Boss: Rez
Attack Style: Rez gathers planets from across different galaxies, planes, and alternate universes. If provoked to attack, Rez will crush planets in his jaws until he destroys a world where the player has once existed. If the player's parallel planet is destroyed, they will immediately fade from existence - so it's a race against the clock to chip away at Rez's HP before he finds one of your planets.
