One of the few "urban" characters in the Mortal Kombat franchise, Kobra is an arrogant, bloodthirsty martial artist and a fresh recruit for the new Black Dragon clan (led by a former member of the original Black Dragon clan, Kabal). He is often paired up with fellow recruit Kira (in which it is implied that they have a romantic interest; however, their endings often end in one killing the other).
He first appeared in Mortal Kombat: Deception, using his Shōrin-ryū and Kickboxing fighting styles (along with Kali Sticks as weapons). His special moves include a charging "Windmill Kick", a quick dashing punch (which can either be engulfed in flame or be appeared from behind his opponent through teleportation), and a fireball attack that can be standing or crouching (similar to Liu Kang's fireball attacks). His last appearance in Mortal Kombat: Armageddon trades the Kali Sticks for a Machete and removes the Shōrin-ryū fighting style (which is instead used by Johnny Cage).
A skilled martial artist, known as Kobra, trained in the martial arts wondering how his training would be effective in a real fight. After killing scum in the back alleys of New York City, he became a bloodthirsty criminal himself (intimidating, looting, and killing civilians). After being captured by the police, he is broken free by Kabal and Kira in a daring raid, who recruit him into the new Black Dragon clan. Led by Kabal, the new Black Dragon clan worked for Havik, the cleric of Chaos. Kobra and the gang spread disorder throughout the realms.
Shortly before the events of the Battle of Armageddon, Kobra and Kira encounter the half-Edenian, half-God Taven while guarding a bridge in the Botan Jungle (in Earthrealm) close to the Black Dragon stronghold. As Kira retreats to gather the clan's forces, Kobra fails to stop Taven from crossing. During the legendary Battle of Armageddon, Kobra (along with Kabal and Kira) join the Forces of Darkness. Like most of the combatants in the epic battle, Kobra is killed in action (though of unknown cause).
Kabal brought his two recruits, Kira and Kobra, to the siege against the Dragon King Onaga. Kobra wanted to join the fray, but Kabal held him back. After Onaga was defeated, Kabal gave the order to charge against the victors, leaving no survivors.
After Kobra defeated Blaze, he demanded that the Elder Gods declare him Lord of the Realms. They do so reluctantly, and requested Kobra to choose a lady to rule by his side. Kobra chooses Kira, who then becomes a goddess of death. With a kiss, Kira reduces Kobra's body to dust.
