Form VII / Legends Form VII , also known as Juyo , the Way of the Vornskr , or the Ferocity Form , was the seventh of seven forms recognized as canon for lightsaber combat by the last Jedi Council of the Old Jedi Order . In use , millennia prior to the Battle of Yavin , the Juyo incarnation of Form VII was described as the most vicious form of lightsaber combat and was said to involve significant internal focus on the part of the user . Juyo had many practitioners throughout the years , including Jedi Masters Kavar , Zez - Kai Ell , and Vrook Lamar . As time passed , knowledge of Form VII became restricted among the Jedi Order , whose members were worried that its precepts would lead practitioners toward the dark side . In contrast , members of the Sith , such as Darth Maul , employed Juyo without reservation , as did Dark Jedi such as Galen Marek . In the later days of the Galactic Republic , a new variation of Form VII , dubbed Vaapad after a creature native to the planet Sarapin , was created by Jedi Masters Mace Windu and Sora Bulq . Vaapad was explained as being a state of mind rather than just a fighting style , allowing the wielder to channel his own inner darkness into the duel , and accept the fury of the opponent . Windu , Bulq , and Windu ' s Padawan Depa Billaba were three notable practitioners of the Vaapad variant . Records of both Juyo and Vaapad survived the Great Jedi Purge and were recovered by the New Jedi Order , who preserved the records of Form VII into the Sith – Imperial War . Description . There were two variations of Form VII , Juyo and Vaapad , but both utilized bold , direct movements . According to accounts compiled by the New Jedi Order , use of Form VII was more demanding in terms of energy used due to a broader focus and deeper utilization of emotion . A Form VII practitioner was said to maintain a calm exterior appearance , but they were also stated to experience significant internal pressure , while using the Ferocity Form . In addition , it was described as sometimes paradoxical and unpredictable , as well as filled with concepts that made the form too difficult and unattractive to many students . Juyo . Juyo was described as the most vicious form of lightsaber combat , and was said to be filled with both fury and " malignant grace . " The form was given the title of the most difficult and demanding form in all of lightsaber combat . Skilled combatants with Juyo were said by Jedi Master Vrook Lamar to be able to " eviscerate a lone enemy " ; in fact , it was designed for such a purpose in one - on - one lightsaber duels . According to the Sith Lord Darth Traya , the form was both chaotic and erratic , with a heavy focus on offense . Juyo ' s use was controversial among the Jedi Order , as many felt that Juyo violated the " there is no emotion , there is peace " tenet of the Jedi Code due to its requirement to fight under the guidance of controlled passion . The Sith had no such inhibition , and Darth Sidious went so far as to label it a " Sith style " . Jedi Battlemaster Cin Drallig listed bold , direct motions as characteristics of Juyo , qualifying them as more open and kinetic than Form V , but with a less elaborate appearance than Ataru . Drallig contrasted the tactics of Juyo as not nearly as graceful or linked as those of Ataru , instead referring to them as " seemingly unconnected staccato sequences . " He also listed one of the strengths of the form as its unpredictability . The form was said to necessitate greater energy than Form V , due to a broader wielding of a user ' s focus and a deeper emotional link . Despite the challenges inherent in the use of the form , it could serve as a pathway to considerable power . Vaapad . Vaapad was described as more than a fighting style ; it was a state of mind that led through the penumbra of the dark side , requiring the user to enjoy the fight , and relish the satisfaction of winning . The practitioner of Vaapad would accept the fury of their opponent , transforming themselves into one half of a superconducting loop , with the other half being the power of darkness inherent in the opponent . The form was also mentioned with a cautionary warning by the Jedi that use of Vaapad led the user perilously close to the dark side due to its focus on physical combat . Vaapad required a constant and sizable stream of Force use from the user , with a barely contained explosion of Force power essential to all variations of Form VII as another prerequisite for its use . The form ' s attacks appeared to be unconnected , its motions seemingly unpolished to an untrained observer . During the later years of the Republic , Jedi Master Mace Windu developed Vaapad with the aid of fellow master Sora Bulq , by drawing inspiration from the movements of a creature , known as both the Vaapad and the Juyo , native to the planet Sarapin . Vaapad users appeared to wield many lightsabers at once , moving too fast to see , just as the vaapad creature would attack with blindingly fast tentacles that were impossible to count until the vaapad was dead . A Vaapad user ' s attacks would flow into each other with liquid precision , creating the constant near - invisible weave of energy which was the ready - stance of Vaapad . It was also possible to apply Vaapad in unarmed combat , with the user ' s arms