Galactus is a busy man. When he's not eating planets, or being a douchebag, he makes appearances frustrating the shit out of gamers, most recently in Marvel vs. Capcom 3.
He appears, talks a whole lot of mess, creates Cosmic infused clones of Marvel and Capcom villains, then takes off, presumably to feed his cat. After you're done with the clones, who happen to have the ability to consistently double team you, Galactus returns and casually laces you with 185 hits of finger lasers, before he hammer-fists, and subsequently KOs the Earth. Good times!
The encounter looks like a stressful affair for sure, but taking on Balrog, Vega, Sagat, and M. Bison at 8 stars was no cakewalk either. Totally ready for Galactus and his cheap tactics.
