Pocket Monsters stars a Pokémon Trainer named Red and his rude Clefairy. It is chiefly a gag manga, using crude humor and slapstick.
The series diverges somewhat from the Pokémon video game and anime canon: most Pokémon can speak human language and regular animals (like birds and fish) appear alongside Pokémon.
