Can anyone researching on hindu mythological demons?

Hi guys,
I have said it so many times, that i am curious child. So i love hopping from one subject to another, just to get all the juices, hehe currently, i just read about kalki and kali , don’t get confused with kali and kaali, kali is demon from hindu mythology and kaali is goddess. And researches on apsaras like, ur vasi and rati. I would like to know more about hindu mythological demons, i mean kinda unusual kind of demons. So if you know something about this topic. Kindly pm.
