The Grand Festival is the final challenge for all Pokémon Coordinators. Kanto, Johto, Hoenn, and Sinnoh each hold the tournament once a year and is the Pokémon Contests' analog to the Elite Four Challenge.
The general structure of each Grand Festival is similar: Pokémon Trainers/ Coordinators must win at least five Contest Ribbons of a specific region in order to be able to participate in that region's Grand Festival. The winner receives the Ribbon Cup, as well as the title of Top Coordinator.
Due to the large number of participants, Grand Festivals has more judges in attendance.
The Hoenn Grand Festival is held in Slateport City, while the Kanto Grand Festival is held at Indigo Plateau. The Sinnoh Grand Festival is held at Lake Valor. There is also a Johto Grand Festival is held at Olivevine City.
The tournament is divided into two parts: the appeals portion and the battle portion. Grand Festivals follow the same guidelines as Contests except where noted below.
Coordinators show off their Pokémon's moves in order to impress the judges and the audience. The appeals are awarded points by the competition jury, and the Coordinators with the highest scores proceed to the next round.
- In the appeals stage of Kanto and Hoenn Grand Festivals, there are two rounds to appeal. In the first, Coordinators have their Pokémon performing with no more than one move, while in the second, Coordinators have their Pokémon using as many moves as necessary.
- The Sinnoh and Johto Grand Festivals only have one appeals round instead of two. The competition is held under the Double Performance rule, which means that Coordinators must use two Pokémon in all rounds.
- In all Grand Festivals, only the best 32 Coordinators proceed to the battle portion.
In the battle portion, Coordinators shows how skilled they and their Pokémon are when put into battle. Competing Coordinators are matched-up randomly.
- All battles follow the Double Battle style.
- Whoever loses is out of the tournament.
- The Coordinator who wins the fifth and final round of this portion is then declared the winner of the entire competition.
