Thanks to the voice work of Alan Oppenheimer, Mer-Man was a highly memorable character in Filmation's He-Man series. The season two episode "Jacob and the Widgets" features one of my favorite pieces of dialogue from the evil ocean warlord. It's not supposed to be funny, but it is delivered in such an over-the-top and excessively dramatic fashion by one of the most comical-looking villains, that it's hard not to laugh! :)
For your listening pleasure, Mer-Man's theatrical entrance!
