Harmonic Convergence did not 'create' new Airbenders, it just awakened latent power. In a way, it jump-started the bending potential of non-benders.We know that Bending is transmitted by blood. Previously I had read that bending was more cultural but Legend of Korra show several characters of mixed origin. Fittingly, the major set of mixed siblings all display a variety in their elements. Mako and Bolin are brothers yet one is a firebender while the other is an earthbender. Aang and Katara's children are also a similar case; one is a waterbender, one is an airbender and the third was (previously) a non-bender. Isn't it just the neat little coincidence that Bumi, the child of the former Last Airbender just so happen to suddenly become an Airbender himself? My theory is that harmonic convergence 'jump started' the untapped bending potential of individuals. But you may be wondering; what about all those airbenders all over the world? Their dad wasn't Aang. Well, see, Aang may have been the Last Airbender but I find it dubious he was the only one with Air Nomad blood. I mean, come on, let's be realistic here; surely there were people who had Air Nomad ancestry somewhere in their family tree. Even if it was as far as a dozen generation behind. So, what hapenned is this; some (all?) the non-benders who had Airbender blood, no matter how thin, received a boost that was just enough to activate their distant and latent airbending. It didn't work on the people with Air Nomad blood who already had bending because only the Avatar can bend more than a single element.
There will be a hidden Airbending cultureJust like the Sun Warriors in Avatar: The Last Airbender , the will be a tribe of ancient airbenders hidden. They will be called the Sky Barbarians, they will be based off the Mongols, they will have Canadian accents (there's waterbending rednecks, so why not?), and they will have been plotting world domination for decades. They will invade Republic City at some point. They will be the polar opposite of the Air Nomads, preffering violence over everything else and using all dangerous airbending techniques like tornados, hurricanes, choking people, venemous-gas/fart bending, soundbending and lightbending. As it turns out, Korra will have a dillema. To save the world, she'd have to commit genocide.
The invention of guns will appear
Despite the high technology, guns will not' make an appearanceThe creators want to keep the show kid friendly and know it would be too much of a Game Breaker in terms of story telling.
The Show will have some proto Cyber Punk elements
Going with the gangster theory, the show will potentially involve immortals.Hey, taking place in a 20's-esque setting. Although there is the potential of an overload of awesome.
The play performed by the Ember Island Players has gone on to become an all-time classic, with the original ending substituted for the actual ending of Aang beating Ozai.It's a national treasure of the Fire Nation and is performed all around the world.
A lot of waterbenders will function as doctors.And boy, they will cost much. Also, imagine what kind of sickness they could cure if they're using actual medicine instead of water. It worked so well and fast with regular water! They will certainly cost a lot. Maybe Katara opened up a medical school when she was younger?
Silent film now exists in the Avatarverse.Well, this is apparently set in their equivalent to the twenties, so why not?
Pro Bending will become fakeProfessional Wrestling started out as a legitimate fighting sport, but gradually became more scripted, until it eventually became the totally fake exhibition performance it is today. Pro bending seems to be going the same way already, what with the Wolfbats' pyrotechnics-laden entrance and heelish antics, the coslaying fans, etc., so it may very well become increasingly staged as time goes on to keep the fans' interest, after all- not every fight can have the Avatar in it
One word: SteambendersHey, cultural melting-pot city, fantastic, almost unimaginable technological progress...perfect setup for the formation of a new form of bending. A special subform at the very least, or an entirely new "hybrid" discipline at most/worst. Plus, goggles. Gotta have the brass goggles.
Iroh's Jasmine Dragon will be the new Starbucks.Wouldn't it be funny to see people walking around Republic City drinking tea from Jasmine Dragon labeled paper cups?
The Fire Nation will be a rustbelt and declining power.
Agni Kai will be illegal in Republic City. It will also be seen by many as an anachronism.Historically, as societies become less feudal and the rule of law becomes more important, judicial combat declines and is eventually outlawed. The agni kai will be treated the same way in Republic City. The popular perception of it will be less "means to avenge wounded honor" and more "excuse for vigilante brutality". They'll still occasionally be fought, mind you, but they'll be relegated to the shadows, like street racing is.
We will see the rise of new spirits.There are already forest and nature spirits, and so machine and city spirits will arise, the city spirits' rapid expansion will clash with the nature spirits, forcing Korra to become more spiritual to mediate a compromise, meanwhile machine spirits will arise and will be prayed to similarly to the Adeptus Mechnaicus in Warhammer 40,000 as well as delivering fortune to those who properly maintain their machines.
