Kassius Konstantine Kassius Konstantine was a human male from Coruscant who served as an Admiral in the Imperial Navy . He was dispatched to the Lothal system where a rebel movement occurred . After the Spectres joined the rebellion , Admiral Konstantine would continue to hunt them down under the command of Agent Kallus and the Inquisitor known as the Fifth Brother . Despite their efforts and superior resources , the rebels proved elusive for Konstantine and his comrades . Admiral Konstantine ' s failed attempts to stamp out the rebellion led Governor Arihnda Pryce to solicit the services of Grand Admiral Thrawn , a seasoned tactician and the commander of the Seventh Fleet . In an effort to test the Admiral ' s talents and capabilities , Thrawn dispatched Konstantine on a mission to destroy the Iron Squadron , a rebel cell based at Mykapo . Konstantine managed to trap the Squadron ' s captain , Mart Mattin , but underestimated the ingenuity of the Spectres and Mart ' s uncle Commander Jun Sato . Konstantine was greatly embarrassed by this skirmish , and attempted to spin the incident in a positive way . However , Thrawn saw through his obfuscation . Some time later , Konstantine , commanding an Interdictor vessel , accompanied Thrawn and Pryce at the Battle of Atollon . Consumed by his arrogance and jealousy , Konstantine pursued the Quasar Fire - class cruiser - carrier " Phoenix Nest " , defying Thrawn ' s direct orders of holding back . This maneuver cost Konstantine his life as Commander Sato rammed the " Phoenix Home " into the Interdictor , destroying both cruisers . Biography . Empire Day . In the years before the Battle of Yavin , Kassius Konstantine commanded an Imperial fleet from his flagship , the Imperial Star Destroyer " Relentless " . He aided the Inquisitor in his search for the " Ghost " , a rebel starship . After the Spectres rescued another fugitive , the Rodian Imperial Information Office staffer Tseebo , and breached the Imperial security cordon around the planet Lothal ' s Capital City , Konstantine commanded the " Relentless " in the pursuit of the rebels . With Tseebo ' s help , the rebels escaped into hyperspace . While Konstantine thought of shifting the blame for the rebels ' escape to the Inquisitor , he declined since the Sith agent had succeeded in planting a tracking device onto the hull of the " Ghost " . When Admiral Konstantine reported that they were receiving a signal from the tracker , the Inquisitor did not acknowledge his presence but merely commented that he himself could sense the Jedi Kanan Jarrus and his Padawan Ezra Bridger . In response to the Inquisitor ' s comments , Konstantine stifled a laugh , as he believed that the Empire had wiped out the Jedi years ago during the Jedi Purge . He was personally skeptical of reports that the leader of that rebel cell was a Jedi . However , the Inquisitor read his emotions and scowled back at the Admiral . Fearing that his long and storied career would end if he failed to capture the rebels , he vowed that they would succeed . Meanwhile , the Spectres realized that there was a tracking device planted onto the " Ghost " auxiliary vessel , the " Phantom " . To prevent the Imperials from capturing Tseebo , Kanan and Ezra separated from the " Ghost " and flew the " Phantom " to the asteroid PM - 1203 , which hosted a former Republic base called Fort Anaxes . As planned , the Imperials took the bait . When Admiral Konstantine ordered that the " Relentless " land an entire battalion on that asteroid , the Inquisitor countermanded his orders and instead led a small contingent of stormtrooper s to the PM - 1203 . The Inquisitor ' s troops were quickly dispatched by fyrnock s , fearsome predators that resided in the asteroid . Despite the Inquisitor ' s lightsaber skills and Force powers , Kanan and Ezra managed to escape ; leaving both the Inquisitor and Admiral Konstantine empty - handed . Looking out for smugglers . Admiral Konstantine was at the helm of his Star Destroyer " Relentless " when one of his crew took an interest in a VCX - 100 light freighter approaching Lothal . This freighter turned out to be the rebel ship " Ghost " . However , the Spectres managed to fool the scanning technician and Konstantine by using a