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, which is fitting, given the name of his Zanpakutou and his Adjuchas form.
Grimmjow wears a white hakama, a black sash and a ragged white jacket with an upturned collar. The inner lining of his jacket is black, the sleeves are rolled up, and Grimmjow wears it open, leaving his muscular chest exposed. The remains of his Hollow mask consist of the right jawbone, and his Hollow hole is located on his abdomen. His Espada tattoo is located on his lower back, near the right side of his Hollow hole. Grimmjow also sports a large scar across his torso, gained from his first battle with Ichigo Kurosaki.
Befitting of his relation with panthers, Grimmjow is a feral, brutal Arrancar who loves violence and bloodshed, though he isn't quite as obsessed with it as Nnoitra Jiruga. He is also very laid-back and disrespectful, as he rarely refers to anyone with proper honorifics with the exception of Sosuke Aizen--though he will quickly drop any such honorifics when Aizen is not around.
Grimmjow is also rather arrogant, and will happily pick a fight with anybody, even those who could easily defeat him. He also shares many characteristics with Ichigo Kurosaki in that he is foul-mouthed, impatient, sarcastic, blunt, witty, hot-headed, and impulsive. Despite his brutal and arrogant nature, Grimmjow is far from stupid, though his ego and bloodlust will, more often than not, overcome any common sense he might have. Also, unlike Nnoitra, Grimmjow--while willing to exploit openings in his opponent's guard--does possess a sense of honor and fair-play, and seems to dislike skulduggery.
Grimmjow was initially a panther-like Adjuchas. At some point, he came upon another group of Adjuchas (and one Gillian, who were staying together in order to survive. Grimmjow assumed leadership of the group, and they began attacking other Hollows as a pack in the hopes of becoming more powerful, speciically to become Vasto Lorde. Unfortunately, no matter how many Hollows they successfully brougt down and ate, they were unable to evolve.
Grimmjow grew impatient and considered killing the rest of the group, though for some reason, he changed his mind. He declared that he would one day become a "king", but of what was not yet known to the others, and may very well have been unknown to him. Regardless, Grimmjow became determined to get stronger, but he never did.
At some point, the group was approached by Sosuke Aizen, who turned them into Arrancar and made them his servants. Grimmjow eventually rose to the position of Sexta (Sixth) Espada, while the others became his subordinates, or Fraccion.
