Book Three: Fire Edit
At the start of the summer of 100 ASC, Aang learned he had been unconscious for a few weeks after having been shot with lightning. Katara informed Aang that he had grown a head of hair and remarked her admiration of this aspect. Hakoda approached to formally introduce himself to Aang. Katara became angered at his remark of being Sokka and Katara's father seeing as she had just called him "dad". After she demanded privacy from her father, Aang asked if she was angry at him, a statement she denied. Aang, still feeling pain from his injuries, went back to his room with Katara to undergo healing. During the healing session, Aang recalled the battle in Ba Sing Se and realized that he was "gone" before Katara brought him back. The next day, Sokka informed Aang about their return to Chameleon Bay after he was injured. The gang found her father and later captured a Fire Nation ship. Hakoda told Aang that despite the Fire Nation's capture of Ba Sing Se, they still planned to invade the Fire Nation on the Day of Black Sun. In an angered tone, Katara corrected him, stating it was Sokka's plan, surprising her father with this remark. Sokka revealed to Aang that the eclipse was not even their biggest advantage and that they had a secret, being Aang. He explained how the whole world thinks the Avatar is dead which upset Aang.
Katara and the others ran into another Fire Nation ship. The ship captain interrogated Bato and Hakoda, disguised as Fire Nation soldiers, but soon figured out their ship had been captured and arranged plans to sink it. Toph overheard the plans and metalbent the ship to a point that caused the other soldiers to fall off. Katara nearly capsized the enemy ship through the use of waterbending and the team attempted to escape. Despite the tremendous efforts of Katara and Toph, the ship took heavy damage from the pursuing Fire Nation ship. Out of sheer misfortune, the serpent of the Serpent's Pass appeared only to be struck by a stray fireball. The heroes escaped as the enraged serpent attacks the enemy Fire Nation ship. Later on, Katara, Toph and Sokka walked into Aang's room, stating they were going to a market to get dinner. Sokka encouraged Aang to wear a headband to obscure his arrow tattoos, but Aang refused. While Toph and Sokka go to the market, Katara stayed behind to talk with Aang, attempting to console him after he stated his feelings of failure. Shortly after she left, Aang, feeling helpless and useless during the fight and guilty about failing in Ba Sing Se, flew off alone on a mission to regain his honor. Katara, after discovering that Aang was missing, broke down in horror and confronted her father on her feelings about him leaving her and Sokka to fight in the War. She was the first to hug Aang when they found him on the shores of the Fire Nation and was greatly relieved upon seeing he is safe.
Into the Fire Nation Edit
Katara and the others traveled to the Fire Nation with Aang, using airbending and waterbending to hide themselves and Appa in a cloud cover. They took temporary shelter in a cave and decided to seek out new clothes to help them better blend into the Fire Nation. They found an unattended clothesline, stole some outfits and went to town to buy some accessories. Katara sadly removed her mother's Water Tribe necklace to replace it with a Fire Nation one after it was pointed out to be too obviously Water Tribe by Aang.
Aang enrolled in a Fire Nation school and got into trouble for "roughing up" a favored student of the Headmaster, resulting in a parent-teacher conference. Sokka and Katara attended the conference acting as Aang's parents, calling themselves "Mr. Wang Fire" and "Mrs. Sapphire Fire". After the conference, Aang insisted on helping the children in the school and decided to hold a secret dance party for them in the cave. When Aang asked Katara to dance, she began making multiple excuses out of shyness; at last she accepted his offer and took Aang's hand. She became embarrassed by the amount of attention they received from other students, however, Aang smoothly reassured her, leaving her blushing before they became serious. They performed a combination of neijia drills and capoeira in synchronization, which appeared to be an acrobatic dance. However, the headmaster and several teachers appeared on the scene, having been told of the dance by Hide. The crew managed to slip away in the opening behind the cave. While the party flew off on Appa, Toph complimented Aang on his efforts, which she believed had a serious impact on the students. Katara agreed and kissed Aang on the cheek which caused him to blush.
