Kung Lao is a former Shaolin monk and a member of the White Lotus Society. He stands in the shadow of his great ancestor, the Great Kung Lao, but unlike his great ancestor he has no desire to be champion and would rather live a life of peace. As well, he has sought counsel from master Bo' Rai Cho. Of the Earthrealm warriors, Kung Lao is the most outspoken pacifist, although he will not hesitate to severely punish those who attack him, Earthrealm, or his friends. His trademark is his Razor-Rimmed Hat, which he can employ quite powerfully and effectively in combat. Many of his fatalities involve the use of his hat to some extent.
According to MK co-creator John Tobias in a 1995 interview with EGM, Kung Lao's hat was inspired by the 1964 James Bond movie Goldfinger, in which a character named Oddjob threw his derby hat as a weapon.
Kung Lao possesses similar abilities to Liu Kang when it comes to strength, agility and martial arts. However, those are not his most deadly weapon. Kung Lao's preferred weapon of choice is the razor-edged hat that he wears all the time. The hat is usually utilized to instill fatal and amputating blows, mainly in decapitation. Kung Lao appears to have absolute control over the hat as he is able to throw whilst it moves in circular directions instead of straight ahead.The hat also appears to have supernatural properties: No matter how far he throws it or where it'll end up, the hat will always materialize back on Kung Lao's head like an instant boomerang. He appears to also have some degree of teleportation as well.
Wind Teleport: Kung Lao goes to the ground and reappears behind his opponent. It could be followed by multiple moves. In MK 2011 it is named Teleport and can be followed by a punch, throw, or kick. (MKII, MK3, UMK3, MKT, MKG, MK:SM, MK:A, MK 2011)
Double Pass Teleport: Kung Lao passes twice before appearing behind his opponent. (MKT, MKG, MK:SM)
Hat Throw: Kung Lao hurls his hat at the opponent. In MK 2011 this is called Hat Toss. His hat can also be directed upwards or downwards in MKII, MKT, and MK 2011.(MKII, MK3, UMK3, MKT, MKG, MK:DA, MK:SM, MK:A, MK 2011)
The enhanced version is called Ultimate Hat. Kung Lao throws the hat underhand and it slices into the opponent, spinning for a few seconds. This is the MK3/MKT version of his Hat Throw, & it can't be directed as the regular version can.
Ground Hat: Kung Lao throws his hat on the ground, causing it to spin towards the opponent. (MK 2011)
The enhanced version is called Grinding Hat. The hat will stay on the ground for a second before launching into the air.
Whirlwind Kick: Kung Lao flies towards his opponent spinning like a tornado, doing multiple kicks that knocks them down. (MK:DA, MK:A)
3D Shield / Whirlwind Spin: Spinning like a tornado, Kung Lao knocks his opponent into the air. In Mortal Kombat Trilogy and Mortal Kombat Gold he could move while spinning. In MK 2011 this is called Spin, & it is now a major component of his gameplay as a launcher. (MKII, MK3, UMK3, MKT, MKG, MK:SM, MK 2011)
The enhanced version is called Cyclone. Kung Lao will spin forward instead of stationary.
Torpedo: A move taken from Raiden. Kung Lao flies towards the opponent and pushes them against the corner. Only the MK 2 version of Kung Lao in MK Trilogy can do this move.(MKT)
Dive Kick: Also called the Bullet Kick, Kung Lao dives down from the air and attacks his opponent. This move leaves him extremely vulnerable if blocked. (MKII, MK3, UMK3, MKT, MKG, MK:SM, MK:A, MK 2011)
X-Ray Move - Fist of Shaolin: Kung Lao performs a massive Spin. Upon connecting, he will grab his foe & deliver a hard chop to the neck, near the windpipe. As they are stunned, trying to recover, he then hits the back of their neck with a second chop, shattering their vertebrae. (MK 2011).
Throw: Kung Lao grabs his opponent and Whirlwind Spin several times before slamming them to the ground. (MK 2011)
Throw: Early games have Kung Lao performing a very elaborate flip throw while shouting random gibberish, from the ground (MK2, MKT) & a jumping version (MK3, MKT). If performed too close to the wall, Kung Lao will do a simple overhead toss in MK2 only.
Hat Slice: Perhaps referencing to his infamous MK2 Fatality, Kung Lao chops downward with a very similar-looking overhead command attack. (MK2011)
Body Slice: Kung Lao brings his razor hat down, slicing the opponent vertically in half with a cleanKung Lao performing his Body Slice Fatality on Baraka, in MKII.
