37. Giorgio Petrosyan
Italy’s Georgio Petrosyan just might be the greatest kickboxer on the planet today. The Doctor possesses profound technical skills and has magnificent defensive abilities. As a result, he took very little damage against some of the best strikers on the planet. Emigrating from Armenia at the age of 13, he turned professional at 16.

A former K-1 and Glory champion, Petrosyan is now on the books of ONE Championship, after having previously been a champion with Bellator. The Doctor is a contemporary icon. He once went on a forty-two fight, six-year unbeaten winning streak.
