Ada Wong is one of the most enigmatic and compelling characters in the Resident Evil series. First introduced in Resident Evil 2 (1998), she is a mysterious spy with unclear allegiances, operating in the shadowy world of bioterrorism and corporate espionage. Ada’s charm, intelligence, and combat skills make her a fan favorite, though her true motives often remain ambiguous.

Ada’s background is intentionally shrouded in mystery. Little is known about her early life, and much of her identity is a fabrication crafted to serve her espionage activities. She is often employed by shadowy organizations with vested interests in bioweapons, though her true loyalties remain unclear throughout the series. Her encounters with Leon S. Kennedy are a recurring and defining element of her story, blending mutual respect, romantic tension, and betrayal.
