Would the words nemesis and enemy be considered synonyms or antonyms?

The Words "nemesis" and "enemy" are generally considered synonyms, as they both refer to adversarial figures or forces. However, "nemesis" often implies a more profound, destiny-driven opposition, frequently associated with retribution or poetic justice, while "enemy" is more straightforward, simply denoting someone who opposes or is hostile to another. Thus, although they share similar meanings, the nuance of "nemesis" gives it a distinct character.
