The Gekko was a large unmanned autonomous fighting vehicle developed by AT Corp for use in ground combat. Officially designated IRVING by the United States Army, Gekko were colloquially called "lizards" after the species of small lizard with a similarly spelled name: gecko. These war machines were created using a combination of technologies used in the production of Metal Gears REX and RAY. However, Gekko were not Metal Gear. Unlike true Metal Gear, Gekko had no nuclear launch capability. Instead, they were more akin to infantry fighting vehicles, with multiple units acting as a coordinated team in support of ground forces.
Physical characteristics
A Gekko had a large mechanical turret-like head whose shape gives the impression of a distinct face and snout. This was connected via a neck to a smaller body at the back of which are two large, hip-like structures. Like the head, the neck, body and hips were mechanical. All were connected via mechanical movable joints. The joint connecting the head to the neck allowed the head to turn 360 degrees.
Attached to the hips were a pair of very strong legs with three-toed clawed feet and a single large claw on each heel. These legs, unlike the head, neck, body and hips, were biological, save for the claw on the heel. The legs were composed of artificially created muscle tissue cloned from the stem cells of ungulate embryos. Gekko walked on their toes. Because each hip was connected to the body via a ball joint, a Gekko's legs had a very large range of motion. For unknown reasons, the central front area of the hips had a warning sign forbidding anyone from trying to strike at this area.
The engine system of the Gekko had a power output of 650HP.
Atop the head and between the hips at the front of the body was a dome-shaped sensor capable of detecting visible light and infra-red, and equipped with night vision and other enhanced imaging abilities, such as the ability to scan through solid objects. A Gekko also had aural sensors, enabling it to detect sound.
Being bio-mechanical, a Gekko had a circulatory system that used blood to nourish its legs. If cut or shot, its legs would bleed. Since they were made of living muscle tissue, the legs produced lactic acid which build up with muscle activity. This acid had to be expelled periodically. Gekko did this via a release of accumulated lactic acid as a yellow-green liquid from an orifice between the hips.
Gekko communicate by lowing like cattle or chirping like cicadas. If shot in the head with sufficiently high caliber ammunition, they would squeal on the bullet's impact. Should they fell over on their backs due to damaged or otherwise incapacitated legs, they would screech like wounded, frightened animals. Catastrophic damage elicited a loud groan before the unit collapses and explodes.
They also acted as carriers for Dwarf Gekko, which were a smaller, spherical, three-armed variant of the Gekko designed specifically to accomplish combat and infiltration situations that regular Gekko couldn't due to their size.
As of 2018, the latest model was the "Block 30" unit. Its artificial muscle contraction rate was increased by 6% and the chassis was made from honeycomb boron-fiber reinforced plastic. It was equiped with a milliwave radar, low-light camera, infrared camera, acousting positioning gear, chemical sniffer and its armed with a .50 calibre machine gun. The Block 30 was utilized by Desperado enforcement.
Abilities
Because of the strength of the legs and feet and the sturdiness of the unit, Gekko were able to run at high speed and leap great distances into the air, enough to clear low-story buildings. They could use their legs as formidable weapons. A Gekko's kick was powerful enough to completely overturn a vehicle as big as a 6x6 transport truck with minimal effort, and could strike a human opponent with such force that his body hit a wall hard enough to shatter it on impact. The claws on their feet and heels, and the range of motion provided by their hip joints, allowed them to move with remarkable agility for such large entities; a Gekko was observed dodging a rocket-propelled grenade round fired at it while executing a lethal counterattack against the shooter. Gekko could climb up into areas it would seem impossible for them to reach. They were able to scrunch down into a surprisingly compact size and enter low-ceilinged areas it would not seem possible for them to enter, provided the area was wide enough for them to fit. A Gekko, for example, was able to drop down through a ceiling into a corridor in the nuclear disposal facility on Shadow Moses Island scrunched down, surprising Solid Snake as he was about to enter the corridor round a corner. It patrolled the corridor back and forth in this position. Despite these abilities, as well as the relative versatility of the mechs compared to other armored mechs, even these abilities had their limits: although they technically could operate within indoor areas, it was demonstrated to be somewhat of a hinderance, and they couldn't operate in tight spaces such as ventilation shafts. Because of these limitations, as well as the Gekko's continuous deployment into urban counterterrorism operations in the height of the war economy, where such places were vital to completing these ops, this led to the development and field-testing of a minature version of the Gekko, called the Dwarf Gekko.
A Gekko possesses a long retractable whip-like appendage that it could use to pick up, examine and manipulate small objects, or to throw small explosives such as grenades. The appendages could also be used to restrain enemies, which included impaling them in the body, as evidenced by what they did with Raiden in South America.
