Ada Wong

is a character in the survival horror video game series Resident Evil (Biohazard in Japan), which Japanese company Capcom created. Ada was introduced as a supporting character in Resident Evil 2 (1998) and became a playable character in Resident Evil 4 (2005). She is a mysterious, ambiguous spy who works for villains but frequently rescues the series' protagonist Leon S. Kennedy from dire situations. The character was originally created as a researcher named Linda and was further developed at Hideki Kamiya's suggestion. Writer Noboru Sugimura transformed her into a spy named Ada, who works to infiltrate Umbrella Corporation and is caught up in a zombie outbreak in Raccoon City. Ada appears in several Resident Evil games, novelizations and films, and also appears in other game franchises, including Project X Zone, Teppen and Dead by Daylight. Video game publications have well-received the character for fulfilling the femme fatale archetype but she has been criticized as a product of the male gaze. Several actresses have portrayed Ada, including Li Bingbing and Lily Gao in the live-action Resident Evil films.
