In The Last Airbender, a fictional universe composed of four sovereign nations, the Avatar—a being who represents the bridge between the physical and the spirit worlds—alone holds the power to master all four elemental powers, but has been missing for the past 100 years. During this absence, a war started by the Fire Nation resulted in the Air Nomads' genocide, the Southern Tribes' waterbending population near extinction, and the Earth Kingdom's extensive colonization. In The Legend of Korra, set 70 years later, Republic City, the capital of the United Republic of Nations, serves as the primary setting for the repercussions of said wars, leading to events such as the Equalization movement for non-benders, Harmonic Convergence of the spirit world, civil war in the southern polar region, and the reunification of the fractured Earth Kingdom.
Character designs were originated from a series of drawings by one of the show's creators, Bryan Konietzko. The main sketch depicted a middle-aged monk with an arrow on his head and later included a flying bison as his pet. Konietzko's partner, Michael Dante DiMartino, was interested in documentaries related to the South Pole at the time. They combined these ideas and created the concept of an "air guy" and "water guys" trapped in a snowy wasteland, with "fire guys" invading them. Additionally, the writers based the characters' different bending abilities on distinct styles of martial arts.
The characters of Avatar: The Last Airbender were designed by Michael Dante DiMartino and Bryan Konietzko, the co-creators of the series. The anime-styled character art was inspired by Shinichiro Watanabe's Cowboy Bebop, Samurai Champloo, and FLCL (Fooly Cooly) of Gainax. The original character conception was derived from a sketch by Bryan Konietzko that depicted a middle-aged balding man with an arrow on his head. Studios such as Studio 4°C, Production I.G, and Studio Ghibli, which produced anime-styled cartoons, were also sources of inspiration.
The greatest influences on the series were Asian art and history; the characters' various personalities and traits are based on philosophical teachings such as Taoism and Buddhism. In the show, some characters have the ability to manipulate one of the four classic elements of ancient philosophy: Water, Earth, Fire and Air, although the Avatar has the ability to control all four. Each of these employ a different form of martial arts in their fighting choreography: T'ai chi for Waterbending, Hung Gar for Earthbending, Northern Shaolin for Firebending, and Ba Gua Airbending. These individual styles of martial arts also reflect on the personalities of the user and the nations as a whole. These starkly individual tendencies are explained in eighty-five distinct types of "Jings", or internal energy. For example, Ba Gua employs the "negative jing" to create erratic circular movements and capitalizes on centripetal force and defensive positions while Northern Shaolin follows the "positive jing" and emphasizes brute strength and aggression to generate power. The negative jing reflects Aang's bending styles and his tendency to be unpredictable and extremely carefree, as well as his pacifist and non-aggressive nature.
Many of the recurring characters of the series have received traits based on the respective element. Aang is carefree and childlike, as is commonly attributed to "wonder" of the unknown, or the "freedom" of the wind and the air. As a spiritualist, a pacifist and a vegetarian, he is very Yin and notably feminine, hyper-attuned to the spirit world, and prefers non-violent alternatives to solving problems. Unlike her predecessor Aang, Korra is very Yang and distinctly masculine; she was inspired by various female MMA fighters and is "very tough, very headstrong, and not scared to get into a fight," as attributed to Water's attributes. Her stubborn realism and hot-headed personality prevents her from easily learning airbending or connecting with the Spirit World. Toph, despite being blind, is extremely perceptive of the world around her due to her connection to the Earth. Unlike Aang, she is extremely brusque when criticizing others, as attributed to Earth's toughness.
The Last Airbender principal characters
Avatar Aang (Chinese: 安昂; pinyin: Ān Áng) (voiced by Mitchel Musso in the unaired pilot, voiced by Zach Tyler Eisen in Avatar: The Last Airbender, voiced by D. B. Sweeney in The Legend of Korra, and portrayed by Noah Ringer in The Last Airbender) is the protagonist of the original series, and in it, the current Avatar, a being who exists through reincarnation to maintain world balance. A reluctant hero, Aang often acts in a fun-loving, carefree manner. His pacifism and vegetarianism demonstrates his love for life, a primary trait of Buddhism. The creators intended Aang to "defeat enemies with his wits" and be a "trickster hero". Though Aang is often frivolous and enthusiastic, he becomes serious during a crisis.
In the original series, Aang is rescued from a century of suspended animation by Katara and Sokka. Having already mastered his native Airbending, Aang learns Waterbending at the North Pole in Book One and continues his instruction from Katara in the rest of the series, Earthbending from Toph in Book Two, and Firebending from Zuko in Book Three. Throughout the series, Aang comes to the aid of Water Tribes and Earth Kingdom communities oppressed by the Fire Nation. Unwilling to kill Fire Lord Ozai, despite his past Avatar incarnations insisting on it, Aang ultimately learns the ancient Lion-Turtles' technique of energybending, which allows the user to give or take away a person's bending, and uses it to render Ozai a non-bender.
In The Legend of Korra, is revealed that Aang aided Zuko in creating the United Republic of Nations. He also married Katara and had three children, with his youngest son Tenzin restoring the Air Nomads while instructing his reincarnation Korra. Like Roku before him, Aang appears at times before his reincarnation Korra prior to their connection being destroyed.
- Appa (Chinese: 阿柏; pinyin: Ā Bǎi) (voiced by Dee Bradley Baker in the original animated series) is Aang's male flying bison, animal guide and spirit companion. He serves as the group's Mode of transport around the world. He possesses the ability to fly and can use his tail to create powerful gusts of air. According to Aang, flying bison were the first Airbenders. The show's creators, Michael Dante DiMartino and Bryan Konietzko, have described Appa's appearance as a cross between a bison and a manatee. He is known to shed his coat at the end of winter.
- Momo (Chinese: 模模; pinyin: Mò Mò) (voiced by Dee Bradley Baker in the original animated series) is the only known Winged Lemur. Avatar: The Last Airbender co-creator Bryan Konietzko admits that Momo is his favorite character to draw and that his body language is derived from memories of a childhood cat. Momo was introduced when Aang finds him at the Southern Air Temple and then keeps him as a pet. Although Momo has been in many dangerous situations while traveling with the protagonists, he has also been of aid to them and a source of comic relief throughout the series. According to the creators, Momo was intended to represent the spirit of Monk Gyatso, Aang's mentor. Momo is a cross between Bat and a Lemur and is the last of his kind in the show much like Appa (though it is possible based on the descriptions by the Pirate Captain in "The Waterbending Scroll" and by Tho in "The Swamp" that a few more of his kind may exist in captivity and circuses elsewhere in the Four Nations). Momo was introduced in the episode "The Southern Air Temple". In the episode, Aang finds Momo at the Southern Air Temple and then keeps him as a pet. After Momo eats a peach, Aang decides to name him Momo, which is Japanese for "peach". In the series Momo has been a recurring part of the team.
Prince Zuko, later Fire Lord Zuko (Chinese: 祖寇; pinyin: Zǔ Kòu) (voiced by Dante Basco in the original animated series, voiced by Bruce Davison in the sequel series, and portrayed by Dev Patel in the live-action film) is a central character: the primary antagonist of Book One, an anti-hero of Book Two, and a protagonist in Book Three. Throughout Book 1, he has a shaved head with ponytail. In Book 2, he cuts it off and grows his hair. In Book 3, his hair is shoulder length.
When exiled, prior to the beginning of the series, by his father Fire Lord Ozai for forfeiting a duel therewith, Zuko believed that capturing the Avatar would regain his honor. In addition to his firebending, Zuko is proficient in the use of double broadswords wielded in his alter ego of the "Blue Spirit". Zuko's ancestry reflects his own anxieties, in that his paternal great-grandfather Fire Lord Sozin started the war while his maternal great-grandfather Avatar Roku attempted to prevent it. In Book One, Zuko fails many times to capture the Avatar, and in Book Two, Zuko and his Uncle Iroh earn further displeasure when they flee into the Earth Kingdom, where he befriends locals and goes so far as to rescuing them from corrupt Earth Army guards. When tempted by his sister Azula's offer of honor's restoration, he betrays his uncle to assist Azula's fight against the Avatar. In Book Three, Zuko eventually rejects his father Ozai's plans. After he learns the secret of Firebending with Aang from two dragons, he becomes Aang's Firebending teacher; helps Sokka rescue prisoners; assists Katara in confronting her mother's killer; and receives his uncle Iroh's forgiveness. After defeating Azula, Zuko becomes the new Fire Lord and ends the war.
The sequel series reveals that Fire Lord Zuko aided Avatar Aang reorganizing the Fire Nation's colonies in the Earth Kingdom as a United Republic of Nations, and is the only one of Republic City's founders not to have lived there. After abdicating the throne in favor of his daughter Izumi while her son Iroh later serves as a general in the United Forces, Zuko travels the world as an ambassador for peace and keeping major threats in check while Aang's reincarnation Korra was still a child.
Katara (Chinese: 卡塔拉; pinyin: Kǎ Tǎlā) (voiced by Mae Whitman in the original series, voiced by Eva Marie Saint in the sequel series, and portrayed by Nicola Peltz in the live-action film) is Aang's best friend, later becoming his girlfriend and ultimately, his wife.
In the original series, she had mastered the art of waterbending at the end of Book One, and therefore began teaching Aang the art alongside his study of earthbending in Book Two. Katara is known for resisting gender stereotypes; but acts as den mother to the other protagonists. As a waterbender, she is able to heal injuries, change water into ice, and use it to cut through solid objects. She is known to become enamoured easily, and is often angered by treachery or dishonesty. She also learns bloodbending, the manipulation of liquids within a living creature, in Book Three.
