Cobra (Copycat)

 Cobra (コブラ Kobura), whose real name is Erik (エリック Erikku), is a former member of the now-disbanded Oración Seis, a Dark Guild composed of six powerful Mages. He, along with the other Oración Seis members, sought to find Nirvana, a destructive Magic that was sealed long ago. After the events of Grand Magic Games and Opening of Eclipse, Cobra was set free from his prison. In attempt to free his former allies, Cobra began his own adventure. While he became much stronger than he was, he eventually became a new member of Dragon Soul guild. While he said, that conquering the world with Nirvana plan was failed, he want to try it again with Dragon Slayers, but his real motives and his attempts of saving his comrades are remaining unknown.

Appearance
Cobra is a slim man of average height with tanned skin and spiky, upward-styled crimson hair; aside from a tuft covering his forehead and two bangs framing his face. He’s noted to have snake-like features, with slanted eyes similar to Natsu Dragneel’s, a rather flat nose, and prominent canine teeth. Under his clothes, he has a very muscular body as a result of being trained from the very time he was a slave and came under Brain's custody. After events of Nirvana, Cobra has a great burning scar over the half of his back and a scar from a bullet on his right shoulder, thanks to the Brain's betrayal. Also, after being imprisoned for seven years, Cobra gained a scar over his right eye, saying, that it's his sacrifice in order to attain new powers (the real reason of his scar appearing is unknown). His ears also became noticeably pointed (heavily hinted to his hearing powers upgrade).

At the time of Nirvana accident, Cobra's outfit consisted of an elaborated whitish coat with purple inner lining and cuffs intricately decorated by silver-colored motifs, and many studs lined up the chest, the high collar and the sleeves, which have armbands seemingly made of metal around them above Cobra's elbows. Below it, Cobra wears a dark shirt, and he also sports a pair of crimson leather pants held up by a studded belt, with more similar belts circling diagonally the upper parts of his legs, and simple brown shoes.

When he made an attempt to runaway from his prison with his allies from Oracion Seis, and when he was set free after events of Grand Magic Games, Cobra changed his way of clothing. He was seen wearing gloom red-colored free long kimono with silver-colored edges, black pants and simple black boots. Over the kimono, Cobra wears a long light-colored cape with dark blue-colored shoulders on it, with the same silver-colored edges which are seen on the kimono. His lower part of legs are protected with armor on it.

When he appeared at the Opening of Eclipse and was set free, Cobra was wearing the clothes which are very similar to his pre-timeskip attire. He wears a black T-shirt with some strange end on it with flame-like pattern, dark-colored pants with scale-like pattern, belt and usual boots. Above his T-shirt, Cobra wears short red-colored jacket with zipper and silver-colored edges. He also wears a white coat with forest-colored fur and gray-colored stripes on it and some dark-colored gloves. When he entered the Dragon Soul Guild, he continued to wear this new outfit.

Being an artificial Dragon Slayer, when Cobra makes use of his Dragon Slayer Magic, the tops of his hands and forearms become covered in crimson Dragon scales, while the bottoms are milky and smooth. His hands also gain sharp, pointed, claws. As it seen at the events of Opening of Eclipse, his poison also change it colors from deep-red to more light-red or dark-purple color.

Personality
As a former Dark Mage, Cobra has a typical bad guy-like personality. When he was a part of the Oración Seis, Cobra was confident and enjoyed seeing his opponents suffer, just like his comrades. Cobra believed that Second Generation Dragon Slayers are superior to First Generation Dragon Slayers, and even found their existence questionable, as Dragons are believed to be extinct, and therefore found it ridiculous that people such as Natsu were taught their Magic by nonexistent beings. But, after the events of Eclipse Opening, Cobra has changed his opinion about it, thinking, that "in this damned world is all possible". Alongside, he was thinking about his capabilities as the Dragon Slayer, because he was the one, who couldn't kill and even seriously harm the dragon itself with the other six Dragon Slayers from Fairy Tail and Sabertooth. But, Cobra is also quite easy-going, as he was able to laugh at a joke during his battle with Natsu.

Cobra harbors great affection towards his snake Cubellios, considering her to be his greatest friend from the time he was a slave in the Heaven Tower under the iron hand of tiranic Jellal, and being willing to dedicate his prayer to hear her voice, which in itself is impossible, even for someone like Cobra, who has exceptional hearing. However, he didn't know that Kinana is Cubellios herself right up to the events of his jail break and appearing of Reborn Oración Seis.

