I came upon this interesting piece of Marvel history to share with you. From CBR:
Randy Schueller, fan and originator of the black Spider-Man costume!
"I thought it would be cool if Spidey needed to upgrade his powers and his look, so I came up with this idea that Reed Richards had made a new costume for Spidey using the same unstable molecules that the FF costumes are made of. The unstable molecules would flow into Peter's pores and allow him to cling to walls better. I think my original idea was to increase his sticking power by 25% or something like that.
For some lame reason, I had the Wasp involved since she was the resident fashion plate of the Marvel universe at the time. Anyway, I saw the new suit as a stealth version of the original costume - jet black so he could blend in with the shadows. At best, all you could see of him was the blood red spider emblem, emblazoned on his chest. (Yeah, in my design the spider was red, not white. I also gave him underarm webbing like in the original Ditko design.)"
-I find it very cool that the then Editor-in-Chief gave a fan a shot. The black costume has become an important part of the Marvel Universe. I doubt something like this would happen again, but for those with creative aspirations, here is Marvel's address.
