Suggested by Anonymous Zamasu is one of the strongest Dragon Ball Super villains out there. He can end the solar system in a single shot with ease. He has FTL combat speed and that means game over for Master Roshi. Roshi is entering the tourney along with Goku and the others, but I’m not buying it. Far as I’m concerned he is never going to be on Zamasu’s level. He is only human after all and has limitations. Zamasu wins.
