7 Essential Attack on Titan Episodes That Changed the Anime Forever, Ranked

by

Attack on Titan is famous for its surprising plot twists, and its most impactful episodes often completely change the direction of the story. These episodes are packed with action and suspense, but they also cleverly develop the characters and expand the world in interesting ways. It’s a difficult balance to strike, but the show’s best episodes pull it off flawlessly.

Some chapters of this series are truly remarkable and stand out for their significant impact. While many are excellent, a few are particularly strong due to their scale, animation, or memorable character interactions. Here’s my ranking of the most important chapters, from the one that reveals why Eren is the central figure to the one that brings the story to a close.

7) “I Can Hear His Heartbeat: The Struggle for Trost, Part 4”

Season 1, Episode 8

One of the most important discoveries in Attack on Titan is that Eren Yeager has the ability to transform into the Attack Titan. This is a turning point that drives the entire story forward, allowing for the development of the Nine Titans lore, Eren’s role as a powerful weapon, and ultimately, his devastating actions. Because of this, the episode “I Can Hear His Heartbeat: The Struggle for Trost, Part 4” is crucial – it confirms that the mysterious Titan appearing during the attack is actually Eren. This reveal is particularly impactful because the audience, along with the characters, had been led to believe he was gone.

This episode is memorable for more than just Eren’s surprising turn. It’s packed with moments like Armin’s clever planning – hinting at his future growth – and the recruits’ thrilling battle at headquarters, keeping viewers on the edge of their seats. However, even with all the action and revelations, it doesn’t quite reach the intensity of later, pivotal episodes. Considering Attack on Titan consistently improves with each story arc, that’s not unexpected.

6) “Warrior”

Season 2, Episode 6

The ‘Warrior’ arc in Attack on Titan is famous for a shocking betrayal: the reveal that Reiner and Bertolt are actually the Armored and Colossal Titans. This discovery shatters the Scouts Regiment’s trust and makes the conflict more emotionally impactful, giving the villains more depth and understandable motivations. It also establishes the intense rivalry between Eren and Reiner, which becomes a central conflict throughout the series. Overall, it’s a genuinely surprising and memorable part of the anime.

This episode of Attack on Titan is among the series’ strongest, thanks to its incredible animation, powerful music, and emotional impact. While it starts a little slow, the episode ultimately delivers some of the show’s best moments. The production quality is a significant step up from the first season, though it doesn’t quite reach the scale of the most intense battles later in the series.

5) “Midnight Sun”

Season 3, Episode 18

Although earlier episodes are more immediately exciting, the events in Attack on Titan Season 3’s “Midnight Sun” are ultimately more important for the story. The episode forces Levi to make a heartbreaking decision: save Commander Erwin or Armin. He chooses to save Armin, leaving the Scouts without their leader and, many believe, setting the stage for Eren’s actions later on. This episode also marks the deaths of Bertolt and the turning point for Floch Foster, while giving Armin the immense power of the Colossal Titan. All of these events have a lasting and substantial impact on the rest of the series.

Even though the fighting has stopped, “Midnight Sun” is a powerfully emotional part of Attack on Titan. After three seasons, it’s easy to get invested in the characters and feel the impact of this chapter. It’s more compelling than episodes like “I Can Hear His Heartbeat: The Struggle for Trost, Part 4” and “Warrior,” but doesn’t quite reach the level of episodes that combine intense action with major story twists.

4) “Scream”

Season 2, Episode 12

The final battle of Attack on Titan Season 2 is amazing, but the most crucial moment happens in Episode 12, “Scream.” That’s when we discover Eren can control ordinary Titans, but only if he’s touched someone with royal blood. This revelation is key to the events of the Rumbling and makes Eren a much more powerful and dangerous character. It also firmly establishes the tragic direction of the anime, giving Eren the ability – and a heartbreaking motive, fueled by Hannes’ death – to do things previously unimaginable.

The scene where the Titan that killed Eren’s mother also kills Hannes is powerfully tragic and beautifully fitting. Everything surrounding that moment is incredibly gripping – Ymir’s internal struggle, Commander Erwin’s determination in battle, and the near-death experience of Eren and Mikasa. It’s a masterclass in building suspense and developing characters, and it still feels impactful every time I watch it.

3) “From You, 2000 Years Ago”

Season 4, Episode 21

Following the intense episodes “Two Brothers” and “Memories of the Future,” “From You, 2000 Years Ago” marks a clear turning point in Attack on Titan, establishing Eren as the antagonist. This episode shows Eren cleverly manipulating Zeke and then connecting with the Founder, Ymir. Reaching Ymir is a pivotal moment, giving him the power to destroy the world beyond Paradis. The episode delves into Ymir’s tragic past, revealing how the Titans were originally exploited and emphasizing the ongoing cycle of violence. Her story directly explains and justifies Eren’s current actions.

The finale of “From You, 2000 Years Ago” is a major turning point, solidifying its place among the best episodes of Attack on Titan. Seeing the Wall finally fall after so many seasons is incredibly impactful. The characters’ dawning horror at how far Eren has gone is devastating, and Eren’s final speech is truly unsettling. Combined with incredible animation and acting, this episode represents one of the series’ highest achievements.

2) “Assault”

Season 4, Episode 7

While ‘From You, 2000 Years Ago’ feels like the moment Eren truly becomes a villain, hints of this shift appear much earlier, especially in the beginning of Season 4. Eren starts a war with Marley, harming innocent people to achieve his aims, and drags the Survey Corps into it, forcing them to compromise their values. This is clear in the ‘Assault’ episode, where they aid Eren even though they don’t fully agree with his plans – a sign of the conflict to come. ‘Assault’ also flips the script, presenting the show’s heroes in a potentially villainous light for the first time, and reinforces the series’ central idea that violence only leads to more violence, setting the stage for everything that happens later.

This episode marks a significant shift in the story, even if it’s not the most crucial moment in the anime. It’s incredibly intense and packed with non-stop action that’s often difficult to watch. The episode carries a lot of emotional weight, from Armin’s devastating actions to Jean’s difficult decision. While it’s one of the anime’s most emotionally challenging installments, that’s also what makes it so powerful. The stunning animation and voice acting further enhance the impact of every scene.

1) “The Final Chapters: Special 2”

Season 4, Episode 30

The final episode of Attack on Titan is surprisingly impactful, even though it’s the end of the story. It reframes the entire series, solidifying its tragic nature – something that still felt open to a happier ending earlier on. The finale clarifies the motivations behind Eren’s choices, though it doesn’t justify them. This new understanding makes the whole series worth revisiting. It’s a smart conclusion, despite a few minor flaws.

Placing the final episode of Attack on Titan at the top of this list might be a bold choice, but it’s both incredibly well-made and vitally important to the story. The episode is treated like a full-length movie, giving viewers over an hour of stunning animation and satisfying conclusions to character arcs. While the ending won’t appeal to everyone, it’s expertly crafted and feels right for the series. In fact, just the opening sequence is better than most episodes in terms of overall quality.
