- Mortal Kombat: "Like Sub-Zero, Scorpion's true name and origin are not known. He has shown from time to time distrust and hatred towards Sub-Zero. Between Ninjas, this is usually a sign of opposing clans."
- Mortal Kombat II: "The hell-spawned spectre rises from the pits. After learning of Sub-Zero's return, he again stalks the ninja assassin- following him into the dark realm of the Outworld where he continues his own unholy mission."
- Ultimate Mortal Kombat 3: "When Shao Kahn makes a failed attempt at stealing the souls which occupy Earth's hell, Scorpion is able to escape from the Nether region. Free to roam the Earth once more, Scorpion holds allegiance with no one. He's a wild card in Earth's struggle against the Outworld."
- Mortal Kombat 4: "In hopes of gaining Scorpion as a new ally in the war with the Elder Gods, Quan Chi makes the dead Ninja an offer he cannot refuse... Life, in exchange for his services as a warrior against the Elders. Scorpion accepts, but hides under ulterior motives."
- Deadly Alliance: "The ninja spectre Scorpion had assumed for many years that Sub-Zero had killed his family and clan, only to later discover that the true murderer was the sorcerer Quan Chi. After revealing his treachery, Quan Chi then attempted to send Scorpion to the 5th plane of the Netherrealm. Thinking quickly, Scorpion grappled the sorcerer at the last moment and they were both transported to that forbidden realm. This turn of events boded well for Scorpion and his strength increased the longed he remained there. Quan Chi's powers, however, proved to be useless against him. Scorpion hunted Quan Chi relentlessly throughout the Netherrealm, thrashing him every chance he could. Eventually, Quan Chi enlisted the help of two Oni to protect him from the onslaught. When Quan Chi finally discovered a way out of the Netherrealm through a strange portal, Scorpion rushed to follow him. He emerged in Outworld but in a different location, far from his prey. He can still sense Quan Chi's presence and will hunt him wherever he runs to. There is nowhere the sorcerer can hide."
- Deception: (Bio Kard) "In his haste to confront his nemesis, Quan Chi, he was ambushed by two Oni and cast into a powerful soulnado. He would surely have been torn apart by the souls trapped there had he not managed to escape into the Void."
- Deception: "In my haste to confront my nemesis, Quan Chi, I was ambushed by two oni and cast into a powerful soulnado. I would surely have been torn apart by the souls trapped there had I not managed to escape in the Voids. It was there that I first set eyes on the fabled Elder Gods. I would forever changed by this encounter. While in the Void, I witness, along with the Elder Gods, the death of Raiden and the re-emergence of the Dragon King. Suddenly aware of my presence, the Elder Gods transformed me into their servant and gave me a new purpose: to prevent the Dragon King from merging the realms."
- Shaolin Monks: "A tormented spectre bent on revenge, Scorpion has one desire: to slay the one who killed his family and clan. Returning from the abyss of death, he will find his nemesis. He will destroy Sub-Zero."
- MK vs DCU: "Scorpion was once a member of the Shirai Ryu ninja clan before he was slain by the elder Sub-Zero. Resurrected by the sorcerer Quan Chi, he entered the Mortal Kombat tournament and killed Sub-Zero to avenge the murders of his family and clan. But Sub-Zero's younger brother assumed his name and donned the familiar blue assassin's garb. Though he remains Quan Chi's enforcer, Scorpion will not rest until this Sub-Zero has been slain as well."
Born to the Shirai Ryu Ninja clan, Hanzo Hasashi was among the best shinobi in the clan. He earned the name "Sasori" (the Japanese word for "Scorpion") because of his incredible Ninja skills, and his life was blessed with kombat for the glory of his clan's Grand Master. However, when he received a mission from the vile necromancer Quan Chi to steal the sacred Map of Elements from the Order of Light's Shaolin Temple, Scorpion was brutally murdered in battle by the Lin Kuei warrior, Sub-Zero. Consequently his family, and his clan, were slaughtered by Quan Chi as payment to the Lin Kuei. Scorpion's soul was sent to the Netherrealm, where he laid waste. He fought Sub-Zero again in the Prison of Souls during his damnation, but was defeated again, allowing the Lin Kuei warrior to escape.
Two years after being slain by the elder Sub-Zero, Scorpion returned to Earthrealm, and participated in Shang Tsung's tournament. If he defeated Sub-Zero, he would avenge himself and from what Quan Chi told him, his clan, but if he was defeated again, his soul would be hurled into oblivion. However, it would not be until after Liu Kang's defeat of Goro that he would catch Sub-Zero unguarded and have his revenge, finally killing the Lin Kuei warrior. Immediately afterwards, he returned to the Netherrealm.
