Atomic Rabbit

Atomic Rabbit was a lot like Atomic Mouse, but with a species change and a couple less supporting characters. He protected Rabbitville, rather than Mouseville, from the depredations of Sly Fox, rather than Count Gatto. Instead of an inept assistant, Sly had two kids.

He, too, got his super powers from doubly-forbidden fruit by today's standards — drugs and radiation. But while both their power-enhancers were as radioactive as can be, Mouse's was more blatantly a drug. He got his super powers from U-235 pills, whereas Rabbit's U-235 carrots could be passed off as good nutrition, like Atomictot's vitamins and Popeye's spinach. But while Popeye of the E.C. Segar comics ate lots of spinach for strength through nutrition, the animated Popeye treated it like a drug, getting a huge rush from it and sometimes, just for emphasis, sucking it in through his pipe. Good nutrition or not, Atomic Rabbit definitely fell into the category of drug-based superheroes.
