Zommari is a tall, muscular, dark-skinned Arrancar with noticeably large lips. Both his Hollow hole and Espada tattoo are hidden from view, 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 the necklace may also be a 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. His Hollow hole is located at his right nipple.
Zommari has a calm, contemplative personality and rarely spoke prior to his confrontation with Captain 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 Sosuke Aizen, shouting praises to him just before dying.
Beneath this composed exterior, however, he hides a considerable loathing for the Soul Reapers, believing them to be arrogant for hunting down and killing Hollows just because the Soul Reapers consider them to be evil. However, he believes that Hollows can eat Humans without any consequences, a hypocritical statement.
One of Zommari's most prominent traits is his arrogance. Despite his level-headed composure, he is an overzealous individual who treated Byakuya as though he were an equal, but consistently underestimates 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.
Sonído Master: Like all Arrancar, Zommari has standard Hollow powers. However, he holds the self-proclaimed title for the fastest Sonído among all Arrancar, including the Espada. While unproven, his speed is shown to be great enough to keep up with Captain Byakuya Kuchiki, one of the most skilled Shunpo masters in Soul Society, for a period of time, and even force him to use some high-level Shunpo techniques.
- Gemelos Sonído (Twins Sound Ceremondy): He states that increasing his steps even a little will result in quasi-clones. He likens it to a game of magic tricks. The trick is used in order to surprise the opponent. He further explains that the technique is not limited to only two clones; the number of clones produced through Gemelos Sonído can grow to a maximum of five. He uses this technique for diversion, substitution and multi-directional attacks. These "speed-clones" generated by his intense Sonído are so realistic that they have even shown the ability to bleed after getting attacked.
Expert Swordsman Specialist: Though he mainly relies of Sonido, Zommari is in fact a gifted swordsman, able to clash with Byakuya, one of the most powerful swordsman in all of the Soul Society.
Great Spiritual Power: As the Septimo Espada, he contains enough spiritual power to be above most non-Espada Arrancar. His Reiatsu is pink.
Brujeria (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 and has a pink handle.
- Resurrección: The release command for Brujería is "Subside". Zommari levitates his Zanpakuto in front of him horizontally, then clasps 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 an 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 Reiryoku. 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 which somewhat resemble his own face. 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 originating from his eyes. Another five triangular markings appear under his mouth, forming what looks like a beard. The total number of eyes covering his body add up to 50 (including the two on his face), as Byakuya pointed out. 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.
Resurreccion Special Ability Amor (Love): Using the eyes on his body, Zommari can take control of one object per eye; in his own words, "Stealing the sovereignty of whatever it sees". He usually gestures with his hands while doing this. It is initiated when Zommari fixes the gaze of one or more of his numerous eyes on specific target(s). The pupil(s) will widen and the eye(s) itself will glow purple due to his Reiatsu. When Zommari takes control of an object, a sun-shaped tattoo will appear on said object, giving Zommari full control over the object. If targeted on an opponent's limbs, it removes the brain's control from that limb, allowing him to control his opponents' movements or inflict self-harm. In regard to his eyes, each one of them is able to take control of a single separate target. By targeting the head of an individual, Zommari can take control of that person's entire body. This ability is Kido-like in nature, as correctly deduced by Byakuya Kuchiki, and thus, can be countered through similar means, such as blocking Zommari's gaze with the Bakudo 81: Danku.