becoming too fast to see , as well as in the use of dual lightsabers . While observing the duel between Darth Sidious and Mace Windu , Anakin Skywalker considered Windu ' s Vaapad bladework to be " an oblate sphere of purple fire " which contained dozens of blades attacking from every angle . After his fall to the dark side prior to the Clone Wars , Count Dooku described the power of Vaapad as skirting the dark side of the Force , but stated during a duel with Sora Bulq that the form was bridled and weak without direct use of the dark side . Dooku later subverted Bulq to his cause . After Bulq fell to the dark side , he claimed that he had perfected the form , which Windu disputed while engaging Bulq in a lightsaber duel . While Bulq had previously practiced Vaapad with Windu , he was unable to defeat him in combat and their duel ended in a stalemate . Though Windu and Bulq were credited with the creation of the Vaapad variant , the seventh lightsaber form was known , albeit obscurely , by the name Vaapad as early as the end of the New Sith Wars by the Sith Blademaster Kas ' im . Applications . Millennia prior to the Galactic Civil War , Juyo was ascribed the moniker of the " Ferocity form " due to its aggressive nature . Jedi Master Zez - Kai Ell claimed that Juyo was highly effective against an armed opponent , though much less against a foe skilled with the use of the Force . Master Kavar , a colleague of Zez - Kai Ell , advised Juyo for use in quickly overwhelming a single foe as well , but cautioned that it left one vulnerable to Force attacks such as those employed by Dark Jedi . Jedi of this era prescribed caution and control when using Juyo , and were loath to teach it to those with known recklessness , as the form ' s ferocity could lead them to the dark side . Juyo was said to be able to destroy even the defenses of a Form III master , but the practitioner was left vulnerable to counter - attack in the process , particularly from multiple opponents and Force powers . According to Jedi battlemaster Cin Drallig , who served in the final days of the Old Republic , Form VII was sufficiently demanding that only masters skilled in practicing multiple other forms were capable of utilizing it effectively . Drallig stated that the mastery required to learn Form VII was such that only a select few would be allowed to utilize it ; he forbade its study to all others . At least two users of its Vaapad variant during Drallig ' s tenure described the form as dangerous due to its focus on physical combat and intensity . For his part , Drallig refused to allow Anakin Skywalker to study Juyo , while Obi - Wan Kenobi was likewise forbidden to learn Vaapad by Qui - Gon Jinn . Windu also discouraged Quinlan Vos from learning Vaapad when Vos used it in a practice duel , learning from Vos that he had learned the move from Bulq and warning him against using it again , due to Vos already being perilously close to the dark side . Jedi Master Mace Windu , who developed Vaapad along with Weequay Jedi Sora Bulq , stated that Vaapad was an answer for his own weakness , allowing him to channel his own internal darkness into something positive . Furthermore , he said that he would not allow the use of the form without his permission , something that he had only given to his apprentice , Depa Billaba . Jedi Master Siri Tachi once explained to her Padawan , Ferus Olin , that the reason Mace Windu was able to dismiss the pleasure in power which Vaapad brought was by acknowledging it and being constantly aware of it . Windu wielded the form in numerous battles , especially in the Petranaki arena against bounty hunter Jango Fett , where his relentless use of Vaapad overpowered Fett . While dueling Darth Sidious in 19 BBY , Mace Windu ' s three Jedi companions were quickly brought down by the Sith Lord . In order to combat Sidious ' furious technique , Windu gave himself completely over to Vaapad . He allowed it to fully channel his own inner darkness , as well as accepting and using the darkness of Sidious . When fully immersed in his form , Windu ' s fighting prowess was such that he could allow his body to fight automatically for him without needing to direct it with his mind . Sidious ' own fury was used and redirected by Windu via the use of Vaapad , a process which Windu mentally likened to a lightsaber deflecting a blaster bolt back at its source . After Windu disarmed Sidious , the Sith Lord attempted to blast him with Force lightning , but Windu responded by once more employing Vaapad techniques to channel the dark power of the lightning through him without it affecting him ; he then redirected it back to its source . However , Windu believed that his use of Vaapad alone was insufficient to defeat Sidious , as he felt it would only result in a stalemate . Known moves and maneuvers . It should be noted that while the sequences and maneuvers of Form VII could be practiced and drilled , a duelist would not be truly executing the style unless they allowed the excitement and passion of battle to color their actions . The Form VII opening stance was a one - handed high guard with the blade held horizontally above the head and pointed to the side . The body was half - twisted , with the off - hand swept across and down . Juyo users were proficient in a technique called " Assured