From Star Trek’s Borg to Rick and Morty’s Unity: The 10 Strongest Hive Minds In Sci-Fi, Ranked

Hive minds have been a subject of great fascination in science fiction, posing a threat far beyond our imagination. Uniting multiple individuals into a single consciousness raises questions about free will and control.

In movies, TV shows, books, and games, the concept has been pushed to existential limits by placing hive minds in real-world scenarios. Whether it’s space operas, horror, or even a kaiju, this ranked list explores the strongest hive minds in sci-fi history.

10 Geonosian Brain Worms From Star Wars

The Geonosian brain worms were first introduced in Star Wars: The Clone Wars as parasites that infested hosts and linked them into a group mind controlled by the Geonosian queen Karina the Great. The worms were relatively small in scale, but their devious methods of silent takeovers made them a strong hive mind collective that worked in perfect sync.

9 Cordyceps Network From The Last of Us

From the way they looked to the way they sounded, the cordyceps in The Last of Us were genuinely frightening to behold once they took over a host. Acting as a fungal infection that spread through bites and spores, the entire network acted like a real-world fungus. With extended signal systems that could alert each other from large distances, the hive mind zombies relayed information through underground tendrils.

8 Arachnid Brain Bug From Starship Troopers

Starship Troopers gave us a horde of highly intelligent arachnid creatures that were secretly controlled by the Brain Bug. The species later evolved into “godbug,” with a central brain that could absorb knowledge by sucking it from its hosts. Broadcasting through their hive mind collective, information and tactics would be sent across the arachnid forces, making them a formidable machine of war.

7 ⁠ Unity From Rick and Morty

Unity from Rick and Morty is perhaps the most unique entry in this list because of Rick’s love story in the universe. The alien hivemind seizes control of entire populations by “puking” into a host to gain control. Rick has a romance with the entire collective of Unity, who can be any gender or any species that Rick wants, posing moral and ethical questions. The hive mind from Rick and Morty is similar to Pluribus’ storyline.

6 The Thing From The Thing

The Thing is John Carpenter’s magnum opus of cosmic horror, introducing an alien species to the Antarctic. Like other hive minds, this organism absorbs other life-forms and jumps from host to host as perfect imitations. Playing out like a horrific game of Among Us, nobody knows who the alien is while it functions as a stealthy hive mind of body horror.

5 Starro the Conqueror From The Suicide Squad

James Gunn’s The Suicide Squad ended with the Starro kaiju wreaking havoc on a city. The kaiju was a colossal psychic starfish that released countless smaller starfish that latched onto hosts to seize control of their minds, similar to the sequids from Invincible. The infected members were connected to Starro, who dominated cities and planets in DC lore.

4 ⁠The Mind Flayer From Stranger Things

A visit to the Upside Down is enough to make any sane person stay away from the hive mind of the Mind Flayer. Stranger Things introduced the iconic Demogorgons in Season 1, and these monsters were later revealed to share a collective hive consciousness through psychic links and vine networks to the Mind Flayer. Given the shared nature of these nodes, the kids could inflict damage across the web by targeting a single part of it.

3 The Zerg Swarm From StarCraft

The insectoid alien species, the Zerg, are obsessed with assimilating others to evolve their own swarm. StarCraft posed a threat of cosmic proportions by allowing the Zerg to blend their genetics through psionic control that was linked to Queens. This allowed them to be battlefield-ready at all times, immediately responding to threats and adapting to new weapons across space.

2 The Flood From Halo

The Flood is a parasitic hive mind that infects sentient beings by absorbing their knowledge into a massive aggregate called Graveminds. The collective acts as a strategic brain and, with enough biomass, can outthink even advanced civilizations in the galaxy. Superweapons by the Halo Forerunners were needed to contain the extinction-level threat posed by the Flood hive mind.

1 The Borg Collective From Star Trek

The strongest hive mind award easily goes to the Borg, a cybernetic civilization that assimilates individuals into a frighteningly large consciousness. By absorbing their biological and technological distinctions, the Borg became a formidable alien threat numbering in the tens of thousands. In Star Trek lore, they are surpassed only by reality-warping entities.

Here are all the hive minds summarized in a table.

The hive mind concept is largely considered a moral playground for creators to discuss matters of free will, and most recently, it served as the central premise of Vince Gilligan’s Pluribus. Here are commonly asked questions.
