Who Will Be the Villain in Spider-Man 4? These 3 Theories Are So Convincing

Those who waited in the theatre to see the midcredits scene of Spider-Man: No Way Home know Eddie Brock (Tom Hardy) and Venom are briefly transported into Peter Parker's (Tom Holland's) universe after Doctor Strange's (Benedict Cumberbatch's) spell. This opens up the possibility of Venom entering the MCU even though Venom is technically not an MCU franchise.

The postcredit scene of Venom: Let There Be Carnage also backs up the idea that Eddie and Venom could star as villains in Spider-Man 4. In it, Eddie and Venom are watching TV in a tropical hotel room and see the news broadcast that Peter Parker is Spider-Man. Venom then remembers his encounters with him in previous comics and movies (he's an all-knowing interdimensional being, after all).

In a September interview with IGN, Venom director Andy Serkis foreshadowed a future meeting between Venom and Spider-Man. Based on this foreshadowing, Giant Freakin Robot further theorized "a different symbiote character named Toxin could overtake Eddie Brock and force Venom to go on a villainous tirade targeting Spider-Man."

Spider-Man 4 won't be for a while, but with both ending credit scenes from Let There Be Carnage and No Way Home indicating a connection, most signs point to a crossover.

Another theory suggests that No Way Home lays the groundwork for Ned Leeds (Jacob Batalon) to become the Hobgoblin at some point in the future.

Ned's ability to use Strange's ring and open portals on his own could point to his magical potential. And when Ned asks Tobey Maguire's Peter Parker if he ever had a best friend while the gang are formulating cures in the high school science classroom, Peter says yes, but that he turned evil, tried to kill him, and ultimately died in his arms. Ned promises Peter Parker he'll never turn evil and try to kill him, but it almost seems like he's apologising in advance if anything should happen between them. It should be noted that Ned ultimately forgets the promise he made to Peter because of Doctor Strange's second spell making the entire universe forget Peter's existence.

Though it's unclear whether Ned will become Hobgoblin in Spider-Man 4, fans see the developments in No Way Home as laying the groundwork for Ned to take up the mantle somewhere down the line.

True fans of Marvel know Flash Thompson (Tony Revolori) is more than just Peter Parker's high school bully like how he's portrayed in movies like Spider-Man: Homecoming, Far From Home, and No Way Home. In the comics, Flash eventually bonds with Venom symbiote and becomes Agent Venom.

Peter and Flash have an established rivalry in the Marvel comics, and that rivalry, while less developed and very different, certainly exists in the MCU. So considering Eddie Brock left behind some symbiote when he was magicked back into his universe by Doctor Strange's second spell, it's possible his fate in the Marvel comics could play out on screen. Knowing Venom and Spider-Man will cross paths in the near future, it makes sense to consider Flash as another MCU side character to battle Peter in upcoming movies like Spider-Man 4.