signature modulator to disguise the " Ghost " as the " Tontine " ; a legitimate vessel traveling between Boz Pity and Lothal . The " Ghost " was transporting the " galactic entrepreneur " Lando Calrissian , who was trying to smuggle a puffer pig onto Lothal for an illegal mining operation . The rebels almost made it through the blockade undetected until Ezra accidentally disturbed the puffer pig ; causing it to throw Garazeb Orrelios off balance onto the ship ' s control console . This effectively deactivated the signature modulator and exposed the " Ghost " to the Imperial authorities . Konstantine then dispatched four TIE / ln space superiority starfighter s after the " Ghost " , but the rebels managed to lose their Imperial pursuers in Lothal ' s cloudy skies . Serving Tarkin . After the Inquisitor captured the rebel Jedi Kanan Jarrus sometime later , Konstantine was temporarily reassigned to Grand Moff Wilhuff Tarkin ' s flagship , the " Sovereign " , while over the planet Mustafar . After a lightsaber duel between Jarrus and the Inquisitor destroyed the " Sovereign " , Konstantine took part in the blockade of Lothal intended to ensnare the Spectres . He was unsuccessful in this , however , as the rebels managed to evade capture again by deploying masking transponder s emitting false signals , allowing them to escape in their stolen " Sentinel " - class landing craft . Shortly afterwards , Konstantine and the " Relentless " were part of the surprise attack on the Phoenix Cell , led by Sith Lord Darth Vader , who was piloting a TIE Advanced x1 starfighter . As the " Ghost " made its escape , Konstantine activated his Destroyer ' s tractor beam to attempt to catch them , however , he instead ended up catching Vader as the rebels jumped to hyperspace . Knowing that his life was in danger for this mistake , Konstantine blamed his failure on a subordinate bridge officer . Mission to Seelos . After the Spectres had escaped from Darth Vader , Admiral Konstantine continued his command of the " Relentless " which was still hunting for the rebels . He was accompanied by the Imperial Security Bureau agent Kallus , who also had experience dealing with these rebels . Under instructions from the former Jedi Padawan Ahsoka Tano , the Lothalian rebels had traveled to the desert planet of Seelos to make contact with several retired Clone trooper s : Rex , Wolffe , and Gregor . The rebels hoped to win them over to their cause . Wolffe , distrusting the rebels , secretly sent a coded transmission that was picked up by the " Relentless " . Agent Kallus sent a probe droid to Seelos to investigate . Prior to its destruction , the droid succeeded in sabotaging the rebels ' shuttle the " Phantom " , and confirmed there was indeed a rebel presence there . While Agent Kallus led a ground assault with three AT - AT walkers , Admiral Konstantine remained aboard the " Relentless " to render air support to Kallus ' forces . However , the clones and rebels put up an unexpectedly fierce fight and succeeded in immobilizing Kallus ' AT - AT walkers . The Admiral was unable to render air support because Darth Vader had ordered him to rendezvous the " Relentless " with his shuttle in space . Instead of meeting Vader , Admiral Konstantine received another Inquisitor known as the Fifth Brother . When Konstantine raised his concerns that the diversion might have compromised Agent Kallus ' mission , the Inquisitor merely replied that his struggles were of no concern to him and pledged to stop the rebels himself . Serving the Inquisitors . Following the Imperial misadventure at Seelos , Admiral Konstantine continued serving under the Fifth Brother . He and Agent Kallus were later present aboard the bridge of the " Relentless " when his crew picked up a surge of energy at an abandoned medical station . This surge had been triggered by several members of the Spectres , a rebel cell that had harried Konstantine and his Imperial comrades several times . These rebels had been searching for medical supplies for Phoenix Squadron . In response to the surge , the Fifth Brother informed the Admiral and Kallus that he was visiting the station alone . There , the Fifth Brother and another Inquisitor known as the Seventh Sister almost succeeded in apprehending