Szayel Aporro Granz

Szayel Aporro Granz is an average-sized arrancar with shoulder-length pink hair and reddish-orange eyes. He is Yylfordt Granz's younger brother, although Szayel is much stronger. The remains of his hollow mask take the form of rectangular-framed glasses that give him a scholarly appearance. His arrancar outfit is slightly different from others in that he wears a shorter hakama that exposes a type of sock covering his shins. His shirt is somewhat different from other arrancar as well, as most arrancar have some form of jacket instead. The sleeves are unnecessarily long, covering the majority of his hand, and the shirt has extra seams on the chest area. In his later appearance he also dons a cape.

Szayel is the scientist of the Espada, developing various spiritual equipment for use by the arrancar. Using various methods, one of which involves implanting a subject with rokureichū (a data-gathering device), he is able to analyze the spiritual power of an opponent through those that person has defeated. He is also adept at creating devices that can manipulate and suppress spiritual power, as evidenced in his battle with Renji Abarai. Much like Mayuri Kurotsuchi, he is quite sadistic and seems to view others as little more than research material. However, he is mockingly considerate enough to quiet his followers and remain quiet himself so his opponent can say something.[5] Szayel also openly expresses his disdain of beings who aren't hollows, viewing them as inferior. This racism is also an ulterior motive for his allegiance to Aizen as he hopes Aizen will do away with the non-hollows once he becomes the king of Soul Society. Szayel, however, has shown signs of fear and aggravation with taking damage in battle, actually having to fight, or having his plans fall apart as shown when he first started fighting Ishida or after realizing his abilities were useless on Mayuri Kurotsuchi.

Szayel sometimes acts without Aizen's approval. Although Szayel is very polite to Aizen, later gestures he makes when his back is turned make it appear that he resents him. Like the rest of the Espada, he possesses numerous Fracción, though his are hollows he personally modified and had made into arrancar by Aizen.[6] Two of his notable subordinates are Lumina and Verona, both of whom are round arrancar with bare feet and sparse hair, though Lumina was casually eaten to heal her master. Szayel seems to show the same lack of care for his creations as Mayuri, using them as fodder in battle. When Verona speaks up against this after Lumina is devoured, Szayel quiets her by saying he'd just "make a new one" later.
