Ashley was a recurring character during the beginning of the Turbo Era. She was an Angel Grove High School Cheerleader and was seen helping the terrified citizens of Angel Grove get to safety during one of Divatox's major attack on the city. Ashley was chosen by Tanya Sloan to take her place as the Yellow Ranger, taking over control of the Dune Star TurboZord and later gaining access to the Star Racer RescueZord.
When the Power Chamber was destroyed by Divatox and the defeated Power Rangers received word that the planet Eltar, home to their original mentor Zordon, had fallen to evil forces, Ashley and the other three new Turbo Rangers - T.J., Carlos, and Cassie - left Earth and Justin (who decides to stay with his dad) for outer space in a NASADA space shuttle, powerless but ready to fight to save Zordon.
Ashley and the other Rangers then met Andros, the Red Space Ranger, on the Astro Megaship, and she was given new powers as the Yellow Space Ranger, who later commanded the Mega V-4 (Saucer) Zord. When the Space Rangers returned to Earth, she enjoyed showing Andros her hometown. She discovered that he was telekinetic. Ashley offered to teach Andros billiards if he taught her how to use telekinesis. She would get distracted during the lessons, and thus never did get the hang of it.
She shared a love interest with Andros, who returned to Earth with her after the final battle.
Later on, Ashley and the other Space Rangers received a distress signal from Alpha 6 about the Psycho Rangers return and the Galaxy Rangers were in trouble. The Space and Galaxy Rangers fought and destroyed the Psycho Rangers.

- She and Cassie were the only Turbo Rangers to keep their colors when they became Space Rangers.
- She was originally suggested to share a love interest with Carlos, but that idea finally was rejected, and they only remained as friends.
