Some worthy mentions but Jack Johnson surely has to be up there,he was practically hated back when he was fighting and afterwards tbf but he took it all in his stride and gave just as much back and really knew how to play to the masses both good and bad,certainly a larger than life character which to me is what charisma really is all about .
Muhammad ali any other answer is a joke Ali literally transcended the sport and put it on a whole other level when it was looked down upon in the early 50s.
Having charisma doesn`t mean you`re attractive, Hitler made charismatic speeches asd did Winston Churchill, but I wasn`t attracted to either of them, lol
Gervonta Davis and Ryan Garcia. These two young men are drawing the most interest, both causal and serious fans.
Of course you weren't attractive to them. Odds are they died before you were born and if not they certainly didn't know you existed.
