Avatar: The Last Airbender is considered one of Nickelodeon’s greatest cartoons because it successfully combines beautiful animation, surprisingly complex ideas, exciting action sequences, and a compelling story. While most episodes are strong, a few, like ‘The Divide,’ aren’t as good. However, the series also features some of the best and most memorable episodes in fantasy cartoon history.
The strongest episodes of Avatar: The Last Airbender aren’t just packed with big plot twists and important character development—they also deliver exciting action and a richly detailed world that keeps you hooked. Many dedicated fans consider these episodes the heart of the series, and the best way to show newcomers why Avatar is so highly regarded.
“The Storm” Exposed Aang’s Guilt and Zuko’s Past Trauma
Season 1, Episode 12
The episode “The Storm” brilliantly used flashbacks to deepen the stories of characters like Prince Zuko and Avatar Aang. This technique is typical of the show’s best episodes; Avatar: The Last Airbender cleverly employs flashbacks to reveal important information efficiently. In fact, these flashbacks are arguably even more impactful than those found in many popular anime series.
The episode “The Storm” had incredible imagery, especially during the powerful ocean storm, and really emphasized the danger the characters faced. However, the most impactful part was Iroh’s conversation with Zuko, which showed us a vulnerable side of the prince and revealed the immense emotional weight he was carrying. This episode marked a turning point for Zuko’s character arc, subtly moving him toward redemption by portraying him as someone deserving of it. Aang’s flashback was also very effective, helping us understand the full impact of his long absence.
“The Siege of the North, Part 2” Was a Turning Point For Aang and Zuko Alike
Season 1, Episode 20
The final three episodes of Book One: Water took place in the frozen Northern Water Tribe, with “The Siege of the North, Part 2” being the standout. The episode featured exciting action as Firebenders attacked and Waterbenders defended, and Aang’s use of the Ocean Spirit highlighted the spiritual connection of the Avatar. Zuko’s actions also made this a crucial episode of Avatar: The Last Airbender.
This episode resonated with viewers by showing that the spirits were far more powerful than humans or their conflicts. Seeing the near-destruction caused by Admiral Zhao killing the Moon Spirit was both a humbling and frightening experience – a concept similar to what fans saw in The Legend of Korra with Wan’s journey through a spirit-filled world. The episode also deepened our sympathy for Zuko, revealing his father’s cruel taunts about him being “lucky to be born” as he spoke to an unconscious Aang.
“Zuko Alone” Made it Clear Ozai’s Son Was No Ordinary Villain
Season 2, Episode 7
This episode features what many consider the best flashback in the entire series, and it heavily influenced the ‘Korra Alone’ episode in Book Four of The Legend of Korra. Notably, ‘Zuko Alone’ is the only episode of Avatar that doesn’t include Aang, which allows for a deep dive into Zuko’s character as a complex antihero. We see Zuko’s past revealed with striking honesty, from the abuse he suffered from Ozai and Azula, to the comfort he found in his mother, Ursa – who was forced to leave after assisting Ozai in the assassination of Fire Lord Azulon.

A highlight of this episode was the thoughtful portrayal of Zuko. He was presented as nearly sympathetic, though not quite a hero, which subtly moved his story towards redemption. He demonstrated impressive self-control for much of the episode, only using firebending when pushed to his limit. A particularly compelling moment came when an Earth Kingdom child expressed hatred for Zuko because of his father, forcing viewers to consider who deserved more sympathy – Zuko or the boy.
“The Crossroads of Destiny” Saw Azula Rise and Aang Fall From Grace
Season 2, Episode 20
Book Two of Avatar: The Last Airbender featured many memorable events in the massive city of Ba Sing Se, including Appa’s daring rescue and Zuko’s awkward attempt at a normal life. Beneath the surface, a secret plot involving the royal advisor, Long Feng, was unfolding. This season saw Zuko begin to change for the better, while Princess Azula proved she had no interest in redemption. Instead, she became even more manipulative, first using Long Feng to take control of the Earth King, and then shockingly betraying him.
“The Crossroads of Destiny” was a truly captivating episode, largely due to its intense political conflicts and a pivotal moment in the Hundred-Year War – something neither Sozin nor Azulon could have achieved. The episode reached its peak when all the key players gathered in the underground caves, leading to Zuko’s life-changing choice and a near-fatal encounter between Azula and Aang. Like the iconic “Empire Strikes Back,” the villains seemingly triumphed, dramatically raising the stakes, though a glimmer of hope remained.
“The Avatar and the Fire Lord” Helped Lay the Foundation For Aang’s and Zuko’s Friendship
Season 3, Episode 6
Book Three of Avatar: The Last Airbender kept surprising fans with its flashbacks, and this time they focused on the history of Aang and Zuko’s ancestors – Fire Lord Sozin and Avatar Roku. Seeing these characters and understanding their pasts – both their successes and failures – was long awaited, and the episode “The Avatar and the Fire Lord” perfectly delivered. It was deeply moving to watch the friendship between Roku and Sozin crumble, even though their conflict felt unavoidable given the historical context.
This episode beautifully highlighted the power of friendship, showing it can be even more enduring than conflict or obligation. Despite everything, Roku still considered Sozin a friend, suggesting they would eventually right their wrongs. Aang realized that friendships aren’t limited by a single lifetime – the Avatar continues to form bonds with each new Fire Lord, and even Toph Beifong’s connection will continue with the next Avatar, Korra.
“The Day of Black Sun, Part 2: The Eclipse” Saw Fire Nation History Being Made
Season 3, Episode 11
Watching war-focused episodes is always a highlight in a show like Avatar: The Last Airbender, and I think “The Day of Black Sun, Part 2” is the best one they’ve done. It wasn’t the final victory the heroes needed just yet, but it was incredibly exciting to see Sokka and the others make so much progress with their invasion plan. They almost succeeded – they got so close – and it really felt like that pivotal moment in The Empire Strikes Back where everything gets more intense and the stakes are raised even higher.
Ozai, the Fire Lord, was a cruel ruler who led the Fire Nation further down a dark path as he tried to become the Phoenix King. However, his son, Zuko, had a different vision. Finally, viewers watched Zuko stand up to his evil father, proving he had truly changed, even redirecting Ozai’s lightning attack back at him. The episode ended with a surprising twist: Zuko chasing after Aang, seemingly wanting to help. This left audiences wondering not if Zuko would join Aang, but how, considering their complicated history.