Helping Jang Hui Edit
The group floated downstream in the middle of a river heavily polluted by brown sludge deposited by a nearby military factory. With little chance of catching any food, they decided to buy some at a nearby village floating in the middle of the river. Many villagers were sick because of lack of food or medicine and the polluted water. Katara wished to help the people, but Sokka said their overall mission should remain their primary focus. Katara berated him for his thoughtlessness toward the poor people, but was soon convinced their mission must be given prime importance. When a small child asked her for spare food, however, Katara gave him one of the fish they had bought.
In the morning, Appa was found lying on his side, his tongue purple. Katara suggested the village might have herbs with which to heal him. When they arrived at the village, everyone appeared to be in much better spirits. According to Xu, a legendary local river spirit known as the Painted Lady came and delivered food the previous night. When he stated that no medicine was available, Katara suggested they let Appa rest for another day. That night, a thick mist descended upon the village and the Painted Lady arrived to heal several of the sick. The child Katara helped earlier thanked her and the Painted Lady, actually Katara in disguise, left across the water.
With Appa still sick the next day, they returned to the village. The village, in even higher spirits, had erected a large statue of the Painted Lady in gratitude for healing their sick. Dock suggested that perhaps the Painted Lady could heal Appa. Sokka skeptically noted that the Painted Lady's work would be all for nothing unless she continually helped them for as long as the factory should stand. He jokingly suggested that the spirit should use her "spirit magic" to destroy the building.
That night, Katara once again disguised herself, accidentally waking both Momo and Aang upon her departure. Seeing the Painted Lady, Aang attempted to persuade her to aid their group, prompting Katara to flee. Aang chased her to the village where he discovered her scheme. Appa's illness was the result of her feeding him berries that stained his tongue. Katara sadly confessed her actions and the assumption of her identity as the Painted Lady. She apologized for delaying them, however, Aang stated his approval of the idea. Together, the two infiltrated the factory and destroyed it, stopping the flow of the polluted sludge.
Upon returning to the campsite, they realized Toph and Sokka had unfolded their plot. As they prepared to leave, they caught sight of a squad of Fire Nation troops heading toward the town on speeders and realized they must believe the villagers had sabotaged the factory. Determined to stop them, Katara and Aang, with help from Appa, Toph and Sokka providing spooky sound effects, staged an encounter with the Painted Lady to defeat the troops and drive them away.
The team stayed behind long enough to help the villagers clean the Jang Hui River. That night, as Katara examined the water, a thick mist appeared and the real Painted Lady appeared to express her gratitude.
Meeting Piandao Edit
Katara and the others witnessed a meteor shower one night when a meteorite suddenly soared past them and collided into the earth, resulting in a fire. With a village lying nearby, the team raced to the scene of the incident to extinguish the fire. Katara used waterbending to douse the flames.
After successfully extinguishing the fire, Sokka began to brood on the fact that he did not possess bending abilities as opposed to the rest. Katara suggested they go shopping to cheer him up. When he discovered a sword to his liking in the weaponry store, the shop owner informed him it was crafted by the greatest sword master and sword maker in Fire Nation history, Piandao, who lived nearby. Katara suggested to Sokka to study under him. Sokka took her advice and traveled to Piandao's castle to learn the ways of the sword while Katara, Aang and Toph waited impatiently for his return. He later returned, appealing for help in taking the extinguished meteorite to Piandao's palace where he proceeded to craft his own sword.
When Piandao presented him with his meteorite sword, Sokka revealed he was from the Water Tribe, not the Fire Nation. When Piandao suddenly engaged him in a duel, the others ran to Sokka's aid only to be halted by their friend, who claimed this to be his fight alone. Katara, Aang and Toph witnessed the duel, eventually resulting in Piandao's overpowering of Sokka. Sensing him to be in danger, they rushed to his aid only to be paused by Piandao who praised his skills and signals the end of the battle. The swordmaster revealed his knowledge of Aang being the Avatar and Sokka hailing from the Water Tribe and addressed Sokka himself, claiming he would gradually become a more superior swordmaster. The team soon departed from the palace.
