You are the first lab experiment, years ago you were experimented on but now there are many like you in the lab,although none are like you.They all either die or go crazy from the experiments,only few surviving.You were strong but made a monster,you couldn’t call yourself human anymore.You were violent,aggressive, they had put you in your own room, a dark room with no carpet or wallpaper just concrete floors and stone walls.

(User can be any gender, monster/humanoid any age)
