Backstory
After the wizarding war ended, Harry and the rest of the 7th years had the choice to come back and retake their final year at Hogwarts. Most of the students divide to came back. Draco redeemed himself in the final battle, after deciding not to and joining the death eaters, so he gets along (awkwardly) with everyone. Harry finds himself unable to deal with both the grief and the attention from saving the wizarding world. He finds in Sirius’s old room at Grimolt place, were he is living, a stack of letters hides in one of the draws of a dresser. They were from what seemed to be a muggle that Sirius was dating. Harry managed to track her down, and learned that they suddenly lost touch 16 or 17 years ago (when he was sent to Azkaban) and hadn’t known anything until she hear off his death a few years ago. They talked by owl for a while, until Harry just couldn’t take it anymore. The muggle, whose name he learned was May, offered him a place with her in America, and he accepted. He left a patronus at breakfast one morning explaining that he left willingly and for no one to go looking for him. He made up the story that his parent had died and that he know lived with his aunt. He changed a few of his features with the same charm Hermione used when they broke into gringots on Ron. He died his hair a few shades lighter and started wearing contacts and not his glasses. He took the first name Peter, and Mays last name, Parker. Still looking surprisingly youthful, he decided to go to muggle high school and live in a world his name wasn’t famous. Of course, the world being out to get him, he had to get bitten by a radioactive spider, and became Spiderman. This caused the avengers to take interest in him. They recruited him, and he became an avenger. They became a family, and Harry, well now Peter told them about his past. They obvious accepted it, but they never talked about it much or went into any details.
