Kuvira - everyone must bow...even you

The Legend of Korra — Book 4: Balance — Full Lore

Book Four: Balance is the fourth and final book of The Legend of Korra, consisting of 13 episodes and taking place three years after the events of Book Three: Change. The entire season revolves around the consequences of Zaheer’s attack on Korra, the collapse of the Earth Kingdom, Kuvira’s rise as the Great Uniter, and Korra’s eventual recovery and understanding of what it means to be the Avatar.

The season is ultimately about balance—not simply balance between nations or elements, but balance within people themselves.

⸻

Three years later

Book Three ended with Korra badly traumatized after Zaheer’s attempt to kill her in the Avatar State. Although she survived and the Red Lotus was defeated, Korra was left physically and psychologically devastated.

Three years pass.

During that time, the world changes dramatically.

The Earth Queen is dead, the Earth Kingdom has fractured into numerous independent territories, and there is no effective central government. Different regions are controlled by local leaders, criminals, warlords, and competing factions.

The world leaders initially look toward Suyin Beifong, leader of Zaofu, to help stabilize the Earth Kingdom. Suyin refuses because she does not want to impose Zaofu’s political philosophy on the rest of the country.

Another person, however, is willing to do exactly that.

Kuvira.

Kuvira leaves Zaofu with Suyin’s eldest son, Baatar Jr., and begins traveling throughout the Earth Kingdom. She gathers an increasingly powerful army and offers protection and stability to towns that cannot protect themselves.

Her reputation spreads.

She becomes known as the Great Uniter.

⸻

Kuvira’s rise

Kuvira initially presents herself as a solution to a genuine problem.

The Earth Kingdom is broken.

People are starving. Bandits are attacking settlements. Trade routes have collapsed. Local governments are incapable of protecting their citizens.

Kuvira’s military arrives and restores order.

But there is a condition.

The territories she helps must submit to her authority.

What begins as reunification gradually becomes conquest.

Kuvira’s philosophy is essentially that order and strength must come before individual freedom. She believes the Earth Kingdom became weak because its old political system failed its people.

She therefore intends to create something stronger.

Not simply the old Earth Kingdom.

An Earth Empire.

Her forces include highly trained earthbenders, metalbenders, soldiers, vehicles, trains, and increasingly advanced technology.

She also has Baatar Jr. working alongside her as an engineer and strategist. The two become engaged during the three-year period.

By the beginning of Book Four, Kuvira has brought most of the Earth Kingdom under her control.

⸻

Meanwhile, Korra has disappeared

While Kuvira is building an empire, Korra is nowhere to be found.

She was supposed to return to Republic City and reunite with her friends.

Instead, she has spent approximately six months wandering alone.

Korra doesn’t even identify herself as the Avatar anymore.

She travels through the Earth Kingdom disguised as an ordinary person and eventually participates in underground earthbending matches simply to earn money.

She is physically much better than she was immediately after Zaheer’s attack, but psychologically she remains trapped by what happened.

Korra is haunted by an image of herself in the Avatar State.

This apparition represents much more than a hallucination. It embodies Korra’s trauma, fear, anger, and inability to accept what happened to her.

She repeatedly tries to fight it.

She repeatedly loses.

⸻

Korra Alone

The second episode reveals what happened during the three-year gap.

After Zaheer poisoned her, Korra returned to the Southern Water Tribe.

Katara helped her recover physically.

It took approximately two years for Korra’s body to recover enough for her to walk normally again, but her mind was still struggling.

She continued experiencing visions of Zaheer and the moment he nearly killed her.

Eventually, Korra left home and began traveling around the world, trying to reconnect spiritually with Raava, the spirit of light and balance within the Avatar.

She fails.

Eventually, Korra ends up in the Foggy Swamp.

There she meets someone she never expected to see again.

Toph Beifong.

Toph has been living alone in the swamp for years.

Toph immediately realizes that Korra still has metal poisoning in her body. Tiny amounts of mercury remain embedded within Korra.

But Toph also realizes something deeper:

Korra’s body isn’t the only thing preventing her from recovering.

Part of Korra is subconsciously holding herself back.

She has become afraid of being the Avatar.

If she cannot fully recover, she doesn’t have to face the responsibility again.

Toph helps Korra confront that fear.

Eventually, Korra removes the remaining metal from her body and is finally able to enter the Avatar State again.

⸻

The Earth Kingdom’s new ruler

Back in Republic City, the Earth Kingdom’s royal family prepares for the coronation of Prince Wu.

Wu is the successor to the Earth Kingdom throne.

However, Wu is inexperienced and initially seems more interested in enjoying his position than actually ruling.

Mako has been assigned as his bodyguard.

During the coronation, Kuvira arrives.

Wu honors Kuvira for her efforts to reunify the Earth Kingdom.

But Kuvira reveals that she has no intention of giving the kingdom back.

She declares that the old monarchy is finished.

She will rule instead.

The Earth Kingdom becomes the Earth Empire.

Kuvira has effectively transformed herself from a general who was supposedly restoring the country into its authoritarian leader.

Wu is left powerless.

Kuvira’s justification is that the monarchy allowed the Earth Kingdom to collapse in the first place.

She believes only centralized authority can keep the nation together.

⸻

The Air Nation searches for Korra

Tenzin knows that Korra needs to return.

He sends Jinora, Ikki, and Meelo to find her.

Their search eventually leads them to the Foggy Swamp.

Korra is finally reunited with them.

She is still uncertain about returning to Republic City, but she understands that she cannot keep running forever.

Her friends need her.

The world needs the Avatar.

And Kuvira is becoming increasingly dangerous.

⸻

Kuvira turns toward Zaofu

Kuvira’s next major obstacle is Zaofu.

Zaofu is the metalbending city founded by Suyin Beifong.

It is wealthy, technologically advanced, independent, and refuses to join Kuvira’s Earth Empire.

Kuvira arrives with her enormous army.

She doesn’t immediately attack.

Instead, she gives Suyin an opportunity to surrender.

Suyin refuses.

Korra arrives in Zaofu and attempts to negotiate with Kuvira.

Korra believes she can stop the conflict without fighting.

Kuvira, however, refuses to back down.

She argues that Zaofu cannot remain independent while the rest of the Earth Kingdom has been unified.

⸻

Bolin begins questioning Kuvira

Bolin has joined Kuvira’s army.

At first, he genuinely believes he is helping people.

Kuvira’s army appears organized and heroic compared with the chaos that existed before her rise.

