Austin St. John launched to stardom in 1993 with his first role as the original Red Ranger, Jason Lee Scott, in the children's television series Mighty Morphin Power Rangers. Like his character, Austin has a background in martial arts, having practiced since the age of five. He holds multiple black belts and has been practicing martial arts for over 40 years. He published his first book in 1996, Karate Warrior: A Beginner's Guide to Martial Arts to inspire kids with his love of martial arts, and reprised the role of Jason several times throughout the Power Rangers franchise. Then, with three seasons under his Morpher, Austin left Hollywood.
