Design a character named Axel "The Juggernaut" Kade, a former heavyweight boxing champion turned underground fighter. He stands 6'4" with a muscular build, rugged features, and piercing blue eyes. His sleeveless black leather vest showcases tattoos, including a roaring lion on his right arm. He wears dark cargo shorts, fingerless black and red boxing gloves, and sturdy combat boots. Add a buzz cut, a scar above his eyebrow, and a gritty, resilient appearance reflecting his tough background.