But Bolin gradually discovers what her regime is actually doing.

People who refuse to cooperate are imprisoned.

Dissenters are sent to reeducation camps.

Citizens are forced into labor or military service.

Kuvira’s definition of “unity” increasingly means obedience.

Bolin finally realizes that the cause he joined isn’t what he thought it was.

He decides to escape with Varrick and Zhu Li.

Their escape initially fails, and Bolin is eventually sent to a reeducation camp while Varrick is forced to continue working on Kuvira’s technological projects.

Varrick’s conscience also begins to turn against Kuvira.

⸻

The Battle of Zaofu

Suyin decides that Kuvira must be stopped before Zaofu falls.

She attempts to assassinate Kuvira.

The attempt fails.

Suyin and her sons are captured.

Kuvira then gives Zaofu’s leadership an ultimatum: surrender or face her army.

Korra steps forward.

Kuvira agrees to fight Korra herself.

The two engage in one of the most important fights of the entire series.

Kuvira’s fighting style is incredibly precise.

She uses metal cables and strips of metal as extensions of her movements, attacking rapidly and controlling the battlefield.

Korra initially holds her own.

Eventually, however, Korra enters the Avatar State.

It looks like the fight is over.

But then Korra sees the apparition of herself again.

Her trauma returns.

She freezes.

Kuvira defeats her.

Kuvira is about to finish the fight, but Jinora and Opal intervene, allowing Korra to escape.

This is extremely important to Korra’s character.

She has regained her physical abilities.

But she still hasn’t completely recovered emotionally.

⸻

Korra’s return to Republic City

Korra returns to Republic City.

She reunites with Mako and Asami.

The old Team Avatar dynamic begins returning.

However, Korra is struggling with a new problem:

She doesn’t know whether she is still capable of being the Avatar.

Everyone expects her to stop Kuvira.

But Korra is afraid that she will fail again.

Meanwhile, Prince Wu is kidnapped.

Team Avatar works together to rescue him.

This becomes the first major mission they have undertaken together in three years.

The experience helps Korra reconnect with her friends and realize that she hasn’t lost everything.

⸻

The Spirit Wilds

Kuvira’s expansion eventually reaches Republic City.

The city has already changed significantly because of the events of Book Three.

Spirits now live openly within Republic City.

The Spirit Wilds have become part of the city’s landscape.

But the spirits begin behaving strangely.

People are being captured by the vines.

Korra discovers that Kuvira has been harvesting spirit vines from the Foggy Swamp.

She intends to use their enormous energy potential.

This leads directly to one of Kuvira’s greatest technological achievements.

A weapon powered by spirit energy.

⸻

Korra returns to Zaheer

Korra realizes she needs spiritual help.

She eventually returns to the person who caused the trauma in the first place.

Zaheer.

He is still imprisoned.

Korra confronts him because she believes she cannot fully overcome her fear unless she faces him.

Zaheer initially behaves arrogantly, but he eventually recognizes what Korra is experiencing.

He realizes that his actions have left Korra psychologically trapped.

Zaheer tells her that she has to let go of the fear he created.

Ironically, the man who broke Korra’s confidence becomes part of the process through which she regains it.

With Zaheer’s help, Korra enters the Spirit World and reconnects with Raava.

This is a major turning point.

Korra finally begins to feel whole again.

⸻

Operation Beifong

Meanwhile, Lin Beifong refuses to simply sit back and allow Kuvira to keep Suyin and the rest of the Beifongs imprisoned.

Lin, Opal, and Bolin travel to rescue them.

They eventually find Toph again.

The Beifong family reunion is complicated because of the enormous history between Toph, Lin, and Suyin.

Toph helps them locate the prison facilities.

Eventually, they rescue Suyin and the others.

The family is reunited.

But Kuvira is still preparing for war.

⸻

Kuvira’s ultimate weapon

Varrick has been forced to develop spirit-vine technology for Kuvira.

Eventually, he and Zhu Li realize how dangerous the weapon is.

Kuvira possesses a gigantic cannon capable of firing concentrated spirit energy.

She intends to use it against Republic City.

Her objective is no longer merely to control the Earth Kingdom.

She intends to bring the United Republic of Nations under the Earth Empire as well.

Kuvira believes the territory should belong to her empire and sees Republic City as something that must ultimately submit.

The weapon is eventually incorporated into an enormous mechanized suit.

The result is the Colossus.

A gigantic metal superweapon controlled directly by Kuvira.

⸻

The Colossus

The Colossus is essentially a giant mobile fortress.

It is heavily armored and equipped with Kuvira’s spirit-energy cannon.

Traditional bending attacks are almost useless against it.

The United Forces are unable to stop it.

Republic City prepares for invasion.

The city begins evacuating civilians.

President Raiko prepares the United Forces.

Team Avatar attempts to stop Kuvira before she reaches the city.

They discover the true scale of her weapon.

The Colossus is so powerful that even Team Avatar cannot fight it conventionally.

⸻

Baatar Jr.’s betrayal

Baatar Jr. is still completely devoted to Kuvira.

He believes in her vision and is deeply in love with her.

But Team Avatar eventually captures him.

Korra and Suyin try to convince him to reveal how the Colossus works.

He refuses.

Then Korra threatens him with something emotionally devastating:

If Kuvira continues her attack, he may never see her again.

This finally breaks through his loyalty.

Baatar contacts Kuvira and tells her that he has been captured.

He asks her to stop the invasion.

For a moment, it appears as though Kuvira agrees.

But Kuvira tracks the signal.

She discovers Team Avatar’s location.

Then she fires the weapon.

The facility is destroyed.

Baatar believes Kuvira has killed him.

This is the moment when his devotion to her completely collapses.

⸻

The invasion of Republic City

Kuvira’s army reaches Republic City.

The Colossus towers over the city.

The United Forces attempt to stop it.

They fail.

Team Avatar realizes they cannot destroy it from outside.

They need to get inside.

This leads to the final battle.

⸻

Hiroshi Sato returns

Asami’s father, Hiroshi Sato, has been imprisoned since Book 1.

Because of the desperate situation, he is temporarily released.

Hiroshi reunites with Asami.

Their relationship is complicated because of everything that happened between them.

But Hiroshi wants to help his daughter.

He and Asami work together with Varrick and Zhu Li to create specialized platinum-cutting hummingbird suits.

These machines are designed specifically to cut through the Colossus’s armor.

Hiroshi pilots one himself.

The machines cut into the Colossus.

