Shock to the system! The UFC was not prepared for the rapid rise of Raul Rosas Jr. Born to Mexican immigrant parents, the young fighter discovered wrestling in high school and dominated as an amateur, winning IMMAF World Championship gold in Rome at just 14. Nicknamed "El Niño Problema" (The Problem Child), the young fighter stepped into the Octagon with fully formed fighting skills as a Brazilian jiu-jitsu Black Belt, and undefeated 5-0 in the Ultimate Warrior Challenge Mexico. With unstoppable energy, Rosas stole the spotlight as a winner on Dana White's Contender Series, and the rest is history. Rising to the world stage, Rosas set the record as the youngest fighter to sign a UFC contract at age 17 and proved himself as the youngest to win a UFC fight at age 18. Next, he doubled down by claiming three coveted Performance of the Night bonuses. At the age of 20, he made his mark as the youngest UFC fighter to chalk up five wins. Now he wants to become the promotion's youngest champion and put the entire Bantamweight division on notice: "I'm going for the belt!" Better watch closely, because The Problem Child is just getting started.
