This is one of the most vicious roundhouse kicks ever

Fatality!

This might be the most vicious way to end a kickboxing fight I have ever seen. This guy went all out and full horizontal to knock his opponent out. This is a roundhouse kick that Chuck Norris can be proud of as it completely knocked this guy unconscious. There was the sweat flying off him, some blood came out of his mouth and he completely collapsed to the mat. That is where Mortal Kombat got its "Fatality!" from for sure.
