The green boy was in space when his ship was attacked by Baby. Goku, Trunks, Pan, and Giru found him unconscious in the Deserted Starship and brought him to their spaceship before his starship crashed on a star. They brought him to planet Pital. There, the boy woke up and Baby took control of him in an attempt to attack Pan while she was visiting the planet, but stopped when Goku and Trunks arrived. Baby finally left his body for that of a doctor from Pital.