In the sequel series, Katara is revealed to have married Aang and had three children. In an earlier version of the pilot episode, Katara's name was Kya: a name later re-used as her mother's name and later that of her daughter. In the sequel series, Katara is Korra's Waterbending master.
Sokka (Chinese: 索卡; pinyin: Suǒ Kǎ) (voiced by Jack DeSena in the original series, voiced by Chris Hardwick in the sequel series, and portrayed by Jackson Rathbone in the live-action film) is a 15-year-old warrior of the Southern Water Tribe, and Katara's elder brother. With no bending power of his own, Sokka relies largely on a metallic boomerang, a blunt metal club, a machete, and later a black jian created from the metals of a meteorite. Surprisingly in an inhabitant of a mystical world, Sokka is an engineer and something of a jack-of-all-trades, in which respect he is easily able to understand the Fire Nation's advanced technology, and perfects the design of the hot air balloon. In addition, he is both heterodox and resourceful in his endeavors, and a source of comic relief throughout the series. Sokka was in love with the Northern Water Tribe princess Yue at the end of Book One and later shifted his affections to the Kyoshi Warriors' leader Suki in Books Two and Three.
In the sequel series, flashbacks reveal Sokka was the first representative of the Southern Water Tribe to sit on the Republic City Council, and possibly its first chairman. He died a few years after Aang, when the next Avatar, Korra, was still a child.
Toph Beifong (Chinese: 北方拓芙; pinyin: Běifāng Tuòfú) (voiced by Jessie Flower in the original series, voiced by Kate Higgins in Books One and Three of the sequel series, and by Philece Sampler in Book Four) is a blind Earthbending grandmaster of the prestigious Bei Fong family in the Earth Kingdom.
In the original series, Toph helps Aang master Earthbending after leaving her home. Toph is often sarcastic, direct, and confrontational; commonly depicted as the choleric and tomboy of the group. Though blind, Toph has the ability to "feel" vibrations in the earth, be it the presence of trees and buildings or the march of ants several meters away. Through this heightened sense, she can identify people's locations, their distance from her, and their physical build. This 'seismic sense' provides her with a distinct advantage when facing other Earthbenders in combat, as they characteristically require contact with the ground and extract rocks from their surroundings. As another result of her blindness, Toph has an acute sense of hearing, enabling her to recognize people by the sound of their voices and to eavesdrop on distant conversations. Unlike other Earthbenders, Toph has a distinct style of earthbending not based on Hung Gar but on the Southern Praying Mantis, featuring quick generation of energy and low kicks, to suit her small stature. Toph taught herself metalbending by manipulating the metals' impurities at the end of Book Two and throughout Book Three.
In the sequel series, flashbacks reveal that Toph was the first Chief of the Metalbending Police Force, the police department of Republic City. Toph eventually became a single mother of two daughters: Lin, who eventually succeeded her mother as police chief, and Suyin, who founded a commune of free-thinking Earth and metalbenders known as Zaofu. By the time the series begins, having once lived with Suyin's family in Zaofu, Toph took residence in the Foggy Swamp where she assists Korra.
General Iroh (Chinese: 艾洛; pinyin: Aì Luò) (voiced by Mako in Books One and Two, voiced by Greg Baldwin in Book Three and sequel series, and portrayed by Shaun Toub in the live-action film), also known as "The Dragon of the West", is a Firebending master and former heir to the Fire Nation throne. After the death of his son at the Siege of Ba Sing Se, his younger brother Ozai superseded him as Fire Lord. Unlike most firebenders, Iroh lacks hostility toward other nations and generates his fire and lightning not from fury, as is conventional, but from a sense given to him by dragons, the original source of firebending. As a member of the Order of the White Lotus, Iroh has social connections throughout the Four Nations. Iroh is outwardly easy-going and friendly, and particularly fond of food, good tea, the strategy game Pai Sho, cheerful company, and pleasant music. Something of a hedonist in his old age, he focuses more on relaxation and amusements than on the pursuit of the Avatar, a habit that clashes with the obsessions of his nephew Zuko. At the end of the series, after enlisting his fellow White Lotus members to release Ba Sing Se from the Fire Nation's rule, Iroh reopened his tea shop within the city.
In The Legend of Korra sequel, near the end of his life, Iroh transferred his soul into the Spirit World where he offers his assistance to Aang's reincarnation Korra, and later to Aang's children Tenzin, Kya, and Bumi during their initial visits to the Spirit World. Iroh is also the namesake of Zuko's grandson.
Princess Azula (Chinese: 阿祖拉; pinyin: Ā Zǔ Lā) (voiced by Grey DeLisle in the animated series and played by Summer Bishil in the live-action movie) is Zuko's sister who is a major antagonist in Book Two and Book Three. She is a gifted Firebending master. After Zhao's death, Azula is sent by Ozai to capture the Avatar, Zuko, and Iroh. Her amorality and ability to act without hesitation or remorse also accounts for her ability to create lightning, a skill that requires peace of mind. Despite her cruel temperament, she becomes distraught when abandoned by her friends Mai and Ty Lee, and collapses mentally when her father leaves her the now-worthless position of Fire Lord, in which she becomes increasingly irrational, paranoid, and mentally unstable, and ultimately suffers a full psychotic breakdown, in which she is overcome by Zuko and Katara.
Following the end of the war, Azula is placed at a mental institution to be closely monitored. As revealed in the comic sequel, The Search, Azula managed to convince Zuko to let her accompany him in the search for their mother. But in reality, her madness tied to the hatred she bears towards her mother, Azula's reasons were to eliminate Ursa upon finding a letter that claimed Zuko to be only her half-brother and thus making her the legitimate heir to the throne. But after her attempt to kill her mother failed, and unable to accept Zuko still caring for her after everything she had done to him, Azula fled into the Forgetful Valley before the letter's contents were later revealed to be false.
The Legend of Korra principal characters
Avatar Korra (Chinese: 寇柆 pinyin: Kòu Lā) (voiced by Janet Varney and by Cora Baker as a child) is Aang's immediate incarnation in the sequel series The Legend of Korra. While more confident and energetic than her past life, Korra lacked a connection to the spiritual world. Through her confrontations with Amon (the son of an enemy of Aang's), her uncle Unalaq (who became a Dark Avatar through Raava's counterpart Vaatu and severed Korra's ties to her past lives), and Zaheer (leader of the anarchistic Red Lotus who believed the Avatar's death is needed for people to have freedom), Korra realizes a commonality as they were unbalanced despite their noble intentions. This allows her to peacefully resolve matters with the totalitarian despot Kuvira. In this way, despite the contrasts between her and Aang, Korra's progress in becoming a better person mirrored Aang's journey in a way. As with Avatar: The Last Airbender, Korra's story ends with the supposition of a romantic relationship, in this case with Asami Sato, a member of the Team Avatar of her lifetime.
- Naga is a female polar bear dog that belongs to Avatar Korra as her animal guide and spirit companion and main form of transportation. Despite her intimidating appearance, Korra describes Naga as a "sweetheart" and regards her as her best friend. Undyingly loyal, she is protective of Korra and her friends and has learned how to use her strength to help them out of perilous situations
Asami Sato (Japanese: 佐藤 麻美, Hepburn: Satō Asami) is an elegant, intrepid young woman with unwavering loyalty to her friends and allies. The only child of the former wealthy industrialist, Hiroshi Sato. Although a nonbender, when she discovered that her father was working with the Equalists, she rejected his hatred of benders and actively fought against the Equalists as a member of Team Avatar. After her father's imprisonment, she became the new Chief Executive Officer of Future Industries, planning to bring the company back to the peak of economic dominance and restore its reputation. Two weeks after Harmonic Convergence, she joined her friends in the search for the new airbenders. However, their search stopped when the Red Lotus attempted to kidnap Avatar Korra in Zaofu and they worked to bring the organization down instead. Three years later, in 174 AG, Asami assisted in defeating Kuvira and it is hinted that she began a romantic relationship with her best friend, Korra.
Bolin (Chinese: 愽林 pinyin: Bó Lín) is an earthbender from a multicultural family. He grew up on the streets of Republic City under the protection of his older brother, Mako, after their parents were killed by a firebender. Eventually, he and his brother founded a pro-bending team, the Fire Ferrets, that would later include Avatar Korra. After the Pro-bending Tournament ended, Bolin joined Team Avatar in an attempt to stop the Equalist organization.
In the following months, Bolin quickly became close friends with the Southern Water Tribe industrialist Varrick and starred in The Adventures of Nuktuk: Hero of the South, a propaganda film series created by Varrick in an attempt to drum up support for the Southern Tribe within Republic City during the Water Tribe Civil War. After reuniting with Team Avatar, Bolin attempted to help his friends stop Chief Unalaq from merging with Vaatu, the spirit of darkness, during Harmonic Convergence.
A few weeks after Harmonic Convergence, Bolin and his friends traveled around the Earth Kingdom to search for airbenders. At one point, the group had to flee from Ba Sing Se and split up from Tenzin. They continued their search until the Red Lotus attacked Zaofu, at which point they instead worked to combat the anarchist organization.
After bringing down the Red Lotus, Bolin began a relationship with Opal and joined Kuvira in her goal of reuniting the divided Earth Kingdom with military force with the rank of corporal, believing it gave him the opportunity to help others. He eventually realized, however, that there was a darker side to the army's actions, which prompted him to desert, though he was apprehended. However, he managed to escape with Varrick, leaving the army to believe they were dead for a while, and rejoined Team Avatar in Republic City to help them defeat Kuvira, while rebuilding his relationship with Opal.
