Fan Made Zanpakuto

Sabi

Name: Sabi.

Translation: Rust.

Weapon Classification: Katana.

Type: Elemental.

Subtype: Earth.

Base Appearance: The Katana is rather unique as the hilt is an oval shape and the grip is a basic brown but it's the sword that's unique as it takes the form of an advanced rusted sword that looks like it's going to crumble if one were to look at it funny but despite its appearances, it's structurally sound.

Shikai Command: Crumble

Shikai Activation Design: When the activation command is given, the rusty blade crumbles into a cloud of dangerous rust metal, only leaving behind the pristine and clean hilt and grip behind.

Shikai Appearance: The Form of Sabi is actually a cloud of rust metal that is in the air, it may seem like a feint red cloud but it's actually dangerous rust particles, the hilt and grip remains as it did in the sealed form.

Spirit Appearance: Sabi takes the form of a man who lived in a post apocalyptic wasteland from a mad max movie, he wears tattered military desert camo uniform with a tattered and dirty brown cloak over the shoulders, he wears a lower face mask with a skull jaw pattern and has highway patrolman sunglasses that reflects everything in the mirror shades.

Spirit Personality: Sabi is an incredibly gruff and angry individual as one would expect of a road warrior of a rusted society, he is often distrustful and even at some point refused the user the chance to learn Bankai from it as if the user would betray it but deep down, hes incredibly soft and by learning and easing into Sabi's heart then he will protect him as a member of his pack.

Shikai Abilities: The base ability of Sabi is that the user can mentally control the effect of the rust particles as effectively as one would for their body, almost operating in a similar manner as Senbonzakura but unlike visible cherry blossoms, the user controls very hard to see grains of metallic rust.

The user can mold this metallic cloud of rust into anything the user needs such as weapons, armor to simply using it by itself as a weapon but the effect that it grants the user that it can corrode essentially most materials into dust, turning metal into more rust particles to take control and reduce other earthly materials into grains of sand that can't hold its shape, this is also similar to the effect when fighting against swords, however Zanpakuto's being made from spiritual energy takes a lot longer to rust the metal enough to break it though with exceptions is that those with strong spiritual energies are immune to Sabis rust effect of their weapon, there body is a hell of a different story.

When the rust particles enter into an organic targets blood stream, the start inducing a string neurotoxin that causes extremely painful muscle spasms that would be extremely difficult to do anything else however if struck on a place where major nerve activity takes place like the heart or the head then the whole body shuts down and entering a form of rigor, luckily the rust induce toxin isn't lethal as it will pass after an hour.

The user can also expand the rust cloud to its maximum length of 150ft around the user while remaining connected molecularly which by doing so allowing it to distribute its Passive neurotoxin into an airborne toxin, anyone besides the user attempts to breath in the air that the rust particles causes the neurotoxin to enter their lungs causing them to have complications to breath while within the air and lasts for an hour when they exist the rust cloud.

Bankai Name: Shūmatsu sekai no sabi

Bankai Translation: Rust of the Apocalyptic World.

Bankai Release Command:(Optional) None.

Bankai Activation Design: Once Bankai is activated the rust will stop as if its frozen in mid air before quickly surrounding the user in a solid ball of rust metal particles before entering the users body fully, the user is now inhabited by the rust particles, the arms is now changed to a full brownish red metal which is made entirely of rust particles while rust is pumped throughout the user without causing any metal poisoning.

Bankai Design: The Rust changed from a cloud of metal particles and it enters into the users body which covers and changes the users arms to be two arms made from pure brownish red rust, while trace remnants of rust particles are pumped throughout the entirety of the blood system of the user even if no one but the user knows this aspect of the weapon.

Bankai Spirit Appearance: No Change.

Bankai Spirit Personality: No Change.

Bankai Abilities: The base aspect of the rust now occupying a physical aspect of the users body grants the user an incredibly strong metallic armor that can withstand strikes from even Kenpachi Zeraki without withstand much of a scratch.

While the armor is indeed an incredible boon, it's true physical connection is the trace particles of rust throughout the users bloodstream which allows the user to have 100% control over their bodies physical movement meaning no matter what type of injury that they sustain, so long as the user is awaken then they can potentially remain fighting for eternity regardless of the amount of injuries that aren't grievous or deathly to even ignoring outright exhaustion until the body collapses.

Now with the physical aspect outside of the armor and benefit from rust in the bloodstream, the users effect of the rust as a weapon has also increased in power which the lethality of the poison induced by the rust particles has also become extremely deadly, even single strikes to targets without strong spiritual energy can wither and break, striking objects that don't have strong spiritual energy will crumble into dust or rust near instantly while organic objects not protected by strong spiritual energy will wither and turn into dust.

The rust also feeds off of spiritual energy as such when gets struck to a target with high spiritual energy, the effects of the weapon itself as well as its neurotoxin is slowed until the infection eats more and more spiritual energy for it to have enough exposer to induce its effect, those with weak spiritual energy will be near incapable of fending off the infection and wither and crumble into sand and rust.

The user can also morph and mold there rust metal limbs into any weapon that they so desire or even shoot a range of rust based weapons out of their palm in rapid succession or in a burst like a shotgun blast.

The user is capable of compressing a powerful ball of air within the palms containing strong levels of rust and oxidation which the user can unleash a massive blast of air strong enough to wipe away a battlefield of weak soldiers, turning them all into dust and rust.

And lastly the user can conjure form a clone made from pure rust in the complete likeness of the user, it will have everything the user has, from their abilities, straight down to their memories and mannerisms making them an extremely difficult opponent to fight against as the Rust Clone can fight to a 90% Effectiveness as the original.
