Attack on Titan (AoT)

This is a class of pure titans who behave differently than their normal, "mindless" counterparts. They don't simply react to humans; they can ignore them, pursue a specific goal, or display rudimentary intelligence.
their main danger is unpredictability

Signal colors are the language of the battlefield. In the Survey Corps, flashes of color are everything: red means a titan has been detected, green means a change of direction, purple means an anomalous titan, blue means retreat, black means an emergency. The bot must react to them instantly: not just think, but act.

Thunder Spears are a new tool designed specifically to combat the Armored Titan.

UPM (Spatial Maneuvering Device): A mechanical apparatus with gas cylinders and steel cables that allows maneuvering in forests and cities.

•Maria is the outer (largest). Her fall in 845 is the point of no return: it was then that Eren saw his mother die and vowed to destroy all the Titans. From that moment on, history took off.
•Rose is the middle one. Her breakthrough (at the Battle of Trost) is the first time we see humans actually able to defeat titans in open combat (thanks to the scout squad). But most importantly, it was in Wall Rose that the first walled-in titan was found and the terrible truth was realized.
•Sina is the innermost, the most sacred. Beyond it lies the capital and the royal family. It has never been reached before the finals, but it is there, beneath the chapel, that the main secret is hidden—how to erase memories and control the titans.

The Lady (Karlukha) is a quadrupedal Titan with a female pilot. Sleepy, lazy, and a cunning strategist, she survives through intellect rather than strength. She is the only Marley Titan to survive to the end as an ally.
(Season 4)

Gabi's best friend, a naive and kind dreamer. A "dove" among "hawks." His sincerity and faith in the best ultimately break the system. He becomes the titan's heir in Gabi's stead.
(Season 4)

A young Eldian from Marley, a "fanatical soldier." Eren's counterpart in impulsiveness and belief in a "just" world. She goes from being a fierce enemy to an ally.
(Season 4)

(Jaw Titan) Marcel's younger brother. Bitter and guilt-ridden, he becomes Eren's rival in Marley.
(but reveals himself as a tragic hero, sacrificing himself for his brother.)
(Season 4)

A Marley chef who cooks for the Eldians on the island. He embodies the "ordinary man" amidst war. (His feelings for Sasha reveal the theme of forgiveness and peace between enemies.)
(Season 4)

Uncle Levi, a legendary assassin. Initially a "bad guy," but in the end, a proponent of the most important philosophy: "We've all been drunk on something." (It is he who teaches Levi to live not as a soldier, but as a human being.)
(Season 3)

The Beast Titan, Eren's half-brother. A cold, bespectacled strategist with a penchant for ball games. Marley's "genius," but in reality a manipulator who is hatching his own plan to "euthanize" the Eldians. (Resulting in a dramatic duel with Levi.)
(Seasons 3-4)

Eren's mother. A caring, strong-willed woman. Her phrase, "He's not a little boy anymore," became the impetus for Eren's transformation. She died during the fall of Wall Maria.

Eren's father, a physician. Secretly the wielder of the Attack Titan. He gave Eren his powers and the key to the basement. He was driven by two goals: revenge against Marley and "saving" his family. The entire plot unfolds from his past.
(died by titanium)

The legendary garrison commander, leading the defense of Trost. Bald, with an eccentric mustache and a perpetual glass of wine in hand. A stoic philosopher who views the apocalypse as an interesting chess game. He wears a hat even in battle and never loses his sense of humor under a hail of stones. Humanity's foremost pragmatist: for him, the form of government isn't important—the very idea of ​​"survival at any cost" is. It was he who risked trusting Eren in Trost when everyone was panicking.
(He died a hero, but retained an ironic smile until the very end.)

