[Western Crossover] Catch That Writer of Little [Redacted]!

Black Goat is the most popular author on the fanfiction website Avengers Alliance, a true paragon of talent and character with astonishing writing skills and an imagination that knows no bounds! Using all kinds of superheroes as inspiration, he writes fanfiction short stories, with fluff, angst, and smut. His most distinctive trait is his unconventional style: as long as a pairing exists, he'll write it! For example, on his first day he wrote about the first love of Stucky; on the second, the bickering relationship of Stony; on the third, a bizarre Thor and Iron Man pairing; and on the fourth, the rare Hawkeye and Black Widow pairing! The problem is that many of the things he writes about actually happen! Some could even happen in the future! For example, he wrote about Tony Stark getting kidnapped back when Tony was still a playboy. Before Cap was even dug out, he wrote about Cap's promise to Peggy. And while Thor was still in Asgard, he wrote stories about the divine brothers... And so Black Goat became the number one name on S.H.I.E.L.D.'s watchlist, all through sheer talent.

"But I actually kind of like him." Iron Man found the power fantasy about Iron Man as the top in the relationship pretty satisfying. "It's just that he said I wear elevator shoes? I never wear those!"

"It brought back a lot of painful memories, but it really is what I feel." Black Widow smiled with a complicated look in her eyes as she read The Winter Princess.

"I had no idea my little brother could have a baby. So is he actually my little sister?" The God of Thunder read all kinds of X-gene pregnancy smut and lamented that he was a terrible older brother...

But just who was this Black Goat, who had set the fanfiction world ablaze, given S.H.I.E.L.D. a massive headache, sent the X-Men into action, and left Hydra gnashing its teeth?
