Gaining a super-genius intellect after falling into a vat of gamma irradiated waste, Samuel Sterns became the power hungry Leader. Not satisfied with only his increased intelligence, the Leader creates a device that will transfer the Hulk's physical strength into himself! Now possessing the Hulk's gamma-amplified strength and his own increased intelligence, the leader is the single most powerful entity on Earth! With that much power, only one person has a chance to stop the insane villain-The Incredible Hulk!

Joining the Leader Hulk during his experiments is his evil henchman, the Gargoyle. Complete with a techno launching action base, the Gargoyle is ready for batlle [sic] alongside the unstoppable Leader Hulk!
