Francis Zavier Ngannou is a Cameroonian and French professional mixed martial artist and professional boxer who is currently signed to the Professional Fighters League (PFL). He also competed in the Heavyweight division in the Ultimate Fighting Championship (UFC), where he was the reigning UFC Heavyweight Champion at the time of his departure from the promotion. Known for his punching power, Ngannou was widely viewed as the most destructive pure puncher in the UFC's heavyweight division; He ended seven of his fourteen UFC fights by knockout before the two-minute mark in the first round.

The Professional Fighters League (PFL) is an American mixed martial arts league founded by venture capitalist Donn Davis in 2017 and launched in 2018, following the acquisition and restructuring of the former World Series of Fighting (WSOF) promotion in 2017 by MMAX Investment Partners. It is the first major MMA organization in which individual athletes compete in a regular season, post-season and championship, rather than on a year-round basis.
