I don't watch cartoons as much as I used too, but my one of my favorite characters is Iago from Aladdin. "Ya got a problem, Pinky?!"

[The Blue Toad]

Haha.  I gotta say, it was pretty funny when he whacked that flammingo. 
But I would say my favorite cartoon is....Pikachu... :-)
Even though I don't like Poke'mon at all anymore, and Pikachu has changed for the worse in the series, he's still an awesome little yellow...dude.....
...and The Cheat is too.....

The Loony Toons
Quickdraw McGraw (aka 'El Kabong')
Dastardly & Mutley
The Pink Panther

I really enjoy the classics.  I'm so thankful they've been preserved on Boomerang!

Now, for the list.

Ed, Edd, and Eddy (from the cartoon of the same name.):  These guys are hilarious. Especially when they mess up, which is pretty much every episode.  Plus, I love the nonsense that comes out of Ed's mouth.

Huey, Louie (spelling?) and Dewey (from Ducktales): These ducks were a great source of mischief in one of Disney's all-time greatest cartoons.

Sonic the Hedgehog: Either by game or cartoon, Sonic the Hedgehog is an icon, and one of my all-time favorites.

Mario: The man, the plumber, the legend.  Mario is the icon of videogaming, and he had three cartoons based off of the games.

Those are my top favorites.  I have a lot more, but I forgot most of them.
