The mysterious and abominable fungus creatures known only as Shoggoth. They're a colonial organism made of a variety of fungal organisms working as one unit, absorbing organic material into their whole to further gain mass and shape themself and gain the abilities of whatever they've assimilated. Despite their base form barely being sapient, those working for Unisys have absorbed an organ known as a "Compassion Core" to trade their raw power for intelligence, so they can use technology.
