Kourne

Kourne was chief of the Saiyans Planet Plant (which later became Planet Vegeta), the father of King Vegeta, and grandfather of Vegeta. He was assassinated by Tuffle terrorists in Age 720, this being one of the many reasons that motivated Vegeta to fight against the Tuffles in the Saiyan Tuffle War, the other reasons being that they were tired of sharing the planet with them, there was civil unrest, and they wanted the Tuffles technology and wealth. Kourne's name is a pun on corn.

Appearance and personality
Kourne was a large, hardy man, the same size as Ox-King, with long grey hair and a huge beard, who wore the same type of fur clothing that all Saiyans wore before the Planet Trade Organization (like the kind you see in the flashbacks where King Kai tells Goku about Saiyans).

Kourne was a jolly man who loved to eat a lot, and was also known to be arrogant, and loved to fight. He had a lot of pride, much like his son and grandson.

Power
Kourne was almost as strong as King Vegeta was in 737, and was feared by both Saiyans (those who opposed him) and Tuffles. The Tuffles were especially afraid of him, and so, assassinated him with a powerful energy weapon, when he was off guard.