Hiroshi sacrifices himself so that Asami can reach the opening and enter.

Asami survives.

Hiroshi does not.

This finally gives Asami closure with her father.

⸻

Team Avatar enters the Colossus

Korra, Mako, Bolin, Lin, and Suyin enter the giant machine.

They split into groups.

Korra goes after Kuvira.

Mako and Bolin go after the power source.

Lin and Suyin target the cannon.

Inside the Colossus, the battle becomes chaotic.

The machine is filled with spirit-vine energy.

The closer Team Avatar gets to the core, the more dangerous everything becomes.

⸻

Mako and Bolin

Mako and Bolin reach the spirit-vine core.

Mako realizes that destroying the core will probably require him to use his lightningbending against it.

This could kill him.

Bolin refuses to let his brother sacrifice himself.

They eventually manage to destabilize the core without Mako dying.

The Colossus begins to collapse.

⸻

Lin and Suyin

Lin and Suyin attack the cannon.

They manage to damage the weapon’s loading mechanism.

Kuvira responds by ripping the cannon arm away from the Colossus.

Lin and Suyin are still inside the detached section.

Kuvira throws it into the Spirit Wilds.

They survive.

But the Colossus itself is beginning to fail.

⸻

Korra vs. Kuvira

Inside the cockpit, Korra finally confronts Kuvira.

This time, Korra isn’t fighting from fear.

She isn’t the broken Avatar who fought Kuvira at Zaofu.

She is finally emotionally present.

Korra and Kuvira fight directly.

Their bending styles mirror each other.

Both are powerful, disciplined, and exceptionally determined.

Kuvira is one of the few people capable of fighting Korra at an extremely high level even without relying on overwhelming force.

The fight continues as the Colossus collapses around them.

Eventually, the machine explodes.

Korra and Kuvira are thrown into the Spirit Wilds.

⸻

The final confrontation

Kuvira refuses to surrender.

She finds the detached spirit-energy cannon.

She aims it at Korra.

Kuvira fires.

But the weapon becomes unstable.

She loses control.

Kuvira tries to shut it down, but the energy continues building.

Korra realizes that Kuvira is about to be destroyed by her own weapon.

Instead of attacking her, Korra protects her.

Korra enters the path of the energy and redirects it.

This creates an enormous surge of spirit energy.

The energy tears open a brand-new spirit portal.

Korra and Kuvira are pulled into the Spirit World.

⸻

Korra understands Kuvira

Inside the Spirit World, the battle finally stops.

Korra talks to Kuvira.

And for the first time, Kuvira genuinely opens up.

Kuvira explains her motivations.

She had been abandoned as a child and eventually taken in by the Beifongs.

She grew up believing that strength and control were necessary to protect people.

She genuinely believed she was saving the Earth Kingdom.

Korra recognizes something in her.

Kuvira’s obsession with control resembles Korra’s own struggles.

Both women had tried to solve their problems through strength.

Both feared being powerless.

Both believed that if they could just become strong enough, they could prevent chaos.

Korra realizes that defeating Kuvira physically won’t solve the problem.

She needs to understand her.

Kuvira finally recognizes how far she has gone.

She admits defeat.

She agrees to surrender.

⸻

Kuvira’s surrender

Kuvira returns from the Spirit World.

Her army is still waiting.

Kuvira tells them to stand down.

She is arrested by Lin and Suyin.

The Earth Empire collapses.

The immediate threat is over.

But the political consequences remain.

⸻

Prince Wu changes the monarchy

After everything is over, Prince Wu reveals that he intends to abolish the Earth Kingdom monarchy.

Instead of another hereditary ruler, the people will eventually be allowed to choose their own leaders.

Wu realizes that simply replacing one monarch with another isn’t enough.

The old political structure contributed to the instability that allowed Kuvira to rise.

This represents another major theme of the season:

The world cannot simply return to how it was before.

It has to change.

⸻

Varrick and Zhu Li

Varrick and Zhu Li also receive their happy ending.

Varrick finally realizes that Zhu Li is much more than his assistant.

He proposes to her.

They eventually marry at Air Temple Island, with Bolin acting as the officiant.

Their relationship closes one of the season’s lighter storylines.

⸻

Korra’s final transformation

At the beginning of Book Four, Korra believes that being strong means being able to defeat anything.

By the end, she understands something very different.

She doesn’t need to dominate every opponent.

She doesn’t need to be invulnerable.

She doesn’t need to avoid vulnerability.

Her greatest victory over Kuvira isn’t that she beats her in combat.

It’s that Korra understands her.

Korra’s journey through Book Four is therefore a journey from strength through force to strength through understanding.

⸻

Korra and Asami

The final scene belongs to Korra and Asami.

After everything that happened, Asami tells Korra that she is simply happy that Korra is alive.

The two talk privately.

Asami suggests that they take a vacation together in the Spirit World.

They walk toward the new spirit portal.

They hold hands.

Then they enter the Spirit World together.

The series ends there.

⸻

The overall meaning of Book 4

Book Four is ultimately about recovery, control, trauma, political power, and balance.

Korra’s story

Korra begins the season believing that she has failed.

She is physically recovering but emotionally trapped by her past.

By the finale, she understands that her trauma does not make her weak. She can acknowledge what happened without allowing it to define her.

Kuvira’s story

Kuvira begins as someone trying to save a broken country.

Her desire for order becomes obsession.

Her belief that she alone knows what is best eventually turns her into the very kind of authoritarian ruler she believes she is protecting people from.

The Earth Kingdom

The old Earth Kingdom collapses.

Kuvira attempts to replace it with the Earth Empire.

After her defeat, Prince Wu begins the process of replacing the monarchy with a more democratic system.

The Avatar

Korra’s relationship with her role changes.

She no longer sees being the Avatar simply as a responsibility to fight stronger enemies.

She becomes a mediator, healer, and bridge between people and spirits.

The central idea

Balance doesn’t mean making everything perfectly equal or eliminating conflict.

It means learning how to live with opposing forces without allowing one to consume everything else.

That’s why the final confrontation between Korra and Kuvira is not ultimately won through superior bending.

Korra wins because she finally understands that power alone cannot create balance.

Absolutely — here are separate, detailed character descriptions, focusing specifically on their backstory, personality, abilities, relationships, and role/effect in Book 4. I’m including the major characters and the characters who meaningfully affect the Book 4 storyline.

