leviathan (skullgirls)

Leviathan is the refined parasite who lives inside Squigly in Skullgirls, a proud, fatherly creature who protects her and fights alongside her as a second voice. He looks like a long serpent with a pale body, a crown of fin-like crests, and a wide, toothy maw, rising from her head to strike. Art often shows him coiled around Squigly, glaring sternly at anyone threatening her.
