Beidlo, a young boy, spent his childhood with his mother and father on the desert planet of Tatooine. After his parents were murdered by the savage Tusken Raiders, he was taken in and cared for by the B'omarr monks. Later, Mammon Hoole journeyed to Jabba's Palace alongside Tash and Zak Arranda with the intention of studying the B'omarr monks. Beidlo shared his knowledge of the B'omarr monk culture with Tash and Zak. Over the course of Hoole and the Arranda children's extended stay, Beidlo developed a friendship with Tash and Zak, finding himself entangled in one of Jabba's nefarious schemes. Ultimately, his brain was transferred into a monk brain spider, and one of Jabba's underlings utilized his physical body.
The character of Beidlo is a Tuckerization, named after Mike Beidler, who served as a continuity editor and military tech advisor for Star Wars.
