Mortal Kombat: Annihilation is a 1997 American martial arts fantasy film directed by John R. Leonetti in his directorial debut. Based on the Mortal Kombat video game franchise, it is the second installment in the Mortal Kombat film series and a sequel to the original 1995 film, of which Leonetti served as cinematographer. Largely an adaptation of the video game Mortal Kombat 3 (1995), Annihilation follows Liu Kang and his allies as they attempt to stop the malevolent Shao Kahn from conquering Earthrealm. It stars Robin Shou as Liu, Talisa Soto as Kitana, James Remar as Rayden, Sandra Hess as Sonya Blade, Lynn Red Williams as Jax, and Brian Thompson as Kahn. Only Shou and Soto reprise their roles, with the rest of the characters recast from the previous film.
Released to theaters by New Line Cinema on November 21, 1997, Mortal Kombat: Annihilation was panned by critics, with criticism for its story, characters, and special effects. It was also a commercial failure, grossing $51 million against a $30 million budget. Due to the film's poor critical and commercial performance, a direct sequel was cancelled. A third Mortal Kombat film languished in development hell for nearly two decades until the series was rebooted with a 2021 installment.
The Outworld emperor Shao Kahn opens a portal to Earthrealm and has resurrected Queen Sindel, Princess Kitana's long-deceased mother, to facilitate his invasion. Thunder god Rayden and Earthrealm warriors Liu Kang, Sonya Blade, and Johnny Cage try to defend themselves, but Kahn kills Cage. The Earthrealm warriors retreat to seek allies.
Sonya Blade enlists the help of her Special Forces partner, Jax, while Kitana and Liu search for a Native American shaman named Nightwolf, who seemingly knows the key to defeating Kahn. Scorpion appears and kidnaps Kitana.
Rayden meets with the Elder Gods and asks them why Kahn was allowed to break the tournament rules and force his way into Earthrealm, and how he can be stopped. One says that reuniting Kitana with her mother, Sindel, is the key to breaking Kahn's hold on Earthrealm, but another Elder God insists that the defeat of Kahn himself is the solution. Rayden is then asked by the Elder Gods about his feelings and obligations towards the mortals, and what he would be willing to do to ensure their survival.
Liu finds Nightwolf, who teaches him about the power of the Animality, a form of shapeshifting which utilizes the caster's strengths and abilities. To achieve the mindset needed to acquire this power, Liu must pass three tests. The first is a trial of his self-esteem, courage, and focus. The second comes in the form of temptation, which manifests itself in the form of Jade, a mysterious warrior who attempts to seduce Liu and offers her assistance after he resists her advances. Liu accepts Jade's offer and takes her with him to the Elder Gods' temple, where he and his friends meet with Rayden. The third test is never revealed.
The Earthrealm warriors learn that Rayden has sacrificed his immortality to freely fight alongside them. Together, they infiltrate Outworld to rescue Kitana and reunite her with Sindel in hopes of restoring her soul and closing the Outworld portal to Earth. Liu rescues Kitana while the others incapacitate Sindel. However, Sindel remains under Kahn's control and escapes during an ambush. Jade reveals herself to be a double agent sent by Kahn to disrupt the heroes' plans. Kahn feeds Jade to a gargoyle for her failure. Rayden reveals that Shao Kahn is his brother and that the former Elder God Shinnok is their father. He realizes that Shinnok is supporting Kahn. Rayden and the Earthrealm warriors make their way to Kahn, Sindel, and his remaining generals. Shinnok demands that Rayden submit to him and restore their broken family, at the expense of his mortal friends. Rayden refuses and is killed by an energy blast from Shao Kahn.
Jax, Sonya, and Kitana emerge victorious over Kahn's generals. Liu struggles with Kahn. Liu's Animality proves effective, exposing a cut to Kahn that proves he is now mortal, as a consequence of his breaking the sacred rules. Shinnok attempts to intervene and kill Liu on Kahn's behalf, but two of the Elder Gods arrive, having uncovered Shinnok's treachery. They declare that the fate of Earth shall be decided in Mortal Kombat. Liu defeats Kahn, and Shinnok is banished to the Netherrealm. Earthrealm reverts to its former state. With Kahn's hold over Sindel broken, she reunites with Kitana. Rayden is revived by the Elder Gods, who bestow upon him his father's former position. Before departing to the immortal realm, he enjoins the Earthrealm warriors to be there for one another. The Earthrealm warriors return home.
