In the Direct, Shiver used the pronouns 'uchi' (an informal pronoun usually used by younger women, especially in Kansai dialects) and 'onore' (an archaic pronoun usually used by men).

The Japanese text did not have Shiver use any common first-person pronouns that traditionally connote gender (such as atashi or boku). When referring to herself, Shiver's dialogue used plural forms, as part of the group, or used the passive voice. This did not apply to Shiver's bandmates Frye and Big Man, who were referred to explicitly as female and male, respectively. This was consistent across all languages, and text in languages that require it (French, Italian, and Spanish) did not refer to Shiver in ways that would require inflecting adjectives or verbs for gender. When Shiver was first revealed in the Splatoon 3 Direct, neither the presentation nor other promotional material (such as the announcement dialogue for the Splatoon 3 Splatfest World Premiere and references to Deep Cut on the official website) specifically referred to Shiver's gender. On the back of her head, surrounding a large suction cup on one of her tentacles, she wears a white circular headpiece designed like a shimenawa rope.

She wears a white sarashi under a transparent purple shawl with a large silver octopus head charm with red tassels hanging from it, black leggings with two cuts at the sides, and black thong shoes with red wedge soles. Shiver's right ear is pierced with three shark tooth-shaped earrings. She has the same teeth and ears as playable Octolings. Shiver is an Octoling with pale skin, thin, light-red colored lips, red eyes with light red pupils in the shape of an infinity symbol (like octopuses in real life), one eyelash on her visible eye without the mask-like black marking other Octolings have, red eye makeup under her eyes, red-tinted fingers, blue-purple tentacles with darker tips that curl outwards, and matching-colored triangular eyebrows.
