Trench Trench was a Harch Admiral and naval commander who survived a number of presumed death s throughout his career . Hailing from Secundus Ando , he acquitted himself in engagements with the Galactic Republic , all the while savoring the terror he struck in his enemies . Years after his purported death at the Battle of Malastare Narrows , he resurfaced during the Clone Wars , becoming a key officer in the navy of the Confederacy of Independent Systems . From the dreadnought " Invincible " he oversaw the Confederate blockade of Christophsis , which brought him into conflict with a Republic battle group led by Jedi General s Obi - Wan Kenobi and Anakin Skywalker along with an old foe , Admiral Wullf Yularen . When Skywalker and Yularen attempted to use an experimental stealth ship to breach the blockade , Trench began a deadly game of cat and mouse with them . Though Skywalker outwitted him by redirecting a volley of proton torpedo es at the " Invincible " , Trench managed to survive his flagship ' s demise . During the Battle of Ringo Vinda , Trench captured clone trooper Tup — who had mysteriously gunned down Jedi General Tiplar — and tried to send the clone to Separatist leader Count Dooku for examination , though a Republic team intervened and rescued Tup . In another campaign , Trench besieged the Republic shipyards at Anaxes for weeks on end , exploiting the Techno Union ' s secret access to a Republic strategy algorithm . Even as the tide of battle began to turn , Trench remained intent on annihilating the Jedi and their clone infantry . Though he activated a bomb beneath the assembly complex on Anaxes , Skywalker infiltrated Trench ' s flagship and forced the admiral to divulge the sequence to disarm the device . When Trench tried to retaliate , Skywalker drove his lightsaber through his chest , inflicting a death that even the hardened Harch could not escape . Biography . Early life . Trench was a remarkably tough male Harch from Secundus Ando , Trench saw service in multiple battles throughout his military career , mostly in cruiser - to - cruiser action . In many of these battles he would fight against forces utilizing cloak ed starship s , defeating them through the use of tracking torpedo es fixed on the vessels ' magnetic signatures . Trench would eventually rise to command a corporate fleet that blockaded the planet Malastare . Trench was able to hold his lines against a Republic fleet led by Wullf Yularen sent to break the blockade , tearing their ships apart . However , a Jedi - led taskforce commanded by Master Kep - She was able to defeat Trench , vaporizing his flagship and seemingly killing him in the process . In reality , however , Trench survived the battle with the help of the Harch ' s hardy biology as well as a damaged pressure suit . Clone Wars . Reemergence . Trench , along with his tactical droid , TI - 99 , were then sent to Christophsis to assist General Loathsom and Count Dooku ' s assassin , Asajj Ventress in seizing the planet for the Confederacy , and blockading the planet to tighten their grip of the system . There , he commanded the blockade from his war - painted flagship , the " Invincible , " to prevent Senator Bail Organa of Alderaan and other republic relief forces from being resupplied and to cripple any attempts to penetrate the blockade . Trench then held his lines against Jedi General Anakin Skywalker ' s fleet . Trench then watched as the Republic fleet retreated by the moon and had his force recharge their cannon s . < nowiki > < / nowiki > While the Jedi retreated and regrouped , Trench felt that he had won the first round . His tactical droid was puzzled and asked Trench if they should pursue . The Admiral instead ordered his troops not to follow the enemy , as per the commands he was issued by higher authority ; after which , Trench commanded his droids to recycle the ship ' s shields and allow the cannons to recharge to full power . The Admiral , satisfied with the proceedings , seated himself at the bridge and awaited for the return of the enemy ships . However , Trench ' s old adversary from Malastare Narrows , Admiral Wullf Yularen , was also present with Skywalker at the battle . After recognizing Trench ' s trademark insignia painted on his flagship , Yularen studied everything Republic Intelligence had provided on the Admiral ' s tactics , allowing him to plan a counter - attack . This came in the form of an experimental stealth ship , piloted by Anakin Skywalker himself