Encountering Combustion Man Edit
Katara and the others rested in an isolated quarry where Aang unknowingly revealed his identity to two Fire Nation soldiers patrolling the area nearby. Stunned to discover the Avatar was secretly alive, they sent a message to the Fire Lord on a messenger hawk; however, the journey was intercepted by a raven eagle owned by Combustion Man, the assassin Prince Zuko hired to eliminate Aang. That night, while sleeping, Combustion Man attacked them, using a special firebending technique that enabled him to shoot fire from his third eye. A short duel is fought and Aang narrowly escaped with his friends on Appa.
Aang and his friends traveled to the island that was once Avatar Roku's home, after Roku himself approached Aang in a dream. Once there, Aang meditated and ventured into the Spirit World. At one point, Katara asked Sokka whether there were bathrooms in the Spirit World to which Sokka replied that there were not. When Aang returned to the physical world and told of his adventure with Roku, Katara expressed shock at learning how Fire Lord Sozin betrayed Roku. She, along with the others, held hands at the end.
Arguing and working with Toph Edit
The team briefly resided near a Fire Nation Fountain City where Toph began using her earthbending skills to scam local residents for money. Katara immediately became displeased with Toph's behavior, accusing Toph's motive behind her actions as an attempt to avoid thinking about her parents whom she ran away from. When Katara discovered a wanted poster of Toph, nicknaming her "The Runaway", things only grew worse.
Another argument broke out between the two with Toph ranting about how Katara was acting too motherly which upsets the latter greatly. Later, while bathing in the water, Katara overheard a conversation between Toph and Sokka. Sokka confessed to Toph that although Katara did become bossy at times, the maternal role she took on when their mother died was so great that he had since then replaced his image of his mother with his sister's face. Toph also revealed that she thought Katara's bossy nature was not always bad, as Katara actually cared about who Toph really was, which was more than even her own mother did for her.
Katara was deeply touched by this conversation and later devised a scam with Toph, much to everyone's surprise. Things did not turn out the way she had expected, however, when both she and Toph became imprisoned in a wooden cell by Combustion Man. Fortunately, Katara discovered a technique she can use to escape: sweat manipulation. By bending her sweat, she was able to slice through the wooden cell and escaped with Toph. The relationship between the two was finally mended when Katara agreed to help Toph send a letter to her parents.
Meeting Hama and learning bloodbending Edit
As the team continued on their journey, they stopped in a forest and started telling ghost stories. Sokka told one about a haunted sword which failed to scare anyone. Katara proceeded to tell a story of her mother's friend, Nini, who mysteriously disappeared during a snowstorm, which managed to frighten everyone. Toph suddenly stated she heard screaming coming from under the mountain only for the noise to abruptly cease. An old woman named Hama suddenly appeared, offering them a safe place to stay for the night. The group accepted her offer to stay at her inn where they learn of mysterious disappearances occurring on nights of the full moon.
The next day, Hama led her guests on a shopping trip, wherein Sokka overheard some of the locals talking about the disappearances during the full moon. When Hama sent her guests back to the inn, Sokka investigated the house for anything suspicious. Their search resulted in the discovery of a cupboard of wooden puppets and a small chest lying in an empty room in the attic. Before they managed to open the box, Hama walked in and caught them in the act. The team surrendered the chest where Hama proceeded to open it herself, revealing there to be a Whale tooth comb stored inside. She claimed it to be her greatest treasure and last possession she owned from being raised in the Southern Water Tribe. She went on to explain her knowledge of Katara and Sokka being raised in the Southern Tribe as well, a revelation that stunned the team.
