He is an MMA superstar from Sergei's home country. He is in a line of great Russian mixed martian artists like Fedor Emelianenko and Datsik. He is the Russian Darkhorse of the Strikeforce World Heavyweight Grand Prix. He beat that fucking Belorussian Andrei Arlovski, and is going to fight Josh Barnett next! FUCK BELARUS!!!
