Doppelganger

A doppelganger is a double, counterpart, or uncanny duplicate of a character, whether physically identical, strongly resembling, or structurally parallel. It may externalize conflict, identity, fear, or possibility, but it does not necessarily represent a dark self or foretell downfall.

A doppelganger mirrors or duplicates another character closely enough to make identity and difference central. Compare the pair's resemblance and divergence, then explain what the doubling reveals rather than assuming the double is automatically evil.

Nara meets a traveler with her face, memories, and one decision she never made.
The duplicate shares identity markers but embodies an alternative life choice.

Common confusion

Doppelganger vs. Foil

A doppelganger depends on doubling; a Foil depends on illuminating contrast. One character pair can serve both functions.

Doppelganger

The counterpart closely duplicates or mirrors identity.

“She meets a traveler with her face and memories.”

Foil

Focused contrast makes another character's traits clearer.

“Two heirs answer the same crisis differently.”
