Hala

ハラ

Hala is Hau's grandfather and the kahuna of Melemele Island. He specializes in Fighting-type Pokémon and awards the Melemele stamp to Trainers who defeat him. In Sun and Moon, he also joins the Alola Elite Four.
As revealed in League Offenders and Defenders! (SM128), Hala was formerly the mentor of Professor Kukui and Guzma. He tried to maintain peace between the two, but Guzma grew disillusioned with Hala's teachings and chose to grow strong on his own, without using a Z-Ring or Z-Crystals.
