Father: Helio Gracie
Son's Stats: 14-2-3
Father's Stats: Record N/A (19 Pro Fights)

Helio invented Brazilian Jiu-Jitsu, but his sons took it to the next level. They helped popularize UFC in the States and used their father's technique to dominate, especially Royce Gracie. He was the first UFC champion and beat guys twice his size (what up, Akebono Tarō?!). This is when there were no weight classes and MMA was too real for TV. Many major events could only be seen on pay-per-view or by households that lived that illegal life and possessed jail-broken cable boxes. Royce's older brother, Rorian, co-founded the UFC and put his father's martial art on a global stage.
