Seniesa 'Super Bad' Estrada holds the record for the fastest knockout in the history of female boxing, stopping an opponent in just seven seconds, and unified all five world titles at minimumweight in 2024 to become undisputed champion at 105 pounds. Estrada, nicknamed "Super Bad," turned professional and built a perfect, unbeaten record while collecting world titles across the mini flyweight and light flyweight divisions, and holds the record for the fastest knockout in the history of female boxing, stopping an opponent in just seven seconds of the first round. Estrada became the undisputed female minimumweight champion of the world on 29 March 2024, unifying the WBA, WBC, IBF, WBO, and Ring magazine titles at 105 pounds — a rare feat of complete dominance in her weight class, having steadily accumulated titles across the sanctioning bodies over the preceding several years.
