Tee-Six, a droid, served alongside Amilyn Holdo, who previously held the position of senator apprentice. They were both on the Rebel Alliance arms–smuggling vessel, the Candor, at some point between approximately 2 BBY and 4 ABY. Despite Holdo not always being pleased with its performance, Tee-Six aided her in duties such as watering the vegetation on the ship and monitoring the various systems. During an assault on the ship by an Imperial Star Destroyer, Holdo questioned the droid regarding the status of the lighting, but Tee-Six remained silent. Following the assault, the Candor managed to flee, suffering minimal losses, largely due to Holdo's adept leadership.
Tee-Six was characterized by its white exterior, a red detector, and its fixed position on the Candor's wall.
Tee-Six made its debut in "The Bridge," a comic narrative featured in Age of Resistance Special 1, a one-off comic released by Marvel Comics on July 31, 2019. G. Willow Wilson penned the story, while Elsa Charretier and Nick Filardi provided the illustrations.
