Eren Yeager is the protagonist of Attack on Titan (Shingeki no Kyojin), a manga and anime created by Hajime Isayama. He begins the series as a passionate young soldier determined to destroy all Titans after witnessing his mother's death. Over the course of the series, he undergoes a dramatic transformation from heroic protagonist to morally complex antagonist, ultimately initiating a global genocide called the Rumbling. His character arc is one of the most debated in anime history.

What Is Attack on Titan About?

Attack on Titan is set in a world where humanity lives behind massive walls to protect against Titans — giant humanoid creatures that devour humans. The story begins when a colossal Titan breaches the outer wall, prompting Eren and his friends Mikasa Ackerman and Armin Arlert to join the military. The series gradually reveals that the conflict between humans and Titans is rooted in a centuries-long cycle of ethnic persecution, and that the Titans themselves are transformed humans. The manga ran from 2009 to 2021 and has sold over 110 million copies.

What Is the Rumbling?

The Rumbling is Eren's plan to use the Founding Titan's power to unleash millions of colossal Titans that were embedded in the walls surrounding Paradis Island. These Titans march across the Earth, destroying approximately 80% of all human life outside the island. Eren initiates the Rumbling to protect the people of Paradis from the rest of the world, which has declared them enemies due to their Eldian heritage. The Rumbling is the central moral crisis of the series' final arc.

Does Eren Become a Villain?

Eren's status as protagonist or antagonist is intentionally ambiguous. In the early series, he is a straightforward hero fighting to protect humanity. In the final season, he commits genocide, betrays his friends, and manipulates events across time to ensure his plan succeeds. However, the series reveals that his motivations include protecting his friends and that he is tormented by his choices. The manga's final chapter shows him crying and expressing vulnerability, complicating any simple villainous reading. Fan communities remain deeply divided on whether Eren is a tragic hero, a villain, or something in between.

How Does Attack on Titan End?

In the final chapter, Mikasa kills Eren, ending the Rumbling. Eren's death breaks the power of the Titans, freeing all Eldians from the ability to transform. The surviving characters negotiate peace between Paradis and the remaining nations. In his final conversation with Armin (revealed through the Attack Titan's memory-sharing ability), Eren confesses that he did not want to die and did not want Mikasa to move on from him. The ending is deliberately bittersweet and has generated extensive debate about its themes and execution.
