!Examples:

* The 1997 psychological horror film ''{{Cube}}''. The protagonists are trapped in a grid of cubic rooms filled with {{deathtrap}}s.
* In the sequel ''Hypercube'', the hypercube ''is'' the deathtrap. And has this weird tesselation thing at one point that does strange things to reality... as well as dicing up one of the characters.

* According to some versions of [[MarvelComics Marvel]] canon, the ''[[TwoThousandAndOneASpaceOdyssey 2001]]'' Monoliths are tools used by the [[SufficientlyAdvancedAliens Celestials.]] This is because Machine Man first appeared in JackKirby's ''2001'' tie-in comic, and later stories {{retcon}}ned the Monolith in that story to have been a Celestial gizmo. Whether this makes all the Monoliths' ''other'' appearances in the ''2001'' comic part of official Marvel canon (which would mean the Celestials ''are'' the never-seen ''2001'' aliens) is up for fan speculation.

* In ABC Family's made-for-TV miniseries version of ''{{Fallen}}'', hell includes an endless staircase. The simplest MCEscher staircase illusion.

* Considered a DiscreditedTrope at the SCPFoundation, to the point that one [[http://www.scp-wiki.net/scp-5308-j joke SCP]] includes a granite cube which has been sequestered simply for looking "dangerously Platonic".

Summary: if your aliens are cute as Care Bears, omens be fair. [[AddedAlliterativeAppeal Picometer perfect polyhedrons]]? Beware.

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

* The murderous dividing sphere from Tool's video for their song ''Parabol/Parabola''.
* Gary Numan is awfully distrustful of the glowing pyramid on the cover of ''The Pleasure Principle''.

* In ''ShinMegamiTenseiNocturne'', after the apocalypse, there's suddenly a number of bizarre structures sprouting out of the ground everywhere. They don't seem to be built by human hands at all; there's no furniture in them, they're too smooth and blocky, and have TronLines prominently throughout them.
* In ''DevilSurvivor2'', while the first seven Septentriones are quite unorthodox when it comes to shape, the final Septentrione takes the form of a hypercube encased in a wire frame.

* CPU from ''VideoGame/FinalFantasyIV''
* Ozma from ''VideoGame/FinalFantasyIX''

* The Fighting Polygon Team from ''SuperSmashBrosMelee'': They're not regular shapes, but they are polyhedra, and true polyhedra are generally unnatural.

* The shining trapezohedron from Creator/HPLovecraft's story ''Haunter in the Dark''. Gazing into this alien artefact will grant you visions from beyond our world, but also summons the titular monster, an avatar of the Crawling Chaos Nyarlathotep, to kill or possess you. [[hottip:*:A [[http://en.wikipedia.org/wiki/Trapezohedron trapezonhedron]] is a prism with kite-shaped sides. A ten-sided die is an example.]]

->''The silver sphere is about twice the size of a billiard ball. It has a couple of very sharp hooks built into it. It flies through the air, attaches itself to your forehead, and digs in. Then [[ThisIsADrill a drill comes out]] and pierces your skull right above the bridge of your nose, while blood spurts out the other end. [[MajorInjuryUnderreaction I hate it when that happens]].''

The lack of visual cues is another source of fear. A giant cube in space does not look like a spaceship; it could be ''anything''. It could be a massive bomb, or a toy, or a probe. Consider the monolith from ''[[TwoThousandAndOneASpaceOdyssey 2001: A Space Odyssey]]'': it is the ultimate unknown.

* ''StarWars'':

* The Omnidroid from ''WesternAnimation/TheIncredibles''.
* The MCP from ''{{Tron}}''
* The monolith(s) from ''[[TwoThousandAndOneASpaceOdyssey 2001: A Space Odyssey]]'': sinister in appearance, and utterly unknown. And exactly 1:4:9 [[spoiler: ad infinitum]].

* ''HellboundHellraiserII, introduces us to Leviathan, the Satan-alike ruler of the Hell dimension. It is portrayed as a giant geometric shape resembling a three-dimensional lozenge that sits at the center of the hell-labyrinth, rotating and emitting a lighthouse beam of pain and evil visions.

[[folder:Live Action TV]]

* The Omnidroid series from ''WesternAnimation/TheIncredibles''. Versions 8 through 10 are both black spheres with retractable CombatTentacles.

* ''VideoGame/{{X}}-Universe'': Where {{Space Fighter}}s used by the other factions look airplane-like, [[InscrutableAliens Khaak]] fighters are sets of tetrahedrons in various combinations ([[http://eng.x3tc.ru/screenshot/ship.php?NjY3NzAwOTE fighter]], [[http://eng.x3tc.ru/screenshot/ship.php?NjcwNDQ2Mjc interceptor]], [[http://eng.x3tc.ru/screenshot/ship.php?NjczMTkxNjM scout]]). Their space stations are clusters of octahedrons on sticks, and their capital ships have spider-like arms around a spherical core. Then there's their [[http://eng.x3tc.ru/screenshot/ship.php?Njc4NjgyMzU stationary defense platforms]].

** You run into enemies with the same appearance in the final dungeon of ''{{Mother 3}}''. However, this time they actually ''are'' killer octahedrons.

* ''{{Kirby 64}}'': The Crystal Shards 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 octohedra called 'Pix.'

* The Rubik Snake built by the malevolent AI in DemonSeed.
