The Fiends (魔神 Majin?, Magical Race or Demons) are a collection of supernatural races descended from an evil supreme deity known as an Archfiend. The races are comprised of evil deities, demons, the undead and living monsters. They are the major antagonists in the 2004 reboot of the modern Ninja Gaiden games, and its sequels.
History of Ninja Gaiden
Before the races of Fiends, there was Vigoor, the first Archfiend, from whom all Evil Deities and Fiends arose. He was eventually defeated and banished to another dimension, by the thirtheen Divine Dragons. Not completely destroyed, Vigoor would manage to hold onto existence through the jealousy and hatred of one of the Dragons.
Time passed, until in the ancient era of human history, the Evil Deities and their fiendish minions re-emerged, due to the betrayal of the 13th Dragon, who was corrupted by Vigoor and became the Dark Dragon. Unopposed, they conquered the world and the ancient human tribes. The archaic humans were impressed by their awe striking powers, idolizing and worshipping these evil deities as gods, writing them into ancient mythologies. It was in this time when the bloodlines of the ancient human tribes were mixed with the fiends, creating a new race of fiends.
Due to their wicked nature, the evil deities eventually fought amongst themselves and with their armies vied for control of the world, while the human inhabitants were caught up in the chaos and suffered greatly. It was during this time that a new lineage of human warriors took up arms against the Fiends, they would later be known as the Dragon Lineage, who descended from the Divine Dragons themselves. With Dragon blood coursing through their veins, they fought the Fiends for tens of thousands of generations until the struggle ended when members of the Dragon Lineage were able to seal away the Evil Deities and the demonic Fiends. Ever since the Fiends have had a strong hatred towards the Dragon Lineage and their Dragon Ninja descendants.
The descendants of the ancient human tribes with strong blood ties to the Fiends lingered throughout the ages, mostly within the borders of the Vigoorian Empire, waiting for the day when the Fiends would rise again.
The Archfiends are evil supreme deities, each ruling a pantheon of deities and Fiends. They are in a constant power struggle with each other vying for complete control of the Fiend race and all the domains, mainly the underworld and earth. The omnipotent and omniscient powers of the Archfiends are far reaching, affecting the world on a universal scale, resulting in the warping of reality, time and space. During these disastrous times vortexes fill the skies as earthly and hellish realms intertwine.
- Vigoor: The original fiend, and progenitor of all the Archfiends, Greater Fiends and the lesser Fiends. It was through him that fear, hatred and evil came into existence. He is the Deity of Destruction known as Demon.
- Vazdah: The successor of Vigoor, Vazdah came into being after the defeat of Vigoor by the Divine Dragons. Vazdah rose from the physical corpse of Vigoor, and ruled during the age of myths and legends, where he was simply known as the Archfiend. He was sealed away through the use of the Demon Statue by ancestors of the Dragon Ninjas.
- The Vigoorian Emperor: The immortal figurehead and ruler of the Vigoorian Empire. It is said in a prophecy that the Vigoorian Emperor would be infused with the powers of all the Evil Deities if he were ever to be united with the Dark Dragon Blade for seven days.
- The Dark Dragon: The 13th divine Dragon who with his brethren banished Vigoor and the Evil Deities to the ends of the world. He was the youngest and weakest of the Divine Dragons, resulting in an inferiority complex that caused him to be envious towards his brethren. Over the course of the centuries, this envy turned into hatred, which Vigoor used to hold onto existence. Corrupted by Vigoor, the young dragon became a powerful being known as the Dark Dragon. He slayed his brethren and plunged the world into a total abyss of destruction, until his eventual defeat by members of the Dragon Lineage. From his bones the Fiends forged the Dark Dragon Blade, a powerful sword that grows stronger with each killing that occurs within its vicinity.
- Murai: A master ninja and leader of the Shadow Ninja Clan. He became a disciple of the Dark Dragon in pursuit of power, which lead him to manipulate even the Vigoorian Emperor. During the Dark Dragon Blade Incident, Murai obtained the fully powered Dark Dragon Blade upon the completion of his scheme. With the blade Murai infused himself with all the powers of the Dark Dragon, becoming the "Devil Incarnate".
- Dagra Dai: A philosopher who roamed the ancient earth lost in his thoughts and detached from the chaos and destruction around him. Gazing into the eyes of Vazdah after stumbling into a deep dark pit, he was infused with immense power. He awoke as the Infernal Priest Dagra Dai, and carried out his master's will with almost as much ferocity and wickedness as Vazdah. With his new powers he forced the four Greater Fiends to do his bidding, ruling over them.
- Gogohn: Known as the Supreme Fiend, he established the City of Tairon, which gave birth to the Vigoorian Empire, where he ruled for a period of time. He later roamed the earth and erected a shrine dedicated to awakening the Archfiend in South America, deep in the mountains of the Amazon jungle. He would later die there after it's construction.
The Greater Fiends are minor evil deities in a pantheon, that serve under an Archfiend. Like their masters, they are eternal and immortal, however, their powers do not extend far enough to be felt on a universal scale, but can still have devastating effects on the region they happen to occupy. Each Greater Fiend usually rules a territory with a horde of fiends at their disposal.
Humans with strong blood ties to the fiends retain their souls when turned, elevating them to the level of a Greater Fiend. Among their fellow humans they are revered as gods and goddesses.
Ancient Greater Fiends
- Ishtaros: One of the captivating goddesses who resides in the underworld. In Ancient times she was worshipped as a goddess by the ancient Babylonians, where she was responsible for mixing the bloodlines of the ancient human tribes with the fiends, creating a new race of fiends. She is the Ancient Greater Fiend of Creation.
- Nicchae: The other captivating goddess who resides in the underworld. Like Ishtaros, she played a part in mixing the bloodlines of the ancient human tribes, where she was worshipped as a goddess by the Ancient Greeks. She is the Ancient Greater Fiend of Destruction.
Vigoorian Greater Fiends

- Marbus: A devilish Greater Fiend who rules over hell and all the demonic races of fiends, rarely leaving his domain. He usually sits on his throne mocking his victims as he conjures demonic minions do his bidding. Marbus is the Archfiend of the Underworld and the one who protects the emperor.

The Fiends are supernatural beings and creatures who originally descended and spawned from the original Archfiend Vigoor. They have been recorded by ancient humans in myths, legends and folklore by cultures all over the world. Although fiends are classified by how they came into being, they can all trace their origin back to the deities who spawned them.
Fiends are divided in two categories: pure and half-blood. Pure fiends are the original fiends that descend from the Archfiends and originate from their own dimension. Half-blood fiends were once humans who transformed into a fiend because of their cursed blood; most of them are vigoorian in origin.
