So I like the gillman. Love the gillman. Last of the great Universal Monsters. Or possibly the first given as I'm pretty sure the Devonian period was before we had wolves to make the ancestral curse of lyncantropy, that can't possibly date back earlier than the Pleistocene. I think. When'd dire wolves become a thing? I dunno, I just know fer realz that the Cenozoic was -after- the Devonian and unless vampirism is a supernatural curse that afflicted the earliest air breathing animals, mister gillman is the oldest... ish... I mean, he couldn't possibly because hundreds of millions years old, possibly, I've never read that spin off novel where we learn about the origins of our bad ass finned friend.
