The comedic register of "Fullmetal Alchemist" is not static; it transforms in lockstep with the characters’ losses and the expanding scale of the conspiracy. Tracing this evolution reveals how deeply humor is embedded in the narrative's architecture.

Al cannot eat, sleep, or feel. The comedy that derives from his condition — cats nesting in his armor, villagers mistaking him for the eponymous “Fullmetal Alchemist,” his polite apologies while terrifying everyone — is rooted in a profound ache. Arakawa’s genius lies in never letting the audience forget the tragedy while allowing them to laugh at its absurd manifestations. Al’s innocence and kindness, played against his monstrous appearance, generate a situational comedy that questions what it means to be human.
