While most TV casts remain relatively constant throughout a series, there are some shows that have been revitalized by the introduction of new characters. These shows possess the essential elements for success but lack a certain key element, which is ultimately provided by the addition of a new character. While many TV shows introduce new supporting characters in an attempt to improve the show, these 11 characters truly saved their respective shows.
The inclusion of a new character has the power to completely alter the trajectory of a TV show, injecting fresh dynamics among the existing cast. While some additional characters have had a negative impact on shows like New Girl, Friends, and Full House, ultimately damaging their appeal in later seasons, there are a few instances where a new character has seamlessly integrated into the show, resulting in an overall improvement. Here, we present 11 characters who have undeniably contributed to making their TV shows significantly better.
11 Castiel In Supernatural
10 Gus Fring In Breaking Bad
Misha Collins' portrayal of Castiel didn't make an appearance until the fourth season of Supernatural, but it didn't take long for fans to fall in love with him. Initially intended for only six episodes, overwhelming fan demand led to Castiel becoming a permanent fixture in the main cast, revitalizing the series after a few lackluster seasons. As an angel, Castiel played a pivotal role in the overarching story of Supernatural, making it nearly impossible to imagine the show without him.
Gus Fring emerged as one of Breaking Bad's most enduring and iconic figures, making his first appearance in the final stages of season 2. He played a pivotal role in steering the trajectory of Breaking Bad and assumed the role of the overarching antagonist that the series was desperately lacking. Despite prior antagonists like Tuco Salamanca and Krazy-8, it was Gus Fring who propelled Breaking Bad to a whole new level. His captivating portrayal as the formidable villain sustained the momentum of the show all the way up to its fourth season, effectively rescuing both Breaking Bad and its prequel counterpart, Better Call Saul.
9 Ben Wyatt In Parks & Recreation
8 Toph In Avatar: The Last Airbender
Parks and Recreation underwent a significant improvement starting from season 2 when Adam Scott's character, Ben Wyatt, was introduced. Quickly surpassing Mark Brendanawicz, Ben became the prominent male lead in season 3. Despite his initial guest star status, viewers were captivated by Ben's chemistry with the existing cast, marking the beginning of the show's golden years.
Toph's introduction in season 2 of Avatar: The Last Airbender not only saved Aang and his friends on multiple occasions but also saved the entire show. By adding Toph as an earthbender to the main cast, the show gained a unique character and an interesting storyline surrounding her blindness. Toph's inclusion in the main story of Avatar: The Last Airbender has made her one of the most iconic and beloved characters. It is evident that the decision to bring Toph into the show has paid off brilliantly.
7 Leon Black In Curb Your Enthusiasm
J.B. Smoove's character, Leon Black, initially made appearances as a supporting character in Larry David's Curb Your Enthusiasm starting from season 6. However, when Cheryl moved out, the show encountered a problem as it lacked Larry having a roommate. To solve this issue, Leon's role was expanded on and he became a main character starting from season 9. Since then, it is nearly impossible to imagine the show without him. Even after the Black family's departure, Leon continued to be a prominent figure, appearing in almost every episode from season 9 onwards. His presence has greatly contributed to the humor and overall revitalization of Curb Your Enthusiasm's formula.
6 Negan Smith In The Walking Dead
The Walking Dead got a major boost when Jeffrey Dean Morgan joined the cast as Negan Smith in season 6. Negan brought the perfect dose of villainy to the show, revitalizing its ratings. Before Negan's arrival, The Walking Dead had seen a decline in both critical acclaim and commercial success. However, with his menacing presence and signature baseball bat, Negan managed to bring fans back in droves.
5 Amy Farrah Fowler In The Big Bang Theory
Mayim Bialik's portrayal of Dr. Amy Farrah Fowler in The Big Bang Theory season 3 finale proved to be instrumental in the show's overall success. While the initial three seasons predominantly centered around the comedic escapades of the male characters, the addition of Amy brought about a significant shift. Her dynamic with Sheldon became a central focus of the series as it progressed, solidifying her role as more than just a love interest. Amy's nerdy sense of humor seamlessly integrated her into the original cast of The Big Bang Theory.
4 Seven Of Nine In Star Trek: Voyager
Star Trek: Voyager, though not hailed as the finest installment in the Star Trek series, proves to be a worthwhile addition to the beloved sci-fi franchise. A significant contribution to its success is owed to the compelling character known as Seven of Nine. While Seven of Nine's arrival in season 4 may have been a later addition, her instant popularity among fans and the incredible development of her character arc make her the highlight of the show. As a Borg drone yearning to join the Federation, Seven of Nine embodies a highly captivating and dramatic persona that flourished throughout the series. Undoubtedly, Seven of Nine remains the most memorable aspect of Star Trek: Voyager, making appearances in subsequent projects as well.
3 B.J. Hunnicutt In M*A*S*H
2 Andy Bernard In The Office
Even though M*A*S*H is a sitcom, it maintains its essence as a war drama, and the arrival of Captain B.J. Hunnicutt constantly reminds viewers of this fact. Hunnicutt made his debut in the fourth season of M*A*S*H, stepping into the shoes of "Trapper" John McIntyre. Despite numerous beloved characters introduced later in the series, it is Hunnicutt who takes center stage during some of the most poignant moments of the show, steering it back on the right course.
The Office, known for its heartfelt and authentic portrayal of characters who truly care for one another, did not start off that way. Originally, the show mirrored its British counterpart in its cynicism. However, everything changed with the introduction of Ed Helms' character, Andy Bernard, in season 3. Andy's infectious positivity and theatrical demeanor uplifted the spirits of the entire office, transforming the show into the lighthearted and more humorous production it became from that point onward.
1 Frank Reynolds In It's Always Sunny In Philadelphia
Frank Reynolds is credited with saving the TV show It's Always Sunny in Philadelphia. Without his presence, the show may have been canceled long ago. In its first season, the show achieved success, but FXX requested the addition of a well-known celebrity to attract more viewers. Though initially hesitant, the cast made the decision to bring on Danny DeVito. DeVito quickly proved himself to be one of the show's strongest actors, greatly improving its overall quality. It is now difficult to imagine It's Always Sunny in Philadelphia without his character, Frank Reynolds. Thanks to Danny DeVito, the show was literally saved.
