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."
Sentinel Prime
Sentinel Prime is the name of several fictional characters in the various "Transformers" series in the Transformers robot superhero franchise. First mention of Sentinel Prime was in issue #65 of the US Marvel Comics "Transformers" series, where he was mentioned to hold the Autobot Matrix of Leadership before Optimus Prime. Sentinel Prime is One of the members of the Dynasty of Primes and dedicated as the leader of the Autobots and has since appeared in a variety of forms as either Optimus Prime's mentor or friend. Fun Publications has also had a character in their comic called Sentinel Major, who is based on the "Transformers Animated" version of Sentinel Prime. He is also the main antagonist in the film "," where he betrays the Autobots and later Megatron for his own personal interests. His original "Generation 1" incarnation was later reimagined by IDW Publishing as a similar fallen figure, perhaps in lieu of his movie counterpart.
