- 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.