Benders in Republic City will be expected by custom or law to wearing something identifying themselves and their element.With the end of color-coded clothing, and the intermixing of peoples meaning eye/skin color aren't even useful as a rough indicator in Republic City of someone's elemental background, benders will start wearing tokens to show their alignment. This will take two forms. First, something like a colored scarf (a la Mako's neck one and Bolin's waist one). Second, it might be a piece of jewelry, like a sun or moon necklace. But whatever the case, it'll be something worn on top of a regular outfit.
There will be a countercultural element in the United Republic that mocks the traditional cultures of the Four Nations.Alongside the bender/non-bender divide, there will be a conflict between the United Republic of Nations and the other four countries. Among the older generations, like Chief Beifong and Tenzin, the United Republic is a place that can be broken down into "tribes" that fall under the regular Four Nations. They'd see Mako as being a wayward son of the Fire Nation and Bolin as that to the Earth Kingdom. In contrast, the younger generations will simply see Mako and Bolin as citizens of the United Republic, and the fact that they bend is distinguishing in a way that whatever element they bend is not. As a rebellion against the "tribal" framework more traditionalist folks impose on them, Republic City's counterculture will purposefully adopt foreign elements as a way to mock them for being hollow symbols in a 'modern' era. For instance, a firebender might wear his hair in a Water Tribe wolf's tail, or a non-bender might wear clothes cut in the style of the Fire Lord. Some other countercultural types will take it a step further by doing such things as wearing their robes right over left and decorating with intentionally bad feng shui.
The United Republic of Nations has begun taking the Avatar's job.The Fire Nation started the war during a period when the Avatar was too young and too inexperienced to stop them. As a result, the Republic was given special diplomatic and military powers so that they could act in the Avatar's stead while an Avatar is growing up and training. In keeping with the Romanticism Versus Enlightenment themes of the series, some of them are starting to wonder if the Avatar is now superfluous.
Pacifism will be a popular global philosophy.Pacifism, once the domain of the Air Nomads, will have become a popular global philosophy owing to Aang's energybending of Ozai and his general behavior in ending the Hundred Years' War. However, the Avatar-verse's definition pacifism will be a bit different from what we think of it, as the go-to model will be Aang. So it'll be more of a militant or technical pacifism. Which isn't to say you won't have different ideological flavors. Killing will always be right out, but there will be disagreements about how far to take non-lethal injuries in a fight. Some will see energybending as an endorsement to cripple or maim (but not kill!) opponents to ensure they are no longer a threat. Others will see violence as only necessary in combat or training for combat, meaning some pacifists will protest against Pro-Bending as idealizing violence. Others will even view Aang's militant pacifism as an unhappy yet necessary concession to the dystopic state of the world at the time of his defrosting, but, now that the Hundred Years' War is long over and the world is largely peaceful, believe that strict pacifism should be practiced lest people slide down that slippery slope of justifying violence with technical pacifism.
The pro-bending championship is fixed.In crime-ridden Republic City, organized crime just has too much money at stake when it comes to the big pro-bender championship. So the high-end matches are fixed; sometimes outright, sometimes just for the point spread. Except now that the Avatar is involved with a team aiming for the top, asking the Fire Ferrets to play along nicely isn't really an option, so the squeeze is gonna be put on Bolin or Mako to stay silent and comply with the mob's orders lest the other brother get hurt.
The Boulder is one of the pioneers of pro-bending
The Southern Water Tribe primarily uses a barter system.Hence, why Korra thought she could still get by in Republic City and tries to purchase food without having any money, the logic being that there were plenty of favors she could trade, being the Avatar.
Mixed marriages are not as common as we've been led to believe.Tenzin, the son of a Air Nomad father and a Water Tribeswoman mother, married a woman of an unknown ethnicity and Mako and Bolin are brothers of mixed heritage. But just because the war is over doesn't mean everyone's all buddy-buddy now. Outside United Republic, mixed marriages are still rare and frowned upon.
There will be new forms of Bending due to Aang's EnergybendingHe'll eventually give Ozai's bending to a bender of a different element after being pressured into an experiment. After a huge success wherein the two forms of bending combine (think lavabending if it's an Earthbender for example) instead of being controlled separately (because only the Avatar can do that), other Benders line up to have their powers mixed and matched. Eventually hundreds of Bending forms are spawned and taught around the world, even to nonbenders who are training to receive the ability to bend from Aang (cause you know, he can do that with Energybending). If this happens it'll probably be an attempt at recovering from the [very well done] Ass Pull that is Energybending, but I'll be damned if it won't be awesome all the same.
The glowy light show that Aang pulled off with Energybending? That's just what it looks like from the perspective of the bender and their target.Witnesses just see it without the light show, akin to what Amon did.
