Szayel Aporro Granz (Zaeruaporo Gurantsu), sometimes romanized as Szayelaporro Grantz, is an Arrancar in Sosuke Aizen's army and the octava (8th) Espada. He is Yylfordt Granz's younger brother.

Szayel has shoulder-length pink hair and amber eyes. The remains of his Hollow mask take the form of rectangular-framed glasses, giving him a scholarly appearance. The placement of his Hollow hole and Espada number tattoo are both unknown. Even after having the entire upper half of his body exposed, no hole or number tattoo can be seen. His clothes differ from the original Arrancar uniform. Instead of a normal jacket, Szayel wears a long shirt that covers his entire torso up to the top of his neck.

He has three stripes on his uniform, each starting at his collar with one running to the left side of his chest , one to the right side of his chest, and one down the middle. He wears the regular pants with a slight length taken away. He also wears white gloves. His face is the only part of his body that is exposed in this uniform. After he changes his clothes, he sports a cape-like garment. When he was demoted from the Espada sometime in the past, his appearance was slightly different. His hair was messier and all three lines on his uniform dropped to his right hip, instead of to the left, right and middle.

Szayel is a meticulous intellectual and the scientist of the Espada. Unlike all the other Espada, Szayel is highly narcissistic, extremely flamboyant, and tends to make lewd, disturbing comments about his opponents. Szayel is quite sadistic and views others as little more than research material. He thinks poorly of non-Hollows, and hopes that Aizen will someday wipe all non-Hollows out of existence.

He also thinks of himself as an actor, treating his battles like theatrical performances, especially when toying with his victims.  He seems to have had a less-than-positive relationship with his older brother, Yylfordt. While he did try to heal him after his battle with Renji, he refers to Yylfordt's death as Renji merely breaking a box of parasites, and says that he wouldn't be so childish as to be upset over that. He boasts that he is a "perfect being," since he is capable of reproducing himself in another person's body, and thus, views himself as immortal.

Sometime in the past, Szayel helped Nnoitra Jiruga perform a sneak attack on Nelliel Tu Odelschwanck. In order to help him do this, Szayel used a device that created an illusion of Nnoitra which distracted Nel Tu attention. By exploiting the opportunity, Nnoitra attacked Nel Tu and she was hit from behind, causing a wound to her head and her mask to break on the front left side. The attack scarred her forehead and left her unconscious. He took her unconscious body and stated that she would probably call this an act of a beast but it didn't matter any to him. He was approached from behind by Szayel who asked if there was anything else he could help him with, to which Nnoitra responded that his job was already over.

Szayel asked him if he needed to be so cold as they worked as partners, for that he should at least be allowed to admire their end. Nnoitra detailed that he doesn't remember being his partner and that they just happened to have the same motives. Nnoitra threw Nelliel off the side of Las Noches so that he could increase his power by the time she returned. Nnoitra told Szayel they were going, but Szayel told him that he would appreciate it if he lost the presumptuous tone. Nnoitra reminded him that he wasn't an Espada anymore.

Szayel stated that if not for the equipment that he prepared Nnoitra wouldn't even have had the chance to attack Nelliel, and then asked if he should really be speaking to him that way. Nnoitra looked over the side of Las Noches at Nelliel and her Fraccion's prone bodies and was surprised as she reverted into a child. Szayel noted that he had not anticipated this and he had never seen anything like it before. He deduced that her reiatsu was leaking out of the wound on her mask, and her spiritual body shrank as a result.
