Here are some examples:
* Bugs Bunny: While Bugs' famous catchphrase "Eh, what's up, doc?" was indeed a signature Blanc vocalization, his overall speaking voice and mannerisms were closer to Blanc's natural speaking voice.
* Daffy Duck: Although he used his distinctive "duck" voice for Daffy, some of Daffy's speech patterns were quite similar to Blanc's own.
* Porky Pig: This character was a bit more exaggerated, but you can still hear hints of Blanc's natural voice in Porky's stammering.
However, it's important to note that Blanc's voice acting was highly skilled, and he transformed his natural voice into many recognizable and unique voices for his cartoon characters. He even used his natural voice for some characters like Sylvester the Cat, but with a specific vocal delivery that made it distinct from his own.
So, while Blanc did use his own voice for some characters, he was a master of vocal mimicry and developed many distinct voices that became iconic parts of animation history.