The gangs of the city stem from varying post-war attitudes.We've got the Agni Kais, the Red Monsoons, and the Triple Threat Triad. To go in reverse order, the Triple Threats are (as we know) made up of allied earth, water, and fire benders. Clearly, then, the founding firebender didn't have any issues with fraternizing with people from other nations, and would have likely been considered a sympathizer by the Fire Nation during the war. The Red Monsoons is a step away, being allies of water and fire benders. The founders, for some reason, didn't like earthbenders. The one with the biggest red flag are the Agni Kais. Just from their name, it's pretty obvious that they're some sort of Fire Nation nationalist or supremacist group. The other gangs, then, would be varying mixes of earthbenders and waterbenders.
The Equalists will create their own monster.Ok, there was speculation above that this series is just a set-up for another series that will parallel WWII. However, there's one problem with that: The Equalists seem to represent Communism (an extreme version of "equality" that leaves no room for accomplishment through natural talent), and we weren't fighting Communists in WWII, we were fighting Nazis...but wait! Prior to Hitler's rise, there was a strong Communist presence in Germany...in fact, many people voted for Hitler who otherwise wouldn't have been, because they thought he was better than Communism! In the same way, the Equalists will lead to the rise of a faction dedicated to the extermination of all non-Benders, forcing the sequel series (of which Korra will still be the star, there's no way they'd have time for her to die, and the next Avatar to grow up) to fight a war both for freedom, and for the very survival of non-Benders.
The 36 Levels of Airbending will finally get explained or shown in fullUnlike the other bending arts, Airbending specifically had a series of trials one had to undergo to affirm their mastery. Aang being the brilliant little punk he was, was so good his invention of his signature Air Scooter promoted him to Master one tier early; marking him as the youngest official 'Master' level Airbender in history- and coincidentally, relieves the need to display his native training and focus on the training of the following Arts. Perhaps during Korra's ongoing lessons with Tenzin we will finally see what it is that these 36 Levels are, and what was the last step Aang didn't have to do. Heck, it'd be really cool to see her do as her predecessor and make a distinct technique all her own.
The "Advanced Airbending" will be SoundEach of the other elements have a sort of "advanced" version. Water becomes healing and bloodbending, fire becomes blue fire and lightning, and earth becomes metal. Korra, Tenzin, or one of Tenzin's kids will advance Airbending to the point where they can bend sound.
Alternatively, the advanced version will be VacuumbendingBasically, the ability to create vacuums, which can be used to pull air into a concentrated form to be shot out(air bullets, or even air blades), and it could be used defensively by sucking in attacks thrown by other Benders. It could also be used to suffocate people by creating a vacuum field around the victim which sucks the air away.
The Airbender population will not be replenished solely by Tenzin and his family.Through spiritual enlightenment and practice, airbenders will begin to be borne spontaneously to nonbender Air Acolyte couples.
Benders will adopt Equalist weapons.Everyone can have the power of a chi-blocker in the palm of their hand... including benders. Imagine waterbenders electrifying their water whips, or metalbenders with a shootable tazer built into a glove. Not to mention dual-wielders like Zuko who will combine their bending and their shock glove to have varied short- and long-range attacks.
It is illegal to bloodbend in Republic City.Given Yakone's work bloodbending 42 years ago, it isn't much of a stretch laws were enacted against this form of bending being used due to its massive cruelty potential. That is why Tarrlok asked his secretary if the other members left before dismissing her so nobody would catch him using it in combat against Korra.
In another hundred years, pro-bending will have four-man teams, with the fourth member either an airbender or a nonbenderIf the guess about the air acolytes getting airbender children is right, there will probably be a few hundred airbenders running around in a hundred years. It would be hard for the pro-bending sport to ignore that. However, even with a few hundred airbenders, there likely won't be enough willing to join the competition to require one in every team. Instead, teams can have either an airbender or a non-bender. In order to maintain a bit of balance, non-benders will be allowed to use a shield and a stick with a weighted end. Airbenders will get limited in that they can't spend more than a second off the ground, as well as not being allowed to channel air for more than a second (like waterbenders)
The Kyoshi warriors have or will learn their own unique style of waterbendingCurrently, the kyoshi warriors do not appear to have any benders on their island. However, they do live nearby a mystical creature that spews water. Many of the bending arts were originally learned by observing animals. You do the math.
Republic City is facing an Evil Versus Evil ScenarioAs of Episode 8, we have The Good, the Bad, and the Evil. Korra and co. are the good.
