Animated Continuity
During a fight with Megatron, Optimus was ganged up on by several Predacons who nearly destroyed him. Ultra Magnus showed after having followed Sky-Byte via a hidded tracking device. Once he saw his brother could not fight back, he immediately merged with him in a forced combination. What he didn't expect, though, was that Optimus had as much control over their new body as UM did. His plan to steal the power of the Matrix backfired and he had to cooperate with Prime to defeat the Predacons.
