The protagonist of Pokémon Black and White is Hilbert and Hilda, who journeys through Unova to become the Pokémon master. At the beginning of the games, the player chooses either Snivy, Tepig or Oshawott as their starter Pokémon as a gift from Professor Juniper. The protagonist's friends, Cheren and Bianca, are also rival Pokémon Trainers who occasionally battle the player; Cheren will choose the Pokémon with a type advantage against the player's, while Bianca will choose the Pokémon with a type disadvantage. The player's primary goal is to obtain the eight Gym Badges of Unova and ultimately challenge the Elite Four of the Pokémon League, and its Champion, to complete the main story.
There are three basic screens: an overworld, in which the player navigates the main character; a battle screen; and the menu, in which the player configures their party, items, or gameplay settings. The player controls a Pokémon Trainer who begins the game with a single Pokémon and is able to capture more using Poké Balls. Like all other Trainers, the player can carry up to six Pokémon at one time. However, the game also includes a network of PCs to store hundreds of Pokémon. PCs are found in certain buildings—named, "Pokémon Centers", where the player can heal their Pokémon when they have low health or have fainted.
