Armor of Unicron

Megatron has always sought power at every turn, and this is one of the most striking examples of success. After escaping from the collapsing Energon Sun created to contain Unicron's spark, he had stolen most of what remained of the chaos-bringer's power, and his body had been rebuilt with salvaged pieces of the destroyer's armor. The armor made Megatron very powerful, slowly increasing his power level over time, and was capable of healing him much faster than typical self-repair systems. It is presumably what generated his Cyber Key, and following Starscream's theft of the Omega Lock picked up on stray power emitting from the lock to unlock a new Cyber Key weapon, the Death Machine Gun. Revelation The was also capable of such feats as sustaining Megatron's spark and shape in a noncorporeal "ghost" form when he was destroyed, and absorbing energy to regenerate his body. It also allowed him to remotely tap the power of Gigantion's [Cyber Planet Key]] to become Galvatron one again. The armor's power, along with Galvatron's own, would be pitted against the full power of Optimus Prime in a final battle. Galvatron had the advantage, but when Optimus Prime combined his own power with that of Vector Prime's sword Rhisling and the Matrix of Leadership the Armor of Unicron was overcome at last. Galvatron perished, this time for good.
