20. Bart Simpson (The Simpsons)
Creator: Matt Groening
Voice: Nancy Cartwright
Every principal’s nightmare, this merry prankster’s only two real talents are skateboarding and troublemaking.
19. Daffy Duck (Looney Tunes)
Creators: Tex Avery, Bob Clampett
Voice: Mel Blanc
Daffy can himself be despicable, but he’s endearing all the same.
18. Stewie Griffin (Family Guy)
Creator: Seth MacFarlane
Voice: Seth MacFarlane
Other evil geniuses aren’t hampered by their youth, but one-year-old baby Stewie doesn’t let that stop him.
17. Ren & Stimpy
Creator: John Kricfalusi
Voice: John Kricfalusi & Billy West
Ren Hoek and Stimpson J. “Stimpy” Cat pushed the boundaries of ridiculous cartoon violence in ways that two decades later seem quaint.
16a. Phineas Flynn (Phineas and Ferb)
Creators: Dan Povenmire, Jeff “Swampy” Marsh
Voice: Vincent Martella
“Hey Ferb, I know what we’re going to do today,” Phineas says each show before launching into his latest ambitious plan to pass the summer days, whether it’s building a giant tree house that transforms into a giant robot or filming a movie or creating a time machine. And even though the stepbrothers’ grand plans escape the attention of their parents and drive Candace nuts, Phineas remains completely guileless. Hard to believe this is on the Disney Channel.
16b. Mighty Mouse
Creator: Izzy Klein
Voice: Roy Halee Sr.
He’ll swallow your bullets and spit them right back at you. He’s like a rodent Chuck Norris.
