28. The Tremonds/Chalfonts
The first of several supernatural entities connected to the malevolent Black Lodge that you'll see on this list, the Tremonds (as they're called when Donna Hayward encounters them on the TV show) or the Chalfonts (as Laura comes to know them in Fire Walk With Me) look like an elderly woman and her well-dressed grandson. They lead both Donna and Laura deeper down the rabbit hole of…whatever it is that's going on in Twin Peaks, then disappear. They are as creepy as they come, and their scares-to-screentime ratio is alarmingly high.
