Matthew Harold Davis, more commonly referred to as Matt, was a civilian who resided on New Jerusalem and then Earth, after the First Battle of New Jerusalem. He led a fairly normal life, until he was forcibly evacuated from his home planet by Task Force Bravo. From there, he returned to his normal life, albeit on Earth rather than New Jerusalem. However, his life was ruined again, when the Covenant invaded. Luckily, he met Task Force Bravo again, and was permitted to remain with them until they escaped the city.
