Nidhogg

Nidhogg (ニーズヘッグ) was a black dragon who was a ruler hailing from the 12th Realm who was sealed in one of the old abandoned bases of the Cult of Diablos near the academy town of Laugus until it was awakened by Eta by mistake, whereupon this Dragon was slain by Shadow.

Appearance
Nidhogg appearance, similar to the dragons of the world where Cid Kagenō lives, before magic came to him, but with a more demonic appearance than normal, His size is double, or more, than that of the Mist Dragon. Both his skin and his scales that cover his entire body are harder even than Mithril itself, making him impossible to hurt, even with the artifacts that are part of the heroines. He is a quadruped being, with a huge tail, the end of which is in the shape of a huge semi-drident with 2 very hard points. Like all Dragons, it carries with it 2 huge wings, black and red in color, (where one of these, its left wing, is damaged by the wounds it suffered when it became a prey to the Cult of Diablos), the edges Said wings are semi-pointed and have a pair of very large chusos, in the upper unions of their wings, which is why it usually resembles something evil and can use said large chusos, either to fight while flying or when it is in flight. land.

It has a very long neck, where there is a row of eyes, going down its entire neck, and a few more of these eyes are found on its two frontal blades, one on each side, it has a huge semi-triangular head with two pairs of huge red horns, which measure almost the same as its mouth, which are bent forward, and it has 3 pairs of eyes that range from red to yellow, and its mouth is covered with very sharp fangs that never deteriorate, being able to swallow and eat anything. several people in one bite.

His entire body in general is mostly black, while some parts of it, such as the horns on his head, and his dragon wings among other things, are red. He has very strong and sharp claws, capable of tearing apart and cutting everything that comes their way, from a strong knight in armor, to huge buildings, without any problem. Due to its demonic features, it is considered that the Black Dragon may have part of the blood of demons throughout its body, which would explain its demonic features.

Personality
Unlike other Dragons from different realms, Nidhogg stands apart with its feral nature, lacking intelligence, and driven solely by instinct, much like any wild animal or creature.

Nidhogg possesses a sinister and malevolent essence due to its demonic biology. Merely being in its presence evokes a profound sense of chills and fear, even in individuals with strong spirits. When Zeta and Eta found themselves face to face with the sealed and slumbering Nidhogg, they couldn't help but tremble, overwhelmed by the imminent danger and the dreadful aura it emanated. Their fear escalated further upon its awakening. However, Shadow, uniquely unaffected by the Nidhogg's supernatural intimidation, remained steadfast in the face of its sinister presence.

Powers & Abilities
Nidhogg was a magical being of great power, which was said to be able to sweep an entire country, in less than a day. Said Dragon was so powerful that not even 2 of the Seven Shadows of Shadow Garden, Zeta and Eta, in full capacity and growth, both in magical power, and in the rest, could defeat it. It was not until Shadow happened to pass by there, when feel the awakened magical power of the Black Dragon, and at the end, Shadow killed him with a "I Am Atomic".

Dragonic Prowess
Like all Dragon, the Nidhogg Dragon, possesses a supernatural strength, very tremendous, being double, or possibly more, than that of the Mist Dragon, enough to destroy from huge buildings, even possibly a mountain, by brute force. Due to having a partly demonic biology, said dragon had the characteristics partly of Demons, such as perceiving magic around, plus a sinister evil nature, among other things, which he wanted to face, to the point of be almost impossible.

Semi-Demon Biology
Despite being a dragon and having the characteristics of one, both in magic and in the rest, according to the studies and analysis of Lord Laugus, plus the partly visible that it was, said dragon had some genes of magical beasts and Demons. in his body, which explained why he possessed or perceived a dangerous and sinister nature from him, when one looked at him and felt it.

Dragon Roar
Nidhogg, like all dragons, possesses the ability to unleash a powerful dragon roar that can be heard over long distances. This roar generates a strong sonic wave capable of damaging solid structures, instilling fear and panic even in the strongest warriors of other realms. Only the Seven Shadows of Shadow Garden have shown some resistance to the intimidating presence of this dragon, with the Shadow Master being completely unaffected by its sinister and supernatural nature.

When Eta mistakenly provoked the dragon, it responded by unleashing a deafening roar at the two Shadows of Shadow Garden. Both Zeta and Eta struggled to maintain their sanity while attempting to harm the dragon, but their efforts proved futile. However, when the dragon faced Shadow, it received the same sinister gaze and roar in return. Surprisingly, Shadow remained unfazed and even became excited to confront the dragon once again. He managed to injure and ultimately kill the dragon with relative ease.

Magic Flight
As a powerful dragon, Nidhogg possessed the ability to fly at supersonic speeds, surpassing even the dragons of other realms, as indicated by Lord Laugus' studies. However, it was only when Laugus and his people, former members of the Cult Of Diablos, utilized highly potent magical artifacts that they were able to damage one of the Black Dragon's wings. This temporary impairment enabled them to capture Nidhogg and subject it to captivity and experimentation.

