20. Surgat

Surgat is one of the lesser-known demons of the Christian faith but his deceptive abilities make him one of the most frightening, especially if you’re a child who’s afraid of the dark. See, Surgat is also known as the demon who opens all the locks and tends to love dark places the most. In other words, even if you double-lock your door and hide under your pillows and covers, Surgat will find a way to come scare you, and what you’ll see won’t be pleasant.

19. Kokabiel

Kokabiel is described in the Hebrew Bible as the angel of the stars. According to both Hebrew and Christian traditions Kokabiel was a high-ranked angel who loved humans, serenity, and the sky; and was the one who taught the other angels everything about the stars. However, all this changed when he was cast out of heaven and was reclassified as a demon.

One of the few little things we know about Kokabiel is that he had about 365,000 other angels and spirits under his command but for some reason he became an ungodly demon and a terror to human souls.