⸻

KUVIRA

Kuvira is the primary antagonist of Book 4 and one of the most politically and militarily powerful people in the world. She is a highly skilled metalbender, military commander, politician, and eventually the self-proclaimed leader of the Earth Empire.

Kuvira was orphaned as a child and was eventually taken in by Suyin Beifong, becoming part of the Beifong family alongside Suyin’s biological children. Growing up in Zaofu exposed her to metalbending, advanced technology, and Suyin’s philosophy of creating a progressive society. Kuvira became especially talented at metalbending and developed an exceptionally disciplined personality.

As she grew older, Kuvira became a member of Zaofu’s security forces. When the Earth Kingdom collapsed after the death of its queen and the chaos caused by the Red Lotus, Kuvira saw an opportunity to restore stability. She left Zaofu and began gathering an army, initially claiming that she wanted to reunify the fractured Earth Kingdom.

Kuvira’s methods are extremely effective. She protects villages from bandits and provides food, security, transportation, and infrastructure. This earns her genuine support from many ordinary citizens. However, her version of unity requires obedience. Territories that refuse to join her are threatened or conquered, and people who oppose her government can be imprisoned or sent to reeducation camps.

Eventually, Kuvira declares herself the leader of the Earth Empire, rejecting the old Earth Kingdom monarchy and preparing to replace it with her own centralized government.

She is exceptionally confident, calculating, and controlled. Kuvira rarely loses her composure, even under extreme pressure. She believes that hesitation is weakness and that leaders must be willing to make difficult decisions for the greater good.

Her metalbending is one of her defining traits. She uses thin metal strips and cables as extensions of her limbs, allowing her to attack, restrain, disarm, and redirect opponents with incredible precision. Her fighting style is fast, efficient, and almost mechanical.

Her relationship with Suyin becomes one of the most important personal conflicts in Book 4. Suyin once treated Kuvira like family, but Kuvira ultimately sees Suyin’s refusal to submit as betrayal.

Her relationship with Baatar Jr. is romantic and political at the same time. He becomes her fiancé and chief engineer, helping develop the technology that allows her to build the Colossus.

Kuvira’s greatest flaw is that she becomes convinced that her judgment is superior to everyone else’s. She begins with the belief that she is saving the Earth Kingdom, but gradually becomes willing to sacrifice individual people for her vision of unity.

Her eventual confrontation with Korra becomes deeply symbolic because both women have struggled with control, strength, fear, and vulnerability. Korra ultimately defeats Kuvira not simply by overpowering her, but by understanding her.

⸻

KORRA

Korra is the Avatar and protagonist of the entire series. By Book 4, she is eighteen years old and has already experienced more than almost any previous Avatar shown in the series.

Born in the Southern Water Tribe, Korra was identified as the Avatar when she was very young. Unlike Aang, who spent much of his childhood avoiding his responsibilities, Korra wanted to become the Avatar and was eager to learn bending.

She mastered water, earth, and fire at a young age before traveling to Republic City to learn airbending from Tenzin.

Over the course of the series, Korra fought Amon, Unalaq and Vaatu, Zaheer, and the Red Lotus. Every conflict changed her.

By the end of Book 3, Zaheer’s attack leaves Korra severely traumatized. He poisons her with mercury and forces her into the Avatar State. Although she survives, the experience permanently affects her psychologically.

Book 4 begins three years later.

Physically, Korra has largely recovered.

Mentally, she has not.

She is haunted by visions of her younger self in the Avatar State. She struggles with fear, guilt, anger, and the belief that she has failed as the Avatar.

Instead of returning to Republic City, she wanders the Earth Kingdom disguised as an ordinary person. Eventually, she meets Toph, who discovers that remnants of metal are still inside Korra’s body.

Toph helps Korra understand that her physical injury isn’t the only thing holding her back. Korra is subconsciously resisting her own recovery because accepting her role as Avatar means confronting what happened to her.

Throughout Book 4, Korra gradually regains confidence.

Her relationship with Kuvira becomes the central conflict of the season. At first, Korra attempts diplomacy because she wants to prevent another war. After being defeated by Kuvira at Zaofu, however, she realizes she cannot simply avoid confrontation.

Her eventual battle with Zaheer helps her confront the source of her trauma.

By the finale, Korra has fundamentally changed. She no longer believes that strength means defeating everyone who opposes her.

Her final victory over Kuvira comes through empathy and understanding.

⸻

ASAMI SATO

Asami Sato is one of Korra’s closest friends and one of the most important non-benders in the series.

She is the daughter of Hiroshi Sato, the founder of Future Industries. Asami grew up wealthy and received an excellent education, becoming highly skilled in engineering, technology, business, driving, and martial arts.

Her life changed when she discovered that her father was secretly supporting the Equalists.

Although Hiroshi became an enemy during Book 1, Asami rejected his ideology and chose to stand with Korra.

Afterward, Asami became the head of Future Industries.

By Book 4, she is an experienced businesswoman and engineer rather than simply the wealthy girl she was at the beginning of the series.

She is intelligent, calm, practical, and extremely loyal.

Her friendship with Korra becomes increasingly important during Book 4. While Korra is recovering from her trauma, Asami remains one of the people she trusts most.

Asami also has a complicated relationship with her father. Hiroshi has been imprisoned for years because of his crimes, but the invasion of Republic City eventually creates an opportunity for them to reunite.

Hiroshi helps Asami during the final battle by developing technology capable of cutting through the Colossus.

His sacrifice deeply affects Asami.

By the end of the series, Asami and Korra’s relationship becomes romantic. They decide to travel together into the Spirit World, ending the series with the two of them entering the new spirit portal together.

⸻

MAKO

Mako is an accomplished firebender and one of Korra’s closest friends.

He grew up in Republic City with his younger brother, Bolin. Their parents died when they were young, forcing Mako to become responsible for both himself and his brother.

The brothers eventually joined the pro-bending circuit and became members of the Fire Ferrets.

Mako is serious, responsible, protective, and often more cautious than Bolin.

He previously dated both Korra and Asami, creating a complicated love triangle during the earlier books. By Book 4, however, the romantic complications have largely faded and Mako’s relationships with both women have become friendships.

Mako spends much of Book 4 serving as Prince Wu’s bodyguard.

This forces him into an unusual role because Wu is inexperienced and often immature.

Mako gradually becomes one of Wu’s most reliable protectors.

During the final battle against Kuvira, Mako and Bolin work together inside the Colossus. Mako risks his life while trying to destroy the spirit-vine power source.

His willingness to sacrifice himself for his brother demonstrates how much he has matured since the beginning of the series.

