From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Hoi (ホイ, Hoi) is the last surviving member of the Kashvar.
Hoi appeared in Dragon Ball Z: Wrath of the Dragon. He searched long and far for the enchanted Music Boxes that contained and Minotia and Tapion. Hoi tried to jump out of a building knowing that Son Gohan and Son Videl (as the Great Saiyamen) would come to his rescue. He proceeded to tell them about Tapion and then tricked the Z Warriors into helping him locate the Dragon Balls. After he released Tapion, he finally found the missing piece to Hirudegarn and tried to use him to extinguish Planet Earth. Unfortunately for him, he was killed by Hirudegarn when the monster inadvertently crushed him under his foot.
