Omega Frost / Legends The Omega Frost was a superweapon designed by Doctor Silas Tagge of the Tagge Company and implemented by the Galactic Empire in a failed attempt to destroy the Alliance Fleet . The Omega Frost was devised to flash - freeze any moisture - containing object — including a living being — that happened to be positioned between two strategically placed conductor tower s ; material frozen by the weapon , even metal , subsequently shattered . As almost every substance in the galaxy contained some degree of moisture , the weapon could be utilized in any environment , including the vacuum of space . In 0 ABY , Baron Orman Tagge , head of the House of Tagge and brother to Silas Tagge , moved forward with the Omega Frost ' s production . Establishing a testing facility in the Jundland Wastes on arid Tatooine , the Baron and his brother oversaw a successful trial of the weapon ' s effects within the planet ' s deserts ; even under the intense heat of the system ' s twin suns , the landscape — and everything on it — froze . With the testing complete , the Tagge brothers departed Tatooine for the Feriae system , where they prepared to use the weapon to destroy the Alliance Fleet . The Imperials had not been the only ones to observe the Tatooine demonstration , however ; Rebels Luke Skywalker , Han Solo , and Chewbacca had almost fallen victim to the Omega Frost themselves and vowed to uncover the Tagges ' plans . The Tagges planned to unleash the Omega Frost on the unsuspecting Alliance Fleet within the Feswe Corridor , using more advanced conductor towers to generate the weapon and flash - freeze the Rebel ships . Skywalker attempted to destroy one of the towers before the Rebel Fleet could fall into the trap , prompting Doctor Tagge to prematurely activate the Omega Frost . The Alliance forces narrowly avoided the effective band of the weapon before Skywalker destroyed the tower and stopped the Omega Frost ' s generation . With the weapon inactive , the Rebel ships proceeded through the Feswe asteroid corridor unmolested , taking the opportunity to destroy the Tagges ' Mining Explorer and an Imperial battlecruiser . The engagement put an end to the Omega Frost , though a conceptual cousin , the Metal - Crystal Phase Shifter , survived into the time of the New Republic and the Galactic Alliance . Description . The Omega Frost was a superweapon capable of flash - freezing objects of any size — including sentient beings — to temperatures below the mark of absolute zero through the use of force fields and electromagnetics . The weapon was capable of freezing an entire planet and functioning properly in the vacuum of space . Theoretically , it could even freeze an entire star system . The Omega Frost ' s effect was generated by two conductor tower s ; when these towers were activated , any object containing moisture that happened to fall between both conductors ' effective band — even the terrain — was instantly frozen . The effect was so powerful that even metal shattered after the freezing process . History . Development and testing . Conceived by Doctor Silas Tagge of the Tagge Company , the Omega Frost was Tagge ' s crowning achievement . Baron Orman Tagge , head of the House of Tagge and Silas ' s older brother , planned to use the Frost as a means by which the Galactic Empire could destroy the Rebel Fleet that had been using the Feswe Corridor to break the Imperial blockade of Yavin 4 . The Baron believed an effective use of the weapon would curry Emperor Palpatine ' s favor , at the same time granting Tagge the revenge he desired against the Emperor ' s enforcer , Darth Vader . The Baron included his younger brother , General Ulric Tagge of the Imperial Military , in the plot as a means of securing Imperial assistance for the project . Doctor Tagge tasked his older brother with selecting an arid world on which the Omega Frost could be tested . Baron Tagge found many locations that fit his brother ' s conditions , but only one stood out to him — Tatooine , a desert planet that happened to be the homeworld of a young Rebel hero named Luke Skywalker , whom the Baron hoped he could lure to Tatooine with word of the project . The Tagges purchased several moisture farms on the planet and set up their headquarters in the rocky hills of the Jundland Wastes , from which they began experimenting with the Omega Frost . One subject , a bantha , managed to escape the facility , but the Omega Frost took effect before long , freezing and killing the bantha in its tracks below the heat of the Tatoo system ' s twin suns . The security breach did not overly concern Baron Tagge , as the project was quickly