Orange Power Rings are malevolent rings found in the Green Lantern franchise, they are part of the malicious spectrum of Power Rings that also include Yellow Power Rings (fear), Black Power Rings (death) and Red Power Rings (rage).
An Orange Power ring is powered by avarice, or greed. There is only one true member of the Orange Lanterns, Larfleeze. All other "members" are only constructs of Larfleeze 's power ring. Each member is actually the projected spirit of a being Larfleeze has killed before. The ring can create constructs based on the wielders own thoughts, produce energy blasts, generate force fields, absorb the constructs of other ring wielders, render the wearer invisible, allow them to phase, fly, absorb energy, translate languages, create spacial warps and even regenerate health in a limited way.
