The Dark Players are a group of optional bosses encountered in Epic Battle Fantasy 4. They are evil undead versions of playable characters found on the final areas of the Battle Mountain, which makes them exclusive the the Steam release of the game and the Premium Pack.
As their names suggest, the Dark Players are sinister, evil counterparts of the playable characters. They all have reddish-brown skin and black eyes with tiny red pupils, giving them an undead appearance. They wear black-and-red versions of their counterparts' clothes, and wield a dark-based weapon, though with changed properties. Dark Players can also use Limit Breaks, which are charged upon receiving damage.
The are encountered right before the summit of the Battle Mountain, in a dark chamber filled with what appears to be evil spirits. The cave is initially pitch-black, similarly to some parts of the Crystal Caverns, but after defeating each of the dark beings another torch may be accessed and lit with the Candle. Only after dealing with all four Dark Players and lighting all torches entrance to the next area will open, as well as an additional chest will be revealed.
At the summit of Battle Mountain, the Dark Players may be encountered again, this time in the Dark Player Marathon, a two-wave challenge which pits the player's party against two of them at the same time.
There are four Dark Players, each acting as a counterpart to one of the playable characters. Their properties and fighting style are roughly based on the original character; for example, Dark Matt is a powerful warrior with high physical attack and defence but relatively weak magical abilities.
Defeating each of the Dark Players on Epic difficulty will award the player with their respective medal, and beating the Dark Player Marathon on Epic will additionally reward the player with "Dark Boss Rush" medal.
- Each Dark Player always drops one Bottled Darkness and one additional item upon defeat.
- Dark Players are currently the only foes to have a Limit Break bar, a feature otherwise unique to playable characters.
