I Was Quite The Looker: A flashback of her in her teenage years shows that yes, she was indeed quite a looker.
Parental Substitute: After Katara and Sokka's mother dies and their father leaves to fight in the war, she becomes this for them.
Runaway Fiancé: She was once arranged to be married to Pakku, but she ran away to the Southern Water Tribe.
The Blue Spirit
A mysterious figure known for his iconic oni mask. With his incredible badassery and excellent stealth skills, he tries to protect Aang from Admiral Zhao. It turns out the man behind the mask is Zuko, who wanted to free Aang so that he could capture him. In later episodes, Zuko also uses the Blue Spirit's identity to escape his problems. Iroh eventually calls him out on this and Zuko abandons the Blue Spirit at his urging.
Badass Normal: The Blue Spirit can hold his own against skilled Benders with just his swords. Zuko never Firebends while in this persona, presumably as a means of protecting his secret identity.
Fights Like a Normal: Could firebend if he chose, but sticks solely to his dual swords so as to protect his identity.
As a young boy, Jet's family was killed by the Fire Nation. Swearing vengeance, Jet became a dashing rebel against their forces, forming a Merry-Men esque group of freedom fighters with other war orphans. However, Jet has an extremist side and is willing to destroy the Fire Nation by any means necessary. After getting called out by Katara and Sokka, Jet realized the error of his ways and tried to start over, only to get brainwashed into an agent of the Dai Li by Long Feng. And then killed by him when he tried to break free.
Fatal Flaw: Even as The Atoner, he's completely incapable of thinking of the Fire Nation as anything but Always Chaotic Evil. However, he does get a better idea of how to treat them without going off the slippery slope. Before his development, he would've gladly flooded a Fire Nation-controlled town full of Earth Kingdom civilians. After, he tries to keep his anger under control and simply gathers evidence to report to the police. note Tries, but fails.
Freudian Excuse: He lost his family to a Fire Nation raid, much like how Katara lost her mother.
Kick the Dog: Perfectly willing to attack innocent people, as long as they're Fire Nation.
Knight Templar: Particularly in his first appearance. To him everyone in the Fire Nation is evil and must be destroyed, even if they are harmless elderly people or if doing so would wipe out scores of innocent people in a town that is merely being occupied by Fire Nation troops.
Manipulative Bastard: In his debut episode, his interactions with Aang, Katara, and Sokka are extremely manipulative. He frequently compliments them; this is not merely an example of him being The Charmer as some compliments are more subtle than others, such as implying that Katara was responsible for Sokka's supposed Out-of-Character Moment. This not only makes her feel good, it neatly deflects them from wandering down any nasty trains of thought. When he realizes that Sokka and the other two have a split over their trust of him, he plays them against each other while still trying to court each side. He continues to try to win over Sokka even near the end of the episode; not because he thinks he will be successful, but to keep up appearances.
In his second appearance, he tries to tempt Zuko into joining the Freedom Fighters by cleverly picking up that A) Zuko's the kind of guy who believes he deserves better that what he's getting and B) despite his gruff nature, he will help people who he recognizes a similar situation in (Jet thought Zuko's scar marked him as a fellow victim of the Fire Nation). Jet's only flaws in his plan is that he doesn't understand Zuko and Iroh's relationship and it isn't until too late that he realizes Zuko's a Firebender.
Not So Different: Twice. First to Zuko and then to Katara (Aang makes the comparison to the latter).
The Freedom Fighters are a handful of children from (apparently) all over the Earth Kingdom who have been orphaned by the attacks of the Fire Nation. Led by Jet, they are a Ragtag Bunch of Misfits who pretty much throw monkey wrenches into Fire Nation activity wherever they can.Longshot and Smellerbee show up with Jet en route to Ba Sing Se in Season 2. Pipsqueak and The Duke show up in Season 3. The rest of the freedom fighters are pretty much never mentioned again.
"So this is your girlfriend... no wonder she left. She's way too pretty for you."
