Jax made his debut in Mortal Kombat II. He is portrayed as an archetypal 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 at his disposal 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.
In the current timeline, Jax perished at the hands of Sindel and was revived as a revenant by Quan Chi, whom he was forced to serve. Although he was eventually freed and brought back to life, his experiences as a revenant left him traumatized, reducing the once fierce warrior to a broken shell of his former self. Sometime afterward, he married a woman named Vera, with whom he sired a child, Jacqui. Jax was opposed to her joining the Special Forces, as he did not want her to experience the same horrors and traumas he had. In Mortal Kombat 11, it is revealed that his wife had died, breaking Jax even further and causing him to become a recluse. This gave Kronika the opportunity to recruit him in her goal of resetting the timeline, promising him the ability to stop Jacqui from joining the Special Forces. Whilst initially working alongside Kronika, he was convinced to return to the side of good by his past self, his daughter, and Raiden, turning upon his ally and joining the fight against her.
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.
In MK11, an older Jax wears a brown leather vest with his last name Briggs on his back, a black tanktop from the inside and a two dog tags, an olive green pants along with kneepads and a black army boots. He later wears clothes that looks similar to Kronika after being manipulated. A younger Jax wears a black army vest, a purple camouflage pants with straps as well as his boots. He is also clean shaven in contrast to his present counterpart who has fully grown beard.
Powers and abilities
Due to his membership in the army, Jax is quite a hardened soldier on 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, energy enhancers, nanokinetic metalmorphation and a piston-like mechanism to increase the force of his blows. In Mortal Kombat Unchained he has long since replaced his flesh & blood extremities with fully bionic limbs that replicate all the functions of his enhancement mods. Possibly making him the physically most powerful man on Earth, if he wasn't already that strong.
Aside from his kombat skills, Jax is also a competent technician, scientist and engineer, having been in charge of the portal development technology that the Outworld Investigation Agency uses to move between realms on top of the special development of the SF's bionic enhancement program. Having utilized his smarts to restore Cyrax's free will.
Even before receiving his upgrades, Jackson Briggs' muscle power was great enough for him to create purple shockwaves and launch them at the enemy.
He would often focus his dynamism into causing earthquakes by slamming his fist into the ground. After getting his arm braces, the cybernetics seem to augment his natural force output. Strengthening his tremor based abilities while also increasing his overall raw power.
In later Mortal Kombat games, the cybernetics would come with further augmentations, like a rocket-propelled punch or a plasma shell discharge which he could launch individually or consecutively from both fists.
In various Mortal Kombat games, Jax would also incorporate modern weaponry into his fighting style to compliment the cybernetic augmentations he'd received. Often times employing sub-machine guns, grenade and rocket launchers as well as RPG's along with his melee. In Mortal Kombat 11, Jax has able to heat up his Bionic Arms every time he lands a punch, doing this will increase the damage of his bionic arms and gain an ability to shoot projectiles from his fist.

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.
Mortal Kombat (film)
- "Trust me, Sonya."
- "Nothing says that creep at the club wasn't lying his ass off. Kano could be a thousand miles from here by now."

Part 1: Mortal Kombat 11
- "Weird, isn't it? Not being in charge." (to past Sonya)
- "That, and having daughters our age."
- "At least she's not an actress."
- "Why would the Netherrealm want to bust up your alma mater, Liu Kang?"
- "Man. These arms are an upgrade. It'll be payback time, next time I see Ermac." (to Jacqui)
- "I imagine 'future me' is out kicking ass with these right now."
- "Sounded horrible. Can't imagine becoming Shinnok's puppet. But she says I come back for it."
- "The love of a good woman? Like the sound of that."
- "Now that's what I call a miracle."
- "I'll go, too."
- "We need to get Sonya back."
- "Then what's her next move?"
- "How's the view?"
- "Oh, you'll know it when it comes."
- "For the first time in a while, in control."
- "I got tossed into the deep end of this world of gods and monsters. But now, knowing my future, I feel like I've finally come up for air."
- "Those bad things that happened to me... I mean, will happen to me? Like Raiden said, it's gonna be different."
- "Isn't this good news?"
