the Autobots are one of the primary factions in the Transformers mythos. They usually find themselves defending both their own race and other species against the Decepticons and upholding justice and freedom throughout the galaxy.
They are considered "the good guys" in most, but not in all Transformers stories.
A generally heroic, honorable group, they tend to be dedicated to peace, and feel a need to protect other races from the Decepticons. As a result, they are usually Transformers who change into non-combat oriented alternate modes such as domestic vehicles, cars, trucks, or rescue vehicles. This is not alwaysthe case, however, as their ranks certainly contain ne'er-do-wells, malcontents, and unsavory types, and the necessities of war have led many to adopt more combat-oriented alternate forms. While the Autobots have usually found themselves outnumbered by the Decepticons, the Autobots have always had home-field advantage.
"Autobot", a contraction of "autonomous robot", was an old philosopical phrase Orion Pax found on the DataNet and one that he suggested to his friendMegatron to be the name of their movement to abolish the caste system. At their hearing with the High Council, Orion used the term over and over again to remind his enthusiastic followers of the freedom they sought. He implored the Council choose a new Prime, so Halogen chose Orion as the new Prime, tearing Orion and Megatron's movement in two. In the war with Megatron's Decepticons, the Autobots only held fifteen percent of Cybertron, including Iaconand Kalis. The Autobots left Cybertron on the Ark, transported by the space bridge to the milky way galaxy. Ultra Magnus's Wreckers, Jetfire, Omega Supremeand Alpha Trion remained on the planet.
