Ada Wong[a] is a character in Resident Evil (Biohazard in Japan), a survival horror video game series created by the Japanese company Capcom. Ada was first mentioned in the original Resident Evil (1996), before being introduced as a supporting character and antiheroine in Resident Evil 2 (1998). The character was initially conceived as a researcher named Linda for the prototype of the second game, but her name was changed to Ada and she was rewritten as a spy and mercenary for the final build to connect its story to that of the original.
