Power Ideas (specific type of crossover fic)

[myHeadHurts]

One of my favorite type of power crossovers is when a weak/limited/narrow power is moved to another world and allowed to flourish.

Now that I'm writing this all examples are escaping me, but I love to see it.

Stuff like a curse power that is middling in its source material but absolutely stomps in JJK, even if JJK wins the power scaling competition world wise.

What are some powers/people you think would flourish in settings other than their own?

The example that comes to the top of my head is from the old webcomic, erfworld. The protagonist (anagrammed as Parson Gotti) is a normal human summoned by a spell into this fantasy world that's structured like a turn-based strategy game. Everything he encounters in this world looks like a joke or a meme, and at first you think that's just the author throwing winks at the reader and making everything humorous--which it probably was in the beginning--but then then you learn about how magic works in that world, and there's a branch of magic called Signamancy, which is all about interpreting meaning from the way things look. It turned out that in this world, the protagonist was classed as a caster, of the Signamancy discipline, and this is why everything looks like a meme to him. Everyone else who isn't a Signamancer just takes all these memes at face value, as if they're completely normal, but the protagonist can take one look at a character and know exactly what that character is all about. In other words, his real-world power of pop culture and meme lore translated into the fantasy world as a serious and subtle magic not to be underestimated.

For example, he gets to meet the Chief Moneymancer of a side called Transylvito (mafia vampires)
Parson: "You're.... a pimped out Benjamin Franklin?"
Ben: "Actually, my name is Benjamin Franchise"

Or at one point he's sending scout units to spy on a rival side. The scout units look like little green army men. One of them returns, carrying a gift from the enemy. Parson sees that it's a grenade, and he shouts for the unit to quickly throw it away.

Or this sequence:
- "I've been researching Ansom's army. Turns out almost no one in his army can Dance-Fight... wanna know what else I learned?"
- "Lord?"
- "Uncroaked units led by a master-class Croakamancer..."
*His side's Chief Croakamancer comes out onto the battlefield dressed like Michael Jackson in Thriller, backed up by a horde of zombies striking dance poses*
- "...can"
