Scrapper is the engineer of the Constructicons. While the other Constructicons put their masterpieces together, Scrapper is the one who designs everything for them. Though his designs are among the best in Transformer history, Scrapper is a modest Decepticon who quickly shrugs off the praise he receives. In that respect he is the polar-opposite of his frequent second in command, Hook, who is an egomaniacal glory-hound.
Though modest, Scrapper is still a total nutcase. One of his favorite artistic liberties with his designs involves taking living Autobots and using them as raw materials. This vicious act is something Megatron finds admirable, as he considers Scrapper the most valuable of the Constructicons.
? BCE (Before the Great War)
Megatron Origin 2 – Scrapper and the other Constructicons built arena sites on Cybertron for the illegal gladitorial matches. At one point, Megatron, together with Rumble and Frenzy arrived too early. There they met Soundwave who offered weapons and technology. Megatron discovered two spies, and killed them both, learning that the gladiators were hunted by the Autobots. Megatron ordered Scrapper to quit building and leave the site.
Megatron Origin 3 – As the other Constructicons, Scrapper makes repairs to Megatron’s gladiator team after a fight. He was there when Soundwave came in and introduced the Seekers to Megatron.
