Mirage is what humans call "old money." Before the war, he was a member of affluent Cybertronian society, with his own large estate and high-priced friends. He enjoyed the finer things in life: drinking vintage Energon, swank evening events, and turbofox hunts on the grounds. But when the war started, he was forced to choose sides and found himself banded with a group of commoners he didn't really understand. Although the details vary by continuity, Mirage has the ability to create illusions which typically either render him invisible or make him appear to be somewhere he isn't.
