You think you know the Survey Corps? Think again. Most fans only scratch the surface of these characters. Behind every blade swing and Titan roar hides a story that will break your heart and blow your mind.
I have spent years dissecting this series. Today, I am handing you the ultimate insider breakdown of the attack on titan characters that matter most. No fluff. No filler. Just the raw, emotional, and statistical truth about the soldiers you love and the enemies you fear.
The Holy Trinity: Eren, Mikasa, and Armin
These three childhood friends form the beating heart of the entire saga. Their bond is beautiful, but it is also the source of the most devastating tragedy in modern anime.
Eren Yeager: The Freedom Fighter Turned Monster
Eren starts as a loud, angry kid who wants to see the ocean. He ends as a global threat who shakes the very foundations of the world. His transformation is not sudden; it is a slow, painful slide into darkness driven by future memories and a desperate love for his friends.
What makes Eren so compelling is his raw honesty. He admits he is not a hero. He admits his desire for freedom is selfish. That level of self-awareness makes his descent into the Rumbling even more terrifying.
Mikasa Ackerman: The Blade of Loyalty
Mikasa is often reduced to “the girl who loves Eren.” That is a massive disservice to her character. As an Ackerman, she possesses superhuman strength and battle instincts that rival Levi himself.
Her journey is about breaking free from the obsession that defined her existence. The moment she finally makes her own choice—one that shatters her heart but saves the world—is the single most powerful scene in the entire series.
Armin Arlert: The Brain Behind the Blade
Armin proves that intelligence is a weapon sharper than any sword. While Eren and Mikasa fight with their bodies, Armin fights with his mind. He is the one who discovers the Female Titan’s identity. He is the one who sacrifices his own humanity to become the Colossal Titan.
His strategic genius saves the Survey Corps countless times. Without Armin, humanity would have fallen long before the truth about the walls ever came to light.
Levi Ackerman: Humanity’s Strongest Soldier
Levi is not just popular; he is a phenomenon. In a recent global fan poll, Levi Ackerman secured the top spot with 1,511 ELO points, beating out Eren and Mikasa. But why is a side character so beloved?
The Tragic Backstory That Shaped a Killer
Levi grew up in the Underground City, a place of filth, poverty, and violence. His mother died when he was young. He survived on scraps before being taken in by Kenny Ackerman, a serial killer who taught him how to fight and then abandoned him.
This brutal upbringing explains everything about Levi. His obsession with cleanliness is a rebellion against the dirt of his childhood.
The Cost of Being the Strongest
Levi’s strength is a curse. The deaths of his original squad—Petra, Oluo, Eld, and Gunther—haunt him. He carries their memory with every kill he makes.
His final confrontation with Eren is heartbreaking. Levi does not want to kill his former student. He does it because he made a promise to Erwin, and Levi never breaks a promise.
The Titan Shifters: Power and Curse Combined
The Nine Titans are the most dangerous weapons in the world. But the humans who inherit them are victims as much as they are monsters.
Reiner Braun: The Man Who Could Not Die
Reiner is the ultimate survivor. He is the Armored Titan, but his armor is nothing compared to his will to live. He suffers from severe mental trauma, splitting his personality to cope with the guilt of his actions.
Every time Reiner tries to end his life, his body refuses to let him die. His existence is a living hell, yet he keeps fighting. That resilience makes him one of the most fascinating characters in the series.
Annie Leonhart: The Frozen Warrior
Annie is the Female Titan. But beneath that icy exterior is a young girl who just wants to go home to her father.
Her decision to encase herself in crystal for years is not an act of cowardice. It is an act of self-preservation. Annie knows that if she fights, she will lose herself. Her eventual return in the final season is a masterclass in quiet redemption.
Pieck Finger: The Unlikely Hero
Pieck is the Cart Titan. She spends most of the series as a quadrupedal beast, but her intelligence is unmatched. She is the one who uncovers the truth about Zeke’s betrayal. She is the one who saves the Warriors countless times.
What makes Pieck special is her loyalty. She fights because she wants to protect her comrades. That simple, pure motivation makes her one of the most admirable characters in the entire story.
Attack on Titan Characters: Full Comparison Table
Here is a complete side-by-side breakdown of the seven main attack on titan characters covered in this guide.
| Character | Age (850) | Height | Titan Power | Role | Status |
| Eren Yeager | 15 | 170 cm | Attack / Founding | Protagonist | Deceased |
| Mikasa Ackerman | 15 | 170 cm | None | Elite Soldier | Alive |
| Armin Arlert | 15 | 163 cm | Colossal (later) | Strategist | Alive |
| Levi Ackerman | 30+ | 160 cm | None | Captain | Alive |
| Reiner Braun | 17 | 185 cm | Armored | Warrior | Alive |
| Annie Leonhart | 16 | 153 cm | Female | Warrior | Alive |
| Pieck Finger | ~21 | 155 cm | Cart | Warrior | Alive |
Data sourced from official character guides and fan wikis.
This table reveals something fascinating. Levi, the strongest soldier, is the shortest male character on this list. Eren, the protagonist, is not even close to being the tallest or oldest. The series consistently subverts expectations, proving that power comes from within, not from physical stature.
Power Ranking Table: Who Actually Wins?
Numbers tell a story, but combat ability tells the real truth. Here is how these seven fighters stack up in a raw power ranking based on feats, Titan abilities, and on-screen victories.
| Rank | Character | Combat Style | Strongest Feat | Threat Level |
| 1 | Eren Yeager | Titan transformation | Triggered the Rumbling | Extreme |
| 2 | Levi Ackerman | ODM blades | Defeated the Beast Titan solo | Extreme |
| 3 | Mikasa Ackerman | ODM blades | Killed Eren to end the Rumbling | Very High |
| 4 | Reiner Braun | Armored Titan | Survived countless fatal blows | High |
| 5 | Annie Leonhart | Female Titan | Beat Levi’s squad alone | High |
| 6 | Pieck Finger | Cart Titan | Outsmarted Zeke’s plans | Medium |
| 7 | Armin Arlert | Colossal Titan | Nuked the Marleyan port | Medium |
Levi may be the strongest human, but Eren’s Founding Titan form puts him in a different league entirely. Mikasa sits in a unique spot as the only person who could stop Eren when it mattered most.
Reiner, Annie, and Pieck are not just villains; they are soldiers with feats that rival the heroes. That balance is exactly why the battles feel so tense.
Final Verdict: Why These Characters Matter
They are mirrors reflecting our own fears, desires, and capacity for both good and evil. Eren shows us how love can turn into destruction. Armin shows us that brains beat brawn.
If you take one thing away from this article, let it be this: the best characters are not the ones with the coolest powers. They are the ones who make you question your own morality. That is why Attack on Titan will be remembered for decades.
