It seems the focus on the next season of Young Justice will bring the focus back to the original core team (minus Wally) as the first poster for Young Justice: Phantoms was released. The show will have a significant presence during the online DC FanDome event on October 16.
In an interview with Collider, series creators Brandon Vietti and Greg Weisman revealed that the upcoming season will focus on individual characters instead of having storylines focused on specific teams, i.e. the Justice League, Young Justice, Outsiders, etc.
Said Weisman, "This season focuses more on individual character dynamics than on League/Team/Outsiders politics. But we will see a bit of each of these squads (among others), and covert action is always an important part of the Young Justice dynamic."
First announced during San Diego Comic-Con 2019, Young Justice fans have waited patiently for news on the fourth season's storyline and release date. It now appears that they'll have answers this Saturday as Weisman took to Twitter to tease that YJ fans definitely don't want to miss DC FanDome.
