Azula’s Ruthless Takeover of Ba Sing Se Is the Most Devastating Moment in Netflix’s ‘Avatar’ Season 2

The second season of Netflix’s live-action ‘Avatar: The Last Airbender‘ has officially dropped, and it delivers a gut punch that fans of the original animated series will feel deep in their bones. The fall of Ba Sing Se is finally here in live-action, and it hits harder than almost anyone was prepared for.

By the time the credits roll on the season finale, Ba Sing Se has fallen, the Fire Nation is in control, Iroh is imprisoned, Aang’s fate hangs in the balance, and Team Avatar has suffered its greatest defeat yet. For viewers only now discovering this world, the scale of what just happened cannot be overstated.

How the Fire Nation Seized Ba Sing Se

The groundwork for Ba Sing Se’s collapse was laid long before any Fire Nation soldier set foot inside its walls. Aang and Team Avatar uncover a conspiracy within Ba Sing Se involving Long Feng (Chin Han) and the king’s guard, known as the Dai Li, and attempt to expose it to King Kuei (Justin Chien), who seems to care little about politics and appears annoyed at being pulled away from his gardening.

The Cultural Minister of the kingdom, Long Feng, is the one indirectly controlling every aspect of the city, including governance, administration, and security.

With a ruler who refuses to engage with the war raging outside his walls, the city is ripe for infiltration from within rather than conquest from without.

In a meeting with Long Feng, Azula kills all of Ba Sing Se’s highest-ranking men in the force when they question why the Fire Nation wants to control the city. Long Feng, however, begrudgingly but fearfully complies with Azula’s plan to raise Ba Sing Se’s drawbridge and let the Fire Nation troops roll in. The most impenetrable city in the world never required breaching. It simply needed one crack of fear at the top.

Princess Azula Controls Ba Sing Se by the Finale

Princess Azula (Elizabeth Yu) seizes control of Ba Sing Se, with the Azula-controlled Dai Li parading through the center of the city in a chilling display of Fire Nation dominance. The secret police that once served to keep Ba Sing Se’s residents in deliberate ignorance now march under enemy command.

Azula taking Ba Sing Se for the Fire Nation is the single most impactful moment in the entire Hundred Year War. Ba Sing Se was an impenetrable fortress and the last bastion of the entire Earth Kingdom. With the Air Nomads gone for a century, the Water Tribes devastated, and now this, there is very little standing in Fire Lord Ozai’s way to world domination.

Production designer Michael Wylie and his team built Ba Sing Se as a full outdoor practical set on a back lot, with executive producer Christine Boylan describing the decision as central to the season’s tonal step-up. The grandeur of watching that hand-built world fall to the Fire Nation makes the defeat sting all the more. This is a season that earned every moment of its heartbreak.

The Avatar State and Aang’s Uncertain Fate

Aang’s response to the city falling around him is one of the season’s most visually spectacular sequences. After a lot of intense bending and fighting, Aang taps into what can best be described as an “Avatar portal,” seeing physical forms of all the Avatars that came before him in his mind’s eye, causing his eyes and head arrow to turn a shining blue as he channels their collective power through his body.

When it appears his friends are about to lose, Aang enters the powerful Avatar State and nearly defeats Azula. However, he ultimately chooses mercy over killing her, and Azula uses the opportunity to strike him down while he is in the Avatar State, which is a potentially catastrophic event that could end the Avatar cycle forever. It is a moment of compassion that costs everything.

That lightning bolt from Azula didn’t just seem fatal, it actually was. Aang temporarily died, but Katara brought him back to life using the water from the Northern Water Tribe’s Spirit Oasis that she obtained in Season 1. However, the Netflix version makes a significant departure from the original animated series, with the show showing that Katara’s healing waters haven’t worked, leaving Aang’s fate ambiguous. It is a bold creative choice that raises the emotional stakes considerably heading into the already-confirmed final season.

Zuko’s Redemption Derailed

Nowhere is the season’s emotional wreckage more complex than in Zuko’s story. Haunted by memories of his abusive father, Fire Lord Ozai (Daniel Dae Kim), and inspired by the compassion and love of his Uncle Iroh (Paul Sun-Hyung Lee), Zuko increasingly chooses to help others rather than serve the Fire Nation.

While living in Ba Sing Se, he lives modestly, defends vulnerable Fire Nation refugees, forms an unexpected bond with Katara, and even apologizes for the suffering his family caused hers.

In the climactic battle, he aligns with his sister against Team Avatar as the Fire Nation seizes control of the city. Rather than completing his redemption arc, Zuko ends the season caught between the person he wants to become and the family legacy he had wanted to escape. It is a regression that will frustrate and fascinate viewers in equal measure.

Katara’s words during the final confrontation, “I thought you had changed,” are met with Zuko’s reply of “I have changed,” making the betrayal land with full dramatic weight. Whether Zuko truly believes his own words is the question the show wants audiences to sit with.

What the Fall of Ba Sing Se Sets Up for Season 3

Season 3 isn’t just confirmed, it’s already been shot. Seasons 2 and 3 were filmed back-to-back after Netflix committed to telling the full Avatar story in March 2024, two weeks after the release of the first season. That continuity of production suggests the creative team has a clear and deliberate vision for where all of this devastation leads.

The obvious first step Season 3 will have to take is resolving Aang’s injuries at Azula’s hand. Beyond Aang’s survival, there is Iroh’s imprisonment, Zuko’s fractured soul, and the question of whether an Earth Kingdom without Ba Sing Se can mount any meaningful resistance against Ozai’s empire.

Every character has been pushed to a breaking point, every alliance tested, and every belief shattered. With Aang unconscious, Zuko’s soul split in two, Iroh in chains, and the Earth Kingdom’s greatest city under Fire Nation rule, the groundwork laid in Season 2 makes the final chapter feel genuinely earned rather than manufactured. The show has finally matched the animated series at its most emotionally ambitious.

Whether you think Azula’s takeover was inevitable or whether you believe there was a moment when Ba Sing Se could have been saved, drop your thoughts in the comments, because this ending is going to be debated by ‘Avatar’ fans for a long time.
