If you started Attack on Titan because of its Titans and fast-paced battles, the character story can become surprisingly difficult to follow. By Season 3, the series is no longer simply about humans surviving monsters. By Attack on Titan Season 4, the story expands into Marley, competing political interests, inherited Titan powers, and characters whose motivations are shaped by years of conflict.
This guide to Attack on Titan characters breaks down the major figures, their roles, relationships, Titan abilities, and how they change across Seasons 3 and 4. It also explains the transition from the early Scout Regiment story to the much larger conflict introduced in the Final Season.
The official series information identifies Eren, Mikasa, Armin, Levi, Hange, Reiner, Zeke, Gabi, Falco, Pieck and several other characters among the central cast of the Final Season.
Spoiler warning:
This article discusses major character developments through the ending of the anime.
The Core Attack on Titan Characters
The easiest way to understand the cast is to separate the original Paradis characters from the Marleyan characters introduced more prominently later.
Eren Yeager
Eren begins as an impulsive boy determined to destroy the Titans after witnessing the destruction caused by the Colossal Titan. His character becomes dramatically more complicated as the series progresses.
By Season 3, Eren learns that the Titans and the history of humanity are connected to secrets inside the walls. Season 4 then changes his role completely. He is no longer simply reacting to events; he begins making decisions that affect Paradis, Marley and the people closest to him.
The official Final Season material lists Eren as one of its central characters and describes him as continuing his struggle while the threat around him changes.
Mikasa Ackerman
Mikasa is one of the strongest soldiers in the Survey Corps and has a deep connection with Eren. Her exceptional combat ability is not simply a convenient plot device: her Ackerman heritage explains why she possesses extraordinary physical capabilities.
Her story becomes particularly interesting in the later seasons because her loyalty to Eren increasingly conflicts with the direction he chooses.
Armin Arlert
Armin is physically less imposing than many soldiers, but his strategic thinking repeatedly changes the outcome of battles.
His importance grows considerably after the events of Season 3. His intelligence becomes especially valuable once the conflict stops being a straightforward battle between humans and Titans.
The official character information describes Armin as a strategist whose role in the fight grows as he matures.
Levi Ackerman
Levi is one of the most capable soldiers in the series and a key member of the Survey Corps.
His fighting ability is obvious, but his real importance is broader. Levi frequently becomes the person responsible for making difficult decisions when there is no completely safe option.
Season 3 also reveals more about his connection to Kenny Ackerman, adding context to the Ackerman family.
Hange Zoë
Hange combines scientific curiosity with military responsibility. Their fascination with Titans initially provides some lighter moments, but Hange eventually becomes one of the most important leadership figures in the Survey Corps.
The Final Season’s official cast information includes Hange among the returning central characters.
Historia Reiss
Historia’s storyline is central to Season 3. Her identity, royal heritage and relationship with the Reiss family become essential to understanding how Paradis was governed.
Her development is particularly significant because she stops being merely someone protected by the Scouts and begins making decisions for herself.
Jean Kirschtein
Jean is one of the most grounded members of the original group. Unlike Eren, he does not initially dream of sacrificing everything for an ideal.
That makes Jean useful as a character through which viewers can understand the cost of war from an ordinary soldier’s perspective.
Connie Springer and Sasha Blouse
Connie and Sasha represent the more personal side of the Survey Corps. Their friendships with the other cadets make the military conflict feel less abstract.
Sasha’s personality, particularly her love of food, provides comic relief early in the story. Later events make her character more emotionally significant because they demonstrate how even seemingly small characters can become casualties of the larger conflict.
Attack on Titan Season 3 Characters and Why They Matter
Attack on Titan Season 3
is divided into two major story movements: the conflict involving the government and Historia, followed by the battle to retake Wall Maria.
The official Season 3 character information includes Eren, Mikasa, Armin, Historia, Jean, Reiner, Bertholdt, Hange, Erwin, Levi, Kenny Ackermann and Rod Reiss.
Erwin Smith
Erwin is the commander of the Survey Corps and one of the series’ most strategic leaders.
