Dragon Ball Z marked a major shift for the franchise, expanding the story far beyond what Dragon Ball had set up. Because of this, many fans consider it the best anime from the franchise.

As you may recall, the series begins with the introduction of Raditz, who arrived on Earth to recruit his younger brother "Kakarot." But, do you remember why Raditz wanted Goku to join the Saiyans?
