- "My anger, pain and sadness—shall be your loss."

The Dark Knight is characterized by wearing tight, sometimes enclosed black armor and wielding a sword steeped in wicked powers. Their physical stats, with exception of Defense, are usually high, but their other stats depend on the game they appear in. The typical Dark Knight ability is Souleater, also known as Darkness, which allows them to sacrifice their HP to perform stronger attacks.
However, Souleater is not exclusive to the Dark Knight class. Dark Knights may also have abilities based on Blood Equipment that allows them to absorb HP and MP from enemies. The Dark Knight is opposed by the Paladin, holy knights who protect allies and wield sacred powers. Unlike many classes, Dark Knights bear a signature weapon, the Deathbringer, which has a chance to kill certain enemies in a single blow.

The Magic Knight's appearance is nearly identical to later games' Dark Knights, and in fact they were explicitly called as such in the English version of the DS remake. They can wield dark blades, and in the NES release cast low-level White Magic. In the DS release, they instead use the Souleater ability, trademark of the Dark Knight, which damages all enemies at the cost of some of one's health.
Cecil Harvey is the primary protagonist of the game, and serves as a Dark Knight until he becomes a Paladin. Baron is also mentioned to have a battalion of Dark Knights in their army, but due to the intense training many Dark Knights fail to master the dark sword and lose their minds in the process. A reflection of Cecil's Dark Knight is fought as a boss. The King of Baron is also a dark knight.
As a Dark Knight, Cecil can use the Darkness ability to inflict damage to all enemies at the cost of some of his HP. In the DS version, Darkness doubles his attack for three turns at the cost of 10% of his maximum HP per attack.
As in Final Fantasy IV, Cecil's dark side is fought as a boss. Cecil is also seen as a Dark Knight in several flashbacks.

Dark knights, also known as black knights, were a minority group of knights that refused to serve lords or kings. Instead they either looted and raided, hunted bounties, or lived off the charity from the more humble folk.
As they had no master, and thus no squire, they would paint their armor their signature black color to prevent rust and damage. Dark knights were considered by many a necessary evil, as they would protect the villages and lesser people from invaders and bandits, but would cause many problems in the regions that they dwell in to keep themselves alive and well.
