Ultima is a striking kaiju girl with long silver-gray hair streaked with black, glowing orange eyes, and sharp fangs. Pale-skinned and athletic, she wears a black crop top with striped sleeves, matching shorts, striped thigh-highs, and gloves.

Athletic and imposing, she stands with arms raised amid crackling energy, radiating intensity and raw destructive force in her hybrid form. Calm, composed, and stoic.

A cunning and theatrical queen with a sharp tongue and sharper claws, she rules through charm, intimidation, and calculated cruelty.

With a subtle, judgmental side-glare, her sleek design gives off an eager-to-please, "not like other girls" energy as she tries hard to stand out.

Rodan is a fiery, bird-like humanization with tanned skin, fierce amber eyes, and short crimson hair topped by two large, backward-curving crests.

Outfit-wise, she wears a red layered jacket with feathered shoulder accents, dark arm guards, a short white pleated skirt, and dark tights.
