Kisma Uttersond was a male physician of the Chadra-Fan species. Uttersond went to medical school at some point in his past, which resulted in him accumulating debt. He would eventually become a member of the Nihil pirate group, where he provided medical care to Mari San Tekka, a hyperspace prospector who was kept alive inside a medical capsule aboard the flagship known as the Gaze Electric. When San Tekka, who Marchion Ro of the Eye of the Nihil used to locate Paths through hyperspace, experienced seizures, Uttersond was called upon. Following the Great Hyperspace Disaster, Ro desired San Tekka to pinpoint the locations of future Emergences resulting from the event. Uttersond used his comlink to get in touch with Ro, arguing that San Tekka needed at least a week of rest. Ro disregarded the doctor's recommendation and ended the communication when he tried to continue the discussion.
Uttersond's family, including his spouse, Moonanoo, resided on the planet Chad.
Uttersond possessed both sadistic tendencies and great skill in the art of torture, yet he maintained that his role as a doctor involved helping individuals. Although he was capable of creating elaborate torture instruments, he never improved the prosthetic leg he used for mobility. Uttersond reluctantly worked for the Nihil in order to settle his medical school debts, harboring a dislike for both the Nihil and the Jedi. Despite his sadistic nature, Uttersond had a deep affection for his wife Moonanoo and their fanlings, for whom Beesar Tal-Apurna believed the doctor would do anything.
