Kirgon was one of four sibling who traveled to the Island of Mata Nui on a ship. The ship was hijacked by Skakdi, and Kirgon and his sister Dreenan were thrown overboard, and washed up on shore. They were discovered and taken in by a Toa of fire, who worked as a doctor. Kirgon got sick of listening to the Doctor named Virthee, and left out own his own. Afterward, he joined the Le-Koro Gukko Force, eventually becoming a Gukko trainer. He spent decades training his Gukko riding, and has mastered the art of flying.
