Corruptions

The Corruptions (破損, Hason) are beings of darkness and the main enemies of Kingdom Hearts Epitome of Darkness. Most Corruptions are revived beings who have lost their souls and have died as a result.

Kingdom Hearts Epitome of Darkness
Corruptions make their first appearance in the Land of Radiance when they attack Avira while he is in a forest. The Corruptions use the of Darkness Corridors of Darkness much like the Heartless when they appear.

Origin
Corruptions are formed in a way similar to that of Heartless except that instead of the heart being consumed and separated from the body and soul, the soul is consumed and separated form the body and heart. In order to become a Corruption one must first die as in the Kingdom Hearts universe, a soul is the force that gives a being life. If a deceased being has high levels of darkness within their heart upon death, the heart and body of the being may both be revived by said darkness if the heart itself is strong. This means that Corruptions are basically living corpses or the undead.

Nature
Unlike Nobodies and Heartless the Corruptions do have hearts and are capable of showing emotion. Most of the time said emotions are negative as the hearts of the Corruptions are composed primarily of darkness. It is possible for a Corruption to feel positive emotions but is very rare. The fact that the Corruptions can actually feel emotions causes them to be deemed more dangerous than those of the Heartless and Nobodies.

Like Nobodies the Corruptions are vanished from the of Light Realm of Light upon their formation. Corruptions are usually formed within worlds located in the Between Realm Between. Due to the fact that their strong hearts contain large amounts of darkness, they can gain access to the Realm of Darkness after their birth.

When Corruptions are initally born their bodies usually take on new forms. If a heart is exceptionally strong it may however reject the new form; in this case the original body will be used as the vessel for the new Corruption and any decay of the body will be thus be repaired. Corruptions whose hearts were strong enough to maintain their original bodies make up the organization known as The Lost Ones whose members are known as the strongest of all Corruptions.
