Tyrok, a Trandoshan male, existed during the era of the Galactic Civil War. Following the Battle of Yavin, he took on the role of personal bodyguard for Lady Valarian, a significant crime lord operating on Tatooine. In the year 1 ABY, Jabba Desilijic Tiure, Valarian's longtime adversary, contracted a spacer to assassinate Tyrok, aiming to disrupt Valarian's criminal operations. Subsequently, the spacer encountered Tyrok in the Dune Sea and carried out the assassination.
Tyrok was featured as a non-player character within the video game Star Wars Galaxies from 2003, a massively multiplayer online roleplaying game. This game was developed by Sony Online Entertainment and published by LucasArts, before it was shut down on December 15, 2011. Tyrok's inclusion in the game occurred with the revised "Jabba's Theme Park," which was launched alongside "Publish 25", also known as the "New Game Enhancements," on November 15, 2005. One particular mission originating from Jabba involved tasking the player with eliminating Tyrok.