A skilled bounty hunter, June is out for money and doesn't care who she has to work for to get it. She collects bounties with Nyla, her pet Shirshu, a ferocious beast with an incredible sense of smell. When she inadvertently damaged Zuko's ship while chasing a bounty, Zuko had her hunt the Avatar as compensation. In the finale, she was recruited by Zuko to track down Iroh.
Back for the Finale: She comes back in Sozin's Comet to help the Gaang find Aang. When that fails, she is instead asked to find Iroh, and successfully does.
Fluffy Tamer: Though not at first. In her first appearance, she has no problem with whipping her Shirshu when it under-performs. Later, she seems to have adopted this behavior, calling it her "Snuffly-Wuffly."
Juggle Fu: And seemingly the reason Toph likes her!
The Lad-ette: Spends her spare time in taverns arm wrestling burly men.
""I've already got a buyer, a nobleman in the Earth Kingdom. Unless, of course, you kids have two hundred gold pieces on you right now?"
The Pirate Captain and his crew first appear in the first season episode The Waterbending Scroll. Aang and his friends come aboard their ship to browse and Katara steals a very valuable waterbending scroll that The Pirate captain said he had gotten "at a most reasonable price, free" Afterwards the pirates chase after Aang and his friends to take the scroll back, they escape, then the pirates team up with Prince Zuko who is hunting The Avatar. At first The Pirates and Zuko work well together as they manage to catch Aang and his friends but then Sokka convinces the pirates to renege on their deal with Prince Zuko at which point a Mêlée à Trois battle ensues, Aang and his friends manage to escape. The Pirates ship and Prince Zuko's River Boat get destroyed in the process, and the pirates are not seen again until The Waterbending Master Episode where Admiral Zhao hires them to kill Prince Zuko. After that they are not seen again.
Badass Normal: The Pirate Captain is skilled enough with a sword to take Prince Zuko on Mano A Mano.
Pirate Booty: The Pirates have quite a collection of things that they market as "exotic curios"
Pirate Parrot: Actually it looks more an Archaeopteryx, which is a prehistoric ancestor of modern birds, his pet is aptly described by Sokka as a "pet reptile-bird" Word of God states his pet is an Iguana-Parrot.
In the Earth Kingdom capital of Ba Sing Se, a group called the Dai Li keeps the war with the Fire Nation a secret, in order to maintain cultural order. A man who has fought long and hard for his position, Long Feng serves as their Big Brother-like leader. Using the Dai Li to keep himself in power, Long Feng manipulates both the city and the Earth King himself, whom Long Feng uses as a puppet ruler. After getting exposed by the Gaang, he tried to get back in power by working with Azula and double-crossing her at the moment of triumph. That didn't work out too hot.
Affably Evil: Despite being very evil, he's also very polite and collected.
Worthy Opponent: He believes he and Azula to be this to each other at the end. Azula disagrees and practically laughs at the very notion of it.
Long Feng: "You've beaten me at my own game."
Azula: "Don't flatter yourself. You were never even a player."
Yellow Peril: Though like Azula, not ethnically offensive because everyone else happens to be Asian.

"It's been a long time since I've added a child's face to my collection. So... how may I help you?"
One of the oldest spirits in the Spirit World, Koh is a nightmarish centipede creature with a dangerous hobby of stealing faces. If he sees a face that makes even the slightest twitch of emotion, he will snatch it off and wear it as his own. Although he was attacked by Avatar Kuruk, he holds no grudge against the other Avatars. Because of his age, he is privy to many secrets of the world around him. So if Aang comes knocking on his door for help, who is he to refuse? There's always room for one more...He only appears in one episode (three technically, but the other two were a flashback to that episode and a cameo), and barely does anything, but he's so damn creepy that everyone remembers him.
