Walex Blissex Walex Blissex was a doctor and engineer of starship design , and later a general of the Alliance to Restore the Republic , esteemed and respected throughout the galaxy . His designs ranged from mammoth warships to minuscule starfighters , and his clients ranged from pan - galactic governments to insurrectionist rebellion movements . Working for such shipyards as Kuat Systems Engineering and Rendili StarDrive , Blissex created mainstays of the Grand Army of the Republic , such as the Delta - 7 " Aethersprite " - class light interceptor , and the " Victory " - class Star Destroyer . Blissex himself was not at ease with creating craft that could and would be used as killing machines , but he consoled himself with the fact that they were being used to police the galaxy and keep others from harm . Unable to use a computer properly , Blissex relied on assistants and his daughter , Lira . When Supreme Chancellor Palpatine made his grab for unlimited power in 19 BBY , Blissex rejected his New Order and quietly became a founding member of the Alliance to Restore the Republic . Lira , however , had other ideas , and essentially took her father ' s role in the Galactic Empire . Despite this , she was not as talented as her father , and when the Galactic Civil War broke out twenty years later , the domestic dispute between Blissex and Lira became intertwined with galactic affairs . The two would tangle throughout the war , with Lira consistently trying to trap or murder her father . Blissex overcame all obstacles however , and was able to serve the Alliance faithfully until it became the New Republic . In his later years , Blissex would see less active duty , but would serve with Jan Dodonna ' s " Gray Cadre " and eventually design the " Republic " - class Star Destroyer . Biography . Galactic Republic . The Clone Wars . Walex Blissex was a starship engineer who designed all kinds of craft , from starfighters to battleships . At some stage in his career , he earned the title of doctor . One of his personal friends Shil Tervo , who he occasionally collaborated with . Due to his inability to operate a computer , Blissex was always aided by assistants and his daughter , Lira . In 22 BBY , Blissex was working at Kuat Drive Yards , with the title of Project Engineer . Inspired by the " Aurek " - class tactical strikefighters from the Old Republic , he designed and developed the Delta - 7 " Aethersprite " - class light interceptor , a small craft purpose - built for use by the Jedi Order . Blissex was proud of his craft , and joined in the unveiling on Kuat with Senator Risi Lenoan and Jedi Knights Adi Gallia and Aayla Secura . Blissex took this opportunity to speak to HoloNet News . Blissex would adopt a number of Jedi modifications when designing the Delta - 7B " Aethersprite " - class light interceptor , which added a standard astromech droid port forward of the cockpit . Blissex ' s next design was the Eta - 2 " Actis " - class interceptor , a bold new direction in starcraft design . That new design was a fast , agile craft intended to be an extension of a Jedi pilot ' s abilities and reliant on their Force - enhanced senses . Lacking shields , and with its armor , sensors , and systems stripped down , the Eta - 2 allowed its Jedi pilots to fly almost as fast as they could think . In the waning days of the Galactic Republic and the Clone Wars , Blissex , with the help of Bevel Lemelisk , designed the " Victory " - class Star Destroyer for Rendili StarDrive . The craft was considered to be among the best of its kind , and although it saw limited use by the Republic , it would be a mainstay of the Galactic Empire fleet in the future . Although the " Victory " - class Cruisers were originally designed to operate NTB - 630 Naval Bombers alongside short - range A - 6 Interceptor s , their capacity was largely given over to snubfighter s by the end , and Blissex worked on developing a new generation of X - wing and Y - wing starfighters designed to dogfight on equal terms with any starfighters in space . Around the same time of designing the " Victory " - class Destroyers , Blissex also created the initial design for the " Gladiator " - class Star Destroyer , envisioning it as an escort for the " Victory " - class . Blissex himself was never comfortable with devising war machines , but he acknowledged the need for them to keep the peace . During this time , Blissex was called upon the Kuat Systems Engineering once more to develop the Alpha - 3 " Nimbus " - class V - wing starfighter , as a replacement for the V - 19 Torrent . Blissex saw this as an opportunity to correct flaws he perceived in the Delta - 7 . Defection and heartbreak . When Supreme Chancellor Palpatine made his grab for power in 19 BBY , Blissex chose to disappear from the galactic spotlight . He was idealistic , and he vehemently disagreed with Palpatine ' s policy of using weapons of mass destruction to police his new