Pocarto was a Galactic Empire sergeant, a human male, who worked as an instructor at the Empire's officers' academy located on the planet of Arkanis. He was a hatchet-faced, tall man.
This instructor was encountered by Zare Leonis while he was at Arkanis Academy, specifically during a field exercise where they utilized creatures referred to as diplopods. Pocarto offered some initial guidance regarding how to control these diplopods. After the exercise concluded, he voiced his satisfaction at seeing Leonis still living, especially considering that Leonis's diplopod, along with that of another cadet, Xan Lanier, had been killed. Pocarto was also there during a cadet assembly, where he complimented Leonis on how well his ceremonial uniform looked; however, later in the term, he showed irritation at Leonis's dirty boots. Ultimately, he attended a tribunal where Leonis was discharged from Imperial service for different offenses, including treason, and subsequently given a death sentence by firing squad.
