SCP-772, or "Giant Parasitoid Wasps", is an upcoming SCP in SCP: Unity that will be added in an as of yet unannounced update.
SCP-772 is a wasp of unknown species, superficially resembling members of the Megarhyssa genus. A mature adult is typically 60 cm in length, from head to abdomen, excluding antennae and ovipositor. This barbed ovipositor, reaching a length of up to 70 cm, is used to penetrate its host and deposit anywhere from 5 to 20 eggs. Eggs are typically 6 cm long and 2.5 cm in diameter. SCP-772 is meticulous and almost surgical during oviposition: it makes an incision no longer than 3 cm, and the host is paralysed and/or comatose for several hours until the wound can heal sufficiently. Injected along with the eggs is a polydnavirus uniquely adapted to suppress the immune system of mammals, analogous to the smaller parasitoid wasps which do the same to their caterpillar hosts.
Female specimens of SCP-772 pose a significant safety hazard, as the ovipositor is extremely sharp and manoeuvrable. When threatened, females will use this organ as a weapon and stab the offender repeatedly. While these wounds are not always fatal, they have been reported to be acutely painful, and cases of bone penetration have been documented. Although caution should be exercised around all specimens of SCP-772, males lack the ovipositor which serves as the female’s weapon and method of host infiltration.
Females are capable of reproducing asexually via thelytokous parthenogenesis and will do so in the absence of males. SCP-772 requires a warm, dark, nutrient-rich cavity in which to lay its eggs. It habitually deposits eggs in the abdominal subcutaneous fat of large mammals, but has been known to utilise subcutaneous fat in other regions, including the shoulder, back, hip, thigh, and [DATA EXPUNGED]. SCP-772 eggs have an incubation period of 4 to 12 days, and length of incubation period is speculated to share an inversely proportional relationship with levels of host stress hormone. Upon hatching, SCP-772 larvae begin their consumption of host tissue, gradually working their way into the depths of the host's body. The larvae may be easily mistaken for abscesses/tumors, but as SCP-772 progresses away from the hypodermis, it appears to the observer that said abscesses/tumors are diminishing of their own accord.
SCP-772 is not currently in-game
