Szayel Aporro Grantz

Szayel Aporro 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 hands, and it 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.
