In 2020, DCEU will make a film called Green Lantern Corps, featuring both Hal Jordan and John Stewart. But now, i'm going to discuss about the film's main villain. In my opinion, I think they better make Red Lantern Corps as the main villain. I hope they will feature some Red Lanterns like Atrocitus, Zilius Zox, etc. I think the Red Lantern Corps should be a bad corps and they will attack and threaten the Green Lantern Corps so maybe Hal Jordan will help the Green Lantern Corps. Maybe Hal Jordan will be having a hard time to battle Atrocitus while the other Green Lanterns will help him battling the rest of the Red Lanterns.
