Major Jackson "Jax" Briggs (U.S.A.) is a cybernetically-enhanced soldier who is the leader of the Outer World Investigation Agency (O.I.A.), Earthrealm's Special Forces unit, in the Mortal Kombat fighting game series. He made his debut in Mortal Kombat II.
Jax made his debut in Mortal Kombat II. He is portrayed as an archetypical African American hero. In the Special Forces' chain of command, he is Sonya Blade's direct superior and the catalyzing force of Sonya's impulsiveness. Jax is clear-headed, careful and always keeping a watch on what his men are doing. When the need arises, he is a beast on the battlefield with the attitude and ferocity of a lion. He unscrupulously makes use of the most advanced technology to improve both himself and his unit. He is responsible for the crime lord Kano's disfigurement, forcing him to wear a metal plate over a portion of his face.
Jax is depicted as an African American man, having dark skin, black hair and brown eyes. Jax's most striking feature is his impressive muscular upper body build, keeping his torso bare in all but one of his appearances. In his first appearances, he wore karate pants and boots. From Mortal Kombat 3 and onwards, he wears a pair of bionic armor-plating that covers and protects both of his arms.
It is not known whether his arms were replaced or upgraded in the original storyline. However, it is possible that he may have used bionic implants until the events of Deception, where he may have willingly had his own arms removed in favor of mechanical replacements. In the alternate timeline of MK 2011, he was forced to use metallic arms in order to survive, after having his organic arms telekinetically dismembered by Ermac. In MKX, he wears a camouflage vest with his last name Briggs on his right upper vest pocket with his left upper pocket acting as a storage for his cigars and he still wears his dog tag around his neck, along with two more additional pockets near his abdomen. He has an American flag wrapped up and tied around his upper right arm and he wears green pants with some additional color of black on them and wears black army boots.
Powers and abilities
Due to his membership in the army, Jax is quite a hardened soldier in the battlefield. He is known to show incredible ferocity while staying focused at the same time. Jax's most prominent attribute is his massive upper body strength. His physique and strength are so powerful that he is able to crush human heads with ease and shake the earth with a single punch. From Mortal Kombat 3 onwards, Jax utilizes cybernetic strength enhancers to further augment his already impressive physical power. These implants also carry portable missiles and a piston-like mechanism to increase the force of his blows. His bionic arms may have made him the most physically powerful man on Earth, if he wasn't already that strong.
Aside from his kombat skills, Jax is also a competent technician and scientist, having been in charge of the portal development technology that the Outworld Investigation Agency uses to move between realms, and also utilized his smarts to restore Cyrax's free will.

Movie and TV Appearance
Jax appears briefly in the first Mortal Kombat movie, in which he accompanies Sonya on the raid on Kano's club and unsuccessfully tries to stop her from boarding Shang Tsung's boat near the beginning of the film. He was played by Gregory McKinney.
Jax appears in the animated TV series Mortal Kombat: Defenders of the Realm, he was among the leading characters voiced by Dorian Harewood. He was always in a good mood and always ready to go into battle whenever Outworlders invade. In the episode Acid Tongue, he loses his confidence when Komodai spits acid on his cybernetic strength enhancers, and he uses his chi to fight Komodai at some ruins to rescue Sonya. Another episode, Abandoned, had him leaving the team only to be captured by Shao Kahn's forces in an attempt to get information on the location of the MK headquarters. This episode also explores the deep friendship and care between Sonya and Jax, who revealed as a child he was made fun for being fat.
Former American Gladiators actor Lynn "Red" Williams plays Jax in Mortal Kombat: Annihilation. He is recruited by Sonya to join the Earthrealm warriors in their stand against Shao Kahn's forces. He fights Cyrax and later defeats the Centaurian, Motaro (played by fellow Gladiators alumnus Deron McBee). His relationship with the technological enhancements he uses is explored to a small degree.
Michael Jai White plays Jax in Mortal Kombat: Rebirth. In this short film, he informs top assassin Hanzo Hasashi about serial killers in an underground tournament led by Shang Tsung. He tries to convince Hanzo to join the tournament.
Michael Jai White reprises his role as Jax in Mortal Kombat: Legacy.
