(The Tinhangse Publishing mythos)
Ada Wong was a woman who was caught up in the incidents in Raccoon City.
Ada met Leon Kennedy in the viral outbreak, and accompanied him to Dr. Birkin's laboratory. Here, she was attacked by the mutant Dr. William, and Leon was forced to seek medicine for her back in the city.
Ada failed to escape the city in time to avoid the bombing. Moving through an underground facility, she encountered the Annihilator. The Annihilator proceeded to attack and impregnate her.
