Despite being one of the most powerful and mysterious enemies that the Z-Fighters had ever faced in the history of Dragon Ball, we haven't seen much of Jiren within the canon story of the franchise. Dragon Ball Super's Tournament of Power introduced this character as the ultimate powerhouse for whom Goku had to unlock a divine technique to defeat and was considered to be a one-man army for Universe 11. However, despite his overwhelming power, Jiren was defeated by Universe 7 and hasn't been seen since the end of the tournament.
