Jiren from Universe 11 was one of the strongest characters in Dragon Ball Super but his strength became his greatest enemy as he went through life.
Akira Toriyama's Favorite Dragon Ball Character (It's Not Goku)
One of the strongest characters the Dragon Ball universe has ever seen is Jiren from Universe 11. Jiren was the number one fighter in Universe 11, and he was the one who gave Goku a run for his money. His power was next level, and no matter what Goku tried, he couldn't knock him out of the battlefield. This also earned him the title of one of the strongest mortals in the entire multiverse.
Jiren's belief in justice and honor led him to become even stronger than the God of Destruction in his universe. His strength came from his need to fulfill his responsibility as the most powerful member of the Pride Troopers and create a universe of peace and prosperity.
But he had great character development throughout the Tournament of Power, and many of his views on life changed. One of the most important realizations he had was that he overworked himself to become strong and maintain peace, which led to him becoming bored with the adventure of a decent battle.
