Avatar Last Airbender Characters

The animated television series Avatar: The Last Airbender and its live-action film adaptation, The Last Airbender, feature an extensive cast of characters created by Bryan Konietzko and Michael Dante DiMartino. Taking place in a fictional universe composed of four sovereign nations, the series deals with a war started by the belligerent Fire Nation as an attempt to conquer the world. The Avatar, a being who represents the spirit of the Earth itself and alone holds the power to counter the Fire Nation aggression, has been mysteriously missing for the past 100 years, plunging the world into a century of war. The first phase of war ended with a genocide of the Air Nomads, near extinction of the Water Tribes, and extensive colonization of the Earth Kingdom, thus setting up the world in which the characters of the series live.

The main protagonist of the series is Aang, the most recent incarnation of the Avatar, who is released from an iceberg after being frozen for 100 years. With his new friends Katara and Sokka, and later Toph, Aang sets out to master the three unlearned bending arts and end the war that has ravaged the world during his absence. The series also focuses on Zuko, the crown prince of the Fire Nation; initially portrayed as an antagonist who tries to capture Aang, but with the help of his uncle, become a deuteragonist.

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.

Character conception

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: Ba Gua for Airbending, Hung Gar for Earthbending, Northern Shaolin for Firebending, and T'ai chi for Waterbending. 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 child-like, as is commonly attributed to the "freedom" of the wind and the air. 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.

Avatar The Last Airbender

Avatar: The Last Airbender is a 61-episode, Emmy Award-winning American animated television series written and created by Michael Dante DiMartino and Bryan Konietzko. It first aired on February 21, 2005 with a one-hour series premiere and concluded its run with a two-hour TV movie on July 19, 2008 The Avatar franchise refers to each season as a "Book", in which each episode is referred to as a "chapter".

In the Avatar universe, there are people who are able to manipulate, or "bend", the four elements: Air, Water, Earth, and Fire. Along with the four elements, there are four nations that correspond with each element. Not everyone can bend an element, and those that can can only bend one. However, The Avatar is a being able to manipulate all four elements as well as communicate with the spirits. The Avatar is also born into one nation, and after dying, is reincarnated into another nation following the pattern of Water, Earth, Fire, Air. The series takes place 100 years after the fire nation declares war against all other nations and has killed off all airbenders in search of finding the avatar who has been reincarnated as an airbender, Aang. The avatar, trapped in ice for 100 years, knows nothing of the war. The series starts with Aang being accidentally freed by Katara, a waterbender. The series then primarily follows the adventures of Aang and his companions, Sokka, Katara, and later Toph, as he tries to master all four elements and defeat the fire nation. There is also a strong secondary focus on Zuko, the banished and disinherited crown prince of the Fire Nation. Zuko was scarred in a duel with his own father, the current Fire Lord. Zuko is obsessed with trying to capture Aang in order to regain fathers favour and in doing so restore his honor.

Through this heightened sense, she can identify people's locations, their distance from her, and their physical build. This 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 acquired an acute sense of hearing, enabling her to recognize people by the sound of their voices and to eavesdrop on distant conversations.

At the end of the series, his self-stated wish is to resume operation of a tea-shop therein.

• 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 the pursuits of relaxation and amusements than on the pursuit of the Avatar, often clashing with the goals and aspirations of his nephew.

The characters of Avatar: The Last Airbender received both praise and criticism 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 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.

Casting

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.".
