Cheren

Cheren is one of Red's potential roommates and later becomes the student council president. He is a strong-willed individual bound by rules and logic. Because of his personality, Cheren can often be crass and difficult to deal with, even though he's at his toughest when he means well. He is longtime friends with Hilbert, Hilda and Bianca.

Cheren was first introduced in Pokémon Black and Pokémon White versions.
