Dark Aura

Dark Aura is the dark Counterpart of Paul Gekko. He is part of the Creation of Heaven Tail.

Appearence
Like most Yamata no Orochi, the Dark Aura is large in size; the upper part of its head, its back, upper portion of its tail, arms, and talons. Its underbelly and jaw, which is filled with very sharp teeth, are white and smooth, with its abdominals in particular being quite muscular. Unlike most Dragons, the Dark Aura, rather than having claws, has extended digits and a smooth, dark patagium, making its anatomy and method of flight more akin to a bat's than an actual Dragon's; additionally, there are spikes running down from the Dark Dragon's spine and onto its tail, which in itself ends in a rippled, almost torn fashion.

Personality
Dark Aura was an impartial entity, completely devoid of feelings and ideals as it stayed neutral and almost ambivalent to the constant wars that were waged around it by mankind.

Background
A millennia ago, God made a pact with Sai Gekko along with Ribbons Gekko to create the Guild for every one to share the Peace and prosperity. As they finally finish the guild building, all four take a photo with the building in background as a sign that Heaven Tail is Born, and, in gratitude, after Sai and Ribbons' Death, the members of Heaven Tail make a grave inside the Temple of Heaven Tail during the era of endless wars at the dawn of the human race, and Dark Aura was worshiped as the host of a god. Every millennium, Dark Aura will come to the Kamigakure would choose a Shinobi King or a Shinobi Queen to rule the Land of Heaven Tail. During this era, conflicts perpetually arose between the various nations as each crusaded for more rights and land. In order to wage these wars, each individual shinobi clan rented its military might to the highest bidder. Due to the unrelenting violence, the average life-span for a shinobi as well as civilians were a mere 30 years, though the single biggest reason for the continuing fall in life expectancy was the slaughter of countless conscripted Children's Parents. At some Point, Dark Aura chose Kusanagi Gekko and Laura Gekko, the Members of the Gekko Family as King and Queen of Shinobi to end the wars plaguing the lands.
