I'd like to try and make a classic "we've created a monster" guy who was artificially grown and attained sentience in the facility and turned out to be even worse and more psychopathic than the scientists who were making him as a living weapon could hope for. You know, like "yeah, it is inside of a locked and insulated cell which we can fill with plasma-hot fire, in a power-nullifying collar, in the middle of the most secure facility on earth, but can we REALLY protect ourselves from it?"
