On December 31, 2004, Ryo Chonan surprised the world with a amazing win over Anderson Silva at Pride Shockwave.
The Japanese fighter pulled a flying scissor heel hook to submit the Spider.
After that, Anderson would loose once more to Yushin Okami due to a ilegal kick and then go on an impressive 17-fight, seven-year undefeated streak.
In the video that follows, you can see Chonan fighting three-time world champion leandro Lo in a no-gi match.
Watch how it all went down.
