THIS IS THE MOST PERFECT THING EVER! OH my word, I just finished Avatar: the last airbender" and I'm still crushed that it's over! So of course I'm going to go crazy with fanart and stuff. But anyway, thank you so much for making this!!
No its on the Avatar Wiki and also I read some where it was in the comics that they broke up. They are still doing more comics so there is a posability like you said they they will be back to geather but for now its canon that they are not. I hope that it wont be canon for long.
Oh yeah actually that's all I meant is that they broke up in the comics but I don't think that means they won't get back together since they have in the past. c: I know, I really love Maiko too.
They haven't mentioned Zuko at all in Legend of Korra yet so I don't actually know what happens but in the game on the Nickelodeon website it does say that Zuko travels as an ambassador for peace. And also there is a statue of him in the middle of Republic City. Doesn't say anything about his relationship though. At least we know it's not with Katara ;D
The show ends with them together, however, there's a comic series called "The Promise Part 1" which takes place right after the last episode. As of right now, Mai and Zuko have broke as neither Michael Dante DiMartino or Bryan Konietzko have said anything about them ending back up together. Of course you can assume that they do end up together in the next comic, but technically, no...as of right now. (Part 2 will be about Zuko's search for his mother)
