Decepticon Empire

Although it was his ultimate goal, Megatron would never have been content with merely ruling Cybertron. The Decepticons are the highest form of life in existence, conquerers who will bring order to a galaxy plagued by disorder and weak organics. Thus, Megatron is destined to lead the Decepticon Empire to rule the universe. He will accept nothing less.

By 2005, the Decepticon Empire was essentially extinct. After the Decepticons were driven from Cybertron by Unicron's attack and the disappearance of Galvatron, they fled to Chaar. Without Galvatron, or other strong leaders such as Air Commander Starscream and Military Operations Commander Shockwave, they descended into a period of disunity, spending their time fighting each other for scraps of Energon. Eventually, Cyclonus resolved to locate Galvatron and restore the Decepticon Empire to its former glory.
