A fictional faction of evil sentient alienrobots from the planet Cybertron. They are usually the main antagonists in the fictional universe of Transformers.
These villainous transforming robots can 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. Primarily, Decepticons have red eyes, while their enemy Autobots have blue eyes. They are usually known for their air power, especially since many of them turn into aircraft. Decepticons often turn into military vehicles, construction vehicles, and even smaller-than-human-sized objects.
In Japan's version of the franchise, 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).
The title Decepticons is derived from the word "deception" in the English language.
