Unseen Chaos Physiology (Final Fantasy)

==Summary==
Chaos/Unseen Chaos (カオス? or 混沌, Kaosu) is a reoccurring storyline element in the "Fabula Nova Crystallis" mythos of Final Fantasy. This substance originates from a place known as The Unseen Realm, where there is no concept of Space-Time and Form, perfect chaos. Chaos is also omnipresent across various dimensions and timelines. It's the blessing of the goddess Etro that was granted to mankind in the form of both Hearts and Souls, which acts as the very idea of fundamental existence. However, it is also dangerous because if unbound, it would turn the physical world into a timeless realm.

|-|Hearts=
*Incorporeality and Abstract Existence (Type 1): Chaos is the source of all creation and acts as the fundamental force that that makes the worlds complete. Which includes creating one's "Heart" and "Soul". The Soul acts as the very idea of someone and defines all of existence itself, which can extend to one's mind, and information. The Heart acts as its "Warehouse" and is linked to the Soul. Of which is confirmed to not be material.
*Higher-Dimensional Existence: The Soul returns to the Unseen Realm upon the death of the Physical Body, a realm that is described to be beyond all timelines and dimensions. This would include the world of Valhalla, which is confirmed by WOG to exist on a different plane of reality, where the entire Cosmology can be seen, with all timelines and dimensions being referred to as the "Lowerworld" in nature. The Void Beyond is stated to harbor Extradimensional spaces, in comparison to all timelines of the Historia Crux, which are 4-D, yet is still inferior to the world of Valhalla, being referred to as it's "Shadow". The Soul is created from Chaos, of which paradoxes are a side effect, a phenomenon stated to transcend time. Implying that Chaos and by extension, the Soul is superior to it. The "Heart" acts as its warehouse and is linked to the soul, meaning this should apply to the Heart as well.
*Time Travel and Dimensional Travel: Those who have an affinity for Chaos can utilize time gates to travel into a Dimension called the "Historia Crux" which connects to every timeline in Final Fantasy XIII.
*Precognition and Retrocognition (Divination; Non-Combat Applicable): Those with Chaos can utilize the Eyes of Etro which can have visions across every period which can even work on people with Acausality (Types 4 and 2), as seen with characters having visions of others despite the Chaos in their Hearts and Souls. 
*Sealing, Summoning, and Animal Manipulation: Controlling Monsters is done by sealing defeated foes into crystals and calling them forth into battle when necessary. However, the enemy must be in a defeated/vulnerable state to seal.
*Extrasensory Perception: People with abundant chaos in their hearts are sensitive to things others miss: such as the prophecies of the seeress, the voices of the dead, and are drawn to both the visible and invisible worlds, while other beings are tied only to one world with the other being inaccessible. Characters are also able to detect when others are present by their "Hearts".
*Cosmic Awareness: Through the use of the Eyes of Etro, Serah was able to witness Lightning and Caius' fight in Valhalla, as well as Noel's arrival through the Historia Crux.
Weaknesses: Every time someone uses the "Eyes of Etro", their lifespan greatly shortens. Lost and Fragmented Hearts can cause one to lose their sense of emotion with no recollection beyond the memories of them.
|-|Souls/Phantomas=
*Same as Hearts plus Unconventional Immortality (Types 1, 4, 5, 6, 8, and 9): When a human dies, their soul turns into crystal energy and returns to the unseen realm, passing through Etro's Gate to be reborn anew. The Unseen Realm lies beyond even Valhalla. This is stated by WOG to exist on a different plane of reality, where the entire Cosmology can be seen, with all timelines and dimensions (4-D) being referred to as the "Lowerworld" in nature. The soul is also eternal and can exist as long as people in the living remember them, even going as far as to use other bodies to house their souls such as Lumina being the vessel for Sarah's soul, and Rem and Machina are also able to pass on their phantoma to various members of Class Zero. It's stated that whatever Chaos infects loses its life, death, and time.
*Acausality (Types 2 and 4): Chaos originates from The Unseen Realm, which along with the Visible World, Valhalla and Etro's Gate operate on different Concepts of Space-Time and Form ranging from it being Non-Existent to it being ambiguous. It's also an energy source that resides within all humans' Hearts and Souls, which can defy the laws of the physical world. This also extends to the Void Beyond which includes the realm of Serendipity, a place locked in an "Eternal Now", where the past and future do not exist, only the present. A "Paradox" is created by having the past and future overlap with one another, creating a new present. 
*Regeneration (Mid-Godly): No longer under Bhunivelze's control. Various characters were able to reform their bodies from their souls in a matter of seconds, the Soul is confirmed to be one's concept.
