That capability is later abused by Yakone’s son Amon, who targets benders in Book One.
Other past Avatars shown onATLA,including Roku and Kyoshi, also make brief appearances inKorra.
Sokka
Like Aang, Sokka dies beforeLoKbegins.

Nickelodeon
We learn Toph set up a metalbending academy and, eventually, the metalbending police force in Republic City.
She acted as its chief and, down the line, Lin serves in the same role.
And like with Aang, audiences find out the now-elderly Toph was far from an involved parent.

“Didn’t work.”
Still, we wish we could’ve seen a scene with Zuko and Iroh.
Iroh
Speaking of Iroh, everyone’s favorite uncle is back dispensing more wisdom inLoK.

Nickelodeon
People won’t stop abusing his library’s knowledge for evil.
Ultimately though, he sides with antagonist Chief Unalaq due to the waterbender’s close relationships with the spirits.
Fans will be happy to know that his fortune turns around following the events ofATLA.
