rjj is a fusion himself I would go with Julian Jackson 1 punch power with mayweathers defense and accuracy Would destroy anyone
If you fused Hearns and Margarito, Tommy would downgrade significantly. He would become much slower, his jab would be less sharp, and his ring I.Q. would diminish. You ****ers need to study dragonball z to understand how fusion even works. :fire
Berto/Mayweather, would be Mayweather with a proper shoulder roll but Berto's raw power Wilder/Muhammad Ali Ali's jab, Wilder's one punch knockout power
George Foreman (1973) with Rocky Marcianos stamina Nobody could survive Foremans strength and power along with being able to throw hard punches constantly for 12-15 rounds...
