Legendary Super Saiyan Uub
14 years ago Majin Buu was defeated. The Z-fighters experienced peaceful times. Son Gohan worked as a professor in a College, Son Goku trained with King Kai to increase his power further and Vegeta trained with the Gravity Machine but his improvement slowing down. Piccolo trained and mentored Dende as being Guardian of Earth. Kirilin worked as a Police Officer and Android 18 was a Housewife just like ChiChi. Videl was a Math Teacher in a Highschool.
Somewhere south a 13-year-old boy with the name Uub packed his belongings for travel to the West City where his life would change drastically, little did he know he was an anomaly because he was reincarnated from two beings Majin Buu and Legendary Super Saiyan Broly. Because of this, he was born with power-level of 50.000 but his power would grow constantly his power-level was already 5.000.000 and he has never trained in his life.
Somewhere at the edge of the universe a being woke up a being known as God of Destruction Beerus. He dreamed about Super Saiyan God and a Human with powers of Majin and Saiyan. Made his way to earth to fight Super Saiyan God and find the Human.