- Pabu is a mischievous male fire ferret who belongs to Bolin. Although he often gets into trouble, his agility and sharp teeth make him dependable in sticky situations. He has been Bolin's partner in crime on more than one occasion. He is also known to play practical jokes on Mako.
Mako (Chinese: 馬高 pinyin: Mǎ Gāo) is a firebender from a multicultural family who grew up on the streets of Republic City as an orphan with his younger brother, Bolin. Mako always wore his signature red scarf that was once his father's, who was murdered along with his mother when he was a boy. He formed a pro-bending team with his brother and Hasook and aspired for his new career to bring him fame and fortune. His aspirations changed, however, when he met Avatar Korra, who joined the team to replace Hasook and became a loyal friend. Mako, with the help of his teammates, was able to lead the team to second place in the championship. After the tournament's conclusion, Mako joined Korra in her efforts to stop the Equalists. Although Mako had feelings for Korra, both of them decided that it would be best to stay friends.
In the following months, Mako joined the Republic City Police Force, where he steadily rose up from being a beat cop to a detective. He joined his friends in an effort to stop Unalaq and Vaatu from merging. A few weeks after Harmonic Convergence, he rejoined Team Avatar in their search for new airbenders. However, they stopped when the Red Lotus attempted to kidnap Korra in Zaofu, instead working to bring down the anarchist organization.
After taking down the Red Lotus, Mako returned to his work as a police officer and was later appointed as Prince Wu's bodyguard, a position he continued in after the latter's coronation as Earth King.
Tenzin (Chinese: 丹增 pinyin: dān zēng) is the youngest child of Avatar Aang and Katara and the oldest living airbending master. He lives on Air Temple Island with the Air Acolytes, his wife Pema, and their four children: Jinora, Ikki, Meelo, and Rohan. During the resurfacing of airbending across the Earth Kingdom after the Harmonic Convergence of 171 AG, Tenzin and his family temporarily relocated to the Northern Air Temple. A calm and serious man, he represented the Air Nation on the United Republic Council in Republic City prior to its dissolution and was responsible for educating Avatar Korra in the art of airbending and spirituality.
Lin Beifong (Chinese: 北方琳 pinyin: běifāng lín) is the Chief of Police of the Republic City Police Department, the daughter of Toph Beifong and Kanto, and the older half sister of Suyin Beifong. Although her mother taught Avatar Korra's previous incarnation how to earthbend, Lin displayed no affection toward her when they first met. However, Lin's feelings toward the young Avatar changed when Amon and his Equalists made their public appearance and openly challenged the benders of the world. Lin is brave, loyal, and willing to sacrifice herself in order to do what she believes is right.
Zaheer is the leader of the Red Lotus, a martial arts expert, and an anarchist, who strongly believes in the foundation of a new world without the Order of the White Lotus, the four nations, or the Avatar. After the Harmonic Convergence of 171 AG, he also became an airbender and, after having let go of his final earthly tether, he unlocked the ability of flight, becoming the second person ever to have done so.
In pursuit of his goals, Zaheer and three of his comrades were captured and imprisoned. After becoming an airbender thirteen years later, he escaped the custody of the Order of the White Lotus and subsequently freed his allies from prison. He threw the Earth Kingdom into chaos by assassinating the Earth Queen and attempted to end the Avatar Cycle by killing Avatar Korra while she was in the Avatar State, though failed, leaving him as the only survivor of their group of four
Following his defeat, Zaheer was once again imprisoned. To his disappointment, he heard of Kuvira placing the people of the Earth Kingdom under her military dictatorship, thus rendering his attempt to free them from oppression futile. Because of this, Zaheer helped Korra in 174 AG to meditate into the Spirit World and let go of her fear of him and of "what might have been". Under the pretense of "the enemy of my enemy is my friend", he hoped that by aiding Korra, she could stop Kuvira.
General Kuvira (Chinese: 古維拉 pinyin: Gǔ Wéi Lā) is a master earthbender and metalbender who was part of the Metal Clan in Zaofu. Prior to her departure in 171 AG, Kuvira served as both the captain of the city's guard and part of Suyin Beifong's dance troupe. Following the outbreak of anarchy in the Earth Kingdom, Kuvira earned the trust of the world leaders by stabilizing Ba Sing Se and was appointed as the nation's provisional leader. She subsequently set out to reunite the rest of the kingdom with her army, which earned her the title of "Great Uniter". In her pursuit of order, Kuvira offered to protect the nation's states from bandits in exchange for their loyalty. During Prince Wu's coronation, Kuvira denounced the authority of the Earth King and dissolved the Earth Kingdom in favor of an "Earth Empire" under her leadership. Her reign came to an end, however, after she was defeated in Republic City and imprisoned. She was also engaged to Baatar Jr., who left Zaofu with her to support her ideals, though ended their relationship when she was willing to sacrifice him to have a chance to end Avatar Korra's life.
Recurring characters and organizations
The Avatar-cycle follows the cycles of the seasonal order of Earth's climate, as each element represents a season: Spring (Earth); Summer (Fire); Autumn (Air); Winter (Water). In Aang's case, he was an Air Nomad, thus Korra (his immediate reincarnation) was born as a Water-bender.
Avatar: The Last Airbender
- Avatar Roku (voiced by James Garrett and by Andrew Caldwell (in the younger days)) is Aang's immediate past life, a Fire-bender Avatar, serving as his spiritual advisor. In Book Three, it is revealed that Roku's aiding Aang is motivated by his guilt over failing to stop his childhood friend Sozin (who he happened to share a birthday with), later the Fire Lord of Roku's time, from his campaign of war. Roku is also the grandfather of Azula and Zuko's mother Ursa. In the live-action film, Roku's role as Aang's guide is assumed by the Dragon Spirit (John Noble).
- Fang was Avatar Roku's dragon-animal guide. His spirit, with help from Hei Bai, guided Aang to Roku's Island and helped Aang achieve a connection with Roku. Fang died protecting Roku from a Pyroclastic flow caused by the eruption of the Volcano on Roku's Island.
- Avatar Kyoshi (Japanese: きょし)(voiced by Jennifer Hale) was the Earth-bender Avatar preceding Roku, 412 years before the start of the series. Being straightforward and often cold in personality, Kyoshi is described as a gigantic woman, possessing the largest feet of any Avatar, and lived to be 230 years old. Her traditional weapons are golden metal fans which, with her attire and fighting style, were adopted by the Kyoshi Warriors of Kyoshi Island, which she detached from the mainland to defy a self-stimulated conqueror. Kyoshi was also responsible for the establishment of the Dai Li.
- Avatar Kuruk (voiced by Jim Meskimen) preceded Kyoshi. He was the Water-bender Avatar before Korra. A self-described "go-with-the-flow" personality, he lived in a time of relative peace and stability. Kuruk later suffered for being inattentive when the spirit Koh the Face Stealer stole the face of his true love. Kuruk spent the rest of his life hunting down Koh, but failed to take revenge.
- Avatar Yangchen (Chinese: 揚塵 pinyin: yáng chén) (voiced by Tress MacNeille) was the Air Nomad Avatar before Aang. Unlike the other Avatars, who advised Aang to end the Fire Lord's threat to world peace without hesitation, Yangchen understood Aang's reluctance to kill Firelord Ozai due to the Air Nomad culture of pacifism. However, she still reminded Aang that the Avatar's priority is to the world, rather than spiritual enlightenment.
The Legend of Korra
- Avatar Wan (Chinese: 萬 pinyin: wàn) (voiced by Steven Yeun) was revealed in the sequel series Legend of Korra to be the very first Avatar at a time when spirits could freely enter the physical world. His name is a play on the English written numerical word one (i.e. 1); that is, Avatar Wan was literally Avatar One, or the first (1st) Avatar.
- Originally a forebear from the tribe later known as the Fire Nation, Wan became an outcast when he obtained fire bending under false reasons from a Lion Turtle. This led Wan to live among the spirits, traveling among them before he unknowingly freed the dark spirit Vaatu from the hold of his benign counterpart, Raava. Accompanying Raava to help set things right, the spirit serving a means to exchange one form of bending for another, Wan obtains the ability to bend the other elements from the other Lion Turtles. But during the fight with Vaatu as the Harmonic Convergence begins, he could only bend all four elements as long as Raava was inside his body. Wan's soul permanently merged with Raava through the Convergence's energies. After imprisoning Vaatu and having most of the spirits return to their world, Wan sealed the Spirit Portals in hopes that no one from his world would free Vaatu. Wan spent his remaining days attempting to keep the people from waging war on each other. Though he eventually died in regret during a battle, Raava's presence allowed him to be reincarnated indefinitely. Wan's death began the Avatar cycle.
Spirit World Denizens
Avatar: The Last Airbender
- Tui (Chinese: 推 pinyin: tuī) and La (Chinese: 拉 pinyin: lā) are respectively the Moon (Tui) and Ocean (La) Spirits who traveled to in the physical world and remained there. The two spirits assumed the form of koi that occupied the Spirit Oasis within the Northern Water Tribe's capital city. The two spirits play an important role in waterbending, information that Admiral Zhao learned and used to kill Tui to permanently remove waterbending. However, empowered by Aang in his Avatar State, La assumed its true form to drive off the Fire Nation invasion force before learning that Tui is revived by Yue's sacrifice. On its way back to the Spirit Oasis, finding the man who murdered Tui, La dragged Zhao into the depths. It would be later revealed in the Legend of Korra that La disposed of Zhao in the Spirit World's Fog of Lost Souls. The push and pull swimming motion of Tui and La, in their koi forms, resemble the Chinese philosophical symbol of Yin and Yang. Their resemblance to the symbol is more than coincidental, as the two spirits embody the symbol's meaning.
