Jecht Jecht [ ' dʒɛktʰ ] is a non - player character and a reluctant antagonist in " Final Fantasy X " . He is Tidus ' s father , was one of High Summoner Braska ' s legendary guardians , and a major blitzball star in his hometown . Jecht is a tall , muscular man , with a tendency to drink heavily , and wields a large black sword in battle . Profile . Appearance . Jecht is a dark - skinned , muscular man with long unruly black hair and red eyes . He wears a pair of black shorts with an orange and red sash covering his right leg , a red headband , and a metal gauntlet covering his left arm . His outfit appears to be a Zanarkand Abes jumper , similar to Tidus ' s uniform , with the straps undone . He has a black tattoo of the Zanarkand Abes symbol on his chest . In his concept art and in " Dissidia Final Fantasy " Jecht wields a black sword with red markings that resemble dolphins . He never wields the sword himself in " Final Fantasy X " . Braska ' s Final Aeon , on the other hand , wields a larger version of it , and Jecht is mentioned to have fought with a sword during Braska ' s pilgrimage . As Braska ' s Final Aeon , Jecht is a large , deformed version of his former self with brown scales and horns with crests of spikes emerging from his back and shoulders . He wears a larger version of his headband , his hair is white and emerges in tufts from the spikes around his head , and his eyes glow . His Zanarkand Abes tattoo is white , and his body below the waist has another large crest of spikes partially covering his legs . His right hand is of normal proportions to his body , and is used to wield his sword , while his left hand is a large claw . Personality . Jecht is surly , arrogant and a bully . He frequently refers to himself as " The Great Jecht " ( " Jecht - sama " in the Japanese releases , giving himself a respectful , in this case arrogant , honorific ) , and is known to Spira as " Sir Jecht " for being a famous guardian . Jecht considers himself the best blitzball player there is and loves fame and glamor , asking Braska several times if there will be celebratory events on their pilgrimage . Jecht ' s career hit a slump when he began drinking , and it was rumored he was going to retire , though he was quick to deny this and claimed he could quit drinking if he chose . Jecht used to be emotionally abusive to Tidus , giving him the nickname " crybaby " , and otherwise brushing him off or berating him . Despite his numerous flaws , Jecht is a good man at heart . He criticizes Tidus in the hope of encouraging him to try harder and disprove him . Jecht does love Tidus , but struggles expressing it : a sentimental message to Tidus on a sphere is cut off with Jecht mumbling , " " Remember , you ' re my son . And . . . well , uh . . . never mind . I ' m no good at these things " " . A flashback shows Jecht telling Braska and Auron his dream is to train Tidus into a star blitzball player like himself . Jecht enjoys the " Hymn of the Fayth , " and is well - loved by his fans to the extent of a blitzball tournament in dream Zanarkand being named in his honor . When the party learns about the Chocobo Eater and Tidus says they must help because " it ' s the right thing to do " , Auron laughs and explains Jecht used to say the same thing , which ended up causing problems for the group . " Jecht ' s Real Story " from " Final Fantasy X Ultimania Omega " elaborates on his personality . He had been criticised as hating practice , yet he made frequent training trips out to sea . Jecht may have been concealing how hard he trained , preferring to appear " naturally talented " . His claims of being the best could have also risen from a personality wherein he couldn ' t maintain his confidence without bragging . The memory of Tidus in Jecht ' s mind remains as that of a 7 - year - old boy . Jecht continues to cherish that image of a son who needs protection , and dreams of him growing up . Fragments of Jecht ' s feelings can be seen from the illusions which occur whenever Tidus comes into contact with Sin ' s toxin . Story . " Final Fantasy X " . Jecht and Tidus ' s mother loved each other and she fell into depression and died when he vanished . Before he disappeared from Zanarkand , Jecht was a famous blitzball player , but his career had hit a slump due to his alcoholism , and there were rumors he was planning to retire , though he denied them . Jecht went to train at the sea to regain his former glory and it was the last he was ever seen . The vanished Jecht became a near legendary figure in Zanarkand , with billboards featuring him and an annual blitzball tournament being named for him . Jecht had entered Spira after coming upon Sin . According to the fayth of Ifrit , Sin swam in these waters to ease its pain on that day ; as Jecht touched him , " he became real " , and was washed ashore somewhere near Bevelle . The Zanarkand he hailed from , as well as Jecht himself , were but a dream recreation of the original city , created from the memories of its original citizens and maintained by Yu Yevon , the summoner who was the original Zanarkand ' s leader a thousand years ago . The dream Zanarkand is based on Zanarkand as it existed a millennium ago in Spira ' s history , whose ruins have since become the destination of summoners ' pilgrimages . Unaware of any of this , Jecht was seen as a crazy drunkard and locked up in Bevelle . A former priest named Braska visited Jecht and requested he become his guardian along with Auron , a warrior monk of Bevelle who had fallen from grace . Auron , wary of Jecht , objected , but Braska thought it the perfect irony for three of the most unlikely people to defeat Sin : a drunken blitzball player from Zanarkand , a summoner with a " heathen " Al Bhed wife and a " half - breed " daughter ( Yuna ) , and a disgraced warrior monk who had refused to marry the daughter of a high priest . Before they departed , Jecht told Yuna stories about his Zanarkand . During the earlier parts of their journey Jecht ' s carousing got him into trouble , most notably at the Moonflow where he mistook a shoopuf for a fiend and wounded it , forcing Braska to pay for the damage with their travel money . Afterward Jecht gave up drinking anything stronger than shoopuf milk for fear his family would be ashamed of him , and out of embarrassment for what he had forced Braska to do . Jecht