Mirage is an autobot, although his allegiance is wavering. He is unsure of the Autobots cause and cannot always be trusted.

He transforms to a Formula One race car and uses his speedy ability for intelligence gathering and reconnaissance. Mirage also has a rifle mounted cannon which fires explosive, armor-piercing darts. With the rifle, he can shoot a screw head 200 yards
away. As an intelligence gather, his most important piece of arsenal is his shoulder-mounted electro-disruptor, which bends photons to make Mirage invisible, or appear to be where he is not, or even alter his physical appearance, hence his name.

Mirage is slick in appearance, functions as a spy and intelligence gatherer, can turn invisible, and is a fast expensive sports car. He's the James Bond of Transformer.
