Ultimate Mortal Kombat 3/Jax

From SuperCombo Wiki




After failing to convince his superiors of the coming Outworld invasion, Jax prepares to covertly for the future battle with Kahn's minions. He fits both arms with indestructible bionic implants. This is a war Jax is prepared to win.

Strengths Weaknesses
  • Great Rushdown: Jax's pressures consists of kara jabs, mid auto combo staggers and sweeps.
  • Good Zoning: Jax can zone effectively with Missiles and Ground Pound.
  • Safe Sweep: Jax's sweep is completely safe on block. Jax can counter glitch jabs easily using sweep. Opponents will often become frustrated by Jax's sweep and attempt to approach by air. Jax can air throw in this situation.
  • Great Throw: Jax's throw does additional damage utilizing Multislam. Jax's throw can do up to 24% if all Multislam hits are used. Ordinary throws do around 15%. Jax can also decide if he wants side switch during his throw or not. Most throws are back throws by default.
  • Air Throw: Air throws are generally great. Jax's air throw is extremely good in combination with his safe sweep.
  • Large Hurtbox: Jax has the largest hurtbox in the game. Expect to get hit with character specific optimal juggles.
  • Corner Trapped Crouching: Jax can be corner trapped crouching by everyone except Lao, Male Ninjas, Shang and Sheeva.
  • No Sweep Punish: Jax's Dash Punch is fast enough to punish sweep, but unfortunately it is disabled in this instance. Dash Punch can still be used to punish blocked LKs and HKs.
  • Highly Dependent on Glitch Cancel: Jax's main auto combo can whiff on block without Glitch Cancel.
  • Tall Running Hurtbox: Jax cannot run under instant air projectiles like Kabal's instant air Gas Blast or Mileena's instant air Sai.

Move List

Basic Moves

His LP run jab game is questionable because they hit slightly higher, allowing more chance for him to be uppercut or ducking LKed, his HPs hit high as well, and set up easy air juggle aaHPHP, JK, air throw for about 44%. His standing HK has good range and moderate height, excellent for anti airing half screen jumpers. His standing LK also has good range and positioning. His sweep is among the fastest in the game, abuse it. His ducking LK is a hair slower than some, but has good distance again. His RH has very limited range, but good height, useful for run under RH situations. His uppercut has a lot of height and range, but some characters can slip through it on cross ups, which is when you should for an anti cross up backbreaker. All of his air attacks are very good.

Kombo Strings

  • HK, HK, B + HK (19%)
  • HP, HP, BL, LP, B + HP (27%)
  • HK, HK, D + HP, HP, BL, LP, B + HP (33%)

Special Moves

Gotcha Grab

  • F, F, LP (tap LP for multiple hits)
  • 21% Damage
  • The Gotcha Grab is a sudden, fast move that is very safe to throw out randomly and the only real way to punish it consistently is to sweep when it comes out. There are obviously other ways to scout and punish it, so don't rely on it as a certain way to catch someone but it often does get people off guard and against blind rush down. With exact timing you can stick the Gotcha Grab in his 7 hit autocombo midscreen against Jax, and unmasked Sub-zero for a bit of extra damage that isn't really worth the effort, 51% with a punch starter, vs guaranteed 47% on everyone with a sweep instead, 47% with a LK on most characters, and 48% with a HK on a bunch. It is very useful for punisher combos, and in the corner off his autocombo, which can be extended significantly against many characters.


  • Single: B, F, HP
  • Double: F, F, B, B, HP
  • 10% Damage
  • Single and Double Missiles are great zoning moves because they take up a lot of space and move Jax backwards, so if someone jumps over one he is generally safe. In UMK3 they added charge time to the single missiles, and this also effects the doubles. If you fire a single missile, you have to wait a few seconds before you can fire a double, or another single, and vice versa. They were too broken in MK3 and decided to add this limitation to balance him. You can still use the double somewhat for zoning, or avoiding certain attacks with extra protection. You can mix the single missile with run jabs, and the double missile will hit teleporters from full screen as they go off screen.