In this continuity, Jax serves as a detective for the Deacon City Police, working alongside Sonya Blade and Kurtis Stryker, while maintaining his close relationship with Sonya and his intense rivalry with Kano.
In the first episode of the online series, Jax is part of a conference going over the details of Sonya's transmission that reveals the location of Kano and the Black Dragon's hideout. while Jax wants to move in immediately, Stryker urges caution and that they follow protocol and wait for Sonya to confirm the intel. Lacking patience when it comes to Sonya's safety, Jax declares, "fuck protocol. I'll go myself." Stryker reluctantly follows his example and orders their team after him.
Jax, Stryker and their team arrive at the Black Dragon's warehouse hideout, but are soon ambushed, with Jax being the first to realize this as he sees one of the S.W.A.T. officers get struck with an explosive. Jax then sees Kano arrive with a large group of Black Dragon members and a massive gunfight erupts.
Though Stryker wants to know how Kano knew they were coming, Jax says that now is not the time to ask that and tells him that he is going after Sonya while requesting cover from Stryker. Working together, the two successfully take out several Black Dragons, with Jax himself using a combination of martial arts and weapon fire to dispatch them. Jax then gets in a shootout with Kano but when both run out of ammo, Jax chases after Kano to an upper section of the warehouse.
There, the two engage in hand-to-hand, being roughly evenly matched, though after Kano deals Jax a low blow, Jax grapples with him over control of an explosive launching weapon, which fires at their feet. The two narrowly dodge the ensuing explosion.
In the next episode, Jax recovers and resumes his chase after Kano, cornering him and demanding Sonya's location. The two fight again, and Kano manages to briefly get the upper hand when he strikes Jax with a glass bottle. Kano then boasts about torturing Sonya, infuriating Jax.
In a stunning display of barely controlled rage and skill, Jax single-handedly defeats Kano, never allowing the mercenary to lay a single hit on himself, before punching Kano so hard across the face that he knocks out his right eye and collapses part of his skull. Jax then collapses to his knees, exhausted, when Sonya appears, taking out a Black Dragon who had just thrown a grenade.
As the two spot the grenade, Jax rushes over to Sonya and shields her from the ensuing explosion.
Though not seen again, Stryker reveals that Jax survived, but was badly wounded, sustaining severe injuries to his back and arms. Stryker then reveals that Jax is in surgery at the D.O.D. and assures Sonya he will be fine.
Michael Jai White did not return for Season 2, leaving Jax absent from the tournament.

- His original name was going to be Kurtis Stryker. Midway later recycled that name to create a new character in Mortal Kombat 3.
- In his MK vs DCU ending, Jax sustained severe injuries after the World Merge Crisis. So to save his life, he augmented more of his body with cybernetics, becoming the Earthrealm version of DC's Cyborg.
- Jax was originally conceived as simply a kickboxer, but the idea was scrapped due to potential similarities to Balrog, Sagat and especially DeeJay from the Street Fighter series. Then he was given a yellow martial arts gi and big metal hands that clanged upon impact. However, the outfit concealed much of the impressive physique of actor/bodybuilder John Parrish, so he simply went shirtless with long black tights.
- Game footage was actually shot with Jax wearing the yellow costume. Parrish accidentally split the pants during filming.
- During photography for MK3, Parrish wore a gold chain around his neck, which was digitally editted out of all sprites made from the filming.
- Jax's body can be seen in the introduction of Mortal Kombat Deception, located on the top of the stairs leading to the Soulnado chamber.
- In Armageddon's opening scene, Jax is hit by Shao Kahn's Wrath Hammer, probably hitting the back of Jax's arm because you can hear a metal-to-metal like sound.
- Before Sonya existed, Jax was originally conceived as a character and possessed her scenario for the first Mortal Kombat. However, since there were no female characters in the original roster at the time, Sonya was created and she inherited his storyline of pursuing Kano and entrapment on Shang Tsung's island.
- In the MKII comic book, he challenged Kintaro in battle.
- According to early production shots of Special Forces, Jax's code name is "Cobra."
- Hakim Alston, who portrayed Jax in Mortal Kombat: The Live Tour (1996), played an Outworld warrior who was defeated by Liu Kang (Robin Shou) in the original MK movie a year earlier. He also co-starred alongside MK game actor Ho Sung Pak in the syndicated television series WMAC Masters.
