Official artwork and details for Ula’ula Island guardian deity Tapu Bulu in Pokemon Sun and Moon

The Grass/Fairy type Tapu Bulu is the guardian deity of Ula’ula Island. This Pokémon has the power to manipulate vegetation and cause it to grow. It can use this power to make its wooden horns change shape and grow larger. Tapu Bulu has the Ability Grassy Surge, an Ability that no other Pokémon has previously had. With Grassy Surge, the field will be turned into Grassy Terrain, boosting the power of any Grass-type moves used by Pokémon on the ground and restoring a bit of HP to them each turn. It also halves the damage taken from the moves Earthquake, Magnitude and Bulldoze.
