This species first appeared in the 2019 sequel trilogy film, Star Wars: Episode IX The Rise of Skywalker. They were originally designed by concept artist Jake Lunt Davies, though according to Davies, the design was changed a bit by Neal Scanlan as it was translated into live action, potentially due to time pressures or practicalities. In both Episode IX and Andor, the members of this species were portrayed by Kiran Shah.
