Realm Exclusive Effect

Everything About Fiction You Never Wanted to Know.
Dark World, here we come!

The Realm Exclusive Effect is a phenomenon where a character's powers, magic, appearance, and other attributes change when going from one world or another. A common example is an average person finds themself in another world where they may have superpowers or an item that can grant them one. After being sent back to the real world, the person would have no powers. However, the nature of the other world would have an empowering effect on people or certain items. Characters can use Phantom Zones in a world where their powers don't work, but this is temporary. This trope involves different worlds that characters can access through teleportation or portals. In the case of being Trapped in Another World, characters may become normal when they find a way back home; well, if they even want to go home. Other attributes can change involving this effect, such as appearance, tangibility, mentality, etc.

The purpose is to create contrast between the two worlds, making a more interesting dynamic for the audience. There are more things to think about when a character's powers can only work in one realm, developing the world.

Heavyworlder is a subtrope more common in Sci-Fi. See also HAD to Be Sharp for adaptations or training forced by harsh environment (natural or unnatural) on its inhabitants.

A staple trope of the Portal Fantasy sub-genre. Contrast Normal Fish in a Tiny Pond, where an average character's abilities don't change due to the transfer, but are regarded as stronger in the new world nevertheless due to its inferiority compared to the character's native realm.

Examples of Realm Exclusive Effect include:

  • El-Hazard: The Magnificent World, one of the earlier Isekai licensed for release in North America, has four people gain powers when they are transported from Earth to El-Hazard. (Which powers they get depends on which continuity they are in.) At the end, at least one of the people returns to Earth.

  • MÄR has people from Earth teleported to MÄR-Heaven who gain superhuman strength and better eyesight due to its lower gravity.
  • In The Devil is a Part-timer, magic on Earth is very limited compared to Ente Isla. Hence, demons and angels have to use other means.

  • In Digimon Tamers, the Tamers and their Digimon partners can easily Biomerge in the Digital World to reach their Mega levels. In the real world, they cannot Biomerge due to Tamers not being made of data, so they have to do a workaround to invoke this ability.
  • Downplayed in Kinnikuman: By invoking Bergmann's Rule, Lunaight can tower over his opponent. This ability can best be used on Planet Earth, as that is where his ancestors originally came from. He can't use this ability in the Omega Cluster at all because that won't awaken his ancestors' genetics. Still, he's a powerful Chojin, so he doesn't need to rely upon Bergmann's Rule.

Literature

Live-Action TV

Tabletop Games

  • An inverted example from d20 Modern‍'‍s "Urban Arcana" setting: monsters from Dungeons & Dragons fall to Earth as "Shadowkind". Monsters, who are large physical combatants, aren't special on their home world. They, however, pose the greatest danger in the "real" world due to the high density of civilians, weapon restrictions, and the lower power level of heroes (especially heroic magic users). This is especially true of anything with damage reduction that requires magic to bypass it — in D&D one is expected to have a magic weapon by about level 4 and can find ways to have one temporarily from the first level. Still, in Urban Arcana any kind of magic weapon is exceptionally rare and likely archaic even if you find one.
