In Black and White, Hilbert travels the Unova region to complete a Pokémon journey, to defeat gyms left and right, defeat the Elite Four, and become a Pokémon master. At the beginning of the game, he has the choice to pick one starter Pokémon from Professor Juniper, out of three: Snivy, the grass-type; Tepig, the fire-type; and Oshawott, the water-type.
He appears to wear a red and white cap with a black Pokéball printed on it and a black visor. He has shaggy brown hair, gray-tinted eyes, and pale skin. He wears a various-hued blue sweater, dark gray baggy pants, and red kicks. His bag has a gray base with matching gray straps, and its flap is blue with a white border.
