Gobotron

Gobotron is an alternate universe's version of Cybertron. One would be unsurprised to know that the planet is home to transforming machines who are having a civil war, but these guys are actually the cyborg GoBots, with the Guardians police force protecting from the constant Renegade insurgencies.

MUX Continuity
When Mirage destroyed a nexus of the Space Bridge, a whole was ripped open into another universe. Denizens of that universe came to ours, where they remained until the rift was healed.

Shattered Glass
When a Cataclysm began to threaten the very existence of the universe, the inhabitants of Gobotron ceased their conflict, united with Earth, and held an emergency summit. It was decided to send a combined team to the 22nd Level, the dimension causing the disaster, and try to reverse the damage.

Once there, many of the travellers took sides in the growing conflict on Cybertron, and remain with the Autobots and Decepticons to this day.
