Everyone knows an undefeated record in mixed martial arts (MMA) is a rare and precious commodity that can significantly elevate a fighter's career. That coveted zero at the end of a record doesn't just represent perfection—it builds a fighter's mystique, boosts their marketability, and generates unparalleled hype among fans.
However, MMA is an unforgiving sport where chaos reigns, and perfection is difficult to maintain. Losses are almost inevitable, and in all likelihood, someone's pristine "0" will eventually vanish.
