NameSergei Altair Zarkonheinz
AgeUnknown
GenderMale
Natural or ArtificialNatural
Appearance 
It is unknown where his hollow mask remains, hole, or tatoo is. He is around 8'0, making him the tallest known Espada.
PersonalitySergei is cold, callous, unsociable, and enjoys sacrificing people for his own gain. He is normally seen without removing the guard of his helmet and refuses to reveal his face. He is arrogant and thinks of himself as the only person who is strong enough to challenge the leader of the Espada. He has a temper that is easy to set off. He has a seal on him that limits his anger, but it is easy to break with enough pure power. When it is broken, he is extremely dangerous and will attack nearly anything and everything around him.
AbilitiesSonído Master: Sergei's skill in Sonído is so great that it seems as though he possesses a form of teleportation as he moves in the blink of an eye, simply "appearing" solidly instead of shimmering for a second like other Sonído users.
Master Swordsmanship Specialist: Sergei has demonstrated tremendous skill in swordsmanship.
Garganta: Garganta is how Arrancar move to and from Hueco Mundo. Arturo has the ability to use the technique. It literally tears open the dimensional fabric separating the worlds, revealing a tunnel of whirling, torrential energy that must be focused and solidified to create a discernible pathway.
Immense Spiritual Power: As being the Cero Espada, he possesses tremendous spiritual power. Sergei is forbidden to release his Zanpakutō inside of Las Noches, as such a release could destroy the fortress. His spiritual energy is black, purple, and red.
Keen Intellect: In addition to his remarkable combat prowess, Sergei is also gifted with great insight and understanding to situations at hand. With his calm and collected nature, Sergei has can be highly perceptive and analytical, allowing him to easily deduce the basic idea of his opponent's skills to figure out its strengths and weakness.
Cero: Sergei has been shown using Cero from his fingers with very destructive power. His Cero can be charged and fired relatively fast and is a black, purple, and red color instead of just a red, mimicking his reitsu.
Enhanced Vision: Sergei's eyes have the power to see through any illusion or deception; to basically see and understand anything in his sight. He even goes as far as saying he can only not see what doesn't exist.
Enhanced Pesquisa: The Arrancar ability to sense spiritual energy. While any Arrancar can learn it, Sergei has shown impressive skill with it. From a single glance at his opponent, Sergei can immediately determine how powerful his opponent is. He is also able to comprehend the flow and concentration of the person's energy.
Gran Rey Cero: As an Espada, he is able to use this Espada-exclusive Cero variant, which produces a larger and more powerful version of the normal Cero, enough potentially to cause great damage to Las Noches itself. It seems that he must slice the inside of his right hand in order to fire it.
Bala: The technique hardens the user's spiritual pressure and fires it like a bullet from their fist. Sergei has a Bala that is colored exactly like his Cero. He fires it from his right hand.
Cero Oscuras: (黒虚閃, セロ・オスキュラス, sero osukyurasu; Japanese for "black hollow flash", Spanish for "Dark Zero"): It is a black Cero. Like many other Espada related techniques, this technique can only be used by Espada in their released states. It is also possible that it is only usable in the Espada's released state, meaning it is only forbidden to be used by Espada of at least Cuarta (4, 3, 2, and 1). This however, would not include the Espada lower than Cuatra from simultaneously releasing their Zanpakutō and performing Cero Oscuras.
Mi Derecho Aguja Fallo: (My Right Hand's Judgement) Sergei picks up an opponent with his massive right hand by their head. He fires a cero-like attack from the palm of his hand. If they survive, he deems them worthy to see his Resurrección.
Unnamed Absorbtion Ability: Sergei can absorb a wounded opponent via the "mouth" in his chest. He can only absorb one high-level opponent at a time, but he has been shown to absorb multiple Menos and Gillians at a time.
Enhanced Hierro: In his pre- and post-Resurrección form, Sergei has proven himself to be highly resistant to both pain and injury
Sealed Zanpakuto
It is extremely heavy, yet Sergei wields it with great ease. It is stored in an area of subspace and Sergei can summon it whenever he needs to. It is about 5'5" long and about two feet across. It weighs about 300-500 lbs.
