Shinigami Template
Basic Information
Name: Mayuri Kurotsuchi
Age: 25 - 30
True Age: Unknown
Sex: Male
Personality:Mayuri Kurotsuchi is a researcher and personifies the stereotype of the mad scientist. By his early actions during the Ryoka Invasion, he is displayed as one of the most sadistic and cruel Shinigami. He sees everyone and everything not as a living being, but as an object to be researched—including himself. He has little respect or regard for most others, and was even willing to turn his own men (who were not aware of his plans) into living bombs in an attempt to capture Uryū Ishida and Orihime Inoue for experimentation. He also withheld vital information about the Bounts from the other Shinigami in order to capture one as a research subject for himself.
It is known that Mayuri's favorite food is pike fish, and that he does not like onion. One of his free-time activities is reading every character published in Seiretei Communication. He himself publishes a serialization in the journal, titled "Effective Medication for the Brain", which apparently contains detailed instructions on preparation of medicine and their application. Surprisingly, it is highly popular among the readers.
In battle, Mayuri likes to play with his opponent, torturing them little by little until they can hardly stand. This was shown in both the fight with Uryū and his Espada counterpart Szayel. Every time he fights he uses it as an experiment testing himself and his opponent little by little. He also uses it as an oppurtunity to implant microbes or other things in case they get away. Before engaging, though, he will make extensive research on his possible opponents to tilt the chance of winning in his favor. It is seen that, before the Winter War, he is busy reading in the library with a note on the door saying, "Enter and Die." He's shown to be doing this every time before he fights, against both the Bounts and the Espada.

Fears: Not being able to do science?
Character Appearance
Height: 5'8 and a half
Weight: 119lbs
Physical Traits: 
Mayuri's appearance has a very skeletal look to it with a skull-like visage. His face is painted entirely white with the inner portion of his face painted black with the exception of his nose. His eyes are a golden color and he constantly bares his teeth giving the appearance of him constantly smiling. Both his ears are seemingly replaced with stubbed golden cones. His fingernails are blue and, with the exception of the fingernail on his right middle finger, are all short. The one long fingernail is as long as the finger itself.
His whole body, even his face and hands, has been painted black and white. He repaints his make-up every morning, as he always removes it before going to bed.
Clothing: See Pic ^
Accessories: -Remote to Nikubakudan (Flesh Bomb)
-Hojiku-Zai (補肉剤, Flesh-mending Drug): Mayuri has also developed a "regenerative serum," which can regrow limbs upon injection, and looks like some sort of green chemical. He used it to regenerate his arm when he fired it off as a grappling hook, and complained about the side-effects of pain that the serum caused. It can also be used to heal less severe injuries, as seen with Uryū and Renji.
-Data-gathering Bacteria: He also implants opponents that escape from battle with data-gathering bacteria so as to monitor them afterwards, as was the case with Uryū during their fight. This was how he was able to counter Szayel's Voodoo Doll technique -- Using the information gleaned from the bacteria he had implanted within Uryū, Mayuri was able to quickly conceive and carry out an operation to safeguard himself and his lieutenant beforehand.
-Superhuman Drug: Mayuri has manufactured a "superhuman drug" that can slow down a person's perception of time. The drug is kept in a bottle by him, but also inside Nemu's body, which is blue in appearance. It is able to make one second seem like 100 years for the unfortunate victim to whom it is administered. An undiluted dose of the drug causes the senses to speed up trillions of times while the relatively "slow" body fails to keep up, resulting in paralysis; on the other hand, it is implied that a diluted dose of the drug can greatly enhance the user's reaction speed. He even stated that a single droplet would have to be diluted 250,000 times to be suitable for use.
-Anti-Arrancar Mine: After rescuing Uryū from Szayel, he gives Uryū a landmine he designed which is meant to be effective against Arrancar. Once its sensors pick up an Arrancar's reiatsu, it detonates violently. Uryū subsequently used it on the Espada Yammy Llargo, with the effect of critically injuring the Arrancar in his sealed state; the explosion was very powerful.
-Thought Inhibitor Drug: Mayuri concocts a special drug which can stop thought processes from occurring within the brain. Stored in a purple vial, it can be injected into an individual via Mayuri's Zanpakutō. This drug restricts the individual's control over all motor functions, as is the case when Kagerōza Inaba is rendered unable to evade a simple attack from Mayuri. It also can cause the individual's emotions to go out of control. This drug causes the affected individual's eyes to glow with a purple tint.
