Heart (Kingdom Hearts)

==Summary==
A heart is the metaphysical and abstract aspect of every existent being, being made of light and/or darkness, while also originating from aspects like memories, emotions and bonds of friendship or negative emotions. A heart defines the existence and being of someone, and can be compared to the western meaning of a soul in terms of use, even if separate.

–What is the definition of a heart in Kingdom Hearts? 
----
Nomura: It is the theme of the series. To explain it simply, a person has a body, a soul, and a heart. As an image, the soul is the life source, without it a person would be dead. Since the heart doesn’t have a form, memories play an important part in forming a heart. Also, the heart isn’t limited to people, but to all things. I tried to explain this concept to Disney, and they merely said that it must be an Eastern way of thinking. It may be interesting how overseas players think of it..
*Resurrection and Immortality (Type 9): When the Heartless' heart is freed, and the Nobody is destroyed, the remains bring back the original being as a whole where this separation happened (Not combat applicable). If such a place is not available, they're sent to Traverse Town.
*Abstract Existence (Type 2): A heart is made from light and/or darkness, both of which make up existence. Every being has its own heart, within which their memories are bound to.
*Empowerment: The user can amplify their own power over light by calling upon the power of others', even from multiple universes away, negative emotions can amplify darkness, which can also amplify the user

 “The darkness in my heart is making me stronger?” Staring at his hand, Riku bit his lip. The Parasite Cage attacked again. But it didn’t even scratch him. He leaped up and brought Soul Eater down on its head.
 The Parasite Cage let out a terrible shriek and dissolved into sparks of light. Darkness swirled around Riku, the same as before he found himself wearing the ink-black cloak, and then his outfit returned to normal.
 “The power of…darkness…”
 That strength, that speed—everything was much more than he knew he usually had in him. A shiver ran up his spine. Am I going to be swallowed up by the darkness…?
 He felt like the stench of darkness that clung to him had gotten stronger, too.
.
*Resistance to Data Manipulation: Ansem The Wise stated that the heart cannot be contained by data, and that the process itself would be incalculable.
*Resistance to Fusionism: A heart can't just merge with another if it isn't willing to do so. Conflicts of this manner are innately done in the Station of Awakening, which is a place based on a "dream" of one of the hearts involved, in which the one owning the heart and the other one may appear and fight accordingly in it.
*Resistance to Telepathy: The ability becomes ineffective to someone with excessive darkness in their heart.
*Resistance to the effects of darkness: A strong heart can resist the effects of darkness

Upon exiting the hall, Terra sat down on the stone steps of the yard and gazed into the palm of his hand. Failing the Mark of Mastery exam was bad enough, but the momentary burst of darkness within him troubled him more. Even frightened him.
He had learned something of the power of darkness. He also knew the fate of a heart consumed by it. And that power—was in him.
He had been taught strength was necessary to conquer darkness of the heart. Strength of heart—strength of body. Honing his physical capabilities would bring strength of heart in due course. If he then trained his heart in the same manner, the power of his Keyblade grew as well. He had learned all this.
.
*Resistance to Existence Erasure: Those with no darkness in their hearts retain the body and soul's existence after losing it.
*Weakness to Memory Manipulation: Memories are a vital component of a heart

"Memories are governed by the heart, but the heart is made of memories. A heart with no memories is already an empty shell."
, significant disruption of them can destroy a heart.
Note: Riku Replica's body not vanishing from existence out of this comes out of his body being a Replica, which are intended to be "existent" yet empty so they can be filled with a heart from elsewhere.
|-|Manipulation=
The following powers are inherently granted by the capability of manipulating a heart, rather than simply having one within the respective being:
*Transmutation, Existence Erasure: Those that have their heart removed and have a strong heart and will may become a Nobody, otherwise the remaining body and soul are fully erased from existence, unless it has no darkness whatsoever in it, in which case the body and soul remain in a comatose state until its heart comes back.
*Conceptual Manipulation (Type 1): Hearts make up all existence, with their most important components, light and darkness, being older than the universe. Naminé changing Riku Replica's memories caused a card to change form to the good luck charm he "remembered", which similarly affected the lucky charm Sora got from Kairi when his memories were changed as well.
*Information Manipulation (Type 2): Hearts are still a fundamental existencial aspect even in realms made of data, Datascapes, nonexistent beings (Nobodies) still behave as nonexistent even in such places.

A heart is made of light and/or darkness, the capability to manipulate either of the two aspects grants the following, yet it's to be noted that these powers are only for those that can actually manipulate either aspect, as having a heart or the capability to manipulate one doesn't inherently grants manipulation of light or darkness themselves:

|-|Darkness=
|-|Light=
These are inherent traits of light on its own:
*Light Manipulation: Self explanatory, light also hits beings of darkness effectively.
*Existence Erasure: Light can erase others.
*Conceptual Manipulation (Type 1): The light in hearts came from the darkness that was around since the universe's inception, and as a component of it that defines existence, it falls as such.
*Information Manipulation (Type 2): Hearts still define the existencial aspect of someone in the Datascape, a reality made of data, as Nobodies retain their Nonexistent Physiology out of lacking a heart in them.
*Resistance to the effects of darkness: (Light can mitigate such effectsKingdom Hearts Dream Drop Distance Novel, Chapter 8
----“Your heart will sleep forever in the folds of darkness. And your body will be another vessel for me. So light gives way to darkness. Good night, Sora.” The darkness crept in at the corners of his vision, until it finally swallowed him completely. I… Sora was descending into the depths of a profound darkness. And yet, a light quietly drew near, gentle and kind. It was a piece of someone’s heart, of the heart sleeping within Sora. Ventus. The light shone out into the darkness, illuminating Sora and bursting free from the gloom dragging him down into its depths.).
