10 TV Side Characters Who Had Serious Main Character Energy

Sometimes, supporting characters in TV shows become more popular than the main stars. Even in comedies like Brooklyn Nine-Nine, where the whole cast is meant to be funny, side characters can stand out and become the most memorable. A great actor can turn any supporting role into a fan favorite, no matter the genre.

Sometimes a character becomes so popular, they get their own show! Think of Saul Goodman from Breaking Bad or Frasier Crane from Cheers – these characters were so beloved, they helped shape television as we know it.

Even if they don’t get their own show, supporting characters can still become incredibly important to a TV series, becoming regular fixtures. That’s a sign of a truly compelling character.

Lalo Salamanca – Better Call Saul

Lalo Salamanca, as portrayed by Tony Dalton in Better Call Saul, is a standout villain, even within a franchise full of memorable antagonists. He’s a compelling and dangerous character because he appears calm and collected, masking a truly calculating and ruthless mind. This makes him a far greater threat than most people suspect.

Lalo Salamanca immediately makes each scene more intense when he’s on screen. He’s charismatic and clever, and often steals the show, even from well-established characters like Mike and Gus.

Season 5 is when Lalo Salamanca really comes into his own. Once he arrives in Albuquerque, he quickly causes trouble by looking into Gus Fring’s hidden dealings and disrupting the existing power structure of the cartel. The intense interrogation scene in the episode “Bad Choice Road,” where he confronts Jimmy and Kim Wexler, firmly establishes him as one of the most frightening characters in the series.

While Better Call Saul primarily follows Jimmy McGill’s transformation into Saul Goodman, the death of Lalo Salamanca in the final episodes strongly connects the show to Breaking Bad. Lalo’s captivating presence often made him the most interesting character to watch.

Schmidt – New Girl

Whether you love him or not, Max Greenfield’s character Schmidt goes through a huge transformation throughout New Girl. He’s often the one driving the comedy, seamlessly switching between being the funny guy and the serious one, and really keeps the show’s humor going.

Over the course of the show, we discover what shaped Schmidt into the person he is. We see how he changed from a somewhat awkward and heavier college student – known as “Fat Schmidt” – into a very polished and ambitious adult. Though he comes across as incredibly confident and focused on success as a marketing professional, Schmidt’s over-the-top personality actually hides a surprisingly sensitive side.

Throughout the series, Schmidt gradually becomes more open and vulnerable, especially with Cece. By season 5 of New Girl, he’s even encouraging Nick to grow up and take responsibility, as seen in the episode “Road Trip.” By the final season, Schmidt has fully embraced his role as a dedicated stay-at-home dad, finding joy in daily life with his daughter Ruth while Cece focuses on her career.

Max Greenfield’s work on the show was highly praised, earning him an Emmy nomination for Best Supporting Actor in a Comedy Series in 2012. His character, Schmidt, brings a lot of energy and compelling emotional depth to the show, making him a standout. While the series centers on Jessica Day, many viewers find Schmidt’s personal journey the most captivating.

Daryl Dixon – The Walking Dead

Daryl Dixon is a great example of a supporting character becoming a major star. He wasn’t part of the original The Walking Dead comics, but he quickly became a fan favorite. Introduced in the first season as the unpredictable brother of Merle, Daryl was one of the first characters created specifically for the TV show.

Norman Reedus quickly became essential to the show as Daryl, leading writers to give him a much larger role. He brilliantly portrayed Daryl’s development from a wary loner into a fiercely devoted member of the group, giving the character a storyline as compelling as those of the show’s main stars.

The episode “Chupacabra” from season two, with Daryl’s determined search for Sophia, really showed how his hidden emotional side became a powerful part of the show’s drama. As the series went on, Daryl often served as a key source of morality and stability within the story.

Norman Reedus became so popular as Daryl Dixon that he got his own show, The Walking Dead: Daryl Dixon, which he just finished filming the last season of. This new series demonstrates that Daryl Dixon was always a central character with a story as important as the main hero in The Walking Dead.

Spike – Buffy the Vampire Slayer

Spike first appeared in season 2 of Buffy the Vampire Slayer and quickly won over fans. He became so popular that he later played a major role in the spin-off show, Angel.

I have to say, I was thrilled when Spike stuck around on the show! He wasn’t supposed to be a permanent character, but the fans – including me! – just loved him. What really got me was how much more there was to him than just being a bad guy. Episodes like “Fool for Love” showed us his heartbreaking history as William the Bloody, and it explained why he acted the way he did. It proved he was a really complex character, and it made him so much more interesting.

Spike was a compelling character because of his sharp wit, rebellious style, and complex connection with Buffy. Despite some very controversial storylines, particularly in the episode “Seeing Red,” he remained popular, largely due to James Marsters’ acting. Marsters brought a vulnerable, human side to the traditionally villainous vampire.

I’ll never forget watching Spike evolve from a total bad guy into someone you actually rooted for. By the end of Buffy, his selfless sacrifice really cemented him as one of the most memorable characters on television, in my opinion. He really became an icon.

Erica Sinclair – Stranger Things

Erica Sinclair starts out as Lucas’s witty little sister when she’s introduced in season 2 of Stranger Things. But thanks to Priah Ferguson’s fantastic acting, she quickly becomes one of the show’s most fun and memorable characters.

Erica is a memorable character in a show full of scary supernatural events, thanks to her confident personality and sharp wit. In the third season, she plays a key role in the story involving the “Scoops Troop,” assisting them as they investigate a hidden Russian base under the Starcourt Mall. She’s also known for her funny and iconic lines, like “You can’t spell America without Erica.”

