"What the hell is that!?"
"That's the end of Halvo Bay...
Damon Baird and Garron Paduk upon seeing Shibboleth

The Shibboleth[1] was a mutated Corpser.[2] A large land-based monster under the control of the Locust Horde, it served as the personal mount of General Karn. Resembling a monstrously-huge spider-like creature, Shibboleth participated in the Horde's campaign against humanity, most notably the destruction of the Republic of Gorasnaya and the attack on Halvo Bay.


Early HistoryEdit

Sometime before the Locust War, Shibboleth damaged its leg and was found by a wandering Karn. Karn saw himself within the beast, alone and forgotten, and decided to construct it a new leg in order for it to walk again. Shibboleth bonded to Karn and became his ever-faithful mount. He was also modified by Ukkon for Karn's use which Ukkon reported to Uzil RAAM shortly after he gained power.[3]

Locust WarEdit

Fall of GorasnayaEdit

Destruction of Halvo BayEdit

When General Karn led the Destruction of Halvo Bay, he rode Shibboleth through the city. Kilo Squad spotted Karn and Shibboleth outside the Museum of Military Glory and Private Garron Paduk identified the two as the ones who were responsible for the destruction of Gorasnaya. Knowing they need to take them down, Cadet Sofia Hendrik suggested using the Lightmass Missile to kill Shibboleth and Karn, but Colonel Ezra Loomis refused. Kilo went against orders and fired the missile at them, having sacrificed Troy to get a target lock. The Lightmass Missile destroyed the museum and killed hundreds of Locust and presumably, Karn and Shibboleth, who were pinning down Omega-Two.

Last Stand and DeathEdit

"Your Boogeyman? Doesn't look so tough."
— Col. Loomis after seeing the Shibboleth for the first time.

Later, during the Locust attack on the Courthouse where Kilo was on trial for using the Lightmass Missile, Karn and Shibboleth revealed themselves to have somehow survived the explosion and destroyed the King Raven helicopter that was about to extract Kilo and Colonel Loomis. Shibboleth and Karn retreated by digging under the ground and making their way to the Plaza for the Tyran Dead just outside the Courthouse. There, under Karn's control, Shibboleth fired its machine guns at the group, but they were disabled. When that failed, Karn tried to take them out with an Incendiary Grenade launcher and retreated when Kilo and Loomis disabled that. After the squad briefly battled Locust reinforcements, Karn and Shibboleth returned and tried to trample the humans as well as launch Digger beasts from Shibboleth's mechanical leg. In response, Kilo destroyed the mechanical leg, forcing Shibboleth to retreat once again. Shibboleth released Nemacysts to attack the humans and after more reinforcements arrive, attacked again with its machine guns. Kilo and Loomis once again disabled the guns and Shibboleth exposed its mouth in a scream from the injury, allowing Kilo and Loomis to concentrate their fire on its mouth and head with the help of nearby King Ravens, despite trying to take them out with fire bolts from its mouth and Karn shooting them with his Boltok Pistol, the combined forces of the COG manage to destroy its mouth, killing Shibboleth. His master just lived a few seconds more than his pet, just as Col. Loomis put a bullet through Karn's dying body.

Shibboleth was a unique creature employed by Locust General Karn as his personal mount in battle. Shibboleth was unique in that it had claws very close to that of an infant Corpser (one of which is a mechanical prosthetic) and with the ability to launch Nemacysts.  Unlike a Corpser, Shibboleth has no appendages on its caterpillar-like thorax, which hangs loosely. Shibboleth was extremely unique in that it appeared to serve the Locust (or at least Karn) of its own free will, rather than being broken and forced into servitude like some other animals. It is unknown if the Shibboleth was unique, or if there were others of its kind.

Behind the ScenesEdit

  • You can purchase a Shibboleth Pet avatar item on the Xbox Live marketplace for 240 Microsoft points.
  • Shibboleth is the final boss of Gears of War: Judgment, succeeding General RAAM, the Lambent Brumak and the Tempest from Gears of War, Gears of War 2 and Gears of War 3 respectively.
  • Its role as a personal mount to a high-ranking member of the Locust Horde is similar to that of the Hydra and the Tempest (who served to Skorge and Myrrah respectively).