Galactic Empire , but he understood the threat that the Emperor posed to his safety . Rather than be forced to do that which he believed wrong , Blissex became one of the founding members of the Alliance to Restore the Republic . Despite this , his daughter married Imperial Governor Denn Wessex of the Relgim sector and took her father ' s intended place in the Empire . She designed the " Imperial I " - class Star Destroyer , working from her father ' s designs for the " Victory I " - class . The Rebel Alliance . The A - wing . Following the Battle of Yavin , General Jan Dodonna realized that the Alliance needed a starfighter that could match the TIE Fighter for speed and maneuverability . He approached Blissex , and together they developed the RZ - 1 A - wing interceptor . Blissex once more used the design of the Old Republic ' s Aurek strikefighters as the inspiration . Though Mon Mothma was initially skeptical , she gave in to the now - popular Dodonna , and the craft was developed . For research , Blissex and Dodonna examined the sleek ships of the Tammuz - an space navy , such as the R - 22 Spearhead . Mothma , however , refused to adequately fund the project , forcing Blissex to get the maximum output for the lowest amount of input . Putting his skills to good use , Blissex was able to successfully assemble the RZ - 1 , using components so common that they could be found anywhere in the galaxy , without sacrificing any performance whatsoever . Due to his service to the Alliance , he was given the honorary rank of general . Reunion on the " Subjugator " . Blissex served the Alliance faithfully as an engineering advisor , but the inconsolable rift between him and his daughter affected him greatly . Although he intended to amend their relationship , Lira did not . Eventually , Blissex learned from Denn Wessex that his daughter was apparently dying . Wessex pleaded with Blissex to make the trip to the Relgim sector to see Lira , but Alliance High Command was skeptical . Labeling it a trap , they cautioned Blissex against making the journey , but the esteemed engineer insisted that he was of no use to the Empire and that he would make the trip no matter what . Alliance High Command was still not satisfied , and so General Crix Madine dispatched two of his agents , Rexellian Marshall and Kan Deans to watch over Blissex . Wessex arranged to have Blissex picked up from Kwenn Space Station by the " Victory " - class Star Destroyer " Subjugator " , which would be traveling under the ruse of a supply stop . Upon reaching Kwenn , Blissex , Marshall and Deans were all thrown in the " Subjugator " detention cells , ready for interrogation by the fit and well Lira Wessex . Lira had devised the trap , as her designs for the " Imperial - I " - class had never been able to match the quality they would have reached at her father ' s hands . During the interrogation , the " Subjugator " fell under attack from Task Force Starfall , who was unaware that Blissex was aboard . During the battle , the Star Destroyer and the Rebel command ship took heavy damage , but the " Subjugator " was crippled , causing Captain Kolaff to set the " Subjugator " to self - destruct just as the Rebels would make their second attack , using a code known only to Lira and Blissex . During a power blackout , Marshall and Deans liberated Blissex from an interrogation droid . Due to the rigorous interrogation , the aging Blissex was exhausted and barely able to stand . The trio then made their way through the burning body of the " Subjugator " while being antagonized by Kolaff . Blissex ' s knowledge of his own ship design was critical in guiding the small group through the ship , but his comrades soon discovered that he did not know how to operate a computer . Deans , however , was able to discover Kolaff ' s plan to destroy the ship . Blissex realized he could turn the tables on Kolaff by setting the ship to self - destruct an hour earlier than scheduled . Making their way to the ship ' s core , Blissex , Marshall , and Deans battled various Imperial troopers along the way . Upon reaching the core , Blissex noticed that the self - destruct sequence was one known only to him and one other person : his daughter . The truth of the situation dawned on Blissex , and he realized that his own daughter had trapped him . The engineer was devastated at the news , but was given little time to console himself . The gambit to alter the self destruct sequence proved to be another trap , and the trio found themselves battling stormtroopers once again . Learning of a unoccupied shuttle in a far - off landing bay , the group set off throughout the harried ship , with Blissex guiding his two allies every step of the way . Eventually , the group encountered T - 3PO , a protocol droid capable of communicating with the ship ' s defense mechanisms . Seeing that the droid would come in useful , the Rebels decided to allow it to tag along . Traversing through areas of the ship so damaged that the artificial gravity had lapsed , the group eventually found their way to the docking bays , only to be confronted by Kolaff in an AT - ST . Marshall and Deans were able to procure their own AT - ST and defeated Kolaff in a brief confrontation , and the Rebels then moved on to Hangar Bay G - 12 . However , Lira and a squad of stormtroopers arrived to stop Blissex and his allies from escaping . As the assailants attempted to kill the Rebels , the droid complement of the " Subjugator " , abandoned by their masters , attacked Lira and the stormtroopers , buying Blissex time to escape . The members of Task Force Starfall picked up the trio , and Lira too was able to depart before the " Subjugator " exploded . Despite this , Blissex assumed that Lira had died in the explosion , leaving him no opportunity to reconcile their relationship . Heartbroken , Blissex returned to active service . Wayward experiments . Sometime later , Blissex received a holographic message from his friend , Doctor Issan Len . Len had developed the X0 - X1 , a droid that could control multi - faceted systems by itself . The doctor called Blissex in to inspect the new droid , but he also requested that Blissex arrange Alliance protection for the machine , as it would be deadly in the Empire ' s hands . However , by the time Blissex arrived at Cloud City , it was too late . He and his escort were delayed by some hostile droids , but as they reached Dr . Len ' s office , they discovered that he had been recently murdered and the X0 - X1 prototype had been stolen . Investigating the crime scene , the Rebels deduced that Len had been murdered by F - 3PO , a protocol droid from Bioniip Laboratories . The droid , however , had no recollection of the incident , and only spoke of " black tentacles " reaching out towards him . Before Blissex and his guards could act on the information , Baron Administrator Lando Calrissian arrived on the scene with a detachment of his guards . He insisted that the Rebels solve the crime or be arrested as suspects in Len ' s death . Following their only lead , the Rebels traveled to Bioniip Laboratories . Taking F - 3PO with them , the Rebels were informed by the Bioniip receptionist that the protocol droid had been sold to none other than Lira Wessex . Instead of expressing surprise at the discovery , Blissex was only disappointed , and to think that his daughter might have been involved in Len ' s death affected him greatly . F - 3PO , at first struggling to remember Lira , suddenly piped up and mentioned that his master was going to meet one Doctor Vreen at the Royal Casino . Hastily traveling to the Casino , the Rebels met a disguised Calrissian at a sabacc table . Calrissian had seen someone matching Lira ' s description , but he requested that one of the Rebels play a game of sabacc with him . As the game started , the group was approached by Helm Iskraker , who was also there to meet Vreen . During the game , they learned from Iskraker that he had stolen seven key cards from SecuriCo in the Indellum system , though when probed for the identity of his client , the alien feigned ignorance . He also had no knowledge of Lira whatsoever . Lira herself eventually showed up and sat down at the sabacc table with Iskraker , Blissex , the Rebels , and the disguised Calrissian . After some verbal sparring between Blissex and his daughter , Lira inquired as to Vreen ' s whereabouts , but no one had any answers . Lira was also puzzled by the accusation that F - 3PO was her droid , as she had never owned a protocol droid in her life . As the sabacc game progressed , the cards evolved into dark , flat , hemispherical shapes with tentacles coming out of them . The evolved cards matched the description recalled by F - 3PO at Len ' s lab . At that moment , a large labor droid entered the casino and moved to attack the patrons . After Blissex ' s Rebel escorts defeated the droid , however , they discovered that Lira , Iskraker , and Calrissian had all left . With information extracted from the wayward labor droid , the Rebels learned that it had come from Bioniip , which was apparently where Vreen was located . Blackout . Returning to Bioniip Labs , the Rebels were met with heavy resistance from a variety of droids . Left with no alternative , they blasted their way into the facility . They were confronted by odd humanoid droids and eventually discovered that the Bioniip cafeteria was been used as a makeshift prison . The Bioniip staff were being held there by the droids , who had apparently taken over the labs . They informed Blissex and his escorts that Vreen was alive and had hand - picked several scientists at gunpoint several hours prior . Venturing further into the facility , the Rebels came across a group of scientist ' s bodies that had been somehow made half machine . One of the bodies , situated on a lab table , was that of the still - alive