Michael Rooker | Merle Dixon
From his last name, you can tell that Merle Dixon is somehow related to Daryl. It turns out that Merle is actually Daryl’s older brother, though the two couldn’t be any more different. Merle fought on the side of evil and joined the Governor to wreak havoc on the other communities.
He appeared in the first season of the series but turned into a reanimated version of himself in the third. However, before his life comes to an end, he redeems himself by not surrendering Michonne to the Governor, but his plot to ambush his former boss goes south and his own community beats him to a pulp and receives a bullet wound in the heart.
