- Parasite (The Hidden)
Okay, so this little guy spends its time hiding out in human bodies, though it’s not content with just surviving peacefully. This little bastard likes to cause as much destruction as it can before its host body can no longer function, at which point it jumps into someone else and starts its rampage all over again. From robbing banks to laying siege to a police station all the way up to attempting to assassinate a presidential candidate, this thing is insatiable in its blood lust.
The main reason I like this little guy so much is basically because it’s just a god damned lunatic. It literally has no other goal than to just kill as many people as it can. Why? Who the hell knows! It’s kind of insane that a little alien slug monster has such a lust for carnage and death. The alien Lawman sent to stop it describes it as a “Thrill killer” so I guess alien psychopaths come in all shapes and sizes.
