Story:

It was just a normal, average boring day. Nothing was going on. So, the man decided to go for a walk. when he got to the door someone knocked on it. He opened it and his vision suddenly went black. He woke up in a chamber with 12 other people. All of them-including him- were buckled down into a chair. A man in a white suit walked up to the man. He put some kind of a juice in the man's mouth. He started thrashing, he started yowling, he started.....growing. He grew so big the buckles broke from he hands and feet. He started yowling more and more until he stopped and put his tiny yellow, glowing eyes full of hatred looked down on the white men. He, no, it picked up the one that put the juice in his mouth and threw him against the wall. Then the next one, then the next one, until there were no more white men. Those white men started to grow too, but they were still a lot smaller than the bigger one. They bore down on the others that were in the chairs, then they grew. it spread across the world until only one person was left alive.
