Devil fruit weapon Heyato the boomerang (revision number three)

Name: Devil fruit weapon Heyato the boomerang

Physical Description:
-Dormant form-
Heyato appears as an elegantly crafted, skillfully made and very light weight darker bluish steel boomerang with rounded edges over most of it but a defined sharpened edge along the outside and pointed corners, making him seem rather unorthodox and dangerous to throw as a returning weapon. The boomerang is just over a foot long and bends at the proper forty-five degree angle with a slightly brighter metal tone on the edge and a slightly darker metal tone on the blunt side. The right wing of the boomerang is engraved with the name “Luna” and in smaller; finer print in cursive the words “devil weapon, vampire bat” can be seen.
-Bat form-
Heyato appears as a larger than normal vampire bat with dark brown fur black eyes, a wrinkled snout and large ears, a fanged mouth and a squat furry body with larger hairless wings and large complex ears. Heyato rarely assumes this form as it is a liability as he is made entirely of flesh in it and because peoples opinions on weather he is frightening, ugly, majestic, adorable or strange looking depend widely on the person and reactions very just as widely.
-Hybrid form (base)-
The hybrid form is larger still than both forms, about twenty inches long and has bladed wings, sharp claws and fangs and is made entirely of living metal with metallic fur, in this state he carries the engravings on his back. This is the form Heyato normally remains in.
-Screeching form-
A form unlocked with Heyato’s I.Q. evolution, this is similar to the hybrid form but with decidedly larger ears and slightly smaller in size with a darker tone to his body. This form both enhances and provides protection against Heyato’s vocal screeches and enhances hearing ability and tolerance. This form enables the use of the earsplitting screech and the hell screech while enhancing the effects of the distortion sonata and the crimson aria’s sound based applications.
-Blade form-
A form unlocked with Heyato’s I.Q. evolution, this is larger still than the hybrid form but is almost entirely in the wings, which are now much larger and comparable to ace or sword edges. Though still fully mobile this enhances his melee combat abilities and his control over air currents though its enhanced oversized wings. The body double slashing, piercing dive and crest shield skills can be used in this form and it enhances the effectiveness of the flash flicker, and wing cleaver skills while enhancing the air blade aspects of the crimson aria.
-Night flyer form-
Heyato’s final form created by life return and his previous two forms Heyato doubles in size to less than four feet across, large enough for Sano and one other to stand on and fly, able to harness the advantages of the blade and screeching form temporarily (lasts for 6 posts) before losing consciousness after expending so much energy (also for 5 posts, 5 post cooldown after that, limit twice per thread, usuable only with S.I.Q.)

Special abilities:
-Enhanced alloy-
Being the invention of a family of weapons dealers Heyato’s body is composed of a family recipe blend of tempered steels and coatings, which render him rust-proof, sturdy enough to shrug off bullets and fly though flames un-phased, in hybrid form his conductive prosperities have similarly been greatly reduced, more so by his status as a semi-organic being
-Devil fruit-
Heyato is a edged metallic boomerang that has been “fed” the Kori Kori no mi model Kyuketsuki (Bat bat fruit, model vampire bat); as such he has a living consciousness, fully lucid and animate despite being once lifeless. This also affords Heyato with the ability learn, train himself, grow and obviously to control his devil fruits powers which include the ability to shift his form between that of the weapon he was created to be, a vampire bat and a hybrd between the two, though through use of the I.Q. plants and S.I.Q. he’s eaten, more forms have been unlocked.
-Inorganic-organic body (passive)-
Though he is a thinking living being Heyato was ordinal a body of inanimate steel enhanced with a devil fruit, because of this he does not necessarily fall victim to the follies of being an organic being. Because he can make himself “selectively organic” by shifting between vampire bat form and boomerang form the effects of disease, poison, drugs and even that of hypnotism do nothing to effect him. Though he is a devil fruit based being submerging Heyato in sea water will merely cause him to revert to his in-animate object form, rather than die (seastone also just reverts him as long as its touched him). Heyato also does not age, being not principally a living being to begin with. As he blurs the lines between object and animal scratches along his boomerang surface heal over time and blacksmith work can heal the animals grievous injuries. In his hybrid forms his entire body is fundamentally made of living steel, flexible as flash but solid as metal.
