  • Origin of nickname: “I got the ‘Khaos’ nickname when I was 13 because I always used to fight and get in trouble when I was little and people started calling me that because they said every time I’m around I’m causing chaos. I put the K on it to make ‘Khaos’ because my name starts with a K. The ox came about from wrestling around and slap boxing with my friends. They'd joke and say I’m strong like an ox, so when I started fighting I just came up with ‘Oxfighter’ because I’m a fighter and it’s got a ring to it.”

 When and why did you start training for fighting? I started training in September 2013 and had my first fight three months later. I started because someone seen me fight and told me that I had it. So I found a BJJ gym and just fell in love after my first bout. I jumped into the sport with some blind faith but I put the work in and now I got people all around the world telling me it’s my time.

What ranks and titles have you held? I'm three-stripe blue belt in jiu-jitsu and I have the professional TWC super lightweight championship.

Do you have any heroes? Jay-Z, Meek Mill, Jon Jones and Kobe Bryant rest in peace.

What does it mean for you to fight in the UFC? It means the world to me to be in the UFC and I'm excited to be great and do great things.

Did you go to college and if so what degree did you earn? Yes, I went to college but I ended up dropping out and started training full-time.

Specific accomplishments in amateur competition? Amateur MMA champion

Specific accomplishments in pro competition? I fought in Beijing, China and won in 24 seconds with a knockout. I won my first professional title at 5-1 against a vet with over 35 fights.
