Wyrm Soul: Culebre

Wyrm Soul: Culebre (, Uirumu Sōru: Kurebure lit. Phantasmal Dragon: Venomous Brutal Dragon) is a Take Over spell, specifically that of Take Over: Wyrm Soul, that enables the user to transform into a Dragon (, Doragon lit. Cryptid of a Wingedkind); which are extremely powerful and flight-capable legendary creatures that are a strange mixture between serpentine, reptilian and avian traits that live in – in this case, when harnessing Wyrm Soul: Culebre, the user transforms into the Absolute Toxicity Dragon, Culebre (然毒竜・, Zendokuryū Kurebure lit. Venomous Brutal Dragon), an exceptionally powerful dragon of ages past with dominance over the element of poison; his  was capable of producing all sorts of poisons, which are substances that cause disturbances in organisms, usually by chemical reaction or other activity on the molecular scale, when an organism absorbs a sufficient quantity that could kill anyone and anything that he deemed fit, punishing those who double-crossed him or happened to get in his way with all sorts of cruel, unusual deaths. The "wielder" of Wyrm Soul: Culebre is Mytyl Sejren, a member of the Sejren Family whom was kidnapped at an early age by Mosag Tenjouin, the previous head of the Magic Council during the interim between Daybreak and Fairy Tail: Dawn as part of an experiment by the Research and Development Department in order to create new s after the Manmade Dragon Project was a failure – not only that, this experiment involved the of dragonkind through  as to bond the souls of the dragon and the host by way of confiscation induced by the implantation of experimental synthetic dragon's blood, transforming the host into an empty shell – indeed, Culebre seems to have destroyed Mytyl's soul, taking over her form and rewriting her personality to suit Culebre's own. Soft-spoken, Culebre's speech betrays his immense sadism and love of bringing people down. Acting as one of Alexis Tenjouin's main enforcers, Culebre is one of the few whom knows of the real reason why the leader of the Magic Council has become a despotic tyrant.

Culebre's "real" identity is that of the previous Ouroboros Hellion (ウロボロス・ヘリオン, Uroborosu Herion) before Sion Kenzaki, and one of the first Hellions to come into existence, being corrupted with the Amadam Virus in the Old World by Devius back when the two and Dzerve Sejren were co-workers – Culebre, in his human form known as Joachim Edelweiss (ヨアヒム・エーデルワイス, Yoahimu Ēderuwaisu), was Devius' first victim, having his inner darkness corrode his heart as he was transformed into the Ouroboros Hellion. A genius even after his corruption into an inhuman abomination, Joachim assisted Devius in reverse-engineering the Black Soul Armours from Dzerve's Soul Armours and helped create the armour used to enslave Signa before he was seemingly slain by Dzerve as Soul Armour Knight Tachys by using the Victorize Kick Limit Break. However, Devius' Universal Reboot reset the Old World and thus Joachim, like all remaining beings in the Old World with the exception of Devius reincarnated on ; befitting his lowly nature, Joachim was reincarnated as a snake; however, when Magic arrived upon Earth Land soon after due to the incomprehensible amounts of despair and hope in said dimension surging throughout the multiverse and affecting as well as the other two dimensions; causing the animal kingdom to undergo a rapid evolution, blending their Deoxyribonucleic acids with that of the despair energy created by the Hellions to mutate their existences into that of dragonkind, his previous memories were awakened, and recalling that Devius had given him a specific set of instructions, Joachim, becoming a Dark Dragon, followed through with his master's plans, inciting countless conflicts as to gather the despair needed to open a Dimensional Gate to the remains of the Old World where Devius and Signa were stranded, serving as the agent of his master's revival.

Appearance
Culebre is an enormous Western Dragon (洋龍, Yōryū), which are the most common type of dragon, from eastern part of Earth Land that's occupied by a very large peninsula called  (, Ishugaru lit. Continent) which is surrounded by scattered isles of differing sizes; indeed, the Absolute Toxicity Dragon is a large, fire-breathing, scaly, horned, lizard-like creature as stereotyped in all sorts of myths; the creature also has leathery, bat-like wings, four legs, and a long, muscular prehensile tail that can be utilized as a fifth limb for all sorts of purposes. Culebre himself, as a member of the Dark Dragon Clan, whom are the most brutal and violent of dragonkind, is known to possess a certain look about him that makes him stand out from the rest of his kin and other types of dragons – Culebre is known to be textured in dark purples that are juxtaposed by light peachy colours - the darker colour of deep purple is focused mainly around his fleshy underbelly and upon his lower arms- there are also some dark purple parts at the bottom of the head-scales. Culebre possesses a chest attachment that is shaped in a similar manner to the underbelly of a snake, completely vaguely dark-green in texture with a myriad of red markings arranged at the sides – Culebre's main body portion incidentally resembles that of Eastern Dragons, being anorexically thin to the point that people would probably go force him to eat something if he were human (or remotely likeable). The peachy-textured portions of Culebre's body appear as if they were composed of a variety of plants, with vaguely organic features, with cracks and all sorts of unique patterns embedded within them- these are often accented by dark red markings similar to runes. Culebre himself, unlike most Western Dragons, has no wings, instead possessing two purple protrusions from his back that resemble the engines of a jet – indeed, he runs instead of flying.

