Started S3 Book of Fire.

C1 to C5 The Fire Nation royal family kids all got some issues. They've got a guy that basically shoots canons without doing any body motions. The 3 eyed cyborg.

Sokka grown up to be a great tactician and leader with good commanding skills. And he got his Nichrin sword too.

Toph is ride or die. Katara has grown to be a great leader amd water bender.

They are all normal people. The people of Fire Nation. Expected them to be tyrants but they all are forced in a war, their culture is being diminished and their lands polluted.
