and i my 2nd favorite
Evacuate?, Godzilla is just a Legend!-Woman in GMK

Heisei through Millennium series. Those were the awesome Atomic Breath's. Especially the Spiral Atomic Breath.
\"SKREEONGK!\" -Godzilla

my favorite was G vs Destroyah, I liked the red with some lightning coming out, personally

Probably Godzilla 2014's beam is my favourite. Although I really love the beam from GMK and Godzilla vs Destroyah.

Mine was GMK because his actually looks like something that's an "Atomic" beam while almost every other breath from the other Godzillas would just look like fire or lazer.
