The raptor that was formerly Jeff paused in its destructive rampage, fascinated by the bright sparks that was coming off the broken computer. It put its muzzle close to the computer, sniffing it to see if it was edible or not. Then a spark hit the raptor's nose, causing it to jump backwards with a screech. The bright thing hurt its nose. It should be destroyed.
Then an odd feeling went through the raptor's body. Its hips felt uncomfortable until they suddenly lurched upwards. The raptor hissed with confusion as its spine was being forced upwards. The legs stretched longer as they adjusted to this new stance. Its torso widened as muscles redistributed. The raptor's belly shrank away as lightly defined abs appeared. The raptor's forelimbs were forced farther apart as its shoulders broadened. They grew longer and more muscular as his lost thumbs and pinkies reappeared and his paws became more dexterous hands. The raptor grimaced as its snout was pushed back in, its eyes growing closer together as hair grew again on top of its head.
The raptor's brain swelled as memories and knowledge was recovered. With a blink of its eyes, the raptor intelligence faded and Jeff was restored. Jeff looked around at his trashed room. Looking at his shattered mirror, he saw not a pure Velociraptor, but a human/raptor hybrid. He had to admit he looked handsome as an anthro raptor, even if his hair looked out of place. He looked around at his trashed room, clawmarks everywhere. He could vaguely recall what he had did during the brief time he was a pure raptor. He could see where he had messed up. If he wanted to live a pure, primal life, he should have had the Chronivac send him to an uncharted jungle where he could live feral and free.
"The Chronivac!" said Jeff, his voice sounding raspier than before. He turned to look at his computer and saw it was destroyed beyond use. But the power obviously wasn't completely gone. The computer was still sparking, the Chronivac program still displayed on what was left of its screen. Then the sparking got more intense as a bright light started to build up around the computer. "Uh oh," said Jeff as he saw things were about to get worse.
