The Decepticons are a Cybertronian faction from different parts of the Multiverse that generally have policies including militarism, Cybertronian equality, neo-technoism, imperialism, and genocide. It should be noted that the Decepticon faction is very different from universe to universe and sometimes different waves of Decepticonism are different within the same universe. In many universes, Decepticons are not a faction but a race of Cybertronian and/or serve as the faction/race that establishes the Decepticon Empire. Some universes have the Decepticon race evolve into the Predacons.

The Decepticons were a faction of Cybertronians under the command of Megatron. They became embroiled in the Autobot-Decepticon War against the Autobots. Though the war escalated with the creation of the Combiners, the war ended without a clear winner and Megatron abandoned the Decepticons. Though the war was over and the former Decepticon Starscream sat on the Council, tensions remained between the Autobots and the Decepticons.
