** While the Prequel Era shows both the Republic and the Separatists using ships of various designs, ''Film/ThePhantomMenace'' adheres to the Sinister Geometry-coded villains with the Trade Federation's droid army squaring off against the organic Gungans and the elegant, shapely yellow/silver Naboo starfighters.

* ''VideoGame/Kirby64TheCrystalShards'' had a boss shaped like a giant 20 sided die. It was Miracle Matter, a giant white icosahedron with each side graced with a red eye. Also, the boss of that game's second world was a trio of octahedra called 'Pix.'

* ''The Second Renaissance'' in ''Anime/TheAnimatrix'' series features massive octahedral warbots, floating over the shattered battlefield.

* The cylindrical alien probe from ''Film/{{Star Trek IV|The Voyage Home}}''.

* Most of ''VideoGame/EarthBound'''s late-game alien enemies are rendered on the overworld as floating grey octahedrons. Unlike most enemies, their actual forms in battles look nothing like these overworld sprites; an octahedron could be anything from an alien bounty hunter to a mysterious robot, and you won't know until you're in battle with it. You run into enemies with the same appearance in the final dungeon of ''VideoGame/{{Mother 3}}''. However, this time they actually ''are'' killer octahedrons, rocks called Minerali.

** The Contingency, one of the end-game crises, utilizes ships in the shape of complex three dimensional solids, ranging from stellated polyhedrons to what can be described as Sierpinski octahedrons.

* ''The Second Renaissance'' in ''Anime/TheAnimatrix'' series features massive octahedral warbots, floating over the shattered battlefield.

** The Death Star, the brutal wedge-shaped Star Destroyers, and the hexagonal/spherical TIE fighters are classic examples. As part of the same trope the rebels are more human: the X-wing is closer to a fighter jet, the rebel battleships have curved, organic lines.

* In ''WesternAnimation/{{Home}}'', the Gorg mothership and its drones resemble a bunch of giant spiky pyramids stuck together, while the Boov colony ship is basically a giant sphere.

* Sinister-looking polyhedrons occasionally pop up in ''Webcomic/ABeginnersGuideToTheEndOfTheUniverse'', invariably bringing trouble. For example, the Stone Cube sprouts into a MookMaker [[GrowsOnTrees tree]], while a Stone Tetrahedron transforms into a troublesome EnigmaticMinion. By the time a Stone Dodecahedron pops up, the protagonist has had enough and [[EnergyWeapon lasers]] the heck out of it before it can do something nasty.

* The ships of the Vogon Fleet from the movie of ''Film/TheHitchhikersGuideToTheGalaxy'' are giant rectilinear monoliths (it reflects the Vogon's utter lack of imagination as [[ObstructiveBureaucrat oppressive bureaucrats]]) that demolish the Earth in an eerily quick and efficient fashion. When they're stationed on the surface of the Vogons' home planet, the ships fittingly resemble the nightmare skyscraper-sized pillars from the aforementioned ''Film/{{Brazil}}''.

* The ships of the Vogon Constructor Fleet from the movie of ''Film/TheHitchhikersGuideToTheGalaxy'' were rectilinear. It helped showcase the Vogon's utter lack of imagination.

* ''Film/TheHitchhikersGuideToTheGalaxy2005'': The ships of the Vogon fleet are massive monoliths that demolish the Earth in an eerily quick and efficient fashion. When they're stationed on the surface of the Vogons' home planet, the ships fittingly resemble the nightmare skyscraper-sized pillars from the aforementioned ''Film/{{Brazil}}'', as the Vogons themselves are [[ObstructiveBureaucrat oppressive bureaucrats]].

* In ''WesternAnimation/AllegroNonTroppo'' the ''Bolero'' segment ends on a dark note with civilization taking over, represented as monolithic skyscrapers erupting from the ground. The following segment ''Valse Triste'' follows through by setting up its story in a desolate abandoned apartment that is soon going to be demolished to make way for the expansion of a vast, eerie city composed entirely by identical, white, windowless buildings.

* In ''Film/{{Brazil}}'', Sam's dreams take a dark turn when the bright, idyllic landscape he flies over is suddenly torn by huge, monolithic dark pillars that erupt from the ground and grow rapidly tall separating him from his dream girl. The pillars then overtake everything forming a vast and moody dreamscape that resembles the corridors of the [[ObstructiveBureaucrat Information Retrieval]] building he works at.

* The Infinity Sphere in the ''Leviathans'' DLC for ''VideoGame/{{Stellaris}}'': a jet-black sphere etched with sigils, found in orbit around a black hole. It is one of the eponymous Leviathans, and [[BonusBoss not to be underestimated]].

* The [[http://bobadventures.comicgenesis.com/d/20130806.html "satisfyingly enigmatic'']] [[http://bobadventures.comicgenesis.com/d/20130803.html cone-shaped spaceship]] from ''Webcomic/TheInexplicableAdventuresOfBob''

* The inside of [[EldritchAbomination Reapers]] in ''Franchise/MassEffect'' are said to be this. They are composed of sharp, geometric and compressed shapes, giving the people who enter them a sense of claustrophobia and paranoia. They act as a type of visual layer on top of the Reapers' already insidious power of [[MoreThanMindControl indoctrination.]] They seem to press in on a person, making them feel trapped, disoriented, and powerless, so they more easily lose hope in their willingness to fight the indoctrination.

** The entity Jesse talks to, Polaris, manifests as a spiral pattern, and has the ability to repel the Hiss, whether through protecting Jesse directly or using her as a conduit to banish it.

Summary: if your aliens are cute as Care Bears, omens be fair. [[note]][[BewareTheCuteOnes well, neutral, anyway]][[/note]] [[AddedAlliterativeAppeal Picometer perfect polyhedra]]? Beware.

* Bill Cipher from ''WesternAnimation/GravityFalls'' is a one eyed, triangle shaped EldritchAbomination and probably the most dangerous creature on the show.
