Frieza hates Saiyans primarily because he fears the legend of the Super Saiyan and views them as a potential threat to his galactic dominance.
The Fear of the Super Saiyan
Frieza's animosity towards the Saiyans stems from his deep-seated paranoia about losing his power and control. He learned of the legend of the Super Saiyan, a warrior with immense power capable of surpassing even him. The possibility of a Saiyan reaching this legendary form terrified him, making him see the entire race as a ticking time bomb. He also heard rumors of the Super Saiyan God.
Eliminating a Potential Threat
Driven by fear and a desire to maintain his undisputed reign, Frieza decided to eradicate the Saiyan race. He viewed this as a preemptive strike, eliminating a potential source of rebellion and ensuring his continued dominance over the universe. His plan involved tricking the Saiyans to return to Planet Vegeta and then destroying the entire planet with a single, devastating attack.
Frieza's Plot Unfolds
Frieza ordered all Saiyans to return to Planet Vegeta under the pretense of a mission. Unbeknownst to the Saiyans, this was a trap. As they gathered on their homeworld, Frieza unleashed a massive energy blast that obliterated Planet Vegeta and nearly all of its Saiyan inhabitants. This act cemented Frieza's hatred and fear of the Saiyans, resulting in his actions.
