How can we forget about the time that the alien world of Mer was being devoured by an evil liquid known as Dark Water. Only Ren, a young prince, could stop it. His loyal crew of misfits helped him in his journey and would stop at nothing to get the treasures. Pirates of Dark Water first premiered on Fox Kids in early 1991 as a five-part mini-series titled Dark Water. Then came a number of animation tweaks and other changes by Hanna-Barbera.
