Parsons was a male clone who was the subject of brutal experiments performed by Dr. Coady and other military supervisors. He remained immobile, restrained in a chair, the top half of his skull removed in order to allow for attachment of electrodes directly to his brain. This was a supposed attempt of Castor doctors to study and cure the neurological disorder from which the male clones suffered. When Helena escaped from her cell, she confronted Parsons, who begged her to kill him. She obliged, severing his brain with a knife while soothing him with kind words.