While in the Netherrealm, Scorpion would catch wind of a new tournament in Outworld, as well as Sub-Zero's participation. Shocked and angered that his murderer somehow returned to life, Scorpion followed his opponent to Shao Kahn's tournament. However, during one of Sub-Zero's battles, he witnessed the Lin Kuei sparing his opponent's life. He would soon learn that this Sub-Zero was not his murderer, but Sub-Zero's younger brother. To atone for slaying his kin, Scorpion vowed to protect Sub-Zero instead. But Sub-Zero would never know this, or the reason behind it.
When Shao Kahn invaded Earthrealm and unsuccessfully tried to conquer the Netherrealm as well, Scorpion was inadvertently set free, and began walking the Earth once more. He pledged allegiance to no one, taking neither friends nor enemies. Shao Kahn, however, recognized Scorpion's superior warrior skills, and enlisted the ninja in his forces. Scorpion's allegiance with Shao Kahn quickly dissolved when he discovered that Sub-Zero was one of Earth's Chosen warriors and therefore one of Shao Kahn's targets. He turned on Shao Kahn, and sided with the Earthrealm warriors in their final showdown with the evil emperor. With Shao Kahn and his minions defeated, Earth reverted back to normal, causing Scorpion to return to the Netherrealm once more.
Sometime after his return to the Netherrealm, Scorpion heard that his wife and child had been slain. He encountered the sorcerer Quan Chi, who told Scorpion that Sub-Zero was the murderer. Hearing this angered Scorpion anew, and he swore he would slay Sub-Zero, much like his brother before him. However, in Scorpion's ending, Quan Chi reveals that he had tricked Scorpion into believing that Sub-Zero had slain his wife and child in the hope that he would break his vow of protecting Sub-Zero as retribution for killing his brother the original Sub-Zero. The true murderer of Scorpion's family was Quan Chi. After Scorpion defeated the new Sub-Zero and learned the truth, the sorcerer attempted to transport Scorpion back to the Netherrealm. Thinking quickly, the spectre ran towards the sorcerer, sending both of them back to the Netherrealm.
During the years that Quan Chi spent trapped in the fifth plane of the Netherrealm, he would be chased, brutalized, and tortured by Scorpion. Quan Chi had little chance of escape, as his powers were weakened while he was in the Netherrealm, and Scorpion's power and strength conversely increased (note: Quan Chi, as Shinnok's second-in-command, had previously resided in the Netherrealm. However, this was explained as a new region of the Netherrealm where sorcerers retain their power). Quan Chi eventually struck a deal with the two Oni, Drahmin and Moloch, who fought off Scorpion for him. When Quan Chi escaped the Netherrealm through a portal, Scorpion followed him, but it did not send him to the same place. He continued to hound Quan Chi in a game of cat-and-mouse until he found himself at Shang Tsung's palace, where he was ambushed by Drahmin and Moloch, who had also escaped the Netherrealm. They threw him into the Soulnado, believing that it would eliminate the ninja spectre once and for all.
Scorpion, however, managed to escape into the Void before the purity of the Soulnado tore him apart. While in the Void, he met the Elder Gods, and forever became changed from what he saw. He also witnessed Raiden's sacrifice and Onaga's dominance beginning to unfold. The Elder Gods were aware of his presence and enhanced his mortal and supernatural abilities, making him the Champion of the Elder Gods. The Elder Gods gave him a new mission, to seek and destroy Onaga before he unmade the realms. Scorpion emerged from the Void and returned to Outworld. Scorpion is seen in Konquest mode before Onaga goes to retrieve the amulet from Quan Chi and fights Shujinko in the name of the Elder Gods. Shujinko won the battle. In his ending it is said that Scorpion tracked Onaga through the realms to fight him, but it is actually unknown if he fought him, as it is known that Shujinko was the one who defeated the Dragon King.
In Konquest mode, Scorpion was no longer willing to serve as the Elder Gods' champion. This was due to the bargain he had made with the Elder Gods to serve them in the first place; they would resurrect the Shirai Ryu clan along with the resurrection of his wife and son, in return for his services. While the Elder Gods did fulfill their promise, they brought back the Shirai Ryu clan as hellspawned warriors, the same as Scorpion. Enraged at what he perceived as their betrayal, Scorpion vowed to gain vengeance on the Elder Gods by removing the two things crucial to their plans to prevent Armageddon - the Edenian brothers Taven and Daegon.
In the battle between the Forces of Light and the Forces of Darkness in Edenia, Scorpion is seen fighting on the Forces of Darkness and battling Sub-Zero. He was one of the final kombatants to get near to the top of the pyramid, along with Shinnok. however, in the end he was killed along with the many others - his back pierced by Sub-Zero's Kori Blade.
