Mok Shaiz was an Ithorian male who was the mayor of the city Mos Espa on the planet Tatooine around 9 ABY. Following Boba Fett's takeover of the palace and criminal empire of Jabba the Hutt, Shaiz and Fett came into conflict after the latter failed to pay him tribute, instead having expected the Mayor to do the same to him. When Fett subsequently fell victim to an assassination attempt, the new crime lord visited Shaiz, believing he was was responsible, though the Mayor deflected both the accusation and the threats made by Fett.
