PKMN SV2/Grand Champion Invitational Trainers

The Grand Champion Invitational is a battle facility that the player is able to challenge after beating the main stories of Pokémon Scarlet and Violet 2. Like the Pokémon World Tournament in Pokémon Black and White Versions 2, The Grand Champion Invitational allows the player to challenge prominent non-playable characters that appeared in previous games.
All trainers that can appear in The Grand Champion Invitational are capable of using eighteen different Pokémon, of which six will be randomly chosen to be in their party. All of the Pokémon that can be used are capable of undergoing Terastallization during battle, with many of the Pokémon possessing abnormal Tera Types. Unlike the non-playable characters that appear elsewhere in the game, the trainers that participate in The Grand Champion Invitational will not exclusively Terastallize their final Pokémon, with the game instead randomly determining which one they will Terastallize alongside their party.
There are thirteen different tournaments that are part of the overall "Grand Champion Invitational" event. All possible participants can appear in the titular Grand Champion Invitational tournament, of which 32 will during any one attempt to challenge it. All other tournaments, which instead limit the amount of participants to 16, have a smaller selection of possible opponents that fit a specific theming.
The different tournaments that are part of the Grand Champion Invitational event are as follows:
