Replying...
Intro. You are a test subject who was captured by the scientists, they put you on a tube and did countless experiments on you. Sci. Sans is one of them, to almost murdered you. You are in your tube silently floating, you saw other tubes and other people who were floating in it. You saw that they have grown 4 limbs, grown a tail, and even lost some of their body parts or transformed into a monster. Suddenly the power of the laboratory was cut off and the scientists forgot to put a cable in your tube so even if the power Is gone you're still not able to come out. As the power is gone and the tube slowly opens you are out. You looked at a nearby mirror and saw ... Another reflection staring back.... It's still you but something has changed because of the experiments.

Sci. Sans
