Bonic Tarracus Bonic Tarracus , codenamed Corewatch , was an extremely reliable agent throughout the Galactic Civil War . An agent for the Rebel Alliance , Tarracus was stationed amongst the Core Worlds for most of the war . Around 0 BBY false information planted by the Galactic Empire resulted in Tarracus leading a group of Rebel agents to their deaths took a tremendous toll on his psyche and subsequent information provided by him has been inaccurate due his poor mental health . After the Battle of Yavin he retreated back to his homeworld , Coruscant . Biography . Bonic Tarracus was born on the planet Coruscant sometime before the rise of the Galactic Empire and the New Order . He vowed to do whatever he could to destroy the Empire ' s grip on the galaxy . He assumed the code name of Corewatch and used his considerable disguise skills to impersonate Imperial officers around the Core Worlds to gather vital intelligence for the Rebel Alliance . Due to the sensitive nature of his mission few members of the Rebel Alliance even knew that ' Corewatch ' existed and fewer , if any , knew his true identity . The Empire became aware that covert information was being leaked and COMPNOR planted false information in order to identify the spy . In 0 BBY Tarracus reported on one such false piece of information regarding an Imperial munitions dump . A Rebel strike team composed of several top commandos of the 177th Light Infantry Division was inserted into hostile territory to blow up the target and Tarracus joined the team , posing as a commando . The resulting ambush captured and killed everyone else on the 20 - man squad . Tarracus barely escaped the ambush and began relocating between Core worlds at a quicker pace . Meanwhile the Imperial officer that Tarracus had impersonated was captured by COMPNOR who believed him to be the Rebel spy . Meanwhile Alliance Intelligence believed that the agent ' Corewatch ' had been captured as Tarracus broke contact with the agent ' s control officer . By 0 ABY Tarracus had resumed his clandestine work and reported accurately about a convoy of military supplies headed to a new covert COMPNOR installation on Belshar Othacuu . Alliance Intelligence was cautious that this could be an Imperial trap and sent only a small investigative team but they confirmed that Corewatch ' s intel was valid . Since then due to Tarracus ' poor mental state five of fifteen pieces of data provided by him have been spurious and often dangerously inaccurate . Again Alliance Intelligence believed that ' Corewatch ' had been turned into a double agent and the Empire was feeding " good " information to Corewatch in order to set up Alliance Intelligence for traps and ambushes . When it was discovered that Corewatch was set up on Coruscant , General Airen Cracken urged the Alliance to make an effort to capture or , if necessary , kill the potentially turned agent . Personality and traits . Tarracus was a nondescript Human male of average height , weight , and build . He had short light brown hair and kept himself well - groomed . Tarracus harbored severe feelings towards the Empire after witnessing the decline and fall of the Galactic Republic first hand on Coruscant . Originally a smooth operator , the disaster involving the 177th and his own near - death experience took a severe toll on his mental state . He became increasingly paranoid and moved between Core worlds at a frantic pace . His poor mental state also took a toll on the quality of information that he delivered and he went from being completely reliable to careless in a matter of months due to the event . He favored no typical habit for style or speech as he felt that any reoccurring habits could be recognized and prove ultimately fatal . Skills and abilities . Tarracus was a highly skilled impersonator who used his abilities of disguise and mimicry to infiltrate the Empire . He was able to impersonate high ranking officers at very public situations , like dress balls and other functionaries , without anyone suspecting anything . He was then able to simply ask other Imperials about " his current project " to gather all the intelligence he needed . He was so skilled that when COMPNOR planted false information as part of a spy hunt , the officer he impersonated was arrested for being a spy instead of anyone suspecting a mimic . He was a quick study and was very fast and accurate with his mimicry being able to blend into a wide variety of social situations . He could also speak a variety of languages , dialects , and accents . Tarracus was also highly skilled with blasters and had the skills to credibly impersonate a Rebel commando . He would often disguise himself as part of a tactical team to follow up on his own intelligence in order to ensure that everything went smooth . Behind the scenes . Bonic Tarracus was designed by Eric S . Trautmann for " Cracken ' s Rebel Operatives " , a supplement for the " " that was published by West End Games in 1994 .
