Yo-kai Medallium biography
"The guardian of the High Summoner of Braska. From another world, he is sent to Spira and shoulders a serious mission. It seems that he was also a great athlete in the water sport blitzball."
Jecht (Japanese: ジェクト,Jekuto) is a Rank S Yo-kai of the Tough Tribe. He is a character from the Final Fantasy series, appearing as an antagonist in Final Fantasy X.
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, a metal gauntlet covering his left arm and is barefoot. His outfit appears to be a Zanarkand Abes jumper, similar to Tidus' 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.