Culebre's claws are larger than the rest of his arms, giving off the visage of them being gauntlets; the deep red has the crystal-esque peachy parts as a lining, with vein-like patterns superimposed over the purple majority; the dragon's talons look like flexible pillars of crystallized poison that have been simply attached to these gauntlets. The dragon's legs are quite similar, though the peachy and purple parts have been reversed in terms of prominence; five baubles of sorts are attached to Culebre's feet, from which thin claws extend- this counts for both legs. The dragon's tail has no real features aside from the red orb at the top- it is rather powerful, capable of knocking down a skyscraper just by collision damage. Finally, the head of the Absolute Toxicity Dragon is accented by the dark red 'V' patterns on his neck; he has a fearsome, threatening glare no matter what he's doing. There is a pair of gigantic, pointed scales extending backwards from behind his head, serving as 'vents' of sorts- with a ruby embedded within his forehead and dull, green eyes, Culebre's horns, attached to both sides of his head, are notably large and curl around rather extensively, giving off the visage of the horns of the devil as depicted in Christianity. Culebre's chin has a prominent spike extending forwards. Overall, Culebre incorporates several features of deadly plants into his body in regards to design, including several Venus Flytrap maws, thorns, and petals- his tail also resembles a vine, causing him to resemble a horrifying monstrosity with eyes and mouths everywhere instead of anything that could be properly categorized as a "dragon", being a heavily distorted and corrupted version of those winged cryptids whom embody absolute power; it's said that this owes to the origins of dragonkind in the Sun Trilogy.

Personality and Traits
As a member of the "Dark Dragon Clan", it should come as no surprise that Culebre no matter the era he's in is a rather unpleasant fellow. One of the first dragons to come into existence alongside Ashur, Níðhöggr, the Five Elemental Dragons, and Ambrosius, Culebre, like all dragons, mutated from his previous animal form – in this case, in his previous "life", so to speak, Culebre was a snake; and indeed, the Absolute Toxicity Dragon fits the stereotypes associated with these elongated, legless, carnivorous reptiles all-too-well. Cunning and sly, Culebre is an expert planner despite the fact that dragons are more well-known for their truly immense power more than anything else; as such, he prefers to remain hidden in the shadows yet in plain sight, deflecting any suspicions due to his inconspicuous nature. During his time as Joachim Edelweiss, the A.I of Dzerve within the Phoenix Driver told Tsuruko Sejren that Culebre was a "kinda quiet guy", and as a child, he was a genius prodigy, who managed to solve a famine in the Middle East and won numerous awards for his discoveries in botany, where he was very knowledgeable, capable of cultivating rare plants like rare species of apples and actually revived an extinct species of flower. Even though, Joachim's creepy and intimidating demeanour alienated everyone around him and he soon became lonely. Even after Dzerve managed to make friends with him to an extent, his slight resentment and jealousy at wondering why somebody like Dzerve managed to be loved while he ended up alone still dwelled within him – these negative feelings were the catalyst for Klaus/Devius corrupting him into one of the first Hellions.

After his transformation, taking upon the moniker of "Gehaburn", the bad parts of Joachim's personality became excessively amplified as his anger and discontent at the world for supposedly rejecting him despite his accomplishments boiled to the surface. No longer holding these feelings in, Joachim lashed out at the world with malicious glee, and yet in spite of his vehement dislike towards Klaus, Joachim was still bound by nature as a Hellion at him, forced to follow his every word – this resentment ran deep within as he hated playing second fiddle to the one whom had overshadowed his accomplishments, wishing to overthrow Devius and become the leader of the Hellions. Deep inside, Joachim was always a budding sociopath, whom originally wished for friends in his child and teenaged years; but later, in his older years, he lost his desire for friendship, seeing it as laughable as his trademark cruel and ill-tempered nature befitting that of a snake bubbled to the surface. This nasty personality of his played a major part in his current role – while Hellions are normally twisted evil parodies of their human hosts, Joachim's hidden dark side ensured that there was nothing that could make him worse, so he managed to devour his own Hellion and remain in control of his actions, fooling others into believing that he was devoured by his Hellion in order to gallivant around and commit numerous atrocities to their faces with them seemingly none the wiser. Even after his transformation, Joachim had a certain charm about him that made him likeable, but it only highlighted his own madness and insanity when the madness was uncovered – driven by feelings of inadequacy and a hatred of others, he is full of envy for his co-workers for being recognized for all of their team's achievements while he was ignored; probably not helping is the fact that Dzerve and Klaus either didn't notice or did notice but didn't do anything about it – definitely in the case of the latter.

After his reincarnation upon Earth Land, his mutation into a dragon, and subsequent return of his memories and the recollection of Devius' orders, Joachim, now the "Absolute Toxicity Dragon, Culebre" changed once more, but this time, only slightly. Taking his snake-like traits to their zenith along with his difficulty in establishing personal relationships, Culebre was perhaps the only dragon to avoid the main pack and instead sauntered off to parts unknown, working on Devius' plan to open a Dimensional Gate and bring him – and Signa – into the current world. Being extremely sharp-tongued, condescending, and slippery like a snake, in spite of his power, Culebre generally avoids combat instead of leaping into the fray as he prefers to plan from behind the scenes, ensuring that everything goes according to keikaku (TL note: keikaku means plan). He is also a calculating trickster who doesn't mind using his own kind for his schemes and cares little for consequences, but even so, when the chips are down, Culebre is also rather fearless as he manages to keep up his playful nature even in the face of warriors whom could destroy him easily such as Ashley Briett and Elucifer Mercury, and in these cases, instead of merely running away, he tends to mock his enemies while explaining how hopeless the chances of them achieving victory against him are. Though he is not as powerful as Devius' other enforcers, Camilla Straights, Chakravartin, and especially Signa, his cleverness makes him very dangerous. Given Culebre's role in the overarching plot of the Sun Trilogy as the mouth of Devius so to speak, and how he manipulates the easily-tempted into progressing his plans, he could be considered similar to the snake whom tempted Adam and Eve in the Bible. Even so, he's considered a small-fry in the grand scheme of things, with nobody ever giving him the respect that he believes he deserves, something that infuriates him endlessly.

