Films: Vipers (2008)
Location: Civilized Area
Height/Weight: That of average vipers.
Summary: The government once again sees it fit to want to weaponize snakes. And when they decide to go for the venomous variety, we know everything's gonna go to Hell. Well, they really did it this time, because the horde of biters they made recently might just be the worst we've seen.
History: Bred in a lab, this group of horned vipers was made so that their venom could be analyzed and help pave the way for medical marvels. Then the vipers escaped due to a sabotage, and found new ground in Eden Island of the pacific northwest. Now they’re multiplying and tearing apart anything they can sink their teeth into, including humans. Either the islanders find a way to survive, or face both the snakes and a planned air strike to wipe the slate clean.
Notable Kills: How many venomous snakes do you know that tear apart much larger prey after biting it? Certainly none that target humans.
Final Fate: Many people and many more vipers die amid the chaos, but in the end, the entire viper nest is blown up, and the greedy fool who started this whole mess is ousted as a crook to the public. Then a surviving viper shows up in his limo and bites him to death.
Powers/Abilities: Aside from explosive breeding, these vipers have an amplified venom that doesn't even kill instantly, but gives them plenty of time to borrow into your flesh with sharpened fangs.
Weakness: Anything conventional.
Scariness Factor: 3.5-CGI bad, but new snake species even worse! As if vipers weren't dangerous enough already, we now have a breed that on top of being venomous is explicitly out to eat you. In numbers, no less. The deadliest snakes on Earth, yet they are still partially undone by a bad budget.
Trivia: -Vipers are the most venomous among snakes, characterized for their long, hollow fangs, the longest of which belonging to the Gaboon viper.
-Horned vipers are typically found in the deserts of Africa and the Middle East. They like to travel via sidewinding over the hot sand, and have a venom on par with the much-feared saw-scaled viper.