In X791, at the time of his re-appearing, Cobra had a more quiet, angry, and hostile personality. He frequently belittled Erza Scarlet and the Fairy Tail Guild for their faith in friendship. He also experienced inner turmoil regarding the Reborn Oración Seis, and how much they had to give up; he believed that Fairy Tail is undeserving. It is not until he is defeated by Erza and he sees Kinana again that Cobra forgoes his forsaking of friendship and with that, he understands, that Kinana indeed his friend Cubellios.

After some times passed and events of Grand Magic Games took a very dangerous side, as the dragons had appeared from the Eslipse Gate, by the Jellal's request, Lahar and Doranbolt set free Cobra in order to defeat Dragons. Cobra has displayed much more easy-going personality of himself at that time, as he again received the opportunity to hear all the voices and Kinana's too. He even saved the Blue Pegasus Guild and say to them to not interrupt his fight and disturb him. Even if he returned to the jail after the battle with dragons, it seems, that he indeed enjoyed the battle alongside the other Dragon Slayers.

As he finally was set free, Cobra wanted to save his comrades again, but he understood, that he must become more powerful in this attempt. After his trainings and adventures for three or four months, Cobra eventually found out, that Dragon Soul Guild is existed. When he came to them, he displayed a very calm personality, showing himself as the man, that will never lie as he knows every thought in every person's mind. He is less agressive now and never goes to bellitle or underestimate his enemy. Also, it seems, that he can enjoy some companies, even if he prefers to be a lone wolf.

But, in battle, Cobra is drastically changes. His agressive nature returns, as he can easily show his killing intent, which became even more stronger and frightening compared to past times. He tries to not lose his coldness, as he is displayed as a cold-blooded warrior, capable of killing his target without hesitation.

History
Jellal Fernandes enslaved Cobra as a child until Brain arrived at the Tower of Heaven and took Cobra and four other enslaved children to become members of his own guild, all with Jellal's permission. Cobra soon became a member of the Oración Seis, one of the three most powerful Dark Guilds, and, much like his guildmates, began to seek out the lost, destructive Magic that is Nirvana.

Fanon History
Coming soon...

Natural Abilities
Enhanced Durability: Cobra had proven himself to be a very durable fighter. In his battle with Natsu, he has been seen enduring a barrage of powerful melee strikes from the Fire Dragon Slayer, enhanced by respective magic, without receiving major injuries and continuing the battle afterwards as if nothing had happened. He also survived a fall of several meters which saw him coming crashing down to the ground, and stood back on his feet moments after. After more than seven and half years passed, Cobra is shown to have even bigger level of durability, as he was capable to fight a real dragon alone, even he wasn't the winner of that fight. Moreover, while he received moderate injuries from dragon's attacks, Cobra was able to make some strong moves and attacks to dragon too.

Enhanced Strength: Cobra had displayed a high degree of strength: he was shown to be capable of effortlessly sending Natsu flying several meters away with seemingly casual attacks on two different occasions, the first with a simple slap, and the second with a knee. Beside it, Cobra was able to effortlessly defeat Erza Scarlet in their first battle as he even poisoned the S-class Mage. Cobra has also shown to be able, with his Dragon Slayer Magic, to completely crush the Rock Dragon's scales with a mere punch, while it is known, that dragon's skin is very durable and mostly unbreakable.

Master Hand to Hand Combatant: Cobra has been shown to be proficient in unarmed combat, employing fluent motions to rapidly strike his opponents. His hand-to-hand skills are complemented by a high degree of agility, with Cobra being capable of perfectly maneuvering and dodging attacks while remaining on Cubellios' back. The power of his strikes is greatly increased when he makes use of his Dragon Slayer Magic, which allows him to also poison his opponents on contact. It is also was stated, that every Mage from Oracion Seis is able to destroy entire guild on their own. After the timeskip and some trainings after that, Cobra now is a master of unarmed combat, as he was able to merely defeat Erza Scarlet by the time he looked aside for Kinana and destroys several Dark Guilds alone. The reason why he did this is remain unknown.

