"The name was meant to demonize us. Instead, we wear it as a badge of honor, for if speaking the truth is deception, then we are gladly guilty."
Megatron explaining the origins of their namesake to Orion Pax.

The Decepticons are a group of Cybertronians whose original goal was to get rid of the Caste system on Cybertron and return to the empire-building, space faring ways of their ancestors. The name "Decepticon" came from pre-war propaganda by the Autobot High Council labeled that 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, then [they were] gladly guilty".

In the Great War and long after, they were opposed by the Autobots. Occasionally, both sides would put aside their differences for mutual threats only to resume fighting later.



When the original Thirteen Primes helped their creator Primus defeat his twin brother and rival Unicron, conflicts fueled by discord slowly spread among their ranks as time went on after the Chaos-Bringer's defeat. Tensions ultimately reached a breaking point when Liege Maximo and Megatronus Prime got into a fight that resulted in the death of Megatronus' lover and fellow Prime, Solus Prime, when she was hit with a blast from her own creation and one of the ancient artifacts of the Primes called the Requiem Blaster, an action that resulted in the creation of the Well of Allsparks from Solus' lifeless body and Megatronus earning the titles of "The Fallen" and the "First Decepticon", something that would live on in Cybertronian history even after the remaining Primes banished him to a different dimension.

Transformers Prime

The Decepticons were a Kaonian movement started by a miner named Megatron to bring forth 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 rank of Prime, he ordered his followers to fight and take over Cybertron by force. During 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 them using Dark Energon causing 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. Right after the final defeat of a resurfaced Unicron, Megatron disbanded the Decepticons' cause and exiled himself, retreating to parts unknown. Starscream attempted to rebuild the Decepticon cause, though he was quickly stopped when he was confronted by the three Predacons.

Transformers: Robots in Disguise

Despite their break up by the reformed Megatron, some Decepticons still chose to continue with their villainous cause, notably Steeljaw, who sought to reunite the Decepticons who would later be under his command on Earth. A number of Decepticons were also imprisoned aboard the Alchemor and escaped after Megatronus caused it to crash-land on Earth. The Decepticons of post-war Cybertron seem to be more or less represented by criminals and other Cybertronian low-lifes, rather than former warriors of the original faction.


The earliest Decepticon members were gladiators such as Blackout, Lugnut, Drixco, and Barricade. Shockwave was a scientist who joined the Decepticons and served as Megatron's chief scientist and second-in-command. Soundwave and his Mini-Con deployers Laserbeak, Ravage, Rumble and Frenzy, were also among the first modern Decepticons. During the Great War, Breakdown, Knock Out, Airachnid, Makeshift, Headstrong, Rampage and Tantrum all joined the faction. Axer 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 his Seekers, perhaps even Skyquake and Dreadwing, joined the Decepticons. Starscream was later promoted to the position of second-in-command. Ratbat and Contrail joined the 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, some time before Fall of Cybertron. As mentioned above, the later Decepticons of the post-war era on Cybertron, and ultimately in the universe, appear to be simply composed of common crooks and thugs rather than disciplined and well-trained warriors.

  • The Decepticons show up in most Transformers genres as the antagonists. They also show up in the live action movies as the antagonists.
    • The Decepticons were led by Megatron. In most series, Megatron would die but would also come back to life in a new body or his old body.
    • This is the first incarnation in which the faction is disbanded.
    • The Autobots are their true enemies.
    • This is the first incarnation of the faction that has generics make up the majority of their army. The main characters in this series act as supervisors, officers or commanders.
    • The Decepticons mostly speak English but they can speak Cybertronian in their conversations.
    • The Decepticons from Robots In Disguise often have an animal theme to either their robot or alternate modes, whereas the Decepticons seen in Prime all had vehicle alt-modes and humanoid Robot modes.
    • The Decepticons firmly believe that Cybertronians are the greatest, most superior form of life through out the galaxy. While they leave other mechanical races alone to develop as they will, this translates to the "cleansing" of organic worlds, but they have, however, no qualms killing any Cybertronian that stands in their way.
