Blackheart

Blackheart is a highly powerful being that calls itself the very meaning of vengeance. He lives up to his cursed reputation by being an angel of death, the spirit that haunts battlegrounds for fresh kills, which somewhat sustain his existence by fueling his need for strife based on the need to get revenge. He is also referred to as Cain, the first murderer in written history.

Appearance
Blackheart has no true form, reflecting the appearance of his host, or the last known if the current one is dead. Currently he takes on the form of Hayashi Kagekyo; short hair, jacket and right down to the boots a perfect facsimile, but with an entirely black coloration, save for his facial features, which are red.

Personality
As stated previously, Blackheart is the spirit of revenge incarnate, and he acts the part. In his first known possession of his current, or rather prior, host, he started whispering crude words to encourage the fight against his Godfather. While he does act cruel to anyone and everything, he knows he needs a host, or if one is unavailable, that he needs a war to start, revealing a savant behind the bitterness.

Powers and Abilities
Powers Nigh-unlimited Spiritual Energy: Blackheart has a level of spiritual energy that most living beings could never fully grasp. He claims that eons of war have allowed him to ascend to where he stands now, along with being cursed by a God.

Immortality: Blackheart has lived from the age of Adam and Eve, something that only a being from before the beginning of time itself can lay claim to doing. The reason behind this is unclear as of yet, but it is believed that it’s from the day he was condemned by God to live forever, and any who attack Cain, vengeance will be meted out sevenfold.

Possession: Blackheart his capable of taking full control of any living thing that has a need to have vengeance on anything, feeding on it. When he does, the first clue is the anger the unfortunate possessed was feeling becomes almost palpable. After this, the next hint is the ‘host’ is conflicting in their actions and statements. During the possession, he is able to use any ability the host can and amplify the power levels.

Sen Kado Rei (千 角 霊 lit. Thousand Edge Soul): Blackheart, using his possessive abilities, can take the Zanpakto of any of his hosts and physically manifest it in Shikai state. While inside another host however, this power is ineffective. Thanks to this ability, Blackheart is quite litterally a walking fortress
