The Autobots (full name is Autonomous Robotic Organisms) are a faction of sentient robots from the planet Cybertron created by the Creators, and the main protagonist faction of the Transformers Cinematic Universe.
Initially, they were chased by the military who want to catch them, until after the battle against Megatron, the two races made a truce and formed an alliance to destroy the surviving Decepticons. After the Battle of Chicago, all Transformers are wanted, both Autobots and Decepticons, and the soldiers who chase them do not intend to capture them alive, but kill them for KSI experiments. The first group to hunt down Autobots is Cemetery Wind, led by Harold Attinger, but after Attinger's death, the new group that wants to exterminate Transformers is the TRF (Transformers Reaction Force), however, this group is allied with them and Cade Yeager to stop a far greater threat of an alien war between Autobots and Decepticons: the collision between the Earth and Cybertron.
