Quirk - Ruiner Stygian Zigante & Dragon Element

Quirk Type - Transformation/Emitter

Y/n's quirk grants him the abilities of a two ancient wyvern's know as Ruiner Nergigante & Stygian Zinogre, the quirk also allows him to produce energy called Dragon Element in the form of crimson red lightning and black mist, which he can produce from his body and mouth, but Y/n's quirk in mainly a transformation type. But it seems that the monster that he turns into is a combination of the two wyvern.

Y/n gained some mental and physical things of the two wyverns, where he cannot turn off such as likes, dislikes, personality, going into heat, having sharper canine teeth, weaknesses that have not been found yet. His quirks abilities are separated, One, he can grow out wyvern parts from the inside such as his claws, tail, and spikes, he can also grow the bones along with it.

Two, he is able to transform his insides into wyvern parts, like his eyes, organs and actual wyvern teeth etc. But if he transforms his brain he will have part of a wyvern personality, having almost no speech, being vicious, violent and simply act more like a wyvern than a human being.

Three, if he transforms fully, he would go into a full wyvern form, having a full personality and body of one while being fully in control, but can turn into a wyvern at will and can change back anytime he wants, but once he changes back, he must wait a few minutes for his abilities to come back, but the abilities he can't turn off remain. But Y/n is able to use his wyvern features to his advantages in fights.

Weaknesses - 

He also need to control his aggression and needs to make sure he doesn't hurt and fatally injures his opponent's.  

Limited Range. The quirk nullification only works within a certain radius, and individuals outside of that range are unaffected.

Energy Exhaustion.  Prolonged use of Dragon Element, especially in its more powerful forms, drains the user's stamina rapidly. Overuse can lead to severe physical exhaustion or even temporary loss of their own abilities.

Nullification Shielding. Certain quirks or high-level opponents may develop resistance or countermeasures to reduce the effects of Dragon Element, especially if they have trained extensively against quirk-disabling techniques.

Abilities -

- Dragon Element. This is a powerful energy that Y/n is able to produce in his human form and Wyvern Form. This increase his strength, speed and rage, he can even blasted it out of his mouth in powerful streams of energy causing massive explosions of, it comes in the form of black mist and red lightning and destabilizes the quirks of anyone within a certain range, making it impossible for others to use their abilities effectively. The strength of the nullification depends on the proximity to the user, the closer the target is, the more their quirk is suppressed.

Dragon Element Manifestation. Beyond quirk nullification, Y/n can weaponize the raw dragon element, forming energy blasts, shockwaves, or even creating a protective barrier of energy around him and his allies. This energy can be shaped into claws, wings, or other destructive forms, mimicking the ferocity of dragon-like creatures.

- Scales/Spikes. Y/n's wyvern scales and spikes are jagged and knife like, these types of scales allow Y/n to move in ways a normal animals couldn't, if someone were to attack Y/n physically they would get cut very easily being able to slice through flesh like butter. The scales allow Y/n to be very flexible since the scales flow over each other enabling him to move very quickly. But Y/n's spikes and claws have a unique feature being coated in a blood thinning agent, which when it comes into contact with blood makes in thinner and more liquid, it cause heavy bleeding and blood loss to anyone who is even scratched a little by the claws of spikes

- Enhanced Strength. While in his dragon from Y/n is extremely strong able to send a person flying with ease, and possibly strong enough to flips cars, and due to him having a dense skeleton, this caused his wyvern form have very dense and flexible muscles.

- Intelligence. With the powers that come with the his quirk, it also lets him have extremely high intelligence. This allows Y/n to analyze his opponents for any weaknesses for him to take advantage of them and Y/n even uses minimal movement and power against opponents that are not worth the time.

- Stamina and Endurance. Y/n's stamina and endurance seem to be incredibly high, even for human standards. This allows Y/n to last longer in fights that require him to stay in his human form.

- Immense Durability. In his Wyvern form, Y/n has a lot of durability to withstand strong, blunt attacks from other. This is due to his skeletal system having a denser build than his human form.

- Speed/Agility. Even though his wyvern form looks bulky he is extremely fast being able to run up to 60 mph and is able to jump extremely high in the air being able to dodge attacks at lightning speed.

Aggressive Abilities -

- Claws. Y/n is able to grow claws from in finger nails and they are extremely durable and sharp, able to cut through the toughest materials.

- Teeth. Y/n is able to grow razor sharp teeth in his mouth that are serrated that can tear through metal, and even flesh.

- Scales/Spikes. Y/n is able to cover any part of his body in wyvern scales, it further increase his durability and defense, to allow him to take massive amounts of damage, but over time the scales can be broken. This is because Y/n's wyvern form scales are much harder that when he use's them in his human form, Y/n able to withstand high intensity heat and fire and extreme cold and frost in his wyvern form and human form.

- Dragon Element. Y/n is capable of using his dragon element for the same uses just like in his wyvern form.
