A PI (Japanese: ギャンブラー Gambler) is a type of Pokémon Trainer that first debuted in the Generation I games. In Generations I, III, and VII, they are depicted as old men with dice and a dice cup. In Generations IV and VIII, they are depicted as young men in trenchcoats flipping coins.

While they were known as Gamblers in Generation I, this was changed to Gamer in Pokémon FireRed, LeafGreen, Let's Go, Pikachu!, and Let's Go, Eevee! to avoid gambling references. As a result, some jokes were lost, such as in FireRed and LeafGreen when Gamer Rich describes himself as a "rambling, gaming dude" instead of a "rambling, gambling dude." In the English releases of Pokémon Diamond, Pearl, and Platinum and Pokémon Brilliant Diamond and Shining Pearl, the Trainer class name was changed once again to PI (private investigator), likely because of the trenchcoat's stereotypical association with detectives allowing for hiding the censorship, but all their dialogue still revolves around gambling. PIs can also appear in Johto's Battle Frontier.

In all games since Generation IV, they exclusively use various Pokémon that tend to rely on luck over skill, specializing in one-hit knockout moves such as Horn Drill. In the Battle Tower and Battle Frontier, all their Pokémon know either a one-hit knockout move or a move that involves the user fainting, such as Destiny Bond or Explosion. In Let's Go, Pikachu! and Let's Go, Eevee!, their Pokémon are several levels higher than other comparable Trainers' in the routes they're in to further increase the odds of their one-hit knockout moves connecting.

In Let's Go, Pikachu! and Let's Go, Eevee!, Gamers will award three Poké Balls along with prize money upon being defeated.
