I'm not entirely sure what animal type you've based Keizer Ghidorah's body off. Too lanky to be a lion, so perhaps a cheetah? Nah, a guy like him seems more likely to use sheer power rather than speed. Longer front limbs than back limbs? I always thought that was a giraffe thing. But they're herbivores, and therefore not suited to kicking ass at all!
Not what I meant. They fight BACK when attacked. You're not gonna see a giraffe say/think 'Imma kick this guy's ass cuz I feel like it" and then go beat the crap out of somebody. Ghidorah's ALL ABOUT doing that.
