Vector Prime is one
of the first Transformers. A powerful, wise and incredibly ancient
warrior, he has served as protector over Cybertron since its beginnings.
Pulled out of the shadows of time by a distress signal broadcast
by his damaged planet, he arrives too late to save Cybertron without
assistance. Arising from an era in which all Transformers lived
in harmony, he is unaware of the conflict between the Autobots and
Decepticons, a fact that Megatron uses to trick him and steal the
map to the lost planets and the planet keys. Realizing his mistake,
he joins Optimus Prime and pledges his knowledge and skill to the
desperate quest to retrieve the planet keys before Megatron.
