I'm pretty sure he will here's what a web site said
At some point, Zuko had a daughter. He continued to remain in power until 167 ASC; at the age of eighty-three, Zuko relinquished the throne of the Fire Nation to his daughter and officially retired, although he continued to travel the world as an ambassador for world balance, albeit in an unofficial capacity. A statue of Zuko was erected in his honor at the center of the Central City Station in order to commemorate his many accomplishments link
in one fanfic i read called "Fall of the White Loutus" (it was an AMAZING Zutara fanfic) this story was mentioned in the epilouges authors note. Katara was on her way to teach Korra and Zuko had died 2 years earlier.
It's been confirmed that everybody in Team Avatar will be dead unfortunately.
Though there is an episode in The Legend of Korra that will have something to do with Zuko.
There is also a possibility that he will appear in some flashbacks.
but if king boomi was still alive when aang came back 100 years later he was still alive so zuko might still be alive... and zuko was 16 in the old avatar so he is only 86 and people in avatar live for a long time...
I'm guessing yes because in the first episode there was a firebending guy that i think is him/no because the guy didn't have the scar/but it could have gone away over the years.p.s the first episode is on www.nick.com and katara is still alive as tenzins kids' gran gran
actually he probably will be if you play the republic city point and click game, it says that one, hes still alive, and two,he gave control of the fire nation to his daughter and travels the world trying to create balance. so yeah i assume he will show up, he will be like 87 though.
I checked the avatar wiki and it said he is still alive in The Legend of Korra so I think he will show up, I hope he goes see the Fire Ferrets fight and Katara goes to and points out Mako and says he reminds me of you cause that would be interesting if there ended up being a reason for that. Man, I talk a lot.
yes He will be in the legend of korra because 1)He is still alive and is 87 years old in legend of korra 2)It says on the website Dante Basco voice actor of Zuko will be making a come back in the avatar series Legend of korra he will be represneting the character zuko or a character thats related to him in a way so got to wait till new episodes ^.^
He might he is still alive in the little game they have on there page it says zuko resigned from fire lord and let his daughter take over now he is traveling the world and will probally be shown in The Legend Of Korra
It was established that Zuko is Still Living and has retired as Firelord, having abdicated this to his daughter who is the current Firelord. (firelady?) he as been traveling to the other nations as an ambassador, perhaps we will see a reunion as he makes an appearance visiting an "Old Friend" - Katara, who is also alive and well.
