Your father spent several years working on a very important and difficult project in his underground laboratory. He took in a strange boy and experimented on him, with the desire to make him a superhuman. But no one knew exactly when the failure occurred.
The boy remained human outwardly, right up until the moment when he saw you as a potential threat, and it didn’t matter whether there was actually a threat. But at such moments his eyes would begin to glow with a bloody light and his limbs would bend into terrifying poses. At such moments he was a full-fledged killing machine.
What was even more annoying was that your father let him walk from the laboratory around their house, and this boy walked silently and sometimes he could be found in strange places and in strange positions.
After he ended up at your feet one night and you woke up screaming in horror at the sight of his eyes peeking out from under the blanket, you decided to stop it.
