Dragonball Z: Revenge of The Saiyans

Thousands of years before the events of Dragonball Z and Dragonball, early Saiyan warriors invaded Earth. Earth, wasn't advanced at this time and couldn't fight back. But one saiyan warrior named Progresso betrayed his people and helped the human's defeat the evil Saiyans. The the saiyans killed part of the human race which enraged Progresso causing him to transform super saiyan. As a super saiyan, Progresso fought the evil Saiyan ruler King Pepper (an ancestor of Vegeta's.) But to save the humans Progresso sacrificed himself which killed King Pepper along with him. At last the Saiyan's were defeated but the people of Earth mourned over the death of Progresso their hero. They worshipped Progresso over the centuries and told stories of how he had saved mankind. But then they had forsaken Progresso. Eventually it had been a time Earth forgot. They had not known it but deep in the Earth were the remains of the evil King Pepper which had been sealed away. On Earth in present day not too long after the events of the Cell games saga some scientists from the Capsule Corporation are in a dessert and they have uncovered ancient artifacts. Bulma and Krillin are with them examining the artifacts. Krillin calls Gohan and Gohan tells Chi Chi about it. Chi Chi lets him because she assumes it's educational. At the digsite Gohan notices strange ancient runes on one of the artifacts. Vegeta comes and examines it and says its ancient Saiyan writing. It is written "Here lies the remains of King Pepper." Bulma and Gohan have no idea who it is. But Vegeta tells them King Pepper was his ancestor but most saiyans thought him a legend. Vegeta digs up the grave and sees a dead skeleton laying there wearing saiyan battle armor resembling Raditz's armor. Vegeta read another ancient Saiyan rune but it actually turned out to be an evil chantation and King Pepper's skeleton comes to life and attacks them. Vegeta goes Super Saiyan and fights King Pepper. He used gallick gun which should've killed King Pepper if he were alive but instead blasted his armor off. None of Vegeta's attack's work on King Pepper because he's already dead. King Pepper knocks Vegeta unconscious. Gohan goes super saiyan and Krillin and Gohan fight King Pepper. King Pepper shoots a ki blast through Krillin's chest seemingly killing him. Gohan enraged by this continues fighting King Pepper. But not even he can defeat him. He then turns ascended super saiyan hoping he would be able to beat him like that. Gohan uses special beam cannon through King Pepper's ribs and it actually worked but King Pepper still lives and he kills the capsule corp scientists with a single blast of ki. Gohan becomes enraged and turns super saiyan 3. Goku and King Kai watch the battle from the otherworld and are amazed because Goku hadn't even turned super saiyan 3 yet. Even super saiyan 3 Gohan is no match for him. King Pepper begin's draining Gohan's energy weakening him. He faints and reverts back into normal Gohan. King Pepper uses Gohan's super saiyan energy and transforms. He is not a skeleton anymore standing in his place was a normal looking Saiyan warrior in battle armor and in super saiyan form. Now King Pepper may be stronger than before.
