Leon S. Kennedy is expected to be around his late 40s to early 50s in Resident Evil 9, often reported as roughly 48–51 years old depending on which leak or timeline assumption is used.

Basis for his age

Most timeline breakdowns place Leon at 21 in Resident Evil 2 (1998) and 27 in Resident Evil 4 (2004), then track forward through later titles and CGI movies. Using those anchor points and the in-universe dates, he is 38 in the CGI film Death Island, which then lets fans project his age into future games.

RE9 / Requiem setting

Current leaks and reports suggest Resident Evil 9 (often called Resident Evil Requiem) is set around 2026–2028. With Leon’s established birth year and prior ages, that places him in the 48–51 range by the time of RE9’s events.
