funny story i heard through the grapevine:
the one of the originals creator of Pixie along with a few dozen other mutant's based Pixie off his (at the time) young underage sister. Then one of the many mutant killing events happened which marked the end of the creator to move onto some other marvel project. Most of his teams mutants were killed, with Pixie being one which was spared.
Well skip to the next time he saw Pixie and she had the proportions close to that picture. His jaw dropped and he said "my god they turned my sister into a slut..."