Physical Abilities
Immense Physical Capabilities: Dragons are known to be incredibly strong and hard to kill, to the point that they are more or less invincible; not that people actively seek them out to kill them anyway. Dragons are known for their enormous brute strength - they are powerful enough to smash through buildings no matter their construction method or any types of enchantments placed upon them just by charging at them; even capable of overwhelming even ace magicians with relative ease as seen when the swooped down to assault  and ripped him to shreds in an instant; a testament to their size and strength. The body of a dragon is known to be extremely tough- as due to their usually odd proportions; a dragon's body is more like a weapon itself than any individual body parts mostly due to their magic- due to their generally reptilian bodies, their tails function more like an extremely powerful whip that lashes around with abandon, devastating everything that comes into contact with them easily. Each and every step that they take causes an immense ripple of pure power, which, when it makes contact with a solid surface, results in a transference of a large amount of kinetic energy, which is the energy possessed by any moving object into the point of impact to cause a emission of high-pressure wave of pure concussive force known as a shockwave that travels faster than the speed of sound and can propagate through the point of impact, shaking both the medium and anything around it, causing the objects around the point-of-impact to vibrate erratically in an extremely hard and fast wave, which causes other things that the material touches to vibrate too, resulting in a powerful explosion that does even more damage. Also, despite their odd proportions, dragons are known to be surprisingly swift on their (non)-feet, capable of out-speeding a magician who uses speed-enhancing magics such as High Speed and Slowing Magic, flying around at speeds beyond the speed of sound to the point that a dragon can cross the entire distance of, passing over all of the world's continents in nothing but a few hours, while those who stare into the clear azure skies see naught but a blur racing through the heavens, instilling a sense of wonder into the atmosphere. Due to their wings and the velocity produced by kicking off of the ground with their powerful leg/body strength, dragons are also capable of flight at high speeds, their wing-beats stirring up countless gale-force winds as they soar about the atmosphere. Of course, dragons are very durable as well; their scales are so strong that, aside from their own power being turned against them, seemingly no form of Magic with the exception of Dragon Slayer Magic can pierce through them - indeed, their scales have shown that somebody can receive near-fatal lacerations just by touching them, with their durability being greater than to the point of effortlessly surpassing the latter — even if the dragon does not simply turn into their element to evade all sorts of attacks, a dragon is capable of shrugging off all sorts of attacks sent their way including being in the epicenter of the blast of, a magical weapon of mass destruction said to be capable of reducing an entire continent to nothing. Even their general body strength is capable of withstanding and deflecting spells and physical blows that would normally be extremely damaging - their bodies are simply magic-resistant thanks to their scales. A Dragon has an enhanced sense of smell, at least fifty times more sensitive than a dog's; this has been bolstered to the point that a dragon can sniff out lies so they know when somebody is being deceitful. Their eyesight also gives them night vision and they can see from fourty kilometers away without any assistance, whether natural or not.
 * Flight (, Furaito lit. Dragon's Wingbeat): Flight is a natural and permanently activated portion of a dragon's biology; through a constant flapping of their enormous wings, a dragon produces aerodynamic forces facilitating movement through air and other gases, or water and other liquids, moving through an atmosphere or beyond it without direct support from any surface, able to induce various types of aerial locomotion. At any moment, a dragon is capable of ascending to the skies with a single beat of their large wings, producing enough aerodynamic forces in order to facilitate movement as their bodies are lifted off of the ground, instantly accelerating to velocities that shatter the sound barrier which barely gets the chance to increase the dragon's aerodynamic drag and other effects as they approach supersonic speed, producing a multitude of shockwaves that are accompanied by a serial of deafening sonic booms, generate enormous amounts of sound energy that sounds much like an explosion with every flap of their wings. Of course, as one would expect, their wings allow a dragon to travel across rough terrain, moving through areas where flying is the only method of passing through, or even just getting to higher places. The absolute minimum speed that a dragon is capable of moving at while airborne exceeds the speed of sound, reaching supersonic speeds over seven hundred and sixty-eight miles per hour - it's known that a dragon can cross the entire distance of, passing over all of the world's continents in nothing but a few hours, while those who stare into the clear azure skies see naught but a blur racing through the heavens, instilling a sense of wonder into the atmosphere. Due to their wings and the velocity produced by kicking off of the ground with their powerful leg/body strength, dragons are also capable of flight at high speeds, their wing-beats stirring up countless gale-force winds as they soar about the atmosphere. When not using their wings to move through the air, a dragon can also use their wings to give themselves a speed boost when moving along the ground, by using them to propel themselves forward at breakneck speeds; a dragon can also use their wings for defensive and offensive purposes, by using them to attack their foes by twirling around, or swinging them like a whip.

