Hiya mate! 
Indeed.
I wonder if the Gargantuan size is meant to be open-ended?
Its also interesting to note that the Huge size is only 50% bigger than Large, while the Gargantuan size is only 33% bigger than Huge.
One thing I have been pondering is giving the atomic breath weapon an ability to drop a target to bloodied (or deal damage equal to its bloodied value)...possibly if Godzilla scores a critical hit with it.

Khisanth the Ancient said:Yeah, I suppose there is only so many ways it can be done - in some sense Godzilla is a fairly 'simple' monster (compared to a superintelligent god or sorta-god like Orcus, Galactus, Surtur). Also there've been enough movies that his abilities are pretty well defined.
Indeed.
One difference, though, is without the Mega size rules my Godzilla is stuck being "only" tarrasque sized. Big and scary enough for most purposes, but he should be about 160 feet tall (Showa) or 330 (Heisei).

Also, the 3.5 version you have is the Heisei Godzilla, while I just grabbed the powers I liked from all different versions (Supercharged Atomic Breath is from Godzilla: Final Wars, though sadly 4e doesn't allow for ranges of "into orbit", but otherwise he's more or less Showa Godzilla, minus the flying-on-his-own-atomic-breath power.)
