One of the first G.I. Joe action figures from the mid-1979s was Mike Power a.k.a. Atomic Man.
Basically a copy of the Six Million Dollar Man Steve Austin, Atomic Man came equipped with cyborg limbs where you could attached helicopter blades and other accessories sold separately.
Instead of a kung-fu grip, he had an ATOMIC Flashing EYE that would either irradiate his foes or at least greatly annoy them into submission.
