Princess Adora raises her magic sword and becomes She-Ra, the most powerful woman in the universe, to aid her friends in defeating the Evil Horde so their planet Etheria can be free.

The kidnapped daughter of Queen Marlena and King Randor of Eternia (characters from He-Man and the Masters of the Universe), Princess Adora grew up on Etheria. There, she lead an evil army until the day her long-lost twin brother, Prince Adam (He-Man), came to tell her who she really was. As her alter ego, She-Ra, the princess protects Etheria by fighting the forces she once worked for.—Max Vaughn
