The Hutts were famous for their ruthlessness, and success in the underworld. Many Hutts would ransack ships for their load. As masters of the criminal underworld, they would steal, cheat, and murder without regret. They often hired smugglers such as Han Solo to transport illegal spice. They would typically have a fortress of some kind, often on remote planets, such as Jabba's Palace on Tatooine. Hutt fortresses would usually be guarded by selected mercenaries or bounty hunters. Gamorreans and Weequay were common species to fulfill this duty. Leading an organization of crooks and scum meant competition. The Hutts that got involved with criminal activity were often killed, or enslaved. Only the more cunning and clever Hutts, like Jabba, stayed at the top of the food chain. Some Hutts, including Jabba, had such an influence that they actually controlled entire planets.Notable for being a very egocentric species, Hutts on their homeworld believed themselves to be the center of the universe akin to deities to some of their subject races. In fact, their survival after the destruction of their homeworld of Varl led them to believe that they were greater than the gods that they had once worshipped. Their success in life was directly proportionate to their ego which in turn were known to be immense. In addition, they were known to be highly manipulative creatures and considered experts in getting others to do their bidding.Young Hutts when they grew to adulthood often gained corpulence which was a trait that was seen as a sign of prestige and power As such, the bigger the Hutt, the more power it acquired which was not only from its peers but from non-Hutts as well. Within Hutt society, those rare individuals that were capable of growing hair on their bodies were considered mutants and were seen with disgust which was rarely disguised.
The Hutt Empire was powerful in its own right, comprising a large area of space on the Outer Rim Territories, and Huttese, the native language of the Hutts, was widely spoken by subjugated races. But many ambitious Hutts moved to worlds outside Hutt Space to become overlords in organized crime within the Galactic Republic, Galactic Empire and New Republic. All Hutts had a given name, which was supported by their clan name and surname (such as Jabba Desilijic Tiure and Borga Besadii Diori). However, few outside Hutt society were aware of various Hutts' proper names and commonly replaced the clan and surname with "the Hutt", as in "Jabba the Hutt" or "Gardulla the Hutt," although it is doubtful the Hutts minded. Hutts were furthermore divided into castes, including H'uuns.
