1. Mickey Mouse: A Backup Plan Turned Global Icon
Before Mickey, there was Oswald the Lucky Rabbit—until Universal Studios took him from Walt Disney. In a rush to create a replacement, Disney and animator Ub Iwerks developed Mortimer Mouse, later renamed Mickey at the suggestion of Disney’s wife.
Key Facts:

Before Bugs Bunny, Warner Bros. introduced Happy Rabbit, a bland character that quickly flopped. Animator Tex Avery reshaped the concept with the sarcastic charm of Groucho Marx and a distinct Brooklyn accent.
What Changed:
-
The phrase “What’s up, Doc?” was an improvised joke by voice actor Mel Blanc.
-
Bugs starred in controversial WWII propaganda cartoons, some now deemed offensive.

3. SpongeBob SquarePants: A Cartoon with Scientific Roots
Stephen Hillenburg was a marine biology teacher before creating SpongeBob SquarePants. The character originated from an educational comic called The Intertidal Zone.

Early versions of the show had a darker, more adult tone.
Tip: SpongeBob is one of the most profitable cartoon characters in animation history.
4. Scooby-Doo: Created in Response to TV Violence Concerns
In the late 1960s, backlash against violent Saturday morning cartoons prompted Hanna-Barbera to create a mystery series focused on humor and light scares.
Behind the Scenes:

Scooby’s original name was “Too Much.”
-
His voice, including “Ruh-roh,” was improvised by Don Messick.
-
Shaggy’s look and personality were modeled after Maynard G. Krebs from The Many Loves of Dobie Gillis.

5. Homer Simpson: A Role Almost Voiced by Someone Else

Early Characterization:
-
Homer was originally much angrier and less lovable.
-
The character evolved into the bumbling, well-meaning dad fans adore.
SEO Note: Homer Simpson remains one of the most quoted cartoon characters in pop culture.
6. Pikachu: The Electric Icon That Almost Wasn’t a Mouse
Pikachu, the face of the Pokémon franchise, was originally designed more like a squirrel than a mouse.
Design Evolution:

Final look was chosen to be gender-neutral and appeal to kids.

A 1997 episode featuring flashing lights caused seizures in hundreds of children, leading to major changes in animation standards.

In 2023, Roiland was replaced after legal controversies, a rare move in animation.

Many early episodes were edited or banned due to racist content.
Legacy: Betty Boop became a feminist and pop art icon despite her rocky origins.

Cullen based his voice on his brother, a Marine.

The design shift made Optimus a symbol of strength and leadership.
