He-Man and The Masters of the Universe Series 2002- Episode 13 "Night of the Shadowbeasts"
Beast Man introduces Skeletor to the Shadow Beasts; ravenous, powerful creatures that are only able to travel in absolute darkness. In order to use them, Skeletor has his minions block the vents to a large volcano in the Dark Hemisphere, causing it to constantly erupt and fill the sky with smoke. The Masters soon find themselves having to defend the Royal Palace from the Evil Warriors and the Shadow Beasts, while He-Man heads to Castle Grayskull to defend it from Skeletor. During the chaos, Ram-Man is forced to confront his secret fear of the dark, and ends up trapped underground with Teela during the battle—finally overcoming his fear by courageously defending her from the Shadow Beasts. He-Man battles the Beasts and Skeletor at Castle Grayskull, where a blast of light from the Sorceress dispatches the monsters, and He-Man rips open the volcano with his sword to stop the eruption permanently. Back on Snake Mountain, Skeletor leaves his minions in a room with the Shadow Beasts to punish them for their failure to destroy the Palace.
Moral: Man-At-Arms informs the viewer that everyone has fears, and they can be a good thing.