⸻

BOLIN

Bolin is Mako’s younger brother and one of the most cheerful characters in the series.

He is an earthbender and eventually discovers that he can also lavabend.

Unlike Mako, Bolin is naturally optimistic, emotional, social, and eager to make friends.

He began his career as a professional pro-bender and later became a member of Team Avatar.

Bolin’s loyalty and desire to be useful sometimes make him vulnerable to manipulation.

This becomes extremely important in Book 4.

When Kuvira begins building her Earth Empire, Bolin joins her army.

At first, he genuinely believes that Kuvira is helping people. He sees villages becoming safer and believes that he is participating in something heroic.

Eventually, however, he discovers the darker side of Kuvira’s regime.

He realizes that people who resist her are imprisoned and that Kuvira’s “unity” is not voluntary.

Bolin attempts to leave.

He ends up imprisoned alongside Varrick.

Eventually, he escapes and helps Team Avatar fight against Kuvira.

His storyline demonstrates how Kuvira’s propaganda works: she doesn’t necessarily recruit evil people. She recruits people who genuinely believe they’re doing something good.

⸻

TOPH BEIFONG

Toph is one of the most important characters from the original Avatar: The Last Airbender and returns in Book 4 as a major influence on Korra.

Toph was born into the wealthy Beifong family and became the world’s greatest earthbending prodigy. Despite being blind, she learned to sense vibrations through the earth and developed seismic sense.

She eventually invented metalbending.

As an adult, Toph founded the Metalbending Police Force in Republic City and became its first chief.

However, she eventually left civilization and began living alone in the Foggy Swamp.

By Book 4, Toph is elderly and much more relaxed than she was when she was younger.

She meets Korra in the swamp and immediately recognizes that Korra is still carrying metal inside her body.

Toph removes the remaining metal and helps Korra understand the psychological component of her recovery.

Toph is brutally honest with Korra.

She refuses to treat her like a fragile person.

Instead, she forces Korra to acknowledge her own fear.

Toph’s role in Book 4 is therefore much more than simply helping Korra remove metal. She becomes one of the people who helps Korra finally accept herself again.

⸻

SUYIN BEIFONG

Suyin Beifong is Toph’s younger daughter and Lin Beifong’s half-sister.

Unlike Lin, Suyin rejected the traditional police-oriented path of the Beifong family.

She eventually founded Zaofu, a technologically advanced metalbending city that became famous for its art, architecture, metalbending, and progressive society.

Suyin is confident, independent, creative, and politically idealistic.

She also has a complicated history with Kuvira.

Suyin took Kuvira in when Kuvira was young and treated her as part of the family.

Kuvira eventually became part of Zaofu’s security forces.

When Kuvira begins trying to reunify the Earth Kingdom, Suyin initially supports her.

But when Kuvira attempts to make Zaofu part of the Earth Empire, Suyin refuses.

Their relationship becomes extremely bitter.

Kuvira sees Suyin’s refusal as betrayal.

Suyin sees Kuvira as someone who has abandoned the values she was raised with.

Suyin eventually attempts to assassinate Kuvira, fails, and is captured.

She later escapes and joins the fight against the Colossus.

⸻

LIN BEIFONG

Lin is Toph’s older daughter and Suyin’s half-sister.

She inherited her mother’s exceptional earthbending and metalbending abilities and became Chief of Police in Republic City.

Lin initially has a strained relationship with Suyin because of Suyin’s past and their very different personalities.

By Book 4, however, the two sisters have become much closer.

Lin is intensely loyal to Republic City and extremely protective of her family.

She becomes directly involved in rescuing Suyin from Kuvira and later fights alongside her during the final battle.

Lin’s relationship with Toph is also important.

Toph’s absence and complicated parenting affected both Lin and Suyin differently.

Book 4 gives Lin an opportunity to work alongside her mother and sister, bringing the Beifong family together during the crisis.

⸻

BAATAR JR.

Baatar Jr. is Suyin’s eldest son and an extremely talented engineer.

He grew up in Zaofu surrounded by metalbending and technology.

Unlike some of his siblings, Baatar Jr. is highly serious and intensely focused on engineering.

He becomes romantically involved with Kuvira.

When Kuvira leaves Zaofu to unify the Earth Kingdom, Baatar Jr. follows her.

He becomes one of the most important engineers in the Earth Empire and helps develop its advanced military technology.

Eventually, he helps create the Colossus.

Baatar Jr.’s loyalty to Kuvira becomes so strong that he is willing to betray his own family.

However, when Kuvira ultimately attempts to kill him after discovering that he has been captured by Team Avatar, his devotion collapses.

He realizes that Kuvira values her empire more than she values him.

His character demonstrates how Kuvira’s authoritarianism eventually destroys even her closest relationships.

⸻

VARRICK

Varrick is an eccentric businessman, inventor, and former criminal from the Southern Water Tribe.

He is extremely wealthy, charismatic, unpredictable, and intelligent.

Varrick initially appears as a comic-relief character but becomes increasingly important to the larger political story.

By Book 4, he has become involved with Kuvira because of her demand for advanced technology.

Kuvira forces him to develop weapons based on spirit-vine energy.

Varrick eventually realizes how dangerous her plans are.

His conscience grows stronger when he sees that the technology he is creating could cause enormous destruction.

He eventually works with Zhu Li to sabotage Kuvira’s plans.

Varrick’s storyline demonstrates that even someone who has previously behaved selfishly can recognize when something has gone too far.

⸻

ZHU LI

Zhu Li is Varrick’s incredibly capable assistant.

For much of the series, she appears to simply follow Varrick’s instructions.

However, Book 4 reveals just how intelligent and independent she really is.

Zhu Li has spent years working alongside Varrick and understands his inventions better than almost anyone.

When Kuvira forces them to work on the spirit-vine weapon, Zhu Li secretly begins helping Varrick undermine Kuvira.

She eventually becomes an active participant in the resistance against Kuvira.

Her relationship with Varrick also develops romantically.

Their eventual marriage is one of the happiest moments at the end of the series.

⸻

TENZIN

Tenzin is Aang and Katara’s youngest child and the master responsible for rebuilding the Air Nation.

He is an airbending master and the spiritual leader of the new generation of Air Nomads.

Tenzin spent much of his life carrying the enormous responsibility of being Aang’s only airbending child.

By Book 4, he has become a much more confident leader.

Korra’s disappearance worries him deeply.

He sends Jinora, Ikki, and Meelo to search for her.

