Jecht / Dissidia Jecht was one of Cosmos ' s champions during " Dissidia 012 Final Fantasy " , but during the war , he is recruited into one of Chaos ' s minions . In " Dissidia Final Fantasy " , Jecht is forced to fight his rival and son , Tidus . Jecht was once a famous Blitzball player from Zanarkand . Burly and rough - spoken , Jecht ' s style of brawling is straight from the Blitzball arena . Similar to Golbez , he does not care about the other villains ' plans , but is hinted to fight for his own , more benevolent desires . Jecht also appears to his son Tidus , who wishes to settle their grudge and finally best his father in battle . Attire . Jecht ' s appearance is similar to his " Final Fantasy X " design . He wears black shorts with an orange and red sash over his right leg and bears a large black tattoo of the Zanarkand Abes logo on his chest . He wears a red bandanna , a metal gauntlet on his left arm , and carries a large black sword . Elements of his Final Aeon form have been added , giving him clusters of spikes under his sash and emerging from his left shoulder . In his first alternate outfit , Jecht ' s sash and spikes turn red , and his sword gains red colorings with gold details , a reference to Auron ' s color scheme and of the Masamune . In " Dissidia 012 " , Jecht ' s first alternate outfit is replaced with a new outfit based on his original " Final Fantasy X " appearance , named " Road Uni " . Jecht ' s clothing is no longer torn , his sash has a lighter color gradient , he bears no spikes , and his gauntlet and hair are differently designed . His EX Mode remains identical in appearance between the two outfits , a primarily green Final Aeon with purple claws and orange trimmings on the edge of his leg sash . Jecht ' s second alternate outfit is named " Abes Uni " . based on the Zanarkand Abes uniform as seen in the " Final Fantasy X " introductory sequence . His shorts are longer with a gray and black pattern , he wears blue and black coverings over his lower arms , and has a darker headband . His Final Aeon spikes and the cloth over his leg are absent in this outfit , and he remains shirtless and barefoot . This is Jecht ' s attire in " Dissidia 012 " as a Warrior of Cosmos and in the opening FMV . His EX Mode in this outfit is a dark purple Final Aeon with orange claws , meant to resemble the as it appeared in the lighting of Dream ' s End . His shorts in his Final Aeon form are shorter to match the length of his shorts in his other outfits , but retain the gray and black coloring . Jecht ' s manikin version , Ephemeral Phantom , is orange . Story . Twelfth cycle . During the twelfth cycle of war , Jecht serves as a warrior of Cosmos . At some point during the conflict , he converses with Kain about trying to open up a bit towards his allies , as they are becoming somewhat nervous about his loner attitude . He also briefly suggests to Lightning that she fight alongside the Warrior of Light to determine for herself if he is trustworthy . He accompanies Yuna after she is separated from her group , only to lose sight of her . He eventually is confronted by Tidus , who had joined Chaos in an attempt to defeat his father . Tidus tries to provoke Jecht into fighting him , with the man calling him an idiot for being brainwashed . Before the two can battle one another Yuna intervenes to protect Jecht and reason with Tidus when the Emperor appears and attacks . Tidus takes a fatal blow for Yuna , and Jecht , refusing to let his son die , saves him by giving him Cosmos ' s light , rendering Jecht an empty vessel . The Emperor spirits Jecht away to Chaos ' s throne , where Chaos fills Jecht with the power of discord and converts him into his newest agent . Thirteenth cycle . Jecht is recruited by the Emperor to battle Tidus on the promise that when the Emperor ' s plan reaches fruition , he and Tidus will be able to return to their world . Golbez suspects the Emperor will betray Jecht and meets with him several times to warn him so . When Tidus and Firion split up , Jecht confronts Tidus at the Emperor ' s palace Pandaemonium , ready to fight . The Emperor intervenes and tells Jecht that Tidus wishes to fight him due to hatred , which is against their intended plan . Though disgruntled , Jecht departs and leaves the Emperor to battle Tidus . Jecht comes across Firion at the Lunar Subterrane , and the latter questions if Jecht ran from his fight with Tidus . Annoyed by the implication , and by the Emperor dismissing him , Jecht attacks Firion to take out his frustrations . After the fight , Jecht seems unfazed as Firion stands exhausted . Jecht wishes to keep going and Firion refuses , saying he will not be a substitute for Tidus . Jecht agrees and leaves , deciding the Emperor needs to stop meddling . Heeding Firion and Golbez ' s advice , Jecht turns on the Emperor and the two do battle as Firion and Tidus find them . The