Biological, technological or in between these alien adversaries come in all shapes and sizes. They have one common goal: the defeat and downfall of humanity.One thing a lot of these species seem to have in common is a hive-like social structure or mentality that often leads to their downfall.
So far luck and the stubborn refusal to give in to defeat has saved us from certain doom at the hands, claws, tentacles and alien technology devised to bring about humanity’s demise, but how long will it last?
From our galaxy and beyond we have collected here the universes most likely suspects in a science fiction roundup of bad intentions.
The Daleks (Dr.Who): The Daleks are merciless and pitiless cyborg aliens, demanding total conformity, bent on conquest of the universe and the extermination of what they see as inferior races. Their catchphrase, “Exterminate!”, is a well-recognised reference in British popular culture. The Dalek are organic beings encased in a technological shell. Their appearance is reminiscent of what might result from an explosion in a hardware store.
The Goa’uld (Stargate SG-1): This evil snake-like, symbiotic parasitic species embeds itself in a human “host” and takes control of the host’s mind and body. Easily recognizable by their glowing eyes, they have a tendency to be drama queens given to cosplay coupled with megalomaniacal ambitions. While they do not possess much in the way of technological creativity, they are adept at stealing and using technology they find. Warlike and overly ambitious they often fight among themselves and misuse their power to make humans their slaves.
The Dominion (Star Trek Deep Space 9): An alliance of alien races led by a conquering species of shapeshifting beings called the Founders from across the galaxy. They are considered gods by their genetically engineered helpers and warriors the Vorta and the Jem’Hadar. They are intelligent, technologically advanced and capable of taking on the appearance of anyone or anything which gives them the upper hand in most situations.
The Wraith (Stargate Atlantis): This once human predatory species is capable of sucking the life force out of beings they encounter with the touch of their hand. These vampire-like creatures are a formidable foe. Highly intelligent and technologically advanced they also possess great physical strength and an insatiable hunger that drives their insect-like social structure to keep seeking new sources of food. They see and treat human beings like cattle.
The Borg (Star Trek The Next Generation): This race of predominantly humanoid and aggressive cyborgs formed of multiple conquered alien species, including humans, are a threat to any species they encounter. The utterance of their catchphrase, “Resistance is futile” marks one of modern science fiction’s most iconic and memorable moments when Q introduces the hive-minded species to the crew of the Enterprise. It was the beginning of a long relationship that changed everything. A more or less scavenger species the Borg travel through space assimilating and adapting everything they encounter and make it their own while decimating the species and cultures left in their wake.
Replicators (Stargate SG-1): The Replicators are aggressive, antagonistic self-replicating machines that are driven to replicate by consuming both alloys and technologies of the most nearby most advanced civilization and constructing themselves and their progeny accordingly. These Replicators are as relentless as a swarm of locusts from the old testament and just as destructive. They are incredibly difficult to destroy and multiply faster than the insects they usually resemble. They are a remarkably formidable foe.