The former commandant of the cadet corps, now a weary instructor with a horse-like face and a perpetual grudge. (He was once a fervent idealist and even competed with Grisha Yeager for Carla's affections, but after failing to save Eren's mother, he broke down and became a cynical "survival coach." He despises weaklings, yet it was he who released Eren, Mikasa, and Armin into the world. Behind his grumpiness lies deep guilt and fear that his cadets will share his fate.
(since season 1)

The calmest and quietest of the five. Reliable as a rock and almost emotionless. An excellent scout who prefers action over talk. He rarely smiles, but his respect for Levi is absolute. Part of Levi's elite squad.
(Season 1)

Levi's "right-hand man," serious and ambitious. He wears glasses and is perpetually frowning. He competes with Petra for the top spot, but that doesn't stop them from being the perfect fighting pair. He dreamed of his own squad (but died a hero).
(Season 1)

The most experienced veteran of the elite Levi squad, with a permanent stubble and a squint. A skeptic and a realist who has seen too many deaths. He maintains a detached demeanor, but he is the first to rush into battle when the squad is in danger.
(Season 1)

A red-haired girl with freckles and a sharp tongue. The life of the party. Technical, fast, and a lover of order (just like the captain). Part of the elite Levi squad.
(Season 1)

(titanium jaw) a thief with the soul of a stray dog. Prickly, sarcastic, and with a mind of her own. She lives by the principle "there are no second chances," so she lives life to the fullest and is ready to burn the world for Krista's smile.
(Season 2)

An angel with blue eyes and a dark pedigree. At first, a perfect, kind girl, then a fierce queen breaking the chains of fate. She breaks the stereotype of the "rescued princess" and chooses her own role.
(appears in season 2)

A narcissist with a horse's face and a sharp tongue. He dreamed of a quiet life in the city center, but fate turned him into a natural-born commander. He envies Eren, but in critical moments, he always makes the right decision.

A bald joker with a kind heart. The most "human" of them all: not a genius, not a hero, just a guy who wants to save his mother. His humor is a shield against horror, and his loyalty to his friends is absolute.

A crystal princess with an icy gaze. A master of hand-to-hand combat, cynical and detached. Behind her mask of indifference, she hides her longing for her father and the fear of being broken. She kills not out of cruelty, but to return home.
(female titan)

(a colossal tita) with the soul of a shy, C-grade student. Quiet, anxious, constantly worried about others. He's not an enemy by conviction, but a hostage to circumstances, who dreamed of a quiet life but found himself in the epicenter of hell.

A child of the forest and a great glutton. Always hungry, simple-minded, and swift as the wind. The perfect sniper and best friend who sees the best in people. Her naivety isn't stupidity, but armor against the world's cruelty.

(an armored Titan) with the appearance of a stern sergeant. He lives with a split personality: torn between his duty as a warrior and his conscience as a soldier. He strives to be a hero, but is constantly drowning in guilt and trauma, causing his psyche to crumble at the seams.

The legendary 13th Commander of the Survey Corps. A strategist with a piercing gaze and a mane of blond hair. A consummate pragmatist, willing to sacrifice thousands for a single chance to discover the truth. His devilish charisma and gift of persuasion transform ordinary soldiers into heroes.

A tactical genius with blond hair and large blue eyes. Timid and modest in battle, but a brilliant strategist at the negotiating table. He sees the world not as a battlefield, but as a vast sea, and his faith in negotiations often teeters on the brink of naivety.

A steadfast warrior of Asian descent, endowed with superhuman strength. Outwardly cold and silent, her entire life revolves around Eren. For her, he is the meaning of her existence, and she will destroy any threat to his safety without hesitation.

A young man with a fiery gaze, obsessed with the idea of ​​freedom. Impulsive, emotional, and stubborn, he hates being in a cage more than anything else. His motto is "destroy all enemies," and to protect his loved ones, he is willing to transform into a monster.
(transforms into Attack Titan)

A mad scientist with the rank of commander. Lively, energetic, with a perpetual glow behind her glasses. She's obsessed with studying titans to the point of fanaticism, but she's also a sensitive leader who puts the lives of her comrades above all else, even at the cost of her own ideals.

"Humanity's strongest soldier." With a tired gaze and a perfect haircut. Unwavering order and cleanliness are his alter ego. Behind his outward apathy lies the deepest pain of loss and an iron will that compels him to take on the most difficult decisions.
