''[[http://www.fanfiction.net/s/6982558/1/Avatar-Aang-and-the-Sorcerers-Stone Avatar Aang and the Sorcerer's Stone]]'' is a crossover FanFic of ''WesternAnimation/AvatarTheLastAirbender'' and ''Literature/HarryPotter''. It was made by [=AvatarCat12=] on May 5, 2011, and is still going. This adventure/fantasy FanFic is set two years after the events of the former series and at the start of the latter series.

In this fanfic, [[TheHero Avatar Aang]] and his friends are invited by [[TheMentor Albus Dumbledore]] to cross over into another world to attend Hogwarts School of Witchcraft and Wizardry. However, this strange new world is a lot for Team Avatar to explore and go on with their mission: to help Harry Potter, the other hero, defeat Lord Voldemort. They all encounter strange and new stuff in this new world...and their destinies stretch on further than they can imagine.

The author has confirmed that he is planning on making a sequel after this. And currently, it's completed.
!!This Work And Its Sequel Contain Examples Of:
* AlternateAnimalAffection: A rare case for humans in this fanfic. [[OfficialCouple Aang and Katara]] do show affection (such as kissing or hugging) to each other like any other humans, but they are also shown rubbing cheeks as cats would do and even licking each other's cheeks a few times.
** [[WordOfGod The author even says]] that they do this for affection.
* AttackOfThe50FootWhatever: This happens to Katara in ''Avatar Aang And The Chamber Of Secrets'' due to a harmless prank mixed with Lockhart not using the spell to shrink her. So they have to find a cure for her and shrink her back to normal size.
* BigBrotherInstinct: Sokka looking out for his friends as usual.
* BigFriendlyDog: Fang and Gin.
* BullyingADragon: This often happens.
* CharacterizationMarchesOn: Sokka shows some disbelief about magic. However, thanks to having gone through CharacterDevelopment in ''WesternAnimation/AvatarTheLastAirbender'', he learns to accept it quicker than before.
* EveryoneHasStandards: Aang loves all animals as usual...except for Fluffy.
* FantasticRacism: Malfoy and Pansy verbally attack Aang and Katara for being a couple despite being from other nations. So they try and force them to break up.
* FireForgedFriends
* TheHero: TWO of them, in fact!
* NoodleIncident: In chapter 20, Toph mentions almost getting Katara drunk only for the latter to quiet her down quickly.
* ShoutOut: Gin, Katara's dog, is named after the main protagonist from ''Manga/GingaNagareboshiGin''. In fact, he even looks like Gin!
** Part of [[spoiler:Kya's]] speech to Katara is similar to a scene from ''Disney/{{Bambi}} II'', when Bambi sees his mother in a dream.
** In the Quidditch chapter, Sokka exclaims randomly "You want the truth! You can't handle the truth!", just like from ''Film/AFewGoodMen''.
** Katara attacking Dudley and his gang for attacking Aang is similar to ''Disney/TheLionKing'', where Mufasa attacks the hyenas for attacking his son, Simba. The dialogue that Katara and Dudley's gang have is also similar to the dialogue Mufasa and the hyenas have.
** The druid who travels with Firenze is a ShoutOut to ''VideoGame/WorldOfWarcraft''.
* SnowMeansLove
* TeamPet: Appa and Momo return to fill this role again. Also, Hawky, who hadn't been seen since the ATLA episode ''The Runaway'', makes his return. Not only that, but two new pets arrive: Gin the dog and Boulder the toad.
* TheBusCameBack: Hawky returns to Team Avatar after his debut appearance in the episode ''The Runaway''.
** Kori Morishita from ''ComicBook/AvatarTheLastAirbenderThePromise'' came back after her appearance in the sequel.
* ThoseTwoGuys: Sokka and Ron.
* TrueCompanions
* [[spoiler:VillainTeamUp]]: [[spoiler:Voldemort and Ozai]] team up in the epilogue of the story.
* ViolentlyProtectiveGirlfriend: Katara shows Dudley and his gang what they get for [[spoiler:attacking Aang]].
* WouldHitAGirl: Sokka attacks Pansy for attacking Katara and insulting Kya, but he does this for a good reason. He even lampshades this by saying this:
-->'''Sokka''': Normally, [[WouldntHitAGirl I won't hit any girl]]. But for this bigmouth, I'll make an exception!