Fighting Style
General Fighting Style: Uses any information he gathers to come up with a plan before actually fighting someone. He uses his scientific inventions or poisonous gases instead of actually fighting, but has many different modifications on his body which make him able to do things a normal person couldn't, such as extending his arm, or pulling a blade out of his ear. Often he will offer people to become his test subjects instead of dying.
Strengths: Intelligence, Reiatsu/Kido, Offense, Defense
Weaknesses: Strength, Mobility
Zanpakuto & Kidou
Sealed Appearance:
Spirit’s Name: Ashisogi Jizō
Spirit’s Appearance: 
Ashisogi Jizō's spirit takes the form of a baby-sized creature with a similar, though smaller, head to its Bankai state. It has regular arms and legs as opposed to the caterpillar-like body that his Bankai has. It also has wings similar to a butterfly and appears to be capable of flight. There is also a small amount of blue hair on its head and a large halo above its head.
Spirit’s Personality: Ashisogi Jizo is a curious little fella who wanders around seemingly aimlessly. He seems to get startled or scared moderately easy and will often shoot poison gas out as a reflex. He also seems to always want to help, but ends up screwing things up, for example, when Senbonzakura and Zabimaru were trapped in the lab, Ashisogi Jizo finds the remote to let them out, but accidentally pushes his finger right through the remote control, destroying it.
Inner World: Unknown
Kidou: According to Shunsui Kyoraku, Mayuri is one of the most proficient Kidō users in Soul Society.[80] He is capable of releasing a destructive form of Kidō silently from the palm of his hands, blasting holes through walls. (Im not sure what Kido he knows, so any suggestions would be appreciated, he apparently knows a lot though.)
Shikai
Call Out Command: Rip
Appearance:
Ashisogi Jizō's blade glows and transforms into a deformed trident with curved, serpentine blades, the middle blade is straighter and longer than the side blades and appear to ascend from the guard which is shaped like a baby's head with hands clasped in prayer (as Ksitigarbha is depicted), all mounted on his sword's normal hilt which has more ornate spiky protrusions on either side, which resemble golden leaves right below the guard. The baby's mouth secretes a poisonous vapor in this form at various intervals.
Abilities:The weapon works like the venom of a spider bite; when an opponent is stabbed by Ashisogi Jizō, it severs the brain signals controlling the neural impulses for movement in the limbs of the victim, regardless of where they were struck. But unlike regular paralysis, the pain receptors and nerve endings are unaffected by the weapon, so the victim can still feel pain, even in a paralyzed limb. During the Bount arc, it is shown that healing the stab wound does not immediately remove the inflicted paralysis.
Boosts: None Specified
Bankai
New Name: Konjiki Ashisogi Jizō
Appearance: 
The Baby's head on the guard opens its mouth as it produces a giant creature with the body of a caterpillar in a red cape with a grotesque golden baby's head and arms with a silver halo hovering around its head, near the back of the halo are 4 bells, 2 on each side. It emits its own individual, red reiatsu upon release. When in this form his Zanpakutō returns to its sealed state. In this state the creature seems to follows Mayuri's verbal commands.
Abilities: The creature breathes a poisonous derivative of Mayuri's blood which is lethal to anyone who breathes it, aside from Mayuri and Nemu. The poison spreads through such a wide area, and it is almost impossible to avoid it. Konjiki Ashisogi Jizō's poison is very potent, as Szayel Aporro's body started to break down immediately after it was introduced. The poison has an antidote, which Nemu keeps behind her lieutenant's badge, and which Mayuri keeps on his person. Mayuri can change the composition of the poison as well, ensuring that no foolproof antidote can ever be manufactured to cure it, and no immunity is developed against it. Even if the opponent does not breathe, the poison will still enter their body. So far, the only way to be unaffected by the poison is to repel it with a sufficient amount of reiatsu. Anyone within the vicinity of the person repeling the poison will also be unaffected.
Retractable Blades:
Konjiki Ashisogi Jizō can produce numerous blades which can also extend from its chest, allowing it to run through and skewer opponents. This, used simultaneously with its poison makes Konjiki Ashisogi Jizō particularly lethal to anyone that cannot keep a safe distance, which is also difficult due to its immense size. Instead of the blades, it can also apparently devour an opponent after it charges into them, killing them.
Self-Destruct Protocol: Mayuri has also physically modified Konjiki Ashisogi Jizō itself so that it will self-destruct and return to its sealed state if it were to attack him.
