Having defeated the Red Ribbon Army single-handedly and taken their Dragon Balls, Goku finds that one is still missing! To locate it, he goes to the palace of the All-Seeing Crone, Baba Uranai, who can find anything in the world...for a price! The crone agrees to find the Dragon Ball for free if Goku and his friends--Yamcha, Pu'ar, Kuririn and Upa--can best her five supernatural champions in one-on-one combat. but even if they can beat Dracula, the Mummy, and the Devil, the final challenger just might give Goku the shock of his life!
There's only one dragonball remaining, but for some reason it doesn't show up on the radar. In a jam, Goku and co. go to Uranai Baba, who is said to be able to find anything that you're looking for.
In order to get her to divine for them, Goku and co. end up fighting Uranai Baba's five competitors. Goku survives to the last competitor, who gives him a tough battle. The identity of the amazingly powerful final competitor was Goku's grandpa Son Gohan.
