Ah the "House of Idea", as Stan Lee called it. And it definitely was that and much much more. However, his publisher was also known in some circles as the "House of Recycled Ideas". Need proof? Consider these guys:
Okay, a homo sapien turned into a fly. Got it. A guy in a special suit that gains strength and becomes a human shield. Sure. A dude that inhales fumes allowing him to fly and emit radiation to transform into a living comet. Um, alright. And a rope slinging vigilante who, after figuring that his long last relative (read: living comet) is dead then decides to avenge his death. Whatever. Where have I heard this before?
Oh yeah! The Fly, Shield, Comet and Hangman! What a coincidence!
Or not. Stan Lee was allegedly not very keen on Mighty Comic's mocking of his style of comics and editorial writing (such as Jerry Ees for Siegel) and in the 1970's decided to do a back handed slap at his one time wimpy rival over at Archie. However, the most blatant copy, in this writer's humble opinion, was leveled against Charlton who always minded their own business and even revered the powerhouse publisher:
Two military captains gaining cosmic powers clad in bright garb traveling through space to champion a heroic age! Make Mine Mighty Charlton!