- Koh the Face Stealer (voiced by Erik Todd Dellums) is an ancient Spirit who steals the faces of his victims unless they are expressionless. One of Koh's earliest victims was the beloved of Avatar Kuruk as a means to put the Avatar in his place for letting his guard down during peace time. During his time at the Northern Water Tribe, Aang met with Koh as he knew the identities of the Moon and Ocean spirits. In Avatar: The Last Airbender – The Search, it is revealed that Koh is the estranged son of the Mother of Faces, who can restore her son's victims to normal or alter their appearance.
- Wan Shi Tong (Chinese: 萬事通 pinyin: wàn shì tōng) (voiced by Héctor Elizondo) is a powerful owl-like Spirit, who claims to know ''ten thousand things'', who brought his library into the physical world, its content provided by his knowledge-seeking foxes, to help people better themselves through his collection. However, as a result of Zhao learning of the Ocean and Moon Spirits, Wan Shi Tong became disillusioned with humans for using his knowledge in their conflict. After Aang and his friends lie to acquire information on the Day of the Black Sun, despite their just reasons, Wan Shi Tong takes his library back to the Spirit World with humans no longer allowed, with the exception of a Ba Sing Se Professor named Zei who decided to live in the library. In the sequel series, Wan Shi Tong becomes an ally to the season two antagonist Unalaq and played a role in the abduction of Aang's granddaughter Jinora.
- Hei Bai is a black and white forest spirit that sometimes takes the form of a docile Giant panda, but can also change into a vicious giant four-armed spirit-monster when enraged. He is the protector of the Earth Kingdom's forests. He was first seen terrorizing the Senlin Village and blaming the occupants for the destruction of his nearby forest, not knowing it was caused by the Fire Nation. When Aang eventually calmed him down, he helped Aang make a connection to Avatar Roku's spirit and showed him a vision of Sozin's Comet. He is last seen guiding Avatar Aang out of the Spirit World when Aang was at the Northern Water Tribe.
- Lion Turtles (voiced by Jim Cummings) are gigantic lion-and-turtle hybrid creatures. They are the source-vessel of the Elemental Bending that is present throughout the series. Each Lion Turtle represents a specific element, and thus can only give bending related to that element. They are viewed as deities, and are thus the supreme authority of the Four Nations. Before the establishment of the Four Nations, they served as Lion-Turtle Cities, with an entire city on the back of their shells. Using Raava The Light Spirit, they granted Avatar Wan the ability to bend all four elements. It is unknown exactly what happened to them after they decided to leave the world in Wan's protection, only that one decided to remain and grant Avatar Aang spiritual bending.
The Legend of Korra
- Raava and Vaatu (voiced by April Stewart and Jonathan Adams respectively) are respectively the primal spirits of harmony, peace and light; and of chaos, strife and darkness. Raava and Vaatu's battle was a visual reference to the Chinese Yin Yang symbol, a similar reference was made in the original series with the Ocean and Moon spirits' koi form (see below). Raava is fused with Wan to become the Avatar Spirit. She is one of the oldest known spirits, having existed over ten thousand lifetimes before the appearance of the first humans. She and Vaatu, spent much of their existence combating each other, at least since the Harmonic Convergence in 19,829 BG, with neither able to fully vanquish the other. Even if Raava were to destroy Vaatu and usher in a new era of peace, what little darkness existed in Raava would magnify until Vaatu was reborn and burst forth, beginning the cycle again. The reverse would happen to Vaatu if he were victorious over Raava. The era of Raava encompasses the time period prior to the beginning of the Avatar Cycle around 9,829 BG, when Wan became the first Avatar. During the Harmonic Convergence in 9,829 BG, Raava permanently merged her essence with Wan's, creating The Avatar Spirit. After her demise in 171 AG, Raava lost her connection to Wan and all the Avatars after him, but was able to merge again with Korra, recreating the Avatar and starting the Avatar Cycle anew.
- Aye-aye Spirit (voiced by Jason Marsden) is a guardian of the Spirit Oasis that Avatar Wan first stumbled upon after his banishment into the Spirit Wilds. Though refusing to let him in at first, the Spirit developed a bond with Wan, whom he nicknamed ''Stinky'', and allowed Wan to live among them and teach him about spirits.
United Republic of Nations
The Legend of Korra
- President Raiko (voiced by Spencer Garrett) is a nonbender native to Republic City and the first democratically-chosen president of the United Republic of Nations. An assertive authority figure, he was elected to the position following the dissolution of the United Republic Council in 171 AG.
- General Iroh II (voiced by Dante Basco) is the youngest general in United Forces history and the commander of the navy's First Division. He is the son of Fire Lord Izumi, the grandson of Lord Zuko, and named after his grandfather's uncle. A firebending master and skilled military leader, Iroh played a crucial role in the battle for Republic City in 170 AG, in which he fought on despite losing his fleet.
- Sir Iknik Blackstone Varrick (voiced by John Michael Higgins) is an eccentric and charismatic nonbending billionaire businessman known for his ambitious nature and flamboyant fashion style. Born in the Southern Water Tribe, he is a nobleman who enjoys gallivanting across the globe on his yacht and flaunting his extravagant lifestyle, often at the expense of his assistant, Zhu Li. A man who respects directness, he struck up a close friendship with the honest and candid earthbender Bolin. He later masterminded a civil war between the Northern and Southern Water Tribes, claiming that Unalaq's occupation of his country was a threat to the South's wealth, especially his own, while furthering his true intention of profiting off of the escalating conflict. However, his attempt to also draw the United Republic into the war led to his arrest. Nevertheless, Varrick soon managed to escape, and settled down in Zaofu as the head of the city's technology department, though he later accompanied Kuvira on her quest to reunite the Earth Kingdom. Unwilling to weaponize spirit energy for her, Varrick eventually deserted her army in 174 AG and helped Team Avatar to stop her from conquering Republic City. After Kuvira was defeated, Varrick married Zhu Li. His full name was only revealed at his wedding to Zhu Li in the finale of the series.
- Zhu Li Moon (voiced by Stephanie Sheh) is Varrick's personal assistant who performs any task he requires the instant he requires it. She speaks when spoken to and stays in the background whenever possible. Her staunch loyalty to Varrick inspired him to name both his personal battleship and his mathematical weight calculations after her. Zhu Li's dedication was truly tested in a fight with Kuvira's army that they lost while trying to flee to warn Republic City of her motives. When handed down a sentence of confinement to a re-education camp, she turned on Varrick to avoid punishment and pledged herself to Kuvira from then on. After Varrick is assumed dead, Bataar Jr. takes over his research on the spirit vine energy with Zhu Li serving as his assistant. It's all a ploy by her to get close enough to destroy the weapon upon its completion, but she's found out and nearly killed when Bolin and Opal come to rescue her. Upon her reunion with Varrick in Republic City, she finally spoke out loud about the way he's always treated her, insisting on her role as his assistant be upgraded to equal partner should they continue to work together.

She is an exceptionally skilled fighter and Sokka's current girlfriend. She and the Kyoshi Warriors encountered and fought Azula in Book Two to which they were defeated and imprisoned but Suki was liberated by Sokka and Zuko in Book Three, and remained with the protagonists thereafter and joined Toph and Sokka to disable the Fire Nation's air force.

Upon learning of the war, the king joined forces with the Avatar and arrested his chancellor. Afterwards, he left to travel the world with his pet bear Bosco (which happens to be the only non-hybridized real animal in the series) before resuming the throne sometime after the series ended. In Legend of Korra, Kuei ceded the land that the United Republic was built on.
- Haru (voiced by Michael Dow) is an Earthbender that Sokka, Aang, and Katara meet in Book One, and whom they assist freeing his father and other Earthbenders from the Fire Nation.

- The Mechanist (voiced by Rene Auberjonois) is a brilliant and eccentric inventor in the Earth Kingdom, who led his people to take up residence in the abandoned Northern Air Temple when their village was destroyed by a flood. Unfortunately, his abilities come to the attention of the Fire Nation and he is coerced into developing a number of machines, redeeming himself after he breaks the arrangement and helps Aang repel the Fire Nation when they raid the temple. Because of his scientific approach to the world, he becomes friends with Sokka, and they develop a number of devices together. He later aids the invasion on the Day of the Black Sun with numerous new inventions, including waterbending-powered submarines. When the invasion fails, he is captured and later reunited with his son Teo after the war.
- Teo (voiced by Daniel Samonas) is the Mechanist's son, rendered paraplegic and wheelchair-bound by a flood. A kind-hearted, respectful, and honest boy, he soon becomes friends with Aang. After discovering that his father has been reluctantly creating machines for the Fire Nation, Teo aids Aang repelling Fire Nation raiders. He returns during the invasion of the Day of the Black Sun, but is forced to separate from his father when the Avatar's group is forced to surrender. He accompanies Aang to the Western Air Temple and befriends Haru and the Duke before the Avatar's group is forced to flee when Azula attacks the temple. He is reunited with his father after the war.
