He who makes you scream

ALMA WADE
She was in: The 'F.E.A.R' series
Judging by the picture, you'd guess by now that Alma Wade is a freaky-looking ghost. 'F.E.A.R' fans would know how creepy it is to bump into Alma, especially when you turn a corner and she's there right in front of you, all bloody and all. Then, you'll need to pause the game to change your underwear.
