The Tarkatan are a race of vicious mutant hybrids created by crossing the demons of Outworld and Netherrealm. Their inborn ferocity and ruthlessness makes them ideal shock troops for Shao Kahn's army, but one in particular rises to prominence amongst the fighting: his name is Baraka and even amongst his own vicious race, his bloodlust is legendary. Shao Kahn recruits him to be a lieutenant and lead an army of Tarkatan against Liu Kang's shaolin temple. That battle won, Baraka joins Kahn's forces for the second Mortal Kombat tournament. It was here that he met and partnered with Mileena, plotting to overthrow Shao Kahn at the climax of the tournament. Kahn's defeat stymied their plans and forced them to go their separate ways, Baraka retreating into a life of nomadic wandering.
Baraka's travels eventually brought him to Edenia and the sorcerer Quan Chi, who offered him a place in Shinnok's invasion force in the coming war. Again, Baraka's ruthless nature got the better of him and he planned to overthrow the elder god after the invasion's success. After Liu Kang and the Defenders of Earthrealm stopped Shinnok's invasion, Baraka's chance to rule was again lost and he fled to the ruins of Outworld until the rise of Onaga, the Dragon God. Again Baraka was recruited by an evil lord, but for the first time he wasn't planning on overthrowing him.
Baraka's first mission was to free his erstwhile partner and lover Mileena from the Edenian prison where she was being held. She was tasked with impersonating Kitana and leading the Edenian forces into a trap against a Tarkatan raiding party led by Baraka. The unexpected intervention of Bo' Rai Cho turned the tide of the skirmish and caused the Tarkatan party massive casualties. Baraka was enraged and planned to kill Mileena for her failure. Canon for the events that follow Mortal Kombat: Deception hasn't been fully established as Mileena's ending has her killing Baraka, but his ending states that she kills a double and he ambushes her, tearing her to shreds. As Mileena has been announced for Mortal Kombat (2011), it stands to reason that either her ending will be canonical, or Baraka's will have to be altered.
Baraka's battle lust overwhelms him and he goes on a rampage, killing Shao Kahn, Shang Tsung and Kintaro. He then leads his race out of the wastelands of Outworld and defeats what remains of Kahn's army, becoming the new lord of the realm.
Baraka's failure against Earth's Defenders places him in a precarious position in Shao Kahn's army. He serves loyally, biding his time to overthrow the Emperor. His chance arrives when Kahn's army defeats the Earthrealm warriors, but Kahn is severely weakened by his battle with Raiden. Baraka kills him in this state, but fears that followers were take revenge against him, so enters into self-imposed exile and spends the rest of his days wandering the wasteland of Outworld.
Baraka approaches Quan Chi's throne and learns that all the Elder Gods have been slain by Shinnok and that Quan Chi is the ruler of the Realm. Quan Chi then reveals that he and Baraka are the only ones who remain and Baraka demands to know what satisfaction can be gained from ruling a realm with no one in it. Quan Chi states that he merely desired power and now possesses it, even at the cost of everyone in the Realm. Baraka refuses to serve at the feet of a madman and lunges at the necromancer, stabbing him through the chest. It's revealed that this was a fake, however, and the real Quan Chi emerges, immobilizing Baraka and exploding him.
(possibly canonical) Baraka's forces have been decimated by Bo' Rai Cho. Believing Mileena betrayed him, he sent one of his warriors to meet with her while his other forces attacked Sub-Zero. When he arrived, he found that Mileena had killed the warrior that he sent and he ambushed her as she fled tearing her to shreds.
The power of Blaze courses through Baraka and he vows to never be a mere servant ever again. Summoning Shao Kahn and Onaga to the massive tower, telling them that they can either submit to his rule or die. They both attack him, but Blaze's power causes Baraka's blades to become massive and he stabs the two mighty warriors through their hearts. He then summons Mileena and tells her that she can join him as queen or suffer the same fate as the two dead lords. Mileena agrees.
The Kombat Rage left all its victims, but only strengthened within the savage hearts of the Tarkatan race. Their bloodlust became insatiable and their power even greater as they rampaged through the realms, dominating all in their path.
Mortal Kombat (2011)
At first, the Shokans and Centaurs are mad that Baraka had turned on Shao Kahn and killed. It turns into admiration when "Shao Kahn" changes to that of Shang Tsung. The sorcerer's deception as the emperor did not fool Baraka so easily. Now that all of Earthrealm is in Shao Kahn's control, the Tarkatans and Baraka himself were now more favored by Shao Kahn.
- Chop Chop Blades: Baraka crouches down and slices up and down in a vertical motion with both blades cutting his opponent to ribbons. (Appearance in every Mortal Kombat)
- Blade Spark: Baraka scrapes his blades together sending a metal shard towards his opponent. (Appearance in every Mortal Kombat)
- Head Sweep: A quick and simple blade swipe meant to decapitate his enemy. (Appearance in every Mortal Kombat)
- Double Kick: Baraka knees the man, then hits the man again with his shoe. (Appearance in MKII)
Baraka uses either one or both of his blades and with a single strike takes off his opponent's head.
Baraka extends both of his blades and easily pierces through his opponent's torso and lifts them off the ground.
Baraka strikes them once, twice, thrice, four times on the arms, legs, and head, then guts the unlucky victim and pulls his torso out.
Baraka lodges a blade from his forearm into his opponent's stomach and lifts them above his head. He then starts to spin them on one blade, using his other to dismember and decapitate them.
Baraka stabs both his wrist blades into his opponents stomach and lifts them off the ground. He removes one only to stab his victim through the throat, then following up with an jab through the eye and out of the back of his enemy's skull. He finishes kicking the limb body off his blade.
Baraka's fighting style is Silat (as seen in Mortal Kombat Armageddon and Mortal Kombat Deception), a Indonesian martial-arts style that uses jabs from hands to bladed weapons (which maybe why Silat is Baraka's fighting style of choice-he has blades coming out of his arms, after all).
Baraka also uses Blades as his primary weapon; this is arguably the best weapon style in the games which have weapon styles, due to the fact that the weapon style can seamlessly change from one fighting style to another, resulting in quick combos and devastating damage.
