Inspired by this post complaining about turning proper names into generic creatures, Lord Gwydion statted up saurons for use in your game. Even though I complained about speciation and genericization previously, I have the urge to turn other proper nouns into monsters. Heck, I've been guilty of it in the past. But I think all the obvious "proper" monsters have been taken. Didn't someone already do a write-up for "grendels"? Certainly, the vampires in original D&D could be renamed "draculas", since they bear more resemblance to Count Dracula specifically than to ordinary vampires. Chimeras? Done. Hydras? Done. Cereberoi? Scyllas? I think I've seen each of them written up somewhere. Talos got turned into iron golems, Frankenstein's monster became flesh golems. Beorn from The Hobbit got turned into "were-bears", the Balrog from LotR became Type VI demons; I suppose someone could do "gollums", "shelobs", and "gandalfs".
They haven't been written up for a game (as far as I know,) but the new TV series Grimm turns individual creatures from Grimm's fairy tales into generic types: the big bad wolf becomes blutbads, the three bears become jagerbars, the three little pigs become bauerschwein (I'm anglicizing the names, because I'm not sure what some of the plurals should be. Blutbaden?)
Anyone have any good ideas for "proper" monsters?
