11 TV Characters Who Were Supposed to Be Temporary But Stole the Show

Imagine sitting at a writer's table, sketching out the next big TV show. You draw characters, envisioning some as short-lived plot movers—a bridge from storyline A to B and nothing more. Yet, occasionally, one of these so-called "temporary" characters takes on a life of their own, wooing viewers with charm, complexity, or sheer unpredictability. They leap from the margins to take center stage, becoming as essential as the leads you meticulously planned from day one. With indelible performances and magnetic presence, these characters showcase the beauty of television's unpredictable nature.

Let's embark on a journey through the world of television, where characters meant to be fleeting impressions morphed into resounding voices. Here are 11 TV characters who defied their temporary fates and became indispensable to their shows—stealing hearts, scenes, and perhaps unwittingly, the entire show.

1. Spike – Buffy the Vampire Slayer

Originally introduced as a one-shot villain in Buffy the Vampire Slayer, Spike, portrayed by James Marsters, was intended as a temporary antagonist. His devil-may-care attitude and enigmatic attraction resonated with viewers, so the show's creators extended his arc. Spike's evolution from villain to anti-hero to Buffy's complex love interest was a narrative masterstroke. His presence injected layers of tension and comedic relief, ultimately cementing his place as a fundamental part of the Buffyverse.

2. Steve Urkel – Family Matters

It’s hard to think of Family Matters without recalling the clumsy, nerdy, and lovable Steve Urkel, played by Jaleel White. Originally introduced as a guest character, Urkel’s quirky catchphrases and comedic blunders quickly made him a fan favorite. Producers recognized his potential and expanded his role significantly, even adapting the show's storylines to focus on his antics. Urkel not only defined the show's success but became a cultural icon of the '90s.

3. Castiel – Supernatural

When the angel Castiel, played by Misha Collins, first appeared on Supernatural, he was only meant for a few episodes. His complex morality, gripping storylines, and endearing awkwardness in human interactions endeared him to audiences. Fan enthusiasm helped secure his place as a series regular. Castiel's dynamic with brothers Sam and Dean Winchester added depth to the supernatural saga, making him a permanent fixture in its lore.

4. Jack Shephard – Lost

Unlike others on this list, Jack Shephard was originally written to die in the pilot episode of Lost. However, test audiences reacted so positively to his character that producers decided to make him one of the main characters instead. Matthew Fox's portrayal of Jack as the flawed yet earnest leader became central to the show’s intricate narrative. His struggles with leadership, redemption, and personal demons formed the emotional backbone of the series.

5. Ben Linus – Lost

Another Lost character who wasn't meant to last as long was Ben Linus, played by Michael Emerson. Initially scripted as a short-term role, Emerson’s compelling performance as the enigmatic Benjamin Linus captivated audiences and writers alike. His ability to oscillate between charming civility and menacing intensity provided the show with an antagonist that was as complex as he was enthralling. Ben Linus became a crucial component of the show’s evolving mystery.

6. Boyd Crowder – Justified

In the world of Justified, Boyd Crowder, played by Walton Goggins, was merely supposed to be a guest character set to die in the pilot. Yet, his chemistry with the show's lead, Raylan Givens, and an electrifying performance transformed his fate. Goggins brought such depth and charisma to Boyd's morally ambiguous outlaw that he became an integral part of the series' success. His presence sharpened the narrative and became the perfect foil to Raylan.

7. Jess Mariano – Gilmore Girls

Fresh on the scene in the second season of Gilmore Girls, Jess Mariano, played by Milo Ventimiglia, was not initially intended to be more than a rebellious detractor to Rory's otherwise stable life. Yet, Jess's intellectual prowess and raw charisma struck a chord with audiences. He evolved from the bad boy with a troubled past to a thoughtful character seeking redemption. This depth sparked interest and ultimately kept him in Stars Hollow longer than expected.

8. Fonzie – Happy Days

Fonzie, the leather-jacketed greaser played by Henry Winkler, embodies the concept of a character stealing the show. Originally intended as a secondary character, Fonzie's cool demeanor and catchy phrases quickly made him the heartthrob of Happy Days. As his popularity soared, producers shifted focus, elevating him to co-lead status. Winkler’s portrayal turned Fonzie into a beloved cultural figure of the era, driving the show’s continued success.

9. Andy Dwyer – Parks and Recreation

Chris Pratt’s Andy Dwyer started as a minor character in Parks and Recreation. Initially part of a subplot, his lovable dimwittedness and unassuming charm won fans over almost overnight. Pratt's comedic timing and improvisational skills played a large role in Andy’s increased screen time and character development. He became a cornerstone of the Parks and Rec team, contributing significantly to the show's enduring appeal.

10. Eleven – Stranger Things

Millie Bobby Brown's portrayal of Eleven in Stranger Things was so magnetic that she was pulled from a predicted short arc into the heart of the series. Her character's emotive silence, telekinetic powers, and quest for identity resonated deeply with audiences. Eleven’s journey from an enigmatic lab experiment to a heroic figure helped solidify Stranger Things as a pop-culture phenomenon and ensured her a permanent place in the story.

11. Daryl Dixon – The Walking Dead

Daryl Dixon, played by Norman Reedus, isn't found in The Walking Dead comic books but was added into the television series as an original character meant to last for a brief stint. However, Daryl's gruff demeanor, hidden loyalty, and survival skills struck a chord, making him a fan-favorite. Reedus’s portrayal was so compelling that Daryl quickly became a mainstay on the show, with audiences eager to see how his character would evolve.