Scorpion first appears in Liu Kang's chapter attempting to ambush Sub-Zero but the Shaolin Monk saves Sub-Zero's life by shoving him out of the path of Scorpion's kunai and deflecting it, allowing the cryomancer to escape. Enraged that his quarry had escaped again, Scorpion challenged Liu Kang to a fight but lost. As the spectre reeled in pain, he was suddenly consumed by a yellow aura and vanished, leaving the Flash in his place in the Mortal Kombat universe.
Scorpion reappeared in the Batcave in the DC universe, right before the Dark Knight himself. Confused, Scorpion believed Batman to be Sub-Zero in disguise and challenged him, but in his weakened condition he was defeated and captured for study. Batman then brought the unconscious Scorpion along in his investigation in Gotham but the spectre awoke and escaped in the confusion of the Joker and Liu Kang's arrival.
He would reunite with Quan Chi in the Netherrealm and pull his arch-nemesis into the realm with his kunai, dragging Sub-Zero through a portal. Scorpion challenged Sub-Zero to a fight, believing him to have been his family's murderer, with Quan Chi goading him on. As Scorpion and Sub-Zero fought, the merging spread into the Netherrealm itself, allowing Quan Chi to free himself. He sent Sub-Zero back to Raiden and then ordered Scorpion to find princess Kitana, who had seen the face of their new enemy.
Scorpion returned to Gotham where he was confronted by the Joker, but he lacked the patience to deal with the clown prince of crime's antics and began to walk away, though he became enraged when he was struck from behind by him and fought him, easily defeating the Joker. Scorpion spared his life out of disgust and teleported to Themyscira, where he encountered Wonder Woman. He told her of his mission to find the princess but when Diana thought he was referring to her and offered her help, he refuted her claims and rebuffed her offer before challenging and defeating her in battle.
Scorpion next traveled to Metropolis where he met with Superman himself. Much like with Wonder Woman, he refused the Man of Steel's offer for help and gave him a hellfire covered kick for his troubles, shocking Superman when he discovered the source of Scorpion's powers were sorcery. Scorpion defeated Superman, punching him away into a nearby car and finally encountered a Kombat Rage infected Kitana, who believed he was an assassin sent by Dark Kahn. Scorpion defeated Kitana and managed to get her in a submission hold, calling out to Quan Chi.
The necromancer appeared with Baraka and Shang Tsung by his side and used his magic to place Kitana under his control. Quan Chi then spotted Captain Marvel approaching and ordered the three to deal with him in the Netherrealm while he went to Raiden. The three sprang their trap, with Scorpion using his kunai to yank Captain Marvel into the Netherrealm and was the first one to face the Earth's Mightiest Mortal, only to be defeated, his allies swiftly falling as well. They followed after Quan Chi and Scorpion witnessed the necromancer use the last of his magic to restore Kitana to sanity, pleading with Raiden to work with them to save the world.
Raiden agreed and so both Forces of Light and Darkness united, with Scorpion and Sub-Zero teaming up to face Lex Luthor and Catwoman in the Wu Shi Academy grounds, though Luthor defeated both of them while under the Kombat Rage's influence. Scorpion would then join up with the united Forces of Light and Darkness on their journey to the merged Apokolips/Outworld and due to Dark Kahn's influence, he came under the effects of the Rage and faced the Flash in the final battle with the DC Universe.
Scorpion was knocked out as a result, but he revived in time to witness the realms be restored after Dark Kahn's destruction.

- Scorpion: By defeating you, Sub-Zero, I have avenged the death of my family and clan. Now my soul can finally rest.
- Sub-Zero: Your soul will never rest, Scorpion. The Lin Kuei may have been responsible for your murder... But your family's true killer still remains free...
- Scorpion: If you are not the murderer, then who is?

- Deadly Alliance: "The hunt for Quan Chi had led Scorpion to the palace of Shang Tsung. Scorpion entered the palace through a hidden passage. As he made his way through the lower levels, he was discovered by the two Oni he had previously encountered while in the Netherrealm. Shang Tsung had secretly allied with Moloch and Drahmin as a backup defense against Quan Chi. The two Oni had been hidden in an underground chamber and were periodically fed mortals to keep them satisfied. Scorpion fought well but was overpowered by Moloch and Drahmin. Although they could not consume the ninja spectre, they devised another means for eliminating their foe that would satisfy their cruel nature. The Oni brough Scorpion before the portal to The Heavens that Shang Tsung had tapped as a source of limitless souls. They hurled him into the Soulnado and his hellspawn body was ripped apart by the purity of that realm."

The sorcerer Quan Chi suddenly appeared among them. He grabbed Scorpion's young son and disappeared through a portal to the Netherrealm. Enraged, Scorpion ordered his clan to hunt down the sorcerer. He will not rest until his son has been recovered and Quan Chi is dead!"
- MK vs. DC: "Though Dark Kahn was defeated, his consciousness lived on. The Dark Lord's power and maliciousness found the perfect host in the body of the wrathful Scorpion.
