Only a few of these are technically new as I've mostly gone back and redrafted ideas I felt could be much improved.
Name: Shikai: Karigetsu, Hunting Moon
User: Kurosaki Karin
Ability: This zanpakuto takes the form of a ji, a Chinese halberd, with a pair of small crescent blades attached to the head and a blue hair-tail where the head is fixed at the shaft. Its design made it efficient for slashing, thrusting, battering, scything and sweeping, giving it a wide range of attack.
Its ability focuses KarinÆs spiritual energy within the halberd which is then propelled forwards in a super-fast thrust. Her form is fused with the soaring lance when the ability is active, turning into a destructive comet that pierces through the target. Whilst the technique possess both speed and power, itÆs impossible to alter its trajectory after it begins which forces it to move in a straight line until the move is complete, making it very predictable.
Its second ability has Karin charge the lance with spiritual energy and then throws it at her opponent. The energy accumulated within the lance causes it to accelerate after being thrown, achieving far greater speeds than would be possible with just throwing power. At the point of impact, all that accumulated energy is released in a destructive blast of energy that blows everything away. Whilst powerful, the technique has the disadvantage of leaving KarinÆs unarmed during it usage though she eventually learns to have the lance transport itself instantly back into her hands.
Name: Shikai: Senrugetsu, Transient Moon
User: Kurosaki Yuzu
Ability: This zanpakuto splits into ten double-edged daggers with identical designs.
Yuzu can choose to wield these daggers in melee, throw them as projectile or have them move through the air through telekinesis. As her experience with the zanpakuto grows, she becomes able to initiate more complicated manoeuvres that allow her to strike her opponent from difficult positions with precise timing.
However the daggerÆs main abilities are two-fold; Yuzu can teleport herself to the location of any one of her daggers and she can teleport her daggers to any location within a certain range. With the first ability she can instantly move out of her opponentÆs line of sight and allow her to attack from an entirely different angle. The second ability allows her to transport her daggers to her opponentÆs blind spot which, when combined with her remote control, greatly increases their range of movement and the lethality of her attacks.
Name: Shikai: Engetsu, Scathing Moon
User: Kurosaki Isshin
Ability: This zanpakuto has no definite form but when it is first released its appearance remains the same as its sealed state.
Its ability allows the zanpakuto to transform into any type of melee weapon that Isshin has seen before or possesses knowledge of including different types of swords, axes, spears, hammers, knife etc. His experience with the zanpakuto makes it so the transformations are instantaneous and he reproduces the ideal shape every time.
But that is only the most basic ability; the true power of this zanpakuto lies in its ability to mimic any zanpakuto that he has seen in their shikai state. This requires him to be within the vicinity of the targetÆs reiatsu for a certain period of time for his zanpakuto to absorb traces of it, allowing him to imitate their physical form and/or utilise any of their abilities. Naturally, these abilities are often inferior to their original and Isshin is limited to a single transformation at a time. Though it has only been tested once in the past, he is only able to mimic the zanpakuto of shinigami, not a hybrid species like the arrancar.
Name: Bankai: Awaisanzen Engetsu, Pale Radiance Scathing Moon
User: Kurosaki Isshin
Ability: Like its shikai, this zanpakuto has no definite for, being both invisible and intangible.
This bankai allows Isshin to manifest any kind of melee weapon he has seen before or possesses knowledge of within a certain range of his own body. He can summon a near-infinite number of weapons that can be copies of a single one or a random assortment of different types. He can hold them or have them levitate in the air around him, making them move according to his will without even needing to touch them.
In addition to these unspecific weapons, Isshin can also manifest any zanpakuto that he has witnessed before and use it as his own weapon. Not only that but he can summon multiple zanpakuto simultaneously and have access to all their abilities instead of being limited to one at a time. Though the power and effectiveness of their abilities remain the same as in shikai, mean he has to focus on using different effects instead of stronger ones. (Warning: This power isn't compliant with Final Getsuga concept)
Name: Bankai: Makazeshini, Demon Wind Death
User: Hisagi Shuuhei
Ability: This bankai takes the form of a pair of windmill shuriken; a boomerang-type projectile with four curved blades protruding from the inner circle. Hisagi is able to manipulate the movements of the shuriken by controlling the air currents, forcing them to spin independently so they are able to saw through targets. He can choose to make it rotate around his wrist for melee combat, allowing him to deflect attacks or slice his opponents.