By the fourth season, Erica had become a fan favorite and a main character. She proved to be a skilled Dungeons & Dragons player, often outperforming the boys in their games. Later, in the second part of the season, she bravely accompanied the group to the Creel house, helping them try to capture Vecna.

At first, Erica seemed like she was just there for a few laughs, but Priah Ferguson quickly made her so much more! She really developed Erica into someone who felt like a true part of the main group. Every time she’s on screen, her smarts, confidence, and perfect comedic timing just grab your attention – she’s fantastic!

The Janitor – Scrubs

The Janitor from the TV show Scrubs is a fantastic example of a character who seems like the main character, even though he isn’t. Actor Neil Flynn plays him as a somewhat grumpy janitor who initially develops a strange dislike for the show’s main character, J.D., right from the start.

Neil Flynn was a naturally gifted improviser as an actor. The show’s writers frequently allowed him to create his own lines instead of sticking strictly to the script. This ability quickly made his character, the Janitor, a fan favorite and one of the series’ best.

The Janitor gradually became a key character on the show. His ongoing feud with J.D., his bizarre stories that blurred the line between reality and imagination, and his habit of forgetting everyone’s names often took the show’s comedy to a hilariously absurd level.

The Janitor’s unpredictable behavior provided both humor and opportunities for surprisingly emotional moments. As viewers began requesting more of his scenes, the writers developed his character, revealing his hidden vulnerabilities in season 5’s “His Story III.” Ultimately, thanks to the actor’s talent, the Janitor became a beloved character among fans.

Titus Andromedon – Unbreakable Kimmy Schmidt

Titus Andromedon often steals the show in Unbreakable Kimmy Schmidt. This is due both to the character’s inherent flamboyance and the incredibly talented performance by actor Tituss Burgess.

I’m a huge fan of Titus on the show – he’s this incredibly dramatic aspiring performer, and honestly, he’s responsible for some of the funniest, most over-the-top scenes. His musical numbers are legendary! I’ll never forget his performance of “Peeno Noir” in the first season – it totally blew up online! And then in season three, his take on Beyoncé’s “Hold Up” video was just brilliant. Those moments really define the show for me.

Titus’s over-the-top personality, unwavering confidence, and constant ambition to be a star create a funny contrast with Kimmy’s genuinely positive outlook.

Tituss Burgess received four Emmy nominations for his supporting role as Titus Andromedon, and many believe his character—with its detailed history and flamboyant, theatrical style—is strong enough to carry its own show.

Tahani Al-Jamil – The Good Place

Jameela Jamil plays Tahani, who begins the show The Good Place as a somewhat arrogant and boastful philanthropist. She’s very focused on mentioning her famous friends and holding onto the privileged lifestyle she enjoyed when she was alive.

Throughout the series, Tahani’s hidden insecurities and long-standing competition with her sister, Kamilah, add emotional depth to her story. Episodes, such as “Fractured Inheritance,” reveal the challenges she faced growing up with demanding parents, ultimately turning what seemed like a superficial character into someone relatable and deserving of sympathy.

Tahani’s journey of self-discovery is one of the most rewarding parts of the show. Over the seasons, we watch her overcome insecurities, accept herself for who she is, and repair her relationship with her sister. By the end, she’s finally confident and genuine, even taking on a major role as an architect in the afterlife’s redesigned system.

Even though ‘The Good Place’ features a group of main characters, Tahani experiences the most significant development. The show delves into her past more than the others, giving us a better understanding of why she is the way she is, and that makes viewers really care about her journey.

Ron Swanson – Parks and Recreation

Ron Swanson from the show Parks and Recreation is one of the most recognizable sitcom characters ever. Actor Nick Offerman plays Ron as the director of Pawnee’s Parks Department, and a staunch libertarian. He constantly clashes with Leslie Knope, because despite working for the government, he actually believes government shouldn’t exist.

Ron Swanson became one of the show’s most memorable characters thanks to Nick Offerman’s dry humor, passion for woodworking, and love of breakfast. Offerman portrayed the role so convincingly that it’s often hard to tell where the character ends and the actor begins. While Offerman himself enjoys woodworking and a good drink, his personal views are actually quite progressive, a contrast to the staunchly conservative beliefs of his character.

His portrayal of Ron was crucial to his later success in film and television, and it brought him a lot of recognition. He won a Critics’ Choice Television Award for Best Supporting Actor in a Comedy Series for his work.

I always loved Leslie Knope as the heart of the show, but honestly, Ron Swanson was such a fantastic character that he could have easily carried his own series. His whole outlook on life was so distinct, and watching him slowly become friends with everyone was a really compelling story in itself.

Cassie Howard – Euphoria

Though Euphoria centers on Rue Bennett’s battle with addiction, Cassie Howard frequently drives the show’s most dramatic and emotional plots. Actress Sydney Sweeney plays Cassie, and her character’s openness and impulsive choices make her particularly captivating to watch.

Even with a large cast of interesting characters, Cassie’s storylines consistently drive the show’s emotional core. She’s a character deeply driven by a need to feel accepted and often finds herself in difficult romantic situations.

Her hidden romance with Nate Jacobs caused a major fight in season two. Her intense emotional reaction during Lexi’s play, “The Theater and Its Double,” was a particularly memorable and discussed scene.

Season 2 of Euphoria built a lot of its drama around Cassie’s struggles with her friendships and her increasingly risky behavior, and it seems like that trend will continue in season 3.
