The snob of the Constructicons, Hook considers himself an artist. He looks upon the rest of the Decepticons almost as peasants, beneath him to a degree. Though full of himself, Hook is a master craftsman, having truly earned his insufferable ego. His high standards that he holds himself and others to means he takes extra care to ensure even the most simple of jobs is completed to the nth degree of perfection. Although Megatron acknowledges Hook's incredible skill, he gets impatient with the time it takes Hook to finish his work. Hook cannot understand the frustration at the delays this causes, he just sees it as doing the job right.
Hook condescends to join his fellow Constructicons in forming Devastator. It is only fitting that he should form the head and shoulders.
His alt-mode is a golden yellow Crane Truck.
