Scrapper is the engineer of the Constructicons. While the other Constructicons put their masterpieces together, Scrapper is the one who designs everything for them. His designs are among the best in Transformer history, however, 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.