Anti-Villain: His actions suggest that he's simply amoral, not pure evil. He stole the face of Avatar Kuruk's lover to punish him for his arrogance, and bears no ill will towards Aang or any other incarnation of the Avatar for Kuruk's attack on him because he knows they're not the same person. Furthermore, he willingly told Aang the locations of the Ocean and Moon Spirits and the danger they were in, albeit in a cryptic and riddle-filled manner and while constantly trying to steal his face.
Big Bad: Not in the series proper, but he is so in the flash game which serves as the bonus episode between Book 2 and Book 3, trying to steal Aang's face and having several spirits under his command to lead Aang astray from his quest to talk to his previous lives.
Writers Cannot Do Math: Koh claims that a past Avatar tried to kill him "Eight or nine-hundred years ago." but Kuruk is the only Avatar to have attacked Koh, supported by the fact that the online game confirms he showed Kuruk's wife's face when he mentioned the girl to Aang. Even taking into account some Avatars' extended lifespans, it's very unlikely that Kuruk lived any more than 450-550 years previous. Justified in that the writers wrote the line before they wrote the encounter.
Heel-Face Turn: He's one of the many wrestlers who kidnaps Aang and Toph, but he (and The Hippo) eventually come to the good side to help with the invasion. When Toph senses their presence, she initially thinks they want to fight, but The Boulder explains they are there to help. "The Boulder and The Hippo no longer fight for the entertainment of others, now we fight of our kingdom!"
The Brute: The Boulder is very strong, and is an excellent earth bender, but when Katara says that he could be a possible Earth-bending teacher to Aang, Aang reminds her "That Bumi told me to find somebody who listens to the earth, he's just listening to his big muscles."
What Happened to the Mouse?: He and the other wrestlers are not seen again after Episode Six of Season Two. Although he and The Hippo do come back to help invade The Fire Nation during Season Three's The Day of Black Sun. They also make cameo appearances during the end of the third season finale.
The Big Bad Hippo
Voiced by Kevin Michael Richardson
The Big Bad Hippo was an earth-bending wrestler in EARTH RUMBLE VI, just like The Boulder. He almost beat The Boulder by stomping his feet and jumping up and down, which caused him to almost fall out of the ring. This was The Hippo's signature move which was called "Rocking The Boat". The Boulder however manages to catch his balance and defeats The Hippo by lifting him up in the air using his earth-bending and tossing him out of the ring.
Mighty Glacier: Is slow but incredibly powerful, he is able to withstand an earth-bending attack from The Boulder to the back of his head, and during the opening of their fight, caught rocks The Boulder threw at him, chewed them up and spit them out.
Third-Person Person: Just like The Boulder, he constantly refers to himself in the third person, but The Boulder is much more refined. The Hippo refers to himself and generally talks in Hulk Speak.
Word of God: According to dvd commentary, The Hippo is an Expy of real life wrestler Andre The Giant, and a Nintendo character named King Hippo from a 1987 Game, called Mike Tyson's Punch-out.
The Earth Rumble VI Wrestlers
Earthbenders participating in the Earth Rumble VI earthbending tournament, where they get beaten by The Boulder. Later they kidnap Toph and Aang, and get curbstomped by Toph for their troubles. After that, they're never seen again.
Fire Nation Man
Foreign Wrestling Heel: Even though he is an Earthbender, his Gimmick is that he's a Fire Nation Patriot. While performing, he also talks in a stereotypical thick Eastern European accent. He was easily beaten by The Boulder, and was Ain't Too Proud to Beg screaming "NO! PLEASE!", before The Boulder sends him flying out of the ring.
Word of God: Avatar Wikia.com and dvd commentary state that he immigrated from The Si Wong Desert and is a sand-bender.
Cool Mask: His mask is reptilian looking, and his Gimmick is crawling around on his hands and knees like a lizard.
The Voiceless: Other than some grunts and groans, he never says a word.
Cool Mask: Its not a mask, but its still cool. He wears a very unique pair of goggles and head gear.
Finishing Move: It's not his finishing move per se, but it's what he's known for. His signature move is tunneling under the ground, they don't call him The Gopher for nothing.
