This colosseum becomes available to the player after they clear Sunny Park Colosseum. In this colosseum, the player must defeat three Trainers, followed by the Colosseum Leader, in Select Battles. In a Select Battle, a random selection of twelve Pokémon is provided, and both Trainers must select their team from the random selection. It is possible for both Trainers to choose the same Pokémon.
The first time the player challenges this colosseum, they will have to face Double Battles, using the Level 30 Open ruleset, on Rank 3. All Pokémon in this ruleset are level 30. After the colosseum has been completed for the first time, the player can fight through ranks 4-8 in Single or Double Battles. Regardless of which battle type is chosen, winning on the selected rank will advance the rank by 1. After clearing all eight ranks, any subsequent challenges to this colosseum will always be Rank 8.
After the player completes Stargazer Colosseum the first time, the Level 50 All ruleset is unlocked for this colosseum. The player's starting rank on Level 50 All is set to 1, and is maintained separately from their rank in Level 30 Open. The rank can be advanced by Single or Double Battles. Pokémon in this ruleset are level 50.
In Single Battles, the player and opposing Trainers all have six Pokémon, and must choose three to participate in the battle with. In Doubles, all Trainers have six Pokémon, and must choose four.
The Pokémon that can be used by opposing Trainers differ depending on the level mode being played, and whether the player is playing Singles or Doubles. The links below will show the Pokémon pools used by each.
Completing this colosseum for the first time unlocks Courtyard Colosseum.
When fighting on Rank 3, there are always six Pokémon that are always the same species and have the same moves and item, but can have different IVs and Nature. The other six will be random, but due to how they are selected, they tend to be weighted towards a certain part of the possible encounter selections. More details are given under each Trainer.
The six other Pokémon in the pool when fighting Pikachu Fan Stewart are largely going to be selected from the Pokémon at the beginning of the Rank 2 pool. While it is possible for any Rank 2-4 Pokémon to be chosen, the likelihood of each Pokémon gets much lower the further down the list it is.
