===Background===
Formally, the /, a megastructure built by a sentient civilization in a distant universe by whose main purpose was the search and extraction of the necessary resources for the continuity of said civilization. Even though its creators were already extinct, Chaos's primary purpose remained unchanged and, by using 97% of its functionality, it fragmented its authorities into multiple beings, the Machine Gods, sending them to another star system to fulfill the primordial directive, remaining isolated within the boundary of its origin place.Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountainous City, The Day to Bring Down Gods, Section 18: I Am the Thunder that Smites Stars (I)
It was the sole ship carrying a designation. With the spawning of the oldest generation of Machine Gods, the Titans, Uranus inherited its position as the flagship and leader of the fleet. At some point, Kronos became the next flagship after defeating his progenitor and later, one of his descendants belonging to the next generation, would take his position after the events of the Titanomachia.Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountainous City, The Day to Bring Down Gods, Section 1: Interstellar Mountainous City, OlympusFate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountainous City, The Day to Bring Down Gods, Section 16: Souls To Be Equals in Due Course (III)

===Personality===
It is portrayed as a being that holds no particular feelings towards mankind, being unable to perceive them due to its scale. It's a machine that prioritizes its main directive over everything else to the point of trying to turn part of the planet into fuel in order to maintain its fleet and resume the interstellar journey.
==Role==
===Fate/Grand Order===
====Olympus: Interstellar Mountain City====
Following Zeus' core destruction, an enormous rift appears in the sky from which Chaos emerges. Ares, shaken and surprised that it has survived in such narrow space, recognizes it as the source of the Twelve Machine Gods. In a reflex act, Chaos fires an arrow of light, effortless disintegrating Ares, who was fast enough to react and protect Chaldea using his own body. After Quirinus confirms the identity of the being as the god who is one with the void of time-space, Chaldea's party tries to find the reason for its sudden appearance. Europa assumes it is due to Zeus' will to proceed with his main plan, but then she discards said possibility because, while Zeus wanted to live to preserve the Earth's culture, Chaos' utmost priority is maintaining the fleet by harvesting the planet's resources to embark once again in an interstellar voyage.
The god starts the countdown for the resource collection. If it isn't stopped, 37% of the planet's mass will be turned into spiritrons and the planet won't be able to recover itself from the colossal damage. Ritsuka proposes to fight Chaos, but Holmes comments that it's impossible due to the distance between them and the god, apart of the danger of using heroic spirits in unknown territory such as within the spatial rift. Musashi asks Holmes if the machine gods differ from the conceptual gods, to which he replies that, while they have differences, both preside over natural phenomena. Hearing this, Musashi states that although she didn't have a chance before Zeus, she can defeat Chaos: What exists beyond the fissure cannot be affected, but while that eye is looking down at the reality, there is a "path". She does not have to defeat the eye, but to close the "window" from which the eye is gazing upon the Lostbelt. While Holmes reminds her the spatial cervice is the void itself, Musashi insists the reason she is in the Atlantic Lostbelt is to cut through the void and reach beyond zero. After agreeing with Chaldea, Musashi rides the Storm Border to head for the rift.

Even at its maximum speed, Storm Border is unable to reach Chaos because, although they have visual confirmation, the instruments have problems measuring the correct distance. Captain suggests using the Zero Sail to shorten the distance, but Quirinus tells them it won't be necessary: ​​he will create a direct path using his authority. Close to the rift, Chaos fires an arrow of light at the Border, which is intercepted by Nemo's multiple spiritron beams as Musashi prepares her Noble Phantasm. Once ready, she cuts the "path" between Chaos and reality, successfully forcing it to return to its original place.
==Abilities==
Chaos is the Colossal Interstellar mothership, the Spherical Space-Time Fortress. In Greek Mythology, Chaos is the largest and most Ancient God of all. A supernatural deity that spent 97% of his resources to send Gaia and the other Machine Gods to another universe, only for him to later become one with the gaps of that Universe's Space-Time. As a Machine God, Chaos is still a conceptual god born from deified natural phenomena. While they are fundamentally different from natural gods, they still function as gods who preside over nature and various phenomena. Chaos resembles a , a theoretical construct of an artificial structure designed to completely cover a star in order to make use of its energy. The massive shell that makes up his colossal body uses a star from an ancient, distant system for its core. In terms of sheer scale, this god of the heavens far surpasses the entire planet Earth, making him a god that embodies every concept and natural phenomenon under the sun. Sherlock Holmes claims that even that fails to do it justice. Even Magical Energy on par with Goetia's Bands of Light that burned away Human History would be unable to destroy Chaos. However, U-Olga Marie's Third-Planetary Class Saint Graph output was stated to be "second only" to Goetia, implying her vessel in Olympus surpassed even Chaos' current one.Fate/Grand Order: Cosmos in the Lostbelt - Hell Realm Mandala, Heiankyo - Flash of Roaring Thunder - Prologue
Chaos perceives the universe on a vastly greater scale than Zeus. Just like Zeus couldn't tell individual Humans appart, the same way humans can't differenciate ants,Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountainous City, The Day to Bring Down Gods, Section 9: Thou Art the Ardor that Corrupts the Stars (II) Europa speculates that Chaos is not aware of Grand Lancer Romulus-Quirinus, Ares, and the rest of Chaldea. The attack that killed Ares was more akin to a reflex. During the battle against Chaos, Goredolf Musik stated that he was the most terrifying enemy they had faced.
===Combat===