ReleaseMelt their flesh, Averno Amante(Hell's Flames).
Resurrección
Sergei has confirmed this is not how he looks under his mask, he says his Resurrección form is just a "beautified facade. Under it is pure terror and fear."
Turchino Fiamma Fierezza (Blue Flame of Pride): This fire is more like electricty. It is smaller and is much faster than his other single fire attack. It is also more controlled and can act like a whip.
Vermiglio Sparare Vanto (Red Blaze of Glory): His more powerful single fire attack. He can fire large bursts of fire from the one attack, or create a massive single burst.
Dorado Reventar Muerte (Gold Burst of Death): His most powerful attack. He puts his hands together and a massive, almost triple the height of Sergei, ball of gold-colored fire. It is semi-controlled, as Sergei can change the course of the blast somewhat. It can also take the form of a phoenix.
Reiatsu Swords: Sergei is able to summon spiritual energy swords from the area around him, which vaguely resemble Hyourinmaru.
Verdadero Cero: Spanish for "True Zero". Sergei fires a cero from his mouth, all of his fingers. It has the speed of a Bala with nearly the power of a Gran Rey Cero.
Segunda Etapa: Like Ulquiorra, Sergei has a second Ressureccion.
Appearance:
His entire body other than his forearms, hands, shins, and feet is made completely of pure fire
Abilities:
He gains an enhanced version of all of his first Resurrección's attacks as well as being able to melt almost anything.
Unnamed Ability 1: As the temperature of the area around him increases, the larger he grows. He does not shrink if the temperature decreases, but rather hardens. When he is completely hardened, he will return to his first form.
Unnamed Ability 2: Sergei can create large phoenix-shaped attacks that home in on an enemy.
Enhanced Reiatsu Swords: Sergei is able to summon spiritual energy swords from the area around him, this time they look appear like his unreleased Zweihänder.
Enhanced Verdadero Cero: Spanish for "True Zero". Sergei fires a cero from his mouth, all of his fingers. It has twice the speed of a Bala with nearly the power of a Cero Oscuras.
HistoryNot much is known about Sergei's life in the world of the living, in fact,
nothing is known. It is rumored Sergei is not the soul of one person, but many that formed together into one being. As a hollow, he stayed in the depths of the Menos Forest, killing many many menos and Gillians. As he progressed through the first stage of hollows, he became more powerful and more feared. He was known to eat anyone and anything he saw. it is said when he advanced into his Adjuchas stage that is when the fire-related powers appeared. It is rumored that Sergei once melted all of the Menos Forest and that is what made it so desolate today. About five hundred or so years ago, Sergei became a Vasto-Lordes-class Hollow. It is unknown how he became of this power, or where. Over time, he became longing for more power, but he was at the top of the tier...
for a hollow. He instead heard of a hollow that ripped his mask off to become even stronger. His name was Arturo Pladeato. Seeking the same power, Sergei sought out Arturo. After a duel, Arturo noted that Sergei was much stronger than he was and ripped his mask off. With this newfound power, Sergei roamed Hueco Mundo, killing the Adjuchas and Menos.
As he gained more power, he was able to release his Zanpakutou. He did not like how this made him look, as it did not reflect any portion of him. He found Arturo once again, this time he hungered. Before Arturo could even unsheath his Zanpakutou, Sergei had sliced his right arm off. Sergei then proceeded to absorb him. With Arturo's power inside of him, Sergei grew stronger, and thus he was able to attain the second level of power for a Resurrección...
The Segunda Etapa. When he heard of Aizen, he wanted to challenge him, but something told him to get greater power he needed to wait. And so he did, killing more hollows until he heard of a new ruler of Hueco Mundo. Upon meeting him, he served under this person until Sergei literally ate him with his chest-mouth. With that, he took the mantle of the "God of Hueco Mundo" and took the mantle of Cero Espada. He is the current leader of Hueco Mundo, and the strongest person in that realm.
