10 Postgame Challenges In Pokémon Sun And Moon
8. Catch All Of The Guardian Deities
The Guardian Deities are next up for the Ultra Ball treatment. You will have already battled - and hopefully caught - the Electric/Fairy Tapu Koko after completing the main story; now it’s the turn of the other island guardians.
You can find the Psychic/Fairy Tapu Lele in Akala Island’s Ruins of Life, the Grass/Fairy Tapu Bulu in Ula’ula Island’s Ruins of Abundance, and the Water/Fairy Tapu Fini in Poni Island’s Ruins of Hope.
You’ll have to beat a simple puzzle at each location before you can challenge the Tapu. At level 60, they’re all pretty strong. As long as you’re battling with the team you used to beat the Elite Four, you shouldn’t have too much trouble.
