The Return of Shinnok
TOASTY

TOASTY
It was during the time of the Dragon King's conquest of the realm, The Prophecy predicted by Delia was fulfilled. However, as Caro mistook the loss of Blaze's contact (possibly when he was kidnapped in order to watch over the Dragon King's eggs) as the signal to begin the race, Daegon had mistakenly been awakened centuries early.

He discovered what the aim of the quest was, and became obsessed with the power which would be granted to him. Daegon set up the Red Dragon clan (to represent the Red Dragon that awoke him) and enslaved Caro in order to use him to create portals.

The Red Dragon's primary aim was to find Blaze and to assassinate Taven set by his brother Daegon in order to claim the prize for himself, although they were also a powerful crime organization. When Taven was finally awoken at the correct time, during Onaga's return, he was constantly ambushed by Red Dragon warriors. Eventually, Taven made his way to his father's temple, only to find the weapon that was meant to be there had been stolen. As he finally made his way to his mother's temple, which was now occupied by the Lin Kuei, he managed to find the suit of armour that had been placed for him. During this time, Quan Chi assembled the other Evil warlords, including Shao Kahn, Shinnok, Onaga and Shang Tsung. Quan Chi had managed to find out about the power that Blaze contained, and the power that would be passed as a gift to the one who defeated him. In the process of discovering this, Quan Chi killed Orin, Taven's protector Dragon. The Forces of Darkness united in order to claim this power, whilst the Forces of Light united in order to either stop evil, or claim the power for themselves for their own ends, thus culminated in The Battle of Armageddon.

Just as Delia had predicted, at the crater within the Edenian ruins, The defining prophesized conflict came to a head. As Taven made his way to these ruins, he encountered Blaze who revealed the true nature of this quest: to either use the power to destroy all of the Mortal Kombat warriors, or simply strip them of their power. Daegon not only revealed that it was he who had killed their parents over the prize, with the very weapons their father Argus created to be used to fight against Blaze (as it became apparent that Daegon was the one who had stolen Taven's sword), he also told Taven that Shinnok warned him that their parents made the decision to assist Taven and not Daegon, in which he was envious of. As the Sons of Argus fought within the ruins with tremendous ferocity, Taven was victorious at a huge terrible cost. As this happened, the warriors clashing within the crater were suddenly stopped as the huge pyramid placed by Argus millennia earlier rose from the ground, with Blaze, now empowered and huge in size, waiting at the top. The warriors began to make their way to the top, fighting amongst themselves and turning on one another in order to claim the prize for themselves. With Daegon defeated, Taven took his sword and made his way into the crater himself, in order to defeat Blaze. However in the end, It was not Taven who defeated Blaze as he was destined in order to prevent Armageddon to the shock of all the kombatants themselves, It was Shao Kahn.

Return to the Past
After The Battle of Armageddon ended (while the Kombatants from both sides are dead), left Raiden and Shao Kahn, the only two survivors. Defeated and about to be dealt the final blow, Raiden used his last attempt to cast a spell on his amulet, now shattered, to contact his past self and quote "He Must Win!" before he was killed.

In the events of the first tournament, the Raiden from that era appears with Liu Kang in the Mortal Kombat tounament hosted by Shang Tsung, now possessing visions of the events from his future self when his amulet cracked. After the first two rounds of the tournament, with Johnny Cage defeating both Reptile and Baraka, Raiden and Liu Kang met with Cage and explained to him the reason and purpose of Mortal Kombat, which he does not believe. Cage then finds Sonya Blade (whom Cage had flirted with earlier) while she was contacting the Special Forces, and he offers to help her out. Initially hostile, Sonya warms up to Cage after he saves her from the Black Dragon mercenary, Kano, during which time Cage begins to understand the truth in Raiden's words. Later, Sonya rescues Jax with assistance from Raiden. The Thunder God then explains to the four Earthrealm warriors his visions and what they foretell.

Later, Raiden receives more future visions whereby he sees the ninja spectre Scorpion killing Sub-Zero and a new warrior forming (now known as Noob Saibot). Raiden confronts Scorpion and requests he spare Sub-Zero's life, offering to ask the Elder Gods to restore his clan, the Shirai Ryu, back to the mortal realm. this causes Scorpion to accept the request. In Shang Tsung's Throne room, Scorpion later confronts Sub-Zero, (after fighting Sektor and Cyrax), battled him in The Netherrealm and there defeated Sub-Zero. Scorpion then honors Raiden's request not to kill him, until Quan Chi appears and shows Scorpion visions of Lin Kuei forces attacking the Shirai Ryu clan and Sub-Zero killing his wife and child. This enraged Scorpion, causing him to ignore his deal with Raiden, and killing Sub-Zero. He returns to the Throne Room in regret holding the burned skull of Sub-Zero and disappears enraged. Cyrax is later contracted by Shang Tsung to kill Johnny Cage, but is rebuffed by Raiden for doing so. Cyrax defeats Cage in their match, but honors Raiden's wish and lets him live. Cyrax is confronted by Sektor regarding the interaction, but defeats him in a brawl.

