For all that is good, there exists a dark opposite, an enemy with the will to destroy with awesome fury. Despite these adversaries, peace and harmony prevail... all because of six exceptional teenagers who have been uniquely empowered to defend against evil. This is the story of THE POWER RANGERS... in their greatest challenge yet! The evil LORD ZEDD and his wife, RITA REPULSA, in the ultimate attempt to render our heroes powerless, have turned The Power Rangers into children. Now their leader, ZORDON, has no choice but to send them to undercover the power of the ZEO Crystal. It is a mission known as "The ZEO Quest." With great courage, the young voyagers embark on a remarkable journey to their ancestry. Only through the revitalizing powers of the ZEO Crystal can our heroes save themselves and in turn... all of mankind.

A team of teenagers with attitude are recruited to save Angel Grove from the evil witch, Rita Repulsa, and later, Lord Zedd, Emperor of all he sees, and their horde of monsters.