Chopper , Ezra Bridger , and Sabine Wren . However , due to Garazeb Orrelios ' quick thinking , the four rebels managed to escape the two Inquisitors . Later , Admiral Konstantine and the two Inquisitors were present when Agent Kallus suggested that the Imperials pool their resources together for a strike on Garel . Following an earlier incident on Takobo , the Inquisitors had learned that the rebels were hiding on Garel . Under Kallus ' orders , Konstantine and the Imperial fleet departed from Lothal and traveled to Garel . Despite surrounding the rebels on both the ground and air , several rebel ships , including the Spectres ' ship the " Ghost " and Commander Jun Sato ' s CR90 corvette , still managed to escape into the skies above Garel City . Commanding the air assault , Admiral Konstantine ordered the crew of his Star Destroyer to deploy their tractor beam projector . His forces also succeeded in shooting down at least one rebel ship . The " Relentless " tractor beam managed to trap Commander Sato ' s corvette . However , Phoenix Leader Hera Syndulla used the " Ghost " to ram the tractor beam projector ; knocking it out of action . The damaged projector collided with a TIE fighter . This distraction enabled the Phoenix rebel fleet to make a jump into hyperspace . When Agent Kallus , who had led the ground assault , demanded an update on the location of the rebel fleet , a visibly frustrated Admiral Konstantine reported that he and his men were also wondering the same thing . Despite exposing one of the Phoenix rebels ' hideouts , Konstantine and his Imperial colleagues failed to crush the rebel cell . Hunting the Rebels . Admiral Konstantine and Agent Kallus later commanded an " Arquitens " - class command cruiser which attempted to capture the rebel ship the " Ghost " above Nixus . Despite their efforts , the " Ghost " managed to jump into hyperspace . Earlier , the crew of the " Ghost " had rescued two Lasat refugee s named Gron and Chava , who were searching for the legendary Lasat homeworld of Lira San . With the help of the Weequay pirate Hondo Ohnaka , the Imperials managed to track the " Ghost " down to a collapsed star cluster in Wild Space . The Imperials attempted to pursue and destroy the " Ghost " but were forced to retreat due to the gravitational pull of the star cluster . Later , Konstantine encountered Kallus in the corridor of a Star Destroyer after the latter had returned from a failed attempt to ambush the Spectres onboard an Imperial construction module above Geonosis . On the way to his quarters , after narrowly surviving the freezing temperatures of the ice moon Bahryn , Kallus greeted Konstantine , who responded with a nonchalant acknowledgment devoid of emotion . Konstantine ' s coldness contrasted with the warmth and unlikely friendship that his rebel opponent Garazeb Orrelios had shown him on Bahryn . Admiral Konstantine later commanded an Imperial assault on Phoenix Squadron from his Star Destroyer " Relentless " . When one of his subordinates reported that the " Ghost " was exiting hyperspace with stolen fuel supplies from Horizon Base , Konstantine ordered his TIE fighters not to let the ship dock with the rebel flagship , a former Imperial " Quasar Fire " - class cruiser - carrier that had been stolen on Ryloth . Despite their best efforts , Konstantine ' s TIE fighters were chased away by Ketsu Onyo ' s starship " Shadow Caster " . Later , the rebel fleet escaped to Atollon with the help of the former Imperial inventory droid AP - 5 , who informed the rebels of an Imperial trap in the Yost system . Under Pryce ' s command . Dissatisfied with Admiral Konstantine ' s handling of the rebel insurgency in the Lothal sector , Governor Arihnda Pryce met with Grand Moff Wilhuff Tarkin and secured the services of the newly - appointed Grand Admiral Thrawn and his Seventh Fleet . Later , Konstantine met with Grand Moff Tarkin and Agent Kallus at the bridge of a Star Destroyer . Konstantine told Tarkin that Pryce was overestimating the threat posed by the Phoenix rebels and dismissed them as a localized insurgency . At that point , Thrawn interjected and expressed his hopes that the insurgency would remain that way . Konstantine was present when Thrawn theorized that the Phoenix