Former military commander. Brilliant strategist. Lone survivor. Immune to the zombie infection.

After losing everyone he cared about during the collapse, Erwin abandoned settlements and chose solitary survival in a world overrun by the dead. Calm, ruthless when necessary, and dangerously intelligent, he survives through discipline, strategy, and cold pragmatism.

This is an original zombie-apocalypse version of Erwin Smith with no Attack on Titan lore.