His importance in Season 3 comes from his willingness to sacrifice soldiers to uncover the truth about the world. His decisions demonstrate one of the recurring ideas of Attack on Titan: discovering the truth often comes at an enormous human cost.
Kenny Ackermann
Kenny introduces another side of the Ackerman family.
His relationship with Levi provides important information about Levi’s background while also showing how power operates within the government and underground criminal world.
Reiner Braun and Bertholdt Hoover
Reiner and Bertholdt are among the most important characters to understand before starting Season 4.
Their identities as the Armored Titan and Colossal Titan respectively fundamentally change how earlier seasons should be interpreted. Season 3’s revelations also establish the emotional foundation for the later conflict between Paradis and Marley.
Attack on Titan Season 4 Characters
Season 4 expands the cast considerably. Instead of focusing almost entirely on Paradis, the story introduces viewers to Marley and a younger generation of Warrior candidates.
The Final Season was released in multiple stages: Part 1 aired from December 2020 to March 2021, Part 2 from January to April 2022, and the concluding special versions were released in March and November 2023. The official portal lists 28 regular episodes plus the concluding special material.
Zeke Yeager
Zeke is Eren’s older half-brother and the inheritor of the Beast Titan.
His abilities and knowledge make him one of the most strategically important characters in the later story. His relationship with Eren also creates one of the series’ most complicated family dynamics.
Reiner Braun
Reiner becomes considerably more complex in Season 4.
Earlier seasons largely present him through the mystery surrounding the Armored Titan. Season 4 instead gives viewers greater access to his perspective and history in Marley.
This shift is one of the smartest structural changes in the series: a character who once appeared primarily as an enemy is given enough context for viewers to understand the pressures that shaped him.
Gabi Braun
Gabi is a young Marleyan Warrior candidate who strongly believes in Marley’s ideology at the beginning of Season 4.
Her storyline is deliberately uncomfortable because she initially sees the people of Paradis through the same propaganda that shaped her own worldview.
Her development becomes one of the clearest examples of how Attack on Titan characters can change when they encounter people they were taught to hate.
Falco Grice
Falco is another Warrior candidate and a close friend of Gabi.
Unlike Gabi, he tends to question the assumptions surrounding the conflict. His character becomes increasingly important because he represents a younger generation that has inherited a war it did not create.
Pieck Finger
Pieck inherits the Cart Titan and serves Marley as an intelligent and observant Warrior.
Her strength is not based only on physical combat. She excels at gathering information, analyzing situations and supporting larger military operations.
Porco Galliard
Porco is the inheritor of the Jaw Titan and the younger brother of Marcel Galliard.
His rivalry with Reiner provides another perspective on the Warrior system and its consequences for young Eldians.
The Nine Titans and Their Main Characters
One useful way to understand the later seasons is to connect each major Titan power with its current or former holder.
| Titan | Important Character(s) | Main Story Relevance |
|---|---|---|
| Founding Titan | Eren Yeager, Historia’s royal lineage | Central to the conflict over Eldia |
| Attack Titan | Eren Yeager, Grisha Yeager | Connected to freedom and inherited memories |
| Colossal Titan | Bertholdt, Armin | Massive destructive power |
| Armored Titan | Reiner Braun | Marleyan Warrior weapon |
| Female Titan | Annie Leonhart | Major early mystery and combatant |
| Beast Titan | Zeke Yeager | Strategic and long-range abilities |
| Jaw Titan | Marcel, Ymir, Porco, Falco | Fast and highly mobile Titan |
| Cart Titan | Pieck Finger | Endurance and military support |
| War Hammer Titan | Lara Tybur, Eren | Weapons and unusual Titan abilities |
The official Final Season cast confirms the continued presence of Eren, Reiner, Zeke, Pieck, Porco and the younger Warrior candidates in the later story.
How the Characters Change From Season 3 to Season 4
The biggest difference is not simply that the characters become older.
The entire meaning of their relationships changes.
In early seasons, the central question is essentially:
How can humanity survive the Titans?