A Gekko's head, body and hips were extremely well armored. No ammunition could penetrate it save very high caliber ammunition such as .50 BMG. It could withstand the impact of rocket-propelled grenades; these only served to turn its attention on the attacker. Some Gekko also possessed anti-missile counter-measures that caused any incoming missile launched at it to veer harmlessly up and away as it neared the unit.
Its legs were not armored, but were tough enough to withstand sustained bursts of machine gun fire before giving out. if only one leg was so injured, the Gekko would drop to one knee but would defend itself by shooting at the attacker with its onboard machine gun. If both legs were so injured, the unit fell over on its back, helpless. But this was only temporary; the damage soon healed and the unit gets back up on its feet. Because of the legs' semi-organic nature, they were also susceptible to tranquilizers. However, they only caused the foot to fall asleep. The head and hips were still active to some extent.
Gekko were completely autonomous and unmanned. A Gekko had an AI that allows it to differentiate enemies from allies and civilians, and, coupled with its speed, agility and ability to compact itself, to tenaciously chase an enemy through multiple levels of a structure and investigate signs of the presence of a hidden enemy, including picking up and examining objects that indicated such a presence, such as a fallen lit cigarette. This AI was somewhat limited in its intelligence, though. A Gekko, for example, could use its enhanced visual sensors to image the contents of a box, but its AI is not smart enough to determine whether or not the contents are in the shape of a human body or not. However, Gekko could, at times, display surprising canniness. On Shadow Moses, for example, a Gekko was able to use an elevator to get up to the first floor of the nuclear warhead storage building from the lower levels. Its AI was also not immune to dizziness, which it could experience if its dome sight was spun around by an enemy. This was best demonstrated during Raiden's fight with the Gekko in South America, where Raiden at one point spun the dome sight of one of the Gekko, causing the Gekko to walk precariously away before stumbling and falling over.
A Gekko would not harm civilians. Should a target be in a group of civilians, a Gekko would not take any action. During the rescue of Dr. Naomi Hunter, for example, Solid Snake was able to run past a Gekko in a market in South America with the unit's sensors fully trained on him, by running in a group of fleeing civilians. The unit did not attack though he passed directly in front of it a few feet away, since civilians would have been harmed.
A Gekko had the ability to go into a low-powered state in which it was scrunched down in a compact size, did not move and appeared to be deactivated. This appearance was false. Its passive sensors remained active. Should any object beyond a certain size approach within their range, or should any loud noise occur, the unit would awaken and rise. On Shadow Moses, for example, two Gekko were in this state on each side of a small canyon. Rats and other small creatures were able to move around near them without waking them. But if Solid Snake or his Metal Gear Mk. III approached one it awoke. If he destroyed one with a very high caliber weapon, the other was immediately awakened by the explosion.
Gekko were, however, exceptionally vulnerable to electric currents. This was best demonstrated at Shadow Moses Island, where a Gekko ended up stepping on a reactivated electrified floor, and ended up paralyzed and screaming before collapsing and then exploding.
When not in use, Gekko could be transported in an inactive state on a transport truck. Their compactness in this state allowed them to be easily loaded and unloaded.
Weaponry
The Gekko's deadliest weapons were its powerful legs. A Gekko could easily kick over a large, heavy vehicle such as a deuce-and-a-half. During a conflict in a Middle Eastern city, one was seen to kick over a large transport truck onto a group of insurgents who had taken cover behind it, crushing them. Gekko were known to execute a devastating sweeping roundhouse kick against enemies within range of their legs. This kick almost invariably ended the life of any enemy it strikes. Gekko also were able to kill with their legs by jumping and landing on enemies, stamping on them, grabbing them with their toes and slamming them into the ground with lethal force, and kicking them in the manner that a soccer player kicks a football. Additionally, a Gekko could scrunch down with its head lowered, direct the top of it at an enemy and run at the enemy like a bull, killing him, or in the case of the enemy being a cyborg, seriously injuring him with the impact.
A Gekko armed with two .50 heavy machine guns (left), and a Suicide Gekko (right).
Apart from its legs, Gekko were capable of carrying a number of onboard weapons. With regard to such weapons, Gekko were highly modular. All Gekko carried an internally mounted machine gun near the snout. Gekko were also known to carry a pair of M2 Browning .50 caliber heavy machine guns, tube launchers for anti-tank missiles, or an array of grenade launchers on the back of the head.
Gekko also carried grenades which they lob into out-of-reach areas with their retractable manipulators to kill or flush out enemies.
Besides possessing the above-listed offensive measures, Gekko also were equipped with defensive systems. The most notable of these is its anti-missile counter-measures that directed missiles away from it.
