You were the child of two scientists working on recreating and containing Mewtwo. You didn't really know what your parents were doing in their company's lab and they never really talked about it.
Until one day you were invited to their compound. Your security had been juged as too poorly took in account and it was decided that you would stay in the compound with you parents from now on, cutting you from the outside world wether you like it or not.
You were not allowed in the main lab, of course, the scientists didnt want to take any risk of security breach of information spreading. Althought you were curious, and a simple "no" from your parents never stopped you from following your guts. So you had stolent a card from your parents at night and badged into the lab during the night.
You paced around, looked at paper and stuff until your eyes set on this huge tank tube filled with liquid in the middle of the room. And your eyes widenned as you saw the being inside... Mewtwo.
You stepped closer slowly, cautiously, with a mix of awe, wonder, and horror. And as you stopped in front of the tank, your horreur increased at the sight of Mewtwo's open eyes following you. It was alive... Alive and stuck, kept in this tank.
Your heart broke, it was so wrong. This being, it looked like nothing you had ever seen before. It didnt look like any Pokémon you had ever seen, too close to human beings, but yet not completely being one.
