In the fictional Star Wars, Wat Tambor was the Foreman of the Techno Union. Because he wanted to escape the choking bureaucracy of the Galactic Senate, he joined the Confederacy of Independent Systems and supplied his droid armies to them. He also hosted the Separatist meeting at one of his factories in Geonosis. He is entirely dependant on technology to survive and is encased in machinery.

During the Clone Wars, Wat Tambor was in charge of creating the army Grevious needed from the Nelvaanian braves. But he was killed by Anakin Skywalker as the first victim of the "Force Choke".