During dinner that night, Hama revealed herself to be a waterbender and a victim of the devastating Southern Water Tribe raids, having been captured as a young woman and detained in a facility specifically designed to hold waterbenders. Hama also revealed to be the only one who managed to escape, but was too upset to explain more. She offered to tutor Katara in order to carry on the tradition of the Southern waterbenders to which the young waterbender happily agreed, wanting to learn more about her tribe's cultural heritage. The next day, Hama personally trained Katara and explained to her that water can be found in unexpected places. She demonstrated to her several useful techniques including the manipulation of water vapor and the ambient channeling of water from fire lilies, flowers native to the Fire Nation. She told Katara of one more technique she had to teach, one that could only be utilized under the full moon. When Katara expressed hesitance due to rumors of the disappearances, Hama reassured her, stating that two master waterbenders beneath a full moon should be able to handle anything.
That night, Hama took Katara into the woods where the alleged disappearances have occurred. She recounted her time spent in prison and discovery of a dark technique known as bloodbending, controlling the water in another body, which could only be used under the influence of the full moon enhancing her abilities. Horrified by the idea of controlling another person's body, Katara refused to learn bloodbending. This led Katara to realize that Hama had been causing the villagers to disappear, but Hama angrily stated that the people of the Fire Nation deserve the same treatment that they gave to the Southern waterbenders. Hearing this causes Katara to adamantly refuse to learn bloodbending and attempted to stop Hama from further terrorizing the town.
Hama used the technique to temporarily force Katara into submission, however, the latter quickly regained control of her body, telling Hama that she not only draws power from the full moon as well, but her bending was far more powerful. The two began to battle, each drawing water from the grass and trees surrounding them; it quickly became obvious that they were equally matched. When Katara seemingly gained the upper hand, Aang and Sokka arrived to assist her. Hama, using bloodbending, sent them flying at first Katara and then at each other, with Sokka's sword pointing straight at Aang. At the last second, Katara used bloodbending to subdue Hama and protect Aang and Sokka. Toph arrived with the other villagers, who handcuffed Hama and took her away, vowing to imprison her forever. Hama remarked that her work is done, as Katara had already willfully used bloodbending and laughs as she was dragged off. Katara then broke down in tears, with Aang, Sokka and Toph's comfort.
Days before the invasion Edit
Within the following days, Katara and the rest of the team arrived to the uninhabited Black Cliffs located in the Fire Nation, the rendezvous point for the entire invasion force. Aang learned there were only four days left until the invasion and felt unprepared, having not learned firebending. He started having nightmares about his duel with Fire Lord Ozai and trained relentlessly, depriving him of sleep. He started having hallucinations and grew increasingly tired, so Katara and the others attempted to help. Katara attempted to relax Aang with a few yoga sessions inside a nearby soothing hot spring. However, the heat from the water reminded Aang of the Fire Lord's firebending, causing him to panic even more. When Aang continued to train nonstop, Katara managed to persuade him to sleep for a while. The day before the invasion, Aang talked to Katara, telling her his lack of sleep had helped him to realize that while he was fighting the Fire Lord to save the world, he was also doing it for her. He confessed that he loved her and kissed her passionately. However, this turned out to be a mere hallucination, with Aang having to explain his behavior to a confused Katara by lying that he daydreamed about living underwater, much to her amusement. He suffered a severe hallucination later that day, prompting Katara and her friends to shave an entire herd of koala sheep and use their wool to create a large bed for Aang. When he refused to sleep due to his lack of confidence in the upcoming battle, Katara reassured him that he was prepared to fight. She recounted that since the day they met, Aang had trained for this battle and had become incredibly strong, brave and smart, displaying great prowess in battle and a great love for his friends and allies. Because of Katara and the others, Aang finally got some decent sleep, now fully confident in his ability to defeat Ozai.
