An unnamed alien boy (謎の少年 Nazo no Shōnen, lit. "Mysterious boy") whose body was possessed by Baby.
Dragon Ball GT
Main article: Baby Saga
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.
Shadow Dragon Saga
- It is unclear if Baby implanted the green boy with a Tuffle Parasite or not (if Baby did presumably Kibito Kai brought some of the Sacred Water to Pital via Kai Kai to free him of the Tuffle Parasite's control).
