Ultra Magnus, who just joined the Prime team, had replaced Optimus Prime before Optimus returned.

Maybe because of his overly strict leadership style, he was slightly underestimated by the other bots, before he went on a mission with Optimus, Arcee, Bulkhead, Bumblebee and Wheeljack.

He fought alongside Wheeljack, dying against Predaking, until his right arm was completely destroyed, and he was forced to retreat.

Arriving at Hangar E, Ultra Magnus lay weakly on the Medbay, while Ratchet repaired his hand. Wheeljack: "Ultra magnus is like a wrecker when he fights" All was quiet after Wheeljack spoke.
