The first three seasons of Young Justice are available on DC Universe.
During the DC FanDome, at the virtual Young Justice panel, series executive producers Greg Weisman and Brandon Vietti announced that season 4 of the animated series will have a new title: Young Justice: Phantoms.
Aside from this news, the panel also featured Weisman, EP Brandon Vietti, and cast members Khary Payton, Nolan North, Danica McKellar, Crispin Freeman, Stephy Lems, and Denise Boutte performing a new "canon to the series" audio play that's set between Season 3 and 4 called "The Prize." Written by Weisman, the play provides an early glimpse into the new season by setting up events that eventually play out further in Young Justice: Phantoms.
Young Justice: Phantoms is executive produced by Weisman and Vietti along with Sam Register (Teen Titans GO!). Produced by Warner Bros. Animation, the first three seasons of Young Justice are available on DC Universe.
The series follows teenage superheros trying to prove themselves as members of the Justice League including Robin, Aqualad, Cyborg, Kid Flash, Superboy, Artemis Crock and many more.