Tenzin understands that Korra is more than simply a political weapon against Kuvira. She is a person who has suffered and needs time to recover.

His role throughout Book 4 is primarily supportive, as the new Air Nation helps protect the world while Korra deals with Kuvira.

⸻

JINORA

Jinora is Tenzin’s eldest daughter and one of the most spiritually gifted airbenders of her generation.

She became a fully realized airbending master and eventually received her tattoos.

She is intelligent, calm, compassionate, and spiritually powerful.

In Book 4, Jinora helps search for Korra and later participates in the fight against Kuvira.

She and the other Air Nomads rescue Korra when Kuvira defeats her at Zaofu.

Jinora represents the continuation of the Air Nomad tradition that began with Aang.

⸻

IKki AND MEELO

Ikki and Meelo are Tenzin’s younger children.

Ikki is energetic, curious, talkative, and adventurous.

Meelo is chaotic, confident, and often hilariously inappropriate.

Despite their comedic personalities, both are capable airbenders and important members of the new Air Nation.

They participate in the search for Korra and help defend the world from Kuvira.

Their presence also emphasizes how much the Air Nation has grown since Book 1.

⸻

KATARA

Katara is one of the original members of Team Avatar from Avatar: The Last Airbender and one of the world’s greatest waterbenders.

She married Aang and became the mother of Bumi, Kya, and Tenzin.

By Korra’s lifetime, Katara is elderly but remains an extremely respected healer and master.

After Zaheer’s attack, Korra returns to the Southern Water Tribe and spends a long period recovering under Katara’s care.

Katara helps Korra physically recover from her injuries.

Although she does not have a huge amount of screen time in Book 4, her role is important because she represents the support system that kept Korra alive and helped her recover after Zaheer’s attack.

⸻

ZAHEER

Zaheer is the primary antagonist of Book 3 and one of the most psychologically important characters in Book 4.

He was originally an anarchist revolutionary and leader of the Red Lotus.

After gaining airbending, he became one of the most dangerous enemies Korra ever faced.

In Book 3, Zaheer poisoned Korra with mercury and forced her into the Avatar State while attempting to kill her.

He was eventually defeated and imprisoned.

Three years later, Korra remains traumatized by what he did.

Although Zaheer is still imprisoned, Korra eventually seeks him out.

She realizes that she cannot completely move forward while remaining terrified of him.

Zaheer ultimately helps Korra enter the Spirit World and let go of the psychological grip he has over her.

This creates one of the strangest relationships in the series: Korra receives help recovering from the very person who caused her trauma.

⸻

PRINCE WU

Prince Wu is the heir to the Earth Kingdom monarchy.

He is the nephew of Earth King Kuei and becomes the successor after the Earth Kingdom’s collapse.

At first, Wu appears immature, spoiled, and primarily interested in having fun.

Mako is assigned to protect him.

However, Wu gradually becomes more serious as he realizes the responsibility he is about to inherit.

Kuvira rejects Wu’s claim to the throne and instead establishes the Earth Empire.

After Kuvira’s defeat, Wu chooses not to restore the old monarchy.

Instead, he begins planning a transition toward democratic elections.

His character represents the possibility of a new political future for the Earth Kingdom.

⸻

HIROSHI SATO

Hiroshi Sato is Asami’s father and the founder of Future Industries.

He was originally one of Republic City’s wealthiest and most influential businessmen.

After becoming convinced that non-benders were oppressed by benders, Hiroshi secretly supported Amon and the Equalists.

Asami rejected her father’s ideology.

Hiroshi was eventually imprisoned.

In Book 4, the approaching war forces Republic City to temporarily release him.

Hiroshi reunites with Asami and uses his engineering skills to help build the technology necessary to penetrate the Colossus.

He ultimately sacrifices himself so that Asami can enter the machine.

His final actions allow him to make amends with his daughter and demonstrate that, despite his past crimes, he still loves her.

⸻

RAAVA

Raava is the ancient spirit of light and order who exists within the Avatar.

She has been connected to the Avatar cycle since the beginning of human history.

During Book 2, Korra’s connection with Raava is nearly destroyed when Vaatu is separated from her.

Korra eventually reconnects with Raava.

By Book 4, Raava represents an important part of Korra’s identity.

Korra’s inability to reconnect with her after Zaheer’s attack is symbolic of how disconnected Korra has become from herself.

When Korra finally enters the Spirit World and reconnects with Raava, it represents her emotional recovery as much as her spiritual recovery.

⸻

TARRLOK

Although Tarrlok is no longer alive during Book 4, his legacy affects Korra.

Tarrlok was a former member of the United Republic Council and the younger brother of Amon, whose real name was Noatak.

Tarrlok and Amon’s history was revealed during Book 1.

Tarrlok eventually sacrificed himself to stop his brother.

His story is part of the larger history of political conflict that shaped Korra’s early years as Avatar.

⸻

TONRAQ

Tonraq is Korra’s father and the chief of the Southern Water Tribe.

He is a powerful waterbender and a protective father.

After Zaheer’s attack, Tonraq supports Korra throughout her recovery.

He wants to protect her but ultimately has to allow her to make her own decisions.

By Book 4, Korra’s relationship with him has become more mature.

⸻

KYA

Kya is Katara and Aang’s daughter and Tenzin’s older sister.

She is an accomplished waterbender and healer.

Kya is one of the people who helps support Korra during her recovery.

She also represents the continuation of Katara’s waterbending legacy.

Although she is not central to Kuvira’s storyline, her presence contributes to Korra’s wider support network.

⸻

ZAOFU’S BEIFONG FAMILY

The Beifong family is particularly important to Book 4 because Kuvira was once part of them.

The family includes:

• Toph, the original founder of metalbending.

• Lin, the older daughter and former police chief.

• Suyin, the younger daughter and founder of Zaofu.

• Baatar Jr., Suyin’s eldest son and Kuvira’s fiancé.

• Opal, Suyin’s daughter and an airbender.

• Huan, the artistic son.

• Wei and Wing, the twin metalbending sons.

• Baatar Sr., Suyin’s husband and architect of Zaofu.

Their complicated relationships with Kuvira make the Zaofu storyline deeply personal.

Kuvira isn’t simply invading a random city.

She is confronting the family that raised her.

⸻

OPAL

Opal is Suyin’s daughter and one of the first members of the new generation of Air Nomads.

She becomes an airbender after Harmonic Convergence.

Opal is compassionate but also determined.

