Ant-Man

A tiny, foot-high man, clad in a bright red costume, who appears in Gotham City in June 1963, helps Robin apprehend a gang of criminals led by mobster Al Welles, and then, to Robin's surprise and consternation, makes off with a satchel full of the very jewelry that Welles had been trying to rob. Ant-Man is in reality Jumbo Carson, a "rival mobster" believed dead at the hands of the Welles mob, who actually escaped his own attempted gangland assassination and shrunk to his present size when he fell into the river running past Hanson's Research Laboratory - where Professor Hanson was experimenting to perfect a formula to "shrink living tissue" - and was bathed in the weird chemical discharge from Hanson's lab. Car­son then assumed the identity of Ant-Man in order to strike back at the Welles gang for attempting to kill him. Ant-Man, who will probably remain small forever due to the lack of an antidote to the chemical mixture that affected him, is apprehended by Robin in June 1963.