- Long Feng (Chinese: 龍鳳 pinyin: lóng fèng) (voiced by Clancy Brown) is the intelligent Grand Secretariat of Ba Sing Se and chancellor to the Earth King, making him the power behind the throne. As leader of the Dai Li, Long Feng uses propaganda to conceal the Hundred Year War while silencing anyone who disrupts the order. Once exposed, Long Feng allies himself with Azula in a scheme to use her to pull a coup on the Earth King, only to find his men are more willing to follow Azula's commands than his.
- Joo Dee (Chinese: 朱蒂 pinyin: zhū dì) (voiced by Lauren Tom) is a woman in Ba Sing Se, who appears as the protagonists' hostess but later turns out to be one of many female agents that the Dai Li brainwash into obedient servants. Joo Dee shows little emotion at all. Despite seeming brainwashed, she understands the city's situation.
- Xin Fu (Chinese: 辛賦 pinyin: xīn fù)(voiced by Marc Graue) was a promoter and host of an earthbending prizefighting ring who later becomes a bounty hunter, hired by Toph's father to bring her home. He works with Earthbending instructor turned bounty hunter Master Yu to accomplish this. While searching for Toph, he also briefly pursues Zuko and Iroh. He succeeds in capturing Toph in a metal box, but she manages to escape by creating Metalbending and proceeds to seal him and Master Yu inside. Neither is shown again.
- Master Yu is an instructor at an Earth-bending academy, as well as Toph Beifong's personal Earth-bending teacher. At first, he was unaware of Toph's prowess, considering that he saw her as blind and helpless. Later he, along with Xin Fu, is contracted by Toph's father as bounty hunters to bring her home.
- The Boulder (voiced by Mick Foley) is an earthbender first seen as a prizefighter in Book Two; but who re-appears in Book Three during the attempt to invade the Fire Nation. He speaks of himself in the third person and his name is thought a parody of The Rock.
- Big Bad Hippo (voiced by Kevin Michael Richardson) is an opponent of Boulder's in an Earthbending match in Book Two, and later appears with him in the invasion in Book Three. He is a tall, heavy man with 4 especially-prominent teeth, and is possibly a parody of King Hippo of the Punch-Out!! franchise.
- Aunt Wu (voiced by Tsai Chin) was an elderly citizen of Makapu Village who worked as a fortuneteller. The people of Makapu were so confident in her abilities that they abandoned going up the nearby volcano's crater to check if it would erupt, instead relying on Aunt Wu's predictions. Well-regarded for her free and accurate readings, every prediction she made was taken as gospel by the village at large, as well as Aang and Katara. Her methods of divination ran from palmistry to oracle bones and cloud reading. She was helped in her hut by her assistant, Meng. Though Sokka was heavily skeptical of her ''fortunetelling'', he indirectly helped her prediction become a reality, such as when he helped convince Wu of her false prediction when Aang redirected the clouds to alert the town to a volcanic eruption, which happened at that instant. Aang prevented the lava from destroying the town by redirecting the flow, cementing Wu's prediction as a reality, as her exact words were: ''The Town will NOT be destroyed by the volcano this year.''
- Blind Badgermoles are revealed to be the original Earth-benders. They are giant wild creatures that burrow tunnels underground using Earth-bending. It is unknown exactly how many of them are there, though 2 Badger-Moles have made recurring appearances throughout the series. They found a helpless young blind Toph crying and wandering the caves one night. Though they are aggressive wild creatures, they felt an immediate bond towards Toph because of their shared disability with her, and they immediately took her under their tutelage and taught her how to use Earth-bending as a means of sight.
- Oma and Shu are the first humans to be taught earth-bending by the Badgermoles. The lovers created a maze of tunnels underneath the mountains that divided their feuding villages, in order to secretly meet up. Shu was killed in the war between their villages, and from her grief, Oma displayed her potent earth-bending powers, but instead of destroying the two villages, she declared the war between them over and together they build a city where they could coexist. The city was named Omashu.

- Earth Queen Taini Hou-Ting (voiced by Jayne Taini), was the 53rd Hou-Ting Dynasty-sovereign of the Earth Kingdom, is the daughter of Earth King Kuei. Hou-Ting concerned herself personal vices at the expense of her people's welfare, she even claimed to have eaten her father's bear Bosco. Her reign was marked by revisionist, conservative, and absolutist politics; with the Dai Li secret police eliminating dissidents without trial. In an effort to capitalize on the changes brought on by Harmonic Convergence, Hou-Ting ordered the capture of Ba Sing Se's new airbenders and conscripted them into her army, training them in a base underneath her temple. When this was discovered, Korra freed the airbenders. She was assassinated in 171 AG by Zaheer during the insurrection of the Red Lotus, resulting in the collapse of the Earth Kingdom.
- Prince Wu Hou-Ting (voiced by Sunil Malhotra), the 54th Hou-Ting Dynasty-sovereign of the Earth Kingdom, a great-grandson of Earth King Kuei.

As the last sovereign of the Hou-Ting Dynasty, his reign abolished monarchy in favor of a republic of sovereign states, governed by a constitution, with democratically elected representatives.
Avatar: The Last Airbender
- Fire Lord Ozai (voiced by Mark Hamill in the animated series, and portrayed by Cliff Curtis in the live-action film) is the ruler of the Fire Nation and is the chief antagonist of the series. He is often depicted as unnecessarily cruel, such as scarring Zuko's face and banishing him for perceived disrespect. Ozai shows Azula favor, but only due to her skill as a prodigy and being an embodiment of his ideals rather than any genuine love. Having welcomed his son home after Azula lied to him that Zuko killed Aang, Ozai is furious to learn of the Avatar's survival. When Sozin's Comet draws near, Ozai renames himself 'Phoenix King' and embarks to destroy the Earth Kingdom, entrusting an unstable Azula with their homeland. Defeated by Aang, Ozai is stripped of his ability to firebend and imprisoned.
- Fire Lord Sozin (voiced by Ron Perlman (as an old man) and Lex Lang (as a young man)) was the Fire Lord who started the war with the other nations. In a flashback, it is shown that he was once friends with Avatar Roku, who happened to share a birthday with him, but disobeyed his edict against war and later permitted his death. With the Avatar no longer there to maintain balance, Sozin wiped out the Air Nomads using the power of a nearby comet, renamed Sozin's Comet in his honour. It is hinted that, in his last moments before death, Sozin regretted his actions.
- Mai (voiced by Cricket Leigh) is an impassive, bored, stoic young noblewoman who, along with Ty Lee, is a friend and accomplice of Azula. She is the elder child of the Governor of New Ozai (previously Omashu, then renamed Omashu again). Her primary weapons are throwing knives, darts, and shuriken concealed in her clothing. Mai eventually become's Zuko's girlfriend, although he leaves her to join Aang and Team Avatar. She later visits him when he is incarcerated in Boiling Rock prison; upon his escape, Mai shocks everyone by holding off the guards and dueling Azula herself, explaining that her love for Zuko is stronger than her fear of Azula. She is released after Azula's defeat, and reunites with Zuko. However, in Avatar: The Last Airbender - The Promise, she breaks up with Zuko after learning that he has been visiting his imprisoned father without telling her. She later was involved in Avatar: The Last Airbender - Smoke and Shadow, in which she joins forces with Zuko and Aang to deal with the threat of the Kemurikage Spirits and the reactionary New Ozai Society led by her estranged father.
- Ty Lee (voiced by Olivia Hack) is cheerful, energetic, and somewhat of a valley girl who, along with Mai, accompanies her childhood friend Azula on her quest. She is one of seven sisters and joined the circus at an early age to appear "different from a matching set". She is a peerless acrobat and can paralyze people or temporarily neutralize their bending powers by striking pressure points in a similar fashion to the martial art style of Dim Mak. In Book Three, she was temporarily imprisoned after she supported Mai against Azula, and released when the Fire Lord was defeated. She later joined the Kyoshi Warriors (contradictory to her earlier statement of not wanting to be part of a matching set), whom she had earlier impersonated in Book Two. Ty Lee's chi-blocking techniques were used for nefarious purposes in the sequel series, although it is not clear if there is a direct connection.
- Admiral Zhao (formerly Commander Zhao) (Chinese: 趙 pinyin: zhào) (voiced by Jason Isaacs in the animated series, and portrayed by Aasif Mandvi in the live-action film) is an antagonist of Book One who is a hot-tempered Fire Nation admiral in pursuit of the Avatar, and Zuko's principal rival throughout the first season. The rivalry is shown throughout various episodes, including an Agni Kai, various banters involving mass gloating, and even attempting to kill off Zuko for interference in his capture of Aang. He also plans to kill the world's 'Moon Spirit' and thus destroy the waterbending capability of the Northern Water Tribe, in which he fails when Princess Yue becomes the new Moon Spirit to replace the original. Zhao is then dragged into the depths by the vengeful Ocean Spirit. In the sequel series The Legend of Korra, it is revealed that Zhao's spirit was placed in the Fog of Lost Souls, where he became a victim of madness by the time he is encountered by Aang's children, mistaking Tenzin for his father.