A variant known as the "Suicide Gekko" carried a nuclear demolition charge in their heads. These Gekko possessed no onboard weapons apart from the standard internal mounted machine gun. Their function was to get close to a target and detonate their charges, destroying themselves and the target. However, their effectiveness could be limited, as they could be destroyed by very high caliber weapon fire before they get within effective lethal blast range. Even if they got within range, their bombs emitted an audible countdown as they arm, during which time they were completely immobile and thus fully vulnerable to attack. However, enough of them converging on a target at once could still ensure the target's destruction, since there had to be enough defenders to destroy them all before they arm and detonate. Otherwise, enough could still successfully arm and detonate while others are destroyed before they can do so.
History
Guns of the Patriots Incident
- See also: Liquid Sun, Solid Sun, Third Sun, Twin Suns, Old Sun, and Naked Sin/Naked Son
A Gekko searching a destroyed house, circa 2014.
In 2014, Gekko were used extensively by the PMC forces under Liquid Ocelot.
Several Gekko were deployed in the Middle East to eliminate a local militia. During the encounter, two Gekko encountered Old Snake, who managed to elude them with his OctoCamo.
A Gekko deployed to South America.
Many Gekko were deployed in South America and killed several of the local rebels, and tried to eliminate Snake in order to recapture Naomi. During their search, they also attacked a marketplace. The Gekko then encountered and attacked Raiden (the third Cyborg Ninja), who countered by slicing and destroying several units.
At least two Gekko were deployed in Eastern Europe to eliminate Snake along with Big Mama and the Paradise Lost Army.
Two Suicide Gekkos get ready to blow up Metal Gear REX.
Several of the Gekko units were also deployed to Shadow Moses Island in order to prevent Snake from reaching Metal Gear REX. In addition, Suicide Gekko were deployed to blow up the supply route building on Shadow Moses Island, after Liquid Ocelot retrieved REX's rail gun. They arrived just after Old Snake defeated Vamp, and just as several units were about to self-destruct, Raiden arrived and saved Snake. While Raiden and Vamp engaged in knife combat for their final showdown on top of REX, Snake used his rail gun to destroy the Suicide Gekko that were either attacking or arming themselves for self-destruction. After Raiden's victory over Vamp, Otacon (via the Metal Gear Mk. III) used the reactivated REX's missiles to destroy the oncoming Suicide Gekko. After Naomi's death, Snake (with Otacon's directional advice) used REX to escape the facility while Raiden cut a path for Snake and REX. While Snake and REX were able to get away, the combinated blasts from the Suicide Gekkos caused the building to fall on Raiden.
Finally, several Gekko units were deployed within Outer Haven but were later deactivated when Snake and Otacon uploaded FOXALIVE, destroying the repaired GW AI, the SOP system, and the other AIs (TJ, TR, AL, and the master AI, JD).
World Marshal Incident

Raiden forcing a Gekko UG down.
Despite the destruction of the SOP system via FOXALIVE, Gekko were still mass-produced, being completely unmanned. Several Gekko, named Gekko UG (standing for Unmanned Gear),[2] were later utilized by Desperado Enforcement LLC as well as their ally, World Marshal in the events of 2018, also containing MCFC electrolyte cores. They were somewhat obsolete. During a training session, Raiden, after accessing a Desperado-related computer terminal via an access pass, inadvertently lured a Gekko UG over to his area, forcing him to take it out alongside enemy reinforcements.[3] During this time, it also came in three different camo colors: One was primarily a green camo pattern; another was an urban-style camo pattern; and the last was colored in black and red patterns derived from Desperado.
Behind the scenes
Game design
The term "Gekkō" comes from 月光, the Japanese word meaning "moonlight," while the U.S. codename "IRVING" stems from the American codename for the Nakajima J1N "Gekko" twin-engine night fighter aircraft from WWII. During an interview, Hideo Kojima stated that the Gekko were not the titular Metal Gear of Metal Gear Solid 4: Guns of the Patriots, stating that they are more like a jeep or a tank compared to the actual Metal Gear.[4]

The weapons mounting of a Gekko is similar, but not identical to, the M151 Remote Weapon Station used by real life armored vehicles. It is unclear how a Gekko's heavy weapons are restocked, since it has no obvious capacity for reloading its own weapons in the field; presumably they must withdraw once the fixed armament is depleted, though in the context of the game they have infinite ammunition. Though they are capable of carrying Dwarf Gekko on the sides of their heads, as seen in the game's cutscenes, this configuration is never encountered during actual gameplay.
Some of the models have various letters and numbers on them, hinting that the various Gekko were placed into various divisions within Outer Heaven. in addition the color scheme of a gekko differs depending on which PMC is encountered. However, with the exception of Metal Gear Rising: Revengeance, these changes are mostly unnoticeable.