Magical Abilities
Masterful Magical Energy Control: Dragons, as a whole, as the embodiment of "ultimate power", are shown to possess a natural affinity for utilizing both magical energies and eternano in any way that they deem it to be suitable - as long as they are capable of imagining it being done, effectively, the sky is the limit, with their arcane skill resembling the likes of Arc of Embodiment or considered akin to reality warping, a supposedly almighty power that allows the user to create, change, destroy, and even alter the very fabric of reality through nothing but their thoughts. The raw arcane power output of a dragon is truly immense, bordering on being a living a tactical nuclear device to the point that a dragon entering the battlefield in a war prompts a signal for everyone, friend and foe, to get the hell out of dodge. Their Magic Origin is completely different than that of any other races'; indeed, it is referred to as the Factor of the Dragon (竜の因子, Ryū no Inshi); the dragon's origin produces a unique magical power that transcends what could be achieved by normal humans. Normally, a magician's body could be considered a machine which created magical energy, a Dragon's magic origin acts as a factory which created magical energy. It functions as an enormous magic core with tremendous capacity that generates energy independent from their body simply through breathing, and as such, a dragon has an easier time collecting stray eternano in environments with higher concentrations of it such as the area where a vicious battle between others has progressed; thanks to their method of creation, a dragon is said to be in-tune with the essence of magic itself, through their eyes, magic is simply an extension of their willpower. Their body stores energy actively within their soul as an energy pattern that is linked to their body's Factor of the Dragon. This energy powers most of the dragon's magical abilities, giving them an enormous boost in her magical capacity over other races. Because of the Factor of the Dragon, to a dragon there is no difference between simple eternano and their own magical energy as a source of power. They are capable of bringing out the power of their own magic-enhanced attacks to the utmost maximum as well as stunt their enemy's own magical prowess with naught but thoughts. They are capable of drawing in ambient eternano from the atmosphere, and instead of absorbing it into their magical origin, a dragon is able to manipulate the eternano for offensive, defensive, and supportive purposes in any way that the dragon wishes; enabling them to harness their magical power more efficiently and utilize it in a variety of different ways; all of which incorporate the focusing of magic power into certain areas in order to achieve numerous and highly varied effects such as increased attack, defense, and speed, or feeding extra eternano into attacks to give them an enormous boost in power. Even when worn-out in battle, a dragon can continue fighting effectively while still using their magic to their fullest extent; being a juggernaut who, most of the time, is unable to be impeded unless it is via the strongest opponents. The pressure released by their magical energies like a bottomless well from which their energy springs- it never seems to run out, and theoretically, they could fight for extremely long periods of time without rest; it is so great it can be felt from a great distance and it has the tendency to make people perspire in fear, regarded as immeasurable, that any individual that tries to sense the depths of their power will only find themselves lost in its vastness. A dragon's eternano prowess functions as a defense against all kinds of illusions, including Illusion Magic, due to their sheer mastery over it, making them all but immune to everything except the strongest of fabrications; and even then, they are capable of shrugging them off effortlessly. In the case of the strongest dragons, their mastery over the arcane results in them possessing complete immunity to the likes of Memory Control and other manipulation-type magics, including, a non-existent magic that allows the user to dominate the will of a Dragon, effectively making them their subordinate.
 * Ley Line Connection (, Rei Rain Konekushon lit. Dragon's Vein Connection Resonance): Ley Line Connection is an uncategorized "spell" of sorts that's permanently activated but can be turned on and off in accordance to the user's willpower - it's an ability that's exclusive to Dragons and Dragon Slayers, allowing the fighter to tap into the alignments of places of significance in the geography or culture of an area, often including man-made structures known as the leylines, the conduits of supernatural energy that surround the planet. As existences that were born from the dormant leylines reacting with the opposing emotions from the Old World and the resultant surge of power, the dragons and their kin are capable of accessing the Ley lines (, Rei Rain lit. Dragon's Vein), a virtually untapped, raw source of magical power that has filtered through the depths of the earth for years on end- they are alignments between places of magical power; normally, only Dragons and Dragon Slayers can tap into them to gain extra powers whenever they wish, but other beings with immense quantities of magical energies such as the Magnus Magus are able to replicate this feat. The ley lines are in the older sense, ancient, straight trackways in the landscape, or in the newer sense, spiritual and mystical alignments of land forms. Through tapping into the ley lines, the dragon is capable of bending the mystic forces of the world to their will, altering the landscape and climate in accordance to their thoughts and feelings, controlling the environment through the process of terraforming, which is the hypothetical process of deliberately changing the environment of an entire planet, moon, or asteroid to an entirely new environment which the caster deems to be more suitable in regards to the situation at hand in a manner not dissimilar to, with the dragon's movements and actions allowing them to remake surrounding areas however they see fit, modifying the atmosphere, temperature, surface topography or ecology of a world to be similar to the biosphere of Earth or other habitable worlds, in order to make it habitable to other species. The effects produced by their connection to the Ley lines forcibly alters the geography and environment of the lands deliberately through Ley line manipulation vary from creating new paths, drying up rivers to create more terrain, freezing enemies or reducing the movement of those stuck on the ground and increasing the movements of those who are airborne- at it strongest form, by utilizing their power, the caster is capable of terraforming an entire mountain range and causing lava to erupt forth from beneath the earth, which, of course, can melt damn near everything that it comes into contact with. By manipulating the very geography of the ground itself, the user of the Ley lines can alter the landscape by compressing the land, while given the ability to purposely send certain things or people to certain locations, and in a similar manner to Terrain Effect Magic, the caster is able to change any type of terrain to any other type, for example turn a mountain into a sea, desert to jungle, hill into a lake, etc, shaping the environment in accordance to their imagination as if they were utilizing Molding Magic. Areas that can be manipulated by Ley line manipulation are highlighted by glowing orbs of various colours on the battlefield; these orbs are only visible to dragonkind. Culebre himself normally utilizes the Ley lines as a last resort in order to take his opponents by surprise by ripping them open and changing the terrain to his exact liking constantly with his ultimate attack.

Poison Dragon Slayer Magic
Poison Dragon Slayer Magic (毒の滅竜魔法 Doku no Metsuryū Mahō) is a Caster Magic, Lost Magic, Slayer Magic, and lastly as well as most obviously, a Dragon Slayer Magic which is focused upon the transformation of the physiology of the caster's body into a dragon, which are extremely powerful and flight-capable legendary creatures that are a strange mixture between serpentine, reptilian and avian traits that live in ; resulting in Poison Dragon Slayer Magic revolving around the generation, manipulation, and consumption of the element of poison, which are substances that cause disturbances in organisms, usually by chemical reaction or other activity on the molecular scale, when an organism absorbs a sufficient quantity as well as a variety of poisonous substances that injure the health or destroys life when absorbed into the system, meaning that Poison Dragon Slayer Magic does not solely revolve around poison, but also toxins, a poison produced by an organism such as a plant, fungus, animal) it is especially used in medicine in reference to disease-causing bacterial secretions, and venom, referring to the poisons secreted by certain animals, usually injected by bite or sting.

