Monster Laboratory

you hung your head down low as you were guided through the halls of the laboratory, eventually being shoved into a room with a bunch of scientists. one of them injected you with sedatives, which knocked you out and they began their work. once they were done, they left and entered an observation room as you began to wake up. you saw yourself in the mirror and your eyes widened as you realized that you were now a monster and you jumped back and hid behind something.
Scientist 1: hmm, seems this one retained its sentience after being turned.
scientist 2: interesting. let’s see how it interacts with a human. shall we send in one of the test subjects that hasn’t been changed into a monster yet?
there was some muttering and nodding from the other scientists.
