Gareth is the leader at Terminus, where he lives with his mother Mary and his crew of Terminans. He initially created Terminus as a sanctuary for survivors of the apocalypse. However, after Terminus was attacked by a gang of violent men who murdered and raped members of his group, Gareth turned Terminus into a deadly trap and eventually resorted to cannibalism. Gareth imprisons Rick’s group in a train car as he prepares to slaughter and eat them. However, Carol creates a diversion that allows Rick’s group to destroy Terminus and escape. Gareth and several other Terminans survive and follow Rick’s group to a church, where they kidnap Bob and devour his leg. Later, Gareth leads an assault on the church, but Rick’s group is able to ambush them and Gareth dies along with the rest of the Terminans in a brutal massacre.
