+A **fatal flaw** refers to an inherent weakness or vulnerability that inevitably leads to the downfall or destruction of an entity, system, or character. It is often a subtle yet critical defect, capable of undermining even the greatest strengths. This inherent imperfection can be seen as a core element in [Tragedy](/wiki/tragedy) and a driving force in many narratives, where a hero's own [Hubris](/wiki/hubris) might become their ultimate undoing.
