The Decepticons (Autobots being their enemies) are usually depicted as the Antagonists in the fictional universes of the Transformers toyline and related comics and cartoons. 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. Primarily, Decepticons have red eyes, while Autobots have blue eyes. They are known for their air power, especially since many of them turn into aircraft like Starscream. They can turn into military vehicles, construction vehicles and even smaller-than-human-sized objects, like Frenzy, who is in Barracade's chest.