The Invasion and the eclipse Edit
The day of the Invasion arrived at last with many former allies and familiar characters reuniting with Team Avatar. During the Day of Black Sun, Katara assisted in the operation of the Mechanist's submarines, utilizing waterbending to control their buoyancy. When they resurfaced, she stated her pride in Aang, saying he was no longer the goofy kid she rescued from the iceberg. Aang suddenly kissed Katara, to which she reacted by leaning in. He left on his glider and she proceeded to jump on Appa and continued along with the submarines on their journey toward the Fire Nation.
Katara assisted in the battle against the firebenders, proving to be a worthy foe in combat once again. When her father was severely injured, she used her healing abilities to heal him, giving him the strength needed to carry on. Katara did not join Sokka, Toph and Aang in their pursuit of Fire Lord Ozai, opting instead to help her father move around. She and the troops secured the Royal Palace, the invasion failed when Princess Azula distracted Aang during the eclipse, forcing the group to retreat. To make matters worse, the entire force could not escape because the Fire Nation destroyed their submarines, so Aang and all of the younger members of the force fled to the Western Air Temple while the elders surrendered. Katara gave Aang a look of reassurance when he cried over the failure of the battle.
Katara and the group arrived at the Western Air Temple and began discussing who would be Aang's firebending teacher. She suggested Jeong Jeong, but Aang retorted this suggestion, saying there was no way of finding him again. When Zuko showed up at the Temple, Katara became enraged and prepared to attack only for Zuko to announce that he had changed and now wanted to teach Aang firebending. Katara was the most opposed to trusting him and attacked him using waterbending when he insisted that he be taken as their prisoner. Katara later confessed to the gang that when she and Zuko were imprisoned in Ba Sing Se, he won her sympathy for him when he lamented the loss of his mother, Ursa; when he betrayed her by joining Azula, she vowed never to trust him again. Toph pointed out to the group that Zuko was being honest in his apologies over his past crimes and that he was the only available person to teach Aang firebending. However, Katara and the others shot her down with their disinterest, causing Toph to storm off.
The next day, Toph returned to reveal that Zuko had burned her feet when she tried to talk to him about joining the group. It was an honest accident as he had mistaken her for an attacker, but the fact that he used firebending on her was enough to convince Sokka and the others to hunt Zuko down. While tending to Toph's wounds, Combustion Man attacked, pinning the group down. Katara and Aang's attacks proved useless, however, Zuko bought the gang enough time for Sokka to defeat the assassin with his boomerang. Zuko apologized once again to the group for his misdeeds and proved to the gang that he had in fact changed for the better. Aang, Toph and Sokka immediately saw the good in Zuko and accepted him, however, Katara only allowed him to join because of Aang's need to learn firebending. Zuko became clearly nervous when she pondered her choice, knowing full well that she had little reason to trust him. Katara later confronted Zuko in his room in the temple.
- "You might have everyone else here buying your... 'transformation', but you and I both know you've struggled with doing the right thing in the past. So let me tell you something right now: you make one step backward, one slip-up, give me one reason to think you might hurt Aang and you won't have to worry about your destiny anymore, because I'll make sure your destiny ends, right then and there; permanently!"
- ―Katara fiercely threatening Zuko.
In other words, if she detected any act of treachery, she would not hesitate to take his life. She then left a very stunned and silent Zuko to ponder on these scathing words.
She still expressed hostility toward Zuko, openly mocking his loss of firebending and the irony that if he had lost his skills long ago, it would have helped them greatly. Her hostility toward Zuko did lessen somewhat; she mocked him after he failed to tell a joke properly, but in a less vindictive way.
Trusting Zuko Edit
Later, a fleet of Fire Nation airships led by Azula assaulted the Western Air Temple. When a bomb struck the ceiling, a number of heavy stones fell to the ground, nearly crushing Katara, until Zuko saved her. This act irritated her, however, and she ungratefully shoved him off her. The group attempted to escape through a tunnel, while Zuko held off Azula and the fleet. When they were unable to get Appa through the tunnel, Sokka suggested they split up. Katara fiercely objected, arguing that the Fire Nation should not be allowed to break up their family again. Hakoda reassured her they would not be apart forever and bid farewell to Katara and Sokka. Katara and the gang escaped on Appa; she even saved Zuko when he fell off Azula's airship.
