10. T-Dog
After a promising start in Season 1 where he tripped over and dropped a key, T-Dog became what can only be described as a glorified extra. Written in to fill the racial quota that all television shows and films must meet; T-Dog did have the occasional line but mostly he was just a wallflower. So under developed, you can imagine actor IronE Singleton, turning each page of the script, ready to mark his lines and being left disappointed because he didn't even have to take the lid off his highlighter pen. But he did make it to season 3 where he teased us that he might have finally found his spark. He even voiced an opinion to Rick about whether the inmates in the prison should be allowed to interact with their group. However, his new found voice was short lived; he was killed off saving Carol. It was supposed to be heroic, but because no one cared about him (including the writers), people were more upset for the zombies he killed.
