I remember seeing this thread on a now dead Avatar forum.

Black hair, red eyes. Brown hair, green eyes. They are distinctly represent the national divide, but at the same time, they do no look uniquely one nation.

Okay, soherin follows a little pet cracktheory I developed while I was reading through The Promise comic. The following might be a bit spoiler-ish if you haven't read the comic yet.



This is Kori Morishita. She lives in the Earth Kingdom and her home is the Fire Nation Colony, Yu Dao. When the town started out, it was near nothing, but with the resources and help of the Fire Nation, it was built up into a major area over the course of a decade. Her father (a non-bending fire nation noble) came to the city to rule over it as Mayor and during his tenure, fell in love with an Earthbending native. Kori is an earthbender and Fire Nation citizen by birth.



This is her boyfriend, Sneers. He's a non-bending Earth Kingdom citizen.

Over the course of the story, the reconcile a difference and reinforce their relationship. They are vital in showing Aang about the future of the nations: they are no longer separate. It was important for his relationship with Katara, as well.

These two could very well be Mako and Bolin's grandparents. I don;t like for everyone to be related to everyone in series - I just think its a little limited and whatnot. Its a fun little thought, though. Even if they aren't.. I'm sure their family has a similar circumstances. What do you think about the bending brother's heritage?

What do you think about this bit of a crack-theory?

I personally think it's interesting. It's a little bit out there, but interesting nonetheless. Not to mention, it would give the relationship between Kori and Sneers that much more merit and depth. Their relationship would have quite a bit of relevance then.

This topic is too far back to really know. There is no real resemblance to their grandparents really, but that's skipping a generation, so they could look more like the married in parent. Really it all depends if their child actually got together yet another person from the opposing nation. I'm pretty sure if you made a heredity table for whether or not they'd be benders the way they are the chances of them coming out the way they did are very slim. Unless of course their child was a fire or earthbender and then they married the opposite and they were a fire or earthbender... It's too broad and too little detail to really know.

For all we know, Mako and Bolin may not even be blood brothers. They did say their parents got killed, but who's to say that their parents adopted them? If they died before ever letting them know they were adopted, Mako and Bolin would have no idea of it.
