At the 2011 San Diego Comic Con, The Avengers were confirmed as guest-stars on "Ultimate Spider-Man", including Iron Man, Thor, Captain America, and The Incredible Hulk. This will be the first time that Spider-Man has teamed on-screen with The Avengers in an animated series (since 2010's The Avengers: Earth's Mightiest Heroes) and the first time Spider-Man and the Hulk have been on the same animated series since 1981's "Spider-Man and His Amazing Friends".
