When a prototype military vehicle with a disastrous flaw is abandoned and seized by Jokerz, Batman and the vehicle's creator must hunt it down before it explodes.
The skeleton in the mine still has a scrap of purple suit and flower on it. As this was before the creative team had conceived of the story for "Return of the Joker", it could be surmised that this an allusion to the final fate of the Joker. Alternatively, it could simply be one of the other initiates who did not survive, but the individual in this episode is wearing regular clothes as opposed to entering the initiation in Joker garb.
Jokerz Leader:
Nice ride, Scab. Where'd you get it?
Scab:
My grades were good, so my folks bought me a car.