- "Jacqui, I can't pretend I get all this cosmic time stuff, but I do know you are here for a reason. You're not just some random accident."
- "Here we go again." (Upon arriving Shang Tsung's Island)
- "When I was here at the tournament, there were people everywhere."
- "These guys looked a lot younger. Seems like only yesterday..."
- "Kinda hoping Raiden's wrong about the Well of Souls. I don't wanna be here longer than we--"
- "How many?"
- "Give me ten seconds with this guy." (If the player chooses him)
- "Got the wrong Jax. I haven't been a Revenant."
- "And I never will."
- "Times are changing, Kabal." (After defeating Revenant Kabal)
- "You're done messing with the Well of Souls."
- "I'll take the lady in green." (If the player chooses him)
- "Was a time when you knew who to fight for. But between Quan Chi and Kronika, your mind ain't right."
- "I'll take my chances with Raiden." (After defeating Revenant Jade)
- "This way."
- "Thankfully minus Goro. Shang Tsung kept me locked up here, back at my first tournament. Never thought I'd be back..."
- "Couldn't tell you. I was pretty beat up. It's all a bit hazy." (Told Jacqui he couldn't remember the Well of Souls)
- "That crown. Five bucks says it's Kronika's."
- "There's no way that thing's unguarded. Let's grab-and-go before whoever's on duty gets back."
- "The first Sub-Zero. Scorpion ripped out his spine. Left in a heap upstairs, in Shang Tsung's old throne room." (Replies when Jacqui ask who Noob Saibot was)
- "Hang on, Jacqui. I got this." (If the player chooses him)
- "Got that right."
- "I'm just that tough."
- "Guess Ermac's not the only one who's weak." (After defeating Noob Saibot)
- "C'mon. Let's get that thing and get outta here."
- "Mind. Blown." (When he sees his future self for the first time)
- "I'll give you one guess."
- "By destroying the universe?"
- "You're talking nonsense, man. You raised a fine daughter. She's one helluva soldier."
- "Hang back, kid. I know I wouldn't wanna fight my Dad. How 'bout we keep this between me, myself, and I?"
- "Never thought I'd stoop so low."
- " I know you suffered. You still do. But you don't betray your unit, and you sure as hell don't betray your family."
- "There's gotta be a way to make this right." (After defeating his future self)
- "Trippin'. You?" (To Jacqui)
- "At least he's the devil we know." (To Cetrion)
- "Cassie beat Shinnok." (To Jacqui)
- "Maybe we have our own magic."
- "I can't let you do--" (If the player chooses Jacqui)
- "Stand back. We don't know what this thing'll do."
- "Only got to wear this thing long enough to beat you."
- "Mission accomplished." (After defeating Cetrion)
- "The hell're you doing?!"

Part 2: Aftermath
- "Hands over your head, Shang Tsung."
- "About time we had some good news."
Part 1: Mortal Kombat 11
- "Oh, come on... Damn it!" (When searching for his phone)
- "Come on, come on..." (Trying to connect with his daughter)
- "That's awfully generous, seeing as we've never met."
- "Your plan?"
- "Jacqui, wait."
- "Giving you the life you deserve."
- "Restarting it, not destroying it."
- "Being a Revenant. The years I lost, the things I did. Your Ma held me together. But I was never the father you needed."
- "She shouldn't have been a soldier!" (To past Jax)
- "I never wanted you out there, taking those risks. If I hadn't fall apart, you wouldn't have felt the need to enlist." (To Jacqui)
- "Please. Give that crown to me. I don't want to hurt anybody."
- "You don't know how bad it gets. Losing your arms was just the beginning." (To past Jax, before facing him)
- "Nobody here wants to hurt anyone. Now, please. Don't let this happen to our girl."
- "Now bring Jacqui back."
- "I'm not doing this to you, Jacqui. I'm doing it for you. I love you." (To Jacqui)
- "I'm not usually surrounded by so many friendly faces."
- "I don't want to fight, but I've got to." (To Raiden)
- "For Jacqui's sake and mine."
- "But--No. She's Cetrion's mother." (After Raiden revealed the truth about Kronika)
- "Which'll only happen if the realms keep on fighting each other."