Boosts: None Specified
Body Modifications:-Nikushibuki (肉飛沫, "Flesh Splash"): When Mayuri's stabs himself with his Zanpakutō while in its sealed state, it has the ability to transform Mayuri into a liquid form. Doing so doesn't kill him, as it is a last resort technique, but instead simply leaves him unable to attack or be attacked, making it an effective escape tool. He commonly can move around in this form and speak as well. He reforms after a few days but without any of his previous body modifications. This ability is a result of the extensive level experimentation's he has done on himself.
-Jabarakaina (蛇腹腕, "Snake Belly Arm"): His left arm can extend out like a grappling hook. When the arm is attacked it explodes on impact, but with his regenerative serum, this is not a problem (though it does cause him serious pain).
-Hidden Kusarigama: He is able to pull part of his ear out to form a scythe attached to a rope-like ligament for use as a kusarigama. It is easily as sharp as a standard Zanpakutō, and he is quite skilled in its use.
-Nisehada (贋膚, "False Skin"): Another one of Mayuri's abilities likely achieved scientifically is his ability to meld with the color and texture of the environment. It was shown when he was attempting to track the Ryoka in Soul Society. When he reveals himself, the topical camouflage flakes away.
-Organ Replacement Surgery: Most impressively, he has demonstrated the ability to replace functional internal organs with false ones, a feat he performs on himself and his lieutenant to safeguard them from injury. This particular operation is conceived of and carried out in the span of less than an hour.
-Tracking Expert: He expresses the fact that he merely needs a strand of a person's hair to find them. By using a simple chemical process he can discern the location of the person in question using their DNA as a reference.
Toukai
Name: [A greater variation of the bankai name. most likely sounds cooler.]
New Appearance: [You are one with your zanpaktou. Your appearance will most likely mirror a fusion between you and your zanpaktou spirit. What does this amazing new form look like?]
Abilities: [These are your bankai powers at a new height of god-like potential ( without being god mod )]
Boosts: [Being in this state puts your bankai boosts at x4]Back Drop
Background:Soul Society arc:
Mayuri is present at a meeting of the Gotei 13 captains which is convened so that Captain Gin Ichimaru can explain his suspicious actions. Gin, being one of the thirteen captains, should have had no trouble destroying Ichigo and his friends. Gin merely chalks it up to a mistake on his part. Though Mayuri and Kenpachi Zaraki argue over the possibility of him purposefully letting them go, which grows into a argument between the two until they are silenced by Captain-Commander Yamamoto.
During the Ryoka Invasion of Soul Society, Mayuri attempts to search for the Ryoka and use them as test subjects. During the search, Mayuri tries to give a unsanctioned interrogation to Ikkaku Madarame while he is healing in the 4th Division headquarters. Ikkaku refuses to tell him the details of his fight. Disturbed that Ikkaku has nothing to offer, he states that he will need to be punished for his behavior, though Mayuri is promptly stopped by Zaraki (who asks him since when does he have authority over the members of other divisions). Mayuri quickly leaves.
He eventually meets up with Uryū Ishida and Orihime Inoue, whom he tries to capture using his own squad members as bombs. After Mayuri blows up the last of his men, he sees Orihime's Santen Kesshun technique has protected her and Ishida from the blast. Ishida turns his sights on Mayuri, who is now interested in studying Orihime because of her shield, asking if she would like to be his research subject. Mayuri, undeterred by Ishida, continues to add incentives to Orihime to become his subject by issuing offers he normally wouldn't. Mayuri then notices Ishida standing next to him pointing a bow, and tells him that he is pretty fast for a Quincy. Mayuri then states that they are a rare breed and he hasn't seen one alive for many years, but he notes that he has no interest in the Quincy as he finished studying their kind some time ago. When this causes Ishida to question who he is, Mayuri is taken aback at the idea that Ishida and his friends would invade Soul Society without doing their homework; at the very least they should know who the Gotei 13 captains were. Mayuri then gives his name, rank and position. Now realizing what they are up against, Ishida tells Orihime to run for it as he takes on Mayuri. Not about to lose a test subject, Mayuri extends his arm to catch Orihime but it is shot off by one of Ishida's spiritual arrows.
