I'm new to DF and modding, so I introduce my first ever mod, that adds 6 types of cacodemons (I'm pretty sure you all know who they are)
- Malwrath - lesser yellow-skinned cacodemon
- Cacodemon - classic one
- Wretched - blue skinned greater cacodemon
- Brown Cacodemon - has only two horns, but has two hands
- Nightmare Cacodemon - like brown, but red and makes ambushes
- Aberrant Cacodemon - has small tentacles and 4 eyes

As a template and "tutorial" I used beholders from Genesis Mod by Deon
