She-Ra: Princess of Power
She-Ra, He-Man's twin sister, is leading a group of freedom fighters known as the Great Rebellion in the hope of freeing their homeworld of Etheria from the tyrannical rule of Hordak and the Evil Horde.


She-Ra and Mermista free a baby horned whale from Hordak's capture. They take it back to Mermista's father's undersea kingdom, Salinius. But they are unaware Hordak has attached a limped spy device to the baby whale.
