User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-5460283-20121202181839

I'm just going to float an idea out there about how Amatsu stays in the air. I think that he absorbs heliumand hydrogen from the air into something like an air sac. This would make him full of gasses that are lighter than air therefore keeping him aloft. And the storm that "follows" him is the biproduct of the helium and hydrogen leaving the atmosphere around the Amatsu.

Comment/Criticize/Agree I want to hear your thoughts on this.
