Films: Pitch Black (2000)
Alias: Big Boys
Height/Weight: That of average rhinos.
Summary: Many planets in our solar system appear to be barren and lifeless. And perhaps in other galaxies, it's the same way. But maybe we're just not looking at the right time. And even then, do we want to?
History: The planet M6-117. A barren, inhospitable blight on its galaxy, seemingly bereft of life and/or purpose. But all of that changes every 22 years. Once those years are up, the planets and the stars align, creating a months-long eclipse that blots out all of the light, leaving nothing but dark. Perfect for this planet's only major form of life. A swarm of awful carnivorous monsters known as the bioraptors, which can only live in darkness, and spend their privileged days eating everything, including each other. But today, a special buffet table in the form of a crashed ship full of people has come. It seems like good news for the beasts, except one of the crew happens to be the most feared convict in the galaxy. The man known as Richard B. Riddick.
Notable Kills: In the dark, you're naturally going to want just a little light. Imagine getting it...and seeing over fifty monstrous heads staring at you waiting for it to dim...
Final Fate: The bioraptors kill just about everyone except for a couple survivors and Riddick himself. Before taking off on a ship, the man makes sure to attract as many of the creatures as possible before incinerating them with the ship's engines. Now the bioraptors wait for some more prey to come here, while Riddick sets off on other adventures.
Powers/Abilities: Bioraptors can see perfectly in the dark.
Weakness: They cannot tolerate any form of light, and can be killed via conventional means.
Scariness Factor: 4-Sure, the CGI isn't always up to snuff, but let's take the time to admire just how perfect these nocturnal killing machines are. They eviscerate you in numbers, the babies can actually kill in the light like a swarm of locusts, and if there's no food around, they'll just go and murder one another like savages. It's saying something when the only thing that can stand a chance against even one is the ambiguously human Riddick.
Trivia: -This film was the breakout role for Vin Diesel, who played Riddick. From there, he became a staple in playing rather imposing characters, including Dom from the "Fast and Furious" franchise and Groot from the "Guardians of the Galaxy" films. However, we should not forget that he was the voice of the titular robot from "The Iron Giant" before all of that. Forgetting would be sacrilege.
-This film, due to the character's popularity, became the first in a trilogy chronicling Riddick's adventures. How you feel about those films is honestly a matter of personal interpretation.
