人...人家才不是为了你在转动！

地球君

人...人家才不是为了你在转动！

Mako

作为一位性格严肃的火宗，英俊而忧郁的马科一直照顾着他的弟弟博林。街头成长的经历让他变得冷酷坚韧，但马科深爱弟弟，愿意为保护他们俩做任何事。他专注于带领队伍赢得御术竞技赛并拿下大奖，而当科拉闯入他的生活后，马科那严控的世界变得有些混乱。

Bolin

无论共和城周围的情况多么紧张（而且确实很紧张），博林总能带来欢笑。作为马科的弟弟和御术竞技赛队友，博林性格更为随和，喜欢享受生活。尽管童年艰辛，博林脸上总是挂着笑容，身边总有佳人相伴。事实上，正是博林将马科介绍给了科拉。但博林并非小丑，当需要认真起来施展土宗之术时，这位坚强的选手绝对能应付自如。

Aang

12岁的转世神通，气宗一族的末裔，被赋予维护水土火气四国和平共生的重任。

Katara

善良、博爱、宽容、温柔、坚强并勇敢。最能说明她性情的情节正是阿帕失踪之后，安对于身边每一个朋友都十分不友好，而安的小团队困于沙漠中，缺食少水，每一个人都极为消沉（当然，她的开心果哥哥是个例外），在这个时候卡塔拉表现出了一个女孩特有的美－－宽容、柔顺、慈爱而顾全大局。当安对她大发其火的时候，她仍然安慰他，团结照顾每一个人。要知道，面对安的没来由的怒火她并不是忍气吞生，忍，只是把火气压回自己的肚子里。卡塔拉的境界更高，她能理解因为失去阿帕安心中的痛苦，而对于他始终谅解，并一直呵护、开导他。这对于一个人来说是极难得的，非高尚的心胸做不出来。 另一方面，在北极水宗族的国家里学御水术的事件又表现了卡塔拉的坚强和勇敢。水之国的御水师因为传统和明显的对于女孩子的岐视而不愿教卡塔拉御水术，使得卡塔拉大怒，向大师发起挑战，即便被打得狼狈不堪也决不退缩，充分向这位大师展示了自己的坚强和悟性。这改变了大师对于她的看法，大师最终改变了自己的主意，收了卡塔拉这个弟子。这个情节也反映了卡塔拉的温柔并不是因为性格怯懦。 再有，卡塔拉在安很短的时间内学会了她苦练多年的技艺时的嫉妒和看到新来的托芙不遵守他们队伍中的规距时的暴怒也反映了她身上具有的普通人的性情。事实上上述两件事无论发生在谁的身上谁都会那样的表现的。这使得卡塔拉这个角色更加的人情味和丰满。

Roku

Roku was the Fire Nation-born Avatar immediately succeeding Avatar Kyoshi and preceding Avatar Aang. Roku's memory served as a guiding force for Aang throughout his quest to end the Hundred Year War. Roku was a wise and merciful Avatar with good intentions, though he himself acknowledged that he was too indecisive during his life. Roku's long friendship with Fire Lord Sozin resulted in his reluctance to end his friend's life and thus his imperial ambitions. This ultimately led to Roku's death, preventing him from stopping a war which would last for one hundred years. Aang inherited Roku's burden of healing the war-torn world, and Roku firmly believed Aang was destined to amend his mistakes.

Kyoshi

Kyoshi was the Earth Kingdom-born Avatar immediately succeeding Avatar Kuruk of the Northern Water Tribe, and preceding Avatar Roku of the Fire Nation. She died at the age of 230, making her the oldest known human. Kyoshi was a tall woman, possessing the largest feet of any Avatar. Her traditional weapons were golden metal fans which, in addition to her manner of dress and style of fighting, were adopted by the Kyoshi Warriors of Kyoshi Island, her homeland. Unlike her successors, Roku and Aang, Kyoshi was determined that only true justice could bring peace, and had no qualms about killing enemies to achieve this goal. Employing these methods, she was a generally effective Avatar. However, some of her actions also caused long-term problems for the Earth Kingdom; while ushering the world into a 233-year-long era of peace, the death of Chin the Conqueror and her foundation of the Dai Li would lead to the decline, corruption, and fall of her home country. Because of this, Kyoshi later came to deeply regret the creation of the Dai Li.

Korra

Korra couldn't have less in common with Aang, the previous Avatar. A 17-year-old girl from the Southern Water Tribe, she is as hot-headed and eager as she is talented. When she runs away to Republic City, her stubbornness and impatience get in the way of her bending studies, but it is clear from the start that she is destined for greatness. Korra discovers many new things in Republic City - some amazing and some terrifying. Whether its honing her bending skills in the Pro-bending Arena, facing off with street thugs or facing an anti-bending rebellion, Korra learns that being the Avatar comes with many dangers and responsibilities. As if being a teenager wasn't hard enough on its own!

Asami Sato

Asami Sato is 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 began a romantic relationship with her best friend, Korra.

Tenzin

Tenzin 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

Lin Beifong 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.

Kya

Kya is the second of Avatar Aang and Katara's three children and their only daughter, as well as the couple's only waterbending child. As such, she always felt a stronger connection with her mother.

Jinora

Jinora is the first child and eldest daughter of Tenzin and Pema and granddaughter of Katara and the late Avatar Aang. She lives on Air Temple Island with her parents and three younger siblings: Ikki, Meelo, and Rohan. Besides being a master airbender, Jinora has an avid interest in books and is a quiet girl in general. She has a natural affinity with spirits and, prior to the reopening of the spirit portals, was one of only a handful of humans who could communicate with and perceive the spirits in the physical world. As a result, she became Avatar Korra's guide into the Spirit World. Sometime after 171 AG, she entered a romantic relationship with Kai.

Tonraq

Tonraq is a powerful waterbending master and chief of the Southern Water Tribe. Born as heir to the chief of the Water Tribes, he is the older brother of Unalaq. Growing up in the Northern Water Tribe, Tonraq served as the Northern military's general in his youth, though was banished and disinherited following the destruction of a sacred spiritual forest at his hands. 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.

Meelo

Meelo is the third child and the first son of Tenzin and Pema, and grandson of Avatar Aang and Katara. He resides on Air Temple Island with the rest of his family. The young airbender has two older sisters, Jinora and Ikki, and a younger brother named Rohan.

Ikki

Ikki is the second child and youngest daughter of Tenzin and Pema, and the granddaughter of Avatar Aang and Katara. She has three siblings: an older sister named Jinora and two younger brothers named Meelo and Rohan. The entire family resides on Air Temple Island, near Republic City. Ikki is fun-loving, energetic, and extremely talkative.
