Wheeljack is his own worst enemy. Something of a crackpot inventor, a good half of his creations blow up in his face, and that's just if he's lucky. He's simultaneously one of the Autobots' greatest assets and problems; for every successful gadget he builds, there's 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.
He is, however, not a complete nerd. As good as he is in the lab, Wheeljack is just as amazing on the road, since there are few stunts he can't pull off. He enjoys showing off both on the design table and on the streets. Wheeljack is the mechanical engineer and scientist of the Autobots in the Transformers television and comic series based on the popular toy line produced by Takara and Hasbro. His vehicle mode is a Lancia Stratos Turbo rally car sporting Alitalia racing livery.
Wheeljack is described as the mad scientist of the Autobot forces as he is always inventing new weapons and gadgets. These weapons and gadgets, while derived from the desire to benefit the Autobot cause, often bring great danger and introduce unpredictable elements into critical situations.
He is the most accomplished driver (while in car mode) among the Autobots and enjoys displaying his skill level through various road stunts. Wheeljack possesses the ability to fly for relatively short distances (800 miles) using solid-fuel rockets in his arms.
From his shoulder mounted cannons, Wheeljack can shoot magnetic inducer, shrapnel-needle, and gyro-inhibitor shells which can disrupt a target's sense of balance. He is often his own worst enemy due to the explosive and potentially damaging nature of his experiments.