The Voiceless: Except for one very loud battle cry, he never says a word
Xin Fu and Yu
Voiced by: Marc Graue (Xin Fu), Sab Shimono (Yu)
"Nobody cheats Xin Fu!"
"If you pay for the whole year in advance I'll bump you up to the next belt."
Xin Fu is the coordinator of the wrestling tournament in which Toph participates. When he thinks Toph cheated him out of the prize money he offered for her defeat, he kidnaps her and demands the prize money back as ransom. He is later hired by Toph's father to bring her home after she runs away.Yu is an Earthbending teacher in Toph's hometown. He was hired to teach Toph Earthbending, but he grossly underestimated her abilities and thought she would never get passed the beginner level. Once Toph runs away, he is hired to work alongside Xin Fu in retrieving her.
Affably Evil: Master Yu, who is very polite and softspoken for a bad guy.
Bounty Hunter: Not their actual occupation, but they're willing to do anything for a buck.
Brains and Brawn: Yu actually thinks things through, realizing things like trying to take down two people with large bounties in a Bad Guy Bar full of desperate outlaws will probably mean having to take on the whole room. Xin Fu will just charge in and beat up the half dozen guys in his way.
Fate Worse Than Death: Being stuck in a metal cage until they are either freed by a passerby or die of starvation/dehydration/what have you since Earthbenders can't bend metal. Which ends up happening, we're never told.
"You're right, Zuko. I've seen that girl in here quite a lot. It seems to me she has quite a little crush on you!"
Jin is a citizen of Ba Sing Se and a regular patron of the tea shop where Iroh and Zuko work. She nurses a crush on Zuko and decides to ask him out on a date, which doesn't go very well. She appeared in one of the Avatar comics that came out between seasons two and three and had a two-second cameo in the first episode of the third season. Despite her very short screen time, she has gained a decent measure of popularity with the fandom.
Cat Smile: One of the reasons fans like her quite a bit.
The Ditz: Gets accused of this sometimes for not realizing that Zuko was a Firebender after he lit all the candles around the fountain, though it's entirely possible that she knew and just didn't think it was bad. After all, there is no war in Ba Sing Se. Alternatively, she may not know the specifics of bending, since she doesn't appear to be one herself.
Star-Crossed Lovers: One sided, even if she wasn't a character of the day, despite a cameo in a later episode and a minor role in a comic, she's a refugee of the Earth Kingdom unaware she has a crush on the prince of the Fire Nation. Even without Mai, those odds seemed unlikely.
"You think you're the first person to believe your war was justified? Countless others before you have come here seeking weapons or weaknesses or battle strategies!"
Wan Shi Tong is known as the great knowledge Spirit, which takes the form of a large black owl with a white face. Wan Shi Tong created the Spirit Library to house his ever growing collection of knowledge, and brought it to the mortal world so that humanity might benefit from such wisdom. However, eons of seeing humans abusing his knowledge for the sake of conflict has turned Wan Shi Tong to ban humans from his library for their misuse. When the Gaang arrive there, Aang promises not to abuse the knowledge they gain from the library, but quickly go back on their word and learn about the Fire Nation's vulnerability during a solar eclipse. Wan Shi Tong decided enough was enough and took his library back to the Spirit World while simultaneously trying to kill the Gaang for what they did.
Above Good and Evil: He cares nothing for the conflicts of humanity and demands that his knowledge only be obtained by those who seek it for its own sake with no intention of using it against someone else.
Bilingual Bonus: Wan Shi Tong literally means "He who knows ten thousand things."
Genius Bruiser: Holds eons' worth of knowledge, and horrific strength to go with it.
Humans Kill Wantonly: The Spirit is fed up with humans seeking knowledge just so they can find new ways to fight their wars.
Informed Ability: Wan Shi Tong stated that he learned all styles of Waterbending when he cornered Katara. If that means he can waterbend himself or simply knows how to counter it wasn't found out. He doesn't know Sokka style, though.
