Films: Spasms (1983)
Location: Jungle/Haunted home
Height/Weight: That of a boa constrictor.
Summary: Out of all the snakes we've encountered before and even since, there is none that we would give a hard pass to being bitten by than this horrible thing. How it amassed such a following in its habitat just raises questions that don't need answering.
History: A serpent with psychic powers AND the worst venom ever lived in the jungles of a lost island, and was even worshipped by the natives. It also happened to have a bizarre mental connection to a man who had lost his brother to it years ago. Now, the beast has been captured, and it would have been sent to scientists had some Satanists not broken it out of its confines. Now, it's loose on a campus and killing everyone in horrible ways.
Notable Kills: You DON'T want to see what happens when a guy gets bitten. Just know that they'll have an, ahem, inflated view on themselves.
Final Fate: The serpent and its rival soon have a final confrontation, which soon ends with the beast getting an eye gouged out before the man succumbs to his injuries. Then another guy gives it a mouthful of AK-47, killing it.
Powers/Abilities: Telepathy, telekinesis, and if there is a big enough venom dose, it can cause people to inflate and explode.
Weakness: Anything conventional.
Scariness Factor: 4-Litterally the only thing holding this horrible reptile back is that its prop isn't the most graceful thing to watch in motion. Aside from that, you got a snake that can fling you across the room with its mind and make a cobra's bite look like a harmless nibble.
Trivia: -That weird array of flashbacks in the 3rd act? It was due to the production money literally running out, so padding was necessary.
-The worst snake venom belongs to the saw-scaled viper, if only because there is little anti-venom to go around, it alone can cause mass hemorrhaging for days, and the body count these things have is one of the greatest of any serpent.
