Ada has been one of the most enigmatic characters in Resident Evil history, with her true motives still unknown
Ada Wong, a pseudonym for a mysterious Asian-American spy in the Resident Evil franchise. She has developed a reputation in the business world for being able to handle the most challenging missions and critical situations guiltlessly. She worked covertly in the background of numerous biohazard occurrences, gathering data that was helpful to several organizations while simultaneously working to sabotage them. Wong, however, has frequently deceived the organizations and clients she is linked with in order to pursue her own “real mission” and solely follows it.
Updated October 2026. We added Ada’s role in the 2023 Resident Evil 4 remake and its Separate Ways DLC, noted her absence from Resident Evil Village and Resident Evil Requiem, and corrected the FAQs about her age and film appearances.
Ada has had a very prominent role in the Resident Evil franchise, be it the games or the movies. Her mischievous and inscrutable nature has made her a fan favorite. Ada’s character has evolved greatly over the franchise’s 30-year history, while her true motive has remained an unsolved mystery. Her backstory is a huge missing piece of the Resident Evil universe. Another interesting thing about Ada Wong is that, among the numbered main games, she has appeared only in the even-numbered ones: Resident Evil 2, 4 and 6, plus the remakes of 2 and 4. She does not appear in Resident Evil Village or in Resident Evil Requiem (2026), so let’s recap the fan-favorite character’s story so far.

Resident Evil 2
Ada Wong was first mentioned in the first game of Resident Evil in a letter written by Umbrella Corporation member John, although she first appeared in the game Resident Evil 2, released in 1998. In Resident Evil 2, Ada was working as a spy for a rival company to the Umbrella Corporation and was on a mission handled by Albert Wesker to steal a sample of the G-virus. During the mission, occasionally helping Leon, Ada sneaks into the NEST laboratory and encounters Dr. Annette Birkin, Dr. William Birkin’s wife. Dr. Annette was responsible for creating the G-virus. Ada manages to obtain a tissue sample from Dr. William Birkin infected with the G-virus.
Ada also appears in the 2007 spin-off Resident Evil: The Umbrella Chronicles and is playable in Resident Evil: The Darkside Chronicles (2009). The 2019 remake of Resident Evil 2 retells her Raccoon City story and gives more time to her relationship with Leon.
Resident Evil 4
While investigating the Las Plagas parasite in Spain, Ada runs into Leon once again six years after the events of Raccoon City. Ada Wong was still working for a rival company reporting to Wesker and was on a mission to find Dr. Luis Sera in Spain. Ada saves Leon’s life several times, which shows Wesker that she does things on her own terms. Eventually, Sera was killed by Osmund Saddler and Osmund manages to take a sample of the Dominant Species Plaga with him.
Ada was captured while trying to stop Osmund Saddler, and Leon rescued her. Together they neutralized Saddler. Ada and Leon then had a standoff over the sample, and Ada managed to take it with her. Instead of giving the original Plaga sample to Wesker, she gave him a sample of the weakened Plaga, making it clear that she does not trust him.

Resident Evil 4 remake and Separate Ways (2023)
Capcom released its remake of Resident Evil 4 on March 24, 2023, with Ada voiced in English by Lily Gao. On September 21, 2023, Capcom followed it with Separate Ways, a paid DLC side story starring Ada. In it, Ada frees Luis Sera, becomes infected with a Plaga parasite herself and works on a way to suppress it while Wesker checks on her progress.
Resident Evil 6
Ada was a lead character in Resident Evil 6, unlike secondary characters in other parts of the franchise. Ada was still working in the dark, helping Leon and his partner Helena Harper to contain the global virus outbreak. Nine years after the Plaga virus outbreak in Spain, Ada was once again personally involved in a new C-virus outbreak by National Security Advisor Derek C. Simmons. Simmons had created a clone of Ada named Carla.
After being betrayed by Dr. Simmons, Carla founded Neo Umbrella and plans to spread the C-virus to some of the world’s largest cities. Throughout the game, Ada chases Carla while dodging a spiteful and irate gang of BSAA members, notably Chris Redfield, who misidentifies Ada as Carla. Ada teams up with Leon and Helena in China to eliminate Simmons after killing the mutant Carla. She found and destroyed Carla’s lab.
The story of Ada in Resident Evil 6 ends with a phone call offering another mission, which she accepts. Since then, her only new story appearance in the games has been the 2023 Resident Evil 4 remake and its Separate Ways DLC. According to PCGamesN, Ada does not appear in Resident Evil Requiem; director Koshi Nakanishi said there were no scenes in Leon and Grace’s story where her presence was needed. Fans are still waiting to learn her further story and real motive.
