D.B.Z: Saberionians Attack Earth.
Prologue
Narrator: Fifty years ago, the planet called Cyberionia was attacked by Frieza and his henchmen. Cyberionia was home to a human-like race called the Saberionians.
The Saberionians easily defeated Frieza and his henchmen therefore a truce was called and an alliance was created between the Saberionians and the Cold Army. The Saberionians soon after joined forces with Frieza in his conquest over the galaxies.
After many years of ruling the universe, Frieza was defeated by Goku (in his Super Saiyan form). By this time the Saberionians held a higher position than Frieza and his father, King Cold, within the army.
After his defeat, Frieza was later rebuilt by his father King Cold. Prince Frieza then asked his father if he can go to Earth for revenge and his request was granted. They went to planet Earth to destroy the Super Saiyan named Goku.
When Frieza with his father arrived on planet Earth, Goku was not there. Instead there was someone else waiting for them, a man with a sword named Trunks who later turned out to be a Super Saiyan also. He then killed King Cold and Prince Frieza effortlessly, but the Saberionians were angered by this move the Saiyans had made. The Saiyans had killed their allies. The Saberionians wanted a lot of revenge, after much planning and training they headed to Earth. By the time the androids attacked, the Saberonians were nearing planet Earth to destroy it in the name of King Cold and Frieza.
