Power Man And Iron Fist, Vol. 1 #71A (1981)

The Mountain Comes To Manhattan
Iron Fist notes the terrified passage of "Marco". Elsewhere, Harmony Young take Luke to one of her shindigs, but Luke reacts badly to being asked "to do a few tricks" and storms out. He visits a diner where Marco is dining. Marco flees into an alley where a pursuer catches up to him. This is Montenegro, the "Man from the Black Mountain". Sometime later, a man named Thisby offers Luke $10,000 for a quarter - but Luke does not realize Thisby wants a specific quarter that Marco left behind, and that Luke received a change! Thisby works... for Montenegro! The villain attacks the pair at the Gem, seeking his quarter! He comes bearing a gun meant to fire pitons into cliff faces - can even Luke's steel-hard skin withstand that? And with Danny roped and hauled aloft, Luke faces two perils! He climbs, but Montenegro has the drop on him. Unless Danny can help. And what's so special about that quarter, anyway?
