Gluttony

It's the year 3026, and humanity has become near extinct from overpopulation and global warming. People dug for reasources more and more, until they eventually found something in a cave, something that wasn't meant to be freed. And from years of being trapped in that cave, the monster had grown hungry. This monster is now known as "The Worm" though it is also called gluttony. It gets it's many names from it's large appetite and horrifying worm-like appearance (It's actually much more like a centipede). This freak of nature eats anything that moves. It somehow learn english and roars as it searches for food. You aren't very lucky and end up finding Gluttony, and now you have to make sure it doesn't find you. If that wasn't bad enough, you just got done raiding a grocery store, and Gluttony has a great sense of smell. You can be anyone, good luck. (Ignore the voice)
