Not long after Power Man went into business with Iron Fist, an old enemy from Power Man's days with the Defenders came looking for revenge. But as a side effect of an adventure the previous issue, Luke Cage had no super powers when ambushed by Arthur Nagan, a.k.a. Gorilla-Man of the Headmen (Power Man and Iron Fist #68).
Unquestionably outmatched, Luke Cage did his best to flee … until an attack from Gorilla-Man flung the hero-for-hire into an electrified fence and unexpectedly reinstated his powers.
Just as Iron Fist arrived at the scene, Power Man delivered the closing blow to Gorilla Man by slamming the villain into the ground head-first.
