Planet Cybertron was the planet from which all of the Autobots and Decepticons hailed.
- Part of the Bubblegum Galaxy
- Was at one point peaceful, but Megatron and company would have none of that shit
- Was such a shithole that the Allspark blasted itself off into space to get away from it
- After Sentinel Prime and Megatron try to bring it into Earth's atmosphere for some reason, the space bridge transporting it is destroyed and Cybertron is sucked into a vortex and obliterated
- Was home to extraordinarily stupid robots, if you couldn't already tell
