Shadow-walkers

Shadow-walkers are evil and dangerous beings who thrived around the time of Gus the Awesome and Awesome-ites. Awesome-ites were often the enemy of Shadow-walkers and would always have fights to the death. Shadow-walkers are said to have originated from the planet Kepler-32b. As years passed, the Shadow-walkers were spread all over the universe reaching a total population of what is estimated to be: 57.9 billion per galaxy. However, when a deadly cloud of poisonous gas collided with their home planet, no more Shadow-walkers could be born from what they called "the hive." The Shadow-walkers slowly died out and only 5 have been known to survive (including Stan who was later killed). The Shadow-walkers' ultimate goal was to evolve into an Un-Awesome-ite and then take over the universe. Although The Great Un-Awesome did achieve this, he was not part of the same species. One of the remaining Shadow-walkers is in captivity where it is observed my scientists. Two other have been trapped on an undisclosed  planet where they will stay due to a shield around the planet. 1 was seen flying through space in 2005.