Magic Abilities
Immence Magical Power: To utilize Magic, a Mage must use his/her Magic Power (魔力, Maryoku) in their body. Magic Power is the source of Power for all Mages and it's composed of Eternano (魔子 (エーテルナノ), Ēterunano lit. Magic Particles). Eternano dwells inside all living organisms and throughout the atmosphere. Every Mage has a container inside their body, that determines the limits of their Magic Power alongside being the source, from which a magician derives the power he needs - their own body's Magic Origin (魔原, Magen), a special organ that is located within the body of a magician, that absorbs eternano and bunches it up into clusters, which is processed into magical power. Other source, from which the Mage derives the power he needs is the atmosphere. Usually, the amount of magical power is depended from Mage's physical body, as S-class Mages and Saint Wizards can have almost endless magical reserves. In general, all Mages have their iwn limits. If their body's case becomes empty, eternano will come from the atmosphere and enters the Mage's body and after a while, their Magic Power is restored. As a very strong Dark Mage and a Dragon Slayer, Cobra possess a great level of his magical power alongside the great reserves. He can easily release his magic aura with his terrific killing intent, use powerful spells, etc. The control, which Cobra has over his abilities now is much stronger, as he always has several trump cards upon his sleeves.
 * Eternano and Magic Power Manipulations: Once the user has mastered their own magic, they are capable of drawing in ambient eternano from the atmosphere, and instead of absorbing it into their magical origin, they are able to manipulate the eternano for offensive, defensive, and supportive purposes in any way that they wish. Along with that, some Mages can master their magic power manipulation, a method, which used by some magicians to control their own magic power for a large variety of different purposes, generally, which are the same as for Eternano manipulation, ranging from offensive and defensive, to physical or magical upgrades. After the events of Nirvana, Cobra spent almost all of his time in the jail and after he was set free, to master both of these Manipulations. Cobra eventually made it, as he became a master of both of his Magics. Now, he easily can turn off his hearing ability, which he had as a passive ability. Above that, as it was seen when he was fighting the Rock Dragon, he used his Dragon Slayer Magic without entering the Dragon Force state, which also hints, that Second Generation Dragon Slayer can attain the better control of their lacrima powers with some time and hard trainings.
 * Magical Aura (魔力の霊気 Maryoku no Reiki; lit. Aura of Magical Power): Magical Aura is a common term given to the exertion of magical energy into a form outside of the user's body that isn't used in the formation of spells. It has been demonstrated by various mages of varying potency, and is a common means of intimidation. A magical aura is created when the body's container of Eternano particles exceeds the limits of what it contains, or is purposefully released by the user. Upon doing so, the magical energy surges around the body and is exerted outwards in the form of an aura, which holds considerable pressure surrounding it. Depending on the level of magical power one possesses and the control behind it, it can be used as a means to intimidate another individual, or as a preparation for a powerful spell. A single magical aura can have a wide variety of effects dependent on the power an individual exerts, which will be outlined in the following sections. Cobra, as former Dark Mage, that was a part of Balam Alliance, was shown to have great magic powers. Now, as he didn's lost his powers, he easily can unleash a great magical aura, an ability, which is demonstrated solely by S-Class mages or above in potency. When exerted, the S-Class aura takes the form of an overwhelming level of pressure that surrounds the user in a color that best represents their personality, in Cobra's case, his aura takes dark-red & black colors, hinting to his origin as a Dragon Slayer. Also, due to the nature of his magical abilities, he also displays his great killing intent with his aura, a trait, which mostly frighten his opponents momentaly. It generally encompasses them in a certain radius, and demonstrates a level of strength that leaves most mages unable to react to it unless they've had continual exposure or exert an aura of similar potency. However, the problem with this aura is that if it used continuously, it can tire an individual. Though considering most S-Class' level of magical power, this is rarely the case. The variety of effects achieved by this aura are noted to be quite high, as it can take the form of different shapes and can be used to repel magical and physical assaults alike.
 * Second Origin Activation (二番原解放, Nibangen Kaihō): Second Origin is a force known as the "second container" of magical energy in an individual. This container exists due to the mage in question constantly, and passively, absorbing a quantity of magic from the environment to renew their original reserves. Any excess is placed within this container and kept sealed until absolutely necessary, or unlocked through a Second Origin Release spell. This Second Origin, when initially activated, places an enormous level of stress on the body unless it is awoken in gradual amounts, as the body isn't accustomed to handling so much magical energy in the body at one time. This can be circumvented by mages with control of their magic, however, allowing them to restore the magical power as a reserve that can be accessed whenever required, therefore providing an extremely useful back-up. Second Origin Activation can only be taken place, as said before, by mages who have control over their own magical energy. It generally only works when one is in a magic-rich environment and has nearly exhausted their initial supplies. By absorbing a copious quantity of magic from the surrounding environment passively (which can be noticed through a tingling sensation in the body), the user's internal reserves can be released at the same time. This, in turn, allows for an immense quantity of magic to replace the initial, depleting reserves. Notably, one can allow the Second Origin to passively increase the quantity of magic that is within it, so long as it isn't used during this period of time, otherwise it has to accumulate magic once again. Cobra gained this ability at the time of his trainings, when he was set free. With it, a most interesting part is coming, as when he uses this ability, his control over his magic, both Sound and Dragon Slayer Magic, reaches an enormous level, as he received the opportunities, that he won't have at usual times. Usually, Cobra uses it as his main trump card alongside the Dual Dragon Slayer Mode, becoming as stronger as ever.

