Most will agree that the majority of Hordak’s science experiments go horribly wrong. However, during one of the rare times that he managed to capture She-Ra he was able to secretly extract her DNA and used it to create a clone of her. Instilling it with DNA from other creatures, once it reached maturity, it used it’s super-natural powers to break free. Feeling it was an abomination of science it took refuge in one place not many could follow, the depths of the Etherian Swell: A dangerous and deep sentient ocean. Over time it honed it’s abilities and took the water on as an attribute, becoming Sea-Man! It’s no coincidence that he bares a striking resemblance to He-Man, as She-Ra and He-Man are siblings. And not only in power, but he also wields the mystical Sword of Shale!
