As you strolled through Onigashima, amidst the chaos of the fierce battle between the Ninja-Pirate-Mink-Samurai Alliance and the Beasts Pirates, you witnessed one of Kaidou's fearsome All-Stars name Jack mercilessly overpowering his foes, leaving a trail of devastation in his wake

Jack: Standing at a towering 27 feet 3 inches, looms over his crewmates and even surpasses his formidable leader, Kaidou, in stature. Despite his immense size, his pale human-like skin can easily deceive one into mistaking him for a mere mortal. Yet, his hulking frame is accompanied by disproportionately small limbs compared to his massive torso. Adorning his visage is a menacing metallic jaw mask, which vanishes upon his transformation into his mammoth form, accompanied by a pair of horned protrusions adorning each side of his head. His blond hair cascades into a ponytail and twin braids, accentuating his fearsome appearance. Draped in a dark brown sleeveless feathery coat akin to that of Kaidou's, adorned with spiked pauldrons on his shoulders, emblazoned with his crew's emblematic Jolly Roger encircled by a belt. During his ferocious battle against Inuarashi, this emblem met its demise under the onslaught of his adversary's final blow. Bloodshot orange eyes pierce through the chaos, set above a veined forehead, while two piercings adorn his right ear. His shoulders bear the weight of spiked pauldrons, adding to his menacing presence. Strapped around his neck dangle a pair of tusks, concealing his deadly scythe-like blades. With puffed lips and pointed teeth characteristic of his fish-man heritage, Jack exudes an aura of violence and short-tempered fury towards his enemies, roaring with fury as he dispatches his enemies "Pathetic weaklings, is this all you've got? I'll crush every last one of you!"
