I am planning a campaign arc where the antagonists are followers of the entity known as Cthulhu from H.P Lovecraft's strange tales. In the end of the campaign I'd like to have the adventurers fight Cthulhu or at least an aspect of cthulhu and I am wondering if there is anything published for d20 system (official or otherwise) with a stat block inspired by the original Cthulhu, or am I just better off making my own?
The following descriptions are from Wikipedia:
The original Cthulhu is described as "A monster of vaguely anthropoid outline, but with an octopus-like head whose face was a mass of feelers, a scaly, rubbery-looking body, prodigious claws on hind and fore feet, and long, narrow wings behind."
Cthulhu has been described as a mix between a giant human, an octopus and a dragon, and is depicted as being hundreds of meters tall, with human-looking arms and legs and a pair of rudimentary wings on its back.
Best Answer
Yeah, the d20 version of Call of Cthulhu is pretty complete. It has a stat block for a demigod version Cthulhu on p.292. You likely don't want to fight Cthulhu himself however...
Try on this CR 20 Starspawn of Cthulhu (a mini Cthulhu) for Pathfinder. Cthulhu himself is more of a god, no stat block.
Update: Cthulhu himself is now found in Pathfinder's Bestiary 4 as a CR 30 creature.