By Season 4, the question becomes much broader:
What happens when the people you considered enemies are also human beings shaped by their own history?
That change explains why Season 4 spends substantial time with Reiner, Gabi, Falco and other Marleyan characters.
A useful viewing approach is to avoid treating the Marleyan characters as completely separate from the original cast. Their experiences mirror several themes already established on Paradis: inherited hatred, military indoctrination, family expectations and the consequences of decisions made by previous generations.
Three Details That Are Easy to Miss
The story deliberately changes whose perspective you trust
Early episodes encourage viewers to identify strongly with Eren and the Scouts. Season 4 disrupts that comfortable perspective by beginning with Marleyan characters.
This isn’t merely a change of setting. It forces the viewer to reconsider earlier events from another side.
Titan powers are also political weapons
The Titans are not simply supernatural monsters. By Season 4, they function as military assets, deterrents and symbols of national power.
That distinction helps explain why Marley invests so heavily in Warrior candidates and why the Founding Titan becomes such a major strategic objective.
The younger characters inherit an old conflict
Gabi and Falco are especially important because they did not create the conflict surrounding Eldia and Marley.
Yet they are expected to fight it.
That creates a parallel with Eren’s generation, showing how political and historical conflicts can be passed from parents to children even when the younger generation has little control over their origins.
Common Mistakes When Following the Cast
Mistake 1: Treating every Titan shifter as an independent character.
The Titan powers are inherited, so several different people can possess the same Titan across the story.
Mistake 2: Assuming Season 4 is a completely separate story.
It directly builds on revelations from Seasons 1–3.
Mistake 3: Forgetting the time jump.
The characters have changed significantly between the end of Season 3 and the beginning of the Final Season.
Mistake 4: Confusing Marleyan Warriors with ordinary Marleyan citizens.
The Warrior program has a specific military and political role.
Mistake 5: Watching Season 4 without remembering the Season 3 finale.
The discoveries made after the battle of Shiganshina are essential for understanding why the story expands beyond Paradis.

Frequently Asked Questions
Who are the main Attack on Titan characters?
The central characters include Eren Yeager, Mikasa Ackerman, Armin Arlert, Levi Ackerman, Hange Zoë, Historia Reiss, Jean Kirschtein, Reiner Braun and Zeke Yeager. Season 4 also gives major roles to Gabi Braun, Falco Grice and Pieck Finger. The official Final Season cast lists these characters among its principal performers.
Who are the main characters in Attack on Titan Season 4?
Season 4 continues the stories of Eren, Mikasa, Armin, Levi and the Survey Corps while introducing or expanding the roles of Gabi, Falco, Pieck, Porco and other Marleyan characters. Reiner and Zeke also become particularly important to the story.
What happened to the Attack on Titan characters after Season 3?
The characters enter a much larger conflict after the truth about the world outside the walls becomes known. The time jump before Season 4 changes their relationships, goals and responsibilities, while Paradis becomes directly involved in a conflict with Marley.
Is Attack on Titan Season 4 the final season?
Yes. The official Attack on Titan portal identifies Season 4 as The Final Season and records Part 1, Part 2 and the two concluding special versions.
Where can I watch Attack on Titan Season 3 and Season 4?
Streaming availability depends on your country. Current platform listings include Disney+ and Prime Video, with Prime Video’s listing showing the Final Season and a Crunchyroll trial option. Check the service available in your region before subscribing because catalogs can differ by location.
Conclusion
The appeal of Attack on Titan characters comes from how dramatically their roles evolve. Eren, Mikasa, Armin, Levi and the other original characters begin in a survival story centered on the walls, but Season 3 exposes the political and historical foundations underneath that conflict.
Season 4 then widens the perspective by introducing the Marleyan side and giving characters such as Reiner, Gabi, Falco, Zeke and Pieck much greater importance. Understanding those relationships makes the Final Season considerably easier to follow—and makes many earlier events feel different when viewed again.
For anyone starting the series or returning after a long break, keeping track of who holds each Titan, where each character comes from, and what they believe about the opposing side is the simplest way to make sense of the increasingly complex story.
