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 perfectly 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 enjoyed. Of course, you can't be a successful show without accumulating some crazy 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!

It isn't hard to realize that the geography of Avatar is vastly different than our own, but what if that was intentional? This theory suggests that the entirety of Avatar: The Last Airbender actually takes place on another, smaller planet than our own. It would explain how everything is so close together and it would mean significantly less gravity.

Presumably, less gravity would explain how the characters can jump so high and maneuver in the air so gracefully. A smaller planet might also somehow explain how there are huge animals, like lion turtles, roaming around.

One eagle-eyed viewer was such a big fan of Princess Azula that they started noticing something odd. While watching the show, this theorist realized that Azula is probably left-handed. A majority of her lightening attacks come from her left hand, and when she finally breaks down in the last episode, she throws her hairbrush with her left hand at the mirror.

It's a minor theory, but it reinforces the entire "Azula is a prodigy" angle that dominated her storyline. It also proves that the show was focused even on the tiniest details, which is what helped make it so perfect.

When the first Avatar, Wan, started his adventure, the very first spirit he came across was Aye-Aye, a lemur spirit. At first, Aye-Aye was hesitant of humans, thinking they were nothing but savages who wanted to eat all the animals and destroy his home. Over time, Wan and Aye-Aye learned to trust each other and became good friends.

This theory posits that everyone's favorite Lemur, Momo, is actually the spirit Aye-Aye reincarnated. It would explain Momo's above average intelligence and his fierce loyalty to the Avatar.

When you look at World War II and the The Last Airbender, it's not hard to see the parallels between the two. In the war, a Germany fueled by nationalism began conquering all of Europe in an effort to show their superiority. In the show, the Fire Nation started a war for a similar reason and even wiped out an entire race of people. The Nazis were defeated by three large superpowers - the United States, Great Britain, and the Soviet Union - a tidy parallel to the Water, Air, and Earth kingdoms. 

It's a well-known and completely plausible theory that The Last Airbender was an allegory for WWII, but not much discussion happens around the idea that Korra was actually a reference for the Cold War. In the end of the first season, Amon was basically a communist who wanted to make everyone equal, while he considered himself superior. It's similar to what happened with Joseph Stalin and the rise of communism in the beginning of the Cold War
