He-Man and The Masters of the Universe - Ep 12

He-Man and The Masters of the Universe Series 2002- Episode 12 "Mekaneck's Lament"
Mekaneck begins to feel inferior to the other Masters due to his abilities, despite Adam's attempts to encourage him. An old man approaches Mekaneck and claims to grant wishes, offering to give him new abilities in exchange for an amulet hidden away in the Sands of Fire. The Sorceress summons Adam and warns him about the return of Count Marzo—a sorcerer who nearly conquered Etheria using his magic amulet, but was stopped by the army of Adam's grandfather, King Miro, and the Elders of Eternia, who transformed him into an old man and banished him to the Dark Hemisphere. Mekaneck successfully recovers the amulet and returns it to Marzo, who retreats and uses it to recover his true form. With two transformed rat creatures, Marzo rampages towards the Royal Palace for revenge, defeating He-Man and the Masters with his magic, and unleashing a poisonous cloud of gas to render everyone unconscious. Informed of the chaos by Orko, Mekaneck joins the battle and uses his neck-stretching abilities to avoid the gas and snatch the amulet from Marzo, allowing He-Man to throw it into the horizon, stopping Marzo's plans. At the palace, Mekaneck realizes that Adam was right about him all along; while, in the ocean, Marzo's amulet is shown to still be active.

Moral: He-Man tells the audience that everyone has unique talents and abilities, and rather than try to be like others, they should be the best they can be.