Sound Magic
Sound Magic: Cobra has the uncanny Magical ability to hear a person's very soul, allowing him to tell if they are scared, what are they going to do next, and even allow him to hear their thoughts. This ability is so accurate that it was actually confused as mind reading. With it, Cobra was able to foresee all of the attacks performed against him and react accordingly, evading them without effort. His use of this Magic is so great that he was still able to counter each of Natsu's moves even when he tried to hide his thoughts. Though this only seems to work when the person's "voice" he is listening to is thinking, or has memories. The Magic can also act as a doubled edged sword, as high pitched noises, such as Natsu's scream, can affect him greatly. By sacrificing his right eye's sight, he was able to use this Magic offensively, mostly by emitting strong sound waves. After timeskip and harsh trainings, Cobra gains the access to stop his passive side of Sound Magic, which allows him to not hear everything in human's body. Also, he gained other abilities, for example, to remove all sounds from his or other's body, which will make him soundless, as well, as his moves.


 * Sound Wall: Cobra manipulates the sound in his immediate vicinity into a wall of pure pressure, which simultaneously protects him and destroys portions of the surrounding area.
 * Sound Palm: Through touch, Cobra transmits a very powerful sound wave from his palm to the target's body, sending them flying.
 * Silent Touch: With a snap of his fingers, Cobra creates a circular soundproof field to surround himself with. The field prevents any sound coming from within from leaving, as well as blocking all outside sounds from entering. This spell is ultimate, when it comes to some to everyone conversation or receving some information from somebody.
 * Calm Aura: Cobra cancels all noises caused by him. This also applies to noises not caused directly by the user such as objects being thrown on the floor and breaking or explosions caused by weapons. Through this technique, the user can realize otherwise loud tasks without attracting the attention of his enemies. This spell can also be used on other people, which is the ultimate spell to hide someone from the other.

