Judge R was a member of the Judges who recruited people for G.O.H Tournament. He was the one to recruit Jin Mo-Ri for the tournament. He then revealed himself to have betrayed Park Mu-Bong and defected from the Judges, becoming a Bishop of the organization Nox under the new alias Ultio R. This was supposed to be a ploy to destroy Nox from the inside, but R double-crossed both Mu-Bong and The King in order to become the new emperor, revealing himself to be a part of the first experiment of the king, one the latter deemed a failure.
