Isi Dawndancer is an exchange student at Monster High and a deer spirit from Boo Hexico. She lived there all her life until a vision notified her of Monster High and urged her to study there.
Isi is a peaceful girl who simply adores dancing, so much she might breakout into a dance sequence any moment. An animal-loving and flirty girl, she is playful, yet wise when needed, and gives a big importance to her herd and its rituals. She is very willing to share parts of her culture with other students through teaching them dance, demonstrating enthusiasm for doing so.
She has brown skin with a big white spot on her face fading into her skin, long straight turquoise hair, and a deer-like nose as well as ears and antlers. Her eyes are brown, and she has white little dots that may be freckles, on her cheeks and forehead. She wears a dull-sepia colored headband and an orange necklace. She wears a red, long-sleeved shirt with Aztec designs and long, black pants with the same designs. She has teal ruffled shoes and her feet are also hoofs with heels in the back of the feet which are also hoofs.
Isi has a grandmother, who she states is very wise, but can get mad if someone ticks her off.
Isi is best friends with Twyla, whom she met in Boo Hexico, when the latter failed a shadow jumping exercise of long distance. The two quickly become friends, as Twyla helps Isi out with her mysterious dreams.
Additionally, she is also friends with Gilda Goldstag, another deer creature at Monster High, which is assumed to be their main friendship link.
Back in her homeland, she also has an acquaintance she despises, Coyote, a trickster who has no sense of limits.
