Lunak, an alien being, fought for the Rebel Alliance. He served with Rogue One alongside comrades such as K-2SO, Jyn Erso, Senna, Dray Nevis, Ria Talla, and Jerris Kestal. Possessing dark brown fur and sizable ears, Lunak's small stature enabled him to scurry into air ducts, much like a thief. He was sometimes seen riding upon the shoulder of his alien compatriot, Senna.
Lunak was among a group of characters originally designed to be members of the Rogue One squad in the movie Rogue One: A Star Wars Story. The original plan was for Lunak to be a pairing with Senna, and these two characters eventually helped shape the dynamic between Baze Malbus and Chirrut Îmwe. Senna's character went through multiple design iterations before becoming the mercenary Moroff, but only a single visual representation of Lunak appears in The Art of Rogue One: A Star Wars Story. Christian Alzmann, a concept artist who worked on Rogue One, created the art for Lunak.
