"Ultimate Energy Combiner: Omega Prime!"
Due to the greed of his brother Ultra Magnus, Optimus Prime was forced into a combination with him. 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, arguably the most powerful "Prime" in existence, as he has easily defeated the entire opposing Predacon troop on his own on multiple occasions. Essentially, he is, in other words, a one-man army whose might can make short work of anything.

During a fight with Megatron, Scourge, and the Decepticons' Commando subgroup, Optimus was ganged up on by all seven at once, and they were close to nearly destroying him after they set off the oil in the island of Sector K to ignite in the midst of their firepower. Ultra Magnus showed after having followed Sky-Byte via a hidden tracking device the Pred secretly planted on Prime's back just before the Autobot leader went through the Space Bridge for Sector K. 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 themselves both into combining. What he didn't expect, though, was that Optimus had as much control over their new body as Ultra Magnus did. His plan to steal the power of the Matrix backfired and he had to cooperate with Prime to defeat the enemy.
Omega Prime would later wield the Matrix Blade in the final battle against Galvatron.
Once again, Optimus and Magnus would team up to become Omega Prime. When the twins were abducted by the Chaos Bringer and pitted against his minions, the two combined into Omega Prime in order to fight off the Planet Eater's forces. The fight ended early, as Unicron's physical form was destroyed in another universe, resulting in a gigantic black hole that threatened to unravel the very fabric of existence. He later stopped Nemesis Prime from using the Dead Matrix to revive Unicron and destroy Primus with his boot of justice.
