10 Characters Who Were Never Meant to Be Popular—But Became Icons

Some characters start as minor players in their stories, meant to fade into the background after a brief appearance. But every now and then, a character captures hearts, defies expectations, and becomes a cultural legend, proving that sometimes the underdog steals the show.

I’ve rounded up 10 characters who were never intended to be stars but ended up as icons. These accidental heroes, villains, and sidekicks show how unpredictable storytelling can be, and I’m excited to share their journeys.

10. Mike Ehrmantraut – ‘Breaking Bad’ (2008-2013) and ‘Better Call Saul’ (2015-2022)

Mike, played by Jonathan Banks, was created as a last-minute fix when Saul Goodman’s actor, Bob Odenkirk, had scheduling conflicts. Introduced as a gruff fixer in ‘Breaking Bad’, he was meant for a brief role but became a fan favorite for his calm, no-nonsense vibe.

His complex backstory and moral code shone in ‘Better Call Saul’, making him a standout. Rewatching reveals the depth of Mike’s quiet strength, cementing his iconic status.

9. Topanga Lawrence – ‘Boy Meets World’ (1993-2000)

Danielle Fishel’s Topanga was a quirky, temporary love interest for Cory in early episodes. Initially a weird hippie girl, she was nearly written off but grew into the show’s heart, becoming Cory’s soulmate and a 90s teen idol.

Her charm and grounded growth made her a beloved figure. Fans still rewatch for Topanga’s witty lines and romantic arc, proving her lasting appeal.

8. Odafin ‘Fin’ Tutuola – ‘Law & Order: Special Victims Unit’ (1999-2025)

Ice-T’s Fin was brought in for a four-episode arc in season two as a temporary detective. His tough yet relatable personality clicked with audiences, keeping him on the show for over two decades.

Fin’s dry humor and loyalty make him a rewatch staple. His unexpected rise from guest star to core cast member shows his undeniable charisma.

7. President Josiah Bartlet – ‘The West Wing’ (1999-2006)

Martin Sheen’s President Bartlet was meant to be a recurring figure, not the main focus of ‘The West Wing’. Planned for just a few episodes, his commanding presence and sharp wit made him the show’s soul.

His blend of idealism and flaws keeps fans coming back. Rewatching highlights Bartlet’s inspiring speeches, making him a TV president for the ages.

6. Maris Crane – ‘Frasier’ (1993-2004)

Maris, Niles Crane’s unseen wife in ‘Frasier’, was never meant to be a major player. Her absurd, oft-mentioned quirks—like being impossibly thin and eccentric—turned her into a running gag that fans adored.

The mystery of her absence made her larger than life. Rewatching ‘Frasier’ episodes, you catch new, hilarious Maris references every time.

5. Daryl Dixon – ‘The Walking Dead’ (2010-2022)

Norman Reedus’ Daryl was created for the show, not the comics, after Reedus auditioned for another role. A rugged survivor with a crossbow, he was meant as a minor character but became a fan-favorite badass.

His emotional depth and loyalty keep viewers hooked. Daryl’s rise to starring in spin-offs proves his iconic draw.

4. Castiel – ‘Supernatural’ (2005-2020)

Misha Collins’ angel Castiel was introduced in season four to kick off an apocalypse arc, meant to last a few episodes. His deadpan humor and loyalty to the Winchesters made him a beloved mainstay for 12 seasons.

Fans rewatch for Castiel’s awkward charm and epic moments. His unexpected journey from guest star to core character is pure magic.

3. Mrs. Wolowitz – ‘The Big Bang Theory’ (2007-2019)

Voiced by Carol Ann Susi, Mrs. Wolowitz was an unseen, loud-mouthed mom meant for occasional comic relief. Her over-the-top yelling and quirky bond with Howard became a fan-favorite running joke.

Her larger-than-life presence shines in every rewatch. Even after Susi’s passing, Mrs. Wolowitz remains a sitcom legend.

2. Spike – ‘Buffy the Vampire Slayer’ (1997-2003)

James Marsters’ Spike was planned as a short-term villain for Buffy to defeat. His punk-rock charisma and complex arc—from foe to lover—made him a breakout star, even spawning a role in the ‘Angel’ spin-off.

His wit and redemption arc make rewatching a joy. Spike’s journey from disposable baddie to icon is a fan-driven triumph.

1. Captain Jack Sparrow – ‘Pirates of the Caribbean’ (2003-2017)

Johnny Depp’s Jack Sparrow was meant to be a supporting rogue in the first ‘Pirates’ film, with the focus on Will and Elizabeth. His quirky, rum-loving pirate stole every scene, becoming the franchise’s heart.

Depp’s unpredictable energy makes Jack endlessly rewatchable. His rise from side character to global icon is a testament to pure charisma.
