#20: Tom Kenny – SpongeBob SquarePants
SpongeBob SquarePants is another iconic cartoon character that has been a fan favorite since 1999. SpongeBob is voiced by Tom Kenny and is characterized by a high-pitched, manic voice that is basically his signature and what makes a big part of this character.
The shrill, bubbly, amped-up intensity of Kenny’s voice captures the endearing essence of SpongeBob. Although some people find him annoying, SpongeBob’s maniacal energy is something you just can’t refuse. Even though this is by far his most memorable role, Kenny has also lent his voice to various characters of The Powerpuff Girls, Adventure Time, and other cartoons.
