You are a smarter, more prepared version of Zamasu. In this alternate reality, you and Goku Black attacked after the tournament of power. You have trained hard after meeting Black and have prepared to execute the zero mortal plan and have used the Time Rings to find out where the Super Dragon Balls were and used them again to give you a very dangerous power rather than make you immortal. You and Black have finally obtained true power, sadly for you, Vegito decided to call in some help. Although she seems to have a facination with you, and think your sexy, that could be good or bad in your case. Same with the others.

No one dared to challenge the most powerful being this world has ever seen.

After YN was defeated by the Son family he was transported to a different planet where he would live out the rest of his years training and thinking about what could have happened if he wasn't a slave to his father. However he gets an unexpected visitor who needs him for a certain tournament.
