Video game appearances
In Dragon Ball: Advanced Adventure, the Crystal Ball is trophy No. 51. In Dragon Ball Z: Buu's Fury, Old Kai's Crystal Ball can be seen on the planet of the Kais and Baba's Crystal Ball is the Z-Fighter Exhibit #8.

On the second planet, he meets a fairy stuck inside a Crystal Ball. He breaks it and frees the fairy by transforming into a Super Saiyan.
In Dragon Ball Z: Attack of the Saiyans, before they leave Kame House to train for the 23rd World Martial Arts Tournament, Master Roshi asks Krillin, Yamcha, and Tien Shinhan to go in a cave on Training Island and retrieve the Crystal Ball his sister gave him. There, Roshi confronts the boys disguised as Jackie Chun to test them. Once they bring back the Crystal Ball, Roshi gives it to them as a reward for completing their training at Kame House. The Crystal Ball is then used in the menu to display the Z Fighters' objectives, the enemy list, and the Z Fighters' team attacks. Also in Attack of the Saiyans, Kami's Crystal Ball is a capsule item named Kami's Eyes that prevent enemies from sneak-attacking the Z Fighters.
Babidi uses his Crystal Ball to strike his opponents in Dragon Ball Z: Budokai Tenkaichi 3 and Dragon Ball: Zenkai Battle Royale. In Dragon Ball Z: Battle of Z, Babidi's Crystal Ball is an item that renders its user invincible for thirty seconds from battle starts.
- Throughout the franchise, there is a large inconsistency in the strength of Baba's Crystal Ball: her ball explodes because it is overwhelmed by the incredible powers of Goku and Vegeta during the Vegeta Saga, it has no such problem in the Cell Games Saga, despite most (if not all) of the Z Fighters, as well as Cell, being many times stronger than they were in the Vegeta Saga. This could be explained by the fact that her Crystal Ball is made more durable in the Cell Saga.
