Gotta say if not for shrinking, I'd have to be a giga giantess/goddess. The thought of being able to wipe out whole continents by just rubbing up against the Earth makes me hot.
I made an account just to say this- Did anyone else notice the Tycho Monolith from "2001: A Space Odyssey"? (It's the black slab on the moon) If the name didn't give it away, I like Science Fiction. Giant(ess) and shrinking included, of course.
