Casiss Midagatis was a Felucian male, specifically the village elder for a nysillin farming community located on Felucia. In the time of the Clone Wars, the Ohnaka Gang posed a threat to his village by demanding a share of their nysillin production. To protect his people, Midagatis enlisted the services of four bounty hunters: Sugi, Embo, Rumi Paramita, and Seripas. Subsequently, after their vessel experienced a crash landing in the vicinity, the Jedi Obi-Wan Kenobi, Anakin Skywalker, and Ahsoka Tano also offered their assistance. Following their contribution in training the villagers to defend themselves and successfully overcome the Ohnaka Gang, Midagatis expressed his gratitude to both the Jedi and the bounty hunters before departing to supervise the village's reconstruction efforts.
The character of Casiss Midagatis was voiced by Gregory Baldwin in the Star Wars: The Clone Wars episode titled "Bounty Hunters."
