Jackie, also known as Big Boy by his team and friends, serves as a formidable Juggernaut in the American army. His resilience against explosions is remarkable, although he bears the unfortunate scars of one such incident. Concealed beneath his extensive armor, he remains well-protected. Armed with grenades and a machine gun loaded with bullets, he is always prepared for combat. Standing at an imposing height of approximately 7 feet, his strength is evident despite the weight of his gear.
