Gareth

The Walking Dead
Gareth is a fictional cannibal featured on the AMC survival horror series The Walking Dead. Played by actor Andrew J. West, he first appeared in the season four finale, "A". He became the central antagonist for the first three episodes of season five. Gareth was a survivor of the zombie apocalypse and became the leader of a group operating out of Georgia. When food became scarce, Gareth and his followers turned to cannibalism. In short order, this became their chosen lifestyle. They headquartered themselves in a community called Terminus. To lure prospective meals to their home, they posted signs on all connecting roads, pointing the way towards Terminus with the promise of "Sanctuary" for all who sought it. Rick Grimes and his group became prisoners of Gareth and the others at Terminus. They escaped with the help of Carol Peletier, who arrived just in time, and killed many of the people in the community. Gareth and the few who were still alive wanted revenge against Rick's group and tracked them to a church run by a man named Gabriel Stokes. They captured a member of the group, Bob Stookey, and cut off his leg, cooked it over a fire, and ate it. Bob had the last laugh however, as he had previously been bitten by a walker and laughed when he told them that they were eating tainted meat. Bob died, and Gareth's people advanced on the church. Rick and several others fought back with Rick ultimately killing Gareth by hacking him to pieces with a machete.
