Calem

Calem is one of Red's potential roommates. He is incredibly studious and diligent, due to the fact that he comes from a family of professional Pokémon trainers. He has a relatively quiet ongoing feud with his next-door neighbor and childhood friend Serena, which Red will find himself trapped in between should he attempt to get involved.

Calem was first introduced in Pokémon X and Pokémon Y versions.
