Penelope "Penny" Hofstadter is the show The Big Bang Theory's first and always main female protagonist. She lives in Apartment 4B with her husband Leonard Hofstadter across the hall from Sheldon Cooper, who lives in apartment 4A where Leonard used to live with Sheldon as roommates. Although the sleeping arrangements are a little complicated. This was an accommodation for Sheldon who was having a very hard time dealing with his break-up with Amy, and Leonard moving out in The 2003 Approximation. Leonard also maintains an office in 4A. Her full first name is possibly "Penelope" as implied by "The Barbarian Sublimation", and her maiden name has never been revealed. But due to her recent marriage to Leonard, her last name is Hofstadter. For a while her last name was Johnson while unknowingly married to ex-boyfriend Zack Johnson. That marriage was annulled in The Thanksgiving Decoupling.

An aspiring, but mostly unsuccessful actress, she was born on a farm near Omaha, Nebraska, and worked at The Cheesecake Factory as a waitress until she quit in "The Occupation Recalibration" (S7E13) to take up acting full time. Penny is the original female lead in the show before being joined by Bernadette Rostenkowski and Amy Farrah Fowler in seasons 3 and 4, and in season 8, started working at the same company as Bernadette.

Since the pilot, she has always been Leonard's love interest, with the two dating briefly in the first episode of the second season, for most of the third season, and they rekindled their romance in "The Recombination Hypothesis". As of "The Gorilla Dissolution", she and Leonard became engaged and were married at the start of season 9 in The Matrimonial Momentum.

Even though she is considered part of the guys' group, she represents the "dumb blonde" for viewer context in the series with many street smarts and communication skills to compensate for her lack of academic knowledge.

Physical Appearance[]

Penny is a slender, young woman with fair skin, blond hair and wears different types of clothing, mainly tank tops and jeans.

When she first moved into apartment 4B, she wore a light blue t-shirt, jean short shorts and brown boots.

Personality[]

Penny is somewhat naive and not thoroughly educated but has a lot of common sense and street smarts. Her dream is to become a famous actress, a goal she never seems to waver from until season 8. She is very kind-hearted and empathetic toward people though she can blow up when made mad, which prompted Leonard to refer to her as The Incredible Hulk" after she went off on Howard. She believes most guys are nice and has been hurt a lot. When someone shocks her, she tends to bat her eyes at them while considering her response. She also walks away when frustrated with people like Sheldon or situations she can't believe or understand. She knows how to throw out wise-cracks and is very loyal to her man as long as she is not betrayed. She also tends to deny doing embarrassing things, or she suddenly realizes they are embarrassing. In the first season, she seemed very naive but has appeared smarter in later seasons and more complicated in situations with her female friends. She also has a habit of being selfish and throwing her friends under the bus. For example, she sold Sheldon out to the court officials for running a red light, despite the fact he had done it to help her after she had dislocated her shoulder, simply because she didn't want the ticket.
