Despite the character’s obvious limitations, such as his advanced age and inability to fly, Master Roshi is the strongest of Earth’s humans.

First, in the Tournament of Power, an event that tested the skills of warriors at an unprecedented level, Master Roshi performed exceptionally well. What really stands out is the comments from the two gods Whis and Beerus about Roshi’s abilities. He has nearly mastered an as-yet-unrevealed technique similar to Ultra Instinct.

Master Roshi possesses skills almost on par with the gods of Dragon Ball Super

Even without complete knowledge of the technique, Roshi displays an intuitive understanding that even a God of Destruction like Beerus has not been able to perfect. This is due to the wisdom and accumulated experience that Roshi has acquired over the years, making his age an advantage rather than a disadvantage.

Second, in the fight against the escaped prisoners from the Galactic Prison, all human warriors except Roshi encounter insurmountable obstacles.

For example, Tenshinhan and Krillin faced setbacks, while Roshi remained a pillar of strength and resilience. He even advised Krillin about the futility of his efforts, hinting at the Roshi’s superior level of perception and skill.

Furthermore, Roshi’s only “weakness”, the fact that he has difficulty facing female opponents due to his impure thoughts, is ultimately another testament to the old turtle’s strength. He overcame this weakness barrier by fighting blindfolded. He forced his opponents to unite, which was an impressive feat.

In short, both Master Roshi’s intelligence and abilities in Dragon Ball Super firmly establish that he is the strongest earthling in the Dragon Ball universe.