rebels were planning to raid Reklam Station in the planet Yarma . Later , Konstantine , Pryce , and Kallus commanded a Star Destroyer that intercepted the rebels and their stolen Y - wing starfighters . He expressed surprise when Thrawn ordered the Imperials to allow the Phoenix rebels to escape with their " meager reward . " However , Pryce reassured him that Thrawn had a much larger objective than the destruction of a single rebel cell . Later , Admiral Konstantine was aboard the bridge of an Imperial Star Destroyer with Governor Pryce and Agent Kallus . He informed Pryce that his crew had detected an encrypted distress signal from the planet Agamar . Pryce then dispatched Imperial forces from the nearest garrison to investigate Agamar ; bringing them into conflict with members of the Phoenix Squadron and a Separatist holdout led by the super tactical droid Kalani . Test above Mykapo . Under orders from Grand Admiral Thrawn , Admiral Konstantine reluctantly departed for Mykapo with a single light cruiser and two " Gozanti " - class cruisers . Thrawn had tasked the Admiral with eliminating a local rebel cell called the Iron Squadron . When Konstantine offered to send his squadron , Thrawn replied that a man of his talents should have no difficulty eliminating the rebel cell with one light cruiser . By the time Konstantine had arrived , Phoenix Group had already evacuated the rebel sympathizers among the population . Upon arriving , Konstantine ' s subordinate sighted a single YT - 2400 light freighter . The Admiral believed that Thrawn had overestimated the threat posed by the rebel cell and dispatched fighters to attack the ship . The ship ' s captain , Mart Mattin , launched an attack on Konstantine ' s light cruiser , underestimating the Admiral . Meanwhile , his fellow crew and the Spectres Ezra Bridger , Sabine Wren , and Chopper escaped aboard the shuttle " Phantom II " . Mart released his cargo of explosives , but Konstantine neutralized them by unleashing his ship ' s forward batteries . Mart attempted to flee , but Konstantine ' s TIE fighters disabled his engines . However , Konstantine ' s forces were unable to stop the other rebels from escaping into hyperspace aboard the " Phantom II " . One of Konstantine ' s TIE bombers attached a magno - mine to the hull of " Sato ' s Hammer " . Konstantine then allowed Mart to send a distress signal to the Spectres before jamming it , intending to lure Mart ' s rescuers into a trap . However , the Spectres saw through his trap and devised a counter - strategy . When the Spectres returned aboard the " Ghost " , Konstantine ordered his subordinate not to trigger the mine until he gave orders . He wanted to destroy the two rebel ships in one fell swoop . However , the rebel astromech droid s Chopper and R3 - A3 detached the magno - mine and planted it on one of the " Sato ' s Hammer " cargo boxes . When the " Ghost " undertook a pick - up of Mart ' s ship , Admiral Konstantine ordered his subordinate to trigger the mine . Konstantine ' s plan was complicated by the arrival of Mart ' s uncle Commander Jun Sato aboard a CR90 corvette . Sato ' s reinforcements destroyed one of Konstantine ' s " Gozanti " cruisers and several TIEs . Konstantine panicked and called Thrawn for help . The " Ghost " then flew over Konstantine ' s light cruiser while ferrying Mart ' s ship . Mart then dislodged the cargo box at the same moment that Konstantine ' s officer triggered the mine . The resulting explosion destroyed the forward compartment of Konstantine ' s light cruiser . Konstantine and the officer survived the blast but their ship was badly damaged . At that point , Thrawn arrived in the system . Thrawn allowed the rebels to escape following a brief exchange with Commander Sato . Thrawn then contacted Konstantine via hologram . When Thrawn asked him whether he had contacted him for assistance , Konstantine tried to save face by claiming that he had called to inform him that the rebels had been driven from system . However , Thrawn saw through Konstantine ' s obfuscation and replied that he had assumed that the rebels and not their sympathizers had escaped . Konstantine bowed his head in embarrassment . The hunt for Fulcrum . During Thrawn ' s investigation into the