Ep. 52: Metabee sacrifices himself to defeat Babby-Blue, leading to Meta-Evil's redemption and Brandon's alien reveal.

Doctor Meta-Evil deploys the colossal Medabot Babby-Blue, forcing Doctor Aki to pilot a Giant Metabee. Metabee lacks the power to move it alone, so Brass, Peppercat, Neutranurse, Sumilidon, Totalizer, Kantaroth, and Cyandog board to help. Despite their combined efforts and a Medaforce blast that shatters Babby-Blue's forcefield, they cannot damage the enemy. Metabee ejects his companions, bids Ikki farewell, and crashes the Giant Metabee into Babby-Blue, destroying both. Meta-Evil survives but is confronted by Brandon, who stops the violence. Professor Hushi arrives in a spaceship, explaining that ancient Medalorions were wiped out by constant battling. Meta-Evil's cat, controlled by Medalorion Miko, reveals Medabots no longer wish to rule the world. Meta-Evil accepts Hushi's offer to explore space, leaving Doctor Aki as Medabot guardian. Metabee is reborn, and Brandon sheds his human skin to reveal he is an alien. They depart, leaving Victor to robattle for honor with Warbandit armor.
