Gekkos are unmanned, autonomous war machines that developed by AT Corp for use in ground combat. They also have a variant called Suicide Gekkos, whose main form of attack is blowing up via a nuclear demolition charge, taking out all around it. 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.

They appear as common enemies in the video games; Metal Gear Solid 4: Guns of the Patriots, and Metal Gear Rising: Revengeance.


In 2014, the Gekkos were mainly deployed by the PMC during Liquid Ocelot's Insurrection. First, they were deployed in the Middle East by the Praying Mantis PMC for heavy weaponry assistance against the town's rebelling miltia. Afterwards, they were sent to South American to assassinate Solid Snake, assist the Pieuvre Armement PMC to wipe out the remaining rebels, capture Doctor Naomi, and kill a recently appearing Cyborg Ninja, who was actually Raiden. Finally, a pair of Gekkos were deployed in an attempt assist the Raven Sword PMC in assassinating an escaping Solid Snake and Big Mama.

A large handful of Gekkos were stationed outside, around, and in Shadow Moses Island, wiping out any hostile personal, specifically the aforementioned Solid Snake. After intercepting the core of the base, Solid Snake was faced with several Suicide Gekkos to fend off while Otacon repaired Metal Gear REX. An army of Gekko units were stationed on the docks of Outer Haven, but were deactivated due to Otacon's/Sunny's FOXALIVE virus.

After the assassination of Liquid Ocelot, Gekkos were still mass produced despite being shut off after the Insurrection, going up to at least the year 2018. There, during the Desperado Incident, Raiden had to fight a now camouflaged Gekko unit, now with the surname Unmanned Gear (usually called UG).


Gekkos, being designed to be a compact Metal Gear, have pairs of artificially created muscle tissue covered legs that contains extreme strength, able to jump a very long distance with them, can crush a human with no effort, and are known for their powerful kicks that can flip a transport truck over. Gekkos can only see heat and visible light, as well as aural sensors so it can sense and hear movement.

Usual Gekkos have a beak mounted machine gun that fire deadly, armor piercing rounds as well as a retractable cable that can be controlled and acts like an appendage. These cables can pick up, examine, and restrain objects. Its domed head is nearly indestructible, but their semi organic legs are not, making these their weakness so that can be tipped over. Another main appearance in its arsenal is a family of hand grenades, but its more unconventional forms of weaponry are anti-tank missiles, M2 Browning machine guns, grenade discharging arrays, and ECM arrays.



  • Gekkos are sometimes nicknamed, the "Lizards".
  • There are three types of Gekkos; Regular Gekkos, Dwarf Gekkos, and Suicide Gekkos.
