Film: The Beast with 1,000,000 Eyes (1954)
Summary: Imagine being able to see the world through anyone and anything else and manipulate those who allow it. The power sounds immeasurable, doesn't it? That's what this would-be planetary conqueror thought.
History: Hailing from a dying planet, this alien's species is one that feeds on fear and all other negative emotion. However, due to a literal lack of a soul, this species perished for the most part, unable to show anything other than contempt for all life. However, this one escaped extinction, and set out to Earth to enslave all. He started with simple animals, but now he's setting his sights on lowly humans...
Notable Kills: None.
Final Fate: After a family discovers the alien's weakness, they use it to send the alien's mind into overdrive, killing it.
Powers/Abilities: This alien can manipulate the minds of a large group of individuals at the same time with only his own mind.
Weakness: Due to lacking a soul, this guy has no concept of love or joy. Rejecting his control with happiness is not something his great mind can comprehend. Power of love, everybody.
Scariness Factor: 1.5-He got. Rejected. By the power. Of love. And he was doing so well beforehand with the mind control. His visage is also a little hard to comprehend.
Trivia: -The filmmakers allegedly bent over backwards just to have a monster in this film, despite it having a near-complete cut already.
The monster puppet was nicknamed "Little Hercules" by his creator because...we have no idea.
