Billy Coen
Information
Originally a 2nd Lieutenant in the U.S. Marine Corps, Billy has great powers of insight and can expertly use any weapon. Although he doesn't speak much, his sense of justice is twice as strong as anyone else's.
This man, who once worked as a lone soldier for his country, was now a “top-class assassin" waiting for the day of his execution. But how did this man, who once carried out the cruelest of missions without any reservations, fall so low as to become a prisoner awaiting death? It had all happened one year earlier.
Billy was working in Africa in order to quell a civil war, and he and several of his colleagues sneaked deep into the jungle. Their mission was to reduce the number of guerillas, who were the root cause of the civil war. However, as a result of false information, the unit found themselves lost and wandering in the deep jungle. By the time they arrived at the settlement, they had only four party members left due to illness and multiple battles.
The unit commander ordered Billy and his exhausted companions to kill everyone in the village. After they returned home emptyhanded, the unit commander was furious. The murders of 23 innocent people were pinned on Billy, who had refused to carry out his orders. A military tribunal sentenced him to death. While transferring to Lexson base, where the execution was to be carried out, Billy was saved by the biological disaster that occurred in the Arklay Mountains. He escaped into a Ecliptic Express that was stopped in the forest, and there he met Rebecca Chambers from the S.T.A.R.S. unit.
From Rebecca's point of view, Billy was nothing more than a criminal deserter in handcuffs. But when he promised to join forces with her during the crisis, he risked his very life to help her. Rebecca was suspicious of Billy at first, but after watching him play the piano and seeing his honest personality, her distrust of him gradually waned. Then, when their joint investigation of the Umbrella officer training school was finished, Billy received his freedom from Rebecca. To cover his tracks, she submitted a report of his death to HQ.
