Whoa, what just happened! Mere seconds into their much-anticipated heavyweight showdown at UFC 249, Francis Ngannou stepped into the Octagon against Jairzinho Rozenstruik and reminded everyone who might of forgotten about just how scary he truly is. Nobody has superhuman striking power in this sport quite like the Predator, and he made that abundantly clear just 20 seconds into the opening round.

Down goes Bigi Boy! OUT goes Bigi Boy. Finishing helpless foes early with hellish strikes is just what Ngannou does.

Rozenstruik has played the part of exciting up-and-comer in the heavyweight class, and was buoyed by a recent last-gasp KO win over longtime bruiser Alistair Overeem in December. Ngannou is simply a different beast -- and "beast" is exactly what he is -- and showed his extra level of class Saturday night with a few unrelenting hammer blows.

The soft-spoken Cameroonian let his fists do the talking on the night. And they screamed for a title shot loud and clear.
