Throughout the history of mankind, good has battled evil, and good has always prevailed. The 'Crown of the Gods,' encrusted with seven magnificent jewels from seven galaxies, is said to bestow ultimate power on the wearer. Once written about by the ancients, but dismissed as mythical folklore and long ago forgotten, this legendary crown has been rediscovered. Dark forces from the past awaken and search for the seven missing jewels. If found and placed in the crown, evil will be unstoppable. Power Rangers Operation Overdrive is the fifteenth season and anniversary of the American television franchise Power Rangers. It premiered on February 26, 2007.
