The Shadow Figure

Could not think of a good name for him, so if you have one than maybe you could help me out and name him.

His story:
He enjoys lurking in the shadows, humming a familiar tune of death. He controls the shadows, using it to trap his victims. The creature could be anywhere in the forest, the woods, even in your house, hiding in the shadows across your bedroom waiting until you spot him. At night, he goes outside as that is the best time for the shadows to be surrounded everywhere. He hides in the shadows waiting for his victim to be near him. He continues humming until his victim spots him, making him stop and stares at him. The victim only seeing two white light, as if it was moving closer to him until he comes out. The victim wanting to run, but its legs would not leave making it a nice meal for the shadowy creature. The shadow figure has seems to look to have three hands covering his face. A long right arm, a normal size left arm, and an arm at the back. The way he walks is all crooked like. His left leg longer than his right leg, his foot backward on his left leg. He slowly removes his hands, revealing his mouth glaring as bright as his eyes. Another hand slowly comes out with tentacles. It strikes directly at the victim's chest, but it just goes through and does not even hurt at all. Once he brings it back in his mouth, the victim faints waking up the next day. Once the victim comes out, it will be invisible to the world and everybody will not remember about the victim as if it was not ever born. Things the victim interact with will just go through, but sends some pain throughout it's body. Not to mention, the shadow creature will stare at the victim, his eyes glaring at him and his hands covering his face again, humming the tune of death.
