Who was the most famous cartoon character before Mickey Mouse?

That's a tricky question! It's hard to definitively say who was the *most* famous before Mickey Mouse, as fame is subjective and different characters had varying levels of popularity in different countries and eras.

However, some strong contenders for the title include:

* Felix the Cat: Created in 1919, Felix was a major star of the silent film era. His simple design and flexible body allowed for creative animation, and he was incredibly popular worldwide.

* Krazy Kat: Created in 1913, Krazy Kat was known for its quirky humor and surrealist style. It was praised by critics and became a cult favorite.

* Popeye: While Popeye first appeared in 1929, just a year before Mickey, he quickly gained immense popularity with his catchphrases and spinach-fueled strength.

* Betty Boop: Created in 1930, she became a global sensation thanks to her sassy personality and undeniable charm.

* Charlie Chaplin: While not strictly a cartoon character, Chaplin's iconic silent film persona was widely known and loved. He had a huge influence on early animation, particularly through his physical comedy.

Ultimately, the "most famous" title is a matter of debate. All of these characters were major stars in their time and contributed significantly to the development of animation.
