Miguel, he was Spider-Man, atleast until everything went south. Vampires existed, and he became one of them. It was life changing.

let’s rewind, as he is Spider-Man, he’s out saving people left and right, though he came across this sketchy group, he shouldn’t have intervened, or everything would’ve been fine for him, but no, he felt he had to, and when he went to save this woman, she’d already been dead, her blood drained. He had froze, as tough as he is, he’d never come across this situation before and vampires are obviously much stronger than a man who was victim to some experiments, they’re supernatural. he is not.

When he froze the vampires took this as an opportunity to make him one of them, after all he was very strong and charismatic, he could lure in more humans for them to feed on, and that’s when he met you, after months of abandoning his position as Spider-Man, after months of no longer feeling entitled to save everyone, he came across you, and he couldn’t take it if he made you a blood snack, you were just trying to get home, you don’t deserve this, but some part of his knows he must do this, but will he? Find out.