Meanwhile, Kitana attempts to kill Liu Kang, but is defeated and spared. Later, Kang then defeats Ermac, Goro and Shang Tsung in the tournament. However, despite their short-lived victory, Raiden's amulet cracks further. Disappointed with Outworld's defeat, Shao Kahn orders Shang Tsung's execution, but relents after being given the proposal of holding a second tournament in Outworld. During the events of the tournament, Kitana learns of her true past, while Jax, Cage, and Raiden attempt to rescue Sonya. Along the way, Sub-Zero's younger brother and Smoke infiltrate Outworld to learn of the original Sub-Zero's fate, while Ermac maims Jax. However, due to Raiden's assistance of Smoke, Sub-Zero instead undergoes cybernetic transformation, inadvertently altering the timeline. Raiden attempts to substitute Kung Lao as the champion of the next tournament, only for Lao to be killed by Kahn after defeating Kintaro, leaving Kang to be the champion of Mortal Kombat two times in a row.

Despite Kang's seemingly fatal victory over Kahn, the latter launches an invasion of Earth. Among the response teams would be riot cops Kabal and Kurtis Stryker. Stryker and Kabal manage to defeat Kintaro, Mileena, and Reptile, but Kabal suffers severe burns from Kintaro. Meanwhile, After defeating Ermac(Unbeknownst to Stryker that Kabal disappeared), he was recruited by Nightwolf to aid Raiden in defending Earth. However, It was revealed that Kabal has been recovered by Kano only to escape from Outworld. After defeating Sub-Zero (now a cyborg), fending off Sheeva, and assisting Smoke in helping him, both join Raiden's defenders, composed of Liu Kang, Sonya Blade, Johnny Cage, Kitana, Cyber Sub-Zero (his humanity having been restored), Jax (now with cybernetic arms), Jade, Smoke, Nightwolf and Stryker. Sub-Zero confronts Sektor and retrieves intelligence from his databanks.

Sub-Zero learns that Quan Chi was sacrificing Earthrealm's souls to merge Outworld with Earthrealm, and confronts his older brother (now Noob Saibot), allowing Nightwolf to halt Quan Chi's ritual. However, the interference causes Shao Kahn's forces to assault the headquarters of the Earthrealm warriors, where everyone (except for Johnny Cage, Sonya Blade, Raiden, and Liu Kang surviving the ambush), are killed by Sindel, with Nightwolf sacrificing himself to kill the empress.

During these events, Raiden travels to the Netherealm to try to convince Quan Chi to join him against Shao Kahn, offering the souls of all the fallen Earthrealm warriors in exchange for his help. However Quan Chi reveals that he already has these souls as part of Shao Kahn's agreement with him. Quan Chi then summons these souls and pits them against Raiden. Raiden successfully defeats six of the reanimated souls when Quan Chi remarks at how Shao Khan has already won, on hearing this statement Raiden realizes that Shao Kahn has to win because by conceding to Shao Khan the Elder Gods would intervene and punish Shao Kahn for merging realms without having won 10 consecutive Mortal Kombat tournaments. Raiden returns to Earthrealm and explains his plan to Liu Kang, however Kang, dilusional with grief does not trust Raiden and goes to face Shao Kahn. Raiden, knowing that if Kang wins Armageddon will ensue, attempts to stop Kang, fighting and defeating Kang. However Kang refuses to back down from his goal. Raiden inadvertedly kills Kang while trying to stop him from fighting Shao Kahn. Raiden loses to Kahn voluntarily, only for the Elder Gods to intervene and grant him tremendous power. Raiden defeats Kahn who is attacked by the Elder Gods and is taken away for punishment, and vows to rebuild Earthrealm with Sonya Blade and Johnny Cage, the last remaining Earthrealm fighters. However, Quan Chi and Shinnok decide to use the chaos to their advantage to make their plan successful in order to claim both Earthrealm and Outworld in the name of the Netherrealm for themselves.

