In "Chain of Command", Ultra Magnus constantly criticizes Wheeljack's actions, such as attacking without orders, and bringing Miko along. It is revealed that Ultra Magnus becoming the leader of the Wreckers was the reason that Wheeljack deserted. When fighting Predaking in the mine and losing, Magnus once again criticizes Wheeljack for detonating a grenade in a confined space. Ultimately Wheeljack deserts the Wreckers once again, though he returns to the Autobot base back in Nevada. This is shown in the episode "Plus One", in which Ultra Magnus, Bulkhead, and Miko return to Nevada in Magnus' ship instead of by groundbridge, bringing with them the reclaimed Apex Armor.
