Many fans were excited to learn that Robert Downey, Jr. would be reprising his role as Tony Stark in Spider-Man: Homecoming, especially when he popped up in the film's first trailer. Iron Man won't be returning, however, but Sony is planning to add a different Marvel hero to guest-star alongside Tom Holland for Spidey's next headlining adventure.

In a profile of new Sony CEO Tom Rothman that explores the studio’s relationship with Marvel Studios, The Hollywood Reporter reveals that Iron Man won't return for the already announced sequel to Spider-Man: Homecoming. No clues are given as to which Marvel character could appear, but with a large number of heroes currently occupying the Marvel Cinematic Universe, we could see the likes of Captain America, the Hulk, or even a new hero entirely team-up with Holland's Spider-Man to take on a new threat.

A young Peter Parker/Spider-Man (Tom Holland), who made his sensational debut in Captain America: Civil War, begins to navigate his newfound identity as the web-slinging super hero in Spider-Man: Homecoming. Thrilled by his experience with the Avengers, Peter returns home, where he lives with his Aunt May (Marisa Tomei), under the watchful eye of his new mentor Tony Stark (Robert Downey, Jr.). Peter tries to fall back into his normal daily routine – distracted by thoughts of proving himself to be more than just your friendly neighborhood Spider-Man – but when the Vulture (Michael Keaton) emerges as a new villain, everything that Peter holds most important will be threatened.

Swinging into theaters July 7, director Jon Watts’ Spider-Man: Homecoming stars Tom Holland, Donald Glover, Jacob Batalon, Laura Harrier, Tony Revolori, Tyne Daly, Bokeem Woodbine, Marisa Tomei and Robert Downey Jr.