- Princess Ursa (voiced by Jen Cohn) is the mother of Zuko and Azula and the former wife of Fire Lord Ozai, later revealed to be the granddaughter of Avatar Roku. While she made few appearances in the series, Ursa's story is expanded in the sequel comics. As revealed in Avatar: The Last Airbender – The Search, Ursa was in love with an actor named Ikem before she is forced to end their relationship while betrothed to Ozai. Though told that she is to abandon her old life, expecting Ozai to have been intercepting her mail, Ursa secretly wrote letters that included a false letter claiming Zuko was Ikem's child. The false letter caused the rift between Ozai and Zuko, the former claiming to have arranged Ikem's death after the actor mysteriously vanished. When Ursa learned that Ozai was ordered by his father to kill Zuko, she becomes a means for Ozai to have his father murdered before banishing her in exchange for Zuko's life. As revealed in The Search, to forget her time with Ozai and ensure her children's protection, Ursa had the spirit known as the Mother of Faces change her face and alter her memories. Now going by name of Noriko, Ursa married Ikem, who also had his face changed with the name of Noren, and they have a daughter named Kiyi. Zuko finds her years later and despite Azula's attempt on her life, Ursa is welcomed back into her son's life as she is restored to her original self.
- Fire Lord Azulon (voiced by Walker Edmiston) was Sozin's son and Ozai & Iroh's father, and thus Zuko, Azula & Lu Ten's paternal grandfather. He was killed by Ozai in an attempt to revoke Iroh's birthright (as a first-born) after he believed Iroh to be unsuitable for the position considering he lost his son Lu Ten and has no heirs apparent. Upon hearing his conditions for the revoking of the birthright (a son for a son), Princess Ursa interfered and voluntarily poisoned him and offered herself for banishment in order to protect her son Zuko. It was revealed that his granddaughter Azula, and the Gates of the Fire Nation's harbor were named after him. During a flashback of his funeral service, it was mentioned that he was a widower as his wife Ilah (never seen in the series) died before him.
- Prince Lu Ten (deceased 5 years before the events of the main storyline) was the only son, and heir apparent of General Iroh, thus Azula and Zuko's cousin. His death at the Siege of Ba Sing Se, lead to Ozai's decision to usurp Iroh as heir to the throne of the Fire Nation. Iroh was shown still mourning his death in the season 2 episode ''Tales of Ba Sing Se'' short entitled ''The Tale of Iroh''.
- Fire Sages are a group of elite Fire Nation religious guardians of the Avatar monuments. They are the founders of the Fire Nation, and the leader of the Sages was known as a Fire Lord. However, over the years, the Fire Nation became a monarchy and the title of Fire Lord was reserved for the head of state, thus the beginning of the Fire Nation Royal bloodline. The Sages distanced themselves from the Royal family and began serving the Avatar, but over the hundred years, some of them have soured towards the Avatar for abandoning them and thus started serving the Fire Nation Royal Family again. They alerted Fire Lord Ozai to Avatar Aang's existence when Aang entered the Avatar-state for the first time. The Sages are also the de facto religious authority for the Fire Nation's Royal wedding-, funeral- and coronation ceremonies, as well as identifying the newest Avatar born from the Fire Nation.
- Ran and Shaw are two colossal red & blue dragons known as the Fire Bending Masters, and they are the last-known live-dragons at the time. As dragons, they are the source of all fire-bending. Iroh faced their judgement and received their teaching and in return, he kept their existence secret from everyone, even going so far as to lie about killing them and adopting the title ''Dragon of The West''. Both Zuko and Aang faced their judgement and received their teachings.
- General Shinu (formerly Colonel Shinu)(Chinese: 使弩 pinyin: Shǐnǔ) first appeared as the officer commanding the Yuyan Archers, an elite archer squad. He was later promoted to General, and reported at the Fire Lord's war meeting the day before the eclipse.

She is later seen again discussing actions against Kuvira's Empire, refusing to let her Nation get involved in another war, but agreeing to aid when needed.
Avatar: The Last Airbender
- Admiral Hakoda (voiced by André Sogliuzzo) is Katara's and Sokka's father and the leader of the Southern Water Tribe. Much of Sokka's ingenuity in the show is attributed to Hakoda's teachings. Hakoda went to fight the Fire Nation before the beginning of the series, reappearing later to lead his son's invasion in Book Three.
- Princess Yue (Chinese: 月 pinyin: yuè) (voiced by Johanna Braddy in the animated series, and portrayed by Seychelle Gabriel in the live-action film) is the daughter of Chief Arnook of the Northern Water Tribe. When Yue nearly died at birth, her father invoked the Moon Spirit to give her life. In Book One, she appears as a sixteen-year-old girl engaged to marry warrior Hahn; but becomes enamoured of Sokka. When the Moon Spirit is killed by Admiral Zhao, Yue gives up mortal existence to become the new Moon Spirit, in which role she re-appears occasionally in Books Two and Three, including a brief representation in the Ember Island Players episode. The word Yue (月) means "moon" in Mandarin Chinese.
- Kya (voiced by Grey DeLisle) was Sokka & Katara's mother in The Last Airbender. She gave herself up in order to protect her tribe's last water-bender of the time, her daughter Katara. She was presumably killed by her Fire Navy captors known as the Southern Raiders.

- Kanna (voiced by Melendy Britt; portrayed by Katharine Houghton in the live-action film) is Sokka and Katara's paternal grandmother, informally referred to as Gran-Gran. She encouraged them to help Aang on his journey as the Avatar.
- Hama (voiced by Tress MacNeille) was an elderly woman living in the Fire Nation. She was an Inn-keeper who offered a place to stay to Team Avatar after finding them camping in the woods. She later revealed that she was, at that time, the last Water Bender from the Southern Water Tribe, and a childhood friend of Kana (Katara and Sokka's Grandmother) before she was taken prisoner by the Fire Nation. She managed to escape prison by developing a technique called ''Bloodbending'' (water is a prevailing substance in blood), which works in a similar fashion to Puppetry. By controlling the water within the blood of a body, she could forcefully manipulate its movements. She held a grudge against the Fire Nation soldiers who imprisoned her, and thus ''possessed'' and captured Fire Nation citizen who went near the mountain during a full moon. She tricked Katara into learning the technique so that it could be passed on to others, though Katara used it against Hama herself to stop her from controlling Aang and Sokka. The bloodbending technique was eventually deemed illegal by the time of the Korra series, though a Water Tribe criminal named Yakone managed to learn of its existence and used it to criminal ends, later training his two sons, Tarrlok and Noatok (aka Amon), in the technique as well.

He moved to the Southern Water Tribe, where he became the tribe's unofficial leader and married Senna, with whom he has one daughter, Korra. For many years, Tonraq lived in peace with his family, but when the tensions between the Northern and Southern Tribe escalated into open civil war, he discovered Unalaq's secret scheme that had caused his banishment. After this revelation, he took on the leadership of the Southern Water Tribe rebels in order to fight his younger brother and the Northern army. After Unalaq's death, the South gained independence from the North and the Council of Elders officially appointed Tonraq as the first Southern chief.

Eska eventually selects an un-reciprocating Bolin as her fiance, but is visibly upset when he rejects her proposal and breaks up with her. In season 3, they are revealed to have succeeded their father, Chief Unalaq, as co-Chieftains of the Northern Tribe.
Before the genocide, airbenders were a diverse and migratory people united by the Five Air Temples. The Five Air Temples were self-governed by a unitary pseudo-ecclesiastical adhocratic senate, known as the Councils of Elders. Composed of wise airbending masters, they had limited authority in their respective temples; they served as counsel for its citizens and airbending instructors. Except for Air Temple Island, sex segregation was par norm; the Northern and Southern Air Temple branches were exclusively male, while the Eastern and Western Air Temple branches were exclusively female.
After the genocide, to preserve the culture of the extinct Air Nomads, Avatar Aang founded the Air Acolytes; the group primarily consisted of Earth Kingdom non-benders that would uphold Air Nomad philosophies and traditions. After the acolytes' formation, the air temples were each administered by abbots and abbesses. Following harmonic convergence-event of 171 AG, Tenzin, by virtue of being the world's most senior airbending master, continued to have a say in global affairs as the figurehead of the Air Nation. He continued to reside on Air Temple Island branch.
Avatar: The Last Airbender
- Monk Gyatso (voiced by Sab Shimono (as an old man) and Sean Marquette (as a young man)) was a member of the Council of Elders at the Southern Air Temple that was killed by Firebenders 100 years prior to the show. In Book One, he is depicted as Aang's guardian and surrogate father, and is noted for his kindness and sense of humor. In Book Two, he is seen in Aang's dream sequence. In Book Three, he is also revealed to have a strong friendship with Roku, leading to the observation that some friendships are strong enough to transcend lifetimes.

After Earth Queen Hou-Ting's murder and subsequent stabilization of the Earth Kingdom, he left Zaofu together with Kuvira to reunite the nation.
- Baatar Beifong is an architect and the husband of Suyin Beifong, with whom he has five children. He helped create the metal city of Zaofu.
- Wei and Wing Beifong are the twin sons of Suyin and Baatar. The youngest of their siblings, they invented a game for metalbenders called power disc.

The White Lotus
Avatar: The Last Airbender
The White Lotus is an international organization of teachers, philosophers, and warriors, who value knowledge and wisdom above nationality. Their name comes from the White Lotus tile, a low-ranking piece in the game of Pai Sho, which is the most common form of communication among members. Iroh is among the highest-ranking members, and hints of the Order are dropped throughout the series through his actions. Iroh, a Grand Lotus, eventually calls the entirety of the Order to reveal themselves and liberate Ba Sing Se during the events of Sozin's Comet: The Final Battle.
In The Legend of Korra, the White Lotus has expanded to act as an elite international police force among the Five Nations, while also taking responsibility for finding, guiding and defending the next Avatar, a task previously the responsibility of internal sages within each Nation. However, it would cause a division among its ranks with those disillusioned forming the anarchistic Red Lotus.
