* 1ST APPEARANCE "BAG O'BONES" (Ned Creegan)

Ned Creegan was just an ordinary crook who was tipped off about valuable jewels from Billy Blabbermouth that were being used for scientific tests in the northern suburbs of Gotham City. The home he breaks into belongs to scientist Nevil Logan, who passing radiation through the gems to find out their effect on living creatures by exposing them to farm animals. Knocking Logan out, Creegan steals the gems and takes them to his fence.

There, the sale of stolen goods is interrupted by Batman and Robin, who battle the fence and the crook. While Robin easily knocks out the fence, Batman is shocked to see Creegan's body become transparent leaving only a skeleton in it's place. Dubbed "Bag O' Bones" by Robin, Creegan easily defeats the Dynamic Duo with his new electrified touch. Escaping back to Logan's lab, Ned orders the scientist to figure out what's wrong with him. Explaining he was attempting to come up with a means to make people immune to the effects of a nuclear bomb attack in case of a nuclear exchange between the United States and Russia, Nevil created the experiment. Having developed a temporary antidote from the side effects of the radiation, and providing them to Creegan, Logan explains that while he is his "Bag O' Bones" form he loses a day of his life for every second he's in that form. When calculating that in linear time, before he took the temporary antidote, Creegan figured he has lost four years of his life. The two agree to work together as Logan intends to use his results to sell to the highest bidder.
