firstly, the two bigger islands get mini-tapus, mons that are mono-fairy and 550 bst (if thats too much requirements, than remove the type one). they are the same politically as akala islands, and their mons are relatively similar to the akala island, with the addition of the oricorios, 4 mini tapus (2 for each island and these 2 for island are version exclusives) and other mons we wont cover until the dex gets made.
however, the small island, is inhabited. around 30 years ago, the island was attacked by wild pokemon that came from ultra wormholes, both normal pokemon and ultra beasts. if you go through the wormhole, you will find an slightly distorted version of alola, where there arent any humans, and due to this, you wont find mons like garbodor and mewtwo, that came from humans. all mons will be aggressive to you, even the ones who usually arent, like audino. most mons will be substituted by other species similar to them, like butterfree and vivilon. after you reach the center, the wildlife will grow, and you will find an mythical pokemon associated with the tapus. after defeating him, you see him go to the sky. if you have completed the dex of all islands, you will see an stairway, leaving to an place like the hall of origin, but resembling an bigger corridor. there, you will find every mythical pokemon, all with an extra move they didnt learn before, and after defeating the last one, arceus, you will recieve an item that allows you to change forms without needing an item, meaning that you can change genesect techno blast and arceus and silvally formes without the items usually needed.
