Gladion sent Porygon to battle against Hau's Pichu. Porygon fired Psybeam against Pichu's Charge Beam, causing a collision. Hearing Hau entered the tournament for fun, Gladion had Porygon intensify its attacks, which defeated Pichu. Moon, who had her Grimer battle Gladion's Porygon, wondered why didn't Gladion attack at close range, like he did in the battle against Hau and Pichu.
Hau came to Exeggutor Island to speak with Hala. He showed he was training hard for the last six months, as he showed his Pikachu and Brionne, who had evolved.
