Yetzer, alongside Leera created the Vore House.

Unlike Leera, Yetzer is considerably more aggressive and less considerate. His hunger is almost equal to hers, but he lacks the restraint and compassion she has that ensures her prey are taken care for. The two are the same species, so they both have the same digestive cycle that allows them to swallow meals safely for 3/4 of their time.

Difference is, He doesn't keep to his safe period and is known to ingest prey regardless of the rules of the vore house.

He is saurossin naga, but he has one primary difference from Leera in terms of biology: HE has a little viper in him. Mamba, in fact. He is part Olive python (large, golden yellow-brown python from Australia) and Black Mamba. Outsides are based on the olive python, insides are the mamba - including his venom. It's powerful, but nowhere near as powerful as Valencia's. his fangs are short, too, so he doesn't often envenomate, but he has the body strength and stretchiness of a python.

So here's Yetzer Mavolim, the devious hybrid naga!