Mayuri is disappointed at the state of his extension arm and detaches it from his body much to Ishida's surprise. He then takes out and uses his Hojiku-Zai which instantly regenerates his arm further surprising Ishida. He remarks that it really doesn't matter if Orihime got away, as he can always track her down, and the sooner he does the sooner he can begin testing. Ishida fires his spiritual arrows at him, but Mayuri dodges the first couple of shots and then uses Shunpo to maneuver to a nearby roof. Mayuri makes note that Ishida has been using Hirenkyaku, an advanced Quincy technique similar to Shunpo. Though Mayuri can use Shunpo to counter the technique, it is tiresome to use and he comments that he can't have Ishida moving all over the place; he resolves to kill him. Mayuri then releases his Shikai and before Ishida can counter with a spirit arrow he is blocked by Mayuri's lieutenant Nemu, causing them both to be injured by Mayuri's attack. Mayuri is livid that Nemu had let go of Ishida after the attack, and hits her as she begs for forgiveness. Mayuri then turns his attention back to Ishida to finish him off.
When Nemu begins to beg for medical help, he becomes enraged and goes over to her and begins to stomp on her for her insolence. When Ishida protests at Mayuri's treatment of his own subordinate, Mayuri claims that she won't die from her injuries as he created her body himself and tells Ishida that she is a construct entirely of his making and therefore his "daughter". He then tells Ishida not to dare try and tell him how to treat her, but Ishida still screams out in protest only to realize that his arm is paralyzed. Mayuri proceeds to tell him what the special ability of his Zanpakutō is, and then stabs Ishida in his arm once again causing him to scream out in pain. Mayuri then tells Nemu to kill him but then realizes that she is paralyzed because of the attack as well and stomps on her again. Ishida screams that he should stop, prompting Mayuri to question whether his philosophy has to do with the Quincy pride that his people were always talking about before they died. Ishida asks what he is talking about and Mayuri details how once he studied the Quincy (though his studies seemingly only included every horrible and cruel treatment possible, more akin to torture) and had ended his study years ago. He sneers that before dying they would always swear on the pride of the Quincy. Ishida listens on in absolute shock as he hears of the butchering of his people. Mayuri then offhandedly reveals that he was the one who orchestrated the death of Uryū's grandfather, Sōken Ishida, and even shows him a photograph of his grandfather.
Ishida is enraged by the truth of his grandfather's death and swears on the pride of the Quincy to kill Mayuri. He then uses an advanced and rare Quincy technique called Ransōtengai, to control his paralyzed body like a puppet. Mayuri notes that he had never actually seen the technique in any of the 2661 Quincy he studied and is surprised that someone so young can use it. Mayuri then takes out his hidden Kusarigama and resolves that since he is starting to find Ishida interesting, he will keep him alive to study as well. But much to Mayuri's surprise, Ishida removes his Sanrei Glove to gain the power to defeat the captain.
Mayuri is utterly surprised as he has never seen this technique before and is unsure of what even happened. He then notices that Ishida is absorbing the surrounding structures, then deduces that since everything in Soul Society is made of Reishi, he is absorbing them and turning them into strength. Mayuri tells Ishida that he has gone far beyond the limits of Humans, but Ishida's only response is the creation of a complex bow construct, from which he fires a spiritual arrow, which Mayuri dodges. To his surprise, Ishida appears above him and shoots him, causing a large explosion. Ishida offers to spare Mayuri if he begs for mercy and never appears in front of him again. He threatens to shoot him with a spiritual arrow three times stronger than the last shot if he does not. The previous arrow grievously injured Mayuri, having destroyed his left arm. Now enraged, he chastises Ishida for his arrogance and declares that he could match his power, and releases his Bankai. Mayuri explains that the poison his Bankai releases would surely kill him, though Ishida states that his arrow will reach Mayuri long before his Bankai's fatal poison can be released. Mayuri sends his creature charging at Ishida, who fires his arrow, splitting it in half and shooting a hole through Mayuri's abdomen. Despite the fatal injuries, Mayuri still lives and much to Ishida's surprise, stabs himself in the throat with his Zanpakutō, allowing him to use its ability to turn himself into liquid so that he could escape, seeping into the cracks of the area.
Later, he hears of Isane Kotetsu's announcement of Aizen's treachery after reforming, but upon being asked by Nemu he refuses to get involved, saying that he is not interested.
Arrancar arc:
Mayuri is seen when Yamamoto calls him alongside the other Gotei 13 captains for an emergency meeting.
Mayuri later appears in Hueco Mundo to assist Renji Abarai and Uryū Ishida in dealing with Szayel Aporro Granz alongside his lieutenant, Nemu.
