José Aldo is a Brazilian mixed martial artist who fights in the Ultimate Fighting Championship (UFC). He previously fought in the World Extreme Cagefighting and was the fourth and final WEC Featherweight Champion. As such, he became the first UFC Featherweight Champion after the UFC-WEC merger. Being born into a poor family of humble means, he took up fighting to defend himself against bullies. He eventually earned his black belt in Brazilian Jiu-jitsu from André Pederneiras of Nova União. He later received a black belt in Luta Livre Esportiva under Marco Ruas at Nova União. He is a former two-time UFC Featherweight Champion who has a win record of 26 out of 29 professional fights in his career, and boasts of remaining undefeated for over a decade with a winning streak of 18 fights. He has exceptional skills in Brazilian jiu-jitsu and Muay Thai, and is known primarily for his striking. He has often been called "the greatest featherweight in mixed martial arts history”. The Brazilian film Mais Forte que o Mundo (Stronger than the World) was based on his early life.
