Ep. 51: Optimus Prime and Galvatron engage in a final battle on Cybertron for the fate of Jungle Planet.

51

On Cybertron, Optimus Prime questions Galvatron’s motivation, noting that Starscream’s encouragement was merely imaginary. While Autobots construct rocket engines to restore Jungle Planet, Galvatron sabotages the boosters and challenges Optimus to a duel in the command center. Former Decepticons, now freed from Galvatron’s control, assist the Autobots in this effort. The combatants inflict severe damage on each other, with Galvatron severing one of Optimus’s wings using an energy scimitar. Vector Prime’s ghost appears to Optimus, urging him not to lose and granting him the power of his sword. Utilizing the Matrix of Leadership, Optimus transforms into a golden mode resembling the planet leaders. The two leaders clash with swords until Optimus destroys Galvatron, who mutters his final words before disintegrating, marking his death.