nearing completion . Skywalker did arrive on Tatooine , but for reasons unrelated to the Tagges ' secret project . En route to the city of Mos Eisley to recruit blockade runners for the Rebellion , Skywalker happened upon the frozen remains of the escaped bantha in a narrow canyon . An Imperial Reconnaissance Troop Transporter searching for the creature discovered it at the same time that Skywalker did ; the young Rebel managed to avoid detection as a pair of Imperial stormtroopers proceeded to obliterate the bantha ' s remains to conceal any evidence of the Omega Frost . Having learned previously that the House of Tagge had bought up moisture farms , Skywalker concluded that they were behind the bantha ' s mysterious death , and he vowed to uncover what exactly was going on . The Imperials eventually learned of Skywalker ' s presence on Tatooine , forcing him to flee with fellow Rebels Han Solo and Chewbacca into the desert , where they happened upon the Jawa crew of a sandcrawler that aided in their escape . Concurrently , the Tagge Company proceeded with their experiments with the Omega Frost . Two conductor towers were established within the Tatooine desert to test the Frost ' s effect ; Skywalker and company discovered both towers when the Jawa crew of the sandcrawler happened upon one of them during their trek . They originally mistook it for a giant moisture vaporator , but upon closer inspection , Skywalker realized the tower was rapidly getting cold . Remembering the frozen bantha he had stumbled upon earlier , he urged everyone to flee . The three Rebels succeeded in getting the Jawas out of the way before the Omega Frost took effect , but another sandcrawler and its crew were caught between both towers and instantly frozen with the surrounding terrain . Stunned by the field of ice before them , the Rebels and the Jawas watched as the second sandcrawler shattered . A Reconnaissance Troop Transporter arrived on the scene with the Baron and Doctor Tagge aboard ; they marveled at the success of the Omega Frost before ordering the capture of the Rebels , who managed to elude the Imperials and flee Tatooine . Upon departing Tatooine aboard the freighter " Millennium Falcon " , Skywalker and his companions followed Baron Tagge ' s Mining Explorer to the planet Feriae Junction , hoping to uncover more details about the weapon they had witnessed . Trap at Junction . At Feriae Junction , Baron Tagge oversaw the transfer of Omega Frost components to his brother Ulric ' s battlecruiser . When the " Millennium Falcon " arrived in the Feriae system , Skywalker donned survival armor and slipped in among the workers handling the cargo transfer . Eavesdropping on the comm chatter , he learned of the Omega Frost ' s ability to freeze an entire world . Believing Junction — a key source of supplies to the Rebellion — to be the target , Skywalker contacted the " Falcon " and told Solo to warn the Alliance about the impending use of the weapon ; before Skywalker could flee , he was stunned by Imperial stormtroopers and was brought aboard Tagge ' s Mining Explorer . The Baron revealed the details of his plan to the captive Skywalker ; rather than freeze Junction with the Omega Frost , Tagge revealed , the weapon was intended to destroy the Alliance Fleet as it journeyed through the Feswe Corridor . Skywalker was able to overcome the Baron in a brief lightsaber duel before escaping the Mining Explorer in a TIE fighter that had been covertly rigged by Doctor Tagge . As Skywalker fled , two conductor towers — substantially larger than the two used on Tatooine , and possessing a far greater range — were installed on asteroids at opposite ends of the corridor in preparation for the Alliance Fleet ' s arrival . The Tagge Mining Explorer detected the approaching fleet on its long - range scanner s as it moved away from the target zone . When the fleet was midway into the corridor , Doctor Tagge planned to activate the Omega Frost and immediately freeze the Rebel ships and their crews . Skywalker , meanwhile , decided to do whatever he could to prevent the Tagges from fulfilling their plans . Having abandoned his doomed TIE fighter , Skywalker used the jetpack built in to his survival suit to navigate the asteroid corridor , searching for one of the conductor towers . He arrived at the first of the towers and attempted to destroy it with his lightsaber , only to have the attack deflected by the tower ' s force field . Skywalker ' s move prompted Doctor Tagge to activate the Omega Frost prematurely , freezing a large number of asteroids . The Rebel ships were just beyond the weapon ' s effective band when the Frost activated , however , but as they lacked the maneuverability to avoid the weapon , they would either proceed forward and be frozen , or attempt to turn only to collide with one another . With moments to spare , Skywalker realized that the conductor tower ' s force field did not extend below the asteroid ' s surface . He quickly dug into the rock with his lightsaber and slashed at the vulnerable components of the tower beneath the surface . The move shorted out the conductor tower , shutting down the Omega Frost just as the Rebel Fleet pressed forward into the corridor . Stunned by his failure , Doctor Tagge ordered his subordinates to call in reinforcements from his brother , General Ulric Tagge , before rushing out to find the Baron . The Mining Explorer ' s military liaison officer , Lieutenant Shanks , realized only too late that such a transmission could be detected and pinpointed by the Alliance forces — the Rebel ships moved in on the Tagges ' cruiser and destroyed it , before turning on and destroying General Tagge ' s battlecruiser . The battle marked the end of the Omega Frost . Legacy . Although the Omega Frost weapon ' s destruction was confirmed by Crix Madine , the Rebel general held suspicions that the technology for it was still out there . This suspicion was later confirmed when a conceptual cousin of the Omega Frost known as the Metal - Crystal Phase Shifter survived into the reign of the New Republic and the Galactic Alliance . The Metal - Crystal Phase Shifter possessed the ability to alter the molecular structure of metal , turning it into a powder . The effects of the weapon were sufficient enough to severely damage the hull of a starship . Creators . Silas Tagge . Chief scientist of the House of Tagge , Doctor Silas Tagge was the creator of the Omega Frost , which proved to be his crowning achievement . Whereas his brother , the Baron , plotted to use the weapon to settle vendettas and secure the Emperor ' s favor , Doctor Tagge was more concerned with ensuring the Omega Frost ' s success — though he was not adverse to becoming the next Baron when his brother was temporarily incapacitated . He took extra precautions to prevent Luke Skywalker from interfering in his plans , but he underestimated the young Rebel ' s chances . When Skywalker succeeded in shorting out one of the conductor towers , disabling the Omega Frost , Doctor Tagge was stunned by his failure and rushed to awaken his brother , hoping he could remedy the situation . Before anything could be done , the Rebel Fleet destroyed their Mining Explorer . Both Tagges narrowly survived the encounter , however , and were placed in life support capsule s aboard Darth Vader ' s flagship . Orman Tagge . Unlike his scientist brother , Baron Orman Tagge plotted to use the Omega Frost for his own personal gains , using the resources available to him as the head of the House of Tagge to ensure the project met completion . The Baron hoped that a successful demonstration of the weapon would earn him the Emperor ' s favor , simultaneously fulfilling a vendetta he held against Darth Vader , who had blinded him earlier in his life . Tagge hoped to eliminate another of his rivals , Luke Skywalker , by drawing him to Tatooine with word of the Omega Frost , but the Baron ' s underestimating of the young Rebel proved disastrous . Skywalker bested Tagge in a brief lightsaber duel , placing the Baron in a state of shock and leaving the fate of the project in his brother Silas ' s hands . Doctor Tagge ' s personal ambitions got in the way , and as Skywalker disabled the Omega Frost , he rushed to get his comatose brother ' s assistance . Baron Tagge awoke just as the Rebel ships succeeded in destroying the Mining Explorer . He and his brother were recovered by Imperial forces and placed in life support capsules aboard Vader ' s flagship . The Baron later met his end at Skywalker ' s hands on the planet Monastery . Behind the scenes . The Omega Frost first appeared in , issue 31 of the " Marvel Star Wars " line of comics . The weapon went on to appear in issues ; ; and . The weapon later received entries in " The Complete Star Wars Encyclopedia " and " Galaxy of Intrigue " . In 2008 , the Omega Frost was featured in issue 209 of StarWars . com ' s biweekly newsletter , the " Homing Beacon " . The reference to the weapon was done in the style of , an article that had appeared on StarWars . com only a few days prior . In addition to detailing the origins , functions , and flaws of the Omega Frost , the newsletter also pokes fun at the weapon , comparing it to a gardening tool and claiming it has a " non - draconian " potential for preserving leftovers .
