A PI (Japanese: ギャンブラー Gambler), previously known as Gambler and Gamer, 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. 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.



This Trainer class was originally known as Gambler 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 Pokémon 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, Platinum, Brilliant Diamond, and Shining Pearl, the Trainer class is instead named PI (private investigator), likely because of the trenchcoat's stereotypical association with detectives, but all their dialogue still revolves around gambling.

Other languages

In Japanese, this Trainer class has consistently been named ギャンブラー (Gambler) in all games in which it is present.

In other languages, while the Trainer class name is often censored to a term similar to "Gamer" in later generations, no other language names the Trainer class "PI" like the English version.
