14 Iconic TV Characters That Were Only Supposed to Appear Once

Some TV characters arrive with years of story already mapped out. Others are basically hired to walk in, cause a little trouble, and disappear forever. Then an actor clicks with the material so perfectly that everyone involved has to rethink the plan. A character meant for one episode suddenly becomes a fan favorite, a series regular, or even one of the faces people remember most clearly from the entire show. Sometimes the original script literally killed them off. Sometimes the contract covered a single day of work. Either way, television history would look very different if the writers had actually stuck to the plan. Here are 15 iconic TV characters that were only supposed to appear once.

Steve Urkel Was Just the Weird Neighbor

Steve Urkel was written as a one-time guest on Family Matters. Jaleel White made such an impression that Urkel eventually became the character most associated with the entire series.

Janice Was Supposed to Be One Bad Date

Maggie Wheeler originally expected Janice to appear in a single episode of Friends. The writers loved the character enough to keep finding increasingly ridiculous ways to bring her back.

Mike Ehrmantraut Only Existed Because Bob Odenkirk Was Busy

Breaking Bad needed someone to handle a scene Saul Goodman was supposed to perform, but Bob Odenkirk was unavailable. Jonathan Banks arrived as Mike for what he thought was one day of work.

Felicity Smoak Had a Two-Scene Contract

Emily Bett Rickards was initially hired for just two scenes in one Arrow episode. Her chemistry with Stephen Amell impressed the production so much that Felicity eventually became a series regular.

NoHo Hank Was Supposed to Die Immediately

Anthony Carrigan originally signed on to play NoHo Hank for the Barry pilot, where the character was meant to be killed. Carrigan was so funny that the creators changed his fate.

Mimi Bobeck Was a One-Shot Guest

Kathy Kinney was hired for a single appearance in The Drew Carey Show pilot. Once the episode was edited, the producers realized Mimi was far too funny to lose.

Lilith Sternin Wasn’t Supposed to Stick Around

Bebe Neuwirth’s first appearance as Lilith on Cheers was intended as a one-off. She returned the following season, became a recurring favorite, and eventually joined the main cast.

Garak Was Just a Simple Tailor

Garak entered Star Trek: Deep Space Nine as a mysterious tailor in what Andrew Robinson assumed was a one-time guest role. His shady past, witty banter, and moral ambiguity quickly made him indispensable.

Elka Ostrovsky Was Only Signed for the Pilot

Betty White agreed to play Elka in the Hot in Cleveland pilot on the condition that it was a one-shot appearance. Then the show got picked up, and she became essential to it.

Colin Robinson Started as One Joke

The energy vampire on What We Do in the Shadows was initially conceived as more of a one-off joke for the pilot. Mark Proksch instead turned Colin Robinson into a core character.

Gibby Was Just a Random Guest Star

Gibby was not even part of the original iCarly concept. Once Noah Munck played him, the producers liked the character enough to keep inviting him back until he became a regular.

Chiana Was Almost Gone After One Episode

Chiana was originally expected to appear once on Farscape, with the possibility that she would not even survive the episode. Gigi Edgley impressed the producers, and Chiana became a regular instead.

Sheriff Jody Mills Was Guest of the Week

Kim Rhodes has said Jody Mills was originally just another one-episode guest on Supernatural. Instead, she returned across ten seasons and became one of the Winchesters’ closest allies.

Boyd Crowder Was Dead in the Original Pilot

Justified originally followed its source material by killing Boyd Crowder in the premiere. Test audiences responded so strongly to Walton Goggins that the character survived and became central to the series.
