Finally, we met again!
I was planning to rewrite some headings in this blog. I believe Zuko is also like an Avatar. He learned from all types of benders and improved his firebending skills. Have you seen Zuko using a fire wall against Azula, similar to how Katara used a water wall to block her grandmother's ex-lover's attack? That scene happened when Katara visited the Water Tribe in Season 1.
