He-Man and the Masters of the Universe (1983) - 1x54 - The Return of Granamyr- Followmy.tv

Granamyr summons He-Man to Darksmoke, and He-Man follows his call accompanied by Man-At-Arms, who wishes to thank Granamyr for helping save his life (in "The Dragon's Gift"). Granamyr explains that a young dragon called Torm has fallen in love with a human princess, Lyra, and wants to become human in order to marry her. But Lyra's father, Brindle, will only allow any man to marry her if he passes a series of tests. Only a human can take these tests, and Granamyr wants He-Man to take them on behalf of Torm. He-Man agrees, but as he undertakes the tests he faces danger from an evil sorcerer called Zim, who wants to marry Lyra himself.
