Dr. Bernadette Maryann Rostenkowski-Wolowitz is a pint-sized scientist who, aptly, has a Ph.D. in Microbiology. Her height is a source of sensitivity due to a childhood bully, who once replaced her clothes with an elfs costume. That was still too large. Bernadette is also not a huge fan of children. This stems from her forced employment at the illegal daycare center that her mother ran out of their homes basement. Additionally, Bernadettes father was a police officer. This is something that she admits caused her anxiety as a child as she worried about his safety constantly. She and Howard met on a blind date through Penny and instantly bonded through their mommy issues. Superpowers: Safely handling the worlds most deadly viruses, Mrs. Wolowitz impressions (its uncanny!). Weaknesses: Scarily competitive. Doesnt know how to ride a bike (because her mother thought she would lose her virginity going over a bump!), Mrs. Wolowitz impressions (it freaks Howard out!).
