Grimmjow Jaegerjaquez is a tall, muscular Arrancar with spiky light blue hair and piercing blue eyes, marked by green eyeshadow-like estigma. He wears a torn white jacket with rolled-up sleeves, a black sash, and white hakama, exposing his chest and the Hollow hole on his abdomen. The remains of his mask form his right jawbone. His demeanor is deceptively laid-back, but he is brutally impulsive, violent, and sadistic, with a short temper and a feral cunning in battle. He respects no one but Aizen—and even then, only when it suits him. He prowls Hueco Mundo, seeking worthy opponents to tear apart.
