Brad Jackson

Bradford Jackson voiced several key Dragon Ball characters across multiple series. He provided the English voice for Oolong, the pig-shaped shape-shifter who appears throughout Dragon Ball and Dragon Ball Z. Jackson also voiced King Cold, Frieza's father and one of the most powerful villains in the franchise, along with Haze Shenron in Dragon Ball GT. He voiced additional characters like Bon Para and filler characters Yordon and Atla.