-Super-animal sensory ability (Echolocation)-
As a bat Heyato’s sensory abilities were already quite different than that of a human, though possessing poor eyesight, especially in bright areas Heyato has always been able to use echolocation to more than compensate for his visual shortcomings. Since then Heyato has honed his echolocation to a level unknown to even other bats to the point where it seems like an extra-sensory ability in and of itself, the bat being able to alert others to potential danger that is totally invisible, simply by hearing the sound waves bouncing off of individuals and objects, or sounds as faint as heartbeats. Though this does cause him to have a high sensitivity to loud noises the fact that his eardrums are often living metal prevents him from being deafened by them, this makes him an excellent tool for locating hazards and ambushes. As a vampire bat Heyato’s sense of smell is on par with his hearing, going beyond the level of most tracking dogs and on par with vultures and sharks, able to discern a desired scent from miles away, this makes him ideal for tracking individuals.
-Vampire bat’s feeding (passive)-
Though Heyato does not require sustenance to live due to his non-organic true form his vampire bat status shows itself in his ability to absorb blood by breaking down the iron in his saliva for use in his metallic body and use its proteins as fuel in his various hybrid forms, this causes an increase in Heyato’s physical capabilities proportionate to the blood consumed, more blood will increase his speed strength endurance agility and reflexes more greatly over a longer period and less over a shorter period with less blood. Even in his inanimate state Heyato can absorb the iron in blood to repair injuries in his metal body, enabling a regenerative effect.
-Anti-coagulant production-
As a vampire bat Heyato possesses the power to produce a chemical native to real bats of his kind, an anti-coagulant that stops blood from clotting. This naturally occurring substance has since been “weaponized” to prevent the effects from life return based healing factors or blood control to stop bleeding caused by injures from anti-coagulant covered edges fangs and claws, though the agent comes from his mouth Heyato can easily coat any body part in this substance. If left unchecked in the bloodstream the agent will cause the blood of the victim to thin out similarly to the effect alcohol has on the circulatory system but is useful in the preventing of strokes.
-Numbing agent production-
As a vampire bat Heyato possesses the power to produce a natural numbing agent, when introduced to the blood stream this agent numbs all pain in the localized area for duration of time, this can be used as a painkiller in small doses or a useful tranquilizer in excessively high doses as overdose of the numbing agent can cause light headedness, weakness of limbs, and potential loss of consciousness. The numbing agent is however not at all dangerous to humans on its own but does allow for Heyato to feed on targets with out their noticing.
-I.Q. Enhancement (passive)-
By consuming the I.Q. plant Heyato has undergone rapid hyper-evolution, which has caused the “wavelengths” of his devil fruit to alter, giving him new forms to take with his body and simultaneously better adapting his existing body to its environment by enhancing his sensory and physical attributes to the bat’s equivalent of super human.
-Physical prowess-
Heyato is at home in the open air, able to fly with far greater speed and skill than even most birds can Heyato possesses a physique capable of using rokushiki like skills and exceptional ability in his small yet powerful body having trained for decades.
-Life return-
Heyato has learned some degree of life return to be able to produce his numbing agent and anti-coagulant at will even though the edges of his bladed wings. He also uses life return to repair himself with absorbed blood’s iron and use his final night flier form
-Unique Navigation (sonar)-
Heyato is a rather unorthodox but talented navigator, able to survey an area and memorize a “sound map” of the location and refer to those maps later on, in the process of navigating an area by comparing it to his sound maps Heyato also employs a passive form of sonar that aids the ship he is navigating for exponentially in spotting hazards and other ships before they would come in to visual contact. Heyato can also direct his sound waves to the water to scout for submarines, sea-kings or fishmen allowing the ship ample time to escape.
-Atypical flight-
As a boomerang Heyato is not limited to only bat like flight, if necessary for maneuvers and attacks in the air he can easily begin to fly like a boomerang with stationary curved wings, even rotating at high speeds with out getting dizzy, thanks to his echolocation, this is especially useful in avoiding attacks or turning on a dime.
-Animal empathy with Sano-
Heyato was created expressly for Sano Luna at birth, and spent his entire lifetime with the later, as Sano has with him. This connection combined with the fact that Sano alone was the one to train and instruct Heyato gives the two of them an unparalleled teamwork and communication unseen by most beast-masters. Just as Sano can interpret Heyato’s every gesture and squeak Heyato can interpret Sano’s intentions even with out words. Highly intelligent for a bat the two of them have a teamwork born from this empathy that is so strong some believe it to be a telepathic connection, when in reality it is just the result of over two decades of spending every waking moment together.

