WARNING: The following article contains spoilers for Sony's Spider-Man: Into the Spider-Verse, in theaters now.
At the end of Spider-Man: Into the Spider-Verse, Miles Morales and his team of Spider-heroes stop Wilson Fisk's particle collider from destroying the multiverse. The teen's allies return to their respective dimensions and he accepts that he has what it takes to succeed the dead Peter Parker as Spider-Man.
That's obviously not the last audiences will see of Miles & Co., as Sony has already confirmed plans for a sequel and a spinoff. But we don't have to look far to discover clues to where the franchise might be headed; Into the Spider-Verse offers plenty of clues.
For starters, the post-credits scene introduces Miguel O'Hara (Oscar Isaac), better known as Spider-Man 2099, monitoring the events of the film alongside his holographic assistant Lyla (Greta Lee). They've been keeping an eye on the multiverse, but Miguel decides it's time to make a reality-jumping journey of his own.
He first heads to Earth-67, the world of the 1967 Spider-Man animated series, or as he calls it, "the very beginning." He parodies that famous meme of Spider-Man pointing at his double, and even runs afoul of J. Jonah Jameson, but as he hints to Lyla, he's searching for something important.
In the comics, Miguel was forced by his unethical Alchemax boss, Tyler Stone, to take a drug, which led to Miguel accidentally splicing his DNA with that of a spider, imbuing him with abilities similar to those of the original Spider-Man. When Miles was bitten in Into the Spider-Verse, it was by a spider branded with Alchemax's logo. However, the arachnid doesn't seem to be from his universe, as it phased in and out of reality when he swatted it. That hints the spider is from another universe, quite possibly Miguel's, and he's actually tracking it. That paves the way for him to recruit Miles as a partner and act as another experienced mentor to the teen.
When Kingpin first operated the collider, there's a chance more than one of these spiders was sucked into Miles' reality -- or, worse still, was hurled across the universe. The spider was also labeled as "42," which indicated it's the 42nd of its kind. If that's the case, then Miguel is going to need help, not just to scour Miles' reality, but also to possibly take down Alchemax in his own world.
If Miguel also has to track down several of these Alchemax spiders across the multiverse, then a sequel could also follow him and Miles reuniting with some of the old crew. We know the planned sequel will focus on the budding relationship between Miles (Shameik Moore) and and Gwen Stacy (Hailee Steinfeld), and that a spinoff will introduce the Spider-heroes Silk and Jessica Drew, so either premise could easily work in concert with a search for rogue spiders.
Coincidentally, as the movie ends and Miles is falling asleep, we hear Gwen's voice contacting him to ask whether he's "got a minute." She's already depicted as a genius, so there's also the possibility she too developed technology that could breach dimensions and create less-dangerous rifts. Miles could always return the favor and head over to her world to help her out in times of need, especially as they already struck up a romantic bond at Brooklyn High.
Last but not least, right in Miles' own dimension, he's already making enemies. He webbed up the Kingpin for the police to take in, and they locked up Tombstone and Olivia Octavius, aka Doctor Octopus. However, Norman Osborn, in the gigantic form of the Green Goblin, is still on the loose, which sets up a potential feud with Miles. Also, seeing as he's already on the hit list for all of the rogues left behind by his Peter Parker. you can't rule out a new Sinister Six forming to take down the young hero. Kingpin, for one, might not know his identity, but from battle, he knows the new Spider-Man is a teen, which could lead to a target being painted on Miles' back.
