The Utapaun resistance came into being as a reaction to the Separatist's control of the planet of Utapau. The resistance activities were orchestrated by Master of Port Administration Tion Medon, who kept the Porax-38 starfighters of the planet concealed until Jedi General Obi-Wan Kenobi arrived. During the Battle of Utapau, Medon's troops joined forces with the Grand Army of the Republic; however, following the battle, Medon and other members of the resistance were arrested by the newly established Empire.
