Billy Coen

Billy Coen is the deuteragonist of "Resident Evil Zero".

He was a U.S. Marine Corps Second Lieutenant-turned death-row inmate that escaped into the Arklay Mountains after the military transport vehicle escorting him was forced off the road by a pack of Cerberus. He took refuge in the nearby Ecliptic Express where he would later meet Rebecca Chambers, who had arrived with S.T.A.R.S. to investigate reports of murders in the vicinity.

He is voiced by David Webster in "Resident Evil Zero" and by Steve van Wormer in "Resident Evil The Umbrella Chronicles".
