- Deadly Alliance: "Sensing the cries of his captured ancestors, Kenshi agreed to help the Special Forces search for the missing agent Cyrax as a means of gaining access to that realm, which allowed him to act as both rescue party and spy. Shortly after discovering the sorcerer's whereabouts, the Agency was destroyed and with it his only means for return to Earth. Kenshi now finds himself facing The Deadly Alliance on his own. Years ago, the rogue swordsman Kenshi wandered Japan to challenge the greatest warriors. His purpose in life was simply to be the best. Shang Tsung, however, had discovered Kenshi's true heritage as a descendant of a long forgotten line of warrior kings. The sorcerer desired to consume the souls of those warrior kings and tricked the unknowing Kenshi into releasing them from their tomb, an act which left him blinded. Shang Tsung consumed the souls and left Kenshi to die in the tomb."
- Deception: "I lay near death after my fight with the Red Dragon Mavado. But the ninja Sub-Zero found me and aided my recovery. As my wounds healed, the souls of my ancestors told me of their return to my sword. Their captor, Shang Tsung, was most certainly dead -- though I did not know how or by whom. Having no more reason to remain in Outworld, I made a temporary alliance with Sub-Zero, and we began our search for a way back to Earthrealm. Still weary, I traveled with Sub-Zero to the portal that had brought him to Outworld. I noticed that his armor was charred and worn from battle. He told me of a powerful warrior named Hotaru, a loyalist to a new ruler of this realm, who had attacked him for killing a troop of Tarkatan militia. Sub-Zero thought he had killed the warrior, but I am not so sure. I have sensed a presence following us for the past few days."
- Armageddon: "With Shang Tsung rumored dead, I had no further need of the Special Forces. And although I had an ally in Sub-Zero, I had no desire to join the Lin Kuei. I returned to Earthrealm, content to be a lone warrior once again. Guided by my ancestors' sword, I hunted the wicked, slaying those who would threaten the meek. In the dark, my blindness was an advantage. I struck unseen and toppled many criminal organizations from the safety of the night. As I fought against the underworld, I intercepted encrypted communications to Mavado from a secretive clan known as the Red Dragon. The messages revealed an elaborate plan designed to ensnare one man: an Edenian half-god named Taven. The Red Dragon were in a frenzy, and it seemed as though something very important was underway. Before I could determine the location of the Red Dragon base, however, I was met by a former ally, Johnny Cage. He believed that the fallen Elder God Shinnok had resurfaced and wanted to gather the Forces of Light to discuss a battle plan. I refused the invitation, not wanting to get involved in yet another pointless melee between "good" and "evil". I had my own agenda: bring down the Red Dragon and finish Mavado. Alone in the Botan Jungle, stalking Red Dragon scouts, I was overwhelmed by an intense psychic scream. I became aware of Taven and Daegon and their quest to slay the fire elemental, Blaze. My sword also heard the scream and pleaded with me to ally with the Forces of Light once more. I had received insight from my blade before, but this time it seemed drawn to kombat. It was as if I could feel the sword pulling me towards some epic clash. I will not deny its cry for blood. Though Johnny Cage is gathering the Forces of Light, I will be the one to take them into battle. The lone warrior will become a leader of many."
A born fighter, Kenshi wandered Earthrealm in search of worthy competition. Every time he found an opponent, he would defeat him just to boost his pride, but one day, Kenshi encountered a man named Song, who convinced Kenshi that a great warrior needed a great sword. Song led Kenshi to the location of an ancient and powerful sword, and he claimed that the sword would befit Kenshi's power, but as Kenshi unsealed the well wherein the sword supposedly lay, he was overwhelmed by souls trapped within and permanently blinded. Song revealed himself to be none other than the vile sorcerer Shang Tsung and proceeded to absorb the released souls and left Kenshi to die within the tomb. However, the sword, which actually did exist, attracted Kenshi and spoke to him, leading him from the tomb and revealed to him his origin.
The sword originally belonged to a long line of great swordsmen from whom Kenshi descended; the well where the sword lay was also the sacred resting place of the souls of Kenshi's ancestors, souls that were stolen by Shang Tsung. Kenshi spent the next decade or so retraining his senses, all while searching for his betrayer and the defiler of his ancestry, a path which led him to the U.S. Special Forces.
