He is mostly known for his time in Pride Fighting Championships. Cro Cop has also fought for the UFC, K-1, RIZIN and Bellator. He is widely considered as one of the greatest kickboxers and MMA fighters of all time.
Cro Cop is the 2006 Pride Open-Weight Grand Prix Champion, the 2012 K-1 World Grand Prix Champion and the 2016 Rizin Openweight Grand Prix Champion becoming the second fighter in the world to win mixed martial arts and kickboxing championships and tournaments. He is also a former IGF Champion. His nickname, Cro Cop, short for "Croatian Cop", comes from his membership in the Lučko Anti-Terrorist Unit, Croatia's elite Police Special Forces tactical unit.
Cro Cop's signature move was his lightning-quick left high kick, once famously described as "right leg, hospital; left leg, cemetery." He was a successful amateur boxer and medalled numerous times in international competition, and was also a member of Croatia's world team when he competed at the 1997 Amateur Boxing World Championships.
