Omega Prime
- Omega Prime is an Autobot in the Robots in Disguise continuity family.

Due to the greed of Ultra Magnus, Optimus Prime was forced into a combination with his brother. Ultra Magnus merely wanted the power of the Matrix of Leadership for himself, thinking that a combination would let him access that power. The result of their combination is Omega Prime, arguable the most powerful character to ever bear the name "Prime", as has easily defeated the entire antagonist cast in Robots in Disguise on his own on multiple times.

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. Feigning compassion and understanding his brother's heavy burden in carrying the Matrix, Ultra Magnus pretended to offer Prime his helping hand, only to seize it and force the two of them to combine. 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. Forced Fusion
