Greevil
From Bulbapedia, the community-driven Pokémon encyclopedia.
Warning: Spoilers follow.
Although it seemed that [Evice] was the head of [Cipher], that was not the case. Evice was simply following the orders of the true head of the organisation: Master Greevil. Greevil then proceeded to go under the guise of a man named Mr Verich, and won the favour of Gateon Port by providing free food and drink. From his HQ on Citidark Isle, Greevil created [XD001], the Shadow Lugia. However, he was defeated by the hero of Pokemon XD.
