He-Man and the Masters of the Universe - Season 2 Episode 52 Beauty and the Beast

Skeletor captures Teela and Orko, and sends them to be imprisoned in the dark, dismal kingdom of Morragor, ruled over by an enslaved monster in thrall to Skeletor. But the monster, despite his gruesome appearance, comes across as noble and friendly, and treats his captives with utmost dignity. As He-Man journeys to rescue his friends, Teela, seeing the monster's true personality beneath the surface, encourages him to break himself free from his unwilling devotion to Skeletor.
