There were older drawings of the character but I'm going to still to the latest version, and cause I don't entirely like most of the older pics of her that much.

One of Riis's odd characters, Arva.She is a character drawn only for her body, fetishes, and not for her face/looks, so yes if you've came here thinking this was supposed to be. The oversized monster is nasty, gluttonous, slothful, greedy, a pleasure whore, bred to be a breeding, bred to be strong/musclebound, is a capable of using psychic power to fly, and has a fetish for stuffing her bellies, whether it'd be through over eating or through pregnancy among other methods. That's pretty much it about her in a nutshell.
