Bourbon

Bourbon, also known as the "Snake Charmer", is candidate #103 in the 287th Hunter Exam. He is a skilled snake charmer and was a Hunter Exam veteran taking the Hunter Exam many times before. Bourbon is able to control a large number of snakes and force them to do his bidding. They will follow his orders even while he sleeps, or after his death. It's unknown if Bourbon has knowledge in the medical field since he was carrying anti-venom with him, though this was probably a safety measure for himself and used as a bargaining chip for his victims.
