Hay-Zu, who styled himself as the Big Hay-Zu, was a male Patitite native to the planet Patitite Pattuna. During the Clone Wars, he ruled over his species as a dictator, sending their children to fight his wars. When Patitite scouts captured the droids R2-D2 and C-3PO, Hay-Zu was brought to see them. He demanded that the droids leave his planet, but was killed when R2 fell on him.
