Vaatu

Vaatu was a spiritual being who was created in ancient times by the Celestial Force god known as the Son. He was the manifestation of darkness and chaos across the planet Reylea and its Sixteen Realms, in opposition to his twin counterpart, Raava, who was the spirit of light and peace. He was the first spirit to ever cross over from the Spirit World into the material realm of Reylea, creating the Northern and Southern spirit portals that enabled other spirits to do the same. However, Raava intervened in his quest to break through the divide of all sixteen realms, seeking to restrain him so that he could not bring all of Reylea under his dominion. Much of Vaatu's existence was spent combating Raava in an effort to consume Reylea and its realms in darkness, though neither were able to ever fully destroy the other.
During Reylea's first age, Vaatu and Raava were forced into a temporary alliance with the emergence of the Oni, a race of immensely powerful beings who served the Darkness itself, a paracausal entity which even Vaatu feared. With Reylea and all Sixteen Realms facing the threat of imminent destruction, Vaatu and his eternal foe fought together ― alongside many others across the realms, including the Ones ― in a war of cosmic proportions to defeat the Oni. Vaatu himself participated in a great battle against the leader of the Oni, assisting in the demon's imprisonment in the Source Wall, a cosmic barrier existing beyond the Ethereal Divide.
Following the Oni War, Vaatu and Raava inevitably resumed their conflict for control over Reylea's fate, and during the Harmonic Convergence in 9,829 BG his victory seemed all but assured. However, he was defeated by the human Wan after he merged with Raava to become the first Avatar, and was subsequently locked inside the Tree of Time, with his only hope for escape being to wait ten thousand years for the next Harmonic Convergence to take place.
==Personality and traits==
Vaatu was an ancient and powerful spirit whose appearance resembles a large "kite" with long wispy tendrils, was colored a dark red and orange, and exuded an aura of darkness around him.
A cruel and manipulative being, Vaatu was consumed by his single-minded objective to destroy Raava and bring about ten thousand years of darkness upon the arrival of Harmonic Convergence. His apparent distaste for Raava is intrinsic to his very nature as her spiritual counterpart, though it is further exacerbated when Raava managed to keep him in check and later, after having merged with Wan and sealed him in the Tree of Time, fueling his desire for revenge. He relentlessly seeks to spread chaos and destruction, as they increasingly give him strength. 
Despite being a personification of chaos, Vaatu ironically exudes a calm persona, never losing focus of his goal or even panicking if faced with certain defeat. He is also very patient, willing to wait thousands of years while trapped in the Tree of Time for someone to free him, certain that the dark and selfish desire of humankind would do so. He is confident in his abilities, though his pride waxes into pure arrogance when he deals with humans, a race which he disdains, believing that no human could ever challenge him as he was far older and more powerful than they were. Even after being defeated by Avatar Wan he refused to acknowledge Wan's reincarnations, and would only refer to Raava whenever in the presence of an Avatar. Vaatu was also manipulative and cunning, as he tricked Wan into freeing himself from Raava's grasp by using the human's love of spirits.
The only beings that Vaatu acknowledged as above him were the Ones, a family of powerful Force wielding Celestials responsible for his and Raava's creation. However, despite recognizing the Father and Morai as greater than him, Vaatu only held genuine respect for the Son, who was his creator. Vaatu's hatred of Raava was also in complete contrast to the Son, who still loved his sister despite being her opposite.
==Powers and abilities==
As a spiritual being created by the Son, Vaatu was a powerful entity who held a strong connection to the dark side of the Force, albeit in a far different manner than most.
As the spirit of chaos and darkness, Vaatu has the ability to magnify the negative emotions inside other spirits, swaying them to give in to the darker sides of their natures. In turn, he feeds on chaos and anarchy, increasing in both size and power as more destruction ensues. Because he does not possess a definite physical form as a spirit, he is able to fly and remain unharmed whenever struck by an attack, while also being able to enter physical combat and produce kinetic force. He also has the ability to shoot powerful blasts of purple energy beams through use of the dark side of the Force. Like all spirits, Vaatu could inhabit the body of most humanoids and enforce his will through them, though he rarely did so due to his disdain for any being he considered lesser than himself.
Like his counterpart, Raava, Vaatu is effectively immortal, having lived for tens of thousands of years. If he is overcome by Raava, he can gradually reform himself from the vestigial darkness within her. Despite being separated from each other for thousands of years, Vaatu still shared a connection with Raava, and was able to sense her presence whenever the Avatar crossed over into the Spirit World.
