Mirage, also known as Zeno, is a slick, new Autobot in the Dark of the Moon film.
Mirage makes his debut in Transformers: Dark of the Moon, when he goes on a mission with Bumblebee, Sideswipe and Wheeljack toward the nuclear reactor site, Chernobyl. He crashes through a gate and attacks several guards, telling them to get down and stay down on the ground, as the other Autobots make it to the power plant.
Mirage later appears in the Highway Battle Scene, alongside Bumblebee and Sideswipe, and encounters the Dreads. Mirage is engaged in brief combat with Hatchet, hooking his whips onto his back and steering him onto a car on the other lane - which kills him. Mirage appeared to have some difficulty doing so.
Mirage is among the other Autobots, as they are exiled from Earth on the Xantium. As the ship is in flight - he is supposedly killed alongside the others. Luckily, he survives with every other Autobot on the ship when they hid in the booster rocket that was seperated.
Mirage later appears in the final battle in Chicago, where he, Bumblebee, Ratchet, Sideswipe and Wheeljack are captured by Soundwave, Barricade and several Decepticon Protoforms. After Wheeljack is executed, Wheelie and Brains unexpectedly hiijack a large Decepticon Ship - which begins to release smaller ships, distracting the Decepticons and giving him and the other Autobots a chance to escape. He battles and kills several Decepticons shortly afterwards.
