Ada Wong is a character in CAPCOM's horror-adventure game series, "Resident Evil." She's an enigmatic Asian woman with an unclear background. Despite her collaboration with the major antagonist, Wesker, their relationship is one of mutual exploitation, and even her name "Ada" is merely an alias. Ada Wong's name was first mentioned in "Resident Evil 1," but she officially debuted in "Resident Evil 2." She was sent by Wesker to infiltrate the Umbrella Corporation headquarters to search for the G-virus and crossed paths with the protagonist of the second installment, Leon Scott Kennedy, forming an alliance along the way.

Among numerous Resident Evil players, especially male gamers, she enjoys an immensely high level of popularity. Not only is she considered Leon's romantic interest, but she's also dubbed the intriguing "Auntie Wong" by many players, possessing a unique allure. Despite appearing in multiple Resident Evil works and a CG movie, Ada Wong remains one of the series' most mysterious characters, with scant background information provided in the games. Nearly 30 years have passed since the release of "Resident Evil 1," yet Ada Wong seems to have remained unchanged in appearance and skill, maintaining her status as a goddess-like figure in players' minds. Her age remains a puzzle, but deducing from Leon's official birth year of 1977 and in-game documents indicating Ada is roughly four years older, she would be around 49 years old now.
