Wiliam (Billy) James Coen

On route to the base for his execution, the military transport vehicle used to take him there was forced off the road by James Marcus, and then Cerberus attacked and mauled the MP's guarding Billy, causing him to run for his life. Billy then sought refuge in the Ecliptic Express, a stranded train, where he met Rebecca Chambers. Despite their radically different backgrounds, the two formed an alliance in order to secure their survival. The two use their talents to pass through many of the obstacles they faced, and discovered the Umbrella Corporation's secrets.

Both were monitored by James Marcus, who sent various creatures to subdue the two. Billy proved his loyalty by saving Chambers several times during the game, whilst Rebecca proved hers by saving him. Coen and Chambers eventually met Marcus. After revealing the details of his mortal demise, the Queen leech residing in his body took control and mutated into a Leech monster.

The two managed to temporarily subdue the creature, only to discover that a self-destruct protocol had been activated, caused by William Birkin. Matters became even more complicated when the leech returned. In the final battle, Chambers exposed the leech to sunlight, thus making it vulnerable to attack.

Knowing this weakness, Billy acted as bait whilst Rebecca continued to open the roof further until there was no shade left for the creature to hide in. He proceeded to deliver a final shot, which instantly destroyed the leech. In wake of the destruction, Rebecca allowed him to escape, by telling her authorities that he subsequently perished in the Arklay Mountains after their first encounter, keeping his dog-tags as proof. The two bid farewell, and Billy disappeared soon after, not seen again. However, upon returning to Raccoon City, Rebecca filed a report claiming that Billy had died during the initial attack that allowed him to escape, she went on to request a suspension of the case which presumably allowed Billy a chance at freedom.