and Admiral Yularen as an adviser . Unaware of the existence and capabilities of the cloaked ship , Trench then grew impatient with the Republic fleet and to put pressure on the Republic fleet to attack , Trench sent a squadron of Hyena bombers to attack Organa ' s refugee camp , particularly the command center as a plan to draw out the Republic on the surface who Trench viewed as " cowards . " When the Republic fleet did not attack , Trench sensed that something odd was happening . Trench then spotted a cloaked ship moving to attack him . Trench and his crew were then able to raise the " Invincible ' s " thermal shield s . Trench fired torpedoes at the stealth ship , but missed . Trench then ordered a volley of laser s to be fired at it , and since no shots landed , Trench was able to deduce that the pilot was a Jedi , not a clone . Trench sent a message to Skywalker , telling him that he has dealt with cloaked ships before . He also gloated that Christophsis ' citizens and resources would join the Separatist Alliance . Trench also told Skywalker to retreat , for he was his doom . Trench prepared himself for the Jedi ' s inevitable second offensive . Eventually the cloaked vessel revealed itself , but this time , the crew had knowledge of Trench ' s tactics when dealing with ship cloaking devices . After Skywalker attacked , Trench was able to track the ships magnetic signature using tracking torpedo es so he could follow and destroy them . At first , Trench ' s tactic worked . However , he would forced to lower his shields to do so and the droid advised that such a maneuver would be unwise . In a moment of compulsive anger ( and against his droid ' s advice ) , Trench gave the order and the torpedoes were launched . He noticed that Skywalker was leading the torpedoes back to the " Invincible ' s " bridge . Trench tried to raise his shields , to no avail . Trench accepted his fate , but was able to survive once again . However , he lost his left eye and several of his appendages . Cyborg . Trench , alongside the super tactical droid Kraken , later commanded the Separatist forces on the space station at Ringo Vinda against Jedi Generals Tiplee , Tiplar , Skywalker , and their clone forces . As the Republic came close to breaking his lines , Trench witnessed one of the clone troopers kill General Tiplar . Trench ' s observation for minor details proved vital as it allowed Sidious and his apprentice , Count Dooku to create a cover - up before the Jedi Order could discover the existence of Protocol 66 prematurely . Trench described to Count Dooku his observations , telling him that the clone looked " like he was in a trance of some kind . " Trench then had Kraken capture and deliver the clone to Dooku , despite the Republic ' s blockade . After successfully kidnapping of the clone trooper " Tup , " the Count applauded the Harch ' s success , Trench then tasked Kraken to personally escort the captured Clone to Dooku himself . However , the mission failed as the Republic recaptured Tup and Kraken was decapitated by Anakin Skywalker . Following the recapture of Tup , the Republic eventually withdrew its forces from Ringo Vinda . Death . Later in the Clone Wars , Trench , now on the offensive , commanded the Confederate forces during the battle for the Republic ' s vital shipyards on Anaxes in a campaign which lasted for several months . Trench used his own tactical acumen , as well as using the Republic ’ s strategy algorithms against them using the Techno Union ' s test subject on Skako Minor , a captured ARC trooper named " Echo . " Trench was killed by Skywalker after Clone Force 99 and Echo boarded his ship as Trench primed a bomb planted on the planet surface . Echo was able to decipher all but the final sequence for the bomb , forcing Anakin Skywalker to ambush Trench and threaten his life for the final sequence for the detonation code . While Anakin was preoccupied giving Jedi General Mace Windu the final sequence , Trench took advantage of the Jedi ' s distraction by electrocuting him . This action prompted Anakin to retaliate , thrusting his lightsaber and delivering the final blow to the Harch Admiral . As Trench writhed in agony on the floor , Anakin acquired the self destruct detonator of the flagship and indifferently bid the admiral a final farewell as he departed . As Clone Force 99 escaped , they planted remote detonators along the corridors , and activated them after leaving the ship , vaporizing Trench ' s body