(got one i've been thinking of ever since i say this thread)
Dragon Vein: The ability to discharge a napalm-like substance, which is generated in a special organ and sent through blood vessels when used, from ones orifices, including the mouth and open wounds. This substance, when in the presense of oxygen, which causes it to instantly ignite, burns at temperatures in excess of 10,000 ┬░C and behaves similarly to a less viscous version of glue. The user is resistant to heat to the point that they are completely unaffected by the presense of the substance in their veins, a vastly more effecient digestive system, signifigantly increased Regenerationn and modifications to their eyes that allow them to see despite the immense heat/haze emitted by the substance.
Limitations: Other than the fact that the vast majority of clothing will be vaporized the instant the user uses their quirk and that it can only be used in the direction of openings on the users body, the substance tends to cause a large amount of collateral damage. Even though the users digestive system is far more efficient than that of a normal human's, they still require hundreds of times the caloric intake of a normal human in order to sustain the special organ, otherwise it will begin to decay and eventually die and be absorbed by the body. In order for the organ to function correctly, it requires the constant presense of blood and adrenaline, as it consumes these to create the substance, which can cause it's own problems, such as adrenaline poisoning or the users body becoming exhausted noticably faster than it normally would. In additon to all of the above, several attakcs that can be preformed by the user are effectively suicide attacks, and, even if the user survives, results in the destruction of the special organ, which is not believed to be able to be regerated by the user.
Equipment: While no special equipment is needed for the user other than normal armor, their team members will most likely need to be equipped with heat-resistant suits (unless they don't plan on operating close to the user), which, due to the sheer heat of the substance, will likely be quite bulky and difficult to use.
Special Moves:
- Dragon's Breath: The user expels large amounts of the substance through their mouth
- Dragon Lance: The user induces Vasodilation, increasing blood flow which allows more blood to be converted to the substance at a higher rate, which, when expelled, comes out far more compressed than it would be normally, and will fly far further
- Dragon Cloak: When the user has been damaged on various parts of their body, although they need to have been deep enough to bleed, the user can expel the substance in all directions nigh-simultainiously
- Lesser Dragon Burst: The user makes it so that the substance cannot be expelled from their body and simply be continually run through the special organ, making it burn hotter and hotter, until the heat causes a chain reaction in which the organ forcibly converts upwards of 90% of the blood in the users body into a super-heated (~10x to 100X hotter) version of the substance. The sheer heat of the substance overpowers the users heat resistance and, when expelled, causes extreme damage to the user's entire body and temporarilly disables to organ due to lack of blood to convert.
- Major Dragon Burst: A variation of the LGB, with the only difference being that a variety of chemicals are used to allow the user to run the substance through the special organ for far longer than before. After around 12 hours of this process, the sheer heat of the substance causes the atoms of the users body, and the nearby environment, to undergo nuclear fusion, causing a nuclear explosion that has the explosive power of at least 700 megatons of TNT. This techinque has an effectively 100% chance of killing the user due to how it works, although sufficient healing, through convential means or other quirks, allows the user to return to full health, only without the special organ, permenantly disabling their quirk.
