The Constructicons emerged before the war with the Autobots and High Councilor Drivetrain was considered their patriarch. They were generally larger than Megatron's gladiators, which was why he chose not to bring them with him when he tried to access Teletraan-1, as the Iacon-Kalis energy line would be unable to fit them. During the civil war, the Constructicons combined into Devastator and ravaged Crystal City and Tagan Heights, and separately attacked Praxus with Bruticus Maximus. Two Devastators pursued Autobot Mini-Con saboteurs through Tagan.