After Zeus's demise, Chaos was able to synchronize with the Kronos Crown, which gave him access to the Authority of Machine Gods that no longer exist. This allowed him to fire a ray of sunlight with a great Authority that even exceeds that of Apollo in his prime. Thanks to the beam traveling , out of all the characters that helped defeat Zeus, only Grand Lancer Romulus-Quirinus and Ares were able to react in time. While Quirinus put up a Bounded Field to protect Caenis, Miyamoto Musashi, Europa, and the rest of Chaldea, Ares used his own body, a set of armor made of Holy Adamant Steel and reinforced with conceptual defense to block the attack. While Ares succeeded in doing so, his Saint Graph was vaporized instantly, leaving no trace of his body behind. Captain Nemo states that while the Nautilus might not be as strong as Poseidon, with the Nautilus, the Shadow Border, and Hephaestus's power all helping them out, the Storm Border can give him a run for his money. While using 120% of their combined power, the Storm Border's Spiritron cannon was able to block multiple beam attacks from Chaos, protecting Musashi so that she could perform her ultimate attack.
The Kronos Crown also gave Chaos the capability to disassemble everything on Earth, physically and conceptually, into their component Spiritrons. He would absorb not just Olympus, but every resource in the planet's surface, from organisms, to life, to electromagnetic signals, to soil, to Mystery, to even abstract concepts, so as to resume his voyage across the sea of stars. This would consume 37% of the planet's volume, regressing its surface to its primordial state. 
Chaos manifested through a rift in space at least twenty thousand meters above Olympus. Sherlock Holmes states that even if they reached him, they would have to fight him inside that rift. He says that a fight in outer space is uncharted territory even for Heroic Spirits, and that even if there was a spacefaring Heroic Spirit, the battle would be over by the time they were to reach Chaos. While the Storm Border moves at 27,000 km/h, their sensors are still unable to register Chaos. This is because Chaos's body is surrounded by a three-dimensional puzzle, which makes it nigh-impossible for anyone to cross the distance between them in a straight line. Initially, Captain Nemo says that they wouldn't be able to reach Chaos even in a million years. Thanks to the Paper Moon acting as their compass they can get closer to him little by little, however, Leonardo da Vinci explains that it would take 62 hours times 672 attempts to reach him. Although Grand Lancer Romulus-Quirinus had been saving all the power left in his body to fight the Alien God, he decided to use all his remaining Divine aura, Authority, and Magical Energy to create a path for the Storm Border reach Chaos's past his Cross-Dimensional Maze.Fate/Grand Order: Cosmos in the Lostbelt - Olympus: Interstellar Mountainous City, The Day to Bring Down Gods, Section 23: The Day to Bring Down Gods Being able to move in a straight line, the Storm Border would be able to cross the 2000 meters left between them under 3 minutes, piercing through several layers of space acting as a Bounded Field.
===Noble Phantasm===
Having synchronized with the Kronos Crown, Chaos gained access to World Discipline Keraunos. This allowed him to create a Space-Time quake, and open a rift in space with which he could reach Olympus. While Miyamoto Musashi might not have been able to defeat Zeus on her own, she realized she could take down Chaos. She didn't need to destroy him, but to simply close the "window" Chaos was looking through to observe the Atlantic Lostbelt, a hollow space equivalent to a "Void". By reaching to a realm beyond "Zero", Musashi achieved "True Emptiness", 「」, and was able to cut "Void", successfully sealed Chaos from this universe at the cost of her life, wiping herself from existence, removing herself from the Throne of Heroes and preventing her from being re-summoned.
