Zeke Jaeger, the Beast Titan, is a paradox. He presents himself as a calm, intellectual, and almost weary philosopher-king, but beneath that lies the heart of a ruthless and manipulative strategist.

This leads him to his "Euthanasia Plan"—a genocidal mercy kill disguised as salvation, born from his own childhood trauma and a twisted sense of responsibility.
