I do not own Evangelion or Avatar: the last airbender
Water. Earth. Fire. Air. Frost. Lightning.
Once upon a time there was a planet called the Enow, which is located in the Andromeda galaxy. But only the Avatar is able to use the power of all six elements and all combinations of elements. In the world there are different people, but most of the six countries that use the six elements and these elements and the earth called the Fire nation, Earth kingdom, Water tribes, Air nomad, Lightning realm and Frost republic, and that country are very strong and specific.
Now in the planet Earth, the Benders is not excite, but that all change when is born the First Avatar in the galaxy Milky Way. That's why in Enow Aang and friends begin the new adventure.
