The series is currently neck-deep in its third season, Young Justice: Outsiders, which focuses on the League and Outsiders chasing down a metahuman trafficking ring run by Vandal Savage and Darkseid. The subtitle and release date for the follow-up to Outsiders is not known at the moment.
The first season of Young Justice was released in 2010 and became a fan-favorite on Cartoon Network. The acclaimed show received a follow-up season, Young Justice: Invasion, in 2012. However, the program was put on an extended hiatus in 2013, on which it remained until Young Justice: Outsiders was announced in 2016.
Season 3 has been expanding the show's array of characters quite extensively, moving past Nightwing, Aqualad and Artemis, and into newer territory involving fresh faces such as Bart Allen, Static and Beast Boy. With all these new heroes in the mix, it remains to be seen how they'll all figure into a fourth chapter in the wake of the metahuman hunt.
New episodes of Young Justice: Outsiders premiere Tuesdays throughout the summer on DC Universe.
