The Decepticons are a group of Cybertronians, whose main goal was to bring about change on Cybertron due to the Caste system and return to the empire-building, space faring ways of their ancestors. The name "Decepticon" comes from the fact that pre-war propaganda by the High Council labeled them as liars and thieves. They took the name as a badge of honor instead. In their minds if speaking the truth was a deception, they were gladly guilty.
The Decepticons were a Kaonian movement started by a miner named Megatron to bring a new world order on Cybertron, with him as their leader. The majority of the Decepticons were originally low-ranking members of society such as miners but some were members of higher castes craving more power such as Ratbat. They held similar goals to the Iaconian movement of the Autobots but differed on how to obtain them. When Megatron was denied the Matrix of Leadership and the rank of Prime, he ordered his followers to fight and take over Cybertron by force. In the war, their noble ideals quickly became corrupted and they became almost completely amoral, willing to seize power by any means available. This led them to the use of Dark Energon which caused the core of Cybertron to shut down. The Decepticons, like the Autobots, took to the stars continuing their war across the galaxy.
After Bumblebee killed Megatron, the Decepticons were left in complete disarray and the losers of the Great War by default. After the defeat of Unicron, Megatron abandoned the Decepticon cause and exiled himself upon announcing the group's disbandment, while his command staff either defected or went missing. It is likely that other Decepticons still exist on Cyberton and in the galaxy.
Despite their break up by the reformed Megatron in the prequel, some Decepticons still choose to continue with their villainous cause. Notably Steeljaw, who seeks to reunite the Decepticons under his command at Earth.
The earliest Decepticon members were gladiators such as Blackout, Lugnut, Drixco, and Barricade. Shockwave was a scientist who join the Decepticons and served as Megatron's chief Scientist and Second-in-Command. Soundwave and his Mini-cons (Laserbeak, Ravage, Rumble, Frenzy) were also part of the first Decepticons. It is unknown when during the Great War Breakdown, Knock Out, Airachnid, Makeshift, Headstrong, Rampage, and Tantrum, all joined the faction. Axer had left Cybertron shortly after Orion Pax was said to be a Prime by the High Council, but sort of joined them when the Nemesis arrived at the planet Junkion. During the Events of War for Cybertron, Starscream and many of the Seekers (perhaps even Skyquake and Dreadwing) joined the Decepticons. Starscream then or a while later was promoted to the new Second-In-Command. Ratbat and Contrail either joined the Decepticons or were confirmed as Decepticons when The High Council nominated Orion Pax as the Next Prime. The Combaticons and Constructicons were built before the War for Cybertron events. The Insecticons joined the Decepticons during Rise of the Dark Spark, before Fall of Cybertron.