Its ability allows it to produce tornadoes of black wind from the centre of the shuriken, enabling it to blow targets away and shred them with high speed winds. Hisagi can focus his spiritual energy into the circle to create a sphere of highly compressed wind that is filled with countless microscopic blades of wind. When released, it creates a destructive vortex which is able to cut through anything caught within range on a cellular level.
Name: Bankai: Ijikitanai Hisagomaru, Gluttonous Gourd
User: Yamada Hanataro
Ability: This bankai creates a beige-coloured gourd with a black line spiralling from the base to the tip which Hanatarou holds close to him. The gourd produces a unique suction effect that doesnÆt affect the atmosphere at all but only living organisms within the range of his reiatsu.
For humans and pluses, any and all physical injuries they possess are healed as they are converted into red smoke which is drawn into the gourd. At the same time it draws in their physical fatigue to restore their stamina so they can continue to fight at peak condition. For hollows the gourd produces the opposite effect. It continually drains their physical stamina to gradually increase their fatigue and at the same time, re-opens all the wounds that the hollows have ever been inflicted with.
As the red mist is absorbed, the black line is filled up with a red line to signify how full the gourd has become. Hanatarou is able to convert this energy into destructive force and fire it as a beam of energy akin to a Cero. The more the gourd has been filled, the more powerful the blast and at full strength, there is practically nothing capable of surviving the blow.
Name: Nerv, Nerve
User: Quincy
Ability: This is one of the Quincy body-enhancement techniques that functions independently from Blut. By absorbing reishi and making it flow through their nervous system, the Quincy is able to stimulate their neural synapses.
One version of this is Nerv Sinne, Nerve Sense, which is able to enhance the QuincyÆs sense of touch, taste, smell, hearing and sight. They can choose to enhance one or more these senses depending on their intention which significantly increases their awareness of their surroundings. In fact, Quincy has been using this version unconsciously for generations as they enhance their sense of sight to help their marksmanship. However using this can be hazardous should one or more of their sense by overly stimulated, causing a painful mental feedback.
The second version if Nerv Gang, Nerve Gear, which is able to allow the Quincy to react faster to danger and push their physical process to their limit. They become capable of moving at far greater speeds than normal, striking with greater force and become able to evade attacks that they normally wouldnÆt be able to. Similarly to Blut, these two versions work on different reishi systems which prevent them from being used simultaneously. A master of the technique would be capable of combining this with their Blut to improve their offensive ability or ability to block and evade attacks.
Name: Suika, Hydration
User: N/A
Ability: This is a natural ability which allows the user to liquefy their entire body at will, changing it from solid to liquid or vice versa as they desire. This allows them to avoid receiving damage from physical attacks, infiltrate a structure, drown a target or modify their body parts for suitable situations. ItÆs possible for them to release this water in the form of attacks such as high-pressure jets or bullets which can slice or pierce through most obstacles with ease.
An advanced form of this ability available to the user allows them to enter a gaseous state which transforms them into mist. The mist itself is their body and they become aware of everything within its reach, disguising the userÆs location whilst rendering visibility to zero. As mist the user is unable to cause damage but they can choose to reform their body parts to strike at the enemy whilst they remain unaware.
Though itÆs not often that circumstance permit it, this ability can be taken to further hides when near a large body of water. By merging with said water, the user becomes able to use it as if it were a part of their own body by infusing it with their spiritual energy. Primarily this increases the scale of the userÆs techniques as they are no longer limited by their own body mass but rely on the natural source of water instead.
Name: Kafuka, Overload
User: Kon
Ability: This ability stems from the artificial nature of KonÆs soul and the boosted abilities he was developed with. Due to the mod soul experiment being terminated almost as soon as it was completed, there was very little data on the capabilities of mod souls beyond what they were designed with. None were involved in real combat for any length of time. KonÆs proximity with Kurosaki Ichigo and his friends, as well as being regularly caught up in various conflicts resulted in his abilities evolving beyond what his creators thought possible.
