All full-blooded Tarkatans are born with two demonic structures in their arms consisting of bone: these are the Tarkatan Blades. They span approximately four feet. Baraka uses them in all of his appearances to perform special moves as well as slicing through all who stand in his way. The signature weapon of the Tarkatan race first made its debut in Mortal Kombat II, and later was featured as a collectible Relic under the name "Baraka's Blade" within the Konquest mode of Mortal Kombat: Armageddon.
They are made into his weapon fighting style in Mortal Kombat: Deception, and remain that in Unchained and Armageddon. In those three games, every time Baraka starts a round after losing the previous one, if he's laying with his back to the ground, he will lift himself extracting the blades, causing them to be his first fighting style in the next round, instead of Silat.
The savage Tarkata later uses their signature to continue attacking their enemies without mercy in the animated series Mortal Kombat: Defenders of the Realm, and the second movie Mortal Kombat: Annihilation.
