Troblom is a physicist, lacking in social skills and described by Marius as an idiot-savant when he as (for a short period) working with the Accelerator faction of the ANA. He is a history buff, fascinated by the Starflyer War, and pays extravagant amounts for war memorabilia. His social skills are so poor that he frequently consults software designed to help with social interactions, and, highly unusual for a society where people can alter their bodies such that almost everyone appears to be a physically fit and attractive persons in their twenties, is large, overweight, ungainly and unfit.
