The Avatar is ''the'' most powerful being in the ''Avatar'' universe. It is the result of a permanent fusion between Wan - the first man to not only possess the power of more than one element, but the first human bender as well - and Raava, the spirit of light and peace. The Avatar is a reincarnation of Wan throughout the millennia, starting a cycle that began the moment Wan died.

The Avatar is able to access the power of Raava and his or her previous incarnations in what is called the Avatar State, giving them unlimited power for as long as they are in said state. However, any given incarnation of the Avatar is not immortal, and if he or she is killed in the Avatar State, the Avatar Spirit will die and the cycle will end (though Raava herself will survive the death of the Avatar Spirit, and will eventually reform elsewhere).

The Avatar's mission in life, a task set forth by Wan himself, is to maintain balance of the world. This job includes bringing peace between groups in conflict, or defeating threats to world peace such as imperialist tyrants bent on conquest. The Avatar is also the spiritual leader of the world; due to being half spirit, the Avatar is most powerful in the Spirit World, as opposed to other humans who normally are powerless in comparison. The Avatar must master the four elements and attain a certain degree of balance within themselves; they are then referred to as a "fully realized Avatar".

For tropes specifically relating to Korra, Aang, the Avatars who preceded them, or Wan himself, please visit the various pages in the Character pages for both ''Avatar: The Last Airbender'' or ''The Legend of Korra''.

----

* TheAtoner: Until perhaps the Harmonic Convergence of Korra's time, the Avatar's mission in life is partly to honor Wan's dying wish to continue making up for his grave mistake in releasing Vaatu.
* {{Badass}}: When you're the most powerful entity in your universe, you qualify as this ''at worst''.
* BigGood: The Avatar is to attain this goal once they have mastered all four elements and found inner peace. This usually negates an Avatar's chance to have political power, since their job is to essentially be the leader of two entire worlds.
* BullyingADragon: ''Avatar Extras'' dryly noted that most people who face or challenge a fully realized Avatar in combat are pretty easily embarrassed.
* FusionDance: The Avatar came to be when Wan and Raava fused together during Harmonic Convergence.
* GlowingEyesOfDoom: As seen above, the Avatar employs these when entering the Avatar State.
* GodIsGood: The Avatar is the closest thing to a god that the ''Avatar'' universe has, and their job is to protect the worlds and its people and spirits.
* GodInHumanForm
* GodOfGood: The Avatar is the human incarnation of Raava. She bonded herself with a human host in order to defeat her evil opposite [[GodOfEvil Vaatu]] and later bring peace to both physical and spirit worlds.
* HeroicSecondWind: The Avatar State is often used as a last resort when the Avatar requires an extra boost of power to accomplish the task at hand.
* TheJuggernaut: While not immortal, it's easy to tell that the Avatar is this trope considering how many times the word "power" has been used here.
* LegacyCharacter: Via reincarnation.
* TheNeedsOfTheMany: This is a dilemma faced by many Avatars in their lifetimes: whether or not to choose between themselves or the fate of the many in a given context. Since the Avatar is the protector of not just the entire world, but the Spirit World as well, an Avatar is usually advised to serve the needs of the many over the needs of the few. This is the reason some Avatars more or less cast off their backgrounds and ideologies (such as Yang Chen), to better serve the worlds as a whole.
* {{Reincarnation}}: The Avatar's spirit never truly dies as it continuously reincarnates into a new body at death. However, if the Avatar is killed in the Avatar State, the Avatar would truly die.
* ThouShaltNotKill: It depends on the Avatar if this trope is invoked or not. Aang was a notable pacifist who believed all life was sacred, which he was more or less chastised for by his predecessors.
* VoiceOfTheLegion: On many occasions when the Avatar speaks during the Avatar State, the Avatar will speak with apparently the voices of all previous Avatars at once, in a chilling, powerful drone.
