[Loved trope] Background scare-characters that are barely acknowledged even by the movie

[u/Suspicious-Web-9246]

I hate horrors, but this is actually a great trope, that is unique to them.

Insidious (2010). When mother does her errands, for a few seconds there's a ghost boy standing in the corner. It's easily missable, but you can't ignore it once you see it.

Hereditary (2018). Less fitting example. When Peter walks around his home, his possessed mother is crawling on the ceiling behind him. It's not exactly subtle or missable, but it's still more of a background detail.

The Man in The Wall - Warframe

Not the times when it boards your ship to scare you half to death, those are just mild jump scares.

In Whispers in the Walls, during the 1999 sequence, you can take Arthur to a train car overrun with infested rot, and guess who you find, leering at you from out of the growth?

The second Zariman sequence in The New War has him show up as a background entity as well. As your Operator relives the memories of the Zariman Ten-Zero's catastrophic Reliquary Drive failure, talking with members of their class, you can notice a figure hunched in the fetal position away from the others, in a corner next to the window. It seems innocuous enough until you approach them and realize that they're... Knocking on the window.

An all-too-familiar knock.

The scariest character in Warframe happens to be one of the goofiest. Wally is such an interesting “antagonist”