Learned techniques:
-Flash flicker-
A unique skill developed by Heyato, with his super-animal powered wings he beats against the air at a staggering speed with more than ten full beats in a single second to cause a Soru like movement, with Geppo’s maneuverability in the air, comparable to the “Razor” rokushiki technique which combines the two previously mentioned skills. Flash flicker enables soru speed movement in air but does not run the risk of having to stop movement as Heyato can glide even with out beating his wings. This is often used in Heyato’s basic attack in which he flash flickers past a target slicing it as he flies by with a sharpened wing. Flash flicker will leave an after image of Heyato just after its use, which flickers away just as Heyato flashes in to the other end of his dash hence its name. The after image is a trick left by the reflective light of Heyato’s metal body moving at such high speeds but serves well to distract opponents to his actual location.
-Wing cleaver-
Though many solders of the world government can sling air currents in to blades with their legs, and pirate warriors often use the edges of blades to accomplish the same no tool is best for manipulating wind currents than that designed by nature, the wing itself. With that in mind Heyato eventually developed this skill based off the humans rankyaku and air slashing techniques, mid flight or glide, but especially during a turn or pivot Heyato extends his wing and using the air current already flowing over his wing mid flight directs the air in to a bladed compressed current with a simple forward turn, though the arked blade isn’t as large as a blade produced by a sword or human leg simply because of the wings size difference it makes up for this disadvantage both in speed, maneuverability and pure utility, as Heyato doesn’t even need to stop flying to perform this technique it can easily be done simply when passing a target, allowing him to slice them with out having to get close enough to risk direct counter attack. (blade form increases wing cleaver to the effectiveness of ryanku with out sacrificing any advantages)
-Spinning wing cleaver-
A typical wing cleaver attack made continues by Hayato's atypical flying ability, rather than one slash the wings become a variable buz-saw of air cutting power as a cutting around the body is maintained by the new type of movement, this current also serves to divert materials to either side of Heyato making it effective for both offense and defense as well, used to fire off wing cleavers in situations where normal flight cannot be maintained.
-Piercing dive-
Heyato performs an extended barrel roll maneuver mid flight directing air currents around his body to become a flying drill like tornado’s center and flies toward an opponent, this is a devastatingly powerful but simplistic attack used to outright drill though things or at the very least strike with considerable force and sharp damage. As he does not use his eyes to navigate, and retains echolocational function while spinning he does not lose ‘sight’ of his targets, though turning in this state is difficult but shifting in and out of the spin is quite elementary. This is equally effective to lose a pursuer (as the blade like currents of air trail behind) or knock away something flying directly to the left or right such as a projectile with the side of the wing. This can also be used to rebound Sano’s missed shots by ricocheting them off his wing and back on target. (the effects of the numbing agent and anti-coagulant retain their use in this technique as it makes direct contact)
-Crest shield-
Heyato performs a rather complex movement which takes advantage of his boomerang status, his wings outstretched he spins vertically clockwise like a rotating disk in front of Sano or ally, deflecting them from oncoming projectiles which are fed in to wind currents directed by the rotation’s force and channeled away in other directions, leaving Heyato’s iron body still untouched.
-Air countering wave-
Heyato flaps his wings backward rapidly creating a high pressure body of air in his wingspan and a low pressure body outside then flings the unstable bodies of air forward with his wings, creating a compressed air wave that exists to disrupt existing air currents, effectively used to parry air based attacks and dismantle the currents at the base of whirlwinds and tornado shaped attacks.
-Body double slashing technique-
Heyato flies forward toward a target then executes a wing cleaver with both wings while simultaneously flash flickering backwards, the result is that Heyato appear to fly forward and actualy dive in to the opponent becoming the center of a full body arched slash attack, when in reality this is simply an afterimage and a compressed wave of air, used both to get out of situations and surprise attack. (the full body air slash is also available with out the flash flickering)
-Deception screech-
A simple enough skill in which Heyato uses his understanding of sound waves and their ability to bounce off surfaces to employ a simple ventriloquism, throwing his voice to make it come from different directions unknown to others. This can be used to fool individuals but can also be used to bounce sound based attacks (like the distortion sonata skill) off of surfaces and change their direction; ventriloquism also increases his echolocation abilities range and focus.
