Leon S. Kennedy was a rookie police officer assigned to the Raccoon City Police Department on his first day of duty. Delayed after a breakup, he arrived in Raccoon City just as the city was being overrun by the T-virus outbreak. Alongside Claire Redfield, he fought to survive, uncovered the truth behind the disaster, and escaped before the city was destroyed. Impressed by his abilities, the U.S. government recruited him as a federal agent, where he underwent extensive training and later became one of its top operatives, specializing in high-risk missions involving bioterrorism.