- "What have I done? I'm a fool."
- "I'm sorry, Raiden. I promise to make this right."
- "Candy ass bitch."
- "What happened to Raiden?" (To Fire God Liu Kang)
- "This means I'm sorry, Jacqui. And hell yeah I'm back." (Apologizing Jacqui Briggs)
Part 2: Aftermath
- "Do me a favor, Fujin, and take one giant step back."
- "You too, sorcerer."
- "Makes sense we meet again down here."
- "Where you caged me up, beat me within an inch of my life. The hell if I ain't gonna return the favor."
- "That's a card you can't play, Fujin."
- "Not when you're buddied up with Shang Tsung."
- "Dammit, Fujin, you know what I've suffered. Kronika's my one chance to prevent all that. Not just for me, but for Jacqui. For Vera."
- "Shit. You're a god. Ain't no way you get how this feels."
- "Well, I'll be. Maybe you do get it."
- "Ease up, baby girl."
- "We're all on the same side against Kronika."
- "Go! I'll cover him."
- "There's the Sindel I remember."
Mortal Kombat Legends: Scorpion's Revenge
- "Wait a minute."
- "Now we can go."
- "She didn't kick you in the nuts, did she?"
- His original name was going to be Kurtis Stryker. Midway later recycled that name to create a new character in Mortal Kombat 3.
- In Mortal Kombat 3, Jax adapts cybernetic prosthetics over his normal arms to increase his physical power. His normal arms are left unchanged underneath them, allowing him to remove them if necessary.
- The story behind Jax's prosthetics were to be expanded upon in the original plan for Mortal Kombat Special Forces, which chronologically predates his first appearance in Mortal Kombat 2, where he appeared without them. The exposition was one of the many ideas removed from the final version of the game, showcasing Jax using the prosthetics with no explaination for the chronological discrepency.
- In both Mortal Kombat Annihilation and Mortal Kombat: Defenders of the Realm, Jax is forced to discard his prosthetics and fight using his bare strength.
- In the new timeline, Jax instead has his arms completely destroyed by Ermac during the second tournament, necessitating complete cybernetic replacements.
- 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 edited 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 begun 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 faceplate before the events of the series.
- Jax appeared in an advertisement for Chrome Bling.
- Beginning with MK 2011, Jax is frequently shown smoking cigars.
- 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 misspelt '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 Erron Black, Predator, Tremor, and Reptile.
- Jax's rocket launcher in the Heavy Weapons variation is based on the M72 LAW, though Jax actually uses it backwards; the extending part is the exhaust of the real weapon. His SMG appears to be the same fictional (although based on the real-life MP5K) weapon he uses in MK: Special Forces.
- Jax is the only past iteration of playable characters in MK11 Story Mode, whose mirror match against his future-self is normal, despite the latter iteration had an experience as a Revenant in MKX.
- Counting Johnny Cage’s mirror match between past and future selves, Jax is the second character who has a mirror match between past and future selves who are both humans.
- Jax, Johnny Cage and Kano are the only known characters to have team-up cutscenes between their past and present selves in MK11 Story Mode.
- Jax's friendship in MK11 is a reference to an internet meme of a Moldovan musician and composer Sergey Stepanov, who was commonly known as the Epic(Ultra) Sax Guy. It also related to video clip and Eurovision entry of Moldova Hey Mamma by Sunstroke Project in 2017 where Stepanov is member of there.
- In Mortal Kombat 2011, Mortal Kombat X and Mortal Kombat 11, Jax does not possess a character-specific skeleton or cavader to showcase his mechanical arms, causing bone or muscle to appear as his arms instead should his arms be ripped off or his body stripped of its flesh.
- MK 2011, when Jax performs his X-Ray, the opponent's intestines crack, which makes no logical sense.
- In MK11, during his Fatal Blows, when Jax punches his opponent to the face and gut five times, only one of his arm will heat up, but before he claps his opponent, his other arm already heats up as Jax only used his other arm for grabbing his opponent.
- In MK11, if Kitana's Deadly Lips Brutality is performed on him, the character will explode but his mechanical arms will remain static in the air.