As briefly mentioned above, Dragon Slayer Magic is a Caster Magic, Lost Magic, and last but not least, a Slayer Magic that allows its users to transform the physiology of their body into those of a dragon, a species of legendary creatures whom are oftentimes regarded as the strongest of all monsters with immeasurable power and intelligence dwelling within their bodies – dragons can be said to be less of an organic creature themselves but rather, an embodiment of the greatest power of all, and as such, these beings are revered and feared by all whom are knowledgeable of their existence, the mere mention of them causing shockwaves that radiate throughout the lands, magicians of all ranks and walks of life quivering at their name. More importantly, as "ultimate power made physical", they would need an "ultimate magic" to suit their very nature as power manifested in the mortal plane of existence; something that would be far above most magicians in the era that they made their mark on mankind. They could be thought of as "Elemental Magic made manifest and brought to its absolute zenith", though while a personification of the strongest power imaginable; the chains known as a "mortal body" that bind them to the dimension referred as do not hinder their performance in battle in the slightest – in fact, their mortality and physical form allow them to utilize their unique Magic Origin which is referred to as the Factor of the Dragon (竜の因子, Ryū no Inshi); indeed, the dragon's origin produces a unique magical power that transcends what could be achieved by normal humans. Normally, a magician's body could be considered a machine which created magical energy, a Dragon's magic origin acts as living power plant which created magical energy, serving the purpose of an enormous magic core with tremendous capacity that generates all sorts of elemental energy that's independent from their body through the simple act of breathing, capable of serving as a power source to power countless appliances – all this works in conjunction alongside the perks that their biology normally gives them; and through application of magical manipulation, grants them the ability to reinforce the sheer power of their own body with their signature element which is assigned to them as birth; generating limitless quantities of their element with an absolute dominance over said element, bestowing upon the wielder of Dragon Slayer Magic fearsome power in the heat of combat. In this case, the dragon who taught the wielder was a Poison Dragon, which granted them the ability to manipulate, generate, and absorb all sorts of poisons in a similar manner to itself.

However from what is known, all forms of poison-based dragons were wiped out during the, meaning that in order to harness the power of Poison Dragon Slayer Magic, requires a Ryū no Lacrima (, Ryū no Rakurima lit. Magic Crystal of Dragons); an rare and extremely expensive Lacrima which is a magic crystalline substance found in both and  that gives individuals artificial Dragon Slayer Magic to be implanted within their body, thus making any potential inheritor a Second Generation Dragon Slayer Magic (二世滅竜魔法, Nisei Metsuryū Mahō) by default. In spite of this, it seems that Culebre is the very last Poison Dragon left in Earth Land, and as such, he has access to the true power of Poison Dragon Slayer Magic. Thus, in the case of the Poison Dragon Slayer Magic when used by a dragon, the Absolute Toxicity Dragon takes blatant advantage of the fact that their mortality and physical form enables them to utilize their unique draconic Magic Origin alongside the perks that their biology normally bestows upon them; their biological structure has been perfectly attuned to how their Factor of the Dragon functions; more specifically, since with every breath, the Absolute Toxicity Dragon generates energy independent from their body; which, through application of magical manipulation, grants the wielder of Poison Dragon Slayer Magic the ability to reinforce the sheer power of their own body with their signature element. But of course, no matter whom is utilizing this amazing power, when inducing the activation process for Poison Dragon Slayer Magic and thereby performing the signature toxigenesis power of this magic, the wielder focuses intently, pulsing the immense quantities of arcane energy that are dwelling within their Factor of the Dragon outwards as to scatter throughout the atmosphere and integrate with the ambient eternano particles saturated within the vicinity, invoking the usual fusion of magical energy and eternano so universal in regards to the art of spellcasting – however, while releasing their magical energy, the caster harnesses mental commands and direction in order to bestow upon their energies a rather sinister traits, causing their energy to take upon a stupendously high level of toxicity as it transmogrifies its state of existence into a scarlet and raven liquid form – though this can also change into a gaseous state if the wielder of Poison Dragon Slayer Magic deems it to be suitable.

Despite the boons bestowed upon the user as mentioned in the base description for all forms of this magic, the traits such as dramatically enhanced physical prowess and senses can be said to simply be side-effects of having the physiology of a dragon; indeed, the greatest ability of a wielder of Poison Dragon Slayer Magic is also its signature power – calling upon the assets of a dragon even if their bodily structure isn't one-hundred-percent the same as the beings from which this magic originated, the caster is capable of inducing a metamorphosis of their body structure as to take upon traits of a dragon instantaneously which is done in conjunction with the activation sequence of their poison, bestowing upon the user of Photon Dragon Slayer Magic; draconic lungs and enhanced vocal folds that are capable of spewing poison in the form of innumerous storms of poison needles, rigid plates known as scales that grow out of their skin which are laced with poisonous energies as to provide protection against poison, and fierce claws and nails which are enshrouded with poison, specifically attuned to dealing incredible amounts of damage – all of this combined, results in the physiology of a Dragon Slayer transforming their entire existence into that of a make-shift weapon whose ownership is unique to them and them alone, wielding the element of poison harnessed by their dragon and passed down to them alongside the natural physical superiority of a dragon in combat, utilizing offensive ability, stamina, and vitality, to transmogrify themselves into the greatest weapon of all, thus dramatically increasing the damage inflicted upon anything that they come into contact with using the sheer force of their strikes in all ranges – however, as one may have suspected, close-combat is where Dragon Slayer Magic usually shines thanks to the overwhelming physical might of a dragon, as the magic massively bolsters the power of their unarmed blows with the user unleashing powerful close-range strikes that are empowered with poison as the wielder of Poison Dragon Slayer Magic is commonly seen producing poison from their very existence, before shaping it mentally and setting it upon their enemies to inflict maximum damage with ease. Effectively, this grants the user of Poison Dragon Slayer Magic the ability to manipulate, modify, consume, and generate from their body poison, venom, and toxins to their fullest extent; they have absolute dominance over anything considered to be classified under the broad concept of "poison" and everything related to and dwelling within it.

