King Orion

King Orion was the father of King Vegeta and grandfather of Vegeta. He was assassinated by Frieza after the mutant war. He had visions of his death as well as a Saiyan Warrior becoming Super Saiyan and defeating Frieza. When Frieza alongside Dodoria, Zarbon, and the Ginyu Force attacked he told Frieza of his vision. Frieza merely laughed and said that no mere myth in Saiyan Mythology would save them and shot a death beam through his chest killing him. Hey looked like a Super saiyan because he had blond hair.
