James Warring, born in Florida, had been a world boxing champion in the cruiserweight division for the NABF and the IBF. In addition, he was also an expert kickboxer. That night he had already defeated Jerome Turcan and Erik Paulson by knockout, who were on par with him in weight and size. 
 
It was time for Goliath to face his David. 
 
In the moments that preceded the fight, the commentators of the event declared their very strong impression of Renzo's performance, highlighting the effectiveness and mastery of his technique, something they had "never seen" before that tournament. "Renzo Gracie is unique: the most aggressive Jiu-Jitsu fighter in the world," said another expert. "Absolutely dominant, he brings the fight to himself." 
 
When the battle started, the size difference between Renzo and Warring screamed in the arena. 
 
Renzo took Warring down before any blows could be landed. 
 
On the ground, above the giant, he had the patience to conquer territory without precipitation. 
 
If the first match had the color of anger and the second the color of brutality, now what the audience was witnessing was a surgical fight – almost cold in its extreme technical calculation. Renzo rearranged the geometry of his legs several times, in a relational dynamic that responded to each of Warring's micromovements. As he gradually climbed the immense torso of the downed opponent, Renzo hit the boxer's face with occasional headbutts. In the front position, his chest now level with Warring's face, his arms behind his neck, Renzo promoted the choke with unbearable pressure on the back of his neck, which led James Warring to gave up at 2 minutes and 47 seconds.
 
After 3 battles in a row, all of them won in the first round with amazing efficiency, Renzo Gracie was consecrated as champion of the I WORLD COMBAT CHAMPIONSHIP - and with his victory, Brazilian Jiu-Jitsu (developed, taught and spread by the Gracie family, from of traditional Jiu-Jitsu from Japan) was positioned as the most powerful martial art style on the planet. 
 
"Renzo Gracie is an unbelievably talented man. His technique is very, very impressive... He's unbeatable. A phenomenon", was the comment that ended the broadcast of the event, before the championship belt was handed to Renzo by the boss of the organization, the dandy Christopher Peters. 
 
(The ambition to become one of the biggest MMA championships in the world did not materialize for the WCC: after fighting with his father, who had sponsored the event, Christopher was unable to continue the tournament. That was its first and last edition.) 
 
After this victory, using the money he received and taking advantage of the international projection of his name, Renzo moved with his family from Brazil to the United States, opening his first academy in New York, on 27th Street.
