List of Autobots
This is a list of known Autobots in the Transformers fictional universe and toy line. The alternate modes of Autobots are usually cars, trucks, and various other ground-based civilian vehicles, to contrast with the military vehicles favored by the Decepticons (see List of Decepticons). One of the most notable Autobots is B-Skaf, who could turn a van into a train."Powerdashers are mail order Transformers whose name stood for one of three available molds."
Cybertron
Knowing nothing of their true origins or the destiny they were to fulfill, the Transformers eventually splintered into two factions – the politically dissident Decepticons, who waged war on the peaceful Autobots. Megatron, leader of the Decepticons, schemed to turn Cybertron into the ultimate weapon, a warworld that would wreak havoc across the galaxy, and the resulting war knocked Cybertron out of its orbit and set it adrift in the universe. Around four million years BC, Cybertron's path brought it into the Sol system, heading directly for the asteroid belt, which threatened to heavily damage the planet. Autobot leader Optimus Prime led a contingent of his warriors aboard the Ark to destroy the rocks in Cybertron's path, but once they had succeeded, they were attacked by the Decepticons, causing all involved to be trapped in stasis on prehistoric Earth.
