Elio is the male main protagonist of Pokemon Sun, Moon, UltraSun, and UltraMoon. He's an 11 year old boy who moved to Alola from the Kanto region. In the games, he chooses a starter, participates in the Island Challenge, defeats the Aether Foundation and Team Skull, as well as Necrozma, and becomes Alola's very first Champion.
He makes his anime debut in the music video "GOTCHA". Ash Ketchum's outfit in Alola was based off Elio's Sun and Moon outfit.
