His own past is a mystery to Wrecker Hook. With no memory of his creation or who he really is, he stays with the Decepticons, thinking he might find answers one day. He is a skilled mechanic who can effect repairs on most anything, and does so without complaint. He seems to be friends with Wing Stun. On the battlefield, however, Wrecker Hook is a danger to everyone around him, especially once he starts swinging his "Boost Hammer" weapon around. This might be a sign of his past self, or it could just be another result of some scrambled circuits.
