It's been a while, but I've been workin on stuffs. I just did an entry for a Silent Hill contest on deviantART, and this is it.
What it represents:
The creature represents depression through the means of it's birth, actually. What the creature itself is, is the fleshy body in-between the halved-human. How it reaches the state of depression is through tearing the human itself in half (much like depression does in a non-literal sense) and feeds on both halves as one with each mouth. Another eerie representation of depression comes from the head it holds. The head seems to live and react to situations, but mainly the look on it's face is that of complete sadness. You can also hear the creature coming because an audible "sobbing" sound can be heard coming from said head. Also, it seemingly never stops crying blood.
This creature can usually be found within hospital corridors. The creation of it is unknown, but since it's dwelling never changes, it's greatly speculated that it was some sort of medical misshap. Some believe it was a cancer-cure gone terribly wrong. The creature has 4 arms with hands and two with blades. It uses the blades to sever a human being in half, and uses two hands to grab the bottom half, and the other two for the top half. It has two mouths, that the arms feed the limp bodies into, and lives off the blood of human beings.
The head itself, no one really knows where it comes from, but it's always of the same morbid face, so, many believe that it's a "portrait" of the original creator.
Without a human feeding source, this creature is known to be extremely deadly, as it is on the prowl for human blood. It will attack and attempt to sever any human life-form it sees. Although, when feeding off a human, it tries to stay alone and out of sight, for fear of losing it's life-source. It will attack if threatened or approached in any way.
Some have seen this creature and lived to tell about it, and have noted that if approached slowly and carefully, it will not react. When within a reasonable distance, the sobbing can be made out to phrases of deep sadness. "Please... Leave me... Leave me now... I don't deserve... I have nothing... It's best for you to go...." are some examples of what they might say.
