The Astro Flasher is the Flash Rangers' morphing device. They transform by shouting "Flash On!" While the Flash Rangers themselves are already enhanced due to the fact that each Ranger is either bionic or a superhero, the suits possess prisms which are the key for enhancing their abilities for combat; when these prisms are removed or destroyed, the suits are useless, though certain abilities can be used regardless. The brace also works as a communicator and the prism on it can be used for a "Flash" maneuver to blind enemies.
