Trini/Yellow Ranger: Died in car crash in LA on route to serve as a bridesmaid .
Kimberly/Pink Ranger: Became a singer, TV actress, and did an awesome topless scene somewhere.
Billy/Blue Ranger: Disappeared. Apparently hated the rest of the cast for harking on him being gay. Also, built like a tank because he's a better gymnast than Amy Jo Johnson.
Zack/Black Ranger: Became a dance instructor.
Jason/Red Ranger: Supposedly did a stint in gay porn after Power Rangers.
Tommy/Green Ranger/Jesus Ranger: Continues to teach martial arts, using his Power Ranger stint as an ad gimmick. Gained about 50 lbs of muscle and joined the competitive MMA leagues. He's gigantic and covered in tats now. I heard him speak at ACEN a few years back, and he's actually real pleasant.
