Now that he sits atop the Rizin Fighting Federation throne, Luiz Gustavo is making sure he remembers the people who helped him climb the mountain.
Last Sunday, the Brazilian lightweight knocked out Ilhom Nazimov just 2:08 into the first round to capture the Rizin lightweight title in Japan. The raw emotion from the Chute Boxe disciple—who trains under the legendary Andre Dida—struck a chord with Japanese fans. As Rizin president Nobuyuki Sakakibara placed the championship belt around his waist, Gustavo broke down in tears and dedicated the victory to two key figures: his late father and former Pride FC icon Wanderlei Silva.
Back home in Curitiba on Wednesday, "Killer" opened up to Sherdog about the win and what those influences mean to him.
"My father passed away when I was 12 years old," Gustavo explained. "The last thing he did for me, just a week before his death, was enroll me in a karate academy."
That karate training became more than just a sport—it was a lifeline. It helped the young boy process the trauma of witnessing his father's murder on their doorstep. Instead of letting anger turn into revenge, Gustavo channeled it into a burning desire to become a champion and make his father proud, "wherever he was."
His talent in karate eventually caught the eye of coach Dida, who quickly realized this wasn't just another promising fighter. Gustavo's laser focus on becoming a champion was so intense that Dida's biggest challenge became convincing him to rest.
"He always had an incredible desire to learn and an extreme work ethic," Dida revealed. "My biggest problem with him was making him understand the importance of recovery. When I learned about his father, everything clicked into place."
Gustavo's rapid improvement in ground fighting prompted Dida to let him make his professional debut at just 18 years old inside Parana's Nightmare Arena. The youngster won by submission.
Between 2015 and 2017, Gustavo fought seven more times in Parana events, finishing every single opponent. His aggressive style and killer instinct—reminiscent of his idol Wanderlei Silva, "The Axe Murderer"—earned him the nickname "Killer" from coach Dida.
By age 22, with eight wins on his record, Gustavo was hungry for a chance outside Brazil. Two weeks before Rizin 12, Bruno Carvalho—originally set to face veteran Yusuke Yachi in the main event—got injured. Coach Dida knew the risk of throwing his fighter into such a high-stakes debut, but Gustavo was ready to prove himself on the world stage.
