Wyndon Stadium (Japanese: シュートスタジアムShoot Stadium) is the official Stadium of Wyndon. The largest stadium in Galar, Wyndon Stadium serves as the venue for the Galar League's Champion Cup.
Rather than facing an Elite Four like in other regions, the Champion Cup is a single-elimination tournament that determines who is eligible to challenge the Champion for the title.
The Finals is a single-elimination tournament of the eight finalists: the player and all the Gym Leaders, minus Opal. All Trainers battled during the Finals will Gigantamax their last Pokémon at the first opportunity.
Bede
Before the Finals officially commence, Bede will suddenly enter the stadium and challenge the player.
Before the Champion Match between the player and Leon begins, Chairman Rose will suddenly interrupt the tournament via a broadcast, announcing that he has brought about the Darkest Day. The battle against Leon will recommence after the player has defeated Eternatus.
After completing The Crown Tundra story, the player is allowed to compete in the Galarian Star Tournament at Wyndon Stadium, which consists of a Multi Battle elimination tournament with NPCs that the player has already met.
In the next episode, Ash and Goh tried to battle the Drednaw, but their attacks were ineffective against it. However, after Pikachu unexpectedly Gigantamaxed and Leon gave Ash advice, Drednaw was defeated and returned to its normal size. The next day, Leon invited Ash to a battle at the stadium, like he had requested earlier. The clash between Ash's Gigantamax Pikachu and Leon's Gigantamax Charizard ended in Leon's victory. Afterwards, Leon promised Ash that they'd have an official rematch one day.
Wyndon Stadium appeared in Letter, where a battle between Bea and Leon was broadcast. After the battle ended in Leon's victory, Chairman Rose and Oleana took a Flying Taxi found outside the stadium and used it to travel from to a children's hospital.
The stadium briefly reappeared in Early-Evening Waves, where Nessa was confronted by Chairman Rose in the locker room after losing a match against Milo.
The stadium was briefly seen again in Assistant, where Chairman Rose and Oleana flew over it in a Flying Taxi while a battle between Gordie and Melony was taking place there.
Trivia
Wyndon Stadium appears to be based on Wembley Stadium, the stadium of the England national football team. Wyndon Stadium's design incorporates the Wembley Arch, a landmark of the stadium.
