A Gambler, Gamer, or 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 and III, they are depicted as old men with dice and a dice cup. In Generation IV, they are depicted as young men in trenchcoats with coins.

While they were known as Gamblers in Generation I, this was changed to Gamer in Pokémon FireRed and LeafGreen 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, 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, they use various Pokémon, but tend to rely on luck rather than skill. They mostly use one-hit knockout moves such as Horn Drill, along with moves that also knock out the user but not always the opponent, such as Explosion.
