Tabba served the Rebel Alliance as a fighter pilot. She was assigned to the Mon Calamari Star Cruiser named Defiance throughout the Galactic Civil War. During the year 3 ABY, Tabba met her death in combat close to the Japai system. This occurred in the months preceding the Battle of Endor. Fellow pilots Kraigg and Lady Blue also perished in the same action. A joint funeral was held to commemorate the three fallen Rebels.
