SCP-200: Chrysalis

SCP-200: Chrysalis SCP-200 was a thirteen-year-old boy before he enclosed himself in a chrysalis attached to his bed. It's about 1.72 meters long, mottled brown, and made from layers of coarse silk. Nobody knows how a human child produced enough silk to build it. The material binding the layers together is redacted, but its DNA matches his too. His medical history was ordinary until he turned twelve. Then his appetite increased dramatically, and he gained weight rapidly over the following year. His pediatrician couldn't explain the change in his metabolism. The file's last measurements put him at 152 centimeters tall and almost 169 kilograms. When his mother tried restricting his diet, he ran into the woods. Authorities found him seventy-two hours later, having doubled his weight by eating something the document doesn't identify. After he was brought home, he formed the chrysalis. The Foundation recovered him about twenty-eight hours after it appeared. The scans are where the situation gets stranger. Ultrasound cannot find any solid structures inside. Fluid samples contain human DNA matching the boy, but the entry redacts the researchers' account of what has happened to him. We can see that something has radically changed. We aren't given enough information to say exactly what remains inside or how the transformation works. Most of the time the chrysalis is still. Sudden contact or loud noise can make it twitch. In its current state, the file says it poses no threat. Staff keep it in a secure room with the bed frame and mattress still attached, observe through a window, and disturb it as little as possible. An automated mister keeps it from drying out, with care taken not to make it too wet or damage the outer shell during sampling. Later tests find mutations in its DNA. A researcher proposes an explanation for what the boy might become, but that proposed outcome is also redacted and remains controversial within the Foundation. That uncertainty leads to a Euclid classification and continuous observation in case something emerges. There is no emergence scene or confirmed adult form in the entry. His mother, doctor, and the local authorities have had their memories altered, and a cover story explains his disappearance. The Foundation is left watching a child's bed and trying to understand a process already underway. Even whether the original boy can ever come back is left unanswered.
