Film: Devil Monster (1946)
Height/Weight: That of an average Manta Ray.
Summary: Man will never stop being afraid of the unknown. And because of this, anything that looks slightly unfamiliar will inevitably get demonized in some way. Example? They turned a harmless manta ray into an alleged movie monster.
History: At some point, a young man named Jose got stuck at sea and became stranded on an island populated by beautiful women and food/drink galore. Unfortunately, more than a few people came looking for him to take him away back to civilization. Understandably ticked, Jose guided them straight into the domain of the Devil Monster, a notorious manta ray known for menacing anyone who crossed its path.
Notable Kills: None.
Final Fate: After getting stabbed and skewered by countless harpoons and daggers, the Devil Monster backs down and leaves to watch the rest of its species land on the endangered species list.
Powers/Abilities: A ridiculously resilient hide.
Weakness: Heavy artillery.
Scariness Factor: 1-The "Devil Fish" is just a manifestation of man's misconception of the manta ray, as the real thing is docile and poses a threat to almost nothing. The one in the film also doesn't really do a whole lot.
Trivia: -The manta ray is the largest ray in existence, and was indeed nicknamed the devil fish for its sinister appearance. Nowadays though, there's barely anyone who doesn't admire them.
-This film is actually a re-edit of a ten-year old movie known as "The Sea Fiend".
