Because there's no story reason for it?
Avatars can channel more than one element at once outside the Avatar State.
No, he didn't.
That has nothing to do with the movie?
No, he didn't.
Azula for me, as well.
Pretty sure it's just because he's emo.
You could say that about every fight in the series.
And Ozai doesn't?
"Okay, true but..." *insert random thing that doesn't actually answer the question*
You didn't answer the question, man, and hair color proves literally nothing.
Ozai.
I didn't say you edited it, I said it was edited.
It's a meme.
Presumably, neither the original post no 'Nickelodeon's' reply exists, and if they do, that's clearly not Nickelodeon's official account.
Dude, that's clearly edited. -_-
He already controlled Ba Sing Se and there was no reason for him to kill the Avatar.
Good genetics.
Not that much to it, man.
That would put him in the public eye.
As shown by Azula, you can overthrow the Earth King anytime if you control the Dai Li, which he did.
Did I say he could beat her or did I say even ground?
Considering that Zuko was able to put up a much better fight against Azula while escaping from the Boiling Rock than in all their other battles, I would disagree.
