Sonic GX Ch. 0 - Prolougue
A long time ago, there was a being known as Retsu Taimukipa. With her powers beginning to drain, she used the last of her energy to create a mystical device, known as the Aelitatrix. She fired it to another section of the multiverse, hoping one day it will be discovered by the chosen wielder.
She then fell into a deep sleep until the day when the Dimensional Protection Unit will be needed once again. 200 years later, it was discovered on Planet Vegeta, by a Saiyan known as Bardock. At that time, his wife, Fasha, had given birth to two sons, Kakarot and Arufunu. He bestowed it to his youngest son, hoping he would be able to use it one day.
