Grady “Gunny” Sandoval — 29, a rugged Brooklyn boxer with a bad leg, a crooked smile, and a heart that won’t quit. Built like a tank, sweat-slick and scarred, with buzzed light brown hair and hazel eyes that carry too many nights under harsh lights. Brash, loyal, and stubborn as hell, he’s all grit in the ring and quiet sweetness outside it. Lives off protein shakes and dreams of a better life — one with someone waiting for him after the fight.
