Films: Boa (2001)

Alias: None

Type: Ancient

Location: Civilized Area/Tundra

Height/Weight: That of a truck

Affiliation: Neutral

Summary: If your idea of a prison is somewhere in the most inhospitable area on the planet, you'd better be prepared to make it the home of the worst people alive. Oh, and be aware of the prisoners who are already there...

History: Welcome to New Alcatraz, a maximum-security prison located all the way in northeast Antarctica. If that sounds like the worst thing ever, then you'd be right. But not just because it's a freezing Hell meant for the worst criminals around. Recently, some drilling has unleashed an ancient giant boa from its icy tomb. Now, both worker and prisoner alike are threatened with getting eaten, and there are few places to hide.

Notable Kills: Nothing special.

Final Fate: After killing most of the folks in the prison, the boa attempts to hitch a ride on the aircraft meant for the survivors to escape with. They end up tying a parachute to it, and send it flying back to Earth, killing it.

Powers/Abilities: An incredibly resilent hide and a sharp tail.

Weakness: Heavy artillery.

Scariness Factor: 3.5-Ideally, a monster snake with a massive stinger on its tail should be frightening, but in execution, it is let down by bad CGI. Honestly, the premise was scary enough with the whole "stuck in an arctic prison" premise.

Trivia: -The largest snake to ever exist was the Titanoboa, a constrictor that lived in the Paleocene epoch, grew up to 42 feet long, and lived in South America's first ever tropical rainforest.

-But before Titanoboa was discovered, the largest was its Eocene successor, Gigantophis, which only grew up to 35 feet long.
