What makes a TV show compelling, including animated shows, is a cast of well developed and deep characters with clear inner motivations and complicated relationships with one another. This is vital, even for an action fantasy show, and viewers got just that in Nickelodeon's Avatar: The Last Airbender. Airing in the 2000s, this show brought many fans some of their favorite animated TV characters of all.

It's a show about forgiveness, destiny, and redemption, and there are all kinds of ways to categorize and measure the nature of each character in Avatar. Popular methods include the Dungeons & Dragons moral alignment chart, or even the Chinese zodiac or astrology horoscopes. When the twelve astrology signs are used on the characters of Avatar: The Last Airbender, what are the results?

12 Aries (March 21 - April 19): Prince Zuko

The horoscope begins with a fire sign, Aries. An Aries is defined as being competitive, forward-thinking, and almost recklessly brave. They are the type to act now, think later, and get things done.

Prince Zuko fits this mold nicely, as he is rash and impulsive and likes to dive right into the thick of things. He's not stupid by any measure, but neither is he the patient and calculating type.

11 Taurus (April 20 - May 20): Katara

The second astrological sign is Taurus, an earth sign. These people are defined by two broad concepts: a love of sensual pleasure and comforts, and a stubborn and reliable streak. They are solid in mind.

Katara, despite being a water-bender, fits this mold since she is a firm-handed motherly type and is persistent in everything she does. Katara is compassionate and kind, but almost as stubborn as the famed earth-bender Toph Beifong.

10 Gemini (May 21 - June 20): Sokka

It's time for Gemini, and this is a busy sign indeed. This air sign is represented by twins, since a Gemini is so busy with their intellectual and creative pursuits, they need a second body to get everything done!

Sokka is indeed creative and innovative, despite coming from a primitive tribe, and he's not afraid to build new weapons of war to help take the fight to the Fire Nation. His blueprints are rather crudely drawn, though.

9 Cancer (June 21- July 22): Iroh

Uncle Iroh in Avatar

Cancer is one of the easiest astrology signs to get along with. What defines them? These water signs are balanced between the physical and mystic realms, and cultivate deep and emotional relationships.

Uncle Iroh is a model Cancer, being a man of philosophy who can look after himself. And he's among the most gracious hosts and friends anyone has ever met.

8 Leo (July 23 - August 22): Ty Lee

The time has come for the most flashy astrology sign of all: Leo. It's a fire sign, and Leos are known for being total party animals who need maximum attention and excitement around them. They push everything to 11.

Ty Lee is a Leo herself, since she loves parties and circus performances (she's an acrobat), and she does all this to set herself apart from her many identical sisters. No one is a finer Leo.

7 Virgo (August 23 - September 22): Long Feng

Long Feng Avatar Villain

Next up is Virgo, an earth sign that is characterized by being patient, diligent, and highly logical and systematic. They are thinkers and planners, never acting rashly or emotionally.

Long Feng, the head of the infamous Dai Li, is quite the Virgo. He is cunning and calculating, but also patient and systematic as he uses the Dai Li to control the earth king and control all information flowing in and out of Ba Sing Se. It took the likes of team avatar and Azula to bring him down.

6 Libra (September 23 - October 22): Avatar Roku

Avatar-The-Last-Airbender-Roku

Libra is the one and only astrological sign not represented by an animal. Instead, it's symbolized by a set of scales, since this air sign is dedicated to balance, harmony, and keeping everyone happy. They are quite selfless that way.

Avatar Roku was a model Libra, and when his good friend, Fire Lord Sozin, described his plans for conquest, Roku objected at once, despite being a man of the Fire Nation himself. As an elderly man, he even saved Sozin's life, at the cost of his own. He didn't want the Fire Nation to lose its leader.

5 Scorpio (October 23 - November 21): Princess Azula

Scorpio is sometimes mistaken for a fire sign, but it is actually a water sign, since it is based on calculations and tapping into mystic energies. A Scorpio is known for laying down plans ahead of time and waiting for the right moment to make a move.

There's nothing evil about Scorpios, but this personality trait is ideal for villains such as Azula. She is ruthless, but also more cunning and patient than her brother Zuko, and she has gotten much closer to capturing Aang than Zuko ever did.

4 Sagittarius (November 22 - December 21): King Kuei

This may seem like an odd choice at first. But the fire sign Sagittarius is defined by a person's love of exploring the world and finding new things to discover, then telling tales about it later to an enraptured crowd.

In the Dark Horse Avatar comics, King Kuei broke free of the stuffy trappings of royalty and decided to roam the land as a free and humble man, bringing only basic clothes and his pet bear, Bosco. He wants to see and experience everything, and that's a true Sagittarius.

3 Capricorn (December 22 - January 19): Toph Beifong

Toph in ATLA

What does it mean to be a Capricorn? This sign is represented by a mythical sea goat, though it's actually an earth sign that derives strength from within and diligently pursues projects with great enthusiasm and initiative.

That sounds just like Toph Beifong, who likes to take charge and come up with her own plans and then pursue them with the stubborn passion of a true earth-bender and Capricorn.

2 Aquarius (January 20 - February 18): Jet

jet avatar last airbender

Don't be fooled by the name. Aquarius is an air sign, and anyone born under this sign is free-spirited and chafes under laws and rules. Their motto is "I believe in the power of the people!"

That's just like Jet, a freedom fighter who will do anything to fight back against the Fire Nation and recruit anyone who will help him. He tends to get carried away, however, putting him at odds with team avatar.

1 Pisces (February 19 - March 20): Aang

At last, the avatar himself arrives. Pisces is the final water sign, and anyone born as a Pisces is highly imaginative and empathetic toward others. They are not afraid to feel, or to connect to others. Pisces also learns many lessons from the other 11 signs.

Avatar Aang, as an air-bender and a compassionate person, is quite a Pisces, and he would much rather talk out a problem and connect with people rather than fight them. He even reached out to Zuko in season 1, after Zuko rescued him in his Blue Spirit disguise. Zuko rejected the offer of friendship, though.