- King Bumi (voiced by André Sogliuzzo) is the whimsical, elderly King of Omashu, an Earth Kingdom stronghold. As a child, Bumi was a close friend of Aang's. Despite his age and apparent frailty and eccentric personality, Bumi is an Earthbending master, himself claiming to be "the most powerful Earthbender you'll ever see". Putting Aang through a series of tests in Book One, Bumi surrendered to the Fire Nation in Book Two to avert any harm to his people while telling Aang to find another who can teach him Earthbending, stating he should find someone who waits, then listens (describing a then-unfamiliar Toph's fighting style). In Book Three, Bumi breaks free during the Day of Black Sun and single-handedly retakes Omashu before answering Iroh's call to liberate Ba Sing Se. The word Bumi comes from the Sanskrit 'bhūmi' meaning 'earth'. In the sequel series, Aang and Katara named their first born son after King Bumi.
- Master Pakku (voiced by Victor Brandt) is a Waterbending master and instructor of the North Pole's Northern Water Tribe Waterbending classes. He is dryly sarcastic and very serious about his teachings. He insists on only teaching male students, but relents after identifying Katara as the granddaughter of his runaway fiancée Kanna. At the climax of Book Three, Pakku joins the rest of the order in liberating Ba Sing Se, and reveals that he has married Kanna.
- Jeong Jeong (voiced by Keone Young) is a former admiral of the Fire Nation's navy who lives in exile with his followers. Though he had once been Zhao's teacher, Zhao quit because he believed Jeong Jeong's teaching methods ineffective. Even though he warned against it, Jeong Jeong taught Aang the basics of Firebending by using a flame and a leaf, although Aang eventually relented and realize he needed to follow the proper elemental cycle. As with most of the elder masters encountered by Team Avatar, Jeong Jeong revealed himself as a member of the White Lotus at the gates of Ba Sing Se.
- Master Piandao (voiced by Robert Patrick) is a swordsmith and master of swordsmanship, based in the Fire Nation, who teaches a foundation of his skills to Sokka. Piandao is later revealed to have tutored Zuko in swordplay. He later joins the Order of the White Lotus in liberating Ba Sing Se.
The Red Lotus
The Legend of Korra
The Red Lotus is an anarchist splinter faction of the Order of the White Lotus founded by Xai Bau after the Hundred Year War. Until 171 AG, the organization's existence was completely unknown to the public, and the motives of those who worked for it remained unknown. The Red Lotus' agenda is to have the humans and spirits coexist again and usher in a new world order by dismantling the established nations and their leaders, which they originally planned to do by releasing Vaatu from his prison within the Tree of Time, and later by assassinating world leaders and ending the Avatar Cycle.
The only Red Lotus members who were publicly revealed as such were all powerful, influential individuals: the former Chief Unalaq, the truth-seer Aiwei, and a group of terrorists led by Zaheer. The latter had been incarcerated for thirteen years following a failed attempt to kidnap Avatar Korra. Zaheer managed to escape his imprisonment two weeks after Harmonic Convergence, using airbending abilities he had acquired due to the planet's energy shift and subsequently liberated his three associates. They managed to send the Earth Kingdom into chaos, but failed to murder Korra, resulting in the incarceration of Zaheer and the deaths of his three comrades.
- Unalaq (voiced by Adrian LaTourelle) was a waterbending master, the chief of the Northern and Southern Water Tribes, a former member of the Red Lotus, and the first and only Dark Avatar. He was the younger brother of Tonraq, husband of Malina, with whom he fathered Desna and Eska, and uncle of Avatar Korra. A particularly spiritual man, he briefly served as Korra's spiritual mentor until her discovery of his involvement in her father's banishment, at which point he was absolved as her teacher and shunned. Unbeknownst to anyone, Unalaq was working to release Vaatu from incarceration in the Spirit World, and succeeded in this task before fusing with Vaatu to become the Dark Avatar. To this end, Unalaq nearly destroyed Republic City before being defeated and killed by his niece. Even though his attempt to destroy the Avatar and usher the world into an era of darkness was consequently thwarted, Unalaq succeeded in reuniting humans and spirits and thus changing the world forever
- Aiwei (voiced by Maurice LaMarche) was an earthbender, the former trusted adviser of Zaofu's matriarch, Suyin Beifong, being a very capable "truth seer" (i.e. using echolocation as a lie detector. Because of this ability, he gained much respect in Zaofu, until he was discovered to be a mole for the Red Lotus after they failed to kidnap Avatar Korra. After his escape, Aiwei met Zaheer in the Spirit World, where he was sentenced by the airbender to spend an eternity dwelling inside the Fog of Lost Souls
- Ming-Hua (voiced by Grey DeLisle) was the waterbender ally of Zaheer. Ming-Hua was a member of the Red Lotus who was born without arms but still incredibly skilled in waterbending. Ming-Hua was freed from prison by both Zaheer and Ghazan. Ming-Hua played an integral part in deposing the Earth Queen and attempting to kill Korra. Ming-Hua died of electrocution by Mako.
- Ghazan (voiced by Peter Giles) was the earthbender ally of Zaheer. Ghazan was a member of the Red Lotus with a special subset of bending, lavabending. Ghazan was freed from prison by Zaheer after Zaheer had acquired airbending. Ghazan played an integral part in deposing the Earth Queen and attempting to kill Korra. Ghazan eventually committed suicide when under threat of re-capture.
- P'Li (voiced by Kristy Wu) was the firebender ally and girlfriend of Zaheer. P'Li had the special firebending subset ability of combustion bending, being able to cause mass destruction. This caused some speculation that P'Li could be related to the Fire Nation asassin Zuko hired to kill Aang in the past. P'Li was freed from prison by Zaheer, Ghazan, and Ming-Hua. P'Li supposedly was once a hired assassin of a warlord, but was then rescued from her servitude by Zaheer to join the Red Lotus. P'Li played an integral part in deposing the Earth Queen and attempting to kill Korra. P'Li died due to her head quickly being concealed by a sheet of metal by Suyin Beifong when attempting to combustion bend, leading to her demise in the blast of her own attack.
First encountered in "Jet", this rag-tag group led by the episode's namesake operates in the forests of the Earth Kingdom. The group consists of its leader Jet and his subordinates Pipsqueak, Smellerbee, Longshot, the Duke, and Sneers.
Avatar: The Last Airbender
- Jet (voiced by Crawford Wilson) is a charismatic teen-aged rebel who holds a deep grudge against the Fire Nation. He is the leader of the Freedom Fighters, a group of children antagonizing Fire Nation soldiers even at the expense of innocent lives. He is Katara's first crush. In Book Two, he encounters Zuko who goes by his alternate name, Li. The two bond and Jet convinces Li to join the Freedom Fighters but he denies the offer. In later episodes, Jet openly condemns his previous actions in Ba Sing Se, where he is brainwashed by chancellor Long Feng. He is released from this condition by the protagonists and is later presumably killed during a fight against Long Feng.
- Pipsqueak (voiced by Sterling Young) is the largest and strongest of the Freedom Fighters (despite his name), using a giant log as a weapon during the time of Book One. In Book Three, he joins the invasion against the Fire Nation and is taken captive when it falls. He is seen again at the end of the finale.
- Smellerbee (voiced by Nika Futterman) is a Freedom Fighter. In Book One, she was first seen where she helped Jet destroy a dam. In Book Two, she accompanies Jet and Longshot to Ba Sing Se, but leaves Jet after watching him obsess with trying to prove that Iroh and Zuko are Firebenders. She becomes the new leader of the Freedom Fighters after Jet's death. Due to her Tomboy appearance and behavior, she is constantly mistaken for a boy as a running gag.
- Longshot (voiced by Marc Donato) is a silent member of the Freedom Fighters by the time of Book One. In Book Two, he accompanies Jet and Smellerbee to Ba Sing Se. He only says one line after Jet was fatally injured.
- The Duke (voiced by Mitch Holleman in Book One and Nick Swoboda in Book Three) is the youngest and smallest member of the Freedom Fighters during Book One. He is first mistaken as Pipsqueak due to him riding on Pipsqueak's shoulders when they met Sokka, Katara and Aang. He is later seen in Book Three with Pipsqueak in the Day of Black Sun invasion force, and goes with Aang to the Western Air Temple after the invasion's failure, and is separated from them after Azula's attack. He is also seen hugging Toph at the end of the finale.
Equalists are a group of anti-bending activists that evolved into a full-blown terrorist organization under the leadership from Amon, and weapons supplied by Hiroshi Sato.
The Legend of Korra
- Amon (voiced by Steven Blum) (Chinese: 阿蒙 pinyin: ā méng), born as Noatak, was the charismatic and mysterious leader of an anti-bender revolutionary group known as the Equalists. Their ultimate goal was to introduce equality for all by permanently ridding the world of benders. A nimble, agile, and stealthy fighter, Amon was fearless in facing his opponents, regardless of their powerful bending skills and abilities. Claiming to be an innocent nonbender to whom the spirits granted the ability to remove a person's bending permanently, a power previously demonstrated only by the Avatar, Amon gained the confidence and support of many people with the same ideals. However, when the complete conquest of Republic City by the Equalists became imminent, Amon's true identity was exposed to the public by Avatar Korra. In actuality, he was a prodigious Northern Water Tribe bloodbender, son of the escaped crime boss, Yakone. Alongside his younger brother, the former councilman, Tarrlok, Amon was unknowingly shaped by Yakone to be a tool for his revenge against the Avatar.
