Lubo was a Castilon gorg with a skin tone of both brown and green, and his eyes were a light blue color; he resided on the planet called Castilon. During the year 34 ABY, the human named Kazuda Xiono acquired the aforementioned gorg while he was on the Colossus station of that planet, and he then gave him the name Lubo. Xiono's plan was to give the gorg as a gift to his Kadas'sa'Nikto companion, Neeku Vozo, to serve as a pet and to console the Nikto after Vozo had given back his former pet, the young rokkna named Bibo, to the mother of the pet. Inside Jarek Yeager's Repair Station, Xiono showed the eager Lubo to Vozo, and the Nikto received the gorg with joy. Nevertheless, Vozo believed that the gorg was food and he quickly ate him. Vozo expressed his gratitude to Xiono and remarked on how tasty Lubo was.
The initial appearance of Lubo was in "Bibo," which is the twelfth episode of the first season of Star Wars Resistance, the animated TV show; it was broadcast on January 13, 2019.
