to be honest people for once i want to see the adventures of a fully realized Avatar , no more learning , no more training, nothing ,just an Avatar doing his job as he has to , simple and beautiful, and yeah i want to know who did Toph marry

But what can the previous Avatar really do to the current one besides talk to them?

I do not think there has ever been a set number of Avatars. I do not think we will get one. We know the Avatar has been reincarnating since the era of bending elements and has had over a thousand life times. It would get confusing if the writers try to back track and categorize every Avatar.

Well Aang was able to energy bend Korra maybe there are other things that can be done

I doubt there is a dark avatar in the line it would have broken the cycle. A dark Avatar can work an Avatar of Chaos of sorts. Something like Dark spirits locked away by the first Avatar.

Glad my recollection of the Dark Avatar is fueling some good discussion!

The idea that the Dark Avatar is an entity outside of the regular Avatar cycle makes more sense to me than having an Avatar who went dark. Maybe the spirit had been locked away in the Spirit World and somehow gets free. The shadow-/lightbending is another idea from Gantros' thread that I really liked. It gives Korra something new to learn to combat the DA.

What it all boils down to, I guess, is that since Korra is a complete Avatar now, something like the Dark Avatar, who is equal and opposite to her in every way, is the only logical threat. Even if Amon had returned, bloodbending would no longer be a problem for Korra, as we saw Aang rather effortlessly dispatch of Yakonne earlier in the season. Hopefully, Bryke is (are?) on the same page.

How can we be so sure Korra is a fully realized Avatar? I am sure that was how the ending was intended to be when it was just a mini-series, but do you think next season will have Korra fully trained as the Avatar with mastery over all four elements including air and totally control of the Avatar State? She just opened up to her spiritual side. She shouldn't have control of the Avatar State at this point.

I could go with a Dark Avatar storyline if done well. I would like to go into more of what the Avatar spirit is and its history. Has the Avatar always been born into humans or was there a time where it was a spirit that protected the world like a god or something?

I wouldn't mind knowing about the previous avatars you can't tell me that if there were thousands of them none of them ever figured out a new form of bending until Aang learnt the originalenergy bending.

I'm just gonna say that a "Dark Avatar" sounds incredibly silly and I really hope it never happens.

What kind of relationship do you guys think we can expect from Aang and Korra in this series? She has become more patient, but I cannot see Aang's solemn advice always being appreciated by Korra, similar to how she at first with Tenzin.

I am happy that Bolin will get character development. His character was really shallow, but he has potential. I understand why his character wasn't developed in the first 12 episodes, since it was meant to be a mini-series, but now we should really see some good character development.

Maybe instead of power vs power we can have Korra a fully realized Avatar having to fight like a genius strategist. No human can go head to head with a fully realized Avatar. The Avatar just has too much raw power. I can see why a concept like the Dark Avatar is appealing, because in theory it would have power to match the Avatar. Instead of having dumbasses like Sozin and Yakone who boldly challenge the Avatar head to head we have a villain who always has a plan and uses Korra's power against her or explioting other weaknesses of hers. We have another villain who is light on his feet.

It would appease more people who do not like the idea of a negative Avatar or some new bender who comes out of nowhere and is somehow as powerful as the Avatar.
