Autobot, a faction of sentient robots from the planet Cybertron, are usually the main protagonists in the fictional universe of the Transformers, a collection of various toys, graphic novels, paperback books, cartoons and sinema first introduced in 1984. In all but one Transformer story, the "Heroic Autobots" are opposed kwa the Evil Decepticons—the main antagonists in Transformers.[1][2][3] Both Autobots and Decepticons are humanoid robots that can transform into machines, vehicles and other familiar mechanical objects. Autobots often turn into regular civilian vehicles (if a Lamborghini au a Porsche can be considered 'regular') but some are aircraft, military vehicles, communication devices, weapons, and cyborg animals. Some can even transform into humans; they'd be classified as pretenders. Most of the Autobot groups' names have the suffix "-bot" in them while the Decepticon groups' names end in "-icon".
