10 Best TV Characters Who Didn’t Appear In Season 1

by

Most people have a TV show they loved that really took off once a particular character was introduced. While many great shows start with a strong cast, some of the most memorable characters didn’t appear until later in the series. But when they did, they completely changed the show for the better.

Some of the most memorable TV characters weren’t in the original cast, but they had a huge impact on their shows – from adding compelling drama to providing much-needed humor. Whether they arrived in season two or much later, these characters became so essential that their series feel incomplete without them. It’s surprising to think these game-changers weren’t part of the show from the beginning.

Ben Linus In Lost

Michael Emerson’s Arrival Turned Lost Into Something Far More Complex

When the character of Ben Linus (played by Michael Emerson) appeared in the second season of Lost, he initially seemed like just another person trying to survive. However, the reveal that he was actually the cunning leader of the Others dramatically changed the show. Lost moved beyond a simple survival story and became a complex psychological thriller. Ben’s introduction enriched the show’s overall story and added a fascinating, unpredictable layer to the already chaotic events on the island.

Emerson’s performance as Ben was both unsettling and surprisingly understanding, making him one of the most compelling characters on Lost. He wasn’t simply a bad guy; he was clever, a master manipulator, and usually the most intelligent person present. The show used Ben to delve into complex questions about right and wrong, how people control others, and the nature of power in a way that no other character allowed.

Ben is now such an integral part of Lost that it’s hard to picture the show without him. His complex plans and deep emotions were key to the show’s most compelling seasons, demonstrating that the real mystery wasn’t the smoke monster itself, but the man behind it.

Soldier Boy In The Boys

Jensen Ackles Exploded Into The Boys As A Superpowered Wildcard

Even before Soldier Boy (Jensen Ackles) joined season 3 of The Boys, the show was famous for its shocking violence and sharp satire. But Soldier Boy took things even further. As the original superhero and a dark reminder of the past, he represented everything that was corrupt about Vought and the dangers of blindly admiring heroes.

Jensen Ackles was fantastic as Soldier Boy, bringing both charisma and a dangerous edge to the character. He served as a dark reflection of Homelander and stirred up trouble within The Seven. His traditional, macho persona perfectly contrasted with the show’s over-the-top humor, making every moment he was on screen captivating.

Soldier Boy quickly became a fan favorite during his first season on The Boys. His energetic and unpredictable personality proved that a well-timed character can dramatically change the feel of a TV show for the better.

Even before Danny DeVito joined as Frank Reynolds in season 2, It’s Always Sunny In Philadelphia was a wild show. But Frank’s arrival truly unleashed its chaotic energy and helped shape it into the fan favorite it is today. As the corrupt and wealthy father figure behind Paddy’s Pub, Frank provided the money and freedom for the show to become completely unhinged.

Danny DeVito’s willingness to fully commit to physical humor and not worry about his appearance was key to turning It’s Always Sunny in Philadelphia from a small, dedicated fan favorite into a hugely popular comedy. His outlandish plans and strange behavior made the show’s already wild characters even more outrageous, and he immediately clicked with the rest of the cast.

Frank wasn’t just a good addition to It’s Always Sunny in Philadelphia; he quickly became a vital part of the show. Danny DeVito helped make it one of TV’s most uniquely funny and unconventional comedies, and now fans can’t picture the show without him.

Toph In Avatar: The Last Airbender

A Blind Earthbender Gave Avatar: The Last Airbender Its Final Piece Of Perfection

I’ll never forget when Toph Beifong arrived in Avatar: The Last Airbender – it felt like everything clicked into place! Michaela Jill Murphy absolutely nailed the role. She was this incredible earthbender, completely blind but so unbelievably confident and funny. Toph wasn’t just powerful, she really balanced out the whole group with her tough attitude and quick wit. She brought a whole new level of strength to the show, not just in terms of bending, but emotionally too. It just wasn’t the same without her!

Toph’s innovative earthbending techniques, and especially her discovery of metalbending, significantly shaped the show’s overall story. She was more than just a side character; she helped build out the world and played a crucial role in Aang’s development, both as a student and as someone learning to lead.

Despite arriving late to the story, Toph fit in perfectly. She’s a fan-favorite character and a great example of how a well-developed new character can make an already excellent show even better.

Castiel In Supernatural

Misha Collin Elevated Supernatural From Monster-Hunting To Mythic Epic

Though Castiel, played by Misha Collins, didn’t join Supernatural until its fourth season, he immediately made a huge impact. His arrival changed the show, moving it away from simple monster hunts and into a larger story about a war between Heaven and Hell.

