Film: The Astounding She-Monster (1957)
Height/Weight: That of an average human.
Affiliation: Neutral, leaning on Good
Summary: When sending an emissary to go out and see other places, it is customary to find the most intelligent, savvy, and worthy person for the job. So sure, send the gal that destroys everything she touches and gets frightened of everything to do it! What could go wrong?!
History: Somewhere in our galaxy, there is the Council of Planets. These intergalactic aristocrats have been observing Earth for quite some time, and have decided that the human race is finally worthy to join them today. So they sent a resident from the Antares star to act as an emissary. Unfortunately, this alien lady had no conception of the English language, had a radioactive touch, and was quick to go on the defensive upon being slightly provoked. Brilliant choice, folks.
Notable Kills: Killing a bear with a touch counts.
Final Fate: Eventually, the She-Monster gets an acidic substance to the chest, causing her to scream and fall to the floor, where she disintegrates. It is only now that the humans realize her true intentions. Bummer.
Powers/Abilities: The She-Monster is radioactive to the touch, and immune to most weaponry.
Weakness: If one can find a way to break through her radioactive barrier, she's dust.
Scariness Factor: 3.5-She ultimately had the best of intentions, but there was literally no reason to send in an emissary this dangerous. Being a walking radiation stick isn't exactly the best way to say hello to different species, you know. The Council is probably shaking their collective heads in embarrassment at this point.
Trivia: -The Antares star is one of the brightest stars in the Scorpio constellation.
-In the UK, this film is known as "Mysterious Invader".
