Domain Holder

"You don't get it. I built this place. Down here I make the rules. Down here I make the threats. Down here... I'm God."
Trainman, The Matrix Revolutions

Those with this kind of power have their own little domain - a Pocket Dimension, a Mental World, a section of Cyber Space, or a ritually established area overlapping the normal world - where they have editing rights over the laws of reality.

Often used in manga/anime context, to give the overpowered main character a challenge they CAN'T solve with their fists, since the first rule such a Domain Holder usually implements is "Violence doesn't work here, sucker!". There seems to be trade-offs involved in this case, since often, one of the rules is that the Domain Holder is required to fully explain the Rules to his "guests".

Subtrope (and most extreme form) of Home Field Advantage. Compare Field Power Effect and Place of Power. For large Pocket Dimensions, this may make the character a Dimension Lord. If the character has this power over dreams, it makes them a Dream Weaver. If the character's health is linked to that of the Pocket Dimension, they are a Fisher King. An already omnipotent being may be Even More Omnipotent in its home Domain.

     Anime & Manga 
  • YuYu Hakusho: Some characters can establish their own rules in a defined volume of space.
  • Hunter Hunter had similar Pocket Dimensions.
  • In Big Order, the protagonist can do this, imposing his rules on any area he has previously walked on.
  • Beelzebub: Chapter 135 introduces a character who can do this in his 'gameroom', causing all damage dished out inside to rebound on the attacker. To get past his gameroom, they need to solve a series of puzzles, including sudoku.
  • In Dragon Ball Z, Babidi's base can simulate various environments and his henchmen use it to their advantage (although it fails spectacularly when a Heavy Worlder henchman tries increased gravity against Vegeta, who regularly trains in increased gravity.)
  • In Bleach, Yukio Hans Vorarlberna could put people inside video games, where he could control everything, including gravity and time.
  • In One Piece, Trafalgar Law ate the Op-Op (Ope Ope) Fruit, allowing him to create spheres of blue energy within which he has absolute control over everything that goes on inside.

     Comic Books 
  • The page image depicts the title character of Neil Gaiman's The Sandman in the Dreaming, exercising this ability over a demon that had just devoured him. The Dreaming is a place where dream-logic rules anyway: any insidious trap or unstoppable attack is subject to Dream's Retcon or may simply not apply to Dream. No matter how little sense it would make.
    • The domains of Destiny, Death, Desire, and Despair are all implied to work this way as well. It's one of the reasons why they're very uncomfortable with setting foot in each others' homes. Delirium's domain is an even less attractive destination, since by her nature even she isn't in control there.

     Fan Fiction 

  • In The Matrix Revolutions, the Train Man has a small Matrix of his own, a train station used to smuggle renegade programs from the machine world into the Matrix. While inside it, he is basically omnipotent and can even curb-stomp Neo.

  • Practitioners in Pact can claim a portion of territory as a demesne, allowing them to be this trope within its boundaries. Johannes Lillegard, a particularly powerful one, has managed, through trickery and great will, to secure one in the commercial area of the large town of Jacob's Bell, allowing him to distort the architecture so that nobody leaves if he does not wish it, and to prey upon those that inadvertently pass through it.

     Live Action TV 
  • In Season 4 of Fringe, William Bell is trying to create his own Domain.

     Tabletop Games 
  • In Nobilis first and second editions, Nobles with the Realm attribute can shape the reality of their Chancel. In 3e, they can get a similar effect by taking "things of the Chancel" as a Domain.
  • It varies by edition and setting, but in general the gods of the various Dungeons & Dragons worlds have this privilege within their Place of Power (which could be of virtually any size.) Whether or not they have 'stats' elsewhere, it's not healthy for your 75th level archmage to decide he can simply kill one and take its place.
    • Several of the darklords of Ravenloft have the power to control weather, wildlife, and other natural forces within their domains, and a few of them (Easan, Davion) can actually manipulate the fabric of their realms' reality.
    • The gods of the Scarred Lands setting each have their own personal plane of existence where they can do pretty much anything. They never travel personally to Scarn, instead sending an avatar to take care of any business.
    • The Planescape setting is dominated by Sigil, a city under the total (though rarely exercised) control of the Lady of Pain. She has very few rules, but violators will suffer the consequences.

    Video Games 
  • In Saints Row: The Third, Matt Miller, emo-goth-cyberpunk master hacker and boss of his own emo-goth-cyberpunk gang, the Deckers, meets the player in a duel which takes place inside the Deckers' usernet, which is actually a TRON-eque cyberspace. While you advance through the virtual reality, Miller is changing laws of physics to slow your advance and mocking you with quotes of how he controls the very fabric of this world.
  • A staple in the Dragon Age series, where the Spirit World of Fade basically responds to any powerful magical being (whether a mortal mage or a demon), allowing them to shape huge domains around them over time and define their rules arbitrarily.
  • Mankar Camoran has one of these in The Elderscrolls IV Oblivion called Paradise. It is anything but.

    Visual Novels 
  • In the Nasuverse, The Marble Phantasm and Reality Marble are basically Pocket Dimensions which allow you to bend the laws of physics and magic, with the specifics varying for each case.

    Western Animation 
  • In Teen Titans, Mumbo the magician has a small Pocket Dimension inside his hat, in which he has total control of reality. He also seems to use it as a source for many of his summoning spells, implying he can "leak" its contents into the real world.