They Know Too Much: Played with in that the knowledge the Gaang has wouldn't do anything to him personally since he has no ties to the Fire Nation, but just the fact that they have this knowledge they intend to use for warfare is enough to silence them.
Voice of the Legion: He speaks like this, and it goes from creepy to horrifying when he tries to kill the Gaang.
Whatever Happened To The Mouse: When he pops up in Legend of Korra, it turns out his opinion of humans hasn't improved much in the seventy years since his encounter with the Gaang, and he still holds a grudge against the Avatar after Aang misused his knowledge after promising not to. What's more, Professor Zei's corpse is still in his library.
"Just let her go, and I'll give you the information you want."
Kya was the mother of Sokka and Katara and the wife of Hakoda. Her death during a raid on her home had a profound impact upon both her children. Katara wore her mother's necklace as a memento of her affection.
Good Mom: She didn't hesitate for a second when it came to protecting her daughter from Yon Rha.
"I'm not leaving... I can't... I've spent too long trying to find this place... There's not another collection of knowledge like this on Earth... I could spend an eternity in here."
Professor Zei was the head of the Anthropology Department at Ba Sing Se University. An ambitious cultural anthropologist, he was well-traveled and highly educated in exotic cultures. His thirst for knowledge brought him to strange, remote, and often dangerous places. Zei was an eccentric man to whom knowledge was priceless. He got very excited at the prospect of learning anything about history or the world around him. A map of his travels showed he had been everywhere in the world, except the Fire Nation. Even though he had discovered many lost civilizations over the years, he longed to find the "crown jewel" of ancient discoveries: Wan Shi Tong's Library.He never managed to find Wan Shi Tong's Library until he ran into Aang and his friends in The Si Wong Desert. He explained to them that he made several expeditions into the desert but almost died each time. He finally fulfills his life long wish, by flying on the back of Appa, Aang's Flying Bison. After they get into Wan Shi Tong's Library, Wan Shi Tong initially refuses them entry , but lets them pass under the condition that they provide him with new knowledge. Unlike Aang and his friends who wanted to use Wan Shi Tong's Library to help them find possible ways to help them defeat The Fire Nation, Professor Zei wanted to find the library simply because he was a lover of knowledge. In fact when Wan Shi Tong finds out about this, he sinks his library into the desert sand and tries to keep Aang and his friends trapped for eternity. Professor Zei willingly chooses to stay behind, and in The Legend of Korra it's revealed that he died there and his corpse is rotting in the library.
Adventure Archaeologist: Professor Zei divides his time teaching Cultural Anthropology at Ba Sing Se University and looking for lost civilizations.
Ambiguous Disorder: Has no idea that Aang and Sokka thinks the word Buttresses is funny, and takes their lie about loving architecture at face value.
Bad Ass Book Worm: We never actually see how much of a bad ass he is, but he has to be one to have journeyed through The Si Wong Desert several times and to survive.
Be Careful What You Wish For: He wanted to spend an eternity in The Library and he got his wish, his corpse is still there in The Legend of Korra, seventy years after Avatar Aang was last there.
Buried Alive: Essentially and by his own choice this is what happens to him, because he chooses to stay behind in Wan Shi Tong's Library even though Wan Shi Tong was burying it underneath The Si Wong Desert.
Fate Worse Than Death: Apparently Wan Shi Tong took no efforts to provide him with food and water, even though he was the only person to ever visit his library, simply because he loves knowledge for its own sake. Its not explained how long it took for him to die, while trapped in the library. What's worse is that aside from the few people who are familiar with The Gaang's history, hardly anybody remembers him, he left behind no legacy.
Hypocritical Humor: Wishes he could talk to Appa commenting wistfully on "the stories this beast could tell." When Momo tries to talk to him, he says "Shush! Chatty monkey!" He doesn't even know Momo is a Flying Lemur.
