Cala Maria

Cala Maria is a resident of the Inkwell isle ocean and has romantic feelings for mugman

Cala Maria has a physical appearance reminiscent of a typical humanoid female character. She is a slender mermaid with fairly wide hips. She has pale lavender-pigmented skin, an exposed midriff, a small button-nose, and two scar-like markings on the bicep of her left arm (though how or why she got them is unknown).

On her head, she has a dead, purple octopus with pale lavender eyelids over X-crossed eyes, with a lighter purple coloring and pale pink suckers under the tentacles. The octopus clearly acts as her hair since the three tentacles in front of Cala's face are flipped back over her head, resembling curly hair-bangs in a pompadour, while the octopus's head vaguely resembles a hair bun. Although it appears to be dead, the octopus’s eyes clearly open during Cala’s “summoning” animation, revealing simple, black pupils.

Cala has big, pale turquoise eyes with sea-green eyeshadow and three short, black, triangular eye-lashes each. She also has thin, black eyebrows and light, rose-pink lips.

As a sign of her mermaid status, Cala wears a sky-blue sea-shell bra with no shoulder straps, and her lower body is replaced with a sea-green, fish-like tail with round scales, connected with a water-ripple-like pattern below the waist line. Because only her upper body is seen, it is unknown what the tail-fins look like.

However, in her second phase, Cala Maria gets bitten on her

   belly and shocked by two eels, resulting in a much more menacing appearance—a gorgon-mermaid hybrid, greatly resembling the famous mythology figure, Medusa.

Her once pale-lavender skin turns to a mint-green color. Her fingers become longer due to her fingernails becoming claw-like. Her lips turn an emerald-green color, her tongue becomes forked and reptilian, and her teeth are now quite sharp, forming an eerie, Cheshire Cat-esque grin. The markings on her arm remain unchanged.

Her eyes become menacingly cat-like with yellow sclera and black, slit-shaped pupils, losing the irises completely.

Her tail takes on a more forest-green hue and the scales become sharper and more triangular. Her once sky-blue sea-shell bra is now a green bikini top made from either seaweed, moss, or grass.

The most distinctive part of her new form is the octopus on her head, which has now seemingly fused onto her head and has become a marginally different shade of purple. The tentacles each transform into menacing-looking snakes with lavender, segmented underbellies, yellow, cat-like eyes, and small fangs in their mouths. Only the snakes acting as her bangs are active, while the rest are asleep.

Cala Maria is said to be playful, but not to be trifled with. Cala Maria seems to be a flirty and vivacious being. She appears to have some interest in Cuphead and Mugman, as seen in her intro where she makes a sweet "yoo-hoo!" sound while fluttering her eyelashes and making a pose, and in the ending sequence in which she is staring at the brothers (although, as a siren, she could only be doing it to catch them off-guard as well). Her first phase death message only helps support this. However, she seems to become more cruel after she is forcefully transformed into a gorgon-mermaid, due to electric eels biting her hips and shocking her.

Cala also seems to have a strong connection with fish and aquatic animals, as she can summon them at will to help her, and also use the fish as weapons without them apparently caring much.