Emperor teleports away as Jecht kneels injured , telling him to fight Tidus as much as he likes . Jecht prompts Tidus to battle him , but Tidus refuses to fight Jecht when he is hurt . Jecht leaves , and Tidus splits from Firion to follow . Following Jecht to Dream ' s End , Tidus uses a potion from Firion to heal his wounds . Now content to fight with his father at his full strength , Tidus and Jecht battle . In the end , Tidus is victorious and claims his Crystal . Jecht begins to fade , and Tidus tearfully admits he only ever wanted his approval . Jecht chuckles as he vanishes , his last words to compliment Tidus on his strength . With Cosmos gone , the Emperor reveals to Jecht the cycle will no longer begin again , and that both they and the heroes will eventually vanish . The Emperor further reveals Jecht ' s origins as a warrior of Cosmos and how his fight against Tidus was planned so the Emperor could create his own Crystals , attuned to warriors of darkness rather than light , in order to survive the destruction of the world and Chaos to rule existence . Disgusted , Jecht leaves to find a good fight and finds Tidus , telling him a true ace never stops until the end . The two battle , and Jecht is again defeated . Jecht goads Tidus , telling him to accept his weakness and that the world they are in makes no sense . When Jecht asks if Tidus will cry , Tidus tells him to shut up . Pleased with his son ' s resolution , Jecht rises and begins to walk away as pyreflies float up from his body . Jecht warns Tidus " don ' t make ' him ' come out here again , " and vanishes , telling Tidus it was fun being his father . If a Warrior of Cosmos other than Tidus encounters Jecht , Jecht notes that Tidus isn ' t around , and decides to fight the Warrior of Cosmos anyway , since that ' s what they came for . After being defeated , he remarks they aren ' t bad , and he won ' t have anything to worry about . Official Quests . Jecht appears in " Bartz ' s Quest 012 : Mimicry And a Promise " . Bartz , Laguna and Jecht are looking for treasure and decide to take a break when their searches prove fruitless . At this time Bartz challenges Laguna to battle , wishing to learn how to mimic his attacks . Laguna accepts and Bartz successfully learns to copy his Ragnarok Blade . Bartz challenges Jecht to learn his attacks as well , but Jecht refuses , saying his attacks are harder to mimic and he ' ll teach them to Bartz later . Battle . In battle , Jecht is a Brutal Blitzer . Jecht ' s attacks are fast , powerful combos of kicks , punches and sword blows that change in effect and power depending on the timing of button presses during the attack . Properly timed , Jecht ' s combos are some of the strongest in the game , and all of them link to HP attacks . Additionally , almost all of Jecht ' s offensive attacks can be charged , giving them longer range , more hits , and the ability to crush guards . Jecht Block is a guard that deflects any attack , even those that normally crush guards . Only attacks that strike from directly above or below , like Flood or Starfall , as well as certain attacks that land multiple hits , can penetrate Jecht Block . Jecht moves fairly fast on the ground compared to similar heavy - hitting characters , but his combos are difficult to master , and though he charges forward while attacking , he is ultimately a melee fighter . Boss . In " Dissidia " , Jecht is fought in Destiny Odyssey II , X , Shade Impulse , Distant Glory and Inward Chaos . In " Dissidia 012 " , he is fought in Entrusted Power , Seeds of Hope , and Conclusion of the Cycle chapters of Story Mode . EX Mode . Jecht ' s EX Mode is his Final Aeon form from the final battle in " Final Fantasy X " . In his EX Mode Jecht gains the ability " Full Combo " , letting him continue his Bravery combos even if the initial strike misses . This lets him overwhelm opponents with powerful combo attacks , and also makes it easier to strike when pausing to charge up his attacks . Jecht ' s EX Burst is Blitz King , his variation of Tidus ' s signature Blitz Ace . Jecht attacks enemies by kicking them into the air , slamming them back down , and then impaling them with his sword and leaping into the air . Two timer meters appear as Jecht kicks a boulder apart and then kicks the shards at the opponent . The player must press to stop the cursor as it moves back and forth across the meter , and the closer to the middle of the meter the cursor is stopped , the more pieces Jecht shatters the boulder into before kicking them at the opponent . Two " Great ! " ratings causes the rubble to circle out and converge on the opponent and explode , similar to Tidus ' s Energy Rain . Equipment . Jecht can equip Greatswords , Axes , Grappling Weapons , Shields , Bangles , Hats , Helms , Clothing and Light Armor . In " Dissidia 012 " , Jecht can also equip Thrown Weapons , Headbands , and Chestplates .
