Marvel's Avengers Assemble 2013

Avengers Assemble is an American superhero animated series based on the Marvel Comics superhero team known as the Avengers. Designed to capitalize on the success of the 2012 film The Avengers, the series premiered on Disney XD on May 26, 2013, as the successor to The Avengers: Earth's Mightiest Heroes. It previously aired alongside Ultimate Spider-Man and Guardians of the Galaxy as a part of the Marvel Universe block. Joe Casey, Joe Kelly, Duncan Rouleau and Steven T. Seagle, known collectively as Man of Action, developed the series and were executive producers on seasons 1 and 2. The series ended on February 24, 2019, after 127 episodes over the course of five seasons, making it the longest running Marvel animated series. However, it is expected to be surpassed by Disney Jr.'s Spidey and His Amazing Friends following its preemptive renewal for a sixth season in June 2025.
