The Ultimate Saiyan
Prologue: Awakening
He came to consciousness in a tank, everything was blurry and strange he didn't know where he was or who he was, "activate his genetic memories" a voice floated in.
All of a sudden a massive rush of information came in. He was the Ultimate Saiyan, created from the DNA of the Saiyans Goku, Vegeta, Broly, Nappa, Raditz, Paragus, Tarbles, Trunks, Gohan, and Goten, and all of their knowledge and moves filled his mind."Keep project Ultan stable", another voice said. Ultan! His name would be Ultan!
Then another voice," Activate the machine."
Then he heard a whirring and finally looked out the tank to see people in white-coats scurrying around a strange machine that began to glow.
It sucked energy from somewhere very far away his Saiyan energy skills told him, and the energy began to fill him.
It was massive! Overwhelming!
His acquired knowledge told him this power would soon be around the level of an SS5.
Then a strange voice floated into his head, You will destroy Goku and Vegeta it said. Knowledge of their strength filled him and he was eager to fight them.
Wait you are too young it said.
And so he waited for three long years as his body matured 10 years every year and more things were taught to him.
