The Red Lantern Corps are enemies of the Green Lantern Corps, Sinestro Corps and Blue Lantern Corps. Officers are given a power ring fueled by the strength of their hate. Every Red Lantern character in Scribblenauts Unmasked can summon objects made of red hate to fight. They can also fly. They fight good.
Warning: This list is incomplete.
All Lanterns are powered by the Power Rings, and Red Lanterns are powered by the Red Lantern Power Ring.
