Characters
Leon S. Kennedy is a former police officer and U.S. government agent who became a leading specialist in countering biological threats. He is a brave, intelligent, and disciplined individual with a calm demeanor, often maintaining his composure in even the most desperate situations. While he possesses an ironic sense of humor, he also carries a heavy sense of responsibility and often puts the safety of others above his own. His story began on his first day as a police officer in Raccoon City, where he became trapped in the disaster that unfolded.