Later, the group camped out on an unnamed island and celebrated Zuko's heroism. Katara, however, did not enjoy the celebrations, or Zuko's joke about trying to capture them. When Zuko said he did not deserve their praise, Katara agreed with him and stormed off. Zuko followed her and said that her continued animosity was not fair as everyone else trusted him. She angrily replied that she was the first person to trust him and he betrayed her. When he asked how he can make up to her, she angrily said:
After a discussion with Sokka, Zuko discovered the Southern Raiders were the ones responsible for Sokka and Katara's mother's death. He waited outside Katara's tent until she awakened and offered to help her track down her mother's murderer.
A furious Katara took up the offer. When they asked Aang if they could borrow Appa, Aang jokingly asked whether it was Katara's turn to take a field trip with Zuko. When Katara confirmed this, Aang asked as to what was happening. Zuko revealed to him and Sokka that he knew who murdered Katara's mother and that they intended to find him. An argument ensued, with Zuko and Katara claiming that she needed to achieve emotional resolution, while Aang and Sokka both claimed it to be a bad idea as both violence and vengeance were never the answer. The argument ended with Katara angrily storming off. That night, Katara and Zuko sneaked out to take Appa anyway; Aang unfolded their scheme, however, he allowed them to embark on the journey. Before departure, he urged Katara not to kill the man who killed her mother, but to forgive him.
She and Zuko ventured to a Fire Navy communication tower. After infiltrating the tower, they found the scroll showing the Raiders' whereabouts, at Whaletail Island. Katara guided them there in a day's time without rest and told Zuko what she remembered of her mother's death.
When they arrived at the Southern Raiders' ship, on the night of a full moon, Katara effortlessly took out almost all the ship's crew. The two of them forced their way toward the leader, with Katara blasting a metal door open with waterbending. When the leader fought back and firebent at Zuko, she willingly used bloodbending to subdue him. After looking him in the eyes, however, she realized that he was not the same man who had killed her mother. When Zuko interrogated him, he revealed the man they were searching for is Yon Rha, the former leader of the Southern Raiders who had retired four years ago when Katara was ten years old.
She and Zuko traced his whereabouts to a Fire Nation village and ambushed him. After several harsh demands from Katara, Yon Rha realized she was the Water Tribe girl he had seen six years ago. He revealed that he had been ordered to find and kill the last waterbender of the Southern Water Tribe and that Katara's mother had claimed it was her. An enraged Katara said her mother had deliberately lied to protect the last Southern waterbender: herself. She then created a dome from the rain; she proceeded to transform the water into dozens of ice spikes, which she hurled at the man, intent on finishing him. However, she halted at the last minute. Yon Rha pleaded with her to spare him and even offered his own mother's life in exchange. Katara merely stated she realizes how sad, pathetic and empty he was, going on to reveal that no matter how much she hated him, she could not kill him. She and Zuko left, while Yon Rha cried. When they rejoined the group, Aang said he was proud of her for forgiving Yon Rha. Katara replied that she had not forgiven him; however, she did forgive Zuko and gave him a warm hug, thawing any remaining bitterness.
The Ember Island Players Edit
The gang retreated to Ozai's old beach house where Zuko and Aang continued their firebending training. Katara questioned if it was safe to hide from the Fire Lord in his own beach house, a concern Zuko quickly dismissed. Sokka and Suki arrived, suggesting the group went to see a play about themselves to which the others reluctantly agreed. Like all the others, with the exception of Toph, Katara was displeased with her portrayal. Her character was played by a much older and more developed actress and portrayed as very melodramatic and exaggeratedly preoccupied with hope, often bursting into tears and histrionic speeches for the occasion. In one such scene, when Sokka asked Katara why she stole the waterbending scroll, she answered while crying, "It just gave me so much hope", much to the dismay of the real Katara. When the play reached the point where Zuko betrayed Iroh, Katara asked an upset Zuko if he did in fact state that he "hates his uncle". A sullen Zuko replied that he might as well have.
