—In-game description from Fire Emblem Echoes: Shadows of Valentia.
The Fiend (魔人 Majin, lit. Devil or Demon Man) is an enemy-only Monster class that first appeared in Fire Emblem Gaiden, and reappears in its remake. It is an enemy-only monster variation of the Baron class and in Gaiden shared the same stats with the Baron Class. In Echoes, they have different stats and are now marked as Great Terrors.
