Transformers: Cybertron - S01

Fleeing their homeworld Cybertron to escape a looming black hole, Optimus Prime and his Autobot forces prepare to relocate to Earth. Before they depart, Vector Prime intercepts them with a dire warning: the galaxy faces destruction unless they recover the four Cyber Planet Keys in time. But Megatron has his own ambitions for the universe. The Autobots set out on their quest, journeying to distant planets where other Transformer civilizations thrive-each world governed by its own Autobot leaders.