Strike " , wherein they traded sheer power for a near - certainty of landing a hit . Another technique they used was referred to as " Vornskr ' s Ferocity " , which involved " ferocious " attacking of an opponent . Wielders of Juyo were capable of employing this move without allowing the influence of the dark side to pervade their aggression . Those skilled in the Vaapad form were known for their use of the " Swift Flank " technique , where they leaped or dashed around an opponent to make a quick strike . The speed of the maneuver was intended to catch opponents off guard . They were also skilled in " Tempered Aggression " , a term used to describe the ferocity of the Vaapad form , but with more control against succumbing to the dark side even in the heat of battle . Practitioners . Juyo . Juyo was an established form of combat four millennia prior to the Battle of Yavin . Jedi Masters Vrook Lamar , Zez - Kai Ell , and Kavar were all skilled in its use and were able to pass on their experience to others . Jedi Master Atris , who fell to the dark side during the First Jedi Purge , was also known to employ the form . Jaric Kaedan , a Jedi Master who fought in the Great Galactic War , was a master of the form — which was known as Juyo - Kos by that time — and he was considered a living weapon guided by the will of the Force itself . Other Great Galactic War combatants , Jedi Master Gnost - Dural and the Sith Lord Scourge , also employed Juyo . The Sith Blademaster Kas ' im was a master of all seven forms of lightsaber combat near the end of the New Sith Wars , and the Sith apprentice Sirak , who was stationed on Korriban during Kas ' im ' s tenure there , was known to incorporate Juyo thrusts and jabs into his fighting style . Another Sith Lord of that era , Darth Bane , was proficient in the use of Juyo . During the conflict , use of Juyo caused many Jedi to fall to the dark side and join forces with the Sith . As a result the Jedi Council restricted the use of the Form , and in the time following the end of the conflict , the Jedi battlemaster Skarch Vaunk trained Juyo to only a few hand - picked students each year . Centuries later , in 32 BBY , when battling Jedi Master Qui - Gon Jinn and Jedi Padawan Obi - Wan Kenobi in Theed , Darth Maul employed a variant of Juyo against his opponents while wielding his double - bladed lightsaber . Maul ' s use of the form eventually broke through Qui - Gon Jinn ' s defenses , allowing him to slay the Jedi Master . Maul was devoted to the physical aspect of Form VII , as the Sith sought a purely physical victory over his two opponents ; for this outcome to happen , he had to keep the Jedi as far from each other as possible and kill them one at a time , given Juyo ' s weakness against multiple opponents . However , Form VII had fewer practitioners than other styles , due to its difficulty , complexity , and demands . Jedi battlemaster Cin Drallig and Grandmaster Yoda had knowledge and mastery of all seven forms , including Juyo , befitting Drallig ' s role as lightsaber combat instructor at the Jedi Temple and Yoda ' s reputation of having mastered all the forms of lightsaber combat as did Anoon Bondara , another lightsaber instructor . Lannik Jedi Master Even Piell was familiar with all seven forms of lightsaber combat , including Form VII . Furthermore , his Padawan , Jax Pavan , had some knowledge of the Juyo form , which he learned during his time in the Jedi Order . Another practitioner of Juyo was the grizzled Jedi General Rahm Kota , who survived both Order 66 and the Great Jedi Purge . Mace Windu , who went on to develop the Vaapad variant of Form VII , was also skilled in the use of Juyo . Darth Vader ' s secret apprentice , Galen Marek , was proficient in the use of Juyo . Marek used the form against both a vision of himself while on the planet Kashyyyk and against the fallen Jedi Maris Brood on Felucia in 2 BBY . Marek ' s droid companion , PROXY could use an imitation of the form , albeit without the Force , which he fought with while dueling Marek in the guise of Anakin Skywalker . After his defeat in the Duel on Mustafar , Vader himself utilized Form VII as part of his customized variant of Form V , employing some of its techniques when he killed the resistance fighter , Roan Lands , who was a good friend of the former Jedi Ferus Olin . Knowledge of Juyo in the book " " and records compiled by Jedi Master Cin Drallig was passed on to the New Jedi Order after the Great Holocron was recovered . The New Jedi Order then preserved this information into the Sith – Imperial War . Vaapad . Weequay Jedi Master Sora Bulq , already considered one of the Jedi Order ' s finest lightsaber practitioners and skilled in all seven forms , helped Mace Windu perfect Vaapad in the later years of the Republic . After the Battle of Geonosis , Bulq became disillusioned with the Galactic Republic and the Jedi Order and fell to the dark side . As was later said by Windu , Bulq did not master Vaapad ; Vaapad mastered him . Before falling , Bulq also taught Kiffar Jedi Quinlan Vos some maneuvers from Vaapad . Vos would later demonstrate his new talents inadvertently during a practice session with Mace Windu , who immediately recognized his move as part of Vaapad . Windu abruptly halted the duel , warning Vos not to use Vaapad