TK-8190 identified a male stormtrooper of the human species who operated under the service of the Galactic Empire while stationed on Bracca.
TK-8190 held a position within the Stormtrooper Corps of the Galactic Empire. His assignment in 14 BBY placed him on Bracca. Following Cal Kestis, a Jedi Padawan who lived through Order 66, managing to evade capture by the Inquisitors known as the Second Sister and Ninth Sister, Kestis plummeted through the ceiling of a moving train where TK-8190 was working. TK-8190, along with another trooper, went to investigate the noise, discovering Kestis recovering. As the Jedi was attempting to reason with the stormtroopers, TK-8190 incorrectly assumed him to be a stowaway, prompting Kestis to beg the two soldiers to not report what happened. The temporary peace ended, however, when TK-8190 made the choice to report Kestis' presence and was informed that the stowaway was in reality a Jedi. This resulted in TK-8190 and his fellow trooper being quickly killed by Kestis using his lightsaber in an act of self-defense.
