Lord Zedd turns Adam's kaleidoscope into the Scatterbrain monster. His 'brain-scattering' powers are used on Billy, Tommy, and Kimberly, giving them total amnesia! Rocky, Adam, & Aisha attempt to restore their memories using prisms, but they too fall victim to Scatterbrain's attack. Bulk & Skull witness these events, and discover what they sought most: the true identities of the Power Rangers. But will they risk their knowledge of these facts to save the Rangers, and ultimately the world?
