Meteorites are terrifying on their own — but let's not forget they're often carrying dangerous cargo.
Superman
As seen in DC comics. I know what you're thinking: Superman isn't scary. But think about all the destruction that follows him around. If you've got a superhero in your city, you've got supervillains, too.

Cybersuit
As seen in Star Kid. Believe me, you don't want that kind of responsibility. It's all fun and games until you have to battle a Brood Warrior from the insectoid race waging war against the suit's creators.
Zirkonians
As seen in Aliens in the Attic. These little guys are probably more annoying than dangerous, but you can never be too careful. One is voiced by the very intimidating J.K. Simmons!

50-foot woman
As seen in Attack of the 50 Foot Woman. The meteor doesn't actually bring the giantess, but it does harbor the alien that turns this normal human into a creature that can crush, kill, destroy.
