The oath required to recharge Larfleeze's ring has not been heard despite rumors of it being the word "mine" (a demand regularly made by both Agent Orange and his Orange Lanterns).
An orange ring is powered by avarice. According to Ganthet, "the orange light of avarice will be discovered and manipulated by a being whose greed knows no bounds." Unlike the other Corps, Larfleeze (primarily known as "Agent Orange") is the only individual to wield the power of the orange light. The story of how he came to be the sole owner of the orange power battery is detailed in the Agent Orange story-arc running from Green Lantern (vol. 4) #39-42 (April-July 2009). The Guardians of the Universe are described as making an agreement with Larfleeze long ago in return for a box containing the fear entity: Parallax. The agreement allows him exclusive control of the orange light with the condition that he remain in the Vega system. During the Agent Orange arc, Larfleeze attracts the attention of the Guardians again through an act of terrorism prompted by an intrusion from the Controllers on his home planet, Okaara. A Green Lantern force confronts him, and (after being unable to decide between releasing him and destroying him) create another deal with him at the expense of the Blue Lanterns.
Even alone, Larfleeze is a formidable opponent for the Green Lantern Corps. The power of the orange light allows Larfleeze to steal the identities of those he kills, transforming them into an Orange Lantern construct. By being in constant contact with his main power battery, Larfleeze has become one with his power source. This allows him to maintain a power level high enough to support an entire Corps of orange light constructs even when separated from it. The orange light does have a severe drawback: whoever wields it is in a constant state of hunger, unable to be satiated or to rest. Larfleeze and his constructs are shown to be resistant to magic and the abilities of green power rings, but do not retain the same protection against blue or violet rings.