She becomes especially important when Kuvira attacks Zaofu because she refuses to abandon her family.

She eventually joins the resistance against Kuvira.

Her relationship with Baatar Jr. becomes strained because he chooses Kuvira over his family.

⸻

ZHU LI, VARRICK, AND THE EARTH EMPIRE

Together, Varrick and Zhu Li demonstrate another important side of Kuvira’s regime.

Kuvira doesn’t build her empire through bending alone.

She combines:

military power + industrial technology + propaganda + transportation + spirit energy + political control.

This is what makes her more dangerous than previous villains.

Amon had an army.

Unalaq had spiritual power.

Zaheer had ideology and the Red Lotus.

Kuvira combines politics, military organization, technology, and bending.

That combination is what allows her to become the central threat of Book 4.

Additional Book 4 Characters

Baatar Sr.

Baatar Sr. is Suyin Beifong’s husband and the father of Baatar Jr., Opal, Huan, Wei, and Wing. He is an architect and one of the people responsible for the development of Zaofu’s distinctive futuristic design.

Unlike his son Baatar Jr., Baatar Sr. remains loyal to Suyin and Zaofu when Kuvira demands that the city surrender.

His importance in Book 4 comes primarily through his family. Kuvira’s rise creates a conflict between the family he helped build and the woman he once considered part of that family.

He is captured when Kuvira takes Zaofu but later escapes with the rest of the Beifongs.

⸻

HUAN BEIFONG

Huan is Suyin’s second-oldest son and one of Zaofu’s more eccentric members.

Unlike his relatives, Huan is primarily interested in art rather than combat or politics. He uses metalbending creatively to create sculptures and other artwork.

His personality is artistic, philosophical, and somewhat detached from the political conflict surrounding Zaofu.

However, when Kuvira attacks, Huan is forced to confront the fact that his family’s peaceful lifestyle cannot remain isolated from the rest of the world.

His character helps show what Zaofu represents: a society built around creativity, innovation, and individual expression rather than military control.

⸻

WEI AND WING BEIFONG

Wei and Wing are Suyin’s twin sons.

Both are talented metalbenders and members of Zaofu’s metalbending culture.

They are playful and competitive with each other, often turning situations into contests.

Their importance in Book 4 comes from their connection to the Beifong family and Zaofu’s defense.

Like the rest of the family, they are caught in Kuvira’s takeover of Zaofu.

Their metalbending abilities also demonstrate how advanced Zaofu’s metalbending tradition has become generations after Toph invented the art.

⸻

GHAZAN

Ghazaan is not alive during Book 4, but his legacy is important to Bolin.

He was a member of the Red Lotus and an extremely powerful lavabender.

During Book 3, Ghazan taught Bolin that lava is not simply something to fear and that earthbending can be approached differently.

Bolin’s ability to lavabend becomes an important part of his identity.

This matters in Book 4 because Bolin is much more confident in his abilities when he fights alongside Team Avatar.

Ghazaan therefore indirectly influences Bolin’s development even after his death.

⸻

MING-HUA

Ming-Hua was another member of the Red Lotus and an exceptionally talented waterbender.

She had no arms and used waterbending to create temporary water limbs.

She was eventually defeated during the climax of Book 3.

Like Ghazan, her importance in Book 4 is primarily through the trauma left behind by the Red Lotus.

Korra’s struggle with what happened in Book 3 remains the central psychological conflict of Book 4.

⸻

P’LI

P’Li was Zaheer’s partner and the combustionbender of the Red Lotus.

She possessed an extremely rare ability that allowed her to generate explosive energy from her forehead.

She was killed during the battle with the Beifongs in Book 3.

Her death, along with the deaths of Ghazan and Ming-Hua, helped make Zaheer’s defeat possible.

But for Korra, the entire experience remains deeply traumatic.

⸻

KAI

Kai is one of the younger members of the new Air Nation.

Originally a street thief, Kai was recruited by Tenzin and eventually became an airbender.

By Book 4, Kai has matured considerably.

He is more responsible and committed to the Air Nation than he was when he first appeared.

He participates in missions involving the search for Korra and the protection of the world from Kuvira.

Kai represents how the new Air Nation is made up of people from many different backgrounds rather than simply descendants of the original Air Nomads.

⸻

ZAHEER’S RED LOTUS LEGACY

Although the Red Lotus members are mostly absent from Book 4, their actions are responsible for much of the season’s political situation.

The death of the Earth Queen created a power vacuum.

Zaheer’s attack on Korra left the Avatar psychologically damaged.

The collapse of the Earth Kingdom allowed Kuvira to present herself as the person capable of restoring order.

This creates an important connection between the two antagonists.

Zaheer destroys the old order. Kuvira rises from the destruction.

They have completely different philosophies.

Zaheer believes all forms of centralized authority should be destroyed.

Kuvira believes centralized authority is necessary for stability.

Yet both fundamentally challenge Korra’s understanding of balance.

⸻

PRESIDENT RAiko

Raiko is the President of the United Republic.

He became the first elected president after the political reforms that followed the Equalist crisis.

By Book 4, Raiko is much more experienced than he was earlier in the series.

He has to deal with the threat of Kuvira while also protecting Republic City’s independence.

Raiko initially attempts diplomacy.

He understands that directly attacking Kuvira could trigger an enormous war.

However, when Kuvira begins preparing to invade Republic City, Raiko mobilizes the United Forces.

He represents the political side of the conflict, while Korra represents the Avatar’s responsibility to maintain balance.

⸻

GENERAL IROH

General Iroh is a high-ranking commander of the United Forces and a descendant of the original Fire Nation royal family.

He is named after the legendary Uncle Iroh.

He previously fought alongside Korra during the Equalist conflict and remains one of the United Republic’s strongest military leaders.

In Book 4, Iroh participates in the defense of Republic City against Kuvira.

His presence demonstrates that the nations are willing to cooperate against the Earth Empire.

The United Forces represent the modern world’s attempt to respond collectively to Kuvira’s aggression.

⸻

PRINCESS IZUMI

Izumi is the Fire Lord during Book 4 and the daughter of Zuko.

She is calm, thoughtful, and cautious.

Unlike some previous Fire Nation rulers, Izumi does not want to casually send the Fire Nation into another war.

When Kuvira threatens Republic City, the Fire Nation is asked to participate in the conflict.

Izumi initially refuses to launch an offensive because she understands the catastrophic consequences another world war could create.

This is an important contrast with Kuvira.

Kuvira sees military strength as the solution to political problems.