Kenshi's special abilities eventually caught the attention of Jax Briggs and Sonya Blade who, at the time, were looking for members with special talents to join their side and venture into Outworld; Kenshi jumped at the chance to pursue the man who had deceived him. After going through many tests and examinations, he was accepted to join the Outer World Investigation Agency.
His chance at exacting his revenge came when he was assigned to find the lost Cyrax, another agent of the Special Forces, in Outworld. In his travels across Outworld, he encountered the enigmatic Ermac, and, in a moment of pity, broke the mind control that Shao Kahn had over him. In gratitude, Ermac taught Kenshi the Telekinetic Slam. Kenshi soon discovered the Deadly Alliance and their plans, but was unable to contact the OWIA (which had been bombed by Hsu Hao). Unknown to Kenshi, was the fact that the Deadly Alliance knew of his presence in Outworld and sent Mavado to kill him. Mavado confronted Kenshi, defeated the swordsman, and left him to die.
The Lin Kuei warrior Sub-Zero found the dying Kenshi and nursed him back to health. Because of Sub-Zero's sympathy and kindness, Kenshi forged a temporary alliance with Sub-Zero to find a portal that would take them back home, though this temporary alliance soon became a long-lasting friendship. After Shang Tsung's death upon Onaga's return, Kenshi sensed the souls of his ancestors return to his sword, indicating the end of his quest for vengeance. Despite being an ally of both, he relinquished his position in the Special Forces and chose to remain unaligned from Sub-Zero's Lin Kuei clan, preferring to be a lone warrior.
Kenshi then returned to Earthrealm where, under the guidance of his ancestors' sword, he would hunt down the corrupt. Attacking only during the night, using the darkness as a cover to strike unseen, Kenshi was able to overthrow several criminal organizations. He eventually intercepts a coded message sent to Mavado and learns of the Red Dragon's plans to capture the Edenian half-god Taven. Before he could find out the location of their secret base, Kenshi encounters Johnny Cage who is gathering warriors to fight for the Forces of Light against the fallen Elder God Shinnok and his forces of evil. However, Kenshi declines this offer, considering this another pointless struggle between "good" and "evil."
While embarking on his mission to destroy the Red Dragon and exact revenge on Mavado, he receives a psychic premonition, becoming fully aware of Taven and Daegon's quest to defeat the fire elemental Blaze. His sword also urges him to side with the forces of light in the forthcoming conflict. Taking heed of this insight, Kenshi decides that he will be the one to lead off the Forces of Light into battle.
During the battle of Armageddon, Kenshi killed Sheeva while climbing the Pyramid of Argus, and proceeded to fight Quan Chi, who was victorious over him. Lying on the ground defeated, Kenshi was finished by Shang Tsung, disguising himself as Ermac.
- Deadly Alliance (Non-Canonical): "Kenshi had finally caught up with Shang Tsung in Outworld. Years ago, Kenshi had been manipulated into releasing the souls of his warrior ancestors. Shang Tsung had consumed those souls and left Kenshi to die in the tomb. The ordeal left Kenshi blinded, but the sword of his ancestors led him out of the depths. To redeem himself, Kenshi had vowed to free his ancestors from their captor. He cut Shang Tsung down with his ancestral sword and a blast of souls was instantly released. The spirits of the warrior kings reentered the sword as Kenshi held it above his head. His duty fulfilled, he could now return to Earthrealm."
- Deception (Non-Canonical): "As Sub-Zero and Kenshi trekked across Outworld, they strove to keep themselves hidden, only traveling at night. But as they neared the portal to Earthrealm, the Dragon King zealot Hotaru attacked with a blast of glowing energy that temporarily blinded Sub-Zero. Kenshi's sense of sight is of a spiritual nature, thus, he was unaffected by the intense flash of Hotaru's projectile attack. In the dark, Kenshi had the advantage. Hotaru did not see his approach. Unaware, he strode in to kill Sub-Zero. It was the last mistake he would ever make."
- Armageddon (Non-Canonical): "The fire of Blaze burned away the curse responsible for Kenshi's blindness. Not only was his sight restored, but he gained increased sensitivity in his other senses as well. As time went on, however, he found the sensory bombardment unbearable. Kenshi retreated to a remote mountain cavern where he remains isolated in a darkened, soundless chamber."
