Cosmo “Good Boy” Alexandre

About Cosmo Alexandre

Life could have been very different for decorated Muay Thai and Kickboxing Champion Cosmo Alexandre.

Like many Brazilians, “Good Boy” played football in the streets from a very young age. He even had a blossoming career as a professional footballer, but he gave it all up at the age of 19 to pursue Muay Thai instead.

Although his family disapproved of his new career, Alexandre remained determined to make a name for himself in the ring and even moved to Thailand to live and train. It turned out to be one of the best decisions he ever made, as he went on to establish a phenomenal combat sports career, winning numerous titles in both Muay Thai and kickboxing.

Known as one of the best strikers Brazil has ever produced, Alexandre has faced some of the biggest names in the striking arena, including the likes of John Wayne Parr, Sakmongkol Sithchuchok, Yodsanklai Fairtex, and Giorgio Petrosyan. He now hopes to continue his great success at the highest level in ONE.
