Power Ring/Red

Red power rings are powered by rage, feed on the rage of their users and anyone nearby, and are charged by the blood of those the user kills. Unlike Green Lantern rings, which provide a helpful commentary to their user, red rings are depicted as constantly emitting violent commands ("Kill," "Rage," "Pain," "Hatred," etc.), driving their wearers insane with rage and reducing them to little more than snarling beasts. The rings, however, seek out beings with great rage. A user's red ring functionally replaces the user's heart, tainting their blood with red energy, and forces it out of their body through their mouth as a highly corrosive substance. The red ring's energy is also capable of corrupting the energies of other power rings, keeping them from functioning properly. The aura of a red ring is savage and rough in comparison to a green ring, but can be used similarly with sufficient focus.
