Cartoon Characters that get little to no love

Let me see. Brainy Smurf, Casper--think of all those who flee when they see him, Arnold, the paper boy from "The Flintstones," and Astro.

Oh, the Trix Rabbit for one. Every so often, a mail-in vote is held by General Mills on whether or not the Rabbit should get a bowl of Trix cereal. Every one of these polls resulted in an overwhelming vote to let the Rabbit have some. It works out to one bowl per eleven years of "Silly Rabbit, Trix are for kids."

Dick Dastardly, the Villain Protagonist of the Wacky Races, and later, Dastardly And Muttley In Their Flying Machines. Never once won a race, nor ever caught that messenger pigeon. He did get his squadron to re-enlist though: by tricking them into thinking they were signing Dick's journal. The pages were actually re-enlist forms cleverly folded to look like blank pages.

Alexandra Cabot, personal foil to Josie And The Pussycats. It wasn't until the 2001 live-action movie that Alexandra got thrown a bone, namely Les of boy-band Du Jour.

Amusingly enough though, Jon Arbuckle has been dating Liz the veterinarian for some time now in the comics--I think the Garfield Show even showed her dating him.
Johnny Bravo never was very lucky with the ladies--or life really.
Charlie Dog was never really able to find a master.
Buttons was almost always getting scolded for something or other by Mindy's mother despite always keeping her out of danger. (Wakko's Wish finally put a happy ending on that one)

Also, Baby Puss, the saber toothed tiger from "The Flintstones." He was only in a handful of episodes, but did nothing more than accompany the families to the drive-in, and of course, put Fred outside, and lock him out of the house.