Izumi sees military power as something that must be used carefully.

⸻

ZUKO

Zuko is now an elderly former Fire Lord and one of the most respected leaders in the world.

After the events of Avatar: The Last Airbender, Zuko spent decades helping transform the Fire Nation and maintain peace between the nations.

By Book 4, he has stepped away from direct political leadership.

However, his decisions continue to influence the modern world.

He participates in discussions concerning Kuvira and the Earth Empire.

Zuko represents the older generation of leaders who helped create the relatively peaceful world that Kuvira threatens to destroy.

⸻

TYLEE

Ty Lee was one of Azula’s former allies during the Hundred Year War.

After the war, she became a Kyoshi Warrior.

Although she has little direct involvement in Book 4, the Kyoshi Warriors themselves remain part of the broader world established by the original series.

Her transformation from an imperial warrior into a protector is another example of how the world changed after the Hundred Year War.

⸻

MAI

Mai was formerly one of Azula’s closest allies and later became Zuko’s girlfriend.

She is not a major participant in Book 4, but her relationship with Zuko is part of the history of the Fire Nation’s post-war generation.

⸻

KING BUMI

Bumi is Aang and Katara’s eldest child.

Unlike his siblings, he was originally a nonbender.

After Harmonic Convergence, Bumi became an airbender.

By Book 4, he is an experienced member of the new Air Nation.

His military background and unconventional personality make him useful during the various crises surrounding Korra.

He is another example of how Harmonic Convergence dramatically changed the world.

⸻

KYA

Kya is Aang and Katara’s second child and Tenzin’s older sister.

She is a waterbending master and healer.

Kya has a somewhat complicated relationship with Tenzin because their father’s focus on rebuilding the Air Nation often left Kya and Bumi feeling overlooked.

By Book 4, however, the siblings have become much closer.

Kya helps support the Air Nation and Korra during the crisis involving Kuvira.

⸻

ZAHEER AND KORRA’S PSYCHOLOGICAL CONNECTION

Zaheer deserves special attention because his influence on Book 4 is almost entirely psychological.

Kuvira is the physical and political antagonist.

Zaheer is the ghost of Korra’s past.

Korra’s biggest obstacle throughout the season isn’t simply Kuvira’s army.

It’s the belief that Zaheer permanently broke her.

Her hallucination of herself represents everything she fears:

• The Avatar she used to be

• Her inability to control herself

• Her fear of the Avatar State

• The pain she experienced

• Her fear of being defeated again

• Her belief that she has become weaker

When Korra finally meets Zaheer again, she isn’t looking for forgiveness.

She wants to stop being afraid of him.

That encounter allows her to reclaim control over her own identity.

⸻

RAAVA AND THE AVATAR CYCLE

Raava’s importance to Book 4 is subtle but enormous.

The Avatar is not simply a person with four bending elements.

The Avatar exists because Raava and the human spirit of Wan became permanently connected.

Every Avatar inherits the experiences and knowledge of previous Avatars.

Korra’s connection to that cycle was severely disrupted during Book 2 when Unalaq and Vaatu separated her from Raava.

Korra eventually restored the connection.

After Zaheer’s attack, however, Korra feels spiritually disconnected again.

Her recovery in Book 4 therefore isn’t only physical.

She must reconnect with the spiritual side of herself.

When she finally enters the Spirit World and reconnects with Raava, she becomes capable of entering the Avatar State without being consumed by fear.

⸻

KUVIRA AND SUYIN

This is one of the most important relationships in Book 4.

Suyin didn’t simply know Kuvira.

She raised her.

Kuvira was taken in by Suyin after being orphaned.

Suyin gave her a home, taught her metalbending, and gave her a place within Zaofu.

Kuvira eventually became part of Zaofu’s security forces.

But Suyin’s philosophy was based on individual freedom and creativity.

Kuvira’s philosophy evolved toward centralized authority.

Eventually, Kuvira leaves Zaofu and begins creating the Earth Empire.

When she returns years later demanding that Zaofu submit, Suyin sees it as a betrayal of everything she taught Kuvira.

Kuvira sees Suyin’s refusal as hypocrisy and weakness.

Their confrontation becomes personal because both women believe they are protecting the Earth Kingdom in their own way.

⸻

KUVIRA AND BAATAR JR.

Baatar Jr. is the person closest to Kuvira emotionally.

He isn’t simply her engineer.

He is her fiancé.

He believes deeply in her vision and chooses her over his own family.

Together, they represent the technological and political machinery of the Earth Empire.

Baatar Jr. helps develop the Colossus because he believes their empire needs overwhelming power to guarantee its survival.

However, Kuvira’s willingness to sacrifice him becomes the breaking point.

When she attempts to kill him after he is captured, Baatar Jr. realizes that her love for him is secondary to her obsession with control.

His betrayal of Kuvira’s plans is one of the things that helps Team Avatar ultimately defeat her.

⸻

KUVIRA AND KORRA

Kuvira and Korra are deliberately written as parallels.

Both are powerful women.

Both are exceptionally talented fighters.

Both have strong personalities.

Both believe in taking action rather than waiting for someone else to solve a problem.

Both have struggled with fear and control.

But their responses are different.

Korra learns that control cannot be forced.

Kuvira becomes obsessed with controlling everything.

Korra eventually accepts vulnerability.

Kuvira sees vulnerability as weakness.

Korra learns to understand her enemies.

Kuvira increasingly views opposition as something that must be eliminated.

That is why their final confrontation is more than a simple hero-versus-villain fight.

It is essentially two different answers to the question of what strength means.

And Korra ultimately proves that understanding can accomplish something force cannot.

⸻

BOOK 4’S MAIN CHARACTER DYNAMIC

At the center of the season are essentially four groups:

Korra and Team Avatar

Trying to protect the world while Korra recovers from her trauma.

Kuvira and the Earth Empire

Trying to create a unified, powerful state through military authority.

The Beifong family

Trying to stop the person they once considered family.

The world’s political leaders

Trying to prevent another global war.

All four collide during the final invasion of Republic City.

And the result changes the political and spiritual structure of the entire world.

The Earth Kingdom’s monarchy begins disappearing.

The Earth Empire collapses.

The new Air Nation becomes a major international force.

Republic City survives.

The Spirit World becomes even more connected to the human world.

And Korra finally becomes comfortable with who she is.

That is what makes Book 4: Balance the conclusion not only of Kuvira’s story, but of Korra’s entire journey as the Avatar.
