Has there ever been an enemy or boss in a videogame that ever made you not want to finish? Or was it scary but you pushed through it anyways? Post your little stories here. Also, post pictures of what these enemies look like, if possible.

Warning: Some images of enemies may be unsuitable for younger audiences. Moderation reserves the right to remove any image without consent of the poster.

For me, the scariest on was "It" from resident evil four. The first time I was attacked by that thing. I kind of jumped, said some very naughty words, and said, omg I think I'm going to die.
It's not cool to have the thing follow you throughout the whole level, constantly stalking you and putting you on edge making you wonder if your going to get completely owned by the thing.

I'll post a picture later if I can.