*Nonexistence Physiology (Nature Type 3; Aspect Types 1, 2, 3, 4, and 5): The soul is both everything and nothing with beings that exist in their astral form simultaneously exist and don't exist. The soul is also made of and infused with Chaos which have different concepts of Space-Time and form, ranging from being ambiguous to being Non-Existent. The soul is confirmed to be one's conceptual being that defines all aspects of existence including fragments which are nuggets of pure information. As well as Orhpan's Cradle, which is an entire reality made of data. The Chaos is stated to be able to both overwrite and destroy timelines across the past, while also having the past and future intersect with one to create a paradox, lacking a "True History". The first human, Paddra Nsu-Yuel had become one with Chaos, is said to have disappeared from the pages of history. Lumina calls the place inside Lightning's mind something akin to an "Unseen Realm", which is Non-Existent in nature. This is supported by Kanna's L'Cie stone crystal which states that she tapped deep into her consciousnesses and called upon the incredible, otherworldly power hidden in the furthest depths of the abyss of nonexistence.
*Beyond-Dimensional Existence (Type 1): The Soul is infused with Chaos which originates from the Unseen Realm where the Concepts of Space-Time and Form are Non-Existent in nature. The Unseen Realm lies beyond all existing timelines and dimensions, being completely inaccessible by normal means. This includes The Visible World, The Historia Crux, The Spiral, The Void Beyond, and Valhalla where the Concepts of Space-Time and Form differ from being Ambiguous to being Non-Existent. The Void Beyond is said to harbor "Extradimensional spaces" in comparison to all of the existing timelines within the Historia Crux. The Void Beyond exists a part of, yet is also stated to be lower than the world of "Valhalla", being referred to as it's "shadow". Valhalla, in particular is stated by WOG to exist on a different plane of reality, where the entire Cosmology can be seen, with all timelines and dimensions, which include the Void Beyond's Extradimensional spaces, being referred to as the "Lowerworld" in nature. Valhalla is also stated numerous times to be beyond Space-Time. Paradoxes are a side effect of Chaos which is stated to transcend time, implying Chaos' ontological superiority.
*Nonduality (Type 2): The Soul is infused with Chaos which exists across all timelines and dimensions. Chaos existed before the creation of the world and is said to embody both everything and nothing, which even extends to minor dualities such as existence and nonexistence, which include characters that exist between "Dream and Reality"
*Resistance to Spatial Manipulation and Time Manipulation: The Heart and Soul are infused with Chaos, and can traverse places that have varying different concepts of Space-Time and Form ranging from being ambiguous to being Non-Existent. Chaos is also stated to cause someone to lose their time.
*Resistance to Perception Manipulation: Souls can traverse through Valhalla to get to the unseen realm where Etro resides. Valhalla is stated to distort one's senses.
*Resistance to Age Manipulation: Chaos can alter human biology to stop the aging process altogether.
*Resistance to Power Nullification and Limited Resistance to Power Modification and Power Absorption: Scaled from Class Zero who can draw power from their Phantoma's to act as their energy source instead of The Crystals. Rendering the crystal jammer and jammer fields, which severe one's connection to the crystals to utilize magic uselessly, and cannot be nullified, modified, or absorbed without being able to affect the Phantoma itself. Which in turn requires being able to interact with Chaos itself.
*Unconventional Resistance to Soul Manipulation, Conceptual Manipulation (Type 1), and BFR: Characters such as Snow Villiers, Noel Kriess, Rem, and Machina have shown to be able to "live" without possessing their own souls/phantomas. While The Savior can forcefully remove someone's soul from their body, if one has strong enough willpower however, the Soul cannot forcefully be removed from the body to go into Yggdrasil to be stored for the new world, unless that person is freed from the darkness in their Heart, which is why Lightning wasn't able to initially save Snow's soul.
*Resistance to Chaos: Civilians of Nova Crysalia and Orience have shown to naturally stand around Chaos without succumbing to its effects, and party characters from Final Fantasy XIII and Type-0 have fought other characters who utilize the power of Chaos. Hearts and Souls are also naturally infused with Chaos.
*Weakness to Memory Manipulation: If the memory of one's existence is wiped clean from the minds of those who knew them, it can destroy a Soul/Phantoma.
*Weakness: If a Soul/Phantoma is weakened enough, it can cause an incurable illness that will eventually kill the person. As seen with Rem Tokimiya.

All previous abilities in addition to the following:
</tabber>
Note: The "Eyes of Etro" shortening a person's lifespan does not apply in places devoid of time. However, should someone utilize the eyes of etro numerous times in Timeless Voids, it will catch up to the person when entering a place where time is normal, as seen with Serah.
Note 2: Resistance to Age Manipulation only applies during the events of Lightning Returns, as such this does not apply to the Type-0 cast
Note 3: While the "Soul" is immortal, the body isn't. The body can and will eventually die of natural causes. Only by the time of Lightning Returns does the body itself become immortal.
