Is there life beyond our planet? We tend to think that it’d be pretty self-absorbed to believe that in all these universes, our pretty standard little Sun and planet allowed for the only setting for life to develop. But, hey, we’re not astrobiologists or philosophers. But we do know that human imagination has allowed us to dream up all sorts of extraterrestrial life, from the very cute to the truly horrific. With that spectrum in mind, maybe it is better to not know the answer for sure... 

We asked Cracked readers on Facebook, “What pop culture alien would be the most dangerous?” Xenomorphs from the Alien franchise (pretty on the nose there) were the clear winner, but some others have some strong arguments for other fictional creatures. We were even pretty swayed by the Mork response. Read on to read more about the scariest creatures to come out of the sci-fi world.