again , as Vos was already considered to tread too closely to the dark side for him to safely employ Vaapad . However , while Vos was serving as a double agent for Count Dooku during the Clone Wars , he was encouraged by Bulq , who had by that time allied with Dooku , to take up Vaapad ' s power again . Mace Windu , in his private memoir , expressed concerns and suspected Vos has mastered Vaapad to a degree greater than Vos revealed . During the Siege of Saleucami , Dooku , Tol Skorr , and Sora Bulq prodded Quinlan Vos to give himself over to the dark side and to Vaapad , and Vos thereby demonstrated his level of mastery of Vaapad in his duel with Skorr and Sora Bulq , defeating both in lightsaber combat , and demonstrating his mastery of the flow of light and dark mastery of Vaapad requires as exemplified when Vos defeated his own inner demon . The only student Mace Windu ever taught Vaapad to was his own Padawan , Depa Billaba . Under Windu ' s instruction , Billaba became a master of Vaapad , with Windu considering her virtually unbeatable in personal combat . While on a mission with her master to Nar Shaddaa , Billaba and Windu were forced into a deadly confrontation with mutated giant akks . They barely survived the encounter , and Windu would later comment that on that day , Billaba had shown blade work that surpassed his own . While on a mission to Haruun Kal , Billaba fell to the dark side , allowing the blood fever of the jungle and the pull of Vaapad to take over . Mace Windu was forced to travel to Haruun Kal and face his student in a duel . Windu discovered that the only way he could survive against his former Padawan was to give all of himself to Vaapad , but realized that if he did , he would fall to the dark side as well . Turning away from the dark side , Windu conceded the fight , purposely opening himself up for Billaba ' s killing strike . However , Billaba , seeing what she had become , attempted to take her own life but was stopped by timely outside intervention . While fighting the cyborg General Grievous on Coruscant , Windu again displayed his mastery of Vaapad . Grievous responded by mimicking Windu ' s style , which resulted in what Windu considered a passable imitation of the form . Grievous had instructed his personal IG - 100 MagnaGuard droids in all seven forms of lightsaber combat , including Form VII . As with Juyo , knowledge of Form VII was recovered from " The Jedi Path " and the Great Holocron by the New Jedi Order , who preserved the information into the Sith - Imperial War . Behind the scenes . Form VII was first mentioned as part of the " " , though little information was given as to its characteristics or users , other than that it was employed by Jedi Master Mace Windu . Along with the other six classical saber forms , it was heavily described by David West Reynolds and fencer Jack " Stelen " Bobo for the " " " " part of " Star Wars Insider 62 " . This same source also retcon ed Darth Maul ' s use of Form VII in , while a StarWars . com web page derived from the " Fightsaber " piece later established that Mace Windu had wielded Vaapad against Jango Fett in . Form VII was then expounded upon in numerous other sources , including " " , " " , and numerous supplementary works and RPG guides , which expanded its list of practitioners and established Juyo as a known form circa the Jedi Civil War . The Clone Wars novel " Shatterpoint " had a large focus and considerable description on the Vaapad variant , as two of the chief characters , Mace Windu and Depa Billaba , were masters of the form . Several issues of comics set during the Clone Wars , including " " from the " " story arc , as well as " " and " " , featured Vaapad in a substantial role , due to the involvement of Mace Windu and Sora Bulq . Both Juyo and Vaapad were extensively described in the 2007 reference book " " , which provided an entry for Form VII , as well as a longer description of Vaapad . " The Essential Guide to the Force " established that knowledge of the seven forms , including Juyo and Vaapad survived into the Legacy era . In the video game " Star Wars : Knights of the Old Republic II : The Sith Lords " , the Jedi Masters could teach the Jedi Exile the Juyo form only if she was Jedi Guardian or its corresponding prestige classes , the Jedi Weapon Master or the Sith Marauder . The Sith apprentice Sirak in " Darth Bane : Path of Destruction " was stated to be a Vaapad practitioner , long before the style was created by Mace Windu . At a book signing in Huntington Beach , California , author Drew Karpyshyn said , " I meant Juyo , but it was a late night when I wrote that and didn ' t catch it until it was too late . That ' s one mistake I wish to God I could change . So when you read it and see ' Vaapad ' , just pretend it says ' Juyo . ' " " Star Wars Insider 92 " later explained it by stating that " juyo " was another term for the vaapad creature the form was named after . Form VII , along with the other lightsaber forms , appears in " Star Wars Galaxies " as part of moves and techniques employable by Jedi characters . This has not definitively been clarified to be canon ical . Form VII is displayed as part of the non - canonical guest appearance of Darth Vader in the fighting game " Soulcalibur IV " as part of Vader ' s repertoire of moves .