Trailer appearances
In a pre-release trailer for Metal Gear Solid 4, some Gekko managed to wipe out the Middle Eastern militiamen in Ground Zero. Afterwards, they also released a greenish-yellow fluid (later confirmed to be lactic acid). In addition, within the Red Zone, they also were marching with a platoon of Strykers belonging to Praying Mantis, resulting in Snake (who was spying on them for reconnaissance) almost being spotted by one.[5] Although most of these weren't shown in the game itself, the former was nonetheless implied to have happened off-screen with Snake being pursued by Gekko early in Act 1.
Gekko were also seen in the trailer for Metal Gear Rising.
Super Smash Bros. Brawl
A Gekko, as featured in Super Smash Bros. Brawl.
The Gekko is one of the three mecha, along with Metal Gear REX and Metal Gear RAY to appear in the Shadow Moses Island Stage in Super Smash Bros. Brawl. Also, due to the fact that Metal Gear Solid 4 was released after Super Smash Bros. Brawl, this technically marks the Gekko's debut game.
It should be noted that the Gekko seen is unusually large.
Completing All-Star Mode with ten characters will unlock a Gekko trophy with the following description:
A Metal Gear with a pair of animal-like legs. Gekko are mass-produced weapons used in military combat. Its distinctive legs allow Gekko to move at high speed, jump incredible distances, and even cling to walls, giving it unprecedented mobility. Other noteworthy features of this model include prehensile tentacles strong enough to pick up soldiers and its signature deafening roar.
Note that it incorrectly labels it as a "Metal Gear" and there is no "roar" (unless you count the mooing).
Metal Gear Solid 4
Gekko's sight.
Heavily armored and highly agile, Gekko are difficult to deal with unless armed with a sufficiently powerful weapon, such as the M82A2 .50 caliber BMG anti-material sniper rifle or the rail gun. Their roundhouse kick causes significant damage even at the game's lowest difficulty; at higher difficulties it is almost certain to cause death. They lob hand grenades if Snake retreats into an out of reach area, fire at him with their onboard weapons and run at him with their bull-like charge. Missiles from portable missile launchers are usually deflected by a Gekko's anti-missile counter-measures.
Gekko in the market.
However, they do have known weaknesses. The first is their legs. Though very strong, they are biological and therefore are vulnerable to gunfire, albeit only prolonged bursts, and are also vulnerable to tranquilizer darts from the MK 22 or Mosin Nagant. Enough bullets in one leg will only bring a Gekko down to one knee; it will defend itself using its onboard weapons. Both legs must be shot with sustained gunfire to make a Gekko fall helpless on its back. Tranquilizer darts to the legs will also bring a Gekko to this state. However, this does not last long. The effect soon wears off or the injury from the bullets soon heals, and the unit rises to its feet.
Two Suicide Gekko with nuclear demolition charges
A second weakness is the sensor dome on the head. If this is destroyed, the Gekko explodes. It is less armored than the rest of the head and is therefore vulnerable to gunfire, though it requires a very long, sustained burst to penetrate the armor. Normally it is very difficult to target this sensor given the length of time needed to penetrate the dome's armor, and Snake has to stand still long enough to aim and fire at it, leaving him open to counter-attack. However, if the Gekko were first brought down helpless on its back, then Snake could safely stand still, target the dome and shoot it long enough to destroy it, though the player must take care to stand out of range of the ensuing explosion.
A third weakness is the fact that a Gekko's armor can be easily penetrated by ammunition of large enough caliber, such as from the aforementioned M82A2 sniper rifle or rail gun. One fully charged shot from the rail gun to any part of a Gekko's head will destroy the unit. The player will hear the unit's loud groan due to catastrophic damage, after which it collapses and explodes. A maximum of two shots from the M82A2 to the head will have the same effect. The first shot makes the Gekko wobble and squeal. If it is firing at Snake when the shot hits, its shooting stops. The second shot elicits the same reaction before the groan, collapse and explosion. If first shot is well placed, the second one becomes unneeded.
When fighting the Suicide Gekko in REX's hangar during the Twin Suns act, it is recommended that the M82A2 be used instead of the rail gun, as the M82A2, as, unlike the rail gun, it does not need to be charged for a "killing" shot, eliminating the time Snake is defenseless, during which the Gekko can approach and converge.
The Suicide Gekko's warning voice that verbalizes the self-destruct countdown were recorded by Kris Zimmerman, who served as the English voice director for Metal Gear Solid 4.
Metal Gear Rising: Revengeance
The Gekko made a reappearance in Metal Gear Rising. Their attack patterns are largely the same as in Metal Gear Solid 4, although they don't do as much damage in this game as before.
Metal Gear Solid V: Ground Zeroes
Although they don't appear in the game itself, they can be built in the Mother Base game on the app on iPhone and Android devices as an AFV-type. They require a certain Total of either KO's, Tranqs, or Hold Ups to unlock.
Other appearances
The Gekko appeared in metalgearsolid.com's Versus Battle page, where they fought against Metal Gear ZEKE.
