The Department of Hotness arrive at the Regular Show-verse only for them to notice that it has already been invaded by the Guild of Super Evil. On an unrelated story, Hottie decided to keep her Core Drill on a keychain inside her pocket instead of hang it around her neck as it clashed with her flaming H necklace. The Park has been occupied by a horde of Trashtors led by The Warlock (last seen in the episode "Fortune Cookie"). After our heroes fight off the Trashtors, The Warlock grows gigantic and, with his magic fanny pack, not only tries to suck up The Park but the entire world. Gurren Lagann then combines with the Arc-Gurren to form the Arc-Gurren Lagann. Grapearl Lagann goes inside the Arc-Variblune and combines with Arc-Gurren Lagann to form Goren Arc-Gurren Lagann. The two then duke it out in an epic battle. Outmatched, The Warlock goes into outer space and grows into the size of the moon. That doesn't stop Goren Arc-Gurren Lagann or it's co-pilots as they merge with the Super Galaxy Dai-Gurren to form "Super Galaxy Grapearl Lagann", which resembles a gold-colored Super Galaxy Gurren Lagann. After the epic battle on a planetary scale, The Warlock is outmatched and beaten as he teleports away. "OOOHHHHHHH!!!" says Mordecai and Rigby inside the moon-sized super robot after yet another victory of the Dept. of Hotness. To be continued....
