Growing up half-starved on the mean streets of Los Angeles, Razor spent her childhood fighting for everything she has. Her short stature made her an easy target for the neighborhood thugs, but that only made her fight twice as hard—taking out all her rage and aggression, as she destroyed them with her carefully honed street-fighting skills. The scrappy child has since grown into a cold and emotionless adult, cutting through her opponents and doing whatever it takes to survive. In need of an ally in this cutthroat world, Razor enlisted the unhinged Fury to fight by her side, forming the intimidating twosome The Psycho Sisters.
