Movie plot
Wheelie first appears in Transformers: Revenge of the Fallen. He was sent by Soundwave to spy on Mikaela Banes, who is given a shard of the All Spark by her boyfriend Sam Witwicky. However when trying to steal the shard from a vault he is immediately caught by Mikaela, who destroys his left eye with a blowtorch. He pleads for her to give him the shard as The Fallen needed it and would die if he failed. She then locks him in a suitcase and flies to the East Coast to rendezvous with Sam. When Mikaela, Sam and his dorm mate Leo Spitz meet up with former Sector 7 agent Seymour Simmons, Mikaela releases Wheelie from the suitcase and convinces him to translate the symbols from the Sector 7 photo archives. He tells them that it was the language of the Primes and couldn't read it, but offered to find them someone who could. He then helps the humans locate the former Decepticon Jetfire at the Steven F. Udvar-Hazy Center in Washington, D.C. After Jetfire is awakened, Wheelie swears allegiance to the Autobots as he hates the Decepticons. He joins the group in searching for the Matrix of Leadership in Egypt, but disappeared after a while. Wheelie reappears in the 2011 film Transformers: Dark of the Moon. He was Sam's 'pet', along side his new friend Brains. Wheelie and Sam have been dumped by Mikaela and Wheelie isn't entirely happy with his and Brains' "living arrangements", as the U.S. government didn't care for the two small robots. His damaged eye is already healed in the third film. Later they are among the Autobots as they are exiled from Earth and presumed killed as their ship is blown up by Starscream. During the battle in Chicago, Wheelie stated the Autobots were staying to win the war, and though excited to help, he is angry when he and Brains are accidentally left behind by the Wreckers. Wheelie and Brains wandered the streets and used a crashed Decepticon fighter to fly to the main battlecruiser. Once there, he and Brains sabotaged the ship, saving Bumblebee and the other captured Autobots, and the ship came crashing down in the water. Their survival is a mystery.
