Jecht ['dʒɛktʰ] is a non-player character and a reluctant antagonist in Final Fantasy X. He is Tidus' 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.
He is voiced by Masuo Amada in the Japanese version, and by Gregg Berger in the English version.
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.
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.
