<p>That would mean that if the Dark Avatar spirit does reincarnate, than a child in the Earth Kingdom has become the new Dark Avatar. </p>

Perhaps but I never heard them confirm that they would "Be together through all their next lives".

<p>It's kind of a given and doesn't have to be said out just like what happened with Wan and Raava. </p><p>Also, why would he be born as a child in the Earth Kingdom. Unalaq could only bend water. </p>

<p>@Avatarlonathan Exactly... nor did they claim to be one spirit haha. </p>

<p>I doubt that there would be a next Dark Avatar. Considering what Korra looked like when she fused with Raava, I think the form Unalaq took when Korra defeated him would be the "Dark Avatar Spirit." Chances are it wouldn't be too different between the Avatar and Dark Avatar in that if the spirit is bested, the reincarnation cycle ends. </p>

<p>However, Unalaq ripped Raava right out of Korra and proceeded to pummel her until she disintegrated thus destroying the Avatar cycle. Korra on the other hand used the waterbending purification thing on Unalaq/Vaatu. The two didn't necessarily seperate nor do we really know what happened to them both. </p>

<p>True, we don't know what happened to them, but the Avatar does not need to be separated from Raava to put the Avatar spirit in danger. The most prominent example is in the Book 2 finale of the original series. I don't think Aang was disconnected from Raava/the Avatar spirit like Korra was when he was shot with Azula's lightning, and that nearly ended the Avatar cycle. </p>

<p>From what I gathered, Vaatu is inside Raava, which is inside Korra. However, we don't know if the Avatar will reincarnate (but it probably will at the end of Korra's life time). </p>

<p>them the question is, will the next avatar be the raava-avatar or the vaatu-avatar? </p>

<p>
I'm betting it'll still be Raava-Avatar. I mean, both Unalaq and Vaatu got beaten pretty hard, and they won't be coming back anytime soon. </p>
