Switchblade is an example of one of the many surviving non-mutants living in underground cities. Here, chaotic living conditions have bred a new kind of gangster, vaguely reminiscent of the pre-holocaust mafia but coupled with dangerous and often untested biotechnology. An avid enthusiast of illegal bioenhancements, Switchblade is an extra-fast and extra-deadly predator. And did I mention that he's slightly going insane because of his enhancements?
