While crying on the edge of a cliff, Korra is visited by the previous Avatar, Aang, telling her she has finally connected with her spiritual-self. With the appearance of all the previous Avatars, he then restores her lost bending abilities, after which Mako appears and the both of them admit their love for each other.
Aang restored Korra's bending and gave her the ability to restore that of others. After the Equalists' defeat, Korra traveled to the Southern Water Tribe, hoping that Katara could undo Amon's action. The old healer was unable to, however, and a heartbroken Korra ran off to grieve on her own.
Does everyone get their bending back in Legend of Korra?
Korra subsequently used the technique on Lin Beifong, effectively restoring her earthbending. During the following months, Korra also restored the bending of everyone else victimized by Amon in Republic City, with the exception of Triad criminals.
In 171 AG, after being poisoned by the Red Lotus, she retreated to the Southern Water Tribe in an attempt to heal her body and her mind. Although she was able to recover physically after two years with Katara's help, Korra continued to have visions about Zaheer and the attempt on her life.
One of the heavy hitters of The Legend of Korra was when Korra ended the Avatar Cycle and began a new one. This act destroyed her link to all her past lives. Because of this, she and every Avatar after her will no longer be able to gain the wisdom of their past lives and will only have Korra to mentor them.
In some ways, Aang and Korra are complements of the other, and what one excelled at the other struggled with. However, when you compare their ages, skill sets, and the villains they faced during their seasons, Korra comes across as stronger and more powerful than Aang.
While it was initially only doable on a full moon, Yakone and his two sons learned how to do it at any time. As such, Korra had to learn how to tackle a bloodbender to save Republic City. It was difficult at first, but she later proved to be strong enough to break free from a bloodbending hold.
While the series finished in 2014, the adventures of Korra and Asami didn't end there. DiMartino continued Korra's story in comic book form, with two new arcs published via Dark Horse Comics. Not only do they extend the narrative of The Legend of Korra, but they show Korra and Asami as a full-fledged couple.
1. Iroh. The wise, tea-loving Fire Nation elder gets top pick as the strongest bender in the series. Iroh's (Mako S1-2, Greg Baldwin S3) strength comes not just from his bending, but his years of experience and profound wisdom.
It is still possible for Korra to get in the Avatar State (which is the unified state with Raava) but she can not talk with Aang or other past Avatars and use their knowledge. Korra became the first Avatar.
Although Korra is able to bend all four elements, while being capable of entering the Avatar State, Korra is still in the process of perfecting her airbending skills as well as having a true connection and understanding of her spiritual self to complete her training as a fully realized Avatar.
In his 20s, Zuko found a juvenile dragon that he named Druk. Over the years, Druk grew up and became Zuko's loyal companion, and the two of them flew around the world together. At some point in his life, he married and had a daughter named Izumi.
Lightning bending is one of the strongest abilities in Avatar: The Last Airbender, with Azula's lightning attack nearly killing Aang for good. It's also one of the rarest techniques, with only Ozai, Iroh, and Azula able to generate lightning on their own. Even Aang, the avatar, and Zuko could only redirect lightning.
Korra's final season didn't even get to air on TV — halfway through season three, just when many fans believed the show was at its creative peak, Nickelodeon pulled it from its TV schedule, citing declining ratings.
By the end of The Last Airbender, the only characters shown to be capable of it were Fire Lord Ozai, Princess Azula and General Iroh, all of whom are Fire Nation royalty. Zuko famously never managed to learn how to produce lightning himself, settling instead for redirecting others' attacks.
Korra isn't the last Avatar, but just the representation of a new cycle of Avatars. Nowhere in the series does it imply that when Korra dies, there will be no more Avatars again, or that the Avatar cycle should end.
