Heartless



Heartless are the darkness in hearts of living beings given shape and form. They have a thirst for hearts, and are most attracted to pure hearts, such as Sora's. Their existence became known after one was created by Ansem, as revealed by his reports. Artificial Heartless were later created by Xehanort's Heartless. They first appear in Kingdom Hearts.

Origin
Though the origin of the Heartless is not explicitly described or shown, there was one point where there was not a single person with darkness in their heart, and only light existed, and as such all the worlds were connected. However, people began to grow selfish over the light, and thus darkness was born in their hearts. This darkness eventually consumed the light, but the children of light were able to craft new worlds, though they would remain separate. However, the greatest light would reside in the darkness, and until the day comes when that light breaks through the darkness, darkness would continue to thrive.

An unknown, but large, amount of time later Ansem the Wise, the ruler of the Radiant Garden, discovered the threat of the darkness. In order to combat it, he and his six apprentices, Xehanort, Braig, Dilan, Even, Aeleus, and Ienzo, tried to find a way to prevent the darkness from consuming the world, performing many experiments on the human heart. However, Ansem the Wise began to see the immorality of what he was doing, and ceased his experiments.

But Xehanort and the others continued with their experiments, discovering the Heartless and their nature. They constructed a large factory that could reproduce the creation of Heartless, thus making Artificial Heartless. Thus, the Heartless, once a minor threat, turned into a force that threatened all the worlds.

Heartless Types
Pure Heartless are the natural Heartless, born when people's heart are normally consumed by darkness. They are ink-black in color, with yellow beady eyes. They are more common in nature in places that are close to or saturated in darkness. Upon their destruction, they simply disappear in puffs of darkness.

Artificial Heartless, on the other hand, are created from machines that reproduce the process of a heart being consumed by darkness. They have more varied shapes, colors, and are branded with Xehanort's symbol to differentiate them from the pure ones. They mostly appear in the many worlds that reside in the realm of light, unlike natural born Heartless.

Nature
Heartless, artificial or not, possess several key characteristics that define them as Heartless. All Heartless are created when the darkness that resides in a person's heart consumes him or her, thus giving the darkness shape and form (this process occasionally form Nobodies, which are born from the body and soul left behind when the heart is lost). Being born from darkness, they are mindless and master-less, and their only goal is to find hearts, wishing to consume them and consequently create more Heartless. But what they desire above all are the hearts of worlds, and thus they enter worlds in search of the way into the hearts of the worlds. When they consume these colossal hearts, the remains of the world form new worlds, such as Traverse Town and the End of the World.

At the same time, Heartless seek out the users of the Keyblade, since the Keyblades are weapons of light, light being the greatest enemy of the Heartless. In order to stop the users of the Keyblades, the Heartless use the Keyblade itself as a homing beacon, but ultimately desire to take the heart that commands it. Because of this, Keyblade wielders are under constant attack.

Ranking
Heartless, being formed from darkness, have varying strengths, depending on the amount of darkness in a person's heart. And the greater the darkness that forms a Heartless, artificial or pure, the more powerful and more monstrous it gets. This is a direct contrast to Nobodies, which determine strength by the strength of the will, and the more powerful a Nobody is, the more human it appears.

Control
The Heartless, being mindless, usually have no master to direct their actions. However, there are some higher beings who can command them. But the key to controlling them is an affinity for darkness, and a strong will. Those with hearts, such as Maleficent, endanger themselves however, as the Heartless are attracted to their hearts. If they show weakness, the Heartless will not think twice of consuming their hearts.

On the other hand, higher ranking Heartless, like Xehanort's Heartless, can fully command other Heartless without endangering themselves. Also, Organization XIII is able to command them as well with their strong wills, but are not endangered of being consumed by them for their lack of a heart.

Travel
Heartless make use of the "corridors of darkness", inter-dimensional pathways that connect the many worlds. These pathways are located in the Realm of Darkness, and thus are very dangerous to use if one is not accustomed to the darkness.

Residence
The Heartless reside wherever darkness is abundant, especially the Realm of Darkness. However, they also reside in places such as the End of the World, a collection of the remnants of worlds that is located near the darkness. Another area that the Heartless live in is The World That Never Was, the world of the Nobodies that rests dangerously close to the darkness upon which the Heartless thrive.

Kingdom Hearts
Heartless, as they seek and consume hearts, also desire to return to the greatest heart, the heart of all worlds, Kingdom Hearts, that resides deep within the realm of darkness. And because of this, immense darkness, enough to completely consume the realm of light. The entryway into this place of great power is the Door to Darkness, the door that separates the realm of light and the realm of darkness. However, with the efforts of Sora and the King, the door is closed, which causes the worlds lost to the darkness to be restored, and preventing a massive army of Heartless from pouring into the realm of light.
