Frieza
During the TV Special, Frieza mulls over the Saiyans' increasing power until Zarbon advises his master to eliminate Bardock and his team. In the end, Frieza is challenged by Bardock himself, who survived the onslaught and wants revenge for the death of his crew. Bardock fires a ki attack at Frieza, who makes a huge energy ball and cancels out Bardock's attack. Frieza then sends the ball straight into the core of the Planet Vegeta, wiping out almost the entire Saiyan race and many of his own henchmen.
