Playing With / Thin Dimensional Barrier

Go To

Basic Trope: Locations where the barrier between worlds is weaker.

  • Straight: The Reality Nexus is an area in upper Troperia, where people can slip into Aireport with ease.
  • Exaggerated: The Multiverse Crater is an entire country that has numerous different universes leaking into it.
  • Downplayed: The Dimension Door is an area that's merely easier to pass through, with much effort still needing to be spent to 'open' it.
  • Justified:
      Advertisement:
    • Troperia was originally the remnants of a shattered universe, and thus despite its seeming stability has plenty of metaphysical weak areas left over.
    • The Reality Nexus is a natural phenomenon in magic using universes, basically being erosion caused by its usage.
  • Inverted: The Spatial Lock is a device that strengthens the barrier between worlds, making it harder to move about.
  • Subverted:
    • Bob claims that the Dimension Doors he opens are natural weak spots, but in actuality he's a natural universe hopper.
    • Emperor Evulz boasts to have a multiversal empire, yet the thin 'doorways' are actually just him using illusions to mislead them.
  • Double Subverted:
    • ...However it turns out he can't open gateways if the dimensional barrier is too strong, meaning he's tearing up the weaker areas anyways.
    • ...Illusions based on real universes he's been to, with his powers acquired from passing through the weak dimensional entryways.
  • Advertisement:
  • Parodied: The Parodion Cloud is a, well, cloud that leads into another universe- Thus it requires great effort to get there at all, and being a cloud means nobody has successfully gotten through to the other universe anyways.
  • Zigzagged: ???
  • Averted: There are simply no 'thin walls', if only in appearance due to nobody knowing how to cause and/or use them anyways.
  • Enforced: "We need to crossover Troperion High and My Steampunk Romance, so... Let's say there's a reality hole or something, nobody can disprove it anyways."
  • Lampshaded: "Wait, how did this even happen? Is this like an old door where the hinges have been broken?"
  • Invoked: Bob, desperate for new adventures, deliberately works away at the stability of reality so he can explore a new one.
  • Exploited: Bob, unable to defeat an Elder Thing, instead lures it through a weak dimensional wall so he can trap it there by sealing the instability.
  • Defied:
      Advertisement:
    • Having realized that poked holes in the multiversal membrane would be bad, The Creator makes sure that nothing can get in or out by accident.
    • The Kingdom of Troperia makes it their duty to seal off any and all dimensional holes, to prevent an invasion.
  • Discussed: "You know, given all the time travel and teleportation going on, how has that not caused metaphysical problems?" "Like what, some kind of thin dimensional wall? Could be the only reason they work is because they're using natural weak areas."
  • Conversed: "Look, I love a good crossover or freaky otherworld, but shows really shouldn't use 'natural thinness' as an excuse." "I actually like the idea, since it justifies crossovers being rare and why people shouldn't be making otherworlds their new vacation spot- Pop goes the universe."
  • Implied: Though there's never any mentions of 'dimensional weakness', the areas used to move between worlds never change and the gateways used are always consistently the same- Thus no instance of the Aireport gate in Troperia being used to directly access the Celestial Realm.
  • Deconstructed: The fact there's a 'natural' weak area between worlds means people and things regularly get lost in between, let alone that the two universes are leaking into each other- The barrier being there specifically to keep them separate, much like cell walls in a body.
  • Reconstructed: The natural weak areas in the universe are more akin to blood vessels than a wound, usually only transporting specific substances across the interconnected chain of universes. Thus, forcing your way through doesn't cause any serious issues.
  • Played For Laughs: Bob, having heard tales of the 'legendary treasures' behind the Dimension Door, manages to finally open it- And instead finds only an infinite void and a sign saying "Feel pretty stupid now huh?"
  • Played For Drama: With the Reality Nexus existing at all, Troperia and Aireport are at mutual risk of destruction- The two universes horribly clashing together, producing all kinds of anomalous effects that make life harder and harder until survival is outright impossible.


Hey look, I wonder where this Thin Dimensional Barrier leads!
