When Optimus Prime and the others were captured by the Quintessons, the remaining Autobots aboard the Ark contemplated their next move. Sunstreaker mentioned Mirage as part of a strike force he would assemble to rescue the big guy and their friends.
As Sideswipe flew the Autobot spaceship through the Quintesson artillery, Mirage, Sunstreaker, and the rest of Strike Force Zero dropped from the ship to reinforce their fellow Autobots, who had already broken free and engaged the Sharkticons.
Following the restoration of Cybertron from the Great War, Mirage was one of the many Autobots blacklisted by the new High Council for being a supporter of Optimus Prime.
Mirage is based on a Generation 1 Autobot whose Alternate Mode on Earth was a race car and who possessed the ability to make himself invisible. This Mirage's colors, however, appear to be based on the Mirage from Transformers: Dark of the Moon.