-Distortion sonata-
A technique in which after being thrown by Hayato rapidity flash flickers all around a target darting in different directions using the boomerang like wind force to pivot on air rapidly between each dash, passing them from all sides at multiple angles while making a series of shrill screeches, thanks to his high speeds and the Doppler effect this creates a situation where the targets inner ear is struck with many varying frequencies at high decibels very quickly, resulting in a loss of balance, disorientation, vertigo and dizziness. The victim experiences a very sharp instantaneous decline in motor skills to the point where standing becomes extremely difficult, their vision begins to spin and the area around them appears to warp and distort itself, making navigating the area much less focusing on one individual target or opponent among the flash flickers many afterimages is next to impossible. As the sonic assault moves at the speed of sound the target will not realize the effects of the attack until they hear the screeches, making it devastatingly effective against hapless targets. This is commonly used to non-violently subdue targets, the noise making it exceptionally difficult to locate Hayato at his enhanced speeds. This technique is equally effective against large numbers of opponents as the area around which he flies can easily increase. This can be combined with the deception screech skill for added effectiveness, range and even further difficulty in locating him if the location has enough surfaces to bounce sound off.
-Earsplitting screech-
Most unlike normal sonic attacks that cause hearing to damage, in this technique Heyato throws a cry at such a frequency as to cause a state of severe hyperacusis in the victim, causing an over-sensitivity to certain frequency ranges of sound (put another way, a collapsed tolerance to usual environmental sound) which causes the effected individual to become excessively more susceptible to Heyato’s other sound based attacks (see distortion sonata), more than doubling their effectives and outright preventing the effectiveness of covering ones ears with mere hands or use of plugging with fingers, this also disables the victims acoustic reflex (which normally serves to reduce the shock of intense vibrations in the inner ear when exposed to loud noises). This effect lasts for three hours (the duration of most fights). As the screech is “thrown” using ventriloquism (see deception screech skill) this technique does not run the risk of effecting nearby allies and targets single individuals, while retaining its speed of sound effectiveness meaning that the victim does not hear the screech until it has already affected them. Victims of the temporary hyperacusis suffer from such high sensitivity to sound that every day sounds that would not bother anyone are suddenly intolerable, sonic based attacks also carry the ability to shatter concentration, and cause actual shock and pain due to the acoustic reflex being disabled, adding a minor stunning effect to such attacks. Damage to the inner ear that reduces motor skill and balance is also made more effective and inflected with greater ease. Earsplitting screech does not stack with multiple uses under the same duration on the same target.
(Earspliting screech can be used to stun the victim long enough to move in for a distortion sonata, the two techniques are very often used in tandem to increase effectiveness)
-Hell screech-
Hell screech employs the brains natural responses to sound with the victims base instincts to create a sound wave that causes intense misophonia to the sound of bat screeches for a short time (three posts) This will cause the victim to feel intense hatred and annoyance at the sounds of the screeches to the point where they lose all focus, unable to think of anything accept for how annoyed with the sound they are and how desperately they want it to stop, when combined with a hidden vantage point and the ability to bounce the screeches off walls (see deception screech) this can prove a very effective means of psychological warfare, the torturous sound echoes from all sides coming from seemingly nothing filling their ears and mind with its shrill, annoying, terrible, nightmarish noise, rattling the head and causing great stress and discomfort. It is similar to nails on a chalkboard with the worst possible migraine and hang over, when combined with the effects of the Earsplitting screech this is actually very physically painful and inarguably cruel. Though the methods are quite unkind it is a solid way to defeat someone with out having to fight them or injure them, as the victim will likely simply give up or run away if the sound continues to torment them. Hell screech’s effects stack and can be used once a post, even when flying and moving. Like the other sonic attacks it is “thrown” with ventriloquism to avoid damaging the user’s master or allies.
