Justice League x RWBY: Super Heroes & Huntsmen, Part One (2023) on Netflix

Plot summary

Clark Kent comes to in the Emerald Forest near Beacon Academy, where Ruby Rose and Yang Xiao Long battle a pack of Grimm. The semblance he has gained here depends on sunlight, leaving him weaker than on Earth. The sisters notice the Grimm absorbing dust and firing lasers. In Menagerie, Blake Belladonna meets Diana Prince, and in Atlas, Weiss Schnee meets Bruce Wayne, who now has bat faunus traits and a semblance of his own. At the academy, the group finds Jaune Arc, Nora Valkyrie, Lie Ren, Mari McCabe, Victor Stone, Barry Allen and Jessica Cruz. The Justice League members have become teenagers, and their powers are diminished: Barry Allen is slower, Victor Stone's technology matches this world's era, and Mari McCabe and Jessica Cruz have neither the totem necklace nor the ring that grant their powers.
