There once was a population of Care Bears that lived in a faraway place up in the clouds called Care-a-Lot, it really was a sickly place full of love, hugging and bears talking down to other bears that didn't follow the Care Bear Dictatorship.

One down trodden bear wanted to inject some fun into the Care Bears, putting some "fun powder" he bought off a bear in a very dark nightclub into their morning Rainbow Juice.  

The Care Bears all died because they overdosed on the powders (Silly Bear mixed up ounces for grams).  But they did not stay dead for long, they became the Scare Bears, Care-a-lot became Scare-a-lot, the rainbow roads turned blood red and they hunted down any bear with a pulse.