rebel spy known as Fulcrum , Admiral Konstantine was stationed aboard the Grand Admiral ' s Imperial Star Destroyer " Chimaera " . He introduced Agent Kallus and Lieutenant Yogar Lyste to Thrawn and the Imperial Security Bureau Colonel Wullf Yularen . Konstantine was present at a meeting where Thrawn briefed the others about Fulcrum , a traitor in the ranks who had been aiding Phoenix Squadron as a spy , who Thrawn attributed the recent Imperial defeats and Rebel successes to , and explained his plan to screen the Lothal Sector ' s Command staff for Rebel affiliations . Konstantine was also privy to Thrawn ' s plan to hunt down Phoenix Squadron ' s base in the Lothal sector . When he asked about Thrawn ' s tactics , the Grand Admiral replied that he had calculated the possible locations of the rebel bases based on their proximity to attacks on Imperial ships and facilities , and the planet Lothal . After Kallus had apprehended Lyste , accusing him of being the Rebel spy , Konstantine was present at a meeting with Governor Pryce , Colonel Yularen , Thrawn and Kallus . There , he congratulated Kallus for catching the spy . After Konstantine , Kallus and Pryce left , Thrawn revealed his knowledge of Kallus being the real spy to Yularen . The Hunt for Mon Mothma . Later , Admiral Konstantine attended a briefing with Governor Pryce and Grand Admiral Thrawn to discuss plans to capture the fugitive former Senator Mon Mothma , who had incurred the wrath of the Emperor for denouncing the Ghorman Massacre and calling the Emperor a " lying executioner " . At the briefing , both Konstantine and Pryce expressed disbelief when Thrawn theorized that Phoenix Leader Hera Syndulla would use the dangerous Archeon pass to smuggle Mothma out of the sector . When Pryce volunteered for the " honor " of silencing the rogue Senator , Thrawn tasked both Konstantine and Pryce with intercepting the rebel ships outside the Archeon Nebula . Thrawn ' s plan was to use his prototype TIE Defender and two TIE Interceptors to flush the rebels out of the nebula so that they could be captured by Konstantine and Pryce . For that mission , Konstantine and Pryce commanded two Imperial Star Destroyers . When the rebel ship " Ghost " exited the Archeon Nebula , Konstantine informed Pryce that the rebel ship had sustained damaged to its core systems . After Pryce rejected Mon Mothma ' s demands , she ordered Konstantine to activate the ship ' s tractor beam projector . When the surviving rebel Y - wings piloted by Ezra and Gold Leader Jon Vander exited the nebula , Konstantine ordered his gunners to shoot down the rebel fighters . Despite believing the rebel fighters had arrived " too little , too late " , Hera outmaneuvered the Imperials by convincing Ezra and Vander to fire their proton torpedo es into the Archeon Nebula . This caused the nebula ' s gases to ignite , badly damaging Konstantine and Pryce ' s Star Destroyers in the inferno . With the tractor beam disabled , the rebel ships fled to Dantooine . The Battle of Atollon . When Thrawn discovered the location of Phoenix Squadron ' s base on Atollon , he commanded Admiral Konstantine to deploy the Seventh Fleet to the system . Placed in command of an Interdictor vessel , Konstantine prevented the rebels from escaping the system . When Commander Sato attempted a Danan tactic , Thrawn ordered Konstantine to hold back until ordered otherwise . Dismayed , Konstantine protested and expressed his desire to use overwhelming force instead . Thrawn reminded Konstantine that he had studied the rebels and was familiar with their propensity to use unconventional tactics . When Commander Sato flew his Quasar Fire - class cruiser - carrier " Phoenix Nest " towards the center of the Imperial formation , Konstantine attempted to intercept the carrier . Thrawn ordered him to return to his assigned coordinates but Konstantine , desiring personal glory , expressed his tiredness with Thrawn ' s " games " . Sato ' s ploy proved to be a trap as he intended to draw the interdictor out of position and then surprise the admiral with a suicide run . Realizing his mistake too late , Konstantine frantically ordered evasive action , but could not prevent the destruction of his ship . Konstantine not only perished for