10Julia “The Jewel” Budd
The 5-foot-8, 145-pound Budd is a strike artist who is often able to use her reach advantage to pound her opponents into submission inside the time limit.
In her first 12 professional wins, exactly half came by decision, with the other half coming from the aggressive Budd violently attacking her foes. Five of those wins came via KO, with her preferred method of stopping a fight being her punches and elbows on a mounted opponent. You can’t get much more ruthless than that.
