Grand Admiral Thrawn
In "Heir to the Empire", Lando reprograms C-3PO to sound like Leia in order to hide from Imperials on Nkllon; but the Empire, led by Grand Admiral Thrawn, sees through the deception. In "Dark Force Rising", C-3PO goes to Honoghr with Leia during the Thrawn Crisis to discover what had caused the plight of the Noghri. He is forced to hide with Leia and Chewbacca when Imperial forces arrive overhead, but he later returns with Leia to Coruscant, where she gives birth to Jaina and Jacen Solo. He serves as caretaker to the twins, and later Anakin Solo as well. In "The Last Command", C-3PO also accompanies Han, Lando, R2-D2, Luke, Chewbacca, and Mara Jade to Wayland on a mission to destroy the Mount Tantiss storehouse. Thanks to C-3PO and some Noghri, the party recruits aid from the local population and destroys the storehouse.
