Dark Nightmare

Dark Nightmare (ダーク・ナイトメアー) is the overarching main antagonist of the Kindred Hearts series. It is the villainous deity of the Espers' multiversal home world (a.k.a Earth/Real World), with Juno and the Espers as its nemesis.

## Appearance

Dark Nightmare is a demonic being with a shadowy black body, a pair of flaring red eyes and horns on his eyebrows. He has a dark grey skin with red vein-like markings on it, as well as spiky black protrusions on his shoulders. His true form is a gigantic skeletal dragon-like being. In this form, he can destroy anything he sees and even infect living things into Deviants, his monstrous demon-like minions. Despite being a deity, Dark Nightmare is able to spawn lower/weaker versions of himself asexually, such as Scarlet Raven (which took Alfredo's appearance upon possessing the Esper boy during his early ages and awakened later after the death of his parents) and the Revenant (the one that destroyed Afilia eons ago). He could also produce cells that allows him to infect Espers into Deviants, which caused an outbreak within Polaris Sanctuary during the events of Omega Fury.

## Personality

Dark Nightmare is a deity bent on destruction, darkness, hatred and even death. He despises everything that is good, including creation and justice. His aim is to cover the Real World in total darkness and rule it within his claws, but Juno kept thwarting his plans and even waged several wars against him. He is also willing to grant people powers by turning them into Deviants, and he also loved being worshipped too (the Kamiyama and Iwakura clans worshipped Dark Nightmare for power and glory). Dark Nightmare is weak to Juno and her attribute, Light. He even shudders and succumbs at the sight of one of her Transcendents, like Yurika and Izana. A Transcendent's prayer is never left unanswered, and one can re-seal Dark Nightmare at will, though he can be defeated permanently by a certain someone.

## Trivia

* Dark Nightmare is referred as Yomi by the Kurihara clan, whilst Juno is referred as Amaterasu. Archaic scriptures refered Dark Nightmare as Beelzebub and Asmodeus.
* Dark Nightmare is inspired by Giff from Kamen Rider Revice, Generalissimo of Badan from Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat.

* Dark Nightmare has a goal of his own and only uses his worshippers as tools and nothing more. It is evident on the end of the Zero arc where he killed Shinzo Kamiyama, his devout worshipper after his purpose was finished. He cannot be trusted whatsoever.
* Dark Nightmare has been sealed permanently. He was already sealed multiple times by Juno and her forces, and once by Alfredo at the end of the Zero arc. Despite being a deity, Dark Nightmare is mortal, though he could only die by being slain by someone chosen by Juno.
