who is ada wong?

Ada Wong is the pseudonym of an enigmatic unnamed spy of Asian-American descent. She has gained notoriety in the corporate world for being able to handle serious situations and the most difficult requests without guilt.

Wong has acted secretly in the background of many biohazard incidents and collected information which became useful to several organisations, while at the same time operating to undermine them. However, Wong follows only her own "true purpose" and has often betrayed the organisations and customers she is affiliated with to achieve it.

Wong's personal life is a complete mystery. Her ethnicity and nationality are left unconfirmed, and when and where she was born are also unknown, not to mention her birth date.
