Attack on Titan Character FAQs

Who is the strongest character in Attack on Titan?

Levi Ackerman is consistently depicted as the strongest individual soldier, possessing unmatched blade skills and tactical awareness that allow him to eliminate Titans efficiently. However, Bertholdt's Colossal Titan form represents raw destructive power far exceeding any human fighter. The answer depends on context—pure combat mastery versus destructive capability yield different results. Eren's evolving abilities throughout the series eventually rival these contenders.

What is the main antagonist's goal?

The primary antagonistic force involves Titans themselves, initially presented as mindless creatures. Gradually, the narrative reveals intelligent Titan shifters like Annie, Reiner, and Bertholdt who infiltrated humanity for specific purposes. Their true motivations involve reclaiming something precious and addressing perceived wrongs. Later revelations introduce more complex antagonistic perspectives that challenge initial good-versus-evil frameworks.

Does Mikasa end up with Eren?

The romantic relationship between Mikasa and Eren remains complicated and unresolved through most of the series. Mikasa harbors clear romantic feelings toward Eren, while his responses remain ambiguous and often dismissive. Their bond emphasizes emotional connection and shared history rather than traditional romance. The series prioritizes plot developments and character growth over traditional romantic conclusions.

What are Titans and where do they come from?

Titans are massive humanoid creatures that consume humans apparently without reason or purpose. Initially, humanity believes them to be mindless natural disasters. As the story progresses, viewers discover that certain Titans possess intelligence and the ability to transform into human form, suggesting artificial origins. The true nature of Titans and their creation involves humanity's own history and experimentation.

Can humans become Titans?

Yes, certain humans possess an ability to transform into Titan form, though this remains extremely rare. Annie, Reiner, Bertholdt, and Eren all demonstrate this capability, though their origins and motivations differ. The transformation process appears both voluntary and involuntary depending on circumstances. This power represents a significant strategic advantage and carries severe psychological consequences for those who possess it.

What happened to Eren's mother?

Eren's mother was eaten by a Titan during an early attack that breached humanity's outermost wall. This traumatic event fundamentally drives Eren's obsession with destroying all Titans and his initial enlistment. The circumstances surrounding her death, combined with his father's mysterious absence, fuel questions about hidden conspiracies. This tragedy shapes virtually every major decision Eren makes throughout the series.
