Item from Limbus Company by Project Moon
Unkillable entities manifested from human fears and desires through Cogito -- they can only be temporarily suppressed before reverting to an ovate core and hatching again.
Abnormalities were created through Lobotomy Corporation's Cogito experiments -- the materialization of the human subconscious into physical form. They are the source of Enkephalin energy and the basis for E.G.O. extraction. They cannot truly die -- only be temporarily suppressed, after which they revert to an ovate form that will re-hatch. In Limbus Company, Abnormalities serve as boss encounters in the underground Lobotomy Corp branch dungeons. They are distinct from Distortions (which are humans who have been overwhelmed by emotion and can actually be killed) and Peccatula (lesser entities that can exist in multiples). The Sinners must fight through residual Abnormalities to reach the Golden Boughs.
Abnormalities take wildly varied forms reflecting the human fears and desires that spawned them. They range from twisted fairy-tale creatures to abstract horrors to deceptively beautiful entities. Each has a classification code and multiple 'Parts' that can be destroyed or severed in combat. Upon suppression, they revert to an ovate core that will eventually hatch, making them functionally immortal.
