Film: The Bad Seed (1957)
Location: Civilized area
Height/Weight: About that of an average 8-year old girl.
Summary: Aww, look at that little girl. How pristine she looks with that winning smile and pretty dress. Such a sight can only be called a beacon of innocence. You know, except when it very much ISN'T...
History: Little Rhoda Penmark is not a Penmark at all. She is the daughter of Bessie Denker, a serial killer with a mean streak. She was adopted by the doting Penmarks at a very young age after that woman's death. Inexplicably, Rhoda had inherited almost all her biological mother's insane qualities, particularly a sociopathic desire for all to bend to her will OR ELSE! At first, all the pampering her adoptive family gave her sated that desire. But then a kid won against her in a penmanship medal competition. That kid is drowned dead now.
Notable Kills: Drowned a kid and set a suspicious man's house on fire while he was sleeping in it. Cripes.
Final Fate: After her medal gets thrown into the lake, Rhoda goes to retrieve it at night. However, a massive storm is underway, and a single bolt of lightning hits the wharf she's on, blowing the evil half-pint to kingdom come.
Powers/Abilities: Nothing except her sociopathy.
Weakness: Anything conventional.
Scariness Factor: 4.5-Deception is key for any sociopath, and Rhoda had it nailed to a T. And that's what hits the hardest: literally anyone you know could be just like her. Just let that sink in.
Trivia: -Rhoda might be the first murderous child in cinema history. She certainly will not be the last.
-Although this film is billed as also a mystery, it should be obvious from the title as to whom the culprit is.
