Though we've covered all the canon events depicted or mentioned within "Spider-Man: Across the Spider-Verse," we believe a few Spidey moments could be potentially classified as such in the near future. The clearest of these would be the occurrence of a chance multiversal encounter which, as of "Spider-Man: No Way Home," every Spider-Person has seemingly experienced at some point or another. If that doesn't constitute a canon event, we don't know what does.
Similar to the feat of strength in "If This Be My Destiny," another canon event could be a Spider-Person using bundles of their own webs to hold onto something and/or hold it together. The Spider-Man of Earth-96283 ("Spider-Man 2") did this to stop a runaway train, while the Spider-Man of Earth-199999 ("Spider-Man: Homecoming") did it to stop a ferry from breaking in two.
Lastly, as jokingly acknowledged by Ned Leeds (Jacob Batalon) in "No Way Home," most Spider-People are unfortunately betrayed by a close friend who turns into a supervillain. This was true for the variants on Earth-65 (Peter Parker, as seen in the "Spider-Verse" films), Earth-96283 (Harry Osborn in "Spider-Man 3"), and Earth-120703 (Harry Osborn, again, in "The Amazing Spider-Man 2"). Given how important canon events seem to be to the future of the multiverse, we'll likely learn much more about them when "Spider-Man: Beyond the Spider-Verse" swings into theaters next year.
