The Spider Universe

  Details about "Spider-Man 4" with Tom Holland have been sparse and primarily speculative. Here are a couple of theories and ideas that could shape the next installment if it follows the trends of previous films and comic book lore:

1. **New Villains**: Each "Spider-Man" film tends to introduce new villains. Given the multiverse theme in "Spider-Man: No Way Home," we might see a continuation with threats from different dimensions, possibly setting the stage for villains like Kraven the Hunter or even a return of characters like Venom.

2. **The Sinister Six**: There's long been speculation and desire from fans to see the Sinister Six, a team of villains, come to life on the big screen. Elements from previous films could converge to finally make this a reality, perhaps with some members already introduced in earlier movies.

3. **Spider-Verse Expansion**: The multiverse concept opens doors to different Spider-People across dimensions. There’s potential for live-action adaptations featuring characters from the animated "Spider-Man: Into the Spider-Verse" like Miles Morales or Gwen Stacy's Spider-Woman. 

4. **Peter Parker's Personal Growth**: The next movie might focus on Peter's evolution now that his identity has been forgotten by the world. This might lead to a matured Spider-Man who operates differently, developing new relationships and potentially taking on a mentor role, similar to Tony Stark for him.

5. **Daredevil and Street-Level Heroes**: With the appearance of Matt Murdock in "No Way Home," there's a possible setup for more grounded, street-level hero interactions. Spider-Man could team up with Daredevil or encounter other heroes like Jessica Jones or Luke Cage from the Defenders.

6. **Introduction of Oscorp**: There’s room to introduce Oscorp, which has not been prominently featured in the Holland Spider-Man films. Norman Osborn could be a significant figure in the upcoming films, expanding the scope of Peter's challenges beyond physical threats to corporate and political intrigue.

7. **Continued Fallout from "No Way Home"**: There could be further exploration of the consequences of the multiverse breaches and the spells cast by Doctor Strange, which could lead to otherworldly conflicts or realities colliding.

8. **Crossover with Fantastic Four or X-Men**: With Marvel's acquisition of Fox, the inclusion of the Fantastic Four or X-Men in the MCU is imminent. Spider-Man could play a role in introducing these characters, strengthening the interconnectedness of the MCU.

9. **Advanced Tech and the Iron Spider Suit**: Holland's Spider-Man has heavily used Tony Stark's technology. In the next installment, Peter may develop his tech abilities further, maybe creating a new suit or gadgets that enhance his abilities in unique ways.

Remember, these are just theories and should be considered speculative until confirmed by official sources. The actual direction Marvel Studios and Sony take with "Spider-Man 4" may be entirely different. Aside from the Multiverse, Marvel could take a quick step and bring SONY'S Spiderman Beyond The SpiderVerse in the future as in No Way Home Electro mentioned there must be a black spiderman out there of course referring to Miles Morales and we also get a preview of Miles's Uncle, Aaron Davis in SpiderMan Homecoming.