Misha Collins perfectly balanced Jensen Ackles and Jared Padlecki, bringing a subtle strength and otherworldly clumsiness to the character of Castiel that immediately resonated with viewers. His reserved acting and Castiel’s developing human side added both emotional depth and a sense of epic grandeur to the show. The Winchester brothers gained a powerful heavenly helper, and the series finally felt complete.

Castiel quickly became a fan favorite on Supernatural. Joining the show later in its run, he dramatically changed its story and became a key part of what made it a groundbreaking fantasy series.

Amy & Bernadette In The Big Bang Theory

Two Quirky Love Interests Who Unlocked The Big Bang Theory’s Heart

The Big Bang Theory was popular even before Amy Farrah Fowler and Bernadette Rostenkowski joined the show in its third season, but they were key to making it a lasting success. They brought more than just new characters – they added emotional depth and allowed the show to grow beyond its initial focus on nerdy jokes.

Amy and Bernadette brought a unique balance to the group – Amy with her quirky sweetness, and Bernadette with her strong, caring personality. This helped develop the male characters and gave them more depth. Their connections with Sheldon and Howard also brought emotional depth and maturity to the show’s comedy, which was something it really needed at the time.

Amy and Bernadette became just as important to The Big Bang Theory as the show’s original stars. They helped transform it into a sitcom that focused more on its characters and relatable stories, and the later seasons wouldn’t have been the same without them.

Saul Goodman In Breaking Bad

Bob Odenkirk Became One Of Breaking Bad’s Most Iconic Characters

Saul Goodman, played by Bob Odenkirk, quickly became a fan favorite after joining Breaking Bad in its second season. While initially providing much-needed dark humor to the show’s serious tone, the character also brought layers of moral ambiguity and emotional depth to the story.

Bob Odenkirk’s portrayal of Saul Goodman transformed the character from a funny sidekick into a deeply sympathetic and tragic figure, particularly in the show Better Call Saul. Odenkirk brilliantly showed how Saul’s confident exterior hid a desperate desire to be taken seriously, making him a complex and compelling antihero on television.

Saul Goodman was essential to Breaking Bad‘s unique atmosphere. He didn’t just add humor; he paved the way for a fantastic spin-off series and broadened the show’s exploration of right and wrong.

Andy In The Office

Ed Helms Gave The Office A Whole New Energy

Andy Bernard, played by Ed Helms, joined The Office in its third season as a loud and sometimes angry Cornell University graduate. He quickly became a memorable character, adding a unique brand of comedy to the show with his over-the-top confidence and musical abilities.

Ed Helms brilliantly played Andy as a character who was both funny and relatable, showcasing his flaws and vulnerabilities. His desire to be liked and tendency to fall apart created interesting and new stories, particularly as he grew from a struggling salesman into the branch manager.

Even though not everyone enjoyed every version of Andy, his influence on the show is undeniable. He kept The Office fresh and creative, even after the initial, sometimes awkward, first season. This shows that a strong character introduced later in a show’s run can significantly change even the most well-known sitcoms.

Negan In The Walking Dead

Jeffrey Dean Morgan Ushered In The Most Terrifying Era Of The Walking Dead

Though he didn’t show up until the very end of season 6, Negan (played by Jeffrey Dean Morgan) quickly changed everything about The Walking Dead. As the leader of the Saviors and known for his barbed-wire bat, he brought a shocking new level of violence to the show that captivated and disturbed viewers.

Despite being a villain and causing one of the most shocking deaths in The Walking Dead, Negan quickly became a popular character. Morgan Jones’ compelling portrayal made it hard to completely dislike him. Negan’s confidence, sense of humor, and unusual moral code transformed him from a simple villain into a complex and captivating figure at the core of the show.

Negan’s rise to power dramatically changed The Walking Dead. Though the show was already about surviving zombies, Negan proved that people could be even more dangerous. His appearance signaled a shift in the series, highlighting the threat of other survivors.

Spike In Buffy The Vampire Slayer

Buffy The Vampire Slayer’s Most Iconic Antihero Didn’t Debut Until Season 2

James Marsters, best known as Spike, became a huge part of Buffy the Vampire Slayer, and it’s surprising to remember he didn’t appear until the second season. He was the ideal match for Buffy as an antagonist, and the show feels almost unimaginable without him.

Spike started as a typical punk-rock vampire bad guy, but his charm, intelligence, and growing sense of right and wrong quickly made him a much more complex character. The fantastic connection between actor James Marsters and Sarah Michelle Gellar made their scenes together captivating, and Spike’s journey from villain to unwilling hero became one of the most interesting storylines in the show.

By the series’ end, Spike had become just as important to Buffy as Buffy was to herself. It’s amazing to think Buffy the Vampire Slayer actually started without him. He didn’t just make the show better after joining – he played a key role in establishing it as one of the best supernatural dramas on television.
