Parasites
The antagonists of the series. The Parasites are creatures of unknown origin which start off as worm-like creatures that instinctively enter the body of the nearest life form and travel to the brain to completely assimilate it while destroying the host's identity in the process. Thereafter, using the vital organs of the host bodies to survive, the Parasites are instinctually driven to kill all humans as well as Parasites with failed host bodies.Upon assuming hosts, the parasites hunted humans at random with little to no coordination among each other. This led to a series of widespread mass-killings which were coined the "mincemeat murders" by the public. As their intelligence and familiarity with their environment grew, the parasites became more cautious in their feeding and eventually formed groups for safety in numbers.
After assimilating their host, Parasites exhibit a variety of abilities that make them dangerous adversaries. The immediate area around their entry site is morphed into a versatile "parasite tissue" which can take a variety of offensive and defensive forms. Additionally, a parasite that successfully takes over a host's brain can then maximize the physical potential of the host's body. Furthermore, though their thought process is coldly rational and almost devoid of anything resembling human emotion, many parasites display intellectual capabilities far in excess of the average human. Depending on their environment, they are capable of learning skills that would take a normal person years to develop over an extremely short period of time. Migi, for example, mastered Japanese after one night of reading books on the subject. Likewise, the überparasite, Gotou, becomes a skilled pianist less than a year after taking on a host body.
Despite their strong instincts, it is possible for parasites to ignore or outgrow their desire to eat humans, and despite this apparent lack of humanity, they can instinctively recognize others of their species by the signal they all emit and regard them as allies rather than competition. Even completely inhuman parasites are willing to work together for a broad range of reasons. By the end of the series, the surviving Parasites have either gone into hiding or have largely assimilated themselves in human society.
