The Decepticons are the main antagonists in the fictional universes of the Transformers multimedia franchise. They are depicted as a faction of sentient robotic lifeforms led by Megatron, identified by a purple face-like insignia. Capable of transforming into alternate forms, these are often high-tech or powerful vehicles; including aircraft, military vehicles, construction vehicles, expensive luxury or sports cars and even smaller-than-human-sized objects.
