Once they rescue him and take him elsewhere, the man introduces himself as Hoi and presents them with a music box, inside which he claims a hero named Tapion is trapped, and may be the Earth's last chance against an approaching evil. When even Goku fails to open the music box, the Z-Fighters gather the Dragon Balls and ask Shenron to open it for them. Tapion is released, but expresses anger at Hoi and Goku for freeing him, explaining that inside him is the essence of half of the ferocious monster, Hirudegarn, before fleeing into isolation.