along with several of his ships . Legacy . Although Trench ' s flagship , the " Invincible " , was destroyed by Anakin Skywalker in a cloaked stealth ship during the Battle of Christophsis , some of the flagship ' s modules were salvaged and used to modify a Separatist dreadnought owned by Berch Teller ' s rebel cell to attack the Empire ' s Sentinel Base in 14 BBY . Personality and traits . Trench was a fearsome Harch admiral who was far larger than the average member of his species , as the arachnids seldom grew to such size due their exoskeletons not being able to bear the weight of the fur . Trench became a terror on the battlefield , as he held no mercy or remorse toward his opponents . He was a well - decorated military genius and his aggressive tactics and maneuvers in combat made him responsible for the destruction of many Republic fleets . His skill in hunting cloaked ships through the use of tracking magnetic signatures was also noted and recorded in the Republic Intelligence record , which was studied during the blockade of Christophsis by Admiral Yularen . Trench prided himself for having won many victories in the war , resulting in him developing an overconfident personality and often boasting about outsmarting his opponents . Trench often viewed his battles like a game and would often cajole and taunt his enemies as he made his moves , before leading them into a vulnerable position where he could eliminate them . However , his overconfidence nearly led to his own demise at the hands of Anakin Skywalker when he made an uncharacteristic oversight which left himself vulnerable to incoming missiles . Even when his death appeared imminent , Trench did not panic or show distress ; he simply accepted his fate . Following his defeat , Trench was immediately fitted with " top - of - the - line " cybernetics making up half of his limbs and face to ensure his quick return to service . Trench , learning from his mistakes of lowering his guard , carried an electrostaff - cane variant as well as one of his cybernetic arms being equipped with an electronet which he used against Skywalker prior to his demise . Trench ' s Flagships . Trench ' s First Ship . Trench ' s first flagship was part of a corporate fleet which was present at the Battle of Malastare Narrows where Trench blockaded the planet and engaged Wullf Yularen ' s republic fleet which was successful until a Jedi - led task force intervened and sabotaged his campaign . It was believed that he had gone down with his ship , but this was later proven false at the Battle of Christophsis in 19 BBY . The " Invincible " . The " Invincible " served as the Harch commander ' s first command ship after his reemergence where it blockaded the planet of Christophsis , offering a great range of attacks and it was said that the cruiser could blockade a planet on its own . Unlike the stock variant of a Separatist dreadnought ; Trench ' s was well - equipped with heavy deflector and thermal shields which allowed for a powerful defense . However , Trench underestimated the opposing commander , Jedi Anakin Skywalker , resulting in him losing the upper hand and Anakin taking advantage of the Admiral ' s temper by redirecting Trench ' s projectiles to the bridge of his ship . Trench ' s Flagship ( Anaxes ) . Trench ' s Flagship ( Anaxes ) was commanded by Trench during the Battle of Anaxes where he relayed transmissions from Wat Tambor on Skako Minor to predict the Republic ' s forces on Anaxes and issuing commands before being infiltrated by the Republic and ultimately assassinated by Anakin on the bridge of his ship . Behind the scenes . Admiral Trench was created for the " " television series and made his first appearance in the second season of the series " Cat and Mouse " and voiced by Dee Bradley Baker also known for voicing the Clone trooper s in the series . Trench was confirmed to have survived in " Cat and Mouse " and make his return in the series in the episode " The Unknown " , where Trench is alive with half his body consisting of cybernetics . Additionally , " Clone Wars " writer Brent Friedman confirmed on his Twitter account that he wrote a four - part episode arc that wasn ' t published that featured Trench . The episode arc , was screened at Celebration Anaheim " Star Wars " convention as story reel form apart of " The Clone Wars Legacy " project in 2015 , which would have featured the return and death of Admiral Trench . The episodes were later released on StarWars . com .
