Jiren is the last antagonist in Dragon Ball Super. I thought he was way too powerful and he didn’t have a very interesting backstory.
He basically serves as the juggernaut that everyone from every universe fears. He spends most of the tournament of power just meditating.
Nobody could seem to hurt him, no matter what powers they tried.
But at the very end, Android 17 Frieza and Goku manage to defeat him.
And he remains erased from existence for about 5 minutes until Android 17 wishes him back along with the other universes.