There will be sky pirates.We've seen that zeppelins are fairly common in and around Republic City. It's probable at least one got into the hands of some less-than-honorable people, who now go gallivanting around the world stealing whatever they want and escape in their zeppelin. As an added bonus, the Steampunk crew will be a mixture of water and fire benders.
There will be tanks, bi-planes, destroyers and bombsIt is the Roaring Twenties. By this time in the real, all these had been invented. We already had a lot of cool tech in ATLA, so we will have
Republic City will become the setting for a World War-esque conflict and a Great DepressionIt's the best way to give Amon a chance at removing the world of as many benders as he can - get them in one place. So maybe his assault on the City will force the Krew to call for assistance from the 3 nations. Even the Order of the White Lotus will have to join the fight. If he could pull off the impossible and keep winning (for a while at least), he would collect mass POWs and de-bend them all. We have a city in the Roaring Twenties without a war so far so if the Season finale promo is any hint, things are about to get much, much worse. Benders are the backbone of the city's industry, if they lose their bending, the industry will collapse. Not to mention that Sato, the biggest industrialist in the city is on the enemy's side. If he goes, his empire goes with him. Since we don't see a Stock Market in town, this would be the best way to introduce it. Then the criminal gangs will go on mass looting through the city, and the krew will have a major clean up job on their hands, assuming all of them survive with their Bending intact.
The next series will be set After the EndGiven the longevity of Avatars and the rapid pace at which technology is advancing in the Avatarverse, by the time Korra's successor is born we'll get either Avatar in Space or Avapunk, which would be stretching things a little too far in my opinion. By the time the next Avatar comes around, a huge cataclysm, be it global war or a meteorite impact, will have reduced most of the world to a smoking wasteland and set back technology decades or even centuries. Alternatively, we'll get a Prequel.
The United Forces is a small armyAfter the world finally had peace, the former bending nations didn't want any army to become to large to avoid another war. The United Forces was set up to be peace keeping force, just big enough to keep all the nations inline, but small enough to not be a threat against all the other nations on it's own. Sadly, this meant that they don't have that many troops to fight Amon.
Water Tribe noodles are made with alcohol.How else can anyone get drunk off noodles? Perhaps it is boiled in sake?
The majority of the water benders in the city are decedents of the Swamp water tribesThe majority of the northern and southern water tribes have very dark skin, yet all just about every water bender we see (barring Korra) in Republic city has much lighter skin tone. The only water benders we ever saw that had anywhere close to that light of skin was the Swamp people. It would make sense, since most of the other waterbenders would find the heat of a city so close to the equator discomforting. Korra doesn't mind, since she also is a firebender (who can't firebend in extremely cold places).
Dragons really are dead now.With only two members of their species left during the only time we saw them, they're very likely extinct.
The Northern Water Tribe no longer practices arranged marriages.Back in ATLA, arranged marriages were normal for the NWT, and the marriage/betrothal age was 16. This was a case of Values Dissonance even for Katara and Sokka, who were from the Southern Water Tribe. Arranged marriages didn't seem to be the norm anywhere else in the world, even for prominent families like the Bei Fongs and the Fire Nation royal family. Arranged marriages will be seen as very bizarre and backwards in Republic City. And considering that we'll see Korra's female cousin in season 2, there might be some allusion to the arranged marriages in the NWT and whether or not the cousin will be ready for marriage. Or, it might have something to do with why Korra's father is at the South Pole while his brother is the NWT chief.
The White Lotus Society is now a public organization.Look, an army of them took over the Capital City of the Earth Kingdom and saved it from genocide. I think it's fair to assume that they're no longer a secret society.
The spirit world will have a lot of Miyzaki references and inspiration.The creators of the show are fans of Hayao Miyzaki, most notably evidence by Appa being inspired by the Catbus. Many of Miyzaki's works focus on spirits, so it's the perfect opportunity for the creators of the show to throw in a few homages.
A large portion of the Northern Tribe still have issues acknowledging Korra as the AvatarNot only she is from the Southern tribe rather than the Northern one, but she is a female and the North was rather sexist towards females in their society until Katara came along. Assuming those attitudes are kept, Korra will receive a rather poor reception when arriving at the Northern Tribe at some point in Book 2.
Rules for Airbenders in Pro BendingAssuming the Airbenders eventually become populous enough to be able to contribute to the Pro Bending scene, how would one make rules to deal with them? Airbending sports do exist. We've heard of Bison Polo and have seen air scooter races and airball, so Airbending is not incompatible with sports. However, how can one include it in the Pro Bending?
