From Bulbapedia, the community-driven Pokémon encyclopedia.
Jeeves is a recurring character in the Pokémon anime. He was unnamed in the Japanese version. Jeeves appears to be Madame Muchmoney's butler. His Japanese voice actor is 宇垣秀成 Hidenari Ugaki.
Jeeves first appeared in Snubbull Snobbery. He was seen serving Madame Muchmoney's Snubbull, but the Normal-type Pokémon rejected him.
He then appeared again in The Trouble with Snubbull. Along with Madame Muchmoney, they were trying to locate Snubbull and bring it back to the mansion. By the time they found it, it had evolved into Granbull. Eventually, Jeeves and Madame convinced Granbull to return.
