FanofRPG's DBZ fanfiction

I have no real name for it honestly. But here it goes. Here is the origin for the villain first

Age 864

A being came to the world with remarkable power, his name was Cygnus. He was absolutely destructive and decided to escape the galaxy at the age of only 11. The first planet he decided to train on was in what was left of the South Galaxy (Courtesy of Brolly and Frieza). The planet was -200 degrees and had x5 gravity but he got used to it in just a week. He trained hard and in just 1 year he was able to lift 50,000 tons and train under 50x gravity. Suddenly a ship landed with the grand monarch Boreas and his cousin, Kelvos. Both are direct decendants of Frieza and Cooler. They discovered Cygnus and fought against him, Cygnus was a slightly stronger than Boreas and quite a bit stronger than Kelvos and won. Kelvos nicknamed him "Super Slash" due to a lot of large slashes and cuts he got from Super Slash. He became the prince and soon the king.
