He-Man and the Masters of the Universe was a popular cartoon and toy in my youth. These NPCs could be found in Shattrath during BC but sadly have all been removed. Pics from Wowhead.
Adam Eternum – obvious reference to Prince Adam of Eternia.
Oric Coe – reference to Orko, whose magic often backfires in the cartoon.
Keldor the lost – a reference to Skeletor (and looks like him too!). There is heavy implication in the cartoon that Keldor was in fact Skeletor. Keldor was Prince Adam’s uncle, brother to the king.
Winna’s Kitten, found in Felwood is the only He-Man reference remaining in game at present! The green tiger look is just like Cringer, Adam’s companion, who becomes Battle Cat when Adam becomes He-Man. Winna’s Kitten is tamable by hunters.