- Hiroshi Sato (Japanese: 佐藤 博史 さとう ひろし）(voiced by Daniel Dae Kim) was a nonbending industrialist and the founder of Future Industries, whose family lineage extends back to the first Fire Nation colonists. A brilliant inventor, he designed the revolutionary Satomobile, an idea that caused him to become the captain of industry in his era. During a police search of his secret factory, he revealed himself to be an Equalist, creating high-tech weaponry to fight against benders, and later became one of their most recognizable leaders. He was imprisoned for his crimes after the Anti-bending Revolution was put down. By 174 AG, Hiroshi grew remorseful over his actions and tried to reconcile with his daughter, Asami. When Kuvira threatened Republic City, Hiroshi was momentarily released from prison by Lin Beifong and helped to equip the prototypes of the hummingbird mecha suits with plasma saws. He ultimately sacrificed his life to give Team Avatar the opportunity to take down the enormous mecha suit and its spirit energy cannon by cutting through its platinum armor and giving them an entry.
Other known characters and organizations
|This section does not cite any sources. (November 2014) (Learn how and when to remove this template message)|
The following is a list of collective entities within the fictional universe.
Avatar: The Last Airbender
- Sandbender Tribes - Earthbenders who specialize in bending sand. They are indigenous to the Si Wong Desert within the Earth Kingdom. They are divided into separate tribes. Team Avatar utilized one of their sandsailers (a raft built for sailing on sand) while they were stranded in the desert (Toph discovered it by accident), while searching for Appa, who was stolen by Sandbenders.
- Foggy Swamp Tribe - The country-like folk of the foggy swamp, Tho, Due, and Huu being among their noted members. They use plantbending to control the vines in the swamp. They first appear in season two as hunters, and later in season three to help with the invasion of the Fire Nation. They are imprisoned when the invasion fails but are released in the finale.
- Dai Li (Chinese: 戴笠 pinyin: dài lì) - Ba Sing Se's secret police and cultural enforcers, they acted under Long Feng and then Azula. In the sequel series, the Dai Li continue as an antagonistic form against the Avatar due to being the loyal enforcers of Earth Queen Hou-Ting. It is revealed in the secret episode that the Dai Li was founded by Avatar Kyoshi.
- The Sun Warriors are the ancient civilization that the Fire Nation descended from that first discovered fire-bending. They are thought to have died out thousands of years before the main events of the series, though they live in secrecy and as protectors of the Fire-bending Masters Ran and Shaw.
- Ember Island Players are an acting troupe that mimicked the protagonists' adventures thanks to the Merchant of Cabbage documenting the group's adventures. Though not known for their acting, they do put a lot of effort in their productions. Several of the series' main characters are portrayed by the actors in the play including: Katara, Sokka, Aang, Zuko, Iroh, Suki and the Kyoshi Warriors, Jet, King Bumi, Pirates, Blue Spirit (though portrayed as if it was not Zuko's alter ego), La (in Avatar-monster form), Zhao, Yue, Azula, Fire Lord Ozai, Ty Lee and Mai, The Dai Li and Earth King Kuei Hou-Ting. During the intermission the real Aang, Katara, Sokka, Toph, Suki and Zuko aired their grievances about their portrayals. With the group complaining about Aang's portrayal by a woman, Actor Sokka's unfunny food jokes, Actress Katara being a preachy cry-baby obsessed with hope and Zuko's past mistakes being shoved in his face.
- June and Nyla are a pair of super-effective bounty hunters who travel the Earth Kingdom and were employed by Zuko in his search for Aang and later for Uncle Iroh. June (voiced by Jennifer Hale) hunts her prey with the help of her mount 'Nyla', which is totally blind but possesses a heightened sense of smell. June is confident and self-assured, and possesses impressive physical strength. Nyla is a female Shirshu (an immense, musteline-like predator) who served as the mount and companion of the bounty hunter June. A characteristic of her species is that Nyla's tongue contains neurotoxins that temporarily paralyze an opponent/target. Also like other Shirshu, Nyla has no eyes and "sees" by her powerful scent receptors; a trait that backfired when it was utilized by a fleeing Sokka by tipping perfumes into Nyla's path to confuse her.
- Combustion Man, sometimes Sparky Sparky Boom Man (real name unknown, though it is implied that Zuko knows his name) appeared in Book Three as an assassin hired by Prince Zuko to kill Aang, and served as an antagonist until his apparent death. His chief weapon is a unique method of Firebending allowing him to generate explosions from a third eye painted on his forehead, whereby he terrorizes the Avatar and his friends. He has no speaking parts and shows no mannerism except those suggesting a fierce attachment to his purpose. It is unknown if there is any connection between him and the Korra character P'Li, who demonstrated similar abilities.
- The Cabbage merchant (voiced by James Sie) is a character (never directly given a name) that appears occasionally throughout Book One and Book Two, used mainly for comic relief. The cabbage merchant was an Earth Kingdom salesman who repeatedly had his cabbages destroyed or damaged. His only speaking parts throughout the original series is to shout his catchphrase "My cabbages!": provoked first by the Earth kingdom city of Omashu's import control earthbenders; secondly by Aang and the Omashu mail delivery service; and again by Aang chased by pirates. In Book Two, his cabbages are spoilt by a 'platypus-bear' at the Ba Sing Se ferry boat center and again by Aang when the latter relocates a zoo. In Book Three, "a surprisingly knowledgeable merchant of cabbage", though never seen, supplies the story of a theatrical play mimicking, and in some scenes mocking, the protagonists' adventures. In the sequel series, another man named Lau Gan-Lan (also voiced by James Sie) runs a company named Cabbage Corp, founded by the Cabbage Merchant; Avatar: The Last Airbender - The Rift reveals that he became interested in machinery shortly after opening a cabbage-themed restaurant.
The characters of Avatar: The Last Airbender received praise from reviewers. Troy Island Mell, of IGN, felt that the story "would [not] be anywhere near as good as it is without its ability to create such strong characters". In particular, Mell enjoyed the development of Katara and Zuko throughout the first season, but thought that Zuko's relationship with his uncle was not "very organic." Jamie S. Rich of DVDTalk generally agreed with Mell's assessment of the characters. Rich also praised the fact that, unlike many cartoon television series, Avatar introduces antagonists that have a deep backstory and "are [not] just evil for the sake of it".
Jeremy Mullin, another IGN reviewer, felt that the characters were not brilliantly done, though he noted that they introduced some drama and romantic tension usually not found on Nickelodeon, especially between Aang and Katara. Lair of the Green Knight and DVD Verdict also enjoyed the romantic tension, focusing mainly on the female cast: Katara, Toph, and Azula, as well as the two minor characters, Mai and Ty Lee. Fitz at Lair of the Green Knight lauded the decision to not stereotypically fashion the woman into the "usual weak female characters" but to instead give them "strong opinions and strength". IGN also compared character relationships, complimenting "Sokka and Princess Yue's forbidden love" while criticizing Iroh and Zuko's relationship as not being executed properly. DVDVerdict felt that some minor characters, especially Mai and Ty Lee, were "love em' or hate em'" characters. Gabriel Powers of DVDActive thought that while the characters fit into neat "archetypes", it was not a bad thing and fit well with the series.
In 2008, Avatar: The Last Airbender was awarded a Peabody for its "unusually complex characters". This makes the cartoon one of few animations to win the award and the only one to be cited for its character development.
M. Night Shyamalan originally offered the roles of Aang to Noah Ringer; Sokka to Jackson Rathbone; Katara to Nicola Peltz; and Zuko to Jesse McCartney. In selecting Nicola Peltz, Shyamalan commented that he did not want to make The Last Airbender without her, saying that "I said that only once before in my career, and that was when I met Haley in The Sixth Sense auditions." In February 2009, Dev Patel replaced McCartney, whose tour dates conflicted with a boot camp scheduled for the cast to train in martial arts.
The casting of all-white actors for main protagonist roles in the live-action, Asian-influenced film triggered a negative reaction which was marked by accusations of racism, a letter-writing campaign, and a protest outside of a Philadelphia casting call for movie extras. Jackson Rathbone dismissed the complaints in an interview with MTV, saying, "I think it's one of those things where I pull my hair up, shave the sides, and I definitely need a tan. It's one of those things where, hopefully, the audience will suspend disbelief a little bit." Shaun Toub, who plays Iroh, also defended the casting choices. He noted that "if they would have put all Asians in a certain nation, I think then there would be people who come out and said, 'Well, now you're stereotyping, saying that anything that has to do with martial arts has to do with Asians and chop suey and all that.' So it's nice to mix it up and just do the unexpected."
Movie critic Roger Ebert was one of the critical voices against the casting decision. When asked about selection of primarily white actors to portray the characters, he said, "The original series Avatar: The Last Airbender was highly regarded and popular for three seasons on Nickelodeon. Its fans take it for granted that its heroes are Asian. Why would Paramount and Shyamalan go out of their way to offend these fans? There are many young Asian actors capable of playing the parts." Jevon Phillips of the Los Angeles Times noted that despite Shyamalan's attempts to defuse the situation, the issue will "not fade away or be overlooked", and that this film exemplifies the need for a debate within Hollywood about racial diversity in its films. Popular Korean cartoonist Derek Kirk Kim reacted to the film's casting by comparing it to a hypothetical film which depicts white actors wearing traditional African clothing and eating traditional African food in traditional African huts. Shyamalan, however, countered that "this movie, and then the three movies, will be the most culturally diverse tentpole movies ever released."
