This was demonstrated by their first encounter with Venom Snake in Afghanistan, where they were heard yelling "Snake" in a rasped tone.
Despite this, however, they did have a limited capacity for speech. It destroyed most of their cognitive functions, leaving them to effectively become zombies both physically and mentally.
MGSV TPP PARASITE CODE
They received their powers from a species of parasite discovered by Code Talker. The Parasite Unit wore technologically advanced suits that could be used as camouflage to appear as a member of a different organization.
The Parasite Unit in this case had been sent to No Alert's FOB by a rival as revenge. In addition, the Parasite Unit itself eventually resurfaced and proceeded to attack one of the FOBs of an allied Private Force of the Diamond Dogs, No Alert, with their being forced to ask for Diamond Dogs' help in driving out the Parasite Unit for good. Unable to revert the captured Skulls back to their original forms, they are held prisoner aboard the Quarantine Platform on Motherbase. Upon capture, Diamonds proceeded to depower them by extracting the parasites within their bodies, though this did not revert the physical mutations their bodies had undergone when they were infected. Diamond Dogs were eventually able to extract and capture a few of the Skulls while operating in the AO. After succeeding in grounding the helicopter at the Nova Braga Airport, the Skulls moved in to execute the crash survivors, but Venom Snake managed to fend them off and escape with Code Talker.Īfter Skull Face's death, Code Talker assisted in the creation of the Parasite Suit for the Diamond Dogs, a special combat suit that would allow the user access to some of the supernatural abilities of the Skulls using parasites extracted from their bodies. While Code Talker and Snake were en route to Mother Base via helicopter, the Armor Unit tried to prevent them from reaching their destination, taking down Snake's helicopter using a cloud of corrosive metallic archaea. Ultimately, Venom Snake met with Code Talker and the Camouflage Unit could not prevent Snake from extracting him out of the area. Later during Venom Snake's mission to extract Code Talker, the Camouflage Unit attempted to stop him from reaching Code Talker's residence in Lufwa Valley. Discovering Venom Snake's location, they attempted to kill him and prevent his stealing of the cargo, though Snake was able to extract the truck and fend them off.
When Venom Snake embarked on a mission to extract the truck and its contents, the Armor Unit revealed themselves after Snake moved into the truck's vicinity. The Skulls were later redeployed into central Africa to personally escort a convoy of armored vehicles, protecting a transport truck which carried nuclear weapon "yellowcake" and uranium enrichment archaea. They later reappeared during Snake's mission to acquire the Honey Bee at Da Smasei Laman, where they were ordered by Skull Face to kill him, but again failed to do so. Later, after Venom Snake rescued Miller from Da Wialo Kallai, the Mist Unit of the Skulls attempted to kill Miller along with Snake, but ultimately failed as Snake and Miller made their escape via helicopter. Miller implied that Skulls may have spared him and handed him over to the Soviets by accident. Their earliest known activities involved the capture of Kazuhira Miller in early 1984, whom they spared after killing his entire unit and decidedly gave him to the Soviets. Skull Face implemented the parasites alongside additional technology to numerous XOF operatives in order to create the "Parasite Unit", also known as the "Skulls." Certain strains of the parasite would bestow upon the host mysterious abilities if the body accepted the parasite. Sometime before the early 1980s, Skull Face discovered an old Diné man under the moniker Code Talker who had discovered a species of parasite from the remains of The End.
