Thanatos

**Thanatos**(タナトス) is one of the four Goddess of Deus Ex Machina as well as their leader and the strongest of the quartet. This makes her the main antagonist of the Deus Ex Machina Saga. After being defeated by Hida Kizuna, her consciousness was transferred into the body of Hida Nayuta, becoming **Hida Setsuna** in the process.

## Appearance

Thanatos has golden blonde hair and blue eyes. She has a well-endowed body and is considered to be overwhelmingly beautiful, like a work of art. She wore white one-piece dress which reveals most of her cleavage.

In her full form, she looks similar yet somehow different from her fellow goddesses. Her arms and legs are covered by a mechanical exoskeleton armor with a mix of white, blue and golden color and wings grow from the back and golden halo resembling sun above her head.

## Personality

Thanatos is very complicated. Despite being a creator of both Lemuria and Atlantis, she views them as a mere experiment as well as her residents and has no problem sacrificing them for her goal. Despite restoring Genesis to the surprise of her followers, she still views all as a failure and destroys them along with Atlantis in the process. Thanatos is also melancholic as she can't understand the feelings of others either from other Machine gods or humans which is seen when she kills Kizuna and was unable to understand him and others' sadness and their anger on her. Despite that, Thanatos also has emotion as she was surprised by Kizuna's power and later shown even fear after he manages to injure her.

## Background

Unlike the other members of Deus Ex Machina, Thanatos wasn't born a mortal. She was a computer program to self evolve by her creators (implied to be human researchers). Her ultimate goal is to reach perfection, establish the laws of the universe and be the foundation of order. However, upon reaching that state, which is a Machine God, she no longer remembered how and why she was created. Thus began her endless search for her purpose which eventually led to her fateful encounter of Osiris, the first being closest to her existence. Together they formed the Deus Ex Machina with different goals, Osiris, to revive her family and planet and Thanatos to find the purpose behind her existence. Along the course of the goddesses' pursuits, they created several worlds, including Atlantis and Lemuria.

## Plot

### **Vatlantis Arc**

Following the defeat of Nayuta, the Deus Ex Machina have descended from the skies and met Kizuna and his allies who are perplexed to see them. Thanatos the first to reply to Kizuna's question by claiming all four of them, including herself, are Goddesses that shocks nearly everyone. While being told about Kizuna to be "responsible" for this sudden change, Thanatos deems such event that resulting the resonance of Core from another world to be beyond their expectations while aiming at the destroyed Genesis which she suspects that Vatlantis was attempting to create a world similar to them. When Kizuna calls them out for erasing the world of Vatlantis, the only response Thanatos ever gave is that its their "responsibility" to eradicate the "failed works" and using her powers to wipe out Zeltis within a flash. In spite of the best efforts from Kizuna and Aines, they're powerless against Thanatos as not even their best attacks are affecting her or her fellow Goddesses, which Thanatos reveals that the Core are also their creations. Thanatos is attacked by Kizuna but she easily blocks his attacks.

## Skills and Abilities

As the leader of the Deus Ex Machina and a true goddess, Thanatos is the most powerful from her group and possessed godly power different from even the other machine gods. She stated that only those who also have the power of a machine god are able to at least fight her. This was proven true when Reiri, Hayuru, Yurishia, Gravel, and Syliva were unable to do anything to her, even though they had done Harem Hybrid before arriving. The former machine gods were able to at least hold Thanatos back, despite not having the same level power they had before and were borrowing power from Nayuta.

* **Immense Durability:** Similar to Odin, Thanatos possesses tremendous durability but to an even greater degree as only her fellow goddesses or those with the power of God can injure her. The combined power and effort of the rest of Amaterasu Reiri, Gravel, and Grace were unable to deal with a any damage to her and even Hokuto who gained some of her power back was unable to hurt her.

She was able effortlessly defeated Reiri, Gravel, Hayuru, Yurishia, Sylvia, and Hyakurath with her Keraunus and her law control power. She was also able to easily overpower weaken Hokuto. Thanatos's fighting style is focused od eliminating her enemies without giving them any means of opposing her, making anything they do against her useless without affecting her own attacks.

## Equipment

## Trivia

* She's the one of the only characters to appear on a volume cover who had never done anything sexual with Kizuna, same as Odin. She is also the only member of the Deus Ex Machina who had never been affected by Kizuna's Reincarnation abilities. This is likely because Thanatos was always a god, therefore, couldn't be affected.
	+ Thanatos is also the only Machine god who isn't smiling on a volume cover.
