Final answer:
The archetype that primarily affects change in others without undergoing significant personal change is the Catalyst. Archetypes are original models for various narrative elements, including characters like the trickster or femme fatale. The Tragic Hero is an archetype that experiences internal change and leads to the audience's catharsis, unlike the Catalyst.
Step-by-step explanation:
The archetype that acts heroically but does not change much themselves, yet has the ability to change others, is known as a Catalyst. The Catalyst is a character that brings about transformation in other characters without undergoing a significant change themselves. This type of hero can inspire, push, or in some cases, provoke others to face their challenges, evolve, or transcend their flaws. Unlike the Tragic Hero, who exhibits a positive personality trait that transforms into a flaw resulting in their downfall, the Catalyst typically remains constant in their nature.
In storytelling, archetypes are original models or patterns of characters that are imitated in various narratives. They provide a universal language that everyone can recognize regardless of cultural background. One can think of an archetype as the original mold from which similar characters are derived. Examples of popular archetypes include the trickster figure, such as Coyote or Brer Rabbit, the femme fatale, like Pandora, and the object-based archetype like the forbidden fruit from the Garden of Eden.
According to Aristotle's definition, a Tragic Hero, like Oedipus or Creon, is a character who is fundamentally virtuous but is flawed by an inherent weakness, or hamartia, that ultimately leads to their downfall through a series of events including anagnorisis and catharsis. This archetype differs from the Catalyst in that a Tragic Hero undergoes a significant internal transformation and elicits an emotional response from the audience.
