Attack on Titan is a dark fantasy anime based on the manga by Hajime Isayama, first aired in 2013.
The story is set in a world where humanity lives inside enormous walled cities to protect themselves from terrifying, man-eating giants known as Titans. For over a century, these walls have kept humanity safe—until one day, a colossal Titan breaches the outer wall, leading to catastrophe.
The series follows Eren Yeager, his adopted sister Mikasa Ackerman, and their friend Armin Arlert, who survive this devastating attack. Traumatized by witnessing the death of his mother at the hands of Titans, Eren vows to wipe them all out. The trio joins the Survey Corps, an elite military unit that ventures outside the walls to fight Titans and uncover the truth about their existence.
Eren Yeager is a determined, hot-headed young soldier driven by his deep hatred of Titans after witnessing his mother’s death. Initially fueled by a simple desire for revenge and freedom, Eren later becomes the wielder of the Attack Titan and learns shocking truths about the world. Over time, his fierce resolve transforms into a complex, often ruthless determination to secure freedom for his people—no matter the cost.
Reiner Braun is a strong, stoic, and conflicted warrior who serves as a soldier in the Scout Regiment while secretly being the Armored Titan, an infiltrator sent from Marley to destroy humanity inside the walls. Struggling with intense guilt and a fractured sense of identity, Reiner is torn between his duty as a warrior and the bonds he forms with his comrades, making him one of the series’ most tragic and complex characters.
Levi Ackerman, often called Captain Levi, is humanity’s strongest soldier and a squad captain in the Survey Corps. Known for his incredible speed, skill, and calm precision in battle against Titans, Levi is stoic, blunt, and seemingly cold, but deeply loyal to his comrades and driven by a strong sense of duty. Beneath his tough exterior, he cares deeply about protecting humanity and honoring the sacrifices of those he’s lost.
Armin Arlert is a thoughtful, gentle, and intelligent member of the Survey Corps and one of Eren Yeager’s closest childhood friends. Though physically weaker and often self-doubting, Armin’s sharp mind, creativity, and strategic brilliance make him an invaluable asset in humanity’s fight against the Titans. Deeply idealistic, he dreams of seeing the world beyond the walls and believes in fighting for freedom and hope, even in the darkest times.

Beneath her calm exterior, she is driven by her unwavering love and need to protect Eren.
Grisha Yeager is Eren Yeager’s father, a determined and secretive man who played a key role in the series’ deeper mysteries.

After coming to Paradis Island, he became a respected doctor and secretly passed on the power of the Attack Titan to his son, believing Eren would carry out his mission. Grisha’s past and choices profoundly shape the story’s events and Eren’s fate.
Hange Zoë is the brilliant, eccentric, and passionate leader of the Survey Corps’ research division, later becoming the group’s commander.

Zeke Yeager, also known as the Beast Titan, is a calm, intelligent, and cunning warrior from Marley. The older half-brother of Eren Yeager, Zeke possesses royal blood and plays a key role in the conflict over the Titans' power. Though he presents himself as composed and rational, his actions are driven by a tragic past and a radical plan to “save” the world by ending the cycle of hatred—even at a terrible cost.