Poison Dragon Slayer Magic
Poison Dragon Slayer Magic (毒の滅竜魔法 Doku no Metsuryū Mahō): By having a Dragon Lacrima implanted into his body, Cobra obtained the ability to use this Magic. It grants him the power to produce poison from his body and to consume the one produced from external sources to heal and strengthen himself, which, as a result, grants him immunity from poison. The poison that he produces from his skin is so corrosive that it is said to be able to decay all that it touches, but can also act after a given amount of time: Cobra stated that its effects are first visible in a progressive weakening of the victim's body, which then results in death.
 * Poison Dragon's Roar (毒龍の咆哮 Dokuryū no Hōkō): Cobra's exclusive Dragon's Roar, incorporating the element of poison. Cobra quickly gathers and releases poison from his mouth in the form of deadly, poisonous stream that, when it makes contact with the target, injects a lethal virus into their body that slowly weakens them and restricts their movement before ultimately killing them.
 * Poison Dragon's Twin Fang (毒竜の双牙 Dokuryū no Sōga): Cobra moves his arms forward in a cross, forming a very large amount of poison in two massive waves shaped like fangs, which he uses to attack his opponents with great blunt force. In the anime, this spell was portrayed differently, with the generated poison being split in many elongated, snake-shaped masses, which all move towards the opponent at once.
 * Poison Dragon's Fang Thrust (毒竜の突牙 Dokuryū no Totsuga): Cobra generates a wave of poison, shaped like a large-fanged snake head, and sends it towards the target, stopping their incoming attacks by having the wave "bite" them.
 * Poison Dragon's Spiral Jaw (毒竜の螺旋顎 Dokuryū no Rasengaku): Cobra jumps in the air and, when he is upside down, gathers poison on his legs and kicks the opponent while rotating. This spell is highly reminiscent of the Dragon's Claw Spells employed by several other Dragon Slayers.
 * Poison Dragon's Scales (毒竜の鱗 Dokuryū no Ringa): Cobra swings his arm, generating a very large number of scale-shaped masses of poison, which are rapidly sent flying at the target in consecutive reprises.
 * Poison Dragon's Fang Slice (毒竜の牙斬 Dokuryū no Gazan): Cobra covers his arms in poison and then launch his opponent high into the air, while making a scratching-like or snake bite-like attack.
 * Poison Dragon's Guard (毒竜の衛兵 Dokuryū no Eihei): Cobra moves his arms forward in a cross, creating a large shield of poison that defends him from the enemy's attacks, and, at the same time, gives him the opportunity to counter without fear of being intercepted.
 * Poison Dragon's Crushing Fang (毒竜の砕牙 Dokuryū no Saiga): Cobra attacks with a poisonous open-hand, striking with his finger-tips from which poison mist trails.
 * Poison Dragon's Grip Strike (毒竜の握撃 Dokuryū no Akugeki): Cobra grabs hold of his target with one hand and releases a burst of poison from it at point-blank range.
 * Poison Dragon's Toxic Fist (毒竜の有毒拳 Dokuryū no Yūdokuken): Cobra engulfs his fist in deadly poison and then punches his opponent, causing, aside from great blunt damage, damage from the venom as well. This spell was strong enougр to break the scales of Rock Dragon.
 * Poison Dragon's Sharp Horn (毒竜の切角 Dokuryū no Sekkaku): Cobra punches his target then releases a burst of poison at point-blank range, which causes poison damage and burns. This spell was strong enough to break the Rock Dragon's scale, and gave the poison inside the dragon's body. After that, it's heavily hinted, that Cobra can make the same with a human's body, implying, that with this spell, Cobra is able to break through the enemy's body.
 * Poison Dragon's Leashes (毒竜の綱 Dokuryū no Tsuna): A spell, which Cobra obtained while he was training for three months. Cobra creates one or two thin, long and tight whipesm which then uses to attack his opponent with strong and distance strucks, pull somebody to him or other. This spell doesn't cause the strong poisoning, but opponent will feel a great pain and burns on his skin, while contacting with the whips.

Dragon Slayer's Secret Art (滅竜奥義 Metsuryū Ōgi): The strongest spells from the Dragon Slayer's arsenal, it is said, that even one spell from this category has the power to defeat a dragon. On the real things, Secret Art of Dragon Slayer can give a great damage to the living beings, even with the opportunity to kill them.
 * Poisonous Mist: Death Trap (毒霧・死罠 Dokumu: Shiwana): One of the trump cards, which Cobra has. Similar to the Roar Spell, Death Trap is a gas-like poison, which revolves around Cobra in big amount. While Cobra can freely control this spell, the mist iself has a high density and doesn't allow to see something in it. With it, the mist is also quite toxic, while the person, which caught up by this spell have only two choices - first is to not breath to save their life, second is to breath, but poison their body. Also, the poison, which mist consists in itself is very dangerous to breathing system of human's body. As a result, the longer person breathes the poisonous mist, the frightener are the consequences.

Dragon Force
Dragon Force (龍力 (ドラゴンフォース) Ryū-ryoku (Doragon Fōsu)) is an advanced form of Dragon Slayer Magic. Dragon Force activates when a Dragon Slayer starts to turn his/her own body into a humanoid dragon, gaining reptile-like scales and traits, such as further elongated and sharp canines for Old-Style Dragon Slayers, and scaly arms, sometimes complete with claws, for New-Style Dragon Slayers. According to Zero, Dragon Force is the most powerful and final state a Dragon Slayer can attain, this granting power comparable to that of a real dragon, and the ability to destroy everything.

Dragon Force greatly increases the damage done by standard Dragon Slayer spells, and grants the user access to more advanced, powerful attacks. It also drastically enhances the user's physical prowess, making them far stronger, more resistent and faster, and boosts their Magic power, prompting it to violently become visible, taking on the shape of a dragon; when used at the fullest, the generated silhouette seems to gain corporeality, likely as a result of the immense amount of Magic power employed. When Natsu Dragneel achieved such state through the use of Jellal Fernandes' Flame of Rebuke spell, his flames also gained the ability to devour offending Magic, even that of Zero's ultimate attack Genesis Zero.