As with all forms of Dragon Slayer Magic, the "element" that's produced by Poison Dragon Slayer Magic is an inherent part of their fighting style, with the wielder of this magic being capable of releasing enormous quantities of poison in accordance with their willpower – however, something Poison Dragon Slayer Magic possesses as a "one-up" over most other versions of Dragon Slayer Magic is that even when the caster isn't visibly manifesting poison around themselves, these terrible toxins are directly integrated into their very existence; indeed, just like zootoxins, which are a form of toxin secreted by an animal for the purpose of causing harm to another of various reptiles and insects, highly corrosive poison is contained within every inch of the wielder of Poison Dragon Slayer Magic from the very moment of learning the magic, constantly active within their claws, their fangs, their tongue, the blood of a wielder of Poison Dragon Slayer Magic, and their tears – each and every inch of their body is coated in and/or is coated into the poison inherent to this form of Dragon Slayer Magic, being infused within the biology of the user of this Slayer Magic. Thus, any opponent unfortunate enough to face the wielder of Poison Dragon Slayer Magic must be extremely wary as even brushing up against the user of this magic would result in them undergoing a highly advanced form of poisoning, thus immediately deciding the outcome of the battle if not treated with a high level of Healing Magic quickly. When the poison generated through this magic is made manifest into the mortal realm, it seems to be tangible and can thus be used as an effective blunt weapon, inflicting physical damage to foes while at the same time infecting them. The poison produced by Poison Dragon Slayer Magic starts off by slowly stealing the movement from the victims' body away, before subsequently killing them- one touch from Poison Dragon Slayer Magic will decay and utterly destroy everything in the path of the wielder; however, the poison can also act after a given amount of time. When an opponent is poisoned by the toxic energies of Poison Dragon Slayer Magic, their Magic Origin will take a sharp nosedive in effectiveness and potency- their Magic Origin's ability to absorb eternano from the atmosphere will be lessened, as the poison begins to affect their body, with their bloodstream and several organs, including said origin, beginning to malfunction. In any case, the corrosive nature of the magic has some rather complicated math behind it (hooray for math); the target, upon being poisoned, will receive damage and lose one sixteenth of their stamina as well- this will increase by yet another sixteenth every five minutes or if the wielder of Poison Dragon Slayer Magic lands another successful attack. If the target is struck with another energy draining ability, then the damage inflicted by the magic will increase by one eighth in addition to the amount siphoned. If the target heals, thus removing the poison from their body, and is unfortunate enough to get poisoned by the magic once more, the damage taken will carry on from where it was before the target healed.

Unlike the superficial poisons of any other poison-based skills such as Poison Magic and Poison-Make, the poison generated by Poison Dragon Slayer Magic is extremely efficient in addition to being able to be manifested on any level on the toxicity class, acting as a fast-acting poison which is capable of inflicting many painful effects upon the victim, such as intense headaches, nausea, fever, sickness, muscle spasms, and the ultimate deterioration of the foe's bodily functions; meaning that if one of the dragon's attacks doesn't kill the foe, the effects would, as their body was violently dismantled, piece by piece, causing the foe to suffer an agonizing death; and then their corpse would be disintegrated by the ferocity that the poison possessed. Not only this, the toxins released by this form of poison-manipulation magic are known to be able to control all diseases, viruses, bacteria and infectious agent and utilize them in any way the wielder of Poison Dragon Slayer Magic wishes, including their severity, contagiousness, methods of spreading, etc. A user can control the organisms that spread diseases, including germs, bacteria, virus or other pathogen on a cellular level, including bacteriophages, microorganisms, retroviruses, cells that abnormally grow to make cancerous tumors and cysts, and pathogens that produce genetic mutations, as well as mimic the traits of any sort of disease the wielder of Poison Dragon Slayer Magic wishes. Of course, continuing onwards, the user is able to shift the traits of the poison as produced by their magic even further to become a corrosive substance, manipulating the corrosiveness of said acid, the causticity, where and how the acid affects the object, how much fumes it releases and so on; when the poison of Poison Dragon Slayer Magic takes upon acidic properties, it becomes exceptionally powerful to the point that it is capable of burning through anything that's unfortunate enough to stand in the way of the user, melting alloys and both organic and inorganic structures with frightening ease – as one may have gathered from the paragraph just described, the wielder of Poison Dragon Slayer Magic is capable of changing the materials' elemental makeup- as long as it has some traces of poison held within it, the possibilities are endless, both in what the user of this magic is capable of, and how much pain their enemies will be in as they enable their magic to run wild upon them, showing Poison Dragon Slayer Magic to be deceptively malleable and adaptable to the situation at hand.

As with all forms of Dragon Slayer Magic, Poison Dragon Slayer Magic has virtually unlimited customization options in regards to the element formed through simple magical manipulation and reinforced through the power of a dragon – the colour of the poisonous substances produced by the magic is able to be altered freely, its properties which aren't limited to but include temperature, the smell that it emits, its taste, and overall "feel" is capable of being modified to the user's liking for countless different effects and powers, more often than not being attuned to the user's own personality and ambitions; the type of damage that the poison inflicts upon anything that it comes into contact with is able to be changed at will; in its normal state, Poison Dragon Slayer Magic seems to have a "blunt" effect to it, seemingly damage that invokes the sensation of a sledgehammer alongside the user's burning ambition given a corporal form in their element; like all Slayer Magics, the user's element is much tougher than any other example of it; in the case of the user, the poisonous substances which are produced by Poison Dragon Slayer Magic is stronger than normal poisons, capable of shrugging off anything thrown their way, enabling the user to overwhelm other forms of poison, even smothering weaker poisons in their way. Of course, as the highest form of elemental manipulation around, the wielder of Poison Dragon Slayer Magic is capable of harnessing their magic in any manner that they deem to be suitable, commonly changing between offensive, defensive, evasive, or supplementary potencies in accordance to the situation at hand; but generally, as long as the Dragon Slayer is able to imagine these incredible photons being used in a particular manner and it doesn't break the laws of physics or conflict with any established limitations, then the sky is the limit, more or less. As per the nature of Slayer Magic, a Dragon Slayer is immune to the effects of their own element that encompasses any form of poison-related power, and in this case, the wielder of Poison Dragon Slayer Magic can consume external sources of poison to replenish their strength, both stamina-wise and magic-wise. They are also naturally immune to the effects of their own poison that came from both their own person and to those from other sources, but must consume it through their mouths if they are to actually absorb it into their bodies; while they can't consume the poison when produced by themselves, it should be taken into consideration that Poison Dragon Slayer Magic also bestows upon the wielder immunity to effects related to the poison as well such as the inability to be affected by poisonous meals and the like.

