Scrapper is a Constructicon Scout that transforms into a front load shovel. When combined with his fellow Constructicons, he becomes the right arm of Devastator. He may also share a name with another loading scout who saw action at the battle of Egypt. Or yet a third one who saw action in the battle of Chicago.
During the climactic battle in Egypt between the Autobots, their human NEST allies and The Fallen's Decepticons, Scrapper appeared in a quarry with the other Constructicons before merging into Devastator to attack former Sector Seven agent Seymour Simmons, Leo Spitz, Skids and Mudflap.
Meanwhile at the Egyptian town, another Decepticon with Scrapper's body-type joined Starscream's group to search for the fugitive Sam Witwicky. When the boy and Mikaela Banes were flushed out of hiding, Scrapper attempted to crush them with his fist/mace on a chain, but the humans escaped in the chaos.
Elsewhere, as Devastator smashed away at the Great Pyramid of Giza after shrugging off Skids and Mudflap, Simmons called upon the United States Navy to fire upon the giant Decepticon. The U.S.S. Kidd fired her experimental railgun, smashing the Scrapper arm to pieces and destroying Devastator. Back at the Egyptian town, the other Scrapper was destroyed when the United States Air Force bombed the heck out of the battlefield.
