Ashley Hammond was picked by Tanya Sloan to succeed her as the second Yellow Turbo Ranger of the Turbo Rangers.

After Divatox's crew destroyed the Power Chamber and her Turbo powers, Ashley became the Yellow Space Ranger of the Space Rangers.

During the events of Power Rangers Lost Galaxy, Ashley and the other Space Rangers return helping the Galaxy Rangers against Trakeena and the resurrected Psycho Rangers.

Retroactively, she is also referred to as Turbo Yellow Ranger and Space Yellow Ranger or In Space Yellow Ranger - variations on her in-show labels, though the latter is more in reference to the show itself than a proper label.

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. On Ashley's birthday, the monster Body Switcher had managed to make Astronema look like Ashley, and vice-versa. Ashley managed to escape, while disguised as Astronema and warned the other Rangers about the real Astronema posing as her. During battle, Andros got her Morpher, but had trouble telling who was the real Ashley, and he gained an idea, knowing only him and his fellow Rangers know how to activate the Morphers, he used that to his advantage, and gave Ashley her Morpher back.

She shared a love interest with Andros, who returned to Earth with her after the final battle in Power Rangers in Space.
