Notable appearance: Batman Returns
We’re not denying the Caped Crusader’s accuracy, but even the best of us need some help every once in a while. That’s why in Batman Returns he pulled out a computerized Batarang that automatically targeted nearby enemies and flew around with a mind of its own, seemingly. It worked by traveling on a predetermined path that Batman punched into its miniature console.
This was a convenient way to ensure accuracy and defeat numerous foes with one throw. Unfortunately this gadget has never been seen again in any medium. It seems like even a billionaire has his limits, and this might have been a bit too costly for his bat budget.
