- "The Coalition of Ordered Governments turned their back on me when I needed them most. I can't say that I'll ever forgive them. "
- — Larry O'Neil
O'Neil was a former Gear who was proud of being in the service. He was always found with the men he called his brethren, fighting side by side with them during the Pendulum Wars. It was not until Emergence Day that O'Neil rejected all connections to the COG and retreated back to Montevado after the loss of his family.
After the orbital bombardment of Sera, there were millions of humans left to fend for themselves. The now-dubbed "Stranded" generally view the COG and the Gears as fascist for sacrificing them to the Locust onslaught. Larry was one of these few individuals who managed to survive the entire ordeal and took refuge in Montevado with his new family and other survivors.
