Vaatu (Earth-3813)

"I lived ten thousand lifetimes before the first of your kind crawled out of the mud. It was I who broke through the divide that separated the plane of Spirits from the material world. To hate me is to give me breath. To fight me is to give me strength. Now prepare to face oblivion!"

- - Vaatu to Wan

Vaatu, also known as the Ten-Tails, was the spirit of chaos and darkness who became, for a brief moment, the Dark Avatar spirit during the Harmonic Convergence of 1151 BG. One of the oldest spirits known to man, Vaatu existed for over ten thousand lifetimes before the first humans appeared on Earth. He was also the first spirit to cross over the mortal world from the barriers that separated it from the Spirit World, leading to the creation of the spirit portals, which allowed other spirits to do the same in the form of summons. In order to end the darkness on the world created by Vaatu, the fabled Sage of the Six Paths split the chi of the creature into nine tailed beasts to ever stop its return.
