Ivanildo “Monstrinho” Delfino

Status: Former ONE Athlete

Life was difficult for Jungle Fight Flyweight Champion Ivanildo Delfino growing up along the Amazon River, and his family made a living from traditional Marajoara crafts and fishing. He began training in Brazilian Jiu-Jitsu at the age of 19 as a way to defend himself in such a rough environment, but realized that it could lead to a better life for his family and decided to make the transition to mixed martial arts.

Delfino dedicated himself to training and even moved to a different state in search of better coaching. Training alongside some of the top mixed martial artists in Brazil at the Marajo Brothers gym, it was a choice that paid off handsomely.

Nicknamed “Monstrinho,” he tore through the competition in Brazil, putting together an undefeated 8-0 record with six finishes to become a regional champion. This brought him to the attention of ONE Championship, where he will now get his chance to shine on the global stage as part of the ONE Flyweight World Grand Prix
