Based off of the game Eyes The Horror Game and the Indonesian ghost "Palasik", (also known as the "Krasue" according to Southeast Asian folklore) it is known to eat infants in the mother's womb.
It's appearance is that of a disembodied head with floating organs. It emits a red glow from it's body and "sings" on occasion. In game it bears a similar vision to Predator and Terminator but with blue vision.
Krasue's ability allows her to see players through walls, similar to a wall hack.