The most basic aspect of this ability and the only one Kon is consciously aware of is his legs becoming as hard and as dense as steel, increasing their strength to provide incredibly leg power. But this only provides a bare hint of his true capabilities and is not limited to his legs.
Overload causes a fundamental charge within KonÆs body, whether human or gigai, which transforms it from flesh and blood into a mechanical humanoid. Appearance-wise, it remains looking like a regular human when not in use but in actuality it becomes more like a machine. KonÆs entire body becomes made of steel, possessing numerous types of weaponry and implements within and its freedom of movement differs greatly from an ordinary human body.
Kon can alter the nature of his vision to produce different types of sight depending on the situation, allowing him to see in the dark, view heat energy, see through physical and spiritual matter, tracking spiritual energy or track high-speed movement.
He is able to remodel his right arm to produce different types of melee weaponry for use in close combat. His left arm can be used to fire projectiles of spiritual energy in the form of bullets or lasers by producing boosters from his palms or fingers or transforming his entire arm into a cannon. His legs are able to produce missiles of spiritual energy which can be fired at the target and explode upon impact. He can produce propulsion from his feet to initiate flight and can also fire either of his arms as projectiles which move according to his will. The quantity and power of these are dependent on the amount of spiritual energy Kon possesses.
The unusual nature of this power lends itself to unsurpassed versatility and adaptability. Depending on KonÆs intentions, itÆs possible that he could alter the armaments within his body to focus in a specific direction such as changing all his weaponry into missiles, allowing him a greater number of option with only that weapon type.
Name: Bankai: Miyagi Benihime, Imperial Palace Crimson Princess
User: Urahara Kisuke
Ability: The construct produced by this bankai is a translucent apparition of a Japanese-style castle that expands outwards from KisukeÆs position to engulf the area. It is composed of crimson energy and is shaped into the basic outline of a castle rather than a complete reconstruction, built in a square shape and multi-tiered. The ghostly aspect of it makes it seem different from a barrier and it is actually easy to penetrate.
But escaping from the castle is another matter altogether. The main ability of this bankai is for the energy that composes it to continually corrode the flesh of any soul caught within its realm, dissolving them into the same blood mist that fills the air. It is akin to being surrounded by poison that attacks the victim from without and within until they are completely destroyed. As the same time, the damage inflicted upon the victim(s) is used to empower the castleÆs effect further, using the blood mist they produce to make the atmosphere even denser and more corrosive.
Kisuke is able to use this same energy directly, gripping it as if it were solid material and shaping it into different forms to both attack his opponents and defend himself. Whilst there is a certain unpredictability to this type of manoeuvre, he will primarily replicate the same techniques that his shikai is able to produce though the scale of effect is greater and more dangerous.
The nature of this bankai makes it impossible to use when his allies are in the same vicinity and is only suitable for when facing an enemy Kisuke has to kill. For this purpose, he created a specialised kido to protect one or more allies from the effects of his bankai to allow them to fight by his side. As the bankai is KisukeÆs ability, only when he is the one performing the kido will it have any effect, making it useless should someone else try to defend against his power with it. Even then the kido doesnÆt grant total immunity and relies on KisukeÆs ability to maintain, making it an extremely dangerous prospect.
Name: Resurreccion: Murcielago, Bat
User: Ulquiorra Cifer
Ability: This is UlquiorraÆs released state that transforms him into a bat-like creature, vaguely reminiscent of certain myths regarding vampires. However the abilities he possesses in this form are ones which best reflect his nihilist nature. In this state, the nature of UlquiorraÆs reiatsu can be considered the incarnation of the concept of ænothingnessÆ; he is able to shape his spiritual energy into weapons that are made to do nothing more than eradicate anything they touch. Both matter and energy are destroyed when coming into contact with this power, being erased from existence as his reiatsu completely deconstructs them. Primarily, Ulquiorra shapes this energy in the form of javelins which he uses either in close combat or to throw as ranged weapon.
