As "The Legend of Korra" Book 3 looms ever closer, rumors regarding Zuko, his daughter, and the fate of other characters in "Change" have surfaced.

Popular theories are currently running very hot for "The Legend of Korra" Book 3, and one of the top questions being asked is whether a major character will die this season.

Although the series is geared towards a younger audience and no major character has died on-screen during "The Legend of Korra," there is one character many suspect could die—Katara.

As Book 2 fans know, a major storyline involved introducing and bringing together Aang and Katara's children. Now that great harmony exists within Katara's lineage, it would make sense conflict-wise to introduce a tragedy such as the passing of such a beloved character.

She is also by far the oldest recurring character on "The Legend of Korra," so Book 3 may be her time.

Another rumor which has been greatly explored ever since the teaser leak for Book 3 is the return of Zuko.

"I think it's safe to predict that he'll play a role," says Emergency Awesome. "Hopefully he will be helping Team Korra, but we really need an official trailer to be sure."

"The Legend of Korra" co-creators Bryan Konietzko and Michael Dante DiMartino have confirmed that much of Book 3 will take place in the Earth Kingdom and the Fire Nation, so how much we see Zuko could depend on how much the Fire Nation plays a role in "Change."

But one character who will most likely be seen regardless of whether Zuko makes an appearance is his daughter, the Fire Lord of the Fire Nation.

"There are women world leaders in the Avatar world during Korra's present: Zuko's daughter is the Fire Lord, and there is an Earth Queen ruling the Earth Kingdom," writes Konietzko on his Tumblr.

Could "The Legend of Korra" Book 3 reveal Zuko's daughter?
