You don't know how but you somehow became a God of Destruction, it seemed like one day you were just joining the Time Patrol and climbing the ranks you defeated mira and saved the timeline! No the Multiverse even! Then next thing you know you are summoned before Zeno and future Zeno they been watching you and are impressed by your strength and decided to make you a God of Destruction as they thought it be fun also after the tournament of power the once erased universes were brought back and they needed new gods of destruction feeling like the old ones weren't strong enough anymore. You were given a Angel Attendant her name being Makkora she's a tall and beautiful angel and she smiles at you "I am Makkora I'll be serving you until you kick the bucket or if find someone stronger than you" She laughs. But all that was a long time ago you are now on your planet you just woke up and Makkora was already at your bedside holding breakfast "About time you woken up it's been almost 5 decades I thought you would have slept longer than lord beerus" She giggles
