Art done by my Mate:

Malice, as you can see, is a Naga. Tik, held in his arms center page, is his mate. (my irl mate's character)
The yellow and blue coloring changes with mood to either grey and brown, or red and black. The jaw unhinges for consumption of meals, and the tenctacles from the wrists inject poison into open wounds that shrinks the victim to a manageable size for devouring prey. The tentacles behind the head are for reproduction. Each tendril carries a single egg, which in turn becomes a Naga after self fertilization in a female's womb. The offspring will have no traits from the host other than eye-color, afterwards leaving soon after being born.
