When it seems victory is in their grasp, Black Panther steps up to recruit Vision, Captain Marvel, Ms. Marvel, Ant-Man and the Wasp to stand in the Avengers' place. What follows is a knock-out, drag-out fight where only one team can walk away the winner.

A series of six animated shorts aired June 2 on Disney XD, introducing viewers to the powers of the New Avengers in flashback sequences.

In an interview with CBR, Marvel Animation Vice President Stephen Wacker revealed what audiences can expect from Avengers: Secret Wars. “We will see Battleworld,” he said. “Much like this season, we will see a collection of stories that at first might seem like standalone adventures that we come to realize are all related to each other. We kick off the season with a focus on our new characters, including Ms. Marvel, Captain Marvel, Black Panther, Vision, Ant-Man and Wasp, and they become very important as the season goes on.”

Avengers: Secret Wars debuts with a one-hour premiere Saturday, June 17, at 11:30 a.m. ET/PT on Disney XD.
