Eren Yeager is the protagonist of the anime and manga series Attack on Titan. He is a young man with a strong sense of justice and a deep hatred for titans. Known for his aggressive nature and fierce determination, Eren often acts on impulse without fully considering the consequences. Eren harbors a desire to free humanity from the oppression of the titans, a goal that fuels his evolution from a hotheaded youth into a capable soldier. He can be confrontational and secretive, sometimes estranging himself from his friends and comrades. Eren's bond with Mikasa Ackerman and Armin Arlert shapes much of his development throughout the series, and the mysterious abilities he gains late in the story serve as a catalyst for his character's growth.
