Avengers: Secret Wars is expected to bring together all the current active heroes in the Marvel Cinematic Universe, making it the perfect opportunity for Spider-Man to finally meet two of the original Avengers. Despite being one of the most popular and beloved characters from Marvel Comics, it took a couple of years for Spider-Man to be officially introduced in the MCU. Tom Holland’s Spider-Man made his debut in Captain America: Civil War before starring in his first solo movie, Spider-Man: Homecoming, so the MCU skipped his origin story.
