Grimmjow Jeagerjaques

Grimmjow has light blue hair and eyes, which have blue/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 and a black sash; his white jacket is ragged with an upturned collar. The inner lining is black, the sleeves are rolled up, and Grimmjow wears it open, leaving his chest revealed. The remains of his hollow mask consist of the right jawbone, and his hollow hole has moved to his abdomen.

Grimmjow appears to be a laid back and irreverent individual, but this scruffy appearance hides an impulsive, excessively violent personality and a lethally short temper. Grimmjow is blunt, rude, and quite sadistic, revealing an insane grin in battle, much like Kenpachi Zaraki. Grimmjow has 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 the same low regard as he did Zaraki. He also has conflicts with Ulquiorra Schiffer, the 4th Espada, usually because Ulquiorra interrupts his fights or doesn't act on his own impulses. He has also developed a grudge against Ichigo Kurosaki for wounding him during their first and second fights, and is eager to return the favor. He purposefully kept the large scar on his chest from their first battle as a reminder of this.

Grimmjow is the sixth Espada in Sōsuke Aizen's army of arrancar, meaning he is ranked sixth in terms of strength. Grimmjow was the first character to be revealed as an Espada in the series. A crooked number 6 is tattooed on his back just above and to the right of his hollow hole. Aizen personally marks the Espada, the ten most powerful of his arrancar, with such tattoos as visible marks of their rank and ability. After Kaname Tōsen cuts off and burns his arm, Grimmjow is demoted and quickly replaced by Luppi, much to his annoyance. After Orihime Inoue heals his arm, he kills Luppi to regain his rank, impaling him on his newly restored arm and then vaporizing Luppi's torso with a cero blast.

Grimmjow is a very rude and disrespectful character. He uses none of the honorifics in the Japanese language, except when addressing Aizen, and refers to Orihime as woman in conversation. However, he does appear to have some sort of a code of honor, as he is unwilling to fight an injured Ichigo, bringing Orihime to heal him beforehand so their battle will be a fair one. He also saves Orihime from two female arrancar beating her to repay the debt of restoring his arm, though he immediately wants another favor in return.

Grimmjow's character design draws heavily from Gamma Akutabi, a character in Tite Kubo's earlier manga, Zombie Powder. Gamma has prosthetics in the same area where Grimmjow has his remnant hollow mask. They both share a missing arm, although both on different sides. Grimmjow's released form makes the resemblance even more apparent with similar long spiky hair. The two have also been identically posed for volume covers.
