A ravenous mutation of female >>HOMO SAPIENS<< similar to the >>FANBOY<< strain. Much like the Fanboy mutation, Fangirls exhibit a phenomenal obsession towards a specific individual, similar to a religious extremist's devotion to a >>DEITY<<. Unlike the Fanboys, which are regarded as particularly inferior to normal humans in every way, Fangirls have been documented to be superior to the average human in terms of cunning, intelligence, strength, speed and agility. These traits are amplified exponentially as the number of adjacent Fangirls increases. While individually these beings are fairly docile, in large numbers Fangirls present a mortal threat to anything, living or otherwise, in the path between the swarm and their target. The highest amount of caution must be excercised when in the vicinity of a swarm as the likelihood of dismemberment increases with closer proximity. In the case of a >>CATACLYSM CLASS INFESTATION<<, incendiary munitions such as >>WHITE PHOSPHORUS<< and/or a >>THERMONUCLEAR WARHEAD<< with a yield exceeding 100 megatons are recommended in swarm dispersal as conventional firearms can only deter a Fangirl temporarily because of the strain's advanced regenerative properties.
To date, all targets of Fangirl swarms have been apprehended by said swarms. Their whereabouts and conditions are currently unknown.

Now the Alliance of Video Game Heroes is fortifying their bases against a possible FANGIRL attack. They are mourning the loss of one of their top-ranking troops. Weapon turrets and missile trucks have been deployed, and security drone production has been boosted by 50%. The base is on constant Yellow Alert, and all recon and solo missions have been cancelled. A last-ditch nuclear weapon has been installed to take the FANGIRLS down with the base.