There will be a rise in new refining technologyAnd thus Metalbending will face a new challenge as people develop weapons and tools immune to Metalbending because they have been refined so far the impurities are so small or just not there. And the people who help in this process are Metalbenders.
Tenzin and his family are not the only Airbenders out there.It's unlikely that the Fire Nation killed all the Air Nomads. Some of them probably escaped into other nations, where they got married, had kids, and assimilated into the local culture. Airbender genetics are likely within a few small communities within the Water Tribes or the Earth Kingdom.
The Avatar universe is completely foundamentaly different from oursThe Earth is made of different minerals (it has no iron in the crust, unlike ours which is fairly dense with it) and is in a different shape and position from the Sun. The sun and comets are made of fire and considered ancient firebenders. Basicly everything down the atoms that creat the matter in their universe is different. That is why there are some things that we do not understand when comparing it to our world.
The Avatar world was born from a post-apocalyptic one—likely the result of nuclear war.Follow the destruction of most of civilization, the survivors picked up the pieces (retaining vocal and written language from the old world's two biggest superpowers, America and China respectively) and set to work rebuilding from scratch. Meanwhile, however, the suffering and hate from a planetary-scale nuclear war fueled Vaatu in the spirit world to the point he became powerful enough to break the veil between realms. Subsequently, the spirits looked upon the war as proof the humans have lost their right to dominate the earth, so they began moving in to kick them out. Following the growing establishment of the Spirit Wilds, lion turtles began protecting pockets of humanity on their enormous backs and giving them the power of an element whenever they had to leave for any reason. As the generations went by, humans completely forgot about the old world, even forgetting there are other humans on other lion turtles. And then Wan's story happened, and the rest is history.
The Lion Turtles weren't really hunted to extinction.
The Air Acolytes are a cult
The Air Nomads will be reborn, but the Acolytes will have nothing to do with it.Chong and his hippies, true nomads, have spawned a movement of thousands of people, all wandering across the Earth Kingdom in search of freedom and peace. They've detached themselves from homes and material possesions, and they have pretty good senses of humour. Eventually they'll stumble upon a Lion Turtle, who'll grant them the power of airbending.
The world was much more like our own.The world of mortals originally had no spirits, no lion turtles, no dragons, or any other such creatures. Humans evolved much as they did here on Earth (supported by the fact Vatu taunted Wan by mentioning "crawling out of mud"). Humans grew in knowledge, going through the stone, bronze, and iron ages, building up civilizations, becoming the dominate species on the planet. However, something caused the worlds to collide. The spirits flooded into the world, most through the portals at the portals, others through many other gaps the Avatar world seems to contain. Raava and Vatu also continued their eternal struggle in the mortal realm. Humans could face the threat, how could they fight monsters that aren't fully solid, faster and more agile than the fastest animal, and stronger than ten men, with iron swords and spears? However, some very ancient and powerful beings, the Lion turtles, decided to help humans. They allowed them to build their cities on their backs, gave protection, and the ability to fight back.
The Fog of Lost Souls is much like the Island where Dreams Come True from The Voyage of the Dawn Treader.It seems to play on the fears of its captives, causing them to relive their worst nightmares and/or memories. Kya's worst nightmare somehow involves losing or being abandoned by her family, while Bumi's clearly involves bloodthirsty cannibals. Tenzin is already living a parent's worst nightmare, so the Fog settles for his second worst: Failing the rest of the family and the world.
The physical world and the spirit world are not on different planes, but rather are two separate planets.We see in a lot of the visuals that the Avatar world is just a run of the mill planet like Earth, in a system much like our own (meaning that maybe it exists out there somewhere in the cosmos? But that's another WMG). So what's to say the spirit world isn't the same? It could easily be that the spirit world is simply another planet in another system joined to the Avatar world by a wormhole (or two, depending if you count each pole as a separate wormhole). Because of their having evolved so long in the presence of these wormholes, the people of the Avatar world have a psychic connection with the wormhole, and can project themselves through it and manifest themselves in the spirit world thusly. They can also physically travel there. Spirits, being the native sentient population on the other planet, have the same ability.
Iroh got stuck in the Fog of Lost Souls while searching for his son.It's generally accepted that Iroh's first experience in the spirit world was right after Lu Ten died. And Iroh seems to have some kind of personal experience with the Fog, given the way he warns Tenzin and his siblings about it. Perhaps he, like Tenzin, traveled there intentionally while searching for his kid, was trapped there briefly and was only able to escape after some sort of epiphany.
The reason why there's new Airbenders popping out.Because all the new Airbenders have Air Nomad ancestry, even though Word of God said that all Air Nomads are benders, they didn't say those who are only part.
