Kano freed Jarek and other Black Dragon members from a United States Special Forces detention facility. Kano had proposed to reform the Black Dragon clan, but in reality merely wished to use them to slow down any Special Forces agents who may have followed him. Jarek was stationed as head of security at a downtown office which the clan was using as a front for their activities. While there, he was confronted by Major Jackson Briggs on the building's helipad. Jarek was soon defeated and brought back into custody.
Shortly before the events of Mortal Kombat 4, Jarek was able to escape to Edenia after learning of Kano's apparent death. Now thought to be the last surviving member of the Black Dragon, he was pursued by Sonya Blade and Jax who were seeking to destroy the last remnants of the clan forever. However, seeing that all of humanity was faced the threat of Shinnok's invasion during this period, they decided to focus their attention on the new threat, and Jarek agreed to help his sworn enemies defeat this common foe. After the destruction of Shinnok's forces, he resisted allowing himself to be turned over to the Special Forces. The encounter concluded with Jarek running off to Sonya and trying to throw Her from the cliff but Sonya managed to evade Him, with Jarek's aparent death in the process. Mortal Kombat: Armageddon reveals that he survived this brush with death by driving his weapon into the ravine side, slowing down his fall enough so that he only ended up gravely injured. Using his presumed demise as a cover, Jarek went into hiding and began to master new fatality techniques in order to exact revenge on his adversaries. However, he became frustrated with the difficulties that his injuries befell him, and soon he wished to do nothing more than to kill everyone. Quan Chi found Jarek and promised him that, in return for aiding the side of the Forces of Darkness, the sorcerer would give him the ability to enhance the strength and capabilities of his fatalities, and he would be given a chance to challenge all of his foes at once. Jarek agreed and headed into Edenia to take part in the final battle.
In Jarek's Armageddon ending, he defeats Blaze, and the chi from all the other warriors begins to flow through the firespawn and funnel into him. He starts to feel as if Death itself were guiding his actions. Sealing off the crater, Jarek begins to perform the other fighters' own signature fatalities on them, eventually finishing them all.
- Mortal Kombat 4: "Believed to be the last member of Kano's klan, the Black Dragon, , Jarek is hunted down by Special Forces agent Sonya Blade for crimes against humanity. With the emergence of a much greater evil, Sonya focuses her strength on the new menacing Quan Chi. Jarek now finds himself fighting alongside Sonya and Earth's warriors to help defeat the evil Elder God, Shinnok."
- Armageddon Bio Kard: "Long thought to be the last remaining member of the Black Dragon, Jarek had served as Kano's second-in-command. After his master's apparent death, Jarek fled to Edenia. Shinnok's attempt to take control of the realms seemed to leave him no other choice, and so Jarek joined forces with his sworn enemies, Sonya Blade and Jackson Briggs."
- Armageddon: "What was done to me by the Special Forces could only be described as brutality. But that's fine. I can take it. What angered me was that somehow Jax found me. I'd covered my trail, kept to the shadows. But still I was routed out. Jax dropped me into a ravine, assuming that would be the end of me. It would have been if I hadn't thrust my weapon into the cliff wall to slow my descent. I was badly injured, so I went into hiding. My rumored death would be the ultimate camouflage as I regained my strength. Obsessed with thoughts of revenge, I traveled all over the realms looking for ancient texts that would show me a fatality worthy of my betrayer. But my injuries made perfecting these new techniques a very painful task. My frustration turned into rage and I no longer cared who had sold me out. I would kill them all - a sentiment Quan Chi apparently shared. Quan Chi recognized the carnage I had left behind as I practiced my new fatalities on the good people of the realms. He was impressed and offered to help me increase their power and effectiveness. All I needed do was fight beside the Forces of Darkness in Edenia. The means of enhancing my fatalities would reveal itself, and all my enemies would be there for the slaughter. Soon I'll have revenge. The time will come to finish them all."
