To a lot of folks, Avatar: The Last Airbender stands as one of the greatest triumphs in animation. It was a near-perfect story that blended action, heart, humor and a dense mythology accessible to everyone. Although its sequel series, The Legend of Korra, wasn't met with the same level of praise, it's still a solid entry in the Avatar series that many people enjoy. Of course, you can't be a successful show without accumulating some wild theories along the way, and with a fan base as passionate as this show's, you can bet there are some insane Avatar: The Last Airbender fan theories. 

Could bending just be the result of genetic engineering? Could Lin actually be the illegitimate love child of Toph and Sokka? Was there actually a very good reason why the live-action movie was so horrible? In this list, you'll find some of the wackiest fan theories about Avatar: The Last Airbender. Some you might agree with, others you might dismiss as totally nutty. Either way, check out the list below and be sure to comment on what your favorite The Last Airbender theory is!

    Lin is the Illegitimate Child of Toph and Sokka

    Google Toph and Sokka and you'll see all the fan art dedicated to pairing these two together romantically. For some reason, it is a theory that will never stop and Legend of Korra did nothing to quell the speculation. In the sequel series, we find out that Lin and her sister are actually only half-sisters with different dads, and we never find out who Lin's actual father is.

    Toph says her dad was some random person, but why even have them be half-siblings in the first place if the identity of the father wasn't important? People speculate that Suki perished in a battle sometime in the future and Toph was there to... comfort Soka. This led to the birth of Lin.

    Katara Was Supposed to be the Next Avatar

    This theory is all about pondering what would have happened if Aang wasn't frozen in ice for a hundred years. If, for some reason, he didn't run away and he managed to stop the Fire Nation from taking over the world, then he would have lived a long, extended life. When he passed, the next Avatar would have come from the Water Tribe.

    Given the timeline of things, this theorist is convinced that if everything progressed naturally, Katara would have become the Avatar after Aang. Who knows if that's true, but it's hard to doubt that Katara would have made a fantastic Avatar.

    The Horrible Live Action Movie is Actually an Adaptation of the Ember Island Players Play

    Almost any fan of the cartoon will call The Last Airbender live-action movie a complete abomination. It completely bungled every important aspect of the show and it's a point of contention amongst fans to this day. Hopefully, this theory can at least make the whole ordeal manageable.

    What if the horrible M. Night Shyamalan movie wasn't an adaption of the cartoon but rather an adaptation of the satirical Ember Island Players play the characters watched near the end of the series? It would explain how the movie got so many details wrong and solidify Shyamalan not as the guy who ruined any chance to see the cartoon adapted faithfully but as the master of twists who trolled us all.

    The Royal Fire Family Practiced Incest

    For those of you wondering why the Royal Fire Family seemed to be all-powerful with their bending, the true answer might be a little more Lannister-y to admit on a children's cartoon.

    This theory suggests that the reason the Royal Fire Family kept producing powerful Firebenders was because they practiced incest with one another. It's certainly not hard to believe that Emperor Azul and Emperor Ozai would be so obsessed with keeping their bloodline pure and powerful that they decided to "keep it in the family," so to speak.

    They would have done it to protect their firebending genes and preserve their legacy.