Cobra, as the Second Generation Dragon Slayer, those who have obtained their powers by implanting Dragon Lacrima in their body, can not access Dragon Force mode on his own will. It seems, that Cobra entered this state whenever he makes use of his Dragon Slayer Magic. However, due to this easiness to achieve this form, it is unknown, if his powers become increased at the same level of First Generation Dragon Slayers, as Cobra has no dragon-like aura appearing for him. But, as his powers grew enough alongside his better control over his magic powers, Cobra attained the ability to freely use Dragon Force on his own, just like Third Generation Dragon Slayers. With that upgrade, his powers now gains great increasement, just like other Dragon Slayers of First or Third Generation.

Dual Dragon Slayer Mode
Dual Element Dragon Slayer Magic (二要素の滅竜魔法, Niyōso no Metsuryu Mahō): The Dual Element Dragon Slayer Magic, also known as Dual Element Dragon Mode (モード二要素竜, Mōdo Niyōsoryū) is a Subspecies Magic (亜種魔法, Ashumahō) for First, Second, and Third Generation Dragon Slayers, also known as the ability, they can gain by consuming different element from their main.

Only a few Dragon Slayers have obtained the ability to consume elements other than their own, allowing them to combine both elements inside their bodies and enabling them to utilize the properties of both, as well as increasing their own destructive capabilities. It is also shown to have exceptional penetrative power, and using this ability has been described as similar to using Dragon Force. Even though it's momentary, the user is able to call upon it when they are in a state of anger. However, this ability places a heavy strain on an untrained body, to the point that even a single use is capable of completely draining the user of all their energy. If the user boosts up their power, they are able to use this ability more easily with less strain. However, aside from a few cases, the Dual Element Dragon Mode is extremely difficult to obtain; hence why some have opted to create the Dual Element Dragon Slayer Magic.

Cobra's unique Dual Element Dragon Mode is known as Poisoned Gloom Dragon Mode (モード毒冥竜, Mōdo Dokumeiryū). It is unknown, how Cobra attained this ability, but he spent at least all time of his harsh training after being free for achieving the full control over his Dual Dragon Slayer Mode. Cobra devoured the shadows and as a result, the poison and shadows inside his body fused together, causing him to have the ability to use his Poison Dragon Slayer Magic alonside the shadows. When Cobra enters this mode, his appearance also changes. At first, if Cobra is in Dragon Force state, his Dragon scales' bottoms change their colors from milky and smooth to shadow-like, how it was happened with Future Rogue Cheney (right half of his body) and Gajeel Redfox (his Iron Dragon's Scales), when both of them were using their respective Dual Element Dragon Modes. Interesting, that if Cobra isn't use his Dragon Force, his arms becomes covered in purple-colored poisoned shadows. While the poison and shadows are releasing from Cobra's body, his poison changes its colour from dark-red to dark-blue or dark-purple, hinting to the fusion of poison and shadow, just like his covered arms. Finally, his right eye is opened, but glowing in red, just like Rogue Cheney has his eyes glowing in red, when moving in Shadow Drive-enhanced Shadow Form.
 * Poisoned Gloom Dragon's Shadow Form (毒冥竜の影型, Dokumeiryū no Kagekata): Primary ability of Shadow Dragon Slayers, which Cobra obtain alongside his shadows. He can takes the shadow form, which makes Cobra intangible. With this Spell, Cobra is also able to move swiftly, dodging efficiently and making surprise attacks for his enemies. He becomes more dangerous with this spell, as he remains his poison powers, so he can make even more mortal wounds.
 * Poisoned Gloom Dragon's Roar (毒冥竜の咆哮, Dokumeiryū no Hōkō): Shadow-enhanced version of Roar Spell. Cobra generates both poison and shadow in his mouth, and then, he releases a large destructive blast of poisoned shadows, which, when makes a contact with the target, injects the lethal virus of Poison Dragon, which slowly kills its victim alongside the slicing damage of shadows.
 * Poisoned Gloom Dragon's Slash Blow (毒冥竜の斬打, Dokumeiryū no Zanda): Shadow-enhanced version of Fist Spell. Cobra engulfs his fist in poison and shadows, and then, deliver a strong punch, causing the great blunt damage alongside the damage from poison and slicing damage from shadows.
 * Poisoned Gloom Dragon's Kick (毒冥竜の足蹴, Dokumeiryū no Ashige): Shadow-enhanced version of Spiral Jaw Spell. Cobra engulfs his leg or legs in poisoned shadows, and then, devlivers a kick to his opponent. Along with great blunt damage, Cobra also gives poison damage with slicing damage from shadows. Also, Cobra can make this move while rotating, which can gives him addition to his power attack.
 * Poisoned Gloom Dragon's Destroying Fang (毒冥竜の破棄牙, Dokumeiryū no Hakiga): Shadow-enhanced version of Crushing Fang Spell. Cobra gathers the poisoned shadows on his fingertips, and then, delivers an attack to his opponent. Alongside the poison damage, Cobra also deliver a great slicing damage from shadows.
 * Poisoned Gloom Dragon's Scales (毒冥竜の鱗, Dokumeiryū no Ringa): Shadow-enhanced version of Scales Spell. Cobra swings his arm, generating a very large number of scale-shaped masses of poisoned shadows, which are rapidly sent flying at the target in consecutive reprises. This spell has great area damage, with slicing power from shadows and poison damage.
 * Poisoned Gloom Dragon's Wing Slash (毒冥竜の翼斬, Dokumeiryū no Yokuzan): Shadow-enhanced version of Twin Fang Spell. Cobra moves his arms forward in a cross, forming a very large amount of poison and shadows in two massive waves shaped like fangs, which he uses to attack his opponents with great blunt force. This spell has great slicing power from shadows.
 * Poisoned Gloom Dragon's Falcon Flash (毒冥竜の鷹閃, Dokumeiryū no Takasen): A spell, which Cobra takes from Shadow Dragon's arsenal. Cobra turns his body in poisoned shadows, and then wraps himself around the target, assaulting them with a torrent of poisoned shadows from his hands, becoming tangible once more.

