Which Resident Evil game first featured Ada Wong?

Resident Evil 2 first featured Ada Wong. She appears during Leon S. Kennedy’s scenario as a mysterious woman searching for her boyfriend, John, while the Raccoon City outbreak unfolds.

Ada’s role develops as Leon discovers that she is connected to the search for a G-virus sample. Her shifting loyalties and spy background became recurring elements of the series, and she later returned in Resident Evil 4, Resident Evil 6, and other related media. In Resident Evil 2, her scenes are tied specifically to Leon’s route rather than Claire Redfield’s campaign.

Ada is sometimes associated first with Resident Evil 4 because that game made her especially prominent in the Separate Ways story. However, her debut occurred in the 1998 release of Resident Evil 2. The 2019 remake retains Ada’s central connection to Leon while revising parts of her disguise, investigation, and interactions.
