Cartoon shows often change with time, and not every character makes the cut. Some were written out due to shifts in storyline, voice actor changes, or low audience interest. These 12 characters quietly disappeared from popular shows, leaving fans wondering where they went.

1. Poochie – The Simpsons

Poochie was introduced in a single episode as a hip, edgy dog character added to the Itchy & Scratchy cartoon. He was created to boost ratings but was immediately rejected by fans in the story. The writers “sent him back to his home planet” as a joke. Though fictional within the show’s universe, his removal became a famous example of how to write off a character quickly.

2. Penny – Inspector Gadget

Penny was Inspector Gadget’s smart niece who often solved the crimes behind the scenes. Over time, newer adaptations focused less on her and more on other characters or changed the show’s direction. In some reboots, she had a reduced role or was absent. Fans of the original missed her presence.

3. April – Teenage Mutant Ninja Turtles (2003 series)

April O’Neil was a core part of the 2003 TMNT series but faded from the later seasons. As storylines shifted toward space and other dimensions, her appearances became rare. The focus moved to the Turtles’ adventures without her. She returned in other versions but not with the same depth.

4. Terrence – Foster’s Home for Imaginary Friends

Dil, the baby brother from Rugrats, returned in All Grown Up! as a quirky teen. He had a big personality early on but was featured less as the show progressed. The focus shifted to other characters’ school and social lives. Dil eventually became more of a background character.

Frankie started as a central character, helping run the home and managing the chaos. As the series went on, the focus leaned more on the imaginary friends themselves. Frankie’s appearances grew fewer, and her storylines were rarely developed. She became more of a background figure.

Misty was Ash’s original travel companion and a fan favorite from the early seasons. She left the show to run her family’s gym, and though she returned for cameos, she never became a full-time character again. Later seasons focused on new companions. Her exit was one of the most talked-about among fans.

9. Ron the Death Eater – The Grim Adventures of Billy & Mandy
