From Bulbapedia, the community-driven Pokémon encyclopedia.
Oluolu (Japanese: オルオル ʻOluʻolu) is a recurring character who first appeared in Pulling Out the Pokémon Base Pepper!. He is a famous Pokémon Base player from Melemele Island who plays for the Magikarp (Japanese: コイキング Koiking). He is also a graduate of the Pokémon School.
Professor Kukui saw Ash's excitement after watching one of Oluolu's Pokémon Base games on television. As a result, he and Principal Oak arranged a Pokémon Base match for the students of the Pokémon School and their Pokémon, with the three adults commentating the match. When Team Rocket arrived, with Jessie wanting Oluolu's autograph, he agreed to participate in a game between the students and the evil trio. Just when it seemed like Team Rocket was about to win, Oluolu had his Snorlax perform the Z-Move Pulverizing Pancake, allowing the school team to win the match. Despite Team Rocket losing, Oluolu still offered Jessie his autograph as thanks for the good game, but before she could take it, Bewear showed up and carried the trio away.
He appeared again in SM048.
Much like Samson Oak, Oluolu has a habit of making Pokémon gags, accompanied by a visual imitation of the Pokémon in question.
