In Black and White, Hilda 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, she has a 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.
She appears to wear a white cap with a red Pokéball printed on it and a red visor. She has shaggy brown hair, blue-tinted eyes, and pale skin. She wears a black vest jacket over her sleeveless white t-shirt, short tight jeans, black converse boots with red laces and red tread, and black socks. She carries a red satchel.
