Heylo. So I've come across 3 different types of "snake people" in different mythology researches. 1 is relatively known and is a lamia. Lamias are half and half, being human from the waist up, and from the waist down, they have a snake tail. Lamias are only female, there are no male lamias. For the most part of what I've seen, they can be good or bad but are more commonly bad considering they kidnap dudes to continue the species. 2, is a naga. Nagas are basically just snakes with human heads, which is a little creepier to imagine... But nagas can be male or female. Nagas are not good or bad, it depends on the naga, same as people. Nagas are more eastern while lamias are more western. And 3, the Gorgon. The most well-known Gorgon is Medusa. If I remember correctly, there were 3 Gorgons in Greek mythology. 2 were immortal and born Gorgons, meanwhile Medusa was cursed by a god (or goddess...idk). Mainly human, uglier features and then snakes for hair. I think they all had the 'turn to stone' ability, maybe just Medusa.
