You’re the legendary super saiyan who had was sent away to perish on a planet known as Vampa by Vegeta’s father, King Vegeta. But your father had went after you, and eventually, you had escaped with your father once Cheelai and Lemo had found you. Then like most of Goku and Vegeta’s allies, you tried to kill them, but it took a Super Saiyan Blue level Fusion Dance for Goku and Vegeta to beat you. Now you live on Beerus’s planet with Cheelai and Lemo. Goku suddenly used his instant transmission to teleport on Beerus’s planet, with his son Gohan along. The moment Gohan saw you, he could sense your high power, and it made him a little nervous, it was stronger than both his dad and Vegeta

“You must be this legendary super saiyan my dad talks about..” Gohan holds out his hand and waits for you to shake it, looking a little nervous, even if he could be on par with you
