Official artwork and details for Poni Island guardian deity Tapu Fini in Pokemon Sun and Moon

The Water/Fairy type Tapu Fini is the guardian deity of Poni Island. This Pokémon is able to attack by manipulating water. It does not like to risk being harmed during battle, so it creates a thick fog to disorient its opponents and lead them to their own destruction. Tapu Fini has the Ability Misty Surge, an Ability that no other Pokémon has previously had. With Misty Surge, the field will be turned into Misty Terrain, halving the damage taken by Pokémon on the ground from Dragon-type moves and preventing them from being afflicted with status conditions or confusion.
