Wheeljack, a former member of the Weckers, was a major recurring character in Transformers Prime. A somewhat cocky, reckless loose cannon, Wheeljack dislikes obeying authority, but is still a firm ally of Team Prime, especially his fellow Wrecker, Bulkhead.
Despite his "lone wolf warrior" personality, Wheeljack is still described as an engineer. It has been alluded to in Triage with him fixing his ship in very short time. In Evolution he further adds to this by performing maintenance and upgrading Ultra Magnus' ship and in Persuasion by aiding Raf build his transponder with Laserbeak's clipped wing.
