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."

While the Autobot's presence is not known among the general population, the United States government is aware of their presence and cooperates with them. A special agent named William Fowler often communicates with the Autobots directly. Megatron discovers that Optimus is on Earth and seeks him out to destroy him. Megatron also realises that Earth is rich with sources of Energon, and the Autobots strive to stop him from destroying Earth as he searches for these sources. Energon is the emanation of Primus, the creator of the Transformers, and it functions in transformers as blood does in humans. Dark Energon, on the other hand, is a corrupted form of energon and the blood of Unicron the Chaos-Bringer, Primus's fallen brother. Primus makes up the core of Cybertron, and it is eventually revealed that Unicron makes up the Earth's core. Megatron injects himself with Dark energon in order to gain control over it and become stronger. Dark energon weakens and corrupts transformers, and it can be used to raise the dead, which Megatron does in the beginning of the series.
