As I said in a previous post the He-Man and the Masters of the Universe Series Guide was given to stations wishing to pick up the show for broadcast. Like the Series Bible it contains lots of character histories, early conceptual drawings, and episodes that were never made. Here I present the earliest design of Skeletor's pet Panthor! You will notice immediately that the original design was intending for Panthor to be a direct clone of Battle Cat minus the stripes. You will also notice the odd color scheme; an actual black panther, with purple armor. Fortunately the Filmation character designers saw sense, ditched the helmet, and made him the evil, vicious, purple panther we all know and love...or should that be fear?!
