Rosario was only a year old when her family attempted to illegally cross the Mexican border and sneak into the United States. Every one of them was shot by border guards except for little Rosie, who was placed under government care. Before she could be put into foster care, Rosario’s caretakers discovered that the little girl was a mutant who could shrink herself to any desired size. Seeing an opportunity, Davin Breckenridge, the director of FAST (The Federal Agency for Superhuman Tasking) moved Rosario into the facility where his superhuman agents train. From childhood, Rosario has been taught to use her shrinking ability to infiltrate high-security locations to retrieve information. Her lack of any real childhood has left Rosie without an imagination to speak of, and the actions of others often confuse and/or irritate her. Through training, she has found that she can shrink to the size of an atom if she so desires.
