>>29772677So going by the level of their pokémon and their teams, I think it goes like this:
Melemele
>Ilima's trial - Normal>Hala's grand trial - FightingAnd then you become able to fight Ilima
Akala
>Mallow's trial - Grass>Kiawe's trial - Fire>Lana's trial - Water>Olivia's grand trial - RockAnd then you can battle the other three captains
Ula'ula
>Sophocles' trial - Electric>Acerola's trial - Ghost>Mina's trial>Nanu's grand trial - DarkBut you can't rematch the captains yet because of the Aether/Skull shit going on
Poni
There's probably some legendary thing going on here as well. Once it's done you can battle the Kahuna
>Hapu's grand trial - GroundThen you finish the first part of the main game and can challenge the pokémon league
League
>Hala - Fighting>Olivia - Rock>Acerola - Ghost>Kahili - Flying>Kukui - ChampionThen you finish the main game and can have a rematch against Sophocles, Mina, Nanu and Hapu. And you can also rematch the E4 later.
Sounds like a clusterfuck.