- In Mortal Kombat: Armageddon, knocking Jax off of the Sky Temple will make him yell, "Oh my god! This is not happening to me!"
- Michael Jai White, who plays Jax In MK: Legacy, was originally cast to play Jax in Mortal Kombat: Annihilation, but had already began shooting Spawn instead.
- Jax's fighting stance from Mortal Kombat 3 is similar to that of the male human ninjas (minus Reptile, Rain, and unmasked Sub-Zero) from their UMK3/MKT incarnation. It also comes from the Shaolin Fist fighting style.
- He assists the player (as either Liu Kang or Kung Lao) during the boss fight with Kano in Mortal Kombat: Shaolin Monks. After Kano is killed, he and Sonya decide to leave Outworld and gives the player a health upgrade to aid in defeating Shao Kahn. He is the only CPU ally in Shaolin Monks to not be playable.
- It is stated in the Konquest mode of Mortal Kombat: Deadly Alliance that it was Jax who caused the injury that led to Kano wearing his metal face plate before the events of the series.
- Jax appeared in an advertisement for Chrome Bling.
- In MK 2011, Jax can be seen smoking a cigar at the Wu Shi Academy, when he is talking to Raiden. He is also seen smoking during MKX, implying it is a regular habit.
- In the track "MK3 Audio Tour" (4:11) from Mortal Kombat Musik: MK3 & MK4 Arcade Videogame Original Soundtrack, it seems like Jax had an unused fatality (in the track, Jax hits the opponent, then the latter bounce many times before exploding), although he is simply performing the Bell Tower Stage Fatality.
- Interestingly, in Mortal Kombat vs. DC Universe, Jax is never fought once in the Mortal Kombat story.
- In a MK 2011 trailer, Jax uses his Missile move, but it is not present in the game.
- In certain cutscenes and fatalities in MK 2011, Jax has a submachine gun on his back. It sometimes even disappears after the camera changes angles, hinting that the machine gun was a scrapped concept for his character.
- In the indie fighting game Skullgirls Encore, the 13th alternate color palette of the character Beowulf directly references Jax's MK3 incarnation.
- In a couple of Jax's Mortal Kombat X intros, he says "I'm too old for this shit!". This is a reference to the catchphrase of Officer Roger Murtagh from the buddy-cop action film series Lethal Weapon.
- In MKX's character select screen, when playing a match in Jax's Carl Weathers outfit and Johnny Cage's commando outfit, after selecting a stage, Johnny will say "You son of a bitch!" and shake hands with Jax. This is a recreation of the handshake scene between the characters Dillon and Dutch in the movie Predator.
- In the first Mortal Kombat film , Jax's name was misspelled 'Jaxx' on the ending credit.
- Despite killing Tremor in the original timeline, Tremor and Jax are still aware of one another and show hatred for each other in MKX.
- In MKX, Jax is one of the few characters whose fighting style is altered by the addition or removal of a weapon.
- Jax is one of five characters to have an alternate version of a Brutality. The other three are the Erron Black, Predator, Tremor, and Reptile.
- In MK 2011, performing a Fatality that involves skinning on Jax will show muscles in his arms.
- When Rain's X-Ray move is performed on Jax, bones can be seen in his arms. However, this is most likely a gameplay mechanic.
- In MKX, when a Fatality that involves the arm area is performed on Jax, muscle will show in the spots where it happened. When a Fatality or a Brutality is performed that involves the opponent being reduced to a skeleton, bone will show. These are all most likely gameplay mechanics.
- When Rain's X-Ray move is performed on Jax, bones can be seen in his arms. However, this is most likely a gameplay mechanic.
- Also in MK 2011, when Jax performs his X-Ray, the opponent's intestines crack, which makes no logical sense.
- Similar to Erron Black and Cassie Cage in MKX, Jax never reloads his machine gun or rocket launcher in his Heavy Weapons variation, giving it the illusion that both weapons have unlimited ammo.
- Jax rocket launcher in his alternate version of his secret brutality defies logic based on how the rocket is fired and where it travels in the end.
