Tito Ortiz vs. Evan Tanner
Artist: UFC 30
Tito Ortiz successfully defended his light heavyweight title against Evan Tanner with a KO less than one minute into the fight. If you look closely, you can see Tanner was out cold right after the slam. Anyone can knock out another person with their fists, but to get a KO by essentially crushing your opponents diaphragm, as Ortiz did with a body slam in this bout—that's just beasting on a whole other level.
