Before Howard the Duck was George Lucas' fourth worst movie, it was a Marvel comic starring the same degenerate human-phile anthropomorphic fowl, and who better to introduce a gang of fire-breathing rockers to the Marvel universe? And so, in the middle of one storyline, Howard witnesses KISS materializing out of a woman's head. They hang around for four more inexplicable pages, just long enough to qualify as a guest appearance, and disappear again with no explanation.
"Just have them show up and sing 'Love Me Do' or whatever." -Stan Lee
Somehow, this led to an oversized KISS comic book that was printed with their own blood (everyone who bought a copy died of syphilis). The story, written by Howard's creator, follows the members of KISS as four regular teenagers who get superpowers -- the same ones they had in the horrible movie they don't want you to see -- from a blind hobo in a furry thong.
Or the saddest vision of He-Man's future.
