Zommari is a tall, muscular, dark-skinned Arrancar with slightly larger lips than the others. Both his Hollow hole and Espada tattoo are not visible, but the remnants of his Hollow mask consist of a row of bony spikes along the crest of his head, forming something similar to a Mohawk hairstyle along with a pair of skull-shaped earrings and a thick bony necklace, however it is uncertain if this necklace may also be part of his hollow remains. This gives him somewhat of a witch doctor appearance. He is also bald and has golden yellow eyes. Zommari's uniform consists of a long mandarin-style Arrancar jacket with a small opening at his chest area. He wears a default hakama like all other Arrancar, although his sandals resemble traditional martial arts training shoes. Zommari has three triangle-shaped tattoos on his chin. He also has four lines running down from his forehead directly above his eyes that end with dots appearing as exclamation points. These are on both sides of his head, giving him a total of eight lines.
Zommari displays a calm, contemplative personality, and rarely spoke prior to his confrontation with Byakuya Kuchiki. Apparently, Zommari likes to keep himself in a calm and peaceful state of mind, due to him usually residing in a special meditation room, where he awaits his orders. He has a great deal of respect for Sōsuke Aizen, shown by his shouting of praises to him just before dying.
Beneath this composed exterior, however, he hides a considerable loathing for the Shinigami, believing them to be arrogant for hunting down and killing Hollows just because the Shinigami consider them to be evil. However, he believes that Hollows can eat Humans without any consequences, making him seem hypocritical.
One of the biggest traits that led to Zommari's downfall was his arrogance. Despite his level-headed composure, he is an overzealous individual who treated Byakuya as though he were an equal, but consistently underestimated his opponent's abilities. Whenever Zommari would take control of his battle with Byakuya, he would remain calm and assertive in his supposed superiority, but when caught in a helpless situation, he would show signs of despair and become even more intense in his anger towards his opponent. His insistence on proving his superiority without actually testing his opponent's full power, or striking him directly when he was fully capable of doing so, proved to be his eventual undoing.
Brujería (Spanish for "Witchcraft", Japanese for "Sangha of the Bewitching Eyes"). It resembles a normal katana with the exception of the guard, which appears as a thick disk with spikes around the rim.
The release command for Brujería is "Suppress" (鎮まれ, shizumare; Viz: "Subside"). Zommari levitates his Zanpakutō in front of him horizontally, then claps his hands together. He then twists his head until it's perpendicular to the rest of his body and takes a bracing stance. When he says the release command, his sword bends into the shape of a edged spiral. Once in the shape, a thick white smoke emits from the corners of the spiral and covers his body transforming into a thick, white, foamy liquid that mixes with his Spirit Power. In its release, Brujería covers Zommari's entire body with fifty open eyes, and his legs (along with his lower body) are replaced by a pink pumpkin-like (or sea urchin-like) structure surrounded by cyclopean faces that somewhat resemble his own face (In the manga, the entire pumpkin like structure is colored red and the extra eyes are yellow). His legs disappear, and he now floats in place. His neck is covered in a skull-shaped neck brace with an open eye in the front. Black markings also appear on his face, in the form of two downward triangles starting from his eyes. Another five triangular marking appears under his mouth forming what looks like a beard. The eyes cover Zommari's entire body except for his head. However he later reveals eight more hidden eyes above his normal two on his forehead area. Whether or not he is capable of using Sonído in this form is never shown in the manga, though he briefly uses Sonído in the anime as he curses Byakuya.
