The Ol' Soul Eater apparently has scales in Lovecraft's version as well. Figures, since he's a critter of the depths. Seems to kind of slouch, though. He needs to work on his posture.
Incidentally, I learned something new today. At least according to Lovecraft collaborator and mythos author August Derleth, the name of the lord of R'leyh should actually be pronounced "'THOO-loo," not "kuh-THOO-loo."
The "C" is silent. According to Derleth, anyway. But of course, Derleth thought that the Elder Sign looked like this:
and in one of his stories suggested that it was something like a swastika (which, given Lovecraft's notorious racism and anti-Semitism, was unfortunate, to say the least).
This confusion would obviously become a significant issue should one find oneself surrounded by hostile Deep Ones.
