Leviathan

Leviathan is a two headed piscine demoness with a dichotomy in her anatomy: her humanoid body is divided into two, indicated by the left half of her body appearing white and the right half of her body indigo. Both heads share lengthy fin like white hair styled in a mohawk. Her left head is more humanoid, has webbed ears and electric blue eyes with black sclera and cyan eyeshadow. Her left head's hair has faint pink streaks on it with a black strip and violet gradient interior. Meanwhile, her right is more animalistic, has a longer neck, seafoam green eyes that are lacking pupils, and a fanged, eel like snout. Her right head's hair is bioluminescent, with black streaks on the topside, a dark violet-cyan gradient interior, and green spots scattered across. Leviathan wears a sleeveless high-collar black crop top with a diamond-shaped cutout and twin downward-facing swirls, the right swirl being violet and the left swirl lavender. She wears a black skirt featuring a semicircle-patterned rim bearing the same color split as the swirls. She also wears elbow-length gloves; black on the left and white on the right. Each head wears a light cyan pearl necklace with only the left head wearing pearl earrings, and has a cyan belt to match. Personality While the full extent of her personality has yet to be revealed, Leviathan's two heads appear to have independent personalities. The right head is more cynical and more in charge, while the left head appears to be relaxed and composed. The left head was even friendly to Mammon, unlike the right, and got mad when the right head moved them away from him. The relationship of the two heads is further indicated when Mammon invited Leviathan out after Blitzo's trial; the right head showed active annoyance at Mammon and attempted to ignore him, but her left head seemed to genuinely enjoy being around him, and looked hopefully at the right head, indicating that she hoped that she would allow them to take up Mammon's offer. It is unknown if she shares the same views of superiority as the other deadly sins do. However, she does recognize Satan as her leader and "the law" of Hell. Abilities Bioluminescence - Her hair and eyes can glow, even in dark environments. Skillset Musical talent - During Satan's song, Leviathan and the rest of the Sins can be seen singing in a choir-esque fashion, backing up the former's vocals.
