According to the Legend of Korra, Zuko, the former Fire Lord, eventually had children. Although the exact number of his children is not explicitly mentioned in the show, we do know that he had at least one daughter named Izumi.
In the sequel comics, specifically in “The Promise,” it is revealed that Zuko became the Fire Lord after the events of Avatar: The Last Airbender and ruled the Fire Nation for many years. During his reign, he had a daughter named Izumi.
Izumi eventually became the Fire Lord herself and had two children of her own. However, their names and further details about them are not provided in the show or the comics.
It is worth noting that these details about Zuko’s family are only briefly mentioned and not extensively explored in the series. The focus of the story primarily revolves around the new Avatar, Korra, and her own journey. Therefore, the information about Zuko’s family is not as prominent or central to the plot.
As for personal experiences, I have not had any direct experiences with Zuko or his family, as they are fictional characters from the Avatar series. However, I can understand the curiosity surrounding Zuko’s family and the desire for more information about his children.
To summarize, Zuko had at least one daughter named Izumi, who eventually became the Fire Lord herself. Izumi had two children, but their names and further details are not provided in the show or the comics.
