Nothing is known about this survivor's life before or as the outbreak began.
This man was first part of a violent group, and after Terminus put their signs directing people to a sanctuary up this man and his group of bandits came and took over the town. For reasons that were never specified, they then killed some of the Terminus residents, with flashbacks revealing that those that were not killed were imprisoned in train carts, for reasons that also were not specified. In a flashback this man opens up the train cart, throws Mary inside then points his flashlight at the captives and selects one of the women. She is dragged out screaming and is raped by him and his men.
Later, after some point, the Termites escaped and retook the town, butchering the bandits and capturing the leader. He is imprisoned in a train car permanently as revenge and is left to rot. After Terminus starts to fall, Glenn Rhee opens up one of the train carts, letting out this man who is now insane. This crazed man runs to Rick Grimes saying, "We're the same", referencing how his bandits and the Termites are now the same type of evil. Rick, confused because he does not know the man's backstory, pushes him away and a walker bites him on the neck, killing him. He is then put down by Glenn before reanimation.
The man's motivation for murdering the Terminus residents and the significance of the strange tattoos on his face remain unknown.
This list shows the victims this man has killed:
The man was freed by Glenn from the train car, but apparently went insane from all the time spent locked inside it. He is pushed aside by Rick and is then bitten on the neck by a zombie, killing him. Directly after this, Glenn kills the walker that had bit the man and puts him down before reanimation.