-Crimson aria-
A variation and improvement on the distortion sonata coupled with wing cleaver attacks aimed at the target as Hayato flies past them, resulting in a barrage of air slashes from all sides and every conceivable angle in addition to the normal effects of the distortion sonata on the victim sensory balance and motor skill abilities. The result is a powerful attack from all sides coupled with the inner ear disruption, making the attack extremely difficult to counter or block effectively, further this technique can continue for longer periods of time as Hayato catches blood from opponent’s and increases his speed, this technique does require Sano to throw him first but is used to utterly subdue targets by slashing at them till they are utterly defeated, this technique can continue to wear away defenses and the inner ear disruption makes the concentration required to maintain a guard such as tekkai moot. As the inner ear disruption distorts both vision and hand eye co-ordination a block or counter attack is also highly unlikely, as the attacks are made of air and coming from all sides and angles its equally unlikely that the user will block the blades themselves or be able to escape easily. This technique is especially vicious because the blood from the victim accelerates the speed of the flying assailant and his attacks. (just like the distortion sonata it can be combined with other sound based techniques and just like other blade based attacks it can be combined with blade form to add to the lethality but one use cannot have both unless in night flyer form)

History:
-Background-
Edmond Luna, a self-made shipyard worker turned trade company tycoon who bought his way to nobility on his own efforts had recently established a home in the distant island of Saint Reia in the south blue. From his mansion there he kept an eye on the affairs of his company and expanded to arms dealing, selling and manufacturing quality goods for sale to anyone, marines and pirates alike, even revolutionaries, this made him fabulously wealthy and successful but earned him many enemies, thinking ahead Edmond wisely cornered a number of devil fruits for use in creating a dependable, betrayal-proof force to guard his family and fortune. This came to be known as the vanguard project.
-Origin-
Edmond Luna and his wife Mercedes Luna had four children, in order they were Yoru, Clairese, Sano and Valentine Luna. Edmond had procured six devils fruits, all zoans and decided that it was best for each family member to be given a zoan enhanced living weapon to protect them against thieves and wealthy rivals. During the vanguard project as it was later known the zoan of a smaller animal, a vampire bat was imbued in to a weapon he felt fit the animal well, a flying boomerang. This he entrusted to his youngest son, Sano to be his companion and protector for the rest of his life.
-Childhood-
Sano and Heyato grew up in social isolation, not being aloud outside the mansion by their paranoid parents who were often absent most of the time Sano and Heyato were born in to a life of ease but seclusion. They were however content to live a luxurious life for the time being despite having no one but their brother, sisters and servants around. This did give Sano plenty of time to teach and train Heyato and bond closely with the animal which fast become less of a pet and more of a best friend. It was only natural that Heyato would follow Sano when he eventually broke free and disowned his family to join the navy.
-Navy training-
Heyato, much like Sano had a harsh awakening in their naval training, Heyato was trained to be a war and reconnaissance animal for ships and to deliver messages while Sano was trained as a sniper, both gravitating from their easy life as heirs to hardened solders driven by the suffering and corruption Sano had bore witness to. Eventually Heyato regularly delivered messages between ships and assisted in the location of targets for the navy as a marine’s pet.
-Aboard the naval ships and depature-
When Sano was finally taken to a crew of marines for field duty Heyato accompanied him on his voyages, serving as more than just a scout and saving Sano’s life on more than one occasion. He became a welcome addition to the crew for many reasons, and almost the crew’s sort of mascot for a time. Eventually Sano found himself the first mate of his crew and he was never seen with out Heyato on his shoulder something that would grow to be his trademark. When a chain of unfortunate events caused Sano to break from the marines service Heyato assisted in ferrying him from place to place, Sanos only companion in the world as a wanted fugitive. Eventually Sano would come to become captain of his own crew of outcasts and visionaries inforcing their own law on their own terms in a world full of crime and corruption, finnaly getting revenge on the corrupt marine who wrongly framed him.
-Adventures in the matchlocks-
During the many escapades of Sano’s vigilante crew, fleeing from marines yet leaving a trail of captured criminals, escaping from prisons, going up against crews of pirates and even saving one another from execution Heyato was always instrumental in Sano’s plans and stringy, this continued for a year, as Sano’s philosophy and vision began to grow, so to did Heyato’s faith in him.
-New world-
Finally the crew resolved to leave the world behind and start anew in the new world, tired of the meaningless, endless, pointless fighting between factions that never gained any ground, revolutions that never came, governments that protected the interests of all the wrong factions and pirates who preyed on the innocent they set out in search of foolish dreamers and utopias with hopes in their eyes. It was on this expedition that tragedy struck the crew and Sano and Heyato were the only ones to survive unscathed, tragically.
-Founding of the new nation-
After the horror of losing their crew Sano had allot of time to think marooned on an island in the new world, he spent this time deep in contemplation and the task fell to Heyato to provide food and water for the distraught, shell of his former master. Over time however Sano came to understand a new vision, and the two set out to accomplish a greater dream, understanding then more than ever what was most important.
