Jarek made his first chronological appearance in Mortal Kombat: Special Forces. Kano freed him and the other Black Dragon members (No Face, Tasia and Tremor) 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 as pawns in order 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 defeated and believed dead by Jax after their battle. He was the only Black Dragon member besides Kano to survive an encounter with Jax.
Shortly before the events of Mortal Kombat 4, Jarek fled 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 Lt. 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 push her off the cliff: in Sonya's ending, Jarek proceeds to fall to his apparent death; Jarek's ending picks up where Sonya's left off, with Jarek hanging from the edge of the cliff, who proceeds to reach up, grab Sonya, and toss her from the cliff; Jax's ending picks up following Jarek's, with Jax suddenly appearing, grabbing Jarek by the neck, holding him over the edge of the cliff, and dropping him. 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.
