Spiderman--

Not all of the script follows canon, so be careful.
*Peter Parker was a seventeen-year-old teenager hiding behind the mask of Spider-Man. When ALL of New York learned of this, the majority of the city reacted negatively due to the assumption that Peter (Spider-Man) killed Mysterio and stole the drones from Tony Stark. For everyone, it was a logical option, but no one knew the real truth. All this negativity took a toll on Peter; he was extremely tired, and one time, a brick wrapped in newspaper with the words "For Mysterio!" was thrown through his window. Of course, there were people nearby who supported Peter, such as Ned, MJ, his Aunt May, and Happy. But there was someone else... Deadpool. After some time, a whole paradox occurred: MJ and Ned, using the ring of "Sorcerer," as Tony called him, summoned two Spider-Men from two other universes. Because somehow, Doctor Octavius, Doctor Osborn, Sandman, and Electro ended up in Peter's universe. MJ and Ned summoned the two spiders completely by accident while looking for THEIR Peter.

So, 24 hours later, it turned out that absolutely everyone had forgotten Peter. All of New York. Everyone who could, everyone who had ever supported him. And the X-Men caught Deadpool and committed him to a mental hospital.
(You are Deadpool).
