Scorpion was originally known as Hanzo Hasashi, the greatest warrior in the Shirai Ryu ninja clan, though he was already called Scorpion by his clansmen out of respect for his assassination skills. He became a ninja to provide a better life for his wife and son against the wishes of his father, himself already a member of the Shirai. His clan's most hated rivals were the Lin Kuei clan. Scorpion and his mortal enemy Sub-Zero were both hired by Quan Chi to retrieve a scroll from the Himalayas, but the two ninjas crossed paths, leading them to fight in the mountains. Sub-Zero emerged the winner, decapitating Scorpion with his ice blade in the process. This scenario played out in Mortal Kombat Mythologies: Sub-Zero in which Scorpion played a boss. Scorpion soon found himself in the Netherrealm, where he again fought and lost to Sub-Zero later in the same game, presented with a choice: an eternity in hell, or a return to Earth as a spectre with no memories of his past. Scorpion chose revenge, and returned to Earth only to find that Sub-Zero had wiped out the Shirai Ryu clan entirely, including his wife and child.
He enrolled in the first Mortal Kombat tournament as an undead warrior to seek out and kill Sub-Zero at long last. He succeeded in this, but lost the overall tournament. His victory was short-lived when he heard that Sub-Zero had entered the second Mortal Kombat tournament and Scorpion followed suit. The wraith tracked down his nemesis but, after seeing him spare the life of an opponent, realized he couldn't be the man who killed him. It was revealed to him that this was actually Sub-Zero's younger brother, taking on his dead brother's identity to restore honor to the title of Sub-Zero in murdering so many unjustly as well as failing to kill Shang Tsung, the first tournament's host. Scorpion unexpectedly vowed to protect the new Sub-Zero, after recognizing a kinship as he had also abandoned the evil ways of his past.
In Ultimate Mortal Kombat 3, Netherrealm was invaded by Shao Kahn, who attacked Earth and recruited Scorpion into his army. The alliance, which COULD be described as deadly, was quickly dissolved when Scorpion learned of young Sub-Zero being on the side of Earth Realm. Scorpion immediately joined Earth's warriors to defeat Shao Kahn's forces but this alliance, too, was short-lived as in Mortal Kombat 4, Scorpion was tricked into believing that Sub-Zero HAD killed his family by evil sorcerer Quan Chi. Scorpion confronted and defeated Sub-Zero, who denied involvement in his family's death. Quan Chi revealed himself the true killer and cast a spell to return Scorpion to the Netherrealm. Scorpion hurled himself at Quan Chi before the spell fully took affect and transported Quan Chi to the hellish dimension with him.
Mortal Kombat: Deadly Alliance found Quan Chi rescued from Netherrealm by the demons Moloch and Drahmin, who then attacked Scorpion. Scorpion tracked Quan Chi while evading the two demons. He was unable to find the sorcerer, but was found by the Elder Gods who enlisted him to defeat Onaga before he could destroy the realms. Scorpion failed, taking the storyline to the events of Mortal Kombat: Deception, in which the realms were unmade. In Mortal Kombat: Armageddon, Scorpion entreated the Elder Gods to resurrect his clan, including his family, in exchange for serving them as an agent. Before they reunited, however, Quan Chi appeared again and dragged Scorpion's son to Netherrealm. The newly crowned leader of the revived Shirai clan vowed to not rest until he finds, and kills, Quan Chi.
Mortal Kombat 2011, as a reboot of the original story, letting Scorpion appear as an undead warrior who breathes fires just like the first game. He attends the first Mortal Kombat tournament representing Netherrealm and seeks Sub-zero's death. However, he was cured by Raiden and restored as human several years before the story of Mortal Kombat X. It was revealed that after his rebirth, he was announced by the younger Sub-zero Kuai Liang that his family was actually murdered by his former master Quan Chi. In Mortal Kombat X, Scorpion finds Quan Chi and cuts his head, fulfilling his revenge.
In Mortal Kombat 11, Scorpion together with Sub-zero defends the earth from the titan Kronika and her army, and he meets his younger self sent by Kronika from the back of the time when he was still an undead spectre. Scorpion was murdered by D’Vorah, and his sacrifice moved his younger self to join the defenders of Earthrealm.
Scorpion rarely has a grudge against any of the "boss" characters of Mortal Kombat, and as such many of his endings are actually canonical as they don't require him to win the entire tournament.
Scorpion avenges the murder of his family by killing Sub-Zero, but the victory is bittersweet for even as champion of Mortal Kombat, he can never again see them in this life.

Mortal Kombat: Deadly Alliance
Scorpion tracks Quan Chi to Shang Tsung's palace where he's confronted by Moloch and Drahmin. It seems Shang Tsung had aligned himself with the two demons in secret and kept them as a secondary defense against Quan Chi. The two demons overpower Scorpion, but are unable to consume him. Instead, they bring him to the portal to the Heavens and cast him into the Soulnado, having the souls there tear Scorpion's spectral body to shreds. Congratulations!
