It was a very powerful storm above the community of Cerulean city on the night of June 16th, 1997. The thunder was loudly booming, the lightning was crackling, and the rain was pouring down hard. But despite the storm, most of the city was sleeping in peace. That is, except for one man, who was crawling out of a manhole in a state of fear and shock. He was a middle aged man wearing a white lab coat. He was being chased by a powerful creature that was following him through the sewers. He ran with all his might. But below the ground, whatever was chasing him was hot on his tail. The man ran steadfast for the Cerulean Gym, hoping to evade the unseen creature by getting indoors. Inside the gym, the Three Sensational Sisters were doing another one of their synchronized swimming shows, performing before an enthralled audience. Meanwhile outside, the man still ran for the doors of the gym. Another younger man, sitting on a bench next to the doors, saw the middle aged man running, at first not knowing what to make of the situation. Then at that moment, the unseen creature attempted to burst through a set of grates that the man was walking, the powerful uplift sent the man flying forward and landing on his stomach. The young man then got up off of the bench and decided to try and help the middle aged man who desperately calling out for help. But just as the young man was about to help the older man up off the ground, the unseen creature burst open the grates, scaring away the young man, grabbed the older man by his ankles, and started dragging him back down into the sewers. By the time it was all over, the middle aged man had disappeared below the grating, and no one inside the gym had noticed what had happened because they were applauding the performance of the Three Sensational Sisters. But the events of this night were just a foreshadowing of what was to come in the biological crisis of Cerulean City.
