- "Captain Lunker here is in charge of the operation. He will take you to Jan-gwa city."
- ―Captain Gregar Typho
In 21 BBY, Lunker was tasked with watching Jan-gwa city, a small city on the Mid Rim planet of Naboo. During that time, the Sith Lord Darth Sidious tasked the bounty hunter Cad Bane to kidnap Force-sensitive children. One of the targets of the Duros bounty hunter was Roo-Roo Page, a Gungan child living in Jan-gwa city. However, the Jedi Order discovered Bane's plan and dispatched Anakin Skywalker and his Padawan, Ahsoka Tano, to Naboo to protect Page. He and Gregar Typho rendezvoused with the Jedi, Typho told Skywalker and Tano that Page's family had been notified, and introduced Lunker to the two. Skywalker ordered Tano to go with Lunker to Page's house in Jan-gwa city, while he stayed with Typho for sometime. Lunker brought Tano to Jan-gwa city, and soon Skywalker rejoined his Padawan. After a brief fight between Cad Bane and the Jedi, Skywalker and Tano were able to save Page from Bane's attempt to abduct her, and they arrested Bane.