Hat Decapitation: Kung Lao throws his hat, which arcs upward suddenly, chopping his enemy's head off. (MKII, MKT, MKG)
Hat Boomerang: Kung Lao tosses his hat at an enemy, decapitating them. The hat then ricochets off the far wall of the screen and doubles back, cutting the enemy in half. A third ricochet slices the enemy off at the knees. (MK3, UMK3, MKT, MKG)
Tornado: Kung Lao executes his Cyclone Spin, and sucks the opponent into it, causing them to explode violently. This was changed to a Multality in Mortal Kombat: Shaolin Monks. (MK3, UMK3, MKT, MK:SM)
Hat Toss: Kung Lao throws his hat at the opponent, which gets lodged in their head. He then stomps on the opponent's stomach to retrieve his hat. In Mortal Kombat: Shaolin Monks, he slams it into the opponent's head and then retrieves it when his opponent is on their knees. (MK:DA, MK:SM)
Mid-Air Slice: Kung Lao kicks the opponent into the air and then amputates his opponent's limbs and head with his hat. (MK:SM)
Arm Cutter: Kung Lao chops off the arms with his hat, and as his opponent attempts to run away, throws it, decapitating them. (MK:SM)

Many Chops: Kung Lao takes off his hat and cuts off each limb one by one. As the opponent falls to the ground, Kung Lao walks over and slams his hat down on the opponent's neck, decapitating them. (MK:SM)
Razor's Edge: Kung Lao kicks his opponent to the ground, then takes off his hat and makes it roll continuously on the ground. He then drags his opponent through the buzzsaw groin first. In MK 2011, Kung Lao lifts up the victim by his/her legs rather than retrieving the hat. (MK:SM, MK 2011)
Hat Trick: Kung Lao throws his hat past his opponent. The hat comes back like a boomerang, decapitating the opponent. Kung Lao quickly catches his hat and vertically slices the opponent's body in half. (MK 2011)

Kung Lao made several appearances in Malibu Comics' MK series. His story is slightly altered, stating he is an exile in Outworld due to the failure of his ancestor, and the fall of his lineage. During the Blood & Thunder series he has a minor participation rescuing a near-death Liu Kang after he was stabbed by Kano. In the Battlewave series, he joins with Kitana, Baraka and Sub-Zero in an attempt to overthrow the Emperor Shao Kahn. During the comics, he shares a very close relation with Kitana, contradicting the games' official story about Liu Kang and Kitana's love relationship.
He was featured in his own one-shot issue from Malibu Comics in the summer of 1995. The comic, entitled Rising Son, showed his struggle against Shang Tsung and his shapeshifting mind tricks, using his friends' forms (Kitana, Baraka and Sub-Zero) as well as his ancestor's form to kill him. It would be the very last issue produced in Malibu's Mortal Kombat series.
Kung Lao was also the centerpiece of the non-canon 1995 Mortal Kombat novel written by Jeff Rovin. However, his description therein completely differed from that of the games; he was depicted as being tall, bald save for a queue of long black hair (similar to Goro), and wearing a long white robe.
Kung Lao appears in the intro of Armageddon, fighting Baraka in mid-air using his sword.
Kung Lao can be seen using his Hat Throw and Teleport Techniques in the intro of Shaolin Monks, fighting Baraka, Goro and Scorpion separately.
Despite being a major character in the Mortal Kombat series, the modern Kung Lao was rarely established in most of the MK media including the two films, the live action MK Conquest tv show, or even the USA cartoon series though there are hints that he would star in the next season of MK Legacy.
Kung Lao's body can be seen in the introduction of Mortal Kombat: Deception, located on the stairs leading to the Soulnado chamber. He is also in Mortal Kombat: Deception's Konquest Mode, where he asks Shujinko to find Kai in Outworld.
In Deadly Alliance, Kung Lao has a joke image of himself having his own infomercial and selling swords for a limited time.
In Deadly Alliance and Armageddon, he and Quan Chi use the same weapon, except Kung Lao uses one sword while Quan Chi fights with two.
Also, in Deadly Alliance, Kung Lao has the same voice actor as Raiden, Hsu Hao, and Mokap.
In the first episode of Mortal Kombat: Conquest, the original Kung Lao is briefly seen wearing the modern-day Kung Lao's attire including his iconic hat prior to defeating Shang Tsung in Mortal Kombat.
The White Lotus Society had meant for Kung Lao to be their champion in Mortal Kombat, but he refuses; only wanting peace and nothing to do with the dangerous and brutal tournament, so they sent Liu Kang instead.
However, Mortal Kombat: Shaolin Monks retconned this, by stating that Liu Kang was chosen over him, and an arrogant and jealous Kung Lao went to the tournament in disguise as a Masked Guard. This was not considered canon, due to Shaolin Monks not being consistent with the series. In Mortal Kombat 2011 he entered in the tournament only to prove to Raiden that he was a worthy warrior, not to be the champion.
Though his Arcade ending in MK 2011 is non-canon, it is interesting that he is referred to as a reincarnation of The Great Kung Lao as well as a descendant. Whether this is true is unknown.
His Fatality in MK 2011, Razor's Edge, shares the same name as his Brutality in MK:SM.
In MK 2011, he seems to be oblivious to the fact that Goro killed his ancestor.
During certain X-Ray Moves, Kung Lao's hat will fall off. However, during certain Fatalities, the hat will stay on Kung Lao's head, even if his head is split in half. The hat will also split in half and remain attached to the halves of Kung Lao's head.
Kung Lao's Unfriendly Rabbit may be a reference to Monty Python and the Holy Grail.
In the opening cutscene of the MK 2011 Story Mode, Kung Lao is seen dead with the skeleton hands of Shinnok's clone wrapped around him, leading many to believe Shinnok's clone killed Kung Lao. Kung Lao's hat is also seen in between the split head of Baraka, leading many to believe Kung Lao killed Baraka.
He was thinted at as downloadable content for MK vs. DCU. It was revealed later on that Quan Chi was the only character actually planned as DLC from the MK side.
In Mortal Kombat: Deadly Alliance, Kung Lao had his costume reversed: his alternate costume (with long hair) as the main costume and the primary costume (with his trademark hat) as the secondary costume.
Early on in MK2011's life, his X-Ray was listed as "Kick Of Shaolin", despite no kick ever taking place during the move. Perhaps it was a typo or in reference to an omitted move. Fixed in later patches.
