A while back I made this NPC generator for a Finnish role playing game called Praedor. I received pretty good feedback for it, so I decided to modify the same tool to generate random monsters for Call of Cthulhu as well. I thus present to you, the Call of Cthulhu Creature Generator:
It’s pretty cool. And it’s pretty simple. Choose the monster you want, click “generate” and it’ll roll out the creatures for you. You can also set the desired level in order to create above or below average creatures. It’s a shame I wasn’t the first the blog about it, Cthulhu.de beat me 
There’s some discussion about this tool also on the awesome yog-sothoth forum. Leave a comment below for any feedback or suggestions. I’m always open to new ideas, especially if they are easy to implement 
Thanks for your comment and the editor is really useful! Keep on the good work and thank you for your kind words about cthulhu.de
(Sorry my english is not so good. Reading is simple, but writing… kinda difficult
Very kool program!! A few questions could attacks skills damage be added to it? I was wondering can the program be downloaded for personal use? I been wanting a program that i could use as a BRP,coc monster database. Anyways keep up the good work.
Hi, glad you liked this, sorry for very late reply. Sorry, I don’t have time to add attack damage for each skill and creature, also I no longer have the rule book, so I couldn’t do it even if I wanted to… There are many many apps that you can download for character creation, but I’m not sure about a monster database as such. Anyways, this will only be an online app, don’t have any spare time
I am fond of this program and use it for all my stories, but I frequently do not have access to the internet. Is there any way that I might be able to acquire the program file?