Obviously, Poison Dragon Slayer Magic is the main magic of the Absolute Toxicity Dragon, Culebre, being his primary method of combat, and it was said that Culebre was one of the first of dragonkind to unlock the power of his Dragon Slayer Magic at the beginning of magic, alongside Ashur and Níðhöggr. What sets Culebre aside from ordinary wielders of Poison Dragon Slayer Magic and Poison Dragons in general is that unlike other versions of Poison Dragon Slayer Magic, Culebre has the ability to devour his own poisons- or rather, while he doesn't have the ability to consume the poisons generated by his magic, a strange part of the dragon's biology is that regardless of whether or not he uses magic or not, after he has taken enough damage, the yellow orbs upon his shoulders and knees will start to flash, at which point, they begin to leak a golden poison with undefined properties known as Predator Venom (プレデター・ベノム, Puredetā Benomu); however, while not much is known about it, what it can do is melt anything that they come into contact with; but more importantly, Dragon Slayer Magic wise, Culebre is capable of consuming these poisons as they are not a part of his magic, allowing him to restore his own health, both stamina and magic-wise- this means that a battle against the Absolute Toxicity Dragon would be near impossible to win unless the other person involved was a dragon, as Culebre would simply bleed Predator Venom after taking enough damage and consume it to return to top form- repeat until the enemy gives up or loses. In the heat of battle, befitting his motif of a snake, his fighting style resembles one – fast, sneaky, and poisonous. Taking this resemblance even further, his poisons often take the form of snake-like projectiles that race towards his opponent and coil around them in order to restrict their movement, as well as his ability to remain hidden until it's too late and the surprising nature of his attacks. Despite his formidable fighting abilities and impressive magic, Culebre does not like taking foes head on and prefers to flee from most battles and lets his lackeys do his dirty work for him.

Basic Spells

 * Fel Erga (, Feru Eruga lit. Poison Dragon's Roar): Fel Erga is the hyperresonance ability of a dragon, attuned to the element of poison- as such, it works best with Poison Dragon Slayer Magic. When performing Fel Erga, Culebre utilizes his enhanced lung capacity in order to gather and condense ambient eternano from within the atmosphere and store it momentarily within his mouth- from here, Culebre attunes the eternano gathered by merging them with his energy in order to induce the usual fusion to being power into the current realm; this results in the Absolute Toxicity Dragon utilizing his magical energy in order to bestow upon his energies a rather sinister set of traits, causing it to take upon a high amount of toxicity as it transforms its state of existence into a scarlet and raven liquid form. Once this is done, in order to unleash the magical energy, Culebre utilizes the Dragon Cords (竜帯, Ryūtai), a dragon's equivalent of vocal cords which produce a louder and harsher sound while amplifying anything emitted from his mouth tremendously, resulting in a massive blast of energy spewing forth from his mouth towards the target; in the case of Fel Erga, which, of course, as both of its names would suggest, is based around poison, this has the effect of the Dragon's Roar being unleashed as a positively enormous torrent of deadly, poisonous stream in the a hurricane-like manner, aimed towards whoever would be foolish enough to stand in his way. The middle of the hurricane is hollow; this allows the poison to slice the opponent. Should the target dodge, the force of the power generated would knock them back, if not wound them and can be used as a shield against point-black attacks. When it strikes, it grinds into the opponent with extreme force, striking the target multiple times simultaneously, while injecting a lethal virus into the opponent's bloodstream that slowly, but surely weakens them while removing their senses one by one, restricting their movements, destroying their touches and tastes, and blinding them, before ultimately killing them. The curving aspect of this spell makes the hurricane of poison a gigantic heat-seeking missile, but instead of locking on to heat, it targets whatever enemy they have; making it impossible to avoid or escape from—a certain hit is an inevitability, giving the opponents little to no chance to escape unless it is physically impossible to harm them or a serious obstruction is in the way.
 * Poison Dragon's Serial Fangs (毒竜の連牙, Dokuryū no Renga): Poison Dragon's Serial Fangs is a special Poison Dragon Slayer Magic spell that only Culebre would ever think of creating- instead of them being resigned to separate spells, Poison Dragon's Serial Fangs is a "Combination Spell" in a literal sense; it is a merging of, , , and - this deadly quartet of spells has been merged into a single powerful close-range attack, the area-of-effect of which can be extended as well in order to cover a maximum range of two kilometers. In any case, when performing Poison Dragon's Serial Fangs, Culebre utilizes his magical energy in order to bestow upon his energies a rather sinister set of traits, causing it to take upon a high amount of toxicity as it transforms its state of existence into a scarlet and raven liquid form which he uses to coat his arms up until the wrist area in this black and red poison. Once this minor process has been completed, the evil dragon can shape these poisons in any way that he wishes in order to attack, whether it be by moving his arms forwards in a cross in order to release two massive waves shaped like fangs, or a single large-fanged snake head which can bite anything to nullify its kinetic energy- Culebre can also unleash it by attacking with a poisonous open-hand, striking with his finger-tips from which poison mist trails, or by grabbing hold of his target with one hand and releasing a burst of poison from it at point-blank range. In any case, these forms each do the same amount of fixed damage to the target- which is actually quite a bit, for one. Of course, given the nature of the magic, each strike can poison the target upon contact. The poison released by this attack starts off by slowly stealing the movement from the victims' body away; decaying all that it touches; however, the poison can also act after a given amount of time. When an opponent is poisoned by this attack, their Magic Origin will take a sharp nosedive in effectiveness and potency- their Magic Origin's ability to absorb eternano from the atmosphere will be lessened, as the poison begins to affect their body, with their bloodstream and several organs, including said origin, beginning to malfunction. In any case, Poison Dragon's Serial Fangs' corrosive nature has some rather complicated math behind it (hooray for math); the target, upon being poisoned, will receive damage and lose one sixteenth of their stamina as well- this will increase by yet another sixteenth every five minutes or if the wyvern lands another successful attack. If the target is struck with another energy draining ability, then the damage inflicted by this attack will increase by one eighth in addition to the amount siphoned. If the target heals, thus removing the poison from their body, and is unfortunate enough to get poisoned by the attack once more, the damage taken will carry on from where it was before the target healed.

