Ultra Metal Sonic and Super Sonic 4 clash in a titanic battle, where Sonic blocks a punch but the kinetic energy blows out ten million galaxies behind him. Super Sonic 4 then takes a nearby blackhole and sucks it up, blowing it back out Ultra Metal Sonic. He's beaned by God Tails/Cream who converts his face into Supermatter, and then takes a baseball bat- with a rusty nail in it- and strikes Sonic's head so impossibly hard, I can't even describe it anymore. It breaks apart all of reality and all of superreality and all of everything. Everything cracks up and breaks apart and explodes, it's clobbering time!