25 Years Later: What Would Become of the Future?
This is where Mortal Kombat X begins...

A few years following Shao Kahn's defeat, Shinnok escapes the Netherrealm and launches an invasion of Earthrealm. Shinnok personally goes to Raiden's Sky Temple with the intent to poison the Jinsei, the life force of Earthrealm. Shinnok nearly imprisons Raiden and Fujin within his amulet, only for Johnny Cage to intervene and knock the amulet from his hands. Shinnok incapacitates Cage's companions, Kenshi and Sonya Blade, but Johnny manages to hold off the former Elder God and pass the amulet over to Raiden. The tables turned, Raiden imprisons Shinnok within his own amulet. At Fujin's recommendation, the two gods take the amulet to the Elder Gods, seeking their guidance.

Soon after, Johnny and Sonya travel to Quan Chi's fortress in the Netherrealm, hoping to take down the necromancer and his revenants before they can cause any more trouble. In the fight against Quan Chi, Scorpion, and the revenants of Jax and Sub-Zero (now returned to a human form), Cage is stabbed, and Quan Chi begins summoning a revenant as his soul leaves his body. Sonya manages to defeat Quan Chi, however, and Raiden is able to reverse Quan Chi's spell, saving not only Johnny Cage, but also returning Sub-Zero, Jax, and even Scorpion to life.

In the years that follow, Johnny and Sonya marry and have a daughter, Cassie, and later divorce. Scorpion reinstates his Shirai Ryu clan while mentoring Kenshi's son Takeda, and Sub-Zero becomes the new Grandmaster of the Lin Kuei after killing Sektor.

Twenty years after Shinnok's defeat, Johnny Cage assembles a team of fighters composed of Cassie, Jax's daughter Jacqui, Takeda, and Kung Lao's cousin Kung Jin. After undergoing a training exercise with Sub-Zero, they are deployed to Outworld to resolve a civil war between former empress Mileena, who has obtained Shinnok's amulet, and Outworld's current emperor Kotal Kahn, with whom Earthrealm has a peace treaty. On Earthrealm, Sonya captures Kano and forces him to reveal where Mileena is keeping the amulet. Armed with this information, Cassie's team aids Kotal in recovering Shinnok's amulet and capturing Mileena. After executing Mileena, Kotal decides to keep the amulet in Outworld's hands, and takes Cassie and her friends hostage to prevent Raiden from retaliating. Kotal's second-in-command D'Vorah, who is revealed as a double agent for Quan Chi, steals the amulet. Cassie and her team escape captivity, and inform Sonya of D'Vorah's intentions.

Jax and Kenshi, aided by Sareena, lead an assault on the Netherrealm and manage to capture a weakened Quan Chi, who is brought back to Earthrealm and held at a refugee camp. Scorpion, having learned from Sub-Zero the truth of Quan Chi's involvement in the deaths of his family and clan, infiltrates the refugee camp alongside his clan with the intent of assassinating Quan Chi, defeating Kenshi, Johnny and Sonya in the process. As Scorpion prepares to kill Quan Chi, D'Vorah arrives with the amulet. Quan Chi manages to finish a spell moments before being beheaded by Scorpion, releasing Shinnok from captivity. Weakened by the Shirai Ryu's previous attack, Johnny is taken prisoner by Shinnok and D'Vorah. With the aid of Quan Chi's revenants, Shinnok and D'Vorah assault the Sky Temple, where they subdue Raiden. Shinnok then enters the Jinsei and corrupts it, transforming himself into a powerful demon in the process.

Cassie's team pursues Shinnok, only to be intercepted by Kotal Kahn and his army. They tell him about Shinnok's return and Kotal decides to kill them, hoping to appease Shinnok and buy time to bolster Outworld's defenses. Sub-Zero and his Lin Kuei comrades appear just in time to repel the Outworld forces. At the Sky Temple, Jacqui and Takeda occupy the revenants, while Cassie and Jin enter the Jinsei chamber. There, Cassie defeats D'Vorah and Shinnok, and rescues her father. A grievously-wounded Raiden then purifies the Jinsei, stripping Shinnok of his powers and forcing the revenants to withdraw. Sonya and her soldiers arrive, and the Cage family reunites.

Some time later, the revenants Liu Kang and Kitana are revealed to have assumed leadership of the Netherrealm. Raiden, hinted to have been corrupted in the process of purifying the Jinsei, warns them they will face "fates worse than death" if they threaten Earthrealm. As a final warning, he presents them with Shinnok's severed, yet still living head.
