Melissa Ponzio | Karen
Karen was a humble teacher before she was forced to learn how to fight following the virus outbreak. She’s a close friend of Rick’s and one of the main protagonists of the series. After the Governor-led massacre, she moved to the Prison and formed a relationship with Tyreese Williams.
Her time on the show lasted a little more than two seasons. While in the Prison, she begins to exhibit symptoms of an unknown disease and is forced to isolate herself away from the healthy people. Concerned that her disease will spread to the others, Carol kills her and burns her corpse.