Szayel attempts to use his Resurrección's voodoo ability and, at first, seemed to have easily beaten Mayuri. Suddenly, Mayuri stands up and taunts Szayel which causes the Espada to continue to destroy organs, but this time it has no effect. As it turns out, Mayuri had taken precautions against this ability by implanting himself with fake organs, having studied the technique beforehand using data from bacteria he implanted within Uryū during their last battle (much to Uryū's annoyance). Szayel then takes Nemu captive, but Mayuri releases his Bankai and devours Szayel with it. Szayel uses the rebirth power of his Resurrección to recreate himself inside Nemu, but in doing so is affected by chemicals contained inside Nemu's body. Mayuri is highly intrigued by this new power, and requests to see what other powers his opponent has. To give him what he asked for, Szayel uses his possession ability to control Mayuri's Bankai, but Mayuri already had countermeasures set in place for just that possibility; his Bankai self destructs, reverting back to its sealed state.
Mayuri, disappointed at Szayel's lack of any further abilities, explains that by recreating himself inside Nemu, Szayel is now dosed with a sense-enhancing chemical that he instantly names a 'superhuman drug', as it were. The drug increases Szayel's senses to the point that his body falls grossly behind and cannot move, paralyzing him as minutes become centuries. Mayuri then berates Szayel for his statement as a scientist that he was the perfect being. He then proceeds to pierce Szayel's hand and continues to slowly thrust his Zanpakutō through to Szayel's heart, wishing him a pleasant eternity, before breaking off the blade as the ultimate torture for Szayel and also as punishment for his Zanpakutō striking at its master.
After searching for Szayel's laboratory throughout the rubble, he realizes that he cannot ask Nemu for help. Musing that she is such a "pain in the ass", he revives Nemu with rather odd and possibly very explicit means and has her dig out Szayel's laboratory, within which are a pair of bodies suspended from the ceiling. After this he continues to to heal Uryū and Renji, the latter being healed first so he could go and help in the other concurrent fights. Once he is finished healing Uryū he gives him an anti-Arrancar mine that he invented.
Fake Karakura Town arc:
When Byakuya Kuchiki tells Ichigo Kurosaki to go back to Karakura Town, Ichigo complains that he could not get back that easily on his own, and that Kisuke Urahara was not there to open the Garganta. Mayuri then suddenly appears behind the group with Nemu pushing a loaded wagon behind him and complains about the fact that Ichigo is constantly fixated on Urahara. He then notes how Ichigo used no honorifics to address him, but muses about the fact that he was better than Byakuya and Kenpachi, whom Ichigo would only address using their given names.
Byakuya takes notice of his unusually lenient mood and asks if it has something to do with the wagon behind him. Mayuri confirms this and tells him that he is in a good mood because, not only has he found some "spoils of war" but at the same place he was also able to analyze the structure of the Garganta. When Ichigo questions his statement, Mayuri begins to rant about what he had learned and orders Nemu to make preparations to send the substitute Shinigami to the Human world. When Ichigo further complains, Mayuri explains to Ichigo that this process was an experiment, and that Ichigo is "Test Subject Number 1" and therefore, he has no right to refuse or to accept.
Retsu Unohana then arrives and says she'll accompany Ichigo back. Mayuri is surprised that she'd offer to be a test subject too, but she smiles and says that she has faith in him and that she believes the experiment will be a success. Besides that, if Mayuri failed to make a Garganta, even after analyzing information found in Hueco Mundo, then Urahara would laugh at him. Mayuri reminds her that he could close the Garganta during the transfer, which she merely acknowledges as being true. Unohana only says that she expects no less. He then opens the Garganta to let both Ichigo and Unohana through. Before Ichigo leaves with Unohana, Ichigo tells Mayuri how he is similar to Kisuke, which infuriates him. After Ichigo leaves, Mayuri comments to himself how fascinating Ichigo is and how he will formulate a plan to torment Ichigo. Byakuya then asks Mayuri why he didn't go to the Human World as well. Mayuri merely replies that there are multiple more interesting specimens in Hueco Mundo and will simply use the Garganta after the war to study the living world more. Byakuya then suggests that Mayuri has faith in Ichigo's abilities to end the war.
Mayuri oversees the checking of the pillars to determine if they are all free of anomalies. As check is completed he initiates the activation of the world shifting bond posts. He is interrupted by one of his subordinates who tells him that he needs to wait as there are Shinigami in the town and a material world transfer without the aid of a senkai gate is dangerous. Mayuri decides that he will give them time and count to ten as his subordinate calls for every Shinigami to get out of town before they are killed. Later, Mayuri begins doing regular research in Hueco Mundo.
