arrives on Earth in "Scattered" and meets with Arcee and Jack. Like Wheeljack, he has his own personal vessel, though he is a good deal larger. In "Prey," Ultra Magnus tells Jack and Arcee that he detected five Autobot life signatures that remained online. Ultra Magnus also mentioned that he had encountered other Autobots during his travels, many of which perished in Decepticon attacks. Later, he helps Bulkhead, Wheeljack and Miko escape from the Predacon named Predaking before finding Ratchet, Bumblebee, and Raf at the Harbinger and meeting Agent Fowler and June Darby. Ultra Magnus decides that the Autobots must defeat Megatron once and for all and, after taking command, offers them a large supply of weapons to assist in the fight. In "Rebellion", Ultra Magnus leads the assault on Darkmount, where Predaking is sent through a Ground Bridge into the Antarctic. Magnus goes after Megatron but is defeated. Before the Autobots can be executed, a recently repaired Optimus Prime arrives and destroys Darkmount. Later, Magnus gives Optimus command over the Autobots again. In "Project Predacon", Ultra Magnus' vehicle form is revealed, a nearly all-blue version of Optimus' semi-truck form. It is also revealed that he had been put in charge of the Wreckers back on Cybertron during the war, as he felt there needed to be someone to keep them in order. Once again taking charge of the Wreckers on Earth, Ultra Magnus also takes the Forge of Solus Prime as a new weapon, as it had no more power and he wanted to give it a "practical use". 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 ground bridge, bringing with them the reclaimed Apex Armor. In "Evolution", Ultra Magnus begins to realize that the Autobots aren't very welcoming towards him, not just Wheeljack. He turns to Optimus, the only one who doesn't treat him the same way,
