Akin of course. I used him as a NPC in my games quite a bit actually. I was always going to use Shemeska, but just never got around to it for some reason. Oh well, I guess that's the way it goes. Someday I'll get around to playing another PS campaign. And maybe then Shem will make an appearance...
I was going to vote the Nycadaemons from their cool pictures, but they are not on your list. So I went with Anthraxus (I only remember him and Charon the boatman from MMII).
Charon. It's all about the mythological presence.
Anthrax was close, but I don't know. The band just isn't the same without Joey Belladonna... Oh, this poll is asking about Anthraxus. Sorry, I got confused.
