Ouroboria

**Ouroboria** (ウロボリア *Uroboria*) is one of Gate of Nightmares' main antagonists. He is a cruel & eccentric scientist, and part of Moongarde's Five Saints.

## Appearance

Ouroboria is a tall man with grayish skin and wild purple hair. He hides his eyes with black tinted glasses and wears a metallic chin guard.

His clothes consist of a black and golden coat, brown gloves, gray pants with a scale pattern and black shoes. His Star Magic Gem is triangular and fixed to his collar.

A gray Ouroboros is floating behind him.

## Personality

Ouroboria is a very eccentric individual, as seen with his movements, his voice and his way of speaking.

He is a cruel scientist who sees Nightmares as nothing but mere tools or weapons. Due to his ruthless nature, he has no qualms about hurting Nightmares or forcibly merging them to create biological weapons.

Ouroboria also shows a great deal of arrogance when confronted with people he considers weaker than himself. But at the same time, he is careful and cautious around stronger opponents. Instead of fighting Esteo head-on, he rather flee the scene.

## Synopsis

### Game

#### Forest of Spirits Arc

Ouroboria first appears during Azel's Nightwalker test. After Azel and Emma beat up two Moongarde soldiers, Emma is worried that this might cause an international conflict. Ouroboria then descends from the sky, proclaiming that this incident won't cause any trouble, as no one will ever hear of it. He goes on to introduce himself, while summoning a huge snake-like Nightmare to kill the two Nightwalkers. Azel and Emma are left to fight the gigantic snake all alone, while Ouroboria watches from the side.

Ouroboria is surprised to see that they actually managed to defeat the Nightmare. However he isn't worried in the slightest and simply laughs, as this fight allowed him to gather lots of useful data. He paralyzes Azel and Emma and prepares to kill them with his own hands, but Esteo and Abigail appear to defuse the situation. Esteo threatens Ouroboria, who then decides to leave, as he didn't find what he needs and "Shion is itching to take over anyway". Somewhere else in the forest, he calls someone to hand his mission over to Shion. He then returns to his research tower in Logania.

#### Zahardia Arc

Later, during Team Azel's confrontation with Doga, he reveals that Ouroboria is the mastermind behind the dark cloud over Zahardia. However, the cloud is not the reason the Nightmares went rogue. The cloud was only used to gather data about the Halflings.

#### Oruha Island Arc

The group later meets Ouroboria again at Oruha Island's Everstone. After Meruru's vision, he appears together with Rachel to take the Everstone's power. Ouroboria laughs as he realizes that Emma is Rachel's sister. But Rachel doesn't care. She takes the Everstone's power, turns around and tells Ouroboria to take care of the situation. He is also surprised about this turn of events, but accepts, while Rachel leaves the cave.

As the group is left alone with Ouroboria, he laughs and holds a lengthy monologue. To kill Azel and the others, he brought a special test subject. The fruits of his years-long research, Gigantia, the "Ultimate Hybrid Nightmare". He explains that Gigantia is a biological weapon, capable of destroying entire armies by itself. The group trembles in fear as they are confronted with the huge spider-like Nightmare. However, both Azel and Michi notice Gigantia's cries of pain. They realize that Ouroboria created this monster by forcefully merging multiple other Nightmares. To end its misery, they decide to fight against Gigantia.

After they managed to defeat Gigantia, Ouroboria shows the same reaction as last time. He is surprised, but laughs about the new research data he was able to gather. Again, he tries to kill Azel and the others, as Esteo and Abigial aren't here to help. The group gathers all of their courage and confront Ouroboria in one big final battle.

They are ultimately able to defeat Ouroboria, who begins to caugh and laugh maniacally. Purple smoke is forming around him, as he realizes that he is dying. He starts laughing again and shouts how interesting this experience is. He falls to the ground, but suddenly a blue light takes control of him. Ouroboria jolts up and proclaims "This world is coming to an end", the same words Meruru said after she woke up. Ouroboria then falls dead to the ground. Azel and the others become silent and hope that Gigantia can now rest in peace .

King Logan uses Ouroboria's death as a reason to declare war on Estrea.
