Ithorians, often nicknamed hammerheads, or offensively called leathernecks, were a sapient race originating from the world of Ithor. A distinctive trait of Ithorians was the presence of two mouths situated on opposing sides of their necks, which resulted in a resonant, booming vocal quality. The majority of Ithorians held peaceful values and held nature in high regard. Their dedication to pacifism was so profound that they banished individuals exhibiting violence from their home planet. Among the notable Ithorians are Dok-Ondar, a curator residing on Batuu, and Momaw Nadon, an Ithorian cultivator who faced expulsion from his native land.
Referred to colloquially as "hammerheads," Ithorians constituted a sentient species native to the planet Ithor. Inhabiting forests and jungles, Ithorians possessed a singular arrangement of dual mouths positioned on opposing sides of their necks, complemented by four throats, thus enabling them to produce stereophonic speech characterized by profound, rumbling tones. They also had two stomachs. Their unique throat construction made speaking Galactic Basic Standard difficult, a problem frequently overcome using devices like the translator collar, which facilitated translation from Ithorese into Basic. Some Ithorians demonstrated Force-sensitivity.
The derogatory term "leathernecks" was applied to Ithorians by Imperial stormtroopers. The Ottegan species represented a genetic divergence from the Ithorians, exhibiting a comparable physiology, albeit with a single mouth instead of two.
The majority of Ithorians were characterized by their peaceful nature and reverence for the natural world. Their pacifistic principles were so deeply ingrained that they banished any individuals displaying violent tendencies from their home planet, Ithor. They held Ithor as sacred and strictly forbade hunting on the planet's surface. While Ithorians cultivated their forest gardens on Ithor, the majority of the planet's surface was enveloped by the Mother Jungle, a massive rainforest considered sacred by the Ithorians, who prohibited entry to anyone.
Ithorian society was structured into herds, which were essentially extended tribes connected by shared traditions and intermarriage.
Ithorian culture placed significant value on nature, leading to the meticulous creation of various spiritual artifacts. Ithorian totems, meticulously carved from stone, served as grave markers, holding profound spiritual significance on Ithor. Ithorian Weather Chimes were handcrafted and used in prayers for fertile soil and favorable weather conditions for gardening.
Driven by their reverence for the Mother Jungle, the Ithorians made a long-standing commitment to preserve the pristine condition of their homeworld, Ithor. To achieve this, they relocated their herds into enormous floating cities suspended in the skies above Ithor, eventually venturing out into the vast expanse of space.
Ithorians established a presence across the galaxy, inhabiting planets such as Coruscant and residing in at least one settlement on the planet Takobo, known as Hammertown. They could even be found in environments with minimal vegetation, such as Momaw Nadons hidden garden on Tatooine. While Ithorians were primarily recognized as peaceful horticulturists, many embraced diverse roles as they dispersed throughout the galaxy.
Several Ithorians made their home on the planet Tatooine. Momaw Nadon, an Ithorian male, was exiled from his homeworld for divulging his species' agricultural secrets to the Galactic Empire in an attempt to protect the planet. He later resided on Tatooine and frequented Chalmun's Spaceport Cantina in the city of Mos Eisley. Mok Shaiz, an Ithorian male, held the position of mayor in the city of Mos Espa on Tatooine during Boba Fett's takeover of Jabba's palace during the New Republic Era.
Dok-Ondar, a renowned Ithorian collector, operated Dok-Ondar's Den of Antiquities on the planet Batuu. At over 240 years of age, Ondar was the most notorious figure in Black Spire Outpost, curating a collection of rare and unique artifacts. Several Ithorians were members of the Jedi Order, including the Jedi Initiate Byph, Jedi Knight Mikkel Sutmani, and Jedi Roron Corobb.
While Ithorians were often stereotyped as peaceful gardeners and philosophers, individual Ithorians defied these generalizations. Bulduga and Onca were resourceful Ithorian bounty hunters, while Baron Boolan, who in his youth was a Little within the Path of the Open Hand cult, was an amoral scientist who became infamous and joined the Nihil at the invitation of Eye Marchion Ro himself, a descendant of Boolan's Path caretaker Marda Ro.