his reckless insubordination , but his actions undermined the outcome of Thrawn ' s battle plans by allowing Ezra and Chopper to escape into hyperspace to seek reinforcements for the rebels . Personality and traits . Admiral Konstantine was a stern , by - the - books military leader . While he had a commanding presence , he always appeared perturbed by Force - users such as the Inquisitor or Darth Vader , and expressed his dislike for working with " mystics " . He showed little regard for any of his fellow Imperials , and on occasion he showed himself to be self - serving and was not above sacrificing his own men to save himself . Due to his long and storied career in the Imperial Navy , Admiral Konstantine felt that he had to excuse or somehow find someone else to pin his failings upon . Furthermore , he did not view his colleagues as friends , even Agent Kallus . He was also initially skeptical that any Jedi had survived the Jedi Purge . As his failures began to outnumber his victories , he grew increasingly eager to cover himself in personal glory , which would eventually become his fatal flaw . Konstantine was described as more of a politician than a soldier by Governor Arihnda Pryce , and was not highly regarded by the governor . Konstantine underestimated the threat posed by the rebellion and regarded them as a localized insurgency rather than a galaxy - wide insurrection . He lacked Grand Admiral Thrawn ' s strategic vision for defeating the entire galactic rebellion . Konstantine appeared to favor overwhelming military force and felt insufficient in handling the Iron Squadron with just one ship . He also underestimated the ingenuity and resourcefulness of his numerically and militarily inferior opponents . Konstantine was familiar with the rebel habit of returning to rescue their stranded comrades . Anticipating this , he did not destroy Mart Mattin ' s ship but instead planted a magno - mine on it . He intended to lure Mart ' s rescuers into a trap and destroy both rebel ships . However , the Spectres saw through his plan and neutralized it by getting the astromech droids Chopper and R3 to disable his magno - mine . Konstantine also panicked when confronted by unexpected enemy forces and sought assistance from Thrawn . When Thrawn confronted him over his failure , Konstantine tried to hide the truth by claiming that he had driven the rebels away . However , Thrawn realized that Konstantine was obfuscating and corrected him . Konstantine expressed disbelief when Grand Admiral Thrawn predicted that the rebel Hera Syndulla would be risky enough to ferry Senator Mon Mothma through the dangerous Archeon pass . He and Pryce followed Thrawn ' s plan to trap the rebels . Konstantine believed that victory was imminent since Commander Skerris had wiped out most of the " Ghost " Y - wing escorts and that the rebel ships were outgunned and outnumbered by his Star Destroyers . However , Hera turned the tables on Konstantine and Pryce by convincing her Y - wing pilots to fire their proton torpedoes into the nebula , damaging the Star Destroyers . As his bitter jealousy towards Thrawn grew stronger , he became insubordinate and willing to defy the Grand Admiral ' s command in battle . During the Battle of Atollon , Konstantine defied Grand Admiral Thrawn ' s orders and tried to intercept the Rebel command ship " Phoenix Nest " with his own interdictor cruiser . However , Commander Sato , the captain aboard the rebel ship , changed course last minute and rammed Konstantine ' s cruiser , destroying both himself and the interdictor but allowing Ezra and Chopper ' s ship to escape the blockade . Behind the scenes . Kassius Konstantine is a " Star Wars Rebels " character who first appeared in the first season episode " Gathering Forces " . He is voiced by " " veteran Dee Bradley Baker . Konstantine was given some point - of - view passages in Michael Kogge ' s chapter book " Ezra ' s Duel with Danger " , which was based on the " Star Wars Rebels " episodes " Empire Day " , " Gathering Forces " and " Path of the Jedi " . These passages shed light on his personality and tense relationship with the Inquisitor . Konstantine was killed off in the third season finale " Zero Hour " , which premiered on March 25 , 2017 .
