(Operation Raccoon City's backstory)
Leon Kennedy was a rookie police officer who was caught up with the incident in Raccoon City.
In one version of events, the USS Delta Team found Leon while awaiting extraction outside the Raccoon Police Department. USS Command, who also took notice of the survivor, refused to allow the team's evacuation until he was neutralised.
Leon escaped the group and made his way to Dr. Birkin's underground laboratory with Claire Redfield; Sherry Birkin and Ada Wong. During their exploration there, Leon stood by Ada as she seemingly died. The Delta Team arrived soon after to find both Leon and the "dead" Ada gone.
After leaving the facility, Leon; Claire and Sherry fled to Lonsdale Yard, fully aware that Umbrella's agents were hunting them. The USS team succeeded in eliminating the Army SpecOps units protecting the three, however.