Dragon Slayer's Secret Arts: Revision (滅竜奥義・改, Metsu Ryū Ōgi: Kai): A revised version of strongest spells from Cobra's arsenal, with adding Shadows to his Secret Arts, resulting in enhancement with shadows power and increasing of overall strength of his spells. it is said, that even one spell from this category has the power to defeat a dragon.
 * Poisonous Mist: Dark Spear (毒霧・暗黒の槍, Dokumu: Ankoku no Yari): Spell, with which Cobra makes his strongest weapon. He creates from poisoned shadows a double-blade spear. Alongside this spear, Cobra's arms often also become covered in this poisoned shadows. With this spear, Cobra's power becomes increased dramatically. This spear is unique among Cobra's other spell, as while this spear gives great poison damage with slicing damage from shadows, when contacting with its target, the spear itself leaves a deep wounds, which have a trait to not heal as a usual wounds. As a result, Cobra's opponent takes enormous damage with poor wound healing, and for some time afterwards, gains a decreasement of regenerative abilities.
 * Poisonous Mist: Darkness Form (毒霧・闇の形態, Dokumu: Yami no Keitai): By the words of Cobra, this Secret Art is his most powerful spell, even powerful than Dark Spear. He gathers the poisoned shadows around himself, just like in Death Trap Spell. After this poisoned shadows dissappeare, Cobra gains a monster-like form, which can frighten Cobra's enemy just by its look. Alongside this fear appearance, Cobra gains a big increasement of his powers, no affection to pain or wounds. Also, this cover has a very high level of poison and shadow atributes. While in this form, Cobra has the ability to easily create poison, much faster make his body intangible, and while contacting with his opponent, he passively delivers poison damage as enemy feels it like it's burning, alonside the small cut wounds. But, as this spell has great power, it's has great weakness. While continiously use this spell, Cobra's control over his emotions and personality slowly decreases, as he fights more with his instincts ans in savage way, while he can easily think about killing his enemy, not defeating them. When this spell is over, Cobra has a great weakness within his body, great exhaustion and need to rest for a few days. While using this spell, Cobra usually use his Second Origin Activation and his Dragon Force in attempt to better control the spell.

Trivia

 * This character was approved by User:Perchan.
 * The reason Cobra has controlled Dragon Force, as in the manga at time, when he was fighting the Rock Dragon, he used his Dragon Slayer Magic without entering the Dragon Force state. The same goes for Laxus, when he fought Hades (pre-timeskip), Jura and Tempesta (post-timeskip).
