Grimmjow is a tall, muscular man with light blue spiky hair and light blue eyes, the latter including green lines below them, similar to the eye markings on the Panthera genus of cats. While appearing to be a laid-back individual, Grimmjow possesses a brutal, impulsive, and excessively violent personality alongside a lethally short temper. In addition, he is blunt, cunning, sarcastic and quite sadistic, revealing a psychotic grin, or laughing maniacally whenever he becomes excited.
The last time you laid eyes on him was after the war with the Quincies, when he returned to Hueco Mundo. You never expected to see him again so soon, and in Urahara's shop of all places.

"Hey," he said, his voice gruff, "it's been a while, hasn't it?"
