As a top university research scientist about to run out of funding, Robert O'Hearthy was desperate for a breakthrough. The Genetic Modification experiment worked on hamsters, cats and dogs, but not on chimps. But he knew that wouldn't be an issue on humans because humans didn't have the same complication. So Robert became the experiment's first and only subject. The Experiment gave off extreme gamma radiation, turning Robert O'Hearthy into a being with the ability to change his form into a beast with super-speed, super-strength and limb regeneration. Obsesed with perfecting his experiment, he convinced himself to stop at nothing to accomplish it.
