First appearance: Evil Dead 2: Dead by Dawn (1987)

If you some how don't know what this movie is about and consider yourself a horror fan, welcome to planet earth! Anyway here's a quick sarcastic synopsis of the movie... I've already written about it at least twice before... Evil Ash, Ash, Bad Ash... 
Some cheap jerk takes his date to a cabin in the woods that belongs to someone else. the guy then unleashes a bunch of evil that proceeds to ruin his date, possess his hand and kill a couple innocent hillbillies. In the end it turns out all the evil is his fault anyway since he didn't do a good job getting rid of it when he was sent back in time.
