UGNAUGHTS CITIZENS: There three several Ugnaught tribes (Irden, Boscut & Isced) present on Cloud City. Some Ugnaughts really look like each other, so it's difficult to tell whether the same Ugnaught appears more than once in the movie.
- Ugloste: Chief Ugnaught.
- Grugnak: Helped the Alliance after the occupation of the city.
- Inkur: Dealmaker for the Irden tribe. Impossible to tell which Ugnaught he is. He has the same face as Uglost and Grugnak. His face appears in 'Galaxy Guide TESB 2nd edition'.