Dr . Vreen . As the half - mechanical Vreen awoke , Blissex and his allies confronted him . They learned that he had taken X0 - X1 somewhere , but the exact location was lost to him . What he did know was that the location was sealed with seven locks , and that these locks could only be opened with the help of a " gold - skinned alien " and a " black haired woman . " Though the Rebels realized that the alien was Iskraker , they had no clues as to the identity of the woman . Vreen had been tortured by X0 - X1 and was forced to create Evolution Droid s — microscopic units that could transform flesh into metal . The scientists he had experimented on were dead , so he had been forced to use himself as a test subject . The only other things Vreen could remember were that some droids had taken a canister of Evolution Droids out of the lab , and that X0 - X1 was somehow controlling all the droids . Pressing Vreen further , the Rebels learned that the black haired woman was Bellum the Forger . They also discovered that X0 - X1 planned to take over Cloud City entirely . As the group discussed the situation with Vreen , X0 - X1 sent in a mouse droid carrying the evolution virus , hoping to infect Blissex and his companions . The plot was foiled however , and Blissex realized that the virus could be reversed to effect droids . Working quickly with Vreen , he developed a batch that would effectively serve as a poison to X0 - X1 . Before the Rebels were given a chance to depart Bioniip Laboratories , Cloud City experienced a total blackout . The previously imprisoned scientists helped Blissex and his team stock up on supplies before setting out for Bellum ' s shop , with Vreen in tow . On the way , they encountered several droids installing canisters full of the Evolution virus in the air vents , with approximately two hours until activation . Realizing that time was of the essence , the group hurriedly made their way to Bellum ' s shop . Meeting with Bellum , they asked her about Vreen and the keys he had commissioned for the seven locks that would guide them to X0 - X1 . Although the Forger didn ' t have the spare keys , she did know that one of them was for a maintenance corridor near K ' cri ' s Cafe . Bellum , however , did not have the keys themselves , as they had been stolen from her earlier . However , Vreen realized that they could find X0 - X1 by using the serial numbers on the keys . The group searched Bellum ' s shop for clues as to who might have stolen the cold box containing Bellum ' s copies and found some gold flakes , left by Iskraker ' s alien skin . Before the Rebels could track down the thief , Bellum was cut down by the fire of one of X0 - X1 ' s droids . After defeating the droid , Blissex and his allies realized that they would not be able to locate Iskraker , as only Bellum had known his location . Fortunately for them , they soon chanced upon Widget , a friend of Iskraker ' s . After some trickery and convincing , the Rebels were able to get Widget to lead them to Iskraker ' s ship , the " Erratic Orbit " . Catching up to Iskraker at hangar bay 487B , Blissex and his companions arrived to see the alien giving Lira Wessex the cold box . Some mercenaries working for Lira engaged the Rebels , giving Blissex ' s daughter a chance to escape . The Rebels overcame the distraction , and hunted the Imperial engineer down . Lira , who had recently had cybernetic implants installed , scanned the cold box for the key ' s serial number as she fled from her father and his men . During the chase , however , Lira was knocked off a ledge and was forced to request aid from the Rebels . Turning the tables on them , she threw the cold box away into Bespin ' s clouds , forcing Blissex and the Rebels to save her for her memory . Foiling X0 - X1 . Traveling to K ' cri ' s Cafe , Lira explained that Dr . Vreen had contacted her and informed her of X0 - X1 , which could be used to build weapons platforms by itself , as it was doing to Cloud City as they spoke . The Rebels the first lock , then progressed through all seven , battling all manner of traps and adversaries thrown at them by X0 - X1 . Reaching the Cloud City computer core where X0 - X1 resided , the group were confronted by Vreen , who had completed his transformation process and was now completely and utterly mechanical . He attempted to acquire Blissex ' s droid poison , but was destroyed by the Rebels . Despite this , they were unable to reach X0 - X1 , as the droid had a number of security measures in place protecting itself . Blissex realized that the only way to destroy X0 - X1 was to deactivate Cloud City ' s computer core . However , the core regulated Cloud City ' s generators , allowing it to float , and deactivating the core would cause the city to plummet for thirty seconds before being crumpled by Bespin ' s pressure . Blissex realized this , but insisted it was the only hope for the city . If the Rebels could destroy