The most intimidating knockout artist in the combat sports, Francis Ngannou, is a Cameroonian-French mixed martial artist.

The former Ultimate Fighting Championship (UFC) in the heavyweight division, since March 2021, after defeating Stipe Miocic in UFC 260.

Ngannou is known for his formidable striking power and holds the world record for the most powerful punch, with a punch equivalent to 96 horsepower, which is equal to getting hit by a Ford Escort going as fast as it can, and more powerful than a 12-pound sledgehammer swung full force from overhead.
