51

On Cybertron, Optimus can't help but wonder. Galvatron was encouraged by Starscream to continue fighting, (although Starscream was in his imagination). The Autobots built rocket engines to move Jungle Planet back to where it was. Galvatron damaged the rocket boosters, and then challenged Optimus Prime in the command center to a final battle. The Autobots attempted to salvage the situation, along with the remaining Decepticons (after they were free from Galvatron) who arrived to lend them a hand. Meanwhile, both Optimus Prime and Galvatron were ravaged from each other's attacks. Galvatron uses an energy scimitar to cut down one of Optimus Prime's wings, causing serious damage. The ghost of Vector Prime appears before Optimus Prime and urged him not to lose this battle, also lending him the power of his own sword. Using the matrix of leadership, Optimus powers up into a golden mode similar to that of the planet leaders. Optimus Prime and Galvatron battle it out, using their swords. Optimus Prime uses the sword to destroy Galvatron. Galvatron mumbled his last words before he disintegrated, signaling his death. (Source: Wikipedia)
