After becoming the Champion, the player may repeatedly participate in a Champion tournament at Wyndon Stadium, which consist of three rounds in a single-elimination tournament.
Special Trainers
These Trainers may appear in the tournament after receiving their rare League Cards, either randomly or by the player's invitation. With the exception of Piers, they all have a Pokémon that they will Gigantamax at the first opportunity. They are listed in the order they are presented when asked for an invite by the League staff attendant. If the player chooses to invite one of the following Trainers, that Trainer is guaranteed to appear somewhere in the tournament bracket, but may not necessarily be battled if eliminated early.
The following Gym Challengers may also appear during a Champion tournament. Their Pokémon are typically at a lower level than the above Trainers', and these Trainers do not use Dynamax.
