Nothing is known about Colton's life prior to or as the outbreak began.
Colton and Daniel stumble across Morgan and Carol shortly after Roman's death and Morgan tells them that he has their horse and asks for their help in saving Carol, who was stabbed previously by Jiro and shot in the arm and leg by Roman.
Colton helps transport Carol to the Kingdom with Daniel and Morgan until a group of zombies attack them. Just as they were getting overwhelmed, Richard and other members from the Kingdom arrive in time to dispatch the zombies and save Colton's group.
A group of Kingdommers, at least 45, were slaughtered by an .M2 Browning machine gun used by the Saviors at the chemical plant outpost. Due to the high number of soldiers killed, it is possible Colton was among the casualties or was possibly one of the few soldiers who stayed behind and guarded the Kingdom.
This list shows the victims Colton has killed:
- Numerous counts of zombies
- "Last Day on Earth" (No Lines)
- "The Well" (No Lines)
