Vaatu turned the spirits' anger against them, turning them into dark spirits. Vaatu met with Raava and Wan once more at another conflict between spirits and humans. Vaatu battled Wan and Raava for supremacy right before Harmonic Convergence. He taunted Raava over growing weaker due to his proliferation of chaos and threatened to destroy her forever during the upcoming Harmonic Convergence, which would take place a year later. However, Wan and Raava's intervention prevented him from laying waste to the village. His presence transformed the peaceful spirits living there into rageful entities.

ĭuring his travels around the world, he discovered a hidden village of men atop an airbending lion turtle. Free to roam the world, he spread chaos wherever he went, growing stronger and weakening the light in the process. However, when Wan arrived during their battle, Vaatu seized his opportunity and tricked Wan into separating him from Raava.

In the ten thousand years since the Harmonic Convergence immediately before Wan's time, Vaatu had been in conflict with Raava and was restrained by his light counterpart. Vaatu, losing the battle to Raava, tricked Wan into helping him. As a result, Vaatu receded into Raava and the Avatar, where he will continue to grow stronger and eventually break free. Their form, however, was purified by Avatar Korra during their battle. During the next Harmonic Convergence in 171 AG, Vaatu permanently merged his essence with Unalaq's, becoming the Dark Avatar Spirit.

ĭuring the Harmonic Convergence in 9,829 BG, Vaatu was defeated by a merger of Wan with Raava, and subsequently locked inside the Tree of Time for ten thousand years. The reverse would happen to Raava if she were victorious over Vaatu. Even if Vaatu were to destroy Raava, what little light there was in him would magnify until a reborn Raava burst forth, beginning the cycle again. Vaatu and Raava, the spirit of peace and light, spent much of their existence combating each other, at least since the Harmonic Convergence of 19,829 BG, with neither able to fully vanquish the other. His essence swayed the spirits to the dark side, transforming them into dark spirits. He was the first spirit to cross over into the mortal world, breaking down the barrier that separated it from the plane of spirits and creating the Northern and Southern spirit portals in the process, enabling other spirits to do the same. He is one of the oldest known spirits, having existed over ten thousand lifetimes before the appearance of the first humans.
