Shaz Domino/Expanded Universe

is a Quincy and a member of the Wandenreich's Sternritter with the designation "ϛ" - "Stigma".

Appearance
Shaz is a slender man with blonde hair shaved into 5 parts. He has a number of markings similar to leopard spots on the right side of his face and wears full-framed glasses. His attire is the orders signature hooded-cloak, a variation of the Sternritter's typical white uniform with several buttons along his cuffs and pants, and coattails underneath a yellow leopard print vest.

Personality
Shaz is somewhat arrogant due to his undying nature: he views defeating a captain of the Gotei 13 as merely a way to make himself look good, and considers his unique power to be greater than Gremmy Thoumeaux's The Visionary. He desires to prove that he is more than a byproduct of Gremmy's imagination, and so seeks to create another Hōgyoku and become a Hollowfied Quincy. Shaz is very loyal and grateful to Yhwach for having accepted him into the Sternritter, going so far as to attack the SRDI alongside PePe Waccabrada as a way of repaying his debt to him. He is also scornful of those who betray their comrades, as proven when he insulted and killed a member of Central 46 who pointed out the head librarian to him in an attempt to save his own life.

History
Shaz was originally created by Gremmy Thoumeaux and was nothing more than an imaginary creation like Guenael Lee. However, as he kept repairing his body with The Viability, Shaz eventually replaced every part of his imaginary body with real parts formed from Reishi, and so was able to escape from Gremmy's control. With Gremmy having left Shaz's fate up to him due to lack of interest, Yhwach granted Shaz the Greek letter "Stigma: ϛ" and welcomed him as a Sternritter.

After escaping Ichigo Kurosaki's attack, Shaz fled the SRDI out of concern that he would be sealed away by the researchers if he stayed there to heal himself.

During the Wandenreich's second invasion of the Seireitei, Shaz, seeking information on how to create another Hōgyoku so he can become a Hollowfied Quincy, attacks the Central 46 and wipes out their guards, whom he was disappointed to learn were not even members of the Gotei 13. After killing some of the elderly members of the Central 46 and injuring many others, Shaz finds the head librarian and prepares to cut off her legs so he can carry her to the seal placed on the materials covering the Hōgyoku and have her undo it, but is interrupted by Izuru Kira, who cuts off his arm. After regenerating his arm, Shaz dodges a chunk of rubble thrown by Izuru before being blasted into the Central 46's living quarters by '''Hadō #58. Tenran'''. Assuming Izuru is a captain due to his power, Shaz throws multiple daggers at him, only to be surprised when they are deflected and become much heavier than before. Shaz deduces that this is the power of Wabisuke and believes that he will win as long as he fights at a distance, but is forced to evade multiple '''Hadō #31. Shakkahō''' fireballs before reflecting the last one with another Reishi dagger.

However, Shaz is caught off-guard when Izuru appears directly in front of him, having hid within the smoke in order to get close, and desperately tries to avoid being cut. When Izuru uses '''Hadō #58. Tenran''' again, Shaz loses sight of him and has his arm slashed by Izuru, who attacks him from above. Though Shaz manages to protect his arm with Blut Vene, he knows that subsequent strikes will simply make it heavier, so he cuts off his own arm, surprising Izuru. With his arm already reforming, Shaz kicks Wabisuke away and prepares to kill Izuru, but is suddenly pierced by countless pieces of rubble, which he realizes Izuru had cut with Wabisuke after blowing them into the air with his second '''Hadō #58. Tenran'''. Shaz is forced to the floor and is stabbed a few times by Izuru, causing his body to break under its own weight, as his body continues to regenerate by absorbing Reishi from the ground underneath him, making Shaz sink deeper and deeper in the ground. Swearing revenge on Izuru and all other Shinigami, Shaz continues to sink into the ground until his voice can no longer be heard.

Powers & Abilities

 * Any damage inflicted on Shaz's body is repaired by absorbing Reishi from his surroundings, up to and including replacing lost limbs, making him completely undying. With this ability, Shaz managed to escape the control of his creator, Gremmy Thoumeaux, by replacing each part of his imagined body with real parts formed from Reishi. This ability was originally known as, but Yhwach renamed it to Stigma to match the Greek letter that he designated Shaz with.

Reishi Manipulation: As a Quincy he primarily absorbs spiritual energy from the atmosphere, and combines it with his own spiritual energy to form weapons. He has an easier time collecting this energy in environments with higher concentrations of Reishi such as in Soul Society or Hueco Mundo.


 * An advanced Quincy technique which grants one inhuman offensive and defensive capabilities, generated by making Reishi flow into the user's blood vessels. The independent forms for attack and defense cannot be employed simultaneously.


 * With his Blut Vene active and concentrated in his arm, Shaz can withstand a strike from Izuru Kira's Wabisuke without injury.

Stigma
Uncontrollable Healing: Shaz's regeneration occurs automatically and cannot be halted, even by him; therefore, if he is in a situation where his absorption of Reishi from his surroundings is somehow trapping him, he will not be able to escape unless his entire body is destroyed so he can reform it elsewhere.

Trivia

 * Stigma (ϛ) is a ligature of the Greek letters sigma (Σ) and tau (Τ), used in Greek writing between the Middle Ages and the 19th century (to represent the sound /st/).
 * The English word stigma, from Latin stigma and Ancient Greek στίγμα (stígma, "mark, spot, brand"), can generally refer to a mark of infamy/disgrace (i.e. social stigma) or to a physical mark: e.g. a birthmark, scar, or spot characteristic of a defect/disease.
 * In Catholicism (chiefly in the plural stigmata), the term refers to bodily marks/pains resembling the wounds of a crucified Jesus, sometimes accompanying religious ecstasy; the Japanese translation is.
 * The abovesaid concept of a "stigma" is referenced by Shaz's ability, specifically how the Quincy perceive his undying existence as a "holy scar" on the world.
