20. Grimmjow Jaegerjaquez

Grimmjow Jaegerjaquez (グリムジョー・ジャガージャック, Gurimujō Jagājakku), sometimes romanized as Grimmjow Jeagerjaquesor Grimmjow Jaegerjaques is an Arrancar and the Sexta (6th)Espada in Aizen's affiliated army

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, as well as the red marks on Ikkaku Madarame's eyes

Grimmjow's attire consists of 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 tattoo number (6) is located on his 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

While appearing to be a laid-back individual, this scruffy exterior hides Grimmjow's brutal, impulsive, excessively-violent personality and a lethally-short temper. However, despite his aggression and obvious blood lust in battle, Grimmjow possesses a feral cunning and has a knack for quickly exploiting any opening his opponent reveals. In addition, he is blunt, sarcastic, and quite sadistic, revealing a psychotic grin or laughing maniacally whenever he becomes excited. He is also very rude and quite disrespectful. Grimmjow uses none of the honorifics in the Japanese language, except when addressing Aizen (though he is quick to discard the formality when Aizen is not around), and refers to Orihime as woman in conversation

Grimmjow displays little respect for authority and says whatever is on his mind, regardless of whether or not it is appropriate. This attitude leads to conflicts with Kaname Tōsen, who holds Grimmjow in low regard. He also has conflicts with Ulquiorra Cifer, the 4th Espada, when Ulquiorra interrupts his battles or otherwise clashes with Grimmjow's ideals. Grimmjow confidently believes Ulquiorra's powers to be weaker than his, a point he is eager to prove. He develops an additional grudge against Ichigo Kurosaki for wounding him during their first and second battles, and is eager to return the favor. He intentionally kept the large scar on his chest from their first battle as a reminder of this. Grimmjow is also infuriated by Ichigo's belief that he can defeat him regardless of how badly he is injured, which Grimmjow sees as Ichigo looking down on him

However, he does have some form of a code of honor, as he is unwilling to fight an injured Ichigo, bringing Orihime to heal him beforehand so that their battle will be a fair one, though he also wants to defeat Ichigo when he is at full strength. He also saves Orihime from Loly Aivirrne and Menoly Mallia, who were beating her up, to repay the debt of restoring his arm, though he immediately demands another favor afterwards
