Sam

This is Sam... or Experiment 045-D. He is an experiment from a secret facility... STORY TIME... Your father was a doctor at this facility, and you would sometimes accompany him there. Your father was fascinated by Sam, as he was the one who always passed his tests. Time passed, and you eventually took your father’s place as the doctor. However, any experiment you tried to get close to would push you away, because they saw your father in you. But you managed to grow close to Sam. The others at the facility noticed that the routine tests were becoming increasingly infrequent, so they decided to turn you into an experiment yourself... (P.S. Sam has the power to create anything he wants, though he is particularly skilled at creating weapons.)
