The Stalking Zuko Series

Stalking Zuko is a well-written Adaptation Expansion fic that acts as a between/behind-the-episodes look at Avatar: The Last Airbender. It starts off when Zuko is accepted in the Gaang - Katara doesn't trust him and fears that he will backstab them again. Her solution is to stalk Zuko and write down his every action so she would know his weakness. The story follows the Gaang's adventures throughout the second half of season three - retold through Katara's perspective.

Has a pair of sequels in Not Stalking Zuko and Not Stalking Firelord Zuko and a prequel with Jet's Troubling Obsession.

Trilogy Creep: Has three parts with Stalking Zuko, Not Stalking Zuko and Not Stalking Firelord Zuko.
Tsundere: Katara is Type A. Justified, as Zuko was formerly their enemy and Katara doesn't trust him to not betray them. Katara is initially very hostile to Zuko until they become friends and Katara realizes her feelings for him. Then she is no longer this trope when she is crushing on him. Slightly deconstructed when Zuko gets worn out by her hostility and believes them not to be friends.

Zuko, I Am Your Great-grandfather: Played with and mocked. When Zuko revealed that Avatar Roku was his maternal great-grandfather, Aang realized that would make him Zuko's great-grandfather. Then Aang proceeds in asking his "grandson" for hugs.
