Yuki Tengoku is a fictional character who does not appear in the official Dragon Ball series. With a name meaning 'snow heaven' in Japanese, Yuki Tengoku could be imagined as a mysterious fighter possessing ice-based powers, perhaps introduced as a new rival or ally to the Z Fighters. In this imagined role, Yuki would bring a cool demeanor and unique abilities, challenging Goku and his friends while seeking their help to battle a greater threat, ultimately becoming an integral part of the team.
