Note: This story includes Xicor, a character from Toyble's DBAF but MUCH different. He is the product of the West Supreme Kai and Goku's DNA, who is MUCH more powerful than anyone else and then needing to be sealed for a while for the gang to train to try and beat him when he escapes.
After the events of the Moro Arc, Goku and Vegeta go to train with Whis as to train up Ultra Instinct and Vegeta to try and learn the Hakai. Everything is going normal and Earth is safe. However, in a lab on Earth, a single project laid in a pod.
He had white hair, but had two massive black pieces of hair as well as two small black spikes on the bottom of his chin. The project sported grey eyes; his hair was stood up and the bottom of his hair simply spiked downwards. This creation would awaken, a Saiyan being born once more, but his Ki was malevolent.
The funny thing was, it had a sense of...good. Gohan and Piccolo would go to check it out, finding a man wearing a green Gi similar to his own and his fathers except green. The two must challenge him and wait for Goku and Vegeta to arrive, as he seems to be surpassing them quite quickly!