the droid within the thirty second time frame , the core could be re - activated , allowing the city to float once more . The Rebels executed the plan and were able to pull it off successfully , destroying X0 - X1 . Lira , however , took the opportunity to turn the tables once more on her father . Holding a blaster to Blissex ' s head , she gloated while a group of thugs she had hired to watch over her entered the room . However , Calrissian had been hiding in the core room the whole time with a detachment of his guards , and he chose that moment to reveal himself . Requesting that Lira leave the city , he dropped the murder allegations against Blissex and his men and thanked them for their services to Cloud City . Battle of Endor and the New Republic . In 4 ABY , Blissex was present aboard the " Home One " , in preparation for the climactic Battle of Endor . Blissex ' s expertise in the field of Star Destroyers gave him particular call to be present for the battle , as the Alliance would face a large amount of them over the Sanctuary Moon . In particular , Blissex provided the B - wing pilots with calculations and recommendations that would lead them to destroy one Star Destroyer during the battle and damage several others . Ironically , one of Blissex ' s A - wing starfighters would destroy the " Executor " , which was designed by Lira . The Endor briefing would prove to be one of the last times Blissex was seen in public . When the Alliance gave way to the New Republic , Blissex was Kuat Drive Yards ' top shipwright , but was alarmed by the galaxy ' s rush to war , and disturbed by the machinations of the Republic ' s war ministers and their ties to Kuat Drive Yards . Arch - Provost Bengila Urlan lured away Blissex to work for StarDrive , and thought he had crippled Kuat Drive Yards . However the New Republic already depended on the company ' s shipyards , hyperspace routes , and specialist deepdocks designed for new classes of massive capital ships , and Lira was also employed by Kuat Drive Yards . Blissex eventually retired from active service . Several years later , his friendship with Jan Dodonna would bring him back into the military fold . Blissex became a part of Dodonna ' s " Gray Cadre , " which served as a council of military advisors to the New Republic High Command . Amongst the battle hardened veterans that made up the group , Blissex was the most quiet and reserved of the lot . Blissex would later design the " Republic " - class Star Destroyer , an improvement and follow - up to his aging " Victory " - class . Though not as large as Lira ' s " Imperial " - class , it boasted 20 percent more firepower and only a fifth of the crew complement . Personality and traits . Walex Blissex tended to see issues in black and white , and apart from his refusal to comply with Palpatine ' s new regime , he would generally abide by the law . He was particularly disappointed to see his creations , such as the " Victory " - class Star Destroyer , turned into a symbol of terror by the Empire . Despite this , Blissex was proud of his creations . At heart , Blissex was a pacifist and idealist , which put him at odds with his daughter on several occasions . He chose not to speak out publicly against the reforms of 19 BBY ; rather , he chose to act , which was considerably more dangerous . As a pacifist , Blissex would again be disturbed at the New Republic ' s rush to conflict and the machinations of its war ministers . Blissex faithfully served the Alliance , but he had one weakness : his daughter . The nonreciprocating love he had for her allowed Lira to lure him into a variety of traps and use him as leverage . Blissex was always hurt deeply by Lira ' s machinations , and even though she had attempted to kill him , he was still crestfallen at the prospect of her death on the " Subjugator " . When she resurfaced shortly afterwards on Cloud City , he was not surprised , but rather disappointed that she was still trying to outwit and destroy her father in the name of the Empire . Behind the scenes . Walex Blissex was first mentioned in Bill Slavicsek and Curtis Smith ' s " The Star Wars Sourcebook " . His role as an engineer and designer would be elaborated and expanded upon , until " Starfall " , in which Blissex and his daughter Lira are pivotal characters . The two of them would also feature prominently in " Crisis on Cloud City " . Blissex was given a consistent depiction in both " Starfall " and " Crisis on Cloud City " , but he was later given the visage of an extra present in the briefing scene in , through the " Star Wars Customizable Card Game . " This depiction was later used in The Official Star Wars Fact File as the basis for an original illustration , despite the fact that it varied greatly from the original West End Games version of Blissex . The " Fact File " also gave Blissex a height of 1 . 94 meters , which differed from the West End Games height of 1 . 6 meters .
