Leon S. Kennedy is depicted as around 51 years old in Resident Evil 9 (Resident Evil Requiem), based on the officially stated in‑game timeline.

How Leon’s Age Is Calculated

  • Leon is canonically 21 during the Raccoon City Incident in September 1998, as established in Resident Evil 2.
  • Resident Evil 9 (often referred to as Resident Evil Requiem) is set roughly 30 years after Raccoon City, around the year 2028.
  • Adding 30 years to his Resident Evil 2 age (21 + 30) places Leon at about 51 years old in Resident Evil 9.

Official Info vs. Fan Talk

  • Coverage of Resident Evil Requiem explicitly describes Leon as a 51‑year‑old veteran returning as a main protagonist in the farthest point of the mainline series timeline.
  • Fan discussions and social posts echo this, summarizing it simply as “Leon is 51, so it takes place in 2028.”

In-Game Timeline Context

  • The late‑2020s setting makes Resident Evil 9 the most chronologically advanced mainline entry, exploring the long‑term impact of the Raccoon City events on an older Leon.
  • This age also lines up with broader fan timeline calculations that place Leon in his late 40s by the mid‑2020s and early 50s by the time of Requiem.
