History Film / SpiderManNoWayHome

** Peter tries to erase the world's knowledge of his secret identity through Strange's magic... only for him to suddenly realize this would affect his loved ones as well. He attempts to modify the spell multiple times to avoid this, his last modification (when the spell's already obviously going catastrophically haywire) being "Basically everyone who knew [that Peter was Spider-Man] before should still know!" The resulting botched spell ends up ''pulling in some people from TheMultiverse'' who "[[ExactWords knows Peter Parker is Spider-Man]]" into the MCU. Doctor Strange even says this verbatim to him when he first begins seeing the effects of the spell going sideways.

** This film retroactively establishes that Norman Osborn and Otto Octavius were acquainted with each other in their original continuity, Amusingly, despite an earlier scene of Octavius expressing confusion about the Peter native to the MCU and it being established he knew his universe's Curt Connors, neither he, [[spoiler:nor the Peter he and Norman dealt with,]] express confusion about the Connors of ''Film/TheAmazingSpiderManSeries'' being a British, lizard monster.

* ConnectedAllAlong: This film retroactively establishes that Norman Osborn and Otto Octavius were acquainted with each other in their original continuity, as were Curt Connors and Max Dillon. Amusingly, despite an earlier scene of Octavius expressing confusion about the Peter native to the MCU and it being established he knew his universe's Curt Connors, neither he, [[spoiler:nor the Peter he and Norman dealt with,]] express confusion about the Connors of ''Film/TheAmazingSpiderManSeries'' being a British, lizard monster, nor do the Connors and Dillon of that universe, who works for their universe's Oscorp (and in Connors' case, given the nature of his work, probably knew their Norman Osborn personally) [[spoiler:or even ''their'' Peter Parker, whose father works with Connors and Osborn,]] express confusion about the ''Film/SpiderManTrilogy'' Green Goblin not looking like their Osborn.

* CanonWelding: This movie reintroduces characters from the ''Film/SpiderManTrilogy'' by Creator/Sam Raimi and ''Film/TheAmazingSpiderManSeries'' by Marc Webb and establishes this movies' continuities as canon within the wider multiverse of the MCU. TheStinger also shows [[spoiler:Creator/TomHardy's Film/{{Venom|2018}} briefly stranded in the MCU, also confirming that Film/SonysSpiderManUniverse is also part of said multiverse]].

* AnAesop:
** The harder you try to hold onto the past, the faster it will slip through your fingers, as symbolized by Peter's last-second desperation to have, at least, his loved ones remember his identity as Spider-Man [[spoiler:eventually resulting in the death of May and '''nobody''' remembering him, ''period'']].
** Learning to forgive, particularly yourself, is necessary to move on and start a new life. The Raimi-verse and Webb-verse Spider-Men were fortunate enough to learn this; it remains to be seen how long it will take for MCU Peter to move on from and forgive himself for the still-fresh guilt of [[spoiler:being directly responsible for Aunt May's death]].
** Sometimes [[NoGoodDeedGoesUnpunished the world will reward your charity with suffering]], but that doesn't mean you should stop trying.
** Just talking to someone, even if it seems like they've made up their mind, can be effective -- and is certainly safer than attempting to inflict LaserGuidedAmnesia on the world.

->''"We learned new things. We traveled the world. We fell in love. We almost died, multiple times. We made friendships that will last forever. Also, [[Film/AvengersInfinityWar some of us disappeared for five years]] [[Film/AvengersEndgame and then reappeared]], but the less we talk about that, the better. What's important is that we made it. And as we look out onto an exciting and uncertain future, just remember: the memories that we've made here at Midtown High are the ones that we will cherish forever. That's Midtown News for today, and for one last time, this has been Betty Brant, signing off."''

** After being depowered and receiving a pep talk from his Spider-Man, Max Dillon admits that he assumed his Peter (a working-class hero from Queens) would be black, and further wonders aloud that there must be a [[Characters/UltimateSpiderManMilesMorales black Spider-Man]] out there in the multiverse.

* MistakenEthnicity: Electro admits to Webb-verse Peter that he always thought he was black, and initially seems a little disappointed to learn otherwise (to which Peter actually apologizes). He gets over it, musing that with the multiverse there probably still ''is'' [[Characters/UltimateSpiderManMilesMorales a black Spider-Man out there]].

* LetsYouAndHimFight: Upon seeing each other, the Raimi-verse and Webb-verse Peters have a very brief spat where they shoot their webs at each other, ending with Raimi-verse Spider-Man webbing up one of Webb-verse Spider-Man's web shooters.

* SequeiAdaptationIconicVillain: After Peter fought Vulture and Mysterio in the previous two films, he faces off against some of the villains of the previous movies - including the Green Goblin and Doctor Octopus, his two [[ArchEnemy Arch-Enemies]] in the comics.
