Transformers: Galactic Force

Cybertron, a planet inhabited by a race known as the Transformers, was ravaged by civil war following the Cybertronian War of Independence against the Quintessons (sometimes colloquially known as the Quintesson War). The Autobots, realizing that the war is draining the planet's natural resources dry, migrate to another planet. Little did they know that the planet they were migrating to had already been populated by a group of Transformers that had been living amongst the human population.