Physical Invulnerability Conventional
Similar to other magical dragons from different realms, Nidhogg possessed invulnerability against conventional weapons crafted by humans or other intelligent races. This meant that the dragon remained impervious to any form of damage caused by firearms, fire, or hand-to-hand combat. It is even speculated that Nidhogg, as a formidable ruler, could withstand the most powerful firearms on Earth without sustaining any injuries, without the need for resorting to nuclear weapons.

Near Invulnerability To Magical Weapons

Nidhogg's invulnerability extended to magical weapons as well, including those of cutting nature. Not even Mitrilh, the toughest metal in the Other World, with exceptional magical conductivity, could leave a scratch on the dragon's skin. Even the Slime Weapons created by the members of Shadow Garden, which boasted 99% magical conductivity, were incapable of inflicting harm upon the Black Dragon. The only possibility of damaging Nidhogg with such weapons would require the user of the Slime Weapons to possess exceptional control and an immense amount of magical power.

When the Dragon Nidhogg was mistakenly released by Eta, when she and Zeta found the Sanctuary, where Lagus had the Dragon imprisoned and sealed, at the beginning of the confrontation, neither Zeta nor Eta, 2 of the Seven shadows of Shadow garden, they were able to even scratch the Black Dragon, not even with their slime weapons, and their magic, in full development of magical power, at a strong level, being in certain comparison, at the same state as that of the 3 Heroines. This taking into account that Zeta is one of the 7 strongest Shadows in the group (she being number 3 in it).

Only Cid Kagenou, while in his Shadow alias, managed to deal heavy damage to the Black Dragon, due to Cid's tremendous magical power, plus control over it, saving Eta and Zeta, in the process. then for the end, eradicate the Dragon along with the facilities where they had sealed it, with an "I Am Atomic", leaving no trace and evidence of the black Dragon and the facilities in the process.

Nearly Immortal (Average)
Similar to other dragons in the Other World, Nidhogg possessed a form of ancient magical immortality that prevented it from succumbing to old age, poison, hunger, thirst, and other natural causes. According to Lord Laugus' studies and analysis, Nidhogg was impervious to the ravages of time. However, unlike other dragons, Nidhogg lacked the ability to rapidly heal from powerful magical wounds inflicted by beings stronger than itself. This was attributed to its wild nature and the absence of concentrated magical energy for focused healing.

While Nidhogg was an immensely powerful creature, surpassing numerous dangerous beings in terms of destructive capabilities, it was not invincible. This became evident when Nidhogg, recently awakened and magically restored, confronted Shadow. In a natural course of events, Shadow defeated Nidhogg with an "I Am Atomic" attack, resulting in Nidhogg's demise along with the destruction of another sanctuary where it had been imprisoned. The ground showed no trace of the dragon's existence, as if it had never been there.

Magic
Despite ruling over a world that was not as vast as others, Nidhogg possessed significant magical power according to Lord Laugus' studies. It exhibited swift magic recovery akin to other rulers, enabling the dragon to employ its magic continuously without succumbing to exhaustion. This categorization made Nidhogg a potential threat not only to several countries but potentially to an entire continent or even the world within a matter of weeks.

Breath Magic of Black Dragon
Similar to all dragons, Nidhogg possesses the ability to unleash a powerful burst of magical Dragon breath. However, Nidhogg's Dragon breath surpasses that of the magical dragons in the world of Cid Kagenō in terms of power and speed. Its breath can extend to the horizon, causing massive explosions capable of destroying entire cities or even vast islands within moments. In extreme cases, Nidhogg's breath could obliterate an entire country in a matter of hours, relentlessly unleashing consecutive attacks without apparent exhaustion. Its destructive force reduces life and matter to dust, leaving virtually no trace behind.

During its recent awakening, Nidhogg encountered Zeta and Eta, two of the Seven Shadows of Shadow Garden. While the dragon was healing its old wounds, primarily on one of its wings, it attempted to unleash its powerful Dragon breath to eliminate Zeta and Eta in a single attack. However, Shadow intervened, interrupting the dragon and inflicting damage, preventing it from fully charging its devastating assault.

Weaknesses:
Despite its tremendous powers, the Black Dragon also had its vulnerabilities, similar to the Demon King Diabolos. Like Diabolos, the Dragon could be subdued, sealed, and rendered immobile through the use of powerful sealing artifacts, such as the magical chains employed against the Arm of Diabolos. Another weakness of the dragon was its susceptibility to magical attacks and artifacts that possessed a significantly higher level of magical power and conductivity compared to its own. These attacks could prove fatal to the dragon, breaching its defenses and resulting in its demise, such as the "I Am Atomic" technique employed by Shadow.
