Eight days ago, a purple light-like entity was seen flying from the abandoned and burned down Pokémon Mansion. The place had been evacuated and declared off-limits to everyone without an authorization by the police, after some incidents regarding scientists who stayed in the Mansion after it burned down, and acting hostile to those who entered the Mansion.
This incident was reported by a group of trainers who were staying at the Pokémon Center, resting before parting to Seafoam Islands. The first hypothesis made by the Cinnabar Island Police Station was that some scientists, possibly the ones who were in the Mansion before its burning, went back, ignoring its off-limits status, to experiment on more things. This was sustained on the testimony of the local Pokémon Center nurse, who said she saw "some weird-looking men" going inside the Mansion some nights before the incident.
A group of policemen went to examine the place the day after the reports, planning the arrest of the scientists who they thought were inside, for getting into a prohibited zone and doing scientifical experiments without the permission of the Pokémon Lab nor Kanto's Scientifical Guild. However, they found no living man in the Mansion: instead, they found seven human corpses, badly burnt, who weren't there the last time the police made a rutinary inspection.
They searched the place for any living man, or any hints, but they couldn't find any big evidence of what had happened. They took a few papers, folders and documents they found and went back to the Police Station. Investigators determined that the seven people were, in fact, scientists, and that they had died on April 11th around the time the purple light was spotten, according to the witnesses.
They also found some handwritten papers that one of the scientists had written over the course of their stay, before his death, as a "scientific" journal. The content of the papers is transcribed below:
//Diary: April 4th
Seven of the original Pokémon Mansion scientists, including myself, have reunited in our old workplace. One of us recovered the DNA piece we were studying last time, that one of Mew. Some of the machines we were using still work, despite the accident that happened last time. We are going to try to bring Mew to life, without the errors we did last time.//
//Diary: April 5th
We are succeeding in our experiments, We are almost finished with bringing Mew to life. It was almost the same process we did when Mewtwo, but we changed some steps and modified its DNA to make it not hostile to us.//
//Diary: April 6th
It's alive. However, this one looks exactly the same as Mewtwo. We modified it, its DNA is not the same! Something went wrong! This was not supposed to happen! The newly created Pokémon has not acted hostile to us and is rather calm, like if he knew something... It is in constant observation.//
//Diary: April 9th
It changed! It's not Mewtwo anymore! The modifications we introduced to its DNA needed some time to appear on its fenotype, but the Mewtwo transformed into a new creature. We did some studies on it, and it is not an evolved form. It's still the same Mewtwo, but with different characteristics. We called the new form "Awakened Mewtwo", because it seems to excel Mewtwo in all physical aspects. It has a really high physical power. We are still examinating it.//
//Diary: April 10th
The new Awakened Mewtwo is far too powerful! We are trying to control it, but it's becoming impossible. He has damaged some of our machines, and does not follow our orders. It's making a mess. My partners are in the room towards mine trying to make it obey, I'll join them after I finish writing this. I fear something like last time's accident will happen, or something even worse, considering this new creature's physical power. Only time will tell...//
The journal ends there.
Their final report was "Seven dead scientists. Cause of death: unknown. Possibly an accident while doing clandestine scientific experiments regarding clonation and a purple entity.".
Up to this day, no effort has been made to find out the truth behind their deaths, or the real nature of the purple light they saw.
Was it really an experiment? Was it the result of an experiment?
Was it an experiment gone wrong?
Only time will tell.