Advanced Spells
Dragon Slayer's Secret Art (滅竜奥義, Metsuryū Ōgi): The strongest techniques of a Dragon Slayer. What should be noted, is that the Absolute Toxicity Dragon's bog-standard Dragon Slayer's Secret Arts are about as powerful as anyone else's Dragon Slayer's Ultimate Arts (滅竜極義, Metsuryū Gokugi) and Dragon Slayer's Forbidden Arts (滅竜禁義, Metsuryū Kingi); additionally, Culebre's Secret Art prefix, Mefitas (, Mefitasu lit. Life-Slaying Poison), is the name of the Roman god of 'poisonous vapors from the earth', believed to be responsible for the foul gasses of sulfur that would rise from certain grounds and swamps.
 * WyrmSoulCulebreOugi.pngMefitas: Abrade Venom (, Mefitasu: Abureido Benomu lit. Life-Slaying Poison: Hell's Judgment): Mefitas: Abrade Venom is a Poison Dragon Slayer Magic spell which is one of the Dragon Slayer's Secret Arts, the strongest techniques of a Dragon Slayer – in the case of Mefitas: Abrade Venom, it involves the caster launching innumerable spheres of highly corrosive and venomous poison towards their enemy. In any case, when performing Mefitas: Abrade Venom, the wielder of Poison Dragon Slayer Magic focuses intently, pulsing the immense quantities of arcane energy that are dwelling within their Factor of the Dragon outwards as to scatter throughout the atmosphere and integrate with the ambient eternano particles saturated within the vicinity, invoking the usual fusion of magical energy and eternano so universal in regards to the art of spellcasting – however, while releasing their magical energy, the caster harnesses mental commands and direction in order to bestow upon their energies a rather sinister traits, causing their energy to take upon a stupendously high level of toxicity as it transmogrifies its state of existence into a scarlet and raven liquid form – this poison now manifested fully, the wielder of Poison Dragon Slayer Magic induces a process not dissimilar to Shape Transformation as they flare their Magical Aura up to its fullest extent, their slitted pupils shining an illustrious yet menacing emerald as the so-called boosters attached to their back jut upwards, energies flowing outwards as to force their arcane aura to take upon the form of an innumerous quantity of pulsating emerald spheres with rings of crimson centered around them, whirling at incredible velocities; the actions of these orbs seem to cause a momentary dislocation in the continuum of spacetime with the sheer quantity of energy generated by this simple action – this is the meat and bones of Mefitas: Abrade Venom taking effect. With a single command, the wielder of Poison Dragon Slayer Magic launches the myriad of orbs towards their opponent, racing forward towards the caster's opponent. As they dart throughout the atmosphere, the orbs of poison induce a form of corrosion upon almost anything that they come into contact with; creating a wave of poison that circle the spheres which rush across the skies and poisons even the air itself, dealing extra damage; charging forward with high speeds which are known to be immensely fast, closing distances up to five thousand kilometers in the blink of an eye, and yet despite their size, the orbs of poison can turn and stop on a dime with no unnecessary movements displayed- it is said that the group of poisonous orbs can out-fly a user of High Speed, Slowing Magic, and even Flight Magic; reflecting the attack back at the user's opponent with the added power of the orb's rush; they are touted to chase their foes to the ends of the earth, no matter where the foe is standing, even if they possessed high speed, as they would catch their foe eventually. The poisonous orbs can move at impossible angles that always manage to reach its target; they will always change their path around any obstacles or pierce through any wall in order to reach their target, and as they move though the atmosphere, they gather and condense stray magical particles upon their forms to increase in speed. Upon impact, the countless poisonous orbs seem to violently release the compacted energies that compose their existence, resulting in the creation of a myriad of noticeable propagating disturbances known as a shockwave which travels across the ground in a manner that causes it to fan outwards, damaging anything in its path and dealing "splash" damage of a sort as opponents near the user's target will not only also be struck by the sheer volatility of the explosion, but the shockwave will more often than not just knock them straight off their feat, leaving them open to further attacks; even at its weakest point of power, the explosion deals a rather noticeable amount of damage to the vicinity, and it is capable of vaporizing a solid rock wall in a single detonation. Additionally, the rapid accumulation and projection of particles within the atmosphere as the result of a high explosives detonation results in various fragments of structures being propelled in countless directions in various velocities and angles, often travelling innumerous amounts of distances, often carrying enough energy to initiate other surrounding high explosive items, injure or kill nearby people and damage almost any structure in the vicinity.

Trivia

 * Culebre is a giant winged serpent-dragon of the Asturian and Cantabrian mythology that lives in a cave, guard treasures and keeps xanas as prisoners. Although they are immortal, they grow old as the time goes by and their scales become thick and impenetrable, and bat wings grow in their bodies. They don't usually move, and when they do it, it is in order to eat cattle and people.
 * As the previous Ouroboros Hellion, it's unknown what Joachim's Hellion form looked like, but given that Hellion forms look similar no matter the host albeit with some colour deviations, it can be assumed that his Armourized state was roughly similar to Sion's.
