In the original series, fifteen-year-old Sokka is a warrior of the Southern Water Tribe, a nation where some people are able to telekinetically manipulate, or “bend”, water.
The first known Chieftain of the Southern Water Tribe is Chief Hakoda. Sokka was placed in charge of the tribe in the absence of his father, Hakoda. Sokka was eventually made the official Chieftain of the Southern Water Tribe sometime after the Hundred Year War.
As frustrating as it is, the general consensus is that Sokka died of old age and natural causes between age 70 and 85. We first even learn about Sokka’s fate in the series sequel, The Legend of Korra (which you can watch on Amazon Prime, YouTube, and Google Play), when Katara says that he’s passed away.
Sokka is one of the few members in Team Avatar to seemingly have no children, so it’s unclear if he ever was (or stayed) romantic with anyone. The series never mentions if he was married or even if he had children, though if he did, fans probably would’ve heard some sort of mention from Tenzin about his cousins.
MAI. Mai is Zuko’s most consistent romantic interest. One of Azula’s only friends, she accompanies Azula on her hunt for Zuko and Iroh. She eventually helps bring down the Earth Kingdom and, when Zuko is given the credit for Aang’s defeat, is able to fully enter a relationship with the restored prince.
In the years between The Last Airbender and The Legend of Korra, Toph never married — but she did have two daughters from two different fathers. Her eldest, Lin, followed in her footsteps to become the stern yet heroic chief of police in Republic City.
He married Pema – a non-bender – and had four children with her from which all were air-benders – Jinora, Ikki, Meelo, Rohan. This guy is puzzling case. You would think that he married Sukki, right?
Each new Avatar’s primary bending style goes in the order fire-air-water-earth before beginning anew. This means the next Avatar will be an earthbender. The reason for this seemingly random ordering can be traced back to the very first Avatar, Wan.
Hope I made you proud. Bumi is Avatar Aang and Katara’s first child and eldest son, as well as the only one to be born a nonbender among the couple’s three children; he later developed airbending abilities after the Harmonic Convergence of 171 AG.
Unlike Kyoshi, Aang died of (mostly) natural causes at the relatively young biological age of 66, and was outlived by Katara by at least a couple of decades. Of course, because of his time spent in the iceberg he was actually 166 years old.
Sokka wasn’t killed off in the Legend of Korra. He died sometime before the events of the show. He was alive for Korra’s birth but never lived to see her master the elements. The show needed to show the new Team Avatar solving problems and going through life on their own.
Legend of Korra was criticized for the lack of an overarching plot but spent most of its run under the threat of cancellation due to the rapidly dropping ratings and explicit content.
It was later revealed that Appa was eventually sold to beetle-headed merchants, who in turn sold him to a Fire Nation circus where a sadistic trainer attempted to make him part of the show. Encouraged by a sympathetic boy, he later escaped and hurried back to the Si Wong Desert where he last saw Aang.
But Mei didn’t marry Zuko.
After her great achievements, Azula settled down and got married to a quite old nobleman named Yin Lee. She gave birth to two children, Chen and Mitsuki.
