Transformers Generations Wheeljack
Generations Wheeljack is a retool of Transformers Turbo Tracks, featuring a new head, wings, clip-on wrenches that replace the missile launchers, new vehicle mode front fenders and rear spoiler.
His constant need to invent increasingly complex devices stems from his desire to improve the Autobots’ tech.
But as a result he’s simultaneously one of the Autobots’ greatest assets and problems.
For every successful gadget he builds, there is one which requires Ratchet or Hoist to put him and his lab back together.
But once in a while he strikes gold, which has won him respect from even the Decepticons.
