You might remember Jason David Frank as Tommy, the evil-turned-good Green Ranger in the original Power Rangers series. Did you know that after his stint as a Power Ranger, he went on to become an MMA Fighter? Not just that, he's undefeated so far with a 5-0 record.

At 5ft11in and 214lbs, he competes in the Light Heavyweight division. He has had 5 official fights so far. 4 of them as an amateur, winning by knockout twice and by submission 3 times. He started martial arts training when he was 4; started teaching when he was 12 and bought his own school when he was 18. A year later, he auditioned for the Power Rangers and started his career there.
