During the Galactic Civil War, a battle between the forces of Tyber Zann and the Hutt Cartel took place on Hypori.
The battle began after Tyber Zann learned of a droid factory discovered by Jabba the Hutt on the planet Hypori. Zann, alongside Urai Fen and several troops of the Zann Consortium landed near the factory and, while approaching the controls of the factory, learned that the Droideka Mark IIs were active and openly firing upon his forces. In order to buy time and avoid unnecessary casualties, Tyber, Urai, and the troops sealed blast doors and retreated. The droids, however, fired on the doors, eventually breaking through.
Eventually, Urai managed to deactivate the Droidekas, after which the Trandoshan bounty hunter Bossk landed and prepared himself to assassinate Tyber, who offered in advance triple what Bossk was being paid so that Bossk would serve the Consortium.
Jabba then landed on Hypori alongside several soldiers for the Hutt Cartel, who opened fire on Tyber and his forces. Urai Fen eventually managed to reactivate the droidekas, this time assisting the Consortium against the Cartel. Consortium forces, supported by the droids, managed to prevent more soldiers from landing.
Jabba, who was still on the planet, was confronted by Tyber, who forced an agreement. In exchange for Jabba leaving without being harmed, Zann would get the planets Saleucami and Hypori, the bounty on his head off, as well as a truce between them.
