Foe Yay/Western Animation/Avatar: The Last Airbender

Where to start with Avatar: The Last Airbender?

"Katara: Aang! How'd you get that? (referring to the necklace Zuko stole from her) Aang: Zuko asked me to be sure I got it to you. Katara: Oh, that's so sweet of Zuko. Could you give him a kiss for me when you see him?"
 * Zuko's three-season-long undaunted obsession with capturing Aang. Avatar was never much for subtlety.
 * Back in the first season, this conversation between Katara and Aang at the end of episode 15:


 * As can be seen hilariously concluded here
 * In the third season, there's an episode about Aang's and Zuko's predecessors, Avatar Roku and Fire Lord Sozin, who started out as friends... best friends! All their lives! Who shared a birthday! And Sozin didn't get married and have kids until way late. Come on. You just know he only wanted to conquer the world to win his true love Roku back. Too bad Roku was straight, really. So much tragedy could have been averted. If you think about, this makes the fact that hilarious.
 * Jet's behavior towards Zuko in "City of Walls and Secrets" -- the observations of a Well-Intentioned Extremist, or the obsession of a Stalker with a Crush? Hey, eighteen thousand Slash Fics can't all be wrong!
 * It's a good thing Zhao was dead long before this page existed, since the reason a guy who thinks he's destined to kill a god develops such a personal rivalry with a teenager is never explained... Oops!
 * And then someone made a Zhao/Zuko-themed remix of the Hark! A Vagrant comic on the Foe Yay page...
 * Zuko and Katara in "The Waterbending Scroll": "I'll save you from the pirates" indeed. Many a Zutarian, crazy and sane ones alike, have pointed to this scene as the one that officially launched the ship that would take over a large portion of the fandom, for better or worse. Many female viewers can't hear that line without wanting to squeal "You can save ME from the pirates, Zuzu!!!!!"
 * Three Words: North Pole Fight.
 * Azula and... just about everyone. Aang, Katara, Zuko (especially Zuko, or as she calls him, "Zuzu"), Long Feng, Sokka, Suki... and she only gets this with after they betray her. Really, Azula owns this trope.
 * The really funny thing about Azula's Foe Yay is that it seems to be almost unintentional on her part- the one time she actually tries to seduce someone, it fails spectacularly. We Can Rule Together, coupled with flaming hands and a psychotic smirk, apparently doesn't make for a good pick-up line... unless you're using it on your older brother.
