The Dark Warriors are an incompetent group of villains previously defeated by the Light Warriors. Their base of operations is the Temple of Fiends and have attempted to attack Corneria Castle on at least two occasions.
The Dark Warriors are later told for the media to be the ones who defeated Chaos by White Mage, who was intent on not having the Light Warriors steal the glory (of herself and other three healers, no less) after all the death and damage they caused.
Main article: Garland
Garland was the first Dark Warrior. He created the group alongside Bikke after the two of them were defeated at the hands of scurvy and/or the Light Warriors. He is an ex-military leader of Corneria and capable of a wide repertoire of skills ranging from cooking to summoning a Deep One.
Main article: Bikke
BIkke was the second Dark Warrior to appear. He is a horribly incompetent and treacherous Pirate. He is arguably the MOST inept Dark Warrior even when compared to Vilbert (who tried to LARP with the Light Warriors instead of fighting) and Garland (who decided to give the Light Warriors snacks after locking them up). He is both illiterate and unable to count.
Main article: Drizz'l
Drizz'l is a master of kenshido and the dark elf prince. He is the son of Astos and commands giant spiders. He joined the Dark Warriors after he was nearly slain by the Light Warriors and was promptly mugged.
Main article: Vilbert von Vampire
Vilbert is a roleplaying vampire who is somehow the son of Lich. He joined the Dark Warriors after being recruited by Garland
Honorary Dark Warriors
At one point, Princess Sara was offered the position of fourth Dark Warrior by Drizz'l, although she simply laughed at the idea, deeming them pathetic.
After Vilbert's defeat, there were many discussions on the Nuklear Power Forums concerning who would be the fourth Dark Warrior. Besides Vilbert, there were various theories including Dr. Malpractice, the Sulk, Princess Sara, King Steve, one of the "real" Light Warriors, Ranger, Berserker, and Kary.
Given the many differences and effective reversals in the role of characters in comparison to Final Fantasy (Elves and Dwarves hating each other, Matoya attempting to poison the "heroes" to get them to help, etc.) one could assume that the "Light Warriors" are actually the true villains while the "Dark Warriors" are the true heroes.
During the Light Warriors' return to the Temple of Fiends, Black Mage Evilwizardington betrayed his teammates and replaced Drizz'l (the leader of the Dark Warriors at the time).
