Arbiter-Eclipse is a being formed from Eclipse merging with the body of Arbiter (Causing Arbiter's mind and soul to exist as a separate entity). The combination of Arbiter's and Eclipse's powers have made Eclispe unimaginably powerful, granting him the ability to spread his influence across virtually every realm that exists, as well as granting him control of both Balance and Imbalance (The antithesis of Balance).