This power is also what gave birth to the Cero Oscuras, Dark Zero, which takes on a different appearance and power from other Cero types. This is due to it combing the usual destructive power of an EspadaÆs Cero with the matter-destroying nature of UlquirraÆs reiatsu, making what is arguably the stronger type of Cero in existence and one that only the former king Hueco Mundo can replicate.
Despite how powerful this resurreccÝon sounds (and is), it is still subject to the rules of reiatsu meaning its effectiveness is lessened to some degree against other spiritually powerful beings. At which it æmerelyÆ becomes incredibly lethal rather than completely unstoppable.
Ulquiorra is also the only known arrancar to possess a form known as Segunda Etapa, Second Stage. Despite the change of appearance, this form does not increase the volume of his reiatsu or improve his physical abilities. Instead the only other thing that changes is the nature of reiatsu which reflects the core of UlquiorraÆs identity even further before. The reason he refers to this form as ôTrue Despairö is because his reiatsu becomes able to affect the mentality of all who feel it by inflicting his own nihilism upon them.
His complete disregard for the meaning of life is able to attack the psyche of his opponent, draining away their positive emotions and everything that driving them to fight which results in them giving into despair. The longer they remain in his presence then the more mental trauma is inflicted until they are crushed under the weight of hopeless.
Name: Resurreccion: Ira, Wrath
User: Yammy
Ability: As a being that revelled in war and rage whilst living and devoured souls of the same temperament in death, YammyÆs released state truly reflects his wrathful nature. His body shrinks down until he matches the size of a tall, incredibly muscular man, in contrast to his reiatsu to swells immensely. His masks curves from his mouth to the back of his head, he sprouts two extra pairs of arm from each shoulder, his legs become shaped like a goatÆs and a hammer-ended tail extends from his lower back.
Unlike like other arrancar, when Yammy releases his personality changes along with his physical form; his tone of voice, facial expression and general demeanour all express an extreme sense of calm on the surface. However this is only on the surface as in reality, his anger grows to such a degree that itÆs beyond the comprehension of others whilst becoming extremely focused. Whereas YammyÆs immature attitude would usually be his main weakness regardless of how much power he possess, in this state he becomes truly deserving of the title Cero Espada.
The main ability he possesses in this form is that his reiatsu grows in proportion to how angry he is, resulting in his strength and endurance gaining a continuous boost though his appearance remains the same. Due to his personality, this means that the longer a fight lasts then the more powerful he becomes. The only time this wouldnÆt be the case is if Yammy suffers damage during combat at the rate that surpasses the speed of his anger-induced growth.
Another unusual aspect of YammyÆs resurreccÝon is that it doesnÆt only affect himself but also his hollow dog, Kukkapuuro. The creature had been in his presence ever since he was an adjuchas, feeding off of his reiatsu the entire time which created a unique bond between them. When Yammy releases, Kukkapuuro undergoes his own transformation which significantly increases his size and power whilst his personality becomes like that of a berserker. He will attack everyone in sight bar Yammy and his power increase puts him on par with an Espada.
Name: Chimera Parca: Ayon
User: Sun-Sun, Apache and Mila-Rose
Ability: Ayon is a monstrous creature that HalibelÆs fraccion are able to create by sacrificing their left arms and fusing them together. The three of them arenÆt entirely sure whether their æpetÆ is actually something they create or if he is summoned from someplace deep within Hueco Mundo. Nevertheless, he possesses power on par with an Espada and is willing to fight for their cause.
As a chimera-like being, Ayon is able to shape shift parts of his body into entirely new forms. The simplest use of this ability is when he increases his muscle mass within a certain limb to increase his physical strength, usually to crush a target with as much force as possible. But more than this, he can shape his arms and legs into natural forms of weaponry such as hammers, blades and maces. Grows new limbs and appendages is possible for him so that he can generate wings, tendrils, extra eyes and arm to name a few examples.
He is similar to hollows more than arrancar in the sense that he has no internal organs and appears to be a sentient mass of muscle, blood and flesh. This allows him to continue fighting and pulling himself back together even when he suffers huge amounts of damage. The most idea way to kill him is to completely eradicate his body.
