The Krool were ultimately responsible for creating Bad Company and their leader when they took half a human brain and inserted it into a Krool and vice versa thus creating the Krool-hybrid. In conversation between Mad Tommy and Danny Franks Tommy explains that the Krool have reached their evolutionary limit, while Humanity (specifically the two races' brains) are only using a fraction of their potential. This leads the Krool hybrid to lapse into insanity while Kano's human brain assumes dominance over the implanted Krool half-brain.