The play continued and portrayed the scene involving Katara and Zuko's time spent imprisoned in the Crystal Catacombs of Ba Sing Se, with Actress Katara hitting on Actor Zuko, making their real life counterparts slightly uncomfortable. When Actor Zuko claimed her to be the Avatar's girl, Actress Katara assured him the Avatar was merely a brotherly figure and one she did not love romantically; the two proceeded to embrace. Aang became enraged and stormed off. During intermission, Katara found Aang sulking outside; Aang stated his true feelings for her only for Katara to confess her current confusion. She admitted that she was not seeking to be in a relationship at the moment. When Aang suddenly kissed her, she became upset, noting her confusion and went inside, leaving Aang heartbroken.
Like the rest of the group, Katara was displeased with the ending to the play with the Fire Nation emerging victorious in the War.
Sozin's Comet Edit
When Zuko berated the others for having beach parties when the comet was three days away, Katara stated the Fire Nation had, in essence, won the Hundred Year War when they conquered Ba Sing Se. She revealed the team's plan to wait until after Sozin's Comet to battle the Fire Lord. Dismayed, Zuko revealed Ozai's plan to burn the Earth Kingdom down with enhanced firebending and warned Aang that he needed to defeat the Fire Lord before the comet arrived if he still wanted there to be a world to save. The following day, the group discovered that Aang and Momo were missing and searched the entire island. Their mission turned up unsuccessful, so they turned to Zuko, who had experience in tracking Aang down. The group flew to the Earth Kingdom, where Zuko asked June to track Aang down using the scent of his glider. When her shirshu was unable to do so, he instead asked that she found Iroh, offering one of his smelly sandals for guidance. June tracked him down to Ba Sing Se and left. During the evening, the group was approached by members of the Order of the White Lotus, namely Pakku, who revealed himself to be Katara and Sokka's step-grandfather, having married Kanna. Alongside him were other White Lotus masters the group had met before: Bumi, Jeong Jeong, and Piandao. They took them to the Order's campsite, where they met Iroh. It was later decided that Katara would return to the Fire Nation to help Zuko usurp the throne from Azula when Ozai was defeated.
The two left on Appa and headed toward the Fire Nation. On the way there, Katara tried to reassure Zuko's worries of Aang not being able to defeat the Fire Lord, despite being concerned herself. They arrived at the Fire Nation Capital during Azula's coronation where the princess challenged Zuko to an Agni Kai to which he accepted. While Katara watched the battle from the sidelines, Zuko dueled Azula, eventually gaining the upper hand. When he mockingly asked Azula whether her refusal to generate lightning is due to a fear of him redirecting the bolt, she took the bait and generated lightning. Instead of targeting Zuko, she aimed and fired the attack at Katara. Zuko barely blocked the lightning, saving Katara's life, but took the blast to his chest, injuring him badly. Katara tried to heal her friend, but was thwarted in her attempts by Azula. Katara then proceeded to fight Azula who attempted to drive her away from any source of water. She eventually managed to trick Azula into walking directly over a grate of water. Freezing her in a mass of ice, Katara was able to chain the princess to the grate before rushing to Zuko and healing him. Zuko thanked her, to which Katara stated it was she who should express gratitude toward him. She was present at Zuko's coronation, after the team's successful victory in the century-long war.
She was later seen at the Jasmine Dragon, along with the other members of Team Avatar and followed Aang after he left for some fresh air, going on to hug him. She and Aang then looked at each other lovingly before she instigated a romantic kiss.