Dashing Fist

  • F, F, HK
  • 13% Damage
  • The Dashing Fist is a sudden move that can be useful to an extent, used as a wakeup particularly when getting up. Try to buffer the move without making your movements known as it is easily scoutable in that situation. In certain set ups, the Dash Fist will make Jax bounce off the opponent and move backwards, making him slightly safer than he would be normally. Do not over abuse it because it hits high and is easily duckable and punishable. It is possible to use this move to get you closer to an opponent as a method of dashing, but it is inadvisable, and you can also use it to extend corner combo juggles. It is also useful to get you out of certain situations and go back into zoning or sweeps. Sometimes you can use it as anti air and it generally makes Jax wind up right next to the opponent so you can go into run jabs, a combo, or sweep strategies as well. When used as anti air it can cause some glitch type scenarios where it will make Jax and his opponent push off eachother in opposite directions either facing towards or away and can create some opportunities for other tactics. There is no limit as to how many Dash Fists you can do in a juggle, nor is there a time limit inbetween so you can literally just frames a couple of them in a row in the corner as a humiliation juggle after his 7 hit combo.

Ground Pound

  • Hold LK for 3 seconds, release
  • 12.5% Damage
  • The Ground Pound is another returning move from MKII, but it was given more start up frames to balance it, however it is still useful, and unblockable and only avoidable by jumping. It keeps your opponent on guard at all time and might put them in bad situations when they might not want to be in the air. Not many people actually use this move in UMK3 because of how much slower it is than the MKII version, but when used properly it becomes an annoying factor in a match, particularly if you time it to connect as soon as they hit the ground on a jump, this will force them to jump if they see it coming and they have to immediately decide whether they are close enough to counter the ground pound with a jump kick or a jump punch start to combo, straight up, or backwards. If you time and space it right, you will be on the advantage when they land on their second jump and be able to once again resume your now nasty, cheesey sweeping and back breakering techniques.


  • Block (in air near opponent)
  • 16% Damage
  • The Backbreaker is his golden move, because it is perhaps the most useful move in his arsenal, even though simplistic in usage and design. Air throws have tremendous zero frame priority in MK like regular throws in just about any game, including MK itself, but you can't avoid them in air or tech hit, and they generally do significant damage, in the mid-high teens and this is for one move that sets up tactical scenarios, generally accompanied by a JK before hand, increasing damage to about 30%. Whenever someone tries to cross up jump punch or jump kick you as you are sweeping them to a bitter end, anticipate it, and immediately, unhesitantly and committedly, jump forward, or straight up and tap block, and you will backbreaker them right back to the ground, then immediately return to the sweep fest. This tactic is also used with Kano and perhaps even more so. Even when you aren't sweeping, watch for any possible chance to get a backbreaker because it is also a psychological move. It makes people rethink what they are doing if you get them with it, 2, 3 or 4 times in a row because they think for some reason their cross up is going to work this time. Always remember to tap block a few times while you are in the air even if you aren't in a natural situation where you would instinctively backbreaker someone because chances are you'll hit it. Remember that Robot Smoke's radius for his air throw is very large, pretty much 360 degrees around him while Jax's has a bit less area to deal with.


  • Tap HP during a throw
  • 6% Damage per slam
  • The Multislam is simply a special throw, in which you perform a normal throw, and tap HP several times to get 3 more slams. There isn't much more to it other than you can go back into sweep tactics after it!

The Basics


As Jax

He's a sweeper, a zoner, a back breaker-er, and ground combo crusher. He's got a lot of options but he struggles against teleporters and other top tier characters. Take advantage of old tactics like standing HKs, ground pounds, sweeps, watch for cross ups and hit the back breakers, sweeps, keep away with missiles, sweeps, rush down with run jabs and the 7 hit combo but be careful on male ninjas and some other characters because often times the 7 hitter will whiff on the D HP (HK, HK, D HP) leaving Jax open for a free counter, in some cases disastersouly damaging because he is the easiest character to juggle, oh yeah and sweeps. Play as cheap as possible with him, perhaps even turtle or read other players, and play safely because he can be annoying to rush down due his range.
