Why Raditz is THE KEY to Dragon Ball Z.

The Brother of Goku / Kakarot is more important than you think. In fact, he is probably the most PIVOTAL and KEY Villain to Dragon Ball Z. Yes, more than Frieza. Raditz is the overshadowed son of Bardock and Gine. The underappreciated Uncle to Gohan and the betrayed ally to Vegeta. But more imporantly, he was a successful bridge from the Original Dragon Ball to the Story of DBZ.
