Wu Zhang (also known as Mao Fanchu or most commonly Cypher) is the father of Wing Fanchu and a former member of the G.L.O.V.E ruling council. He assisted in the making of Overlord. He was believed to be dead at the hands of Overlord,so he wore a glass mask to conceal his true identity. At the end of The Overlord Protocol he was unmasked and presumed dead. In Rogue, Cypher returned and tried to stop Wing from coming to H.I.V.E again and tried to shoot the animus infected Otto before Wing intervened by shooting his father.
