The best reason for Zutara I think I've ever heard.

In which young Zuko disapproves of "Love Amongst the Dragons" (the tale of Princess Soza, Avatar Kuro, and a love that was never meant to be)

In which Zuko attempts to have fun, and Sokka's burgeoning new career comes to a screeching halt.

A flash of temper means a different ending to an Agni Kai. What would happen if the battle between Zuko and his father had gone another way? An AU version of the events of "The Avatar Returns".

In which Sokka muses, Jit Sang has a very sharp knife, Hakoda braids his beard and mediates, Aang shaves expertly, Zuko rejoins the Ponytail Club, and Haru nearly cries, to the amusement of all. Post Boiling Rock. Fluffity!

Fifty one-sentence chunks of an Avatar/FMA crossover. Basic idea is that after some implied (non-canon) craziness in Amestris, Ed and restored!Al find themselves lost in a desert, under stars they don't recognize and with only the vaguest memories of how they got there.

Fourth Year Toph Bei Fong holds the record for the most detentions served by a single student in five hundred years of Hogwarts's illustrious history. She has a tattoo, regularly gets illegal paraphernalia from Hogsmeade, and is proud of being the reason for every last one of McGonagall's gray hairs. She's also the single most hated person in the whole school.

The Ember Island Players did him a favor, really, when they took their show on the road.
