Thradian

The Thradians were a species of humanoid sentients from Thrad. They had yellow skin, full black eyes, and annulated appendages that grew from the top of their skulls. Senator Nadea Tural was a female Thradian.

Behind the scenes
The Thradian species first appeared in "Senate Perspective", a comic story written by Martin Fisher and illustrated by Ingo Römling and published in the ninth issue of the  Star Wars Rebels Magazine. For the species' appearance, Römling drew inspiration on a piece of concept art made by Ralph McQuarrie for Star Wars: Episode VI Return of the Jedi.
