Dust Devil

Note: This does not represent canon material in anyway. This page is just for me to record down some ideas I had.

A Dust Devil is the catergorisation of a very powerful and dangerous type of creature of Grimm, which has the very specific trait to influence Dust within their immediate vicinity to spontaneously explode.

With this power and given how much purified Dust exists within the human cities of Remnant (imagine anywhere you would normally put fuel and gas and substitute those with Dust), Dust Devils are thus regarded as humanity's greatest bane and their entrance into any populated area will undoubtedly lead to cataclysmic destruction. Their ability also leads to Hunters trying to stop them being placed under a huge disadvantage, as their Dust-powered weapons will likely explode in their hands before they can even get remotely close.

The Truth
However, Dust Devils are absolutely NOT creatures of Grimm. It is theoretically impossible for the creatures of Grimm to be able to do such a thing, as the strengths they have can only originate from biological or chemical means and even if such a creature can obtain such a power, Dust also exists in nature itself and hence from an evolution standpoint, such creatures should gone extinct a long time ago.

The only way that a Dust Devil can remotely initiate the explosion of Dust is through what is recognized as having a unique relationship with it: Aura.

A Dust Devil is hence, little more than unfortunate people who possess the secretly-named 'Dust Devil' Semblance or in less technical terms, are called 'allergic to Dust'. It is unknown to scientists how is it that a single Semblance can appear near-exactly the same throughout all of its users, for the uncontrollable Dust Devil Semblance induces its possessor to be physiologically attracted to Dust when it is nearby, near akin to a sudden addiction to its drug-like presence. Furthermore, their image as a creature of Grimm is further reinforced by the fact that when their Semblance activates, the person turns brilliant white as minute and harmless explosions of tiny Dust particles in the air around them occur. Even though this eventually clears, by the time it does, a city is likely turned to ruins.

Why lie?
Because what ultimately distinguishes Hunters from the normal people is not their weapon or their training, but their ability to use Aura. As a result, the popularity of the superhuman Hunters around the world hinges upon the acceptance of Aura. If people were to find out that Aura has the ability to cause major destruction through their basic way of life, even if it arises from a single unique type of Aura, the general image of Aura and in turn Hunters will be marred. That is why the Hunter organizations strive to ensure the illusion that Aura is exclusively beneficial to humans and is akin to a blessing bestowed by some unknown being on 'special' individuals so that they can lead humanity out of the hopeless darkness.

As a result, the Dust Devil possessors had to taken out of the picture and segregated from the rest of the crowd. And what better way to do that than to claim that they are creatures of Grimm, scientifically proven to have no Aura at all. This 'transformation' from man into monster has taken over a century, with the organizations making use of the media, the government and most importantly, the Hunter Academies to virtually wipe out the memory of the 'Dust Devil' Semblance and replace it with the Dust Devil Creature, the scourge of humanity. Furthermore, they also have a special taskforce, armed with traditional non-Dust weapons, to look out for budding Dust Devils, who are likely children, and to kill them off before their power comes into full swing.

The issue is highly debatable, for both sides of the argument give strong points. Proponents of this censorship and re-education assert that the power of Dust Devils were in complete conflict with the very basic necessities, Dust, that everyone else needs and hence even if the truth comes out, Dust Devils will be even more ostracized and shunned by the world. Therefore, it is for their own 'protection and for the greater good' that they cease to exist in today's Remnant. Opposers will state that what they are doing is little more than cold-blooded self-serving genocide and some have even claimed that if given time, Dust Devils can control their Semblance just like any other, allowing them to assimilate into society. In fact, society should be welcoming enough to alter itself to let them in. They are just not being given the chance. Furthermore, fully-grown Dust Devils missed by the taskforce will become branded as monsters and that sort of treatment will only serve to catalyze their hatred of the rest of mankind, leading them to fully metamorphize into "the monsters that we want them to be".
