Megatron-optimus Prime Face off

Prime transforms into a fire engine, and can convert into a secondary flight mode, or merge with his trailer into Super Mode. Later using the matrix of leadership replacing the role of the combination spark, he combines with his fellow Autobot Leobreaker to form Savage Claw Mode (Liger Convoy) , and with Wing Saber to from Sonic Wing Mode (Sonic Convoy) though the autobots claim when prime and leobraker combine for the first time, " i didn't know autobots could do that:.. Whether he or Galvatron are the stronger, or if both are in perfect balance is unknown, as although Prime did ultimately destroy Galvatron in one final blow, it was with Vector Prime's sword, given to him in the last few seconds before they clashed for the last time. His Cyber Key Power makes his cannons more powerful ("Galaxy Cannon: Full Burst!). As Liger Convoy, his Force Chip special attack was Liger Grand Break; as Sonic Convoy, it was Sonic Double Impact.

Megatron is a triple changer, transforming from a Batmobile-like dragster into a Cybertronian jet. He can project devastating electrical blastst from his hands, and his Cyber Key activates many powers, including vehicle-mode thrusters, a claw shield (Death Claw) and his deadly "Death Machine Gun," (Death Machine Gun) with which he fatally injured Hot Shot, Red Alert and Scattorshot. He could also combine with Nemesis Breaker to form Dark Claw Mode (Liger Megatron) for a short period of time, with a similar Cyber Key power to Optimus Prime's Savage Claw Mode Cyber Key attack (Liger Death Strike).
As Galvatron, he retained all his previous attacks, could project dark energy, and shape it into a sword. In his final battle with Optimus Prime, he gained a new transformation in which his back wings/cape formed a cannon on his chest, which fired dark electrical energy (Death Cannon). His armor can also restore him.

With these, all Optimus can do is to use his wits and skill to defeat the evil megatron.
