'Young Justice: Outsiders' made Darkseid and the Light's plans clearer but Metron still a wild card come Season 4
While Metron hasn't actually shown any villainous tendencies, his cold calculating manner makes him an extremely unpredictable player in the war to come
When 'Young Justice' returns for its fourth season, the show's young heroes will be fighting battles on two fronts, countering the Light's machinations on Earth while also trying to stop Darkseid's plans for the cosmos at large. But these two are merely the enemies the Team knows about and the threats they are unaware of may prove to be their undoing.
After the events of the third season, 'Young Justice: Outsiders', we now have a fair idea of what Vandal Savage and the Light have planned for the Earth. The Light wants humanity to ascend the evolutionary ladder and help the Earth become a cosmic superpower.
The impending war with Darkseid is really just a small part of Savage's grand design for the universe, one that the Light hopes to manipulate for their own interests. Meanwhile, Darkseid has been quite straightforward about his goals: conquest, devastation and, most importantly, the subjugation of all living things using the Anti-Life Equation.
If the Light's designs go forward as planned, the universe could face large-scale devastation in an all-out war between Apokolips and the Earth. But while we do know about the two prominent villains, the New God Metron continues to be a wild card.
Unlike the rest of his compatriots, the creator of the Mother Boxes and Father Boxes has no desire to pick sides in the conflict between good and evil, choosing instead to spectate and analyze the actions of both sides. In Episode 25 of 'Young Justice: Outsiders', Metron revealed that the heroes Victor Stone/Cyborg (Zeno Robinson) and Violet/Halo (Zehra Fazal) are technically his grandchildren because they were "born" of a Father Box and a Mother Box respectively.
The brief scene also suggests he may have a certain degree of control over the heroes because of his connection to the technology that powers them. If he were to turn either of the heroes against their friends, there's no telling what damage he can do considering the near-limitless power the both of them have access to.
While Metron hasn't actually shown any villainous tendencies, his cold calculating manner makes him an extremely unpredictable player in the war to come. Though there is a chance he may provide some invaluable assistance against Darkseid and the Light, it seems far more likely that he may cause more harm than good to our young heroes.
'Young Justice: Outsiders' is currently available for streaming on DC Universe. 'Young Justice' Season 4 was announced during San Diego Comic-Con 2019 but a release date is yet to be revealed. Fans of the show can expect the next season to arrive on the service sometime in 2020.
