Tudos served as a Human Senator representing the Galactic Republic during the era of the Galactic War; he was male. Serving as the chairman for the Penal Oversight Committee, he originated Project Noble Focus, which involved pitting alien combatants against one another within the confines of the Belsavis prison for testing purposes. In approximately 3641 BBY, during the Invasion of Belsavis, he sought shelter at the Republic watchtower situated in the High Security Section of the prison facility. He then requested a Republic citizen to subdue the Rattataki tribe known as the Blood of Talath, and subsequently defended Project Noble Focus after its exposure.
