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."
Dinobots
The Dinobots are a group of Transformers, part of the Autobot faction. Their origins and abilities vary from one version of Transformers to the next, but they are generally depicted as powerful Autobots capable of sustaining heavy damage and wielding heavy firepower against their foes. Like most dinosaurs that existed, they are not very smart. They are the only known Autobot group—other than the Aerialbots—capable of flight in robot mode, a trait they share with the Decepticons. They are always portrayed as fiercely independent, and are prone to diverge from the main group of Autobots to pursue their own agenda. All Dinobots' names (except Grimlock) begin with the letter S.The Dinobots in the original Transformers cartoon were built on Earth by the Autobots Wheeljack and Ratchet. Seismic activity near the Ark resulted in Ironhide's discovery of dinosaur bones, and Wheeljack was inspired to build three dinosaur-based Transformers: Grimlock, Slag, and Sludge, collectively called the Dinobots. They were incapable of any cognitive reasoning, and even failed their first simple task assigned by Ratchet when activated as seen in episode eight, "S.O.S. Dinobots". They immediately turn on the Autobots like wild animals, and nearly destroyed the Ark, forcing Optimus Prime to order their destruction. Wheeljack's magnetic inducer was the only thing that stopped them. Being nearly indestructible, the next alternative was to seal them away forever, deactivated. That same day the Autobots were caught off guard by a Decepticon ambush. Their friends having been captured and on the verge of destruction, Wheeljack makes a snap decision and installs the upgrades to the Dinobot's brains just before sending them in to their initial engagement against the Decepticons. Upon their arrival and subsequent victory over the Decepticons, Optimus Prime agrees that the Dinobots shall remain among them.
