Decepticons are usually depicted as the evil faction in the fictional universes of the Transformers stories and comics and cartoons, and they are the enemies of the Autobots. The villains take many forms, and have many different origins and stories across the numerous different Transformers media, but in almost all incarnations, they are led by Megatron. They are typically represented by the purple facial insignia they all wear.
Decepticons usually have red eyes and Autobots have blue eyes. Decepticons are known for their air power, especially since many of them turn into aircraft. They often turn into military vehicles, construction vehicles, and even smaller-than-human-sized objects.
In the Japanese version, the Decepticons are called Destron or Deathtron (Japanese: デストロン Desutoron). The one exception to this naming convention is Car Robots, where the sub-group referred to as “Decepticons” in the Robots in Disguise adaptation, is known in Japan as the Combatrons (the Japanese name of the G1 subgroup known as the Combaticons). The overall name of the Robots in Disguise villain faction is Destronger. However, the Japanese Version of Transformers Animated uses Decepticon (ディセプティコン).
Transformers: First Generation
The evil Decepticons are from a race called Transformers – robots that can change into vehicles, mechanical devices and even animal forms. They waged war for eons on their home planet of Cybertron against the heroic Autobots. Both factions needed supplies, and select numbers from each side intended to get them. The Autobots weren’t looking for a fight with the Decepticons, but they get one out in space anyway.
When the Decepticons board the Autobots’ ship it takes a beating and crashes onto Primitive Earth and knocks everyone unconscious. Millions of years later, in 1984 a volcano eruption causes a probe to give them all new forms which come from vehicles in the surrounding area. After the featured film The Transformers: The Movie, Megatron was reformed as Galvatron, and Optimus Prime was replaced for a time by Rodimus Prime, only to return later on.
The above tattoo is a very detailed and interesting Transformers half shirt & sleeved tattoo. On one side was the Autobots and the other side featured the Decepticons.
What does a Decepticon Tattoo mean?
It’s to symbolize how so many things are contradictions which is what is cool about it. Decepticons in the first generation transformers were evil but later generations have more depth.
Symbolism for the Autobot symbol is personal responsibility and Justice. It doesn’t mean the good guys as much as it means that the followers of that symbol believe in a philosophy of taking moral accountability for their actions. Autobots tend to be good and fight for freedom because they think everyone is capable of personal responsibility to a moral good.
