Tapu Bulu (Ruins of Abundance)

Details: After defeating the Elite Four and finishing the main storyline, the player can go to the Ruins of Abundance at anytime and Battle the Ula'ula Island Guardian Tapu Bulu by interacting with the pedestal.

Tapu Bulu will be at Level 60, knowing the Moves of Nature's Madness, Zen Headbutt, Megahorn and Skull Bash. It is a Grass/Fairy Type Pokemon. It has the ability of Grassy Surge, which creates an Grassy Terrain within the Battle. With this type of terrain, the powers of Grass Moves increase by 50%. Pokemon on the ground will also gain 1/16th of their HP every single turn.

Since Tapu Bulu is a stationary Legendary Pokemon, it can be battled again if a player were to run or accidentally defeat it. However, the player will have to defeat the Elite Four again before Tapu Bulu reappears.
