Bubak

"Sitting in the green shed, behind our bicycles and resting in between six large jars of jam, was a scarecrow. I can't exactly you what it was, but the thing always gave me an uneasy feeling. The aged straw it was made out of or the tattered clothes of children it wore really didn't bother me. It was its eyes. They were strained, human-like. And the color was completely sickening: a rotting, almost fleshy pink."

- Ethan describing Bubak upon his first encounter "It will be better this way..."

- Bubak Bubak, the Sack Man, or the Man of straw is a sadistic demon who takes the form of a scarecrow and the true main antagonist of the Creepypasta of the same name. Along with eventually being revealed as the entity responsible for the strange events occurring at Ethan's home, including the disappearance of his entire family, he is the manipulative force influencing Ethan's grandmother into preserving the bodies of his deceased family members in scarecrows. He is eventually confronted and overcome.

He was created by SlothIsBack.

Origins
The Bubak (or the Sack Man, as he is referred to by locals) first arrived into the human world, according to pagan Slavic priests, amidst the bubonic plague. He was sent by Chernobog as a messenger to the people, giving them the word of Chernobog's will. The spirit instead began developing sadistic tendencies and used the powers granted to him by Chernobog for his own use. Chernobog punished Bubak severely, stripping him of his god-like abilities and cursing him to roam the world of man for eternity.

Bubak's sociopathic ideals began to slowly consume him as he began feasting off misguided souls, mostly those of children as they were easier targets and generally more naive than adults.
