Naga

Naga, In Hindu mythology, it is a being with snake features.

Inside the GTS community
The nagas are represented as women whose upper part (from the legs, in general) is anthropomorphic in appearance and whose lower part is a snake tail.

Many agree that Karbo was the one who popularized this idea, with his work Felarya and with his OC Crisis (a stereotypical silly blonde giantess with her bottom shaped like a snake).
