makes contact with the other Earthrealm warriors and together they learn of Shao Kahn's scheme to invade Earth. Before and during their imprisonment meanwhile, Sonya and Kano are forced to put their differences aside and work together to survive in Outworld. She is later freed by Jax, who arrests Kano, but as soon as they pass through the portal to Earthrealm, Kano escapes and flees back to Outworld. Sonya appears as one of a few selected Earthrealm warriors whose souls were not taken following Shao Kahn's invasion of Earth in Mortal Kombat 3 (1995). She re-encounters Kano on top of a skyscraper near his fortress and after a fight, hurls him off the roof to his apparent death. In Mortal Kombat 4 (1997), after her journey into Outworld and Shao Kahn's near destruction of Earth, Sonya becomes a member of the U.S. government's Outer World Investigation Agency (OIA). However, she continues to have conflicts with the Black Dragon, especially after its last known member, Jarek, fled to Edenia while Sonya was chasing him. This leads her and Jax to team up with Liu Kang and thunder god Raiden to free the realm from the fallen Elder God Shinnok's grasp and to prevent him from coming to Earth. After Shinnok's defeat, in which Jarek had reluctantly participated in to save himself, he tries to kill Sonya, but Jax intervenes and drops him off a cliff. After returning to Earthrealm, Jax and Sonya find the cyborg Cyrax malfunctioning in a desert. The two bring him back to OIA headquarters, where they are able to restore his humanity before helping him join the agency. In Mortal Kombat: Deadly Alliance (2002), while on an assignment in the East, Sonya learns the OIA had been destroyed by an accomplice of the titular alliance of Shang Tsung and Quan Chi. Not long after, Raiden seeks out her aid against the Deadly Alliance and instructs her to meet with his other chosen warriors on Shang Tsung's abandoned island, where she develops a rivalry with Frost. To earn the right to pass into Outworld, each warrior has to defeat a representation of his or her adversary. To Sonya's surprise, hers is a stranger with a red dragon on his back. She is killed in battle against the Deadly Alliance's Tarkatan forces, but their victory is short-lived as the Dragon King Onaga reclaims Outworld and defeats them in turn.
