Definition of archfiend in English:
A chief fiend, especially the Devil.
- We are going to that castle over there, and striking a deal with the resident archfiend to make sure that they don't escape.
- The background makes it fun to pick your favorite archfiends, and easy to work up a ‘reason’ for the battle… I like the idea of exploring the politics of Hell.
- Bands of angels and archangels follow the divine leader, while troops of demons and archfiends hasten after the evil lord.
