Superman, Batman, Wonder Woman, Flash, Cyborg, Green Lantern and Vixen are transported to the strange world of Remnant and find themselves turned into teenagers. Meanwhile, Remnant heroes Ruby, Weiss, Blake and Yang must combine forces with the Justice League to uncover why their planet has been mysteriously altered before a superpowered Grimm destroys everything.

When a small Bean challenges the mighty warrior Naiwag to a duel, her reluctant best friend Beetle must help her train to become a powerful knight.

The future-fantasy world of Remnant is filled with ravenous monsters, treacherous terrain, and more villains than you can shake a sniper-scythe at. Fortunately, Beacon Academy is training Huntsmen and Huntresses to battle the evils of the world, and Ruby, Weiss, Blake, and Yang are ready for their first day of class.
