The Avarice entity is greed incarnate with all of avarice's power at its disposal. One must 'Want it all' to wield the Orange Light. Those who wield the Orange Light are infected by the light's insatiable appetite for anything and everything. Other than Lex Luthor, all the other members of the Orange Lantern Corps are orange energy constructs of those slain by the Orange Light and reborn as Orange Lanterns whose former selves have been perverted by the avarice light. Larfleeze, the only living member of the Orange Lantern Corps.
The Orange Lantern Corps wields the power of avarice and is led by Agent Orange, a.k.a. It entices and lures its wielder into coveting the battery more than anything else in existence, even life itself. For the majority of its existence, the Avarice Entity has been sealed within the Orange Lantern Central Power Battery.
