Austin St. John (Jason Lee Scott, Red Ranger)
Born Jason Geiger, Austin St. John played the original Red Ranger, but left with two other Rangers midway through Season 2 — rumor has it, over a pay dispute. That didn't stop him from guest starring later, though! He was also the Gold Ranger in Power Rangers: Zeo. Author of the book Karate Warrior: A Beginner's Guide to Martial Arts, he's currently an EMT and firefighter on the East Coast, according to his website.
Dude still hasn't forgotten his Red Ranger roots, though; he'll be a guest at Power Morphicon this August.
