Lunker was a male Gungan security captain on Naboo during the time of the Clone Wars. Around 21 BBY, he was tasked with watching Jan-gwa city, a city on Naboo. During that time, Jedi Knight Anakin Skywalker and his Padawan, Ahsoka Tano, came to Naboo to protect Roo-Roo Page, a Force-sensitive Gungan child, from abduction by the Duros bounty hunter Cad Bane. Lunker and Captain Gregar Typho met with Skywalker and Tano in Naboo's capital of Theed. Skywalker ordered Tano to go with Lunker to Page's house in Jan-gwa city, while he stayed with Typho. Skywalker and Tano were later able to save Page from Bane's abduction attempt.
