8) Tyreese
Both the comic book and TV version of Tyreese are fan favourites, but that doesn’t mean they’re exactly the same character. In fact, his backstory, romantic history and general demeanour are completely different on screen.
In the comics, Tyreese turns up much earlier than in the series and grows into Rick’s number two and occasional rival for leadership. He was once in a relationship with Carol, before he cheated on her with Michonne. After his daughter committed suicide, he grew a thicker skin and a darker personality until he was executed by the Governor. A fate that was later given to Herschel on the TV show.
On TV, Tyreese has no daughter to mourn and doesn’t date Carol. With this backstory done away with, he’s a much more open, empathetic character. Though of course, he still met an emotional end. In the show, he’s bitten by a zombie and suffers a prolonged period of hallucinations of his old friends, family and enemies.
