Ranking The Big Bang Theory Girls Based on Their Character Development

The Big Bang Theory is known for its quirky male characters, the main quartet and more, but the women of the show deserve no less attention. While just as quirky in their own way as their male counterparts, they have managed to become fan favorites for many reasons. And one of them is personal character development.

However, while all of them have changed tremendously, some of the girls have shown even more significant growth. So let's see how we can rank their character development from season 1 to season 12.

1. Penny: The Ultimate Growth Story

Penny starts off as the stereotypical "girl next door" and struggling actress. Over time, however, she transforms into one of the show’s most well-rounded characters. She goes from working as a waitress to becoming a successful pharmaceutical sales rep.

Beyond her career, Penny matures emotionally, particularly in her relationship with Leonard, which progresses from awkward beginnings to a loving marriage. Penny’s evolution from a girl unsure of her place to a confident, successful woman makes her the character with the most remarkable growth.

2. Amy Farrah Fowler: Nerdy Queen

Amy’s journey is one of the most rewarding ones as well. Introduced as Sheldon’s socially awkward, "female counterpart," Amy begins as a nearly robotic character but gradually becomes a more emotionally intelligent woman.

As her relationship with Sheldon deepens, Amy finds her own identity, becoming a confident person with self respect. And needless to say, at the series finale she is the one winning the Nobel!

3. Bernadette Rostenkowski: Nice Try

Bernadette is probably the character whose inner growth has been less obvious. She begins the show as an already intelligent microbiologist who knows her place in the world, seemingly sweet, but unapologetic and strong. However, her marriage to Howard helps round her out and soften her, making her not only a boss but also a caring wife and mother.
