In the military base known as Area 51, ten scientists were clustered around the corpse of the first Tyrantis. The head, spine, feet, arms, back, and tail had all been removed to create the cyborg MechaTyrantis, but there were still many pieces left of the monster. There was one puzzling part about these pieces: the main body had begun to heal its wounds! The scientists were sure that the body would decompose once it lost contact with its brain. Instead it began to regenerate slowly, and now every exposed wound had closed up. What remained was a huge pile of living flesh that was growing rapidly each day.

As the baffled scientists studied the growth, the body stirred. Seven spines suddenly shot out of the body's back in a matter of seconds. The scientists were in awe, unaware of the chaos that was about to ensue. Two tiny hind legs followed then a tail. One huge front leg popped out on the right side, then a left one. The "corpse" stood up, supporting its weight on its front legs and tail while the smaller hind legs flailed about. A bump appeared between the creature's shoulders, and soon began to grow larger and longer. It opened, revealing three sets of teeth. It finally emerged, opening its large yellow eyes. The monster roared as horns began to jut out of his face: six on his nose, three above each eye, and two long, bull-like horns behind each ear. The monster roared again then looked at the puny humans. It smiled and quickly blasted them with a dark purple ray. They screamed in agony as the creature left, tearing a hole in the ceiling.

The ten scientists continued to wail as their bodies began to mutate and grow. Their hands lost two fingers, and the remaining three grew longer. Their legs were growing spikes and stronger bones. They felt their teeth growing larger and more serrated. Soon their hair fell out and was replaced by a crown of horns. By the time the mutation was over, each scientist had reached a height of 25 meters. They also had retractable claws and rough, purple skin, along with a craving for meat. Human meat.

The monster that mutated from Tyrantis' butchered corpse could smell his minions. He would call on them when they were needed. For now he would rest. He had a long journey of destruction ahead of him. The horror of OVDG had begun.
