Kaya is a young girl from the Nimiipuu or Nez Perce tribe living in the pre-contact Northwest. Themes in her core series focus on leadership, compassion, courage, and attachment. Chronologically, Kaya's adventures are the earliest of the historical characters. Kaya is depicted as brave and outgoing, but careless and thoughtless, and wants to be a leader of her people. Her role model is a female warrior named Swan Circling. Created in collaboration with a consultation team that included representatives from the Nez Perce tribe, Kaya is the only Native American doll made by American Girl to date. Kaya is the only doll in the series not to show teeth, per tribal custom.
