Souza was born in Vila Velha, Brazil, into a cafuzo family and was raised in Cariacica, Brazil. Souza had a rough upbringing, and on the day he turned 15, he saw one of his good friends get shot to death. After this event, Souza's mother moved him to Manaus to go and live with his brother and he started training Judo and Brazilian jiu-jitsu when he was 17. He is an eight-time World Jiu-Jitsu Champion, including gold medals in the Openweight class in 2003, 2004 and 2005. His other credentials include the 2005 77–87 kg ADCC Champion and the 2005 ADCC Absolute Division runner-up, only losing to Roger Gracie who outweighed him by approximately 25 lbs. Along with Roger Gracie and Marcelo Garcia, Souza is widely considered to be among the greatest BJJ practitioners of his time.

In 2008, Souza signed with Japanese MMA-promotion DREAM and was scheduled to participate in the 2008 DREAM Middleweight Grand-Prix. In the first round of the tournament, at DREAM 2 on April 29, 2008, he defeated Ian Murphy by a rear-naked choke submission in the first round. This secured him a place in the quarter-finals which took place at DREAM 4 on June 15 where he fought former ICON Sport Middleweight Champion Jason "Mayhem" Miller. The fight went the distance with Souza continuously going for submissions with Miller escaping multiple rear-naked choke, leglock and armbar-attempts while mounting his own offense on the feet.
