P1 Grand Prix

The Pokémon Number One Grand Prix, known better as the P1 Grand Prix, is a special Pokémon battle tournament run by Silph Co. held especially for  in Celadon City. Each Pokémon Trainer who enters only one Pokémon and engages in a series of one-on-one battles. The prize is a golden championship belt. It was featured in The Punchy Pokémon and referenced in A Tyrogue Full of Trouble. Ash's Primeape and Brock's Geodude both entered into the P1 Grand Prix. However, Geodude was knocked out by 's, which was under Jessie's ownership at the time. Primeape won the tournament and belt after defeating several competitors over four rounds including this same Hitmonlee.

The P1 Grand Prix's definition of "Fighting-type Pokémon" for the tournament seems to be based on one from the Pokémon Trading Card Game rather than the Pokémon games or Pokémon anime, as Ground- and Pokémon can apparently be entered as well. In the TCG, Fighting, Ground, and Rock are all considered a TCG Fighting (single type). The TCG Fighting symbol appears on the poster advertising the tournament in the Fighting Spirit Gym.
