Zaiko is the son of Kyuri and Selari and he is considered the Strongest Saiyan Alive until his death, which soon passed on to Goku and Vegeta. He is a Kyurian by law, and a pure Saiyan Elite by history like Kyuri unlike his mother. After his death as a child and Kronos being defeated, he was revived back by Kronos himself to take care (in a bad way) of the Z Fighters. He was recognized throughout his planet as a kind hearted prince but later on he returns as a negative and dark minded adult.
