S01E01 Into Etheria
Sorceress discovers a gateway to another world. She sends Prince Adam and Cringer in to investigate. They find the new world to be enslaved by Hordak and his second in command, Adora.
Catra kidnaps the Sea Elves of Seaworthy to bait a trap for Adora and Sea Hawk. Meanwhile, Adora is afraid Sea Hawk likes She-Ra better than her.
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.
