9. Another Corps
DC ComicsThere are eight other Corps, in addition to the Green Lanterns, in DC Comics. While the Green Lanterns are fuelled by willpower, there are also Yellow Lanterns (AKA the Sinestro Corps) who are fuelled by fear, the Red Lanterns who are fuelled by rage, the Blue Lanterns who are fuelled by hope, the Indigo Tribe who are fuelled by compassion, the Star Sapphires who are fuelled by love, Agent Orange who is a Corps unto himself and is fuelled by avarice, the Black Lanterns who are composed of dead characters and the White Lanterns who draw upon the power of life itself. While not all of these Corps are direct rivals to the Green Lanterns - indeed some of them are allies (the Blue Lanterns, for example, are friends of the Green Lanterns and are more powerful in the presence of a Green Lantern character) - it would be cool to see new Corps' emerge in a live action movie and have them attack the Green Lanterns. Seeing a horde of Red Lanterns, for example, or Agent Orange with an army of constructs, trying to destroy the Green Lanterns would be awesome and would acknowledge the fact that other Corps' exist in the DC Cinematic Universe, which could potentially lead in to a whole number of other great stories in the future.
