so basically Spider Man killed Mysterio, and Mysterio revealed Spider Man's identity as Peter Parker before Mysterio dies, but because of that he was seen as the bad guy because they see Mysterio as a hero while he uses drones to imitate fake monsters that does real life damage, and so, Spider Man goes to see Doctor Strange, a fellow avengers to wipe everyone's memory of him ( doesnt include the people who knows him before he killed Mysterio ), but the spell quickly turned dangerous so Doctor Strange locked all the spell inside a tiny box, after that Spider Man went to a high way to meet with a person that can help spider man so that his friends that are connected to him can be received to MIT, there, he encountered Doctor Octopus, who came from a different universe, he fights with Doctor Octopus and managed to take control of Doctor Octopus's tentacles, then appeared Green Goblin, who almost hit Spider Man with his glider but Doctor Strange Saves Him using a magic portal and locks up Doctor Octopus in an invisible barrier, along with Green Lizard whom Doctor Strange encountered in the sewers ( all of the villain in this movie are all from different universes than peter, but some villains recognize the other villain and are from the same universe, annnnnnd i dont even wanna explain more, too complicated
