The New Child

What if Katara was adopted into they Fire Nation and the person who adopted her was Iroh? Iroh the older brother of Ozai. Ozai had 2 kids, one daughter named Azula and one son named Zuko. Iroh just had one child named Lu Ten but he passed away when Iroh was trying to conquer Ba Sing Se. Iroh has been a bit sad when Lu Ten died so he decided that he'll adopt a child from the Fire Nation Orphanage. Ozai didn't agree but Iroh and Ozai's father Azulon agreed to have Iroh adopt a child.

(P.S I don't own any of the characters and this is just a story. There will be some cuss word so if you don't like that, I suggest you don't read this story. Anyways enjoy!)
