Mercious Bragg was a Human male who served as a sergeant in the Intelligence Division of the Royal Naboo Security Forces during the time of the Galactic Civil War. Sometime following the Battle of Yavin in 0 BBY, a section of Theed fell victim to a terrorist attack. Sergeant Bragg, who often conducted business in the capital's local cantina, was tasked with discovering the identity of the culprits. With the help of a trooper loyal to the RSF, Bragg investigated the headquarters of the four major criminal organization on Naboo, namely the Skaak Tippers, Borvo the Hutt's criminal empire, the Darkwalkers and the Mummers. Sergeant Bragg eventually concluded that the Mummers were responsible for the attack. Following this revelation, the Royal Naboo Security forces conducted a raid on the Mummer bunker, neutralizing the Mummer's ability to enact future terror attacks.
