Uba IV, a planet in the Mid Rim, was the home of the Ubese people following the destruction of Uba III. At the end of the first Battle of Uba IV, it was heavily poisoned and irradiated. A millennia later, in 22 BBY, it joined the Separatists, and was the site of a droid manufacturing plant. Clone Commander Gree faced virus-loaded Octuptarra combat tri-droid and regular tri-droids on the planet. Even after the finish of the Clone Wars, the Ubese guarded their world with both droids.