recorded their journey to show his wife and Tidus , still hopeful he would find a way home some day . Over the course of Braska ' s pilgrimage Jecht matured as he learned about Spira and what became of Zanarkand . His journey mirrors what Tidus would go through a decade later . According to Auron , Jecht would suggest helping people along the way because it is " the right thing to do " , which always led to trouble for the three . Jecht came to accept he was trapped in Spira with no hope of returning to his Zanarkand , and left behind spheres to guide Tidus ' s journey should the same fate befall him . By the time they reached Zanarkand Ruins the trio had become close friends , and Jecht offered to give up his life to become Braska ' s Final Aeon , knowing he could never return home . As one last favor Jecht asked Auron to look after Tidus , believing Auron could find a way to dream Zanarkand . Though Auron protested Jecht ' s choice , knowing Sin would return , Jecht assured he ' d think of a way to stop Sin ' s reincarnation . Although Jecht defeated Sin as Braska ' s Final Aeon the " spiral of death " surrounding Sin continued ; Yu Yevon ' s spirit possessed Jecht and transformed him into the core of a new Sin , leaving Jecht ' s soul trapped within the creature for ten years . Struggling to fight the powerful instincts Yu Yevon had instilled within Sin , Jecht can momentarily operate of his own volition for the brief moments he hears the " Hymn of the Fayth " . The now - unsent Auron rode Sin to dream Zanarkand where he looked after the orphaned Tidus , watching him follow his father ' s footsteps in becoming a star player for the Zanarkand Abes . One day , Sin attacks dream Zanarkand and transports Auron and Tidus to Spira . As Auron looks up at Sin he asks " Are you sure ? " , suggesting he is communicating to Jecht ' s consciousness . Jecht hopes that Tidus would find a way to destroy Sin for good , a wish shared by the fayth with Bahamut ' s fayth asking for Tidus ' s help before he is sucked into Sin . While in Spira , Tidus reminisces about Jecht , not suspecting Sin is his father . When Auron reveals the truth , Tidus rejects the notion , but eventually senses Jecht within Sin , and his desire for Tidus to free him from being forced to destroy Spira . During Operation Mi ' ihen Sin decimates the joined forces of the Crusaders and the Al Bhed , and afterward a raging Tidus chases Sin out to sea before collapsing . Auron explains the reason Sin showed up was to see Tidus . Later on Tidus and his comrades are stunned to find Sin complacently listening to the " Hymn of the Fayth " beneath the ice in Lake Macalania , the song Jecht enjoyed as a human . Tidus accepts what he must do and promises Jecht he will find a way to end the cycle and free him . Using the " Fahrenheit " to broadcast " The Hymn of the Fayth " across Spira , Tidus ' s group brings all of Spira together in song , calming Sin momentarily , allowing them to fight their way through the beast ' s innards and confront Jecht at Sin ' s core . Able to speak to his son a final time , Jecht asks Tidus to finish him , as he is almost consumed by Yu Yevon and fears he will soon be unable to " hear the hymn " any longer . Jecht transforms into Braska ' s Final Aeon , and is defeated by Tidus and his allies . Dying , Jecht and Tidus make peace and Jecht enters the Farplane . Yuna uses her aeons to weaken Yu Yevon ' s spirit making him vulnerable for the first time in a thousand years . After the group destroys Yu Yevon and ends Spira ' s spiral of death , dream Zanarkand and its inhabitants fade away , including Tidus . In the Farplane , Jecht is reunited with his son with the two slapping a jovial high five . " Final Fantasy X - 2 " . Jecht appears in a flashback from the scholar Maechen during Chapter 5 at the Zanarkand Ruins . When Yuna fights Vegnagun in the Farplane , the voices of Jecht , Braska and Auron encourage her and advise her party on where to strike Vegnagun . As Shuyin resembles his son , Jecht calls him a crybaby and claims he needs a " good spanking " . Jecht appears in the Cactuar creature ending in " Final Fantasy X - 2 International + Last Mission " and the " HD Remaster " versions . Gameplay . Jecht is fought at the end of " Final Fantasy X " as Braska ' s Final Aeon . As the fight with Yu Yevon is commonly considered a mere story formality due to the ease with which he is defeated , Braska ' s Final Aeon effectively acts as the game ' s final boss . Creation and development . Daisuke Watanabe considered having Auron be Jecht in disguise , watching Tidus throughout his journey , but the team did not want to give Jecht a leading part in the story so they gave up on the idea . It has been said Tidus and Jecht ' s relationship invokes the timeless theme of " a child trying to exceed the achievements of their parent " . The bond between parent and child becomes a key factor in finding the chink in Sin ' s armor that allows for this otherwise invincible creature to be defeated . During development of " Dissidia Final Fantasy " , Jecht ' s inclusion over Seymour Guado was influenced by their respective relationships with Tidus and Yuna in " Final Fantasy X " . Development staff believed that as an antagonist Seymour was more suitable to oppose Yuna rather than Tidus if she were to be included , and so Jecht was included instead to make Tidus ' s rivalry with his game ' s representative villain more personal . This gave the development staff the chance to expand on their relationship , as their interactions in their original game were limited . Voice . Jecht ' s voice is provided by in Japanese , and Gregg Berger in English . Musical themes . " Jecht ' s Theme " is a laid - back melody with steel - stringed guitar solos following Western style , performed by Tsuyoshi Sekito . It appears in the as the second track of Disc 3 . The music that plays during the final confrontation against Braska ' s Final Aeon within Sin is " Otherworld " , a heavy metal style song with English lyrics that was uncommon for a " Final Fantasy " game . The only other time the song plays is during Sin ' s attack on dream Zanarkand in the opening FMV . Other appearances . Jecht has made appearances in the following games in the " Final Fantasy " series : Other media . In " " , a costume based on Jecht was released in November 2014 .
