Loonatics: Unleashed Sezon 1 Odcinek 12: Acmegeddon (1)

Four villains who have battled the Loonatics in the past (Massive, Sypher, Weather Vane and Mallory Mastermind) miraculously escape during a prison transfer right under Duck's nose. They're transferred to a planetoid in space where they meet their liberator Optimatus (last seen in "The Comet Cometh"). He has major plans for them, and they're sent back to incapacitate the Loonatics. While Duck and Rev are out searching for the escaped super villains, the others are called to the scene of a crisis which turns out to be a trap. They're locked up in an underground prison. Duck and Rev return empty handed to HQ, and Zadavia informs them that they are the their missing comrades' only hope for rescue. Duck and Rev ultimately free their teammates and a big battle ensues with the super villains.